Vitamins, Probiotics and Feed Additives: What Is Worth Paying For?
A sceptical guide to poultry vitamins, electrolytes, probiotics, enzymes, toxin binders and boosters: when each helps, when it wastes money, reading labels.

Key points
Complete commercial feed already contains a vitamin and trace mineral premix, so routine weekly vitamins on healthy birds are mostly money in the drain.
Water vitamins and electrolytes earn their price for short periods of stress: arrival, after handling or vaccination, heat waves and recovery from disease.
Probiotics are live organisms, so check the count, the expiry date and the storage, and never give them alongside an antibiotic or in chlorinated water.
Do not buy any product whose label fails to list the active ingredients, their amounts, a batch number and an expiry date.
Work out the cost per bird of any additive, then ask how many grams of extra weight or how many extra eggs it would need to produce to pay for itself.
Stand at the counter of any agro-vet shop in Ghana and you face a wall of sachets, tubs and bottles: vitamin powders, electrolytes, probiotics, liver tonics, growth boosters, toxin binders, enzymes, herbal mixtures. Each one carries a picture of a heavy broiler or a full crate of eggs. Before you buy any of them, hold on to one fact. A complete feed from a competent mill already contains a vitamin and trace mineral premix designed for the bird it is sold for. Everything on that shelf is therefore an extra, and an extra has to justify itself.
Some do. A few are the difference between a batch that recovers from a bad week and one that does not. Many are bought out of habit or fear, and a farmer running three or four products at once can spend more on sachets than on vaccines. What follows goes through the shelf class by class.
What is already in the bag
Chickens need thirteen vitamins and a handful of trace minerals (zinc, manganese, iron, copper, iodine, selenium) in tiny daily amounts. Maize and soya do not supply enough of them, so feed mills add a premix, usually a few kilos to every tonne. Broiler starter, grower, finisher and layer feeds each have their own premix, and in broiler feed there is commonly a coccidiostat as well.
Two things can leave birds short even so.
Age and storage of the feed. Vitamins break down with heat, light, damp and time. Feed that has sat for months in a hot shop or in a store under a zinc roof has lost part of its vitamin content. Buy feed that is turning over quickly and use it within a few weeks.
Home mixing. If you mix your own ration, the premix is the one ingredient you cannot skip, guess or stretch. Use the right premix for the class of bird, at the rate the manufacturer states, and mix it evenly. Our guide to making your own poultry feed explains how.
True deficiencies have recognisable signs: chicks walking on curled toes (riboflavin), chicks at two to four weeks falling over with twisted heads (vitamin E), soft rubbery bones and beaks (vitamin D3, calcium or phosphorus), slipped hock tendons (manganese). If you see these, the answer is to fix the feed and call a vet, not to pour a general tonic into the water and hope.
Three questions before you pay
What exactly is the problem? "The birds are not growing" is not a diagnosis. Slow growth usually traces to brooding temperature, feed quality, water, stocking density or disease. No sachet fixes a cold brooder.
What is in the product, and how much? A brand name and a picture tell you nothing. You are buying named ingredients in stated amounts.
What does it cost per bird, and what would it have to return? A worked sum comes later in this guide. Most farmers have never done it.
Soluble vitamins and electrolytes
These are powders or liquids for the drinking water, typically vitamins A, D3, E, K, the B group and C, often with electrolytes (salts of sodium and potassium) and sometimes amino acids.
When they earn their price
Their value is tied to one situation: birds that are eating less than normal while needing more than normal. A bird off its feed is also off its vitamins, because the vitamins are in the feed. Water intake usually holds up better than feed intake, so the water is the way in. Sensible uses are short courses of three to five days:
the first days after chicks arrive, particularly after a long road journey;
after beak trimming, weighing, moving house or any heavy handling;
during a heat wave, where electrolytes and vitamin C help birds that are panting and eating little (see managing heat stress in broilers);
during and after an illness, when the vet agrees, to support recovery.
When they are wasted
Healthy birds eating fresh complete feed gain nothing from vitamins every week "to be safe". Water-soluble vitamins beyond what the bird needs leave in the droppings. Fat-soluble ones (A, D3 and E) are stored in the body, and heavy long-term overdosing, which happens when a farmer stacks two or three products that all contain them, can harm birds. Excess vitamin D3 in particular damages the kidneys.
There are practical costs too. Vitamin and sugar solutions feed the slime that grows inside drinkers and pipes, so wash drinkers daily during a course. Mix fresh each morning and discard what is left after a day. Do not put vitamins into water carrying a vaccine unless the vaccine instructions say you may.
