🐄 Feeding Through the Dry Season

Every other lever in this course - bull soundness, breed choice, calving season, culling - can be pulled correctly and still be undone in about four months of the year. A review of the constraints on African livestock productivity names inadequate dry-season grazing and feed as probably the single most important limit on output. Not disease. Not genetics. Feed, in the dry months.

Understand why it hits so hard, because the damage is indirect and that is what makes it easy to miss.

When grass runs short, a cow does not simply get thinner and then recover. She spends her body reserves to stay alive and to keep milking, and once those reserves are low her body stops the thing it can most afford to stop: reproduction. A cow in poor condition after calving does not come back into heat on time. She does not conceive in the mating season. She calves late next year, or not at all. So the dry season you survived becomes a calf you never got, twelve to eighteen months later, when the connection is no longer obvious.

The South African weaning trial in this course's reference gives a clear demonstration of the same mechanism working through the calf rather than the season. Dams still nursing calves to conventional weaning at 205 days had a rebreeding pregnancy rate of 84 percent and a calving interval of 419.3 days. Dams whose calves were weaned early at 90 days, taking that drain off them, reached a 94 percent pregnancy rate and a calving interval of 347.6 days. Same herd, same breed, same trial. Take the nutritional load off the cow, and she rebreeds sooner. Leave it on her, and she does not.

That trial was about weaning age, not drought. But the biology it shows is exactly the biology of a hard dry season: a cow competing between her own body, her current calf, and her next pregnancy will give up the pregnancy first. Note also the dam weights in the same trial - 380.2 kg at calving in the early-weaned group against 481.2 kg in the conventional group - a reminder that dam body weight and condition are measurable things that differ substantially between management systems, not vague impressions.

Now the timing problem, which is the practical heart of this module. The dry season announces itself long before it bites. Every farmer knows roughly when the rains stop where they live. And yet the commonest pattern on smallholdings is that nothing is done until cows are visibly thin - which is the one moment when the options are worst. By then the grass is gone, so you cannot conserve any. Everyone else is also short, so purchased feed is expensive and scarce. Everyone else is also selling, so cattle prices are at their weakest. You are making your most expensive decisions with the least money and the least time.

The rule this module is built on is therefore simple and unpopular: a dry-season feed plan must be made before the dry season starts, using surplus grown during the rains. Grass reserved by grazing management, grass cut and stored, crop residue collected and kept dry - all of these have to be arranged in the season of plenty, because the season of plenty is the only time the raw material exists.

What that means in your calendar is that the busiest month of the rains, when everything is green and the cattle look wonderful, is the month to walk the farm with a pencil and decide which block will not be grazed again until August, and where the maize stover will be stacked.

One more honest point. Not every dry season can be planned through. Some droughts are simply bigger than any farm's reserves. The plan is not a promise that you will never be short. The plan is how you find out that you will be short while you still have options - while you can still sell animals at a decent price, wean early by choice, or arrange grazing elsewhere. Lesson 6 of this module is entirely about that.

A feed plan that is not written in numbers is a hope. This lesson turns it into arithmetic you can do on one page.

You need three things: how many days the gap is, how many Large Stock Units you are feeding, and how much dry matter one LSU eats a day.

You worked out the first in the last lesson. You worked out the second in the grazing module - every animal that eats on your land, converted to LSU using the 450 kg reference animal, including small stock at about 0.12 to 0.14 LSU each. The third comes from the same rangeland source: one LSU needs approximately three percent of its body weight in dry matter per day, which for the 450 kg reference animal is about 13.5 kg a day, or roughly 4,900 kg a year.

Now the budget. Take a herd of 10 LSU and a feed gap of 120 days.

1. Daily demand: 10 LSU multiplied by 13.5 kg equals 135 kg of dry matter a day.
2. Gap demand: 135 kg multiplied by 120 days equals 16,200 kg, or about 16 tonnes of dry matter.

Sixteen tonnes. That is the size of the problem, and until you have written that number, you cannot tell whether a stack of stover in the corner of the yard is a solution or a gesture.

