A complete guide to finishing Zebu cattle in Ogun State, Nigeria

By Eben van Tonder and Christa van Tonder-Berger, 1 June 2026

Introduction

Each Zebu needs 4,000 square metres of land in the main system, planted with Guinea grass (Panicum maximum) before the cattle arrive. A Zebu that arrives at 275 kilograms can gain between 50 and 75 kilograms over 100 days, leaving the farm at between 325 and 350 kilograms depending on conditions. A well-finished 350 kg Zebu gives about 180 kg of carcass meat. Every measurement and every step in this guide is based on what farmers in Africa have done for many years.

Zebu cattle from the north arrive thin and tired. They cannot eat green grass straight away. They must be fed dry grass for 21 days in a staging camp, with green grass added a little more each day, before they can join the main system. The main system is rotational grazing across four camps built around a central water trough.

A simple and inexpensive program, followed by a disciplined producer, can deliver Nigerian breeds in excellent condition. It requires land, Guinea grass, water, shade, salt, and patience. It does not require imported feed, expensive equipment, or veterinary intervention beyond the basics. The system described in this guide has been used by farmers across Africa for generations. What it requires above all is consistency.

Nigerian cattle are generally of poor quality at slaughter — not because the breeds are inherently inferior, but because simple, well-established techniques for ensuring that an animal carries maximum fat and muscle at the time of slaughter have not been maintained. The White Fulani, the Sokoto Gudali, and the Red Bororo are capable animals. Given the right conditions, they finish well and produce a carcass that competes with anything the continent has to offer. The problem is not the cattle. It is the absence of a disciplined finishing program.

Part 1

The Staging Camp

Cattle from the north arrive thin, tired, and used to dry rangeland grass. Their whole life, the grass they have eaten is brown, tough, and low in water. Guinea grass is the opposite: green, soft, and full of water and protein. If new cattle are put straight onto green pasture, three bad things happen. Their stomachs fill with gas, which is called bloat. Their dung becomes loose like water. The strong ones survive but lose weight for weeks. The weak ones die. This is the single biggest cause of loss when buying cattle from the north.

Size of the Staging Camp

Each week about 40 new cattle arrive, matching the 40 cattle that go to slaughter the same week. They stay for three weeks, therefore the staging camp holds about 120 animals at any time. Allow 500 square metres (0.05 hectare) per animal because the grass here is light grazing only, not the main food. So 120 animals need approximately 6 hectares. Build the staging camp at least 50 metres away from the main rotation fences.

Growing the Right Dry Food on Your Own Farm

Grow your own field of Andropogon gayanus, also called gamba grass. This is the same grass that grows wild on the rangelands of northern Nigeria, where the cattle came from. The cattle recognise the smell and the taste and eat it the moment they arrive, so their stomachs do not get a shock. Andropogon grows tall, up to 2 metres. It dries while still standing in the field and stays standing through the dry season. For a 5-cattle-per-day operation, plant a minimum of 2 hectares of Andropogon. For a 10-per-day operation, plant 4 hectares.

Recipe — Planting Andropogon for Dry Feed

Ingredients

• 2 to 4 ha of land near the staging camp, fenced separately from the rotation. Use 2 ha minimum for a 5-per-day slaughter operation; use 4 ha for 10-per-day.
• 5 kilograms of Andropogon gayanus seed per hectare. Buy from CRIN (the Cocoa Research Institute of Nigeria) in Ibadan, or from any tropical pasture seed supplier in Abeokuta or Lagos. Ask for gamba grass.

Method

1. Clear the bush and loosen the soil the same way as for the main grass pasture (see Part 3). Sow at the start of the long rains in April or May, after the first heavy rain.
2. Do not let any animal onto it for the first 4 months. Let the roots get strong.
3. From the second year onwards, cut what you need each week with a sickle or a machete. Cut at chest height. Leave 30 cm of stem standing so the grass grows back. The same area can be cut 3 to 4 times in a year.
4. In the dry season, leave the grass standing. Walk into the field and cut what you need. Standing dry grass is exactly what the new cattle want.

