Feed Additives for Poultry in Ghana: What Each One Does

What counts as an additive, and what does not

Ask five poultry farmers what a feed additive is and you will get five answers. Some mean vitamins and minerals. Some mean anything that comes in a sachet. Some mean the medicine the vet told them to put in the feed for a week. For this article we mean the group that sits outside the main nutrients: energy, protein, calcium and the basic minerals and vitamins that the formula already covers. Those are the ingredients. Additives are the extras that change how the feed is stored, digested or used by the bird.

The split matters because the rules and the evidence differ for each group. Enzymes and probiotics are protein-based or living products with their own strengths and weaknesses. Antioxidants and mould inhibitors are chemicals that protect the feed itself. Coccidiostats are medicines and belong in a separate class. We cover vitamins and minerals in our premix article, and enzymes and probiotics have their own pages, so this one stays with the wider group and how to judge it.

The main types you will see on a feed bag

Most bags sold in Ghana list their additives in small print, often as one line under the ingredient list. The table sorts the common types by what they do, when they earn their cost, and the question to ask before you buy.

For the enzymes and the binders in that table, our enzymes article and toxin binder article go deeper than this overview.

Two things stand out. Almost every additive has a narrow job, and a product that claims to do everything is usually doing very little. The cheapest additive on the shelf is seldom the one that makes a difference. The ones that work tend to be the ones the miller formulated around a specific problem, and the miller should be able to tell you what that problem was.

Why fat goes off, and the antioxidant question

If you have ever opened a bag of mash and caught a smell like old frying oil, you have met oxidised fat. The oils and fish products that give feed its energy go rancid when they react with air, and heat and humidity speed that up. Rancid fat is less digestible, birds eat less of it, and it breaks down some of the vitamins in the same mix. The first sign on the farm is often not the smell at all. It is a dip in intake that nobody can explain.

Antioxidants slow that reaction. They matter most in feeds with added oil, and in feeds with fish meal, which carries a lot of unsaturated fat. They matter least in a plain maize and soya mash that has been stored for a few days. If your miller uses one, ask which antioxidant and at what level. Vitamin E is also an antioxidant, and it may already be in your premix, so check the formula before you add a second one.

An antioxidant does not make an old bag fresh. It slows the clock. The bags that go bad fastest are the ones kept in a hot store for months, and no additive buys that time back. Buy in quantities you will use within a few weeks, keep the bags off the floor and out of the sun, and treat a rancid smell as a reason to stop feeding that bag.

Mould inhibitors: useful in the rains, not a cure

Mould inhibitors, often propionic acid or a blend of organic acids, go into feed that is damp when it is mixed or that will sit in a store through the wet months. They slow the growth of the moulds that make mycotoxins. Used properly they buy you time, which is useful in the rainy season when every bag seems to come in soft.

What they cannot do is remove toxins that are already in the feed. A bag colonised by mould before the inhibitor went in is still a bag to test. Some farmers treat an inhibitor as permission to store feed less carefully, and that is the wrong lesson. A sprayed bag left in a wet corner is still a wet bag, and the inhibitor spends the whole time working against the damp.

In our experience, the farms that struggle are rarely the ones with the cheapest feed. They are the ones whose feed store has a leak, a gap at the wall, or a pile of bags against the back door. A preservative helps a good store. It does not rescue a poor one, and our storage article covers the store side in detail.

Acidifiers, and why young chicks get the most attention

Organic acids such as citric, formic, lactic and propionic acid are added to feed or water to lower the pH of the gut. The idea is that a more acid gut favours the good bacteria and makes life harder for the bad ones. Young chicks are the usual test case, because their gut is still settling and because the first two weeks are when many farms lose birds to infections picked up in a dirty brooder.

The trials are mixed. Some show better weight gain or fewer losses in young birds, especially on feeds with weaker ingredients. Others show little difference when the house is clean and the feed is good. The sensible reading is that acidifiers work best as a backup, not a daily habit. If your brooding is clean, the feed is dry and the water is fresh, you will struggle to measure what an acidifier adds.

Probiotics follow a similar logic and get their own treatment in our probiotics article. Use acids with care. They corrode metal drinkers and stain plastic, and a strong acid in the water can make birds drink less. If you add one, follow the dilution on the label and clean the lines regularly so the acid is not building up deposits.

Flavours and herbs: a good trick, a weak promise

Flavours do one job well. A bird that has eaten one feed for three weeks may refuse a new one for a day or two, and that dip in intake costs weight. A flavour can get the bird eating again quickly. Use it for the change, then drop it once the birds have settled on the new feed. Keeping it in for the whole cycle is a cost with no clear return.