Be careful about what this budget is and is not. It is a total quantity of feed, in dry matter. It is not a balanced ration. An animal can eat 13.5 kg of dry, stemmy, low-protein dry-season grass and still lose weight, because quantity and quality are separate problems. Balancing protein, energy and minerals with a compounded feed is the Feed Formulation course's job, and if your budget shows the herd will get enough bulk but the feed is very poor, that is exactly when to go to that course or to an animal nutritionist.

The next step is the supply side, and here the budget usually meets its first real difficulty. To know how many kilograms a hectare of reserved standing grass will give you, or how much a stack of hay weighs, you need yield figures - and this course cannot give them to you. No African-measured yield, quality or cost figure for hay-making or silage-making at smallholder scale was retrieved to a standard worth teaching as a number. That is a real gap and it is stated rather than filled.

So you measure. This is genuinely doable.

• For a stack or a bale: weigh a representative sample. A bathroom scale, a hanging spring balance from a market, or a shop scale will do. Weigh five bales, take the average, multiply by the number of bales.
• For stover: fill one sack, weigh it, then count sacks.
• For standing grass in a reserved block: this is harder, and it is where an extension officer earns their keep. Ask them to help you estimate available forage on that block, or use the reverse method below.

The reverse method is the most practical tool a smallholder has, and it needs no yield table at all. Put the herd onto the reserved block and count the days until it is grazed down to the point where you must move them off. Write down the date in, the date out, and the LSU total. Next year, on the same block in a similar season, you know roughly what it gives you: not in kilograms, but in animal-days, which is the only unit you actually need.

Now close the budget. Suppose you have measured 6 tonnes of stover and estimate your reserved block will carry the herd for 40 days.

1. Reserved block: 40 days multiplied by 135 kg a day equals 5,400 kg.
2. Stover: 6,000 kg.
3. Total supply: 11,400 kg against a demand of 16,200 kg.
4. Shortfall: 4,800 kg, which at 135 kg a day is about 36 days short.

Thirty-six days short is a fact you can act on in April. It is a crisis in September. You can close it by conserving more, buying feed while it is still cheap, arranging grazing elsewhere, weaning early, or selling animals now while they and the market are still in decent shape - and reducing the herd by 2 LSU cuts daily demand by 27 kg, which alone closes a large part of the gap.

That is the entire value of a feed budget. It does not make grass grow. It tells you the truth early enough that your cheapest options are still open.

The cheapest dry-season feed on any African smallholding is grass that grew in the rains and was never grazed. It needs no machine, no baler, no shed and no fuel. It needs one decision, made early: this block is closed.

That is standing hay. The grass cures where it stands, drying off as the season turns, and the block becomes a feed store that harvests itself. It is recognised in the wider literature as a dry-season conservation option alongside cut hay and silage, and for most smallholders it is the one that is actually achievable this year.

How it works in practice. During the growing season you close one block to grazing - by herding, by a thorn barrier, by a fence if you have one, or by agreement on communal land. The grass grows out fully, sets seed, and cures standing. Then, in the dry months, you open it and let the herd graze it down.

What you gain, beyond feed in the mouth.

• The block gets a long rest. This is the same rest that Module 5's rotation lesson said grass plants need to rebuild root reserves. Reserving a block for standing hay and resting the block are the same act, viewed from two directions.
• The grass sets seed. A block grazed hard every year rarely gets to seed. A reserved block reseeds itself, which slowly improves species composition.
• No cutting labour. Cutting, drying, carrying and stacking hay is heavy work, and labour demand is one of the documented reasons dry-season feed techniques get abandoned by farmers who tried them.

What you lose, and it is real. Standing hay is dry, stemmy, mature grass. Feed quality falls as grass matures - the protein drops away and the fibre rises. So standing hay keeps animals alive and full, but it does not on its own put on weight or restore condition. It is a survival feed, not a growing feed. Where a genuine protein or energy deficit needs correcting with a purchased concentrate or supplement, that is the Feed Formulation course's subject, and this is the moment to go there rather than guess.

Now the risks, because a reserve you lose is worse than no reserve - you were counting on it.