The 21-Day Transition Schedule

This is the heart of the staging camp. Three weeks. Start with all dry food. End with all green food. Change slowly. Every day before letting the cattle onto the green grass, give them at least half an hour of dry hay in the kraal. A full stomach goes slower on the green grass than an empty stomach. The green grass is the danger. The dry hay in the stomach first is the protection.

Period	Green grass access	Notes
Days 1 to 5	None. Kraal only.	Dry Andropogon grass and clean water only. Dung inoculation begins on Day 1.
Day 6	1 hour in the afternoon	Back to dry food after. Give dry hay before releasing each day.
Day 7	2 hours	Same pattern. Increase by one hour every two days through Week 2.
Day 14	6 hours	Half and half phase complete. Always give dry hay before releasing.
Day 18	8 hours	Mostly green. Dry hay remains available in the kraal overnight.
Day 21	All day	Dry hay still available in the kraal at night for any animal that wants it.
Day 22	Main rotation	Move to one of the four main rotation camps. The transition is complete.

Dung in the Water for New Arrivals

This method was shown to me by my grandfather, Oupa Eben. He did not call it rumen inoculation. He called it common sense.

Every morning during the 21 days, add a small handful of fresh dung from a local cow already doing well on your grass to the water trough of the staging camp. One handful in a full trough is enough. The rumen, which is the first stomach of the cow, contains bacteria that break down grass. Different types of grass need different types of bacteria. Cattle from the north carry bacteria suited to dry rangeland grass, but your green Guinea grass needs different bacteria. When the new cattle drink water containing local dung, the local bacteria pass into their rumen. With this method, the rumen adjusts in three to four days. Without it, the adjustment takes two to three weeks, during which time the cattle lose weight and some get sick. The cost of this method is nothing. There is always dung. There is always water.

Recipe — Setting Up the Staging Camp

Ingredients

• 6 hectares of land near the entrance to the farm, at least 50 metres from the main rotation.
• A 2 to 4 hectare Andropogon field next to the staging camp. Fenced the same way as the main camps.
• A kraal at one end with a roof over part of it. About 200 square metres of covered area for 120 animals. Pole walls or low wire walls so the cattle stay in but the air moves through.
• A water trough inside or next to the kraal: 5 metres long, 70 cm wide, 60 cm deep, holding approximately 2,100 litres.
• Shade trees or a shade shelter for 120 animals (300 square metres of shade total).
• Dry Andropogon hay or standing dry grass for 120 animals for 21 days, about 80 bales.
• A wooden salt box with a roof, set on a post. Fresh dung from a local cow each morning.

Method

1. When new cattle arrive at the farm, walk them quietly into the kraal of the staging camp. Do not push or hurry them. They are tired.
2. Fill the feeding troughs with the dry Andropogon. Add water to the water trough. Put one handful of fresh local dung into the water trough.
3. For the first five days, the cattle stay in the kraal area. From Day 6, follow the 21-day schedule. When they come back to the kraal each day, the dry hay is waiting for them.
4. On Day 22, walk them to one of the main rotation camps. Between batches, spread the manure in the kraal and the staging pasture. Let the pasture rest for at least one week before the next batch arrives.

Health Warning Signs During the 21 Days

• Swollen left side like a drum: this is bloat. The animal cannot belch out the gas and can die within an hour. Walk the animal slowly. If it cannot stand, call the veterinarian.
• Loose watery dung beyond Day 10: pull the animal back to the kraal. Give only dry food for two days before trying the green grass again.
• Standing apart from the herd, head down, not eating: pull it aside. Give only dry food and clean water. Watch for one day. If no better, call the veterinarian.
• Heavy fast breathing in the cool of the morning: the animal is sick or in pain. Pull it aside immediately.

Part 2

The Plan

The plan is based on two rotational grazing systems set out by Christa van Tonder-Berger. The points below are her own description, broken into the rules of each system.