Glucose for new chicks
Many Ghanaian farmers give glucose in the first water. A little sugar gives tired chicks quick energy and gets them drinking, and there is no harm in it for the first few hours. After that, plain clean water and feed do the job better. What a chick needs most on arrival is the right floor temperature, and our chick brooding guide sets that out.
Probiotics, prebiotics and organic acids
These three aim at the same target, a stable gut, by different routes.
Probiotics are live, harmless microbes, commonly strains of Lactobacillus, Bacillus, Enterococcus or yeast. The idea is that helpful organisms occupy the gut lining and leave less room and less food for harmful ones. A chick from a hatchery starts life with an almost empty gut, without the microbes it would have picked up from a mother hen, so the case for a probiotic is strongest in the first days of life. It is also reasonable after a course of antibiotics has ended, because antibiotics clear out useful bacteria along with the harmful ones.
The evidence for extra growth in healthy birds on good feed is mixed: some trials show a small gain, others none. So treat a probiotic as gut insurance at specific times, not as a growth product. And because the contents must be alive to work, check these points:
The label should name the organisms and give a count (shown as CFU per gram or per millilitre).
The product must be in date and stored as instructed. A probiotic that has spent months on a sunny shelf is expensive dust.
Chlorinated water kills the organisms. So does an antibiotic given at the same time. Use water without sanitiser while dosing.
Prebiotics are not alive. They are fibres, often made from yeast cell walls, that feed helpful gut bacteria or give harmful bacteria something to stick to instead of the gut wall. They survive heat and storage far better than probiotics, and they go in the feed.
Organic acids (such as citric, lactic, formic and propionic acid, alone or blended) make drinking water mildly acidic. That discourages bacteria in the drinker lines and in the bird's crop. They are useful where water quality is doubtful, which describes many wells and tanks. Follow the label closely and check the result with a cheap pH strip, because water that is too sour puts birds off drinking, and a bird that drinks less eats less. Stop acids, like sanitisers, around any vaccination given in the water. The wider subject of water quality is covered in water for poultry.
Enzymes and toxin binders: tools for the feed mill
These two classes go into feed at mixing, in grams or a few kilos per tonne. They concern you mainly if you mix your own ration or buy from a small local miller.
Enzymes help the bird digest what it otherwise cannot. Phytase releases phosphorus that is locked up in grains and oilseed meals. Other enzymes break down the fibre in wheat bran, rice bran and palm kernel cake. They pay when your ration contains a good share of those fibrous by-products, and they add little to a plain maize and soya ration. An enzyme must suit the ingredient: one made for wheat fibre will not do much for palm kernel cake. Dusting a pinch over a heap and turning it twice with a shovel will not spread grams evenly through a tonne, so mix it first into a few kilos of maize meal, then into the batch.
Toxin binders are fine clays or yeast-based products that hold mould toxins in the gut so that they pass out in the droppings. In Ghana's humid climate, where maize and groundnut products often carry some aflatoxin, a binder in home-mixed feed is reasonable insurance, particularly in the rainy season. Be clear about its limits. Clays bind aflatoxin fairly well but are weak against several other mould toxins that occur in maize. No binder turns visibly mouldy grain into safe feed. Read aflatoxin and mouldy feed for how to prevent the problem at the buying and storage stage, which is where the money is really saved.
Amino acids and calcium are nutrients, not extras
Lysine and methionine are sold as white powders alongside the additives, but they belong in a different category. They are building blocks of protein that maize and soya rations tend to run short of, and a formula that includes them correctly grows birds on less soya and fishmeal. If you mix your own feed, they are among the best value on the shelf. If you buy complete feed, they are already in it.
The same goes for calcium in layers. A hen puts about two grams of calcium into every shell, and coarse limestone or oyster shell in the ration, with a little extra offered in the afternoon for older hens, is a genuine need, not an optional supplement.
Products that deserve suspicion
"Growth boosters" with no ingredient list
Fast growth comes from genetics, feed, temperature and health. A product that promises it without saying what it contains is asking for trust it has not earned. Some turn out to be ordinary vitamins at a premium price. Some contain undeclared drugs.
Antibiotic and vitamin combinations used as routine
Sachets that combine an antibiotic with vitamins are sold widely as a "first week" or "anti-stress" treatment. Giving antibiotics to birds that are not sick breeds resistant bacteria on your farm, leaves residues in meat and eggs if withdrawal periods are ignored, and wipes out the gut bacteria a young chick is trying to establish. Antibiotics are for diagnosed disease, on a vet's advice. We explain why in responsible antibiotic use in poultry.