1. Fire. Standing dry grass burns. A reserved block is exactly the most flammable thing on the farm at the driest time of year, and a fire started by a neighbour, a road, a smoker or lightning can take your whole reserve in an hour. A firebreak around the block is cheap insurance and worth the labour.
2. Other people's animals. On communal or unfenced land a reserved block is visible, tempting and unguarded. This is not solved technically. It is solved by agreement - the reserve has to be understood and respected by the people who graze around you, which means talking to them before you close the block, not after someone's herd is in it.
3. Trampling and waste. If you turn the whole herd into a large reserved block at once, they walk on much of it, dung on it and spoil it while eating only part. Opening the block in strips or sections, moving the herd across it, wastes far less. Even a single moved line of herding, or a temporary barrier moved every week or two, makes a large difference.
4. Termites and weathering. Grass left standing through a long dry season loses material to termites, wind and rain-splash. Standing hay does not keep indefinitely from one year to the next.

How to choose the block. Reserve land you can control and reach in the dry season, not your furthest corner. Choose a block with a decent proportion of the grasses your cattle actually eat, not the one that is already degraded, because closing a block does not make good grass appear where none was. Prefer a block near water, since dry-season cattle grazing far from water waste energy walking. And do not reserve your worst block just because it is the one you can most easily do without - the reserve is the feed your breeding cows will live on when it matters most.

Finally, record it. Date closed, date opened, number of LSU turned in, date the herd had to come off. Do that for three years and you know what that block delivers in animal-days, in a good year and a bad one. That is the number your feed budget in the last lesson needs, and it is yours alone.

Standing hay leaves the grass in the field. The other two options take the crop off the field and store it, and they are worth understanding even if you never make them yourself, because you will be offered them, sold them, and told about them.

Hay is forage cut and dried. You take grass or a forage crop at a suitable stage of growth, cut it, let it dry down in the sun until the moisture is low enough that it will not rot or heat, and store it under cover. Preservation works by dryness. Nothing can grow in it because there is not enough water. The enemies are rain during drying, storing it before it is dry enough, and rain or damp on it in storage.

Silage is forage preserved wet. You take a crop, usually a green one with plenty of sugar such as maize or sorghum, chop it, pack it very tightly to drive out the air, and seal it - in a pit, a trench, a drum or a plastic bag. With the air excluded, bacteria ferment the sugars into acid, and the acid preserves the crop the way sourness preserves any food. Preservation works by acid and by the absence of air. The enemies are air, poor compaction, a leaking seal, and a crop with too little sugar or too much moisture to ferment properly.

That is the honest structural difference: hay is preserved dry, silage is preserved sour and airless. Everything else about them follows from it.

Which fits a smallholding? Ask three questions.

First, the weather at cutting time. Hay needs a run of dry days to cure. If your surplus grass is at its best in the middle of the wet season, hay is difficult and you will lose crops to rain. Silage does not need dry weather, which is precisely why it exists.

Second, labour and equipment. Cutting, turning, carrying and stacking hay is heavy, sustained work. Chopping and packing silage is heavier still in a short burst, and doing it well needs a chopper or a great deal of labour, plus something airtight enough to seal. Both are real work at the busiest farming time of year.

Third, storage. Hay needs a dry place, off the ground, protected from rain and termites. Silage needs a container that will stay sealed for months and that you can open without spoiling the rest.

Now the part this course must be straight with you about. You want to know the moisture percentage for safe hay storage, the growth stage to cut at, and the additive rates for silage. This course does not give you any of those numbers. No African-measured yield, quality or cost figure for hay-making or silage-making at smallholder scale was retrieved for this reference to a standard worth teaching, and the specific technical thresholds - safe storage moisture, cutting stage, silage additive rates - belong properly to the Feed Formulation course or to a dedicated forage-conservation source that was not obtained here.

That matters more than it might sound. Hay stored too wet does not merely lose quality - it heats, moulds, and in bad cases catches fire in the stack. Silage that is not sealed or not sour enough spoils and can make animals ill. These are exactly the numbers where a plausible-sounding guess from a course writer could cost you the crop or the animal. So the instruction is: get them from your extension service, a forage or dairy specialist, an agricultural college in your country, or the Feed Formulation course, and get them for your own crop and climate.