Christa’s System 1. The Long Field

The outside of a long field is permanently fenced, while inside the fenced area, only a temporary dividing fence is moved forward daily, or as needed. The size of each newly released grazing section depends on the size of the herd, the animals’ feed requirements, the grass growth, and the soil conditions. The cattle move into each new section by themselves, because the grass is longer and fresher there. The water source stays at the start of the field, provided the cattle can reach it regularly without walking too far.

Christa’s System 2. The Square Field

The whole field is fenced off according to the size of the herd and divided into four equal quarters. The herd grazes the first quarter until it is grazed down enough, then moves to the second quarter. While the second quarter is grazed, the first quarter is maintained: the manure is spread thin as fertiliser, fresh grass seed is sown on patchy areas, and weeds are dug out by the root. The process repeats from quarter to quarter until the cattle return to the first quarter, which has by then recovered and produced new grass.

Which System This Guide Uses

This guide uses the square field. It works better in Ogun State because the water trough sits in the middle where all four camps meet, meaning no camp is far from water. The rotation is run by opening and closing small gates, so no fence is moved each day. One person can manage the whole rotation.

Part 3

How Big Must the Farm Be?

The size of the farm depends on how many Zebu the abattoir wants to slaughter each day. Each Zebu spends 100 days on the farm, and the abattoir slaughters four days every week.

Throughput	Cattle in system (corrected)	Land needed	Carcass per week
5 per day (4 days/week)	~285 animals	~115 ha	3,600 kg
10 per day (4 days/week)	~570 animals	~230 ha	7,200 kg
20 per day (4 days/week)	~1,140 animals	~455 ha	14,400 kg

Part 4

Preparing the Land

The land must be cleared, the soil loosened, the grass seed sown, and the fence built. From the day the bush is first cleared, it takes six months before any cattle can walk on the new grass. Plan the work to fit the rainy season.

Step 1. Clear the Bush

Take a machete and a hoe. Cut down the bushes and the weeds, pile them up, burn them, and spread the ash back over the cleared ground. Leave the big shade trees standing: mango trees, palm trees, baobabs. The cattle will need them in two years, because each tree shades 20 to 25 animals when they are grown. Pull out small tree stumps with the hoe. Two workers with hoes and machetes can clear one hectare in about a week.

Step 2. Loosen the Top Soil

Take a hoe. Break the top of the soil to about 15 centimetres deep — one hand-span. Not deeper. The grass roots will go down themselves once they are growing. If the soil is very hard, water it the day before so the hoe goes in easily.

Step 3. Sow the Grass Seed

Recipe — Sowing Grass for One Hectare

Ingredients

• 5 kilograms of Guinea grass seed (Panicum maximum). Ask for Mombasa or Tanzania variety at the agricultural supplier in Abeokuta or Lagos.
• 1 cloth bag for the seeds. A thorny branch or an empty grain sack for covering.

Method

1. Sow at the start of the long rains, in late March or early April, after the first heavy rain has wet the soil.
2. Walk slowly across the prepared field, throwing handfuls of seed left and right. Cover the ground evenly. Walk a second time at right angles to the first.
3. Drag a thorny branch or an empty grain sack across the ground. This pushes a thin layer of soil over the seed. Seeds should be no deeper than the thickness of a finger.
4. Green shoots appear in 7 to 10 days. The field is fully covered in one month. Do not let any animal onto the grass for four months.

Step 4. Put Up the Fence

Recipe — Fencing One Field of 15 Hectares (Four Camps)

Ingredients

• Wooden posts cut from local hardwood. Each post 2 metres long. Approximately 280 posts for the outside fence, plus approximately 140 more for the inside fences. Total approximately 420 posts.
• Barbed wire or smooth wire. Approximately 6,200 metres for the outside fence at 4 strands, and approximately 3,100 metres for the inside fences. Wire staples. About 1 kg per 100 posts.
• A post-hole digger or a sharp iron bar. A hammer.