Extra coccidiostats on top of medicated feed
If your broiler feed already contains a coccidiostat, adding another product "to be sure" can cause harm, and some coccidiostats react badly with certain antibiotics. Ask the feed supplier what the feed contains, and ask a vet before adding any medicine to it.
Liver tonics and herbal mixtures
Liver tonics have little to offer a healthy flock on sound feed. Garlic, ginger, pepper, neem and similar preparations have some laboratory evidence behind them, but results on farms are inconsistent. In moderate amounts they are mostly harmless. The danger is when they are used in place of vaccination or proper diagnosis.
Reading a label in two minutes
Turn the sachet over. A product worth buying shows all of the following:
Active ingredients with amounts per kilo or per litre. "Multivitamins and amino acids" with no figures is not a composition.
Manufacturer's name and address, and a registration number from the regulator where the product type requires one.
Batch number, manufacture date and expiry date. Vitamins and probiotics lose strength with age, so a product with two months left is worth less than one with eighteen.
Directions: how much per litre of water or per kilo of feed, and for how many days.
Withdrawal period for meat and eggs, if it contains any drug.
Storage conditions. If the label says "store below 25 degrees, away from light" and the sachets are faded from sitting in a sunny window, leave them.
Be wary of powders re-packed into plain polythene bags and tied with a knot. You cannot know what is in them, how old they are or how they were kept. Compare products by the amount of each ingredient, not by sachet size. A cheaper sachet with half the vitamin content is not cheaper.

What does it cost per bird?
Here is the sum, with invented prices. Replace them with your own.
Step
Example
Price of one sachet
GH₵ 30
Water one sachet treats (from the label)
200 litres
Water 500 four-week broilers drink in a day
about 100 litres
Sachets per day
half a sachet, GH₵ 15
Five-day course
GH₵ 75
Cost per bird
GH₵ 0.15
Now turn that into production. If live broilers sell at, say, GH₵ 40 a kilo, 15 pesewas is the value of about 4 grams of liveweight. A five-day course given to birds struggling through a heat wave will easily return more than that. The same course given to healthy birds returns nothing.
The picture changes when products are run continuously. Suppose a farmer keeps three products in the water for the whole six weeks, averaging GH₵ 10 a day each. That is GH₵ 1,260 on the batch, or about GH₵ 2.50 a bird, which on these example prices is more than 60 grams of liveweight per bird that the additives must produce just to break even. Put your own figure into the poultry profit calculator as an extra cost per bird and see what it does to the margin.

Where the first cedi should go
If the budget is tight, spend in this order: sound chicks, fresh feed of the right type, clean water, correct brooding temperature, the vaccination programme your vet sets, and a clean house. Those six decide most of the result. Additives work at the edges, and only once the basics are in place.
It helps to know what your chicks have already received. Chicks from Halaal Farms Ghana are vaccinated at the hatchery before they leave, and you should ask what a particular batch has had so that you do not pay to repeat it or leave a gap. Advice is free before and after an order. If birds are slow or dull and you are tempted by a booster, call 024 915 1503 first or send us a message through the order form. The cause is often something a sachet cannot reach, and you can check current chick prices on the day-old chick price list while you plan the next batch.
Questions farmers ask
Should I give my broilers vitamins every week?
On a good complete feed from a reputable mill, no. The feed already carries the vitamins the bird needs, and healthy birds pass the extra out in their droppings. Keep a soluble vitamin and electrolyte product for short courses of three to five days around real stress: arrival of chicks, heat waves, heavy handling, or recovery after an illness when birds have been eating poorly.
Do probiotics replace antibiotics in poultry?
No. A probiotic helps a healthy gut stay stable and may reduce the chance of some gut upsets, which can lower the need for treatment over time. It does not cure a sick flock. When birds are ill, a vet needs to identify the disease and decide the treatment. Probiotics are most useful in the first days of a chick's life and after a course of antibiotics has finished.
Can a toxin binder make mouldy feed safe for chickens?
It cannot. Clay binders hold on to aflatoxin reasonably well, but they do little against several other mould toxins commonly found in maize, and no binder restores the nutrients that mould has destroyed. A binder is insurance against low-level contamination you cannot see. Feed or maize that looks, smells or feels mouldy should be kept away from poultry altogether.
Is glucose good for day-old chicks when they arrive?
A little glucose or sugar in the first drinking water gives tired chicks quick energy after a long journey and encourages them to drink. Use it only for the first few hours, then change to plain clean water and feed. Sweetened water left in warm drinkers grows bacteria quickly, and glucose is no substitute for correct brooder temperature, which is what chicks need most on arrival.