What you can act on now, without any of those numbers.

• Start very small. Make one drum or one small pit of silage, or a few bales of hay, in a year when you do not depend on it. Learn what your crop does, what your weather does to it, and whether your family can actually do the work at that time of year.
• Open it and look. A trial batch you never open teaches you nothing. Open it, smell it, feel it, and offer it to a few animals before you build a plan around it.

• Cost the labour honestly. The most consistent finding about dry-season feed techniques in the reference material is not that they fail biologically. It is that farmers stop doing them because of labour and input access. A technique your household will not repeat next year is not a plan.
• Prefer the option you can repeat. A modest amount of standing hay and stover, collected every year without fail, beats an ambitious silage project done once.

On a mixed crop and livestock smallholding, the dry season arrives at the same time as something useful: the crop is off, and the field is full of stover. Maize stalks, sorghum stalks, groundnut and bean haulms, and similar residues are a widely used dry-season roughage source, and they are already yours.

Used properly, residues are the backbone of many smallholder dry-season plans. Used carelessly, most of the value walks away. Some plain rules first.

• Collect it. Stover left standing in the field is trampled, rained on, blown away and burnt. Cutting and stacking it under cover holds far more of it.
• Keep it dry. Wet stover moulds. A simple raised stack with a roof of grass or old sheeting beats a heap on the ground.
• Ration it. If you throw a week's stover in at once, cattle sort through it, eat the leaf and soft parts, and trample the stalks into the ground. Feed it a day at a time, in a rack or on a clean surface, and you will get far more days out of the same pile.
• Be realistic about quality. Stover is bulky, dry and low in protein. It fills an animal. It does not, on its own, put on condition.

That last point is why urea treatment exists. Treating maize stover with urea raises the nitrogen content and the palatability of an otherwise very poor roughage. The reference material for this course contains a Zimbabwean study of exactly this technique, and it is one of the most instructive datasets in the whole course - not because of what the technique does, but because of what happened when real farmers were asked to use it.

Among farmers who adopted the technology, the reported results were strong. Ninety-seven percent reported increased feed intake. Ninety-three point nine percent reported improved milk production. Eighty-seven point eight percent reported improved liveweight gain. On those figures, the technique works, and the farmers who used it said so.

Now the second half of the study. Only 20 percent of untrained farmers adopted the technique at all. Among farmers who had been specifically trained in it, only 38.8 percent were still using it. Nearly two in three trained farmers stopped.

Why did they stop? The study asked, and the barriers named were not about the animals.

• Lack of extension follow-up: 87.9 percent of respondents.
• High labour demand: 78.8 percent.
• Difficulty accessing urea fertiliser: 72.7 percent.

Sit with that for a moment, because it is the most important lesson in this module and it applies far beyond urea treatment. A dry-season feed technique that demonstrably works - by the testimony of the farmers who used it - can still fail in practice for reasons that have nothing whatever to do with animal science. Labour, extension support and input access are as much a part of whether something works on a real smallholding as the biology is.

So when you evaluate any feed technique offered to you - by a trader, a project, a neighbour or a course - ask the three questions that this study exposes. Who will do the work, in the busiest month, every year? Where will I get the input, and what happens in a year when it is not in the shops? And who will I ask when it goes wrong in year two, when the training visit is long past?

A technique that survives those three questions on your farm is worth adopting. One that does not will look excellent for one season and be gone by the third.

Now the honest gaps. The reference gives the adoption and reported-benefit figures above but not the resulting kilogram weight gain, not the nitrogen-content improvement achieved, and not the cost of the urea treatment. Those were not retrieved for this course, and no substitute figures are supplied here. If you want to know what urea treatment would gain you in kilograms and cost you in money, that has to come from your national agricultural research institute or extension service, for your own crop and your own urea price.