Method

1. Decide the outside corners of the whole field. Drive in a tall stake at each of the four corners. Stretch a line of string from corner to corner along each outside edge.
2. Dig the first post hole at one corner to 60 cm deep. Set the first post, pack the soil hard around it. Measure 5 to 6 metres along the string line and repeat until the whole outside boundary has posts.
3. Stretch the first strand of wire along the bottom of the posts, 30 cm above the ground. Pull it tight, then staple it to each post. Add the second strand at 60 cm, the third at 90 cm, and the fourth at 120 cm above the ground.
4. Build the inside fences to divide the field into four equal parts. The water trough goes in the middle. Leave a gate of about 1 metre wide in each inside fence at the spot where the camp meets the centre.

Part 5

The Water

The water trough sits in the middle of the field, where the four camps meet. No matter which camp the cattle are in this week, the water is at the corner of that camp. The cattle walk to drink several times a day and walk back through the same gate.

Recipe — Water Trough for 100 to 150 Zebu

Ingredients

• A long rectangular trough: poured concrete, cut and welded steel, or a halved 200-litre drum laid lengthwise. Total length 4 metres. Total width 70 centimetres. Depth 60 centimetres. Rim height 50 to 60 centimetres above the ground. Actual capacity approximately 1,680 litres.
• A water inlet pipe with a float valve. A drainage plug at the bottom for cleaning. Hard-packed ground around the trough, 2 metres wide on each side.

Method

1. Build the trough at the centre point where the four camp fences meet. Two long sides face two of the camps. The other two sides face the other two camps.
2. Connect the inlet pipe to a borehole, a rainwater tank on a stand, or a stream-fed tank uphill. Test that the float valve closes when the trough is full.
3. The water source must refill the trough completely two to three times a day. Each Zebu drinks about 35 litres a day in the cool season and up to 45 litres a day in the hot season. For 100 cattle, that is 3,500 to 4,500 litres per day.
4. Eight cattle can drink at the same time, four on each side. Clean the trough once a week: pull the drain plug, scrub the inside with a brush, refill.

Part 6

The Shade

Zebu cattle handle heat better than European cattle for several reasons. Their hump is a fat and energy reserve that sustains them through periods of feed scarcity, not a cooling organ in itself. Heat dissipation comes from their loose, pendulous dewlap and the large surface area of their thin, finely attached skin, which increases convective cooling, and from a higher density of sweat glands than taurine cattle possess. Their short, sleek coat also reduces solar heat gain. Together these traits allow them to maintain normal body temperature and appetite in conditions that would severely stress European breeds. Even so, Zebu need shade in the middle of the day in Ogun State, when the temperature passes 32 degrees Celsius. Cattle in full sun all day eat less and grow more slowly.

Recipe — Shade for One Camp with 25 to 40 Zebu

Ingredients

• Big shade trees. A grown mango, palm, or baobab shades enough ground for 20 to 25 animals.
• Or build a shelter: four wooden posts each 3 metres long, six wooden cross-beams each 4 metres long, and roof material such as palm fronds, thatch grass, or corrugated iron.

Method

1. Allow 2.5 square metres of shade per animal. For 25 animals, that is about 62 square metres. A shelter 8 metres by 8 metres is sufficient.
2. Dig four post holes each 80 cm deep. Set each post upright and pack the soil hard. Lay the cross-beams between the tops of the posts and lash them in place with wire. Lay the roof material and tie or nail it down.
3. The roof should be at least 2.5 metres above the ground. Place the shelter near the water trough, about 10 metres away.

Part 7

Moving the Cattle Every Week

Every Monday, on the same day, move the cattle from one camp to the next. Monday sets the rhythm for the week. When the cattle leave a camp, spread the manure evenly with a hoe or a rake. Where the cattle made tracks and the soil is bare, throw a handful of fresh grass seed.

For larger herds: split the animals into groups of 30 to 40. Each group has its own four-camp rotation. The water source can be shared between two adjacent rotations if it is in the corner where the rotations meet.

Part 8

Making Hay for the Dry Season

From November to March, the rains stop and the grass stops growing, but the cattle still need to eat. So in October, while the grass is still tall and green and the weather is starting to dry, cut hay. Hay is just dried grass. Sun-dried grass keeps for ten months in a dry shed.