Herbal and plant extracts are another matter. Garlic, oregano, neem and a long list of trade names are sold on the promise of gut health and natural immunity. Some have interesting lab results. The trouble is that a laboratory is not a farm. Results change with the dose, the bird, the age and the climate, and sellers rarely show the trial with its controls. Ask for it. If it is not there, treat the claim as a hope.

We are not against plants in feed. Moringa leaf and other local greens can earn a place in a ration as ingredients you measure and count, which is a different thing from an additive you hope about. What we are against is paying a premium for a sachet that promises more than the feed can deliver.

The break-even sum before you buy

Most farmers buy an additive on feel. The bird looks better, the seller is convincing, and the bag is on the shelf. Before you spend, do the sum. It takes five minutes, and it shows whether the product has to save money, add weight or do both to be worth the cost.

Here is a simple example. Say an additive costs GH₵ 9 per 50 kg bag, and you will use 40 bags over a broiler cycle. The additive costs GH₵ 360 across that cycle. For a flock of 500 birds, that is GH₵ 0.72 a bird. The birds have to finish at least that much better, through extra weight or less feed per kilo of gain, or the product has lost you money. Those figures are made up for the sum and will not match your costs, but the method holds.

Now set that against the chick. A Ross 308 chick from our hatchery starts at GH₵ 20, confirmed in writing before payment. An additive worth GH₵ 0.72 a bird is a small slice of what that bird costs you, but it is still a cost you should be able to point to. If you cannot show how it earns back that amount, you are guessing with money you have already spent.

How to test a claim on your own birds

A trial does not need a laboratory. It needs two pens, the same birds, the same house and a patient farmer. Follow these steps and you will learn more in one cycle than any sales talk can tell you.

1. Split one batch of chicks of the same age and breed into two pens of equal size, in the same house if you can.
2. Feed both pens the same base feed. Put the additive into one pen only, at the rate on the label, and mix it in properly.
3. Weigh a sample of twenty birds from each pen every week. Weigh the same sample each time, not whichever birds come to hand.
4. Record the feed you put out for each pen and the feed left over. That gives you feed used per pen, which is the number that tells you the cost.
5. Count deaths and culls for each pen separately, and write down the cause where you know it.
6. Run the trial for a full phase, such as the starter or the grower, not three days. Compare the results at the end and decide.

Expect a small difference, or none. A good additive on a good farm usually makes a modest improvement, which is still worth knowing. If the difference is large, check that the two pens really were treated the same before you celebrate.

What a good supplier can tell you

A seller who knows his product will answer these questions without a long pause. A seller who does not will change the subject to how well the last farm did.

Ask for the active ingredient, not only the brand name. Ask for the level in the feed, written on the bag or the data sheet. Ask which birds it was tested on, at what age and in what climate, because a trial in a cool temperate shed tells you little about a hot house in Kasoa in April. Ask for the results in writing. And ask what happens to the product when the feed is pelleted, because heat is the first thing that breaks many additives down.

If the answers come back vague, you have learned something. A product with a clear data sheet is a product you can test. A product wrapped in marketing and nothing else is one you cannot test, and that is the one to leave on the shelf. You can take the same questions to your breed choice too, since the right feed and the right bird go together.

Where we stand as a hatchery

We hatch chicks. We do not claim to know your feed better than your miller, and we will not tell you which additive to buy. What we do see is what most farms ask about in the first few months, and the honest answer is that feed and housing come up more often than anything else. Farmers reach for an additive when the real problem is a damp house, dirty drinkers, or chicks that arrived after a long journey without a proper rest.

The hatchery vaccines go in before a chick leaves us, and the batch record lists each one. Those vaccines are the foundation of the health plan, and no feed additive replaces them. Follow your vet's programme for the rest, and treat additives as the last tuning, not the first fix.

If you are planning a flock now, start with the basics on our broiler chick page or the layer chick page, then come back to feed once the house is working. Ross 308 broiler chicks start from GH₵ 20 and Hy-Line Brown layers from GH₵ 23. You can place an order through the order form, or send us a WhatsApp on +233 24 915 1503 if you want to talk it through first.

A checklist before you buy any additive

Run through this list every time someone offers you a bag, a tub or a sachet. If you cannot tick most of it, put the money into the water line or the ventilation instead.

• I know which problem I am solving, and I can name it in one sentence.
• I have the active ingredient and the level in the feed, in writing.
• I know the test the product passed, on what birds, and where.
• I have worked out the break-even per bird using my own feed price.
• I have a control pen, or I accept that I will not know whether it works.
• I have asked whether the product survives pelleting, if my feed is pelleted.
• I have checked the withdrawal time, if the product is a medicine.
• I have a dry, cool place to store it, away from the feed bins and the sun.