One serious safety point stands regardless. Urea is a nitrogen fertiliser, and urea and other non-protein nitrogen sources can poison cattle if fed wrongly - in the wrong amount, in the wrong form, or dissolved in drinking water. This course gives no urea rate, no mixing instruction and no inclusion level, because getting it wrong kills animals. Correct rates and safe handling must come from a qualified animal nutritionist, your extension service, or the Feed Formulation course, and never from a neighbour's recollection or a course written for another country.

Some dry seasons are bigger than any farm's reserves. A plan does not prevent that. What a plan does is tell you early, while you still have choices worth making. This lesson is about making those choices well.

The first principle is that in a feed crisis, every option gets worse with time, and one of them - selling animals - gets worse fastest. When rain fails across a district, everyone destocks at once. Prices fall. The animals themselves lose condition and weight, so you are selling fewer kilograms at a lower price per kilogram, twice penalised. A farmer who sells in the first month of a bad season and a farmer who sells in the fourth are not doing the same thing at all.

So set triggers, in writing, before the season starts. A trigger is a fact that forces a decision, not a feeling. For example: if my reserved block is opened before a named date; if the herd's body condition falls below a level I have written down; if the rains have not come by a named week. When a trigger is hit, the pre-agreed action happens. The purpose of writing it in advance is that in the moment you will not want to sell, and a plan made in a calm month is more honest than a decision made in a bad one.

The second tool is early weaning. This course's reference contains a South African Bonsmara trial that quantifies the trade-off exactly. Calves weaned early at 90 days had an adjusted weaning weight of 210.4 kg and an average daily gain to 205 days of 889 grams. Calves weaned conventionally at 205 days reached 237.1 kg and 992 grams a day. So early weaning cost each calf about 27 kg of weaning weight and about 103 grams a day of growth.

What it bought was on the cow's side. Early-weaned dams reached a 94 percent rebreeding pregnancy rate against 84 percent, and a calving interval of 347.6 days against 419.3 days - roughly 72 days shorter. And on a per-hectare basis in that trial, conventional weaning still produced more total weaner per hectare, 115 kg/ha against 91 kg/ha.

Read that honestly, because it does not say what people often claim it says. In that trial, under those pasture conditions, early weaning did not pay on a per-hectare basis - the weaning weight it cost outweighed the rebreeding it bought. It is one trial, one breed, one set of pastures, and it must be taught as evidence that the trade-off exists and which direction it runs, not as a recommendation to wean at any particular age.

But here is why it belongs in a drought lesson. That trial's baseline was adequate pasture. A farmer in a real feed crisis is not choosing between 91 and 115 kg per hectare. They are choosing between a calf weaned early, and a starving cow that will not rebreed at all, dragging a calf that is not growing anyway. Early weaning is a recognised drought-management tool for exactly that reason, even where it costs weaning weight in an average year. The calf, being small, is far cheaper to feed separately than the cow-and-calf pair is to carry together.

The third tool is culling in order, and the order should be written down before you need it. Working from the culling logic in this course, the sequence most farms should use is:

1. Animals that were already culling candidates: open cows at the end of the breeding season, cows that have lost two calves in your records, and old cows with failing teeth, udders or legs. In a drought these leave first, and you were going to sell them anyway.
2. Animals with no productive future in the herd: surplus steers, poor-tempered animals, and any animal you would not choose to breed from.
3. Lower-priority breeding females: later-calving cows, and heifers you have not yet committed to.
4. Last of all, your core breeding females and your bull. These are the herd's future output, they are the hardest to replace, and rebuilding a breeding herd takes years.

What this ordering protects is your capacity to produce calves when the rains return. A herd that sold its best cows and kept its unproductive ones has survived the drought and lost the business.

Four more practical points.

• Small stock and cattle compete for the same feed. If you counted them in your LSU total, count them in your destocking too.
• Reducing the herd cuts demand immediately and permanently for the rest of the season. Two LSU removed from a 10 LSU herd cuts daily demand by 27 kg of dry matter, every day, until the rains.
• Do not spend your last money on feed for an animal you were going to cull. That is buying grass to grow a loss.
• Record what you did and what it cost. The next drought is not a question of if.