Recipe — Making Hay for the Dry Season

Ingredients

• A field of Guinea grass at first flowering, after 6 to 8 weeks of growth.
• A sickle or a machete for cutting. A wooden fork or a strong stick for turning the drying grass.
• Sisal twine or strong rope for tying the bales. A clean dry shed off the ground, with a roof, for storage.

Method

1. Wait for three days of clear, dry weather. Do not cut if rain is expected in the next 72 hours.
2. Cut the grass between 7 and 9 in the morning, after the dew has burned off. Cut close to the ground. Spread the cut grass in a thin layer across the field, no thicker than 15 centimetres. Turn the grass twice a day.
3. After 2 to 3 days, test using the hand test shown above. When it tests ready, gather the cured hay the same day. Tie into bundles of 10 to 15 kilograms each. Stack in a dry shed, off the ground on wooden planks.
4. For 100 cattle through a five-month dry season, you need about 6,000 bales (60 to 90 tonnes of hay).

Part 9

Salt Licks

Cattle need salt because grass alone does not contain enough. Cattle without salt grow slowly, eat less, and develop rough coats. The three options below are in order of increasing complexity and mineral content. Option 1 is enough for the basic mineral requirement. Options 2 and 3 add extra minerals where the materials are available.

Option 1. Loose Salt in a Box

Recipe — Salt Box for One Camp

Ingredients

• A wooden box: an old crate or a soap box, any size from 30 cm by 30 cm up to 50 cm by 50 cm. Not metal, because metal makes the salt go bad.
• 1 bag of cooking salt from the market. Two short wooden legs for the box, knee high. Four sticks for the roof legs. An old metal sheet or four palm fronds for the roof.

Method

1. Set the box on its short legs near the water trough. Build a roof above it, sloping slightly so rain runs off the sides. Pour the bag of salt into the box.
2. Refill the box when it gets low. One bag of salt feeds 30 cattle for about one month. Build one in each camp, near the central water trough.

Option 2. Salt Mixed with Termite Clay

Mix salt with clay from a termite mound and press it into a block. The clay holds the salt together so the cattle cannot eat it too fast, and the termite clay also brings extra minerals. This is what Karimojong farmers in Uganda do. If you cannot find a termite mound, clay from a stream bank or a wet hollow works too.

Recipe — Salt Block with Clay. Makes 4 Blocks.

Ingredients

• 2 buckets of clay from a termite mound (sifted through mosquito net to remove stones).
• 1 bucket of cooking salt. Water to make a thick paste. 4 empty paint tins for moulds.
• Optional: a clean flat pan and a small fire for roasting the clay first, to kill any small living things.

Method

1. Mix the clay and the salt together dry in a big bucket. Stir until the salt is even through the clay. Add water slowly while stirring. Stop when the mixture is like wet sand and holds its shape when squeezed.
2. Press the wet mixture firmly into each tin. Set the filled tins in a sunny spot. Leave for two weeks.
3. After two weeks, turn the tin upside down and tap. The block falls out, hard as a brick. One block lasts about two months for 10 cattle.

Option 3. Salt Block with Termite Clay and Burnt Bone

Bones are full of minerals. If you have access to the abattoir, this is the best lick to make. The bones are free, and the cattle that get this lick grow heavier muscles and stronger bones. Their carcasses sell for a better price. This recipe is from the Karimojong people in Moroto, Uganda.

The first step is to burn the bones to ash. After 30 minutes the bones turn black and are not ready. After one hour they turn grey and are still not ready. After two hours they turn white and crumbly, and they are ready to crush.

Recipe — The Full Mineral Salt Block. Makes About 12 Blocks.

Ingredients

• 8 cups of bone powder (from burning and crushing abattoir bones as described above).
• 4 cups of cooking salt.
• 40 cups of termite mound clay (sifted and roasted in a pan to kill any small living things).
• Water to make a thick paste. 12 empty tins for moulds.

Method

1. Mix the bone powder, salt, and clay together dry in a big bucket. Stir until even. Add water slowly while stirring. Stop when the mixture is like thick wet sand.
2. Press the wet mixture firmly into the 12 tins. Set in a sunny spot, off the ground. Leave for 3 to 4 weeks. This block takes longer to dry because the bone makes it harder.
3. Once dry, turn out the blocks. One block provides one day’s mineral needs for approximately 8 cattle. Make a new batch every day, or maintain a rolling supply with batches at different stages of drying so that finished blocks are always available.

Where to Place the Salt

Build a simple stand in each camp. A wooden post fixed in the ground, with a flat top at the height of the cow’s mouth, about 80 cm from the ground. A small roof above to keep the rain off. The block sits on top of the post. Put the stand near the water trough but a few metres away, so the cattle walk past it every time they drink.

Part 10

Using Blood from the Abattoir as Fertiliser

Blood is high in nitrogen and nitrogen makes grass grow tall and green, therefore blood from the abattoir can replace bought fertiliser if it is handled correctly. Fresh blood cannot be put directly on the field because it burns the plants, it smells strongly for several days and attracts flies, and any disease in the slaughtered animal can spread into the soil. The solution is composting. Blood mixed with a dry filler and kept under cover for four to six weeks turns into a safe, dry, brown fertiliser. The heap heats up inside, and this heat kills disease and removes the smell.

Recipe — Blood and Sawdust Compost

Ingredients

• 1 bucket (about 20 litres) of fresh blood from the abattoir, collected the same day.
• 3 buckets of dry filler. Sawdust from a carpenter is best. If sawdust is not available, use chopped dry grass, chopped rice straw, dry palm fronds, or old dry leaves.
• Banana leaves, palm fronds, or an old piece of plastic for the cover. A fork or a hoe for mixing.

Method

1. Pile half of the dry filler on the ground. Pour the blood evenly over the top. Cover with the rest of the dry filler. Mix with the fork so that the blood soaks into the dry material until no red is visible. Shape into a heap like a small hill.
2. Cover with banana leaves, palm fronds, or plastic. Tuck the edges under the bottom of the heap. Leave for four to six weeks.
3. After four weeks, push a stick into the middle of the heap. If the colour is dark brown all the way through with no red, and there is no bad smell, the compost is ready. If it still smells or has red colour, cover again and wait two more weeks.
4. Spread thin on the resting camp that the cattle just left. One bucket of compost covers a piece of ground about 5 metres by 5 metres. In two to three weeks, the grass comes back greener and thicker than before.

Safety

• Wear gloves or wash your hands well after handling fresh blood or wet compost.
• Do not let children near the heap.
• Do not put the heap close to a well or near the drinking water trough. Pick a spot downwind from the kraal.
• Do not use the compost until it has been sitting for at least four weeks and the smell has gone. The waiting time is what makes it safe.

Part 11

The Daily Routine

The system runs because someone does the same small things every day. None of it is hard. All of it is necessary.

When	What to do
Every morning	Check the water trough. Is it full? Is the float valve working? Is the water clean? Walk and count the cattle. Check the salt block in the camp. Check the fences.
Every Monday morning	Move the cattle to the next camp. Spread manure in the vacated camp with a hoe or rake. Throw fresh seed on any bare patches. Pull out any large weeds by the root.
Every week	Clean the water trough. Add a handful of local dung to the staging camp water each morning (for new arrivals).
Every month	Walk and inspect the outside fence of the whole farm.
Every October	Make hay. One to two weeks of cutting and drying gives the farm 6,000 bales for the dry season.
After every slaughter day	Collect bones from the abattoir. Collect blood in clean buckets. Start a new compost heap the same day. Prepare a new batch of Option 3 salt blocks.

Part 12

Expected Weight Gain

A Zebu arriving at 275 kg can gain between 50 and 75 kg over 100 days and leave the farm at between 325 and 350 kg. The upper end of that range requires well-managed rotational grazing, good water, mineral supplementation, and cattle that have fully adjusted after the staging period. Weight gain is not constant. The stomach is still adjusting in the first two weeks, and the muscles are recovering from the journey. Frame-building comes in the middle weeks. Fat-laying comes last.

Phase	Weight gain per week	Notes
Weeks 1 to 2	About 3 kg per week	Stomach still adjusting after the staging period. Muscles recovering from the journey.
Weeks 3 to 8	About 5 to 6 kg per week	Frame-building phase.
Weeks 9 to 14	About 7 kg per week	Fat-laying phase.
Total over 100 days	50 to 75 kg	275 kg on arrival, 325–350 kg at slaughter. A well-finished 350 kg animal gives approximately 180 kg carcass (51–52%). A 325 kg animal gives approximately 160–165 kg.

If cattle are not gaining as expected after three weeks in the main rotation, check in this order: Is the water clean and always available? Is the grass still growing? If a camp has been grazed and three weeks later the grass is still short, the rotation is too tight. Add a fifth camp or reduce the herd. Is the shade sufficient (2.5 m² per animal)? Is the salt lick stocked? Are there parasites? If the answer to the first four is yes, call the veterinarian.

Part 13

What Not to Do

Do Not Skip the Staging Camp

New cattle straight onto green pasture die from bloat or get loose dung that takes weeks to fix. The three weeks in the staging camp save more cattle than any other single thing on the farm.

Do Not Leave the Cattle in One Camp Too Long

If the cattle stay in Camp 1 for three weeks instead of one, they eat the grass down to the soil. The grass dies and the soil washes away when the rains come. Move the cattle every Monday. Every Monday.

Do Not Skip the Rest Period

Three weeks of rest between grazings is what makes the grass come back. If the cattle enter a camp that has not had three weeks of rest, the grass weakens. Within a few months the camp turns to dust and bare ground.

Do Not Let the Water Trough Run Dry

A Zebu without water for one day eats less, gains nothing, and starts to lose weight. A Zebu without water for two days gets sick. A Zebu without water for three days dies. Check the trough every morning.

Do Not Put the Staging Camp Next to the Main Camps

New arrivals may carry sickness from the road. Keep them separate until they have settled. A gap of at least 50 metres between the staging camp fence and the main rotation fence is enough.

Building Order

Build the farm in this order. Do not skip steps and do not start the next step until the one before it is finished.

Timeline	Work
Month 1 to 2	Clear the bush. Loosen the soil. Sow Guinea grass in the four main camps. Sow Andropogon in the staging feed area.
Month 3 to 5	While the grass grows, put up the outside fence. Divide into four camps. Build the central water trough. Build the staging camp fence at least 50 metres from the main rotation.
Month 5	Build the shade shelters in each camp (or identify the big shade trees). Build the salt lick stands. Make the first batch of salt blocks.
Month 6	The grass is now four months old. Cut the first hay from any extra Guinea grass. Stack in the dry shed.
Month 7	Bring in the first 40 cattle. Place them in the staging camp. Start the 21-day transition. Begin the dung-in-water method on Day 1.
Month 8	The first 40 cattle move from the staging camp to the main rotation. Bring in the next 40 cattle to the staging camp.
Month 10	The first 40 cattle reach 100 days. Send 10 per day to the abattoir over four days. Start collecting bones and blood from the abattoir. Begin the first blood compost heap. Start making salt blocks with bone ash.
Month 11 onwards	The system is now running. Forty in, forty out, every week. Forever.

Salt block with clay	1 block per 10 cattle per 2 months
Salt block with bone (Option 3)	1 block per 8 cattle per day. Make a new batch every day for 100 cattle.
Blood compost	1 bucket of blood plus 3 buckets of sawdust. 4 to 6 weeks under cover.
Weight gain	50–75 kg over 100 days. About 3 kg per week early, 5 to 6 kg middle, 7 kg late at the upper end.
Carcass yield	50–52% for a well-finished animal. A 350 kg Zebu gives approximately 175–183 kg carcass. Unfinished animals yield 43–47%.

Independently confirmed by the transfaunation literature cited above. Practical field knowledge predating the formal scientific literature on rumen inoculation. The practice represents the kind of applied observation that good African farming has produced for generations.

Review confirming that heat tolerance in Zebu derives from loose skin, large dewlap, higher sweat gland density, and short coat. The hump is a fat and energy reserve, not a primary thermoregulatory organ.
