Poultry Feed Formulation Basics for Ghana: Ingredients and Mixes

What feed formulation actually means

Feed formulation is the job of choosing ingredients and their proportions so that a bird receives what it needs, in the right amounts, at the right age. A chick does not need the same feed as a laying hen, and a broiler finishing for market needs something different again. Formulation balances four things: energy to fuel growth and egg production, protein and amino acids to build muscle and feathers, minerals to build bone and shell, and vitamins to keep the immune system and metabolism working.

Many farmers in Ghana buy ready-mixed feed from a shop and never think about formulation. That is a perfectly sound choice for a small flock. Understanding the basics still matters, for three reasons. You can judge whether a bag is good value. You can spot when a feed is poorly mixed or has gone off. And if you decide to mix your own, you will not be led by a salesman's claim or a formula copied from a forum without knowing what it contains.

Formulation also explains why feed matters so much to the business. Feed is usually the largest recurring cost on a poultry farm, so small errors in the mix or in feeding practice add up quickly. A ration that is a little low in protein can slow growth for weeks. A layer ration that is short of calcium can cut shell quality, and the lost eggs cost more than the feed you tried to save.

The five ingredient groups in a basic mix

Most practical rations are built from five groups of ingredients. Each group does a specific job, and most feed problems come from one group being too high or too low.

• Energy sources. Ground maize is the most common in Ghana. It provides starch and oil that the bird turns into energy. Wheat bran, rice bran and palm oil also add energy, while cassava chips are energy-rich but very low in protein and should be used with care.
• Protein sources. Soybean meal is the main protein in most mixes. Fish meal adds high-quality protein and amino acids in small amounts. Groundnut cake, cottonseed cake and palm kernel cake can be used, but their protein quality and fibre content vary, so their share must be limited.
• Minerals. Limestone or oyster shell supplies calcium. Dicalcium phosphate supplies phosphorus. Salt supplies sodium and chloride. Birds need all three, and a shortage or imbalance shows up quickly in bone and egg quality.
• Amino acid supplements. Methionine and lysine are added in small quantities to correct the amino acid balance when the main protein sources do not provide enough of them.
• Premix. A vitamin and trace mineral pack, bought from a reliable supplier and used at the label rate. It is the smallest part of the mix by weight but essential for health and growth.

Some farmers add a coccidiostat or other medicated additive to starter feed. That decision belongs to your vet, and withdrawal times on the label must be respected. Do not add medicines on your own guess.

Protein and energy targets by stage

Targets depend on the stage of life and the bird's purpose. The figures below are typical ranges used across the tropics. They are a starting point for a discussion with your feed supplier or nutritionist, not a formula to be copied without checking your own ingredients.

Notice that broilers need the most protein early and the most energy late. Feeding a starter ration for the whole cycle is a common mistake. The birds grow more slowly on the lower protein later, and you pay for more feed to reach the same weight. For layers, the calcium target matters as much as the protein figure, because a hen that does not get enough calcium will lay eggs with thin or soft shells.

If you are rearing for a particular market, read our notes on the broiler feeding schedule week by week and on layer feeding, which go deeper into the timing of each change.

Local ingredients and what each one brings

Ghana has a good range of feed ingredients, but quality varies a great deal between suppliers and between batches. The same name on a sack can hide very different protein levels, fibre contents and levels of moulds. Buy from a source you trust, ask for the protein figure, and look at the material before you pay.

Ground maize is the backbone of most rations because it is widely available and high in energy. Buy it dry, and check for mould, insect damage and a sour or musty smell. Soybean meal is the main protein source, and a good soybean meal is light brown, not burnt and not lumpy. Wheat bran is useful for bulk and fibre in layer mashes, but it is high in phosphorus that the bird cannot fully use, which is one reason the phosphorus source must be considered carefully.

Fish meal is valuable because it brings amino acids that plant proteins lack in useful amounts. Its quality depends on how it was processed and dried. A fish meal that smells of ammonia or has been stored in damp conditions should not go into the mix. Palm kernel cake is cheaper and useful in small amounts, but it is high in fibre, so it suits some stages better than others.

Rice bran and cassava products can reduce cost, but they change the mix. Our team at the hatchery in Kasoa sees many farmers try a cheaper ingredient, so the lesson is worth stating plainly. Cassava is low in protein, so any ration that uses more of it must replace some of the protein elsewhere. Work out the new protein before you change the mix.

A simple example mix, worked out in full

The example below is a teaching mix for a broiler grower in the 3 to 4 week range. It is not a formula to copy. Ingredient qualities differ, and your birds' response will tell you more than any table. Use it to see how the parts fit together and how to check a mix before you feed it.

Mix the premix, methionine and salt with a small amount of maize first, then blend that into the larger batch. Trace ingredients mixed straight into the full batch often end up unevenly spread, and an uneven mix means some birds get too much and others too little.

Checking the protein of any mix yourself

You can estimate the crude protein of a mix with a simple calculation. For each ingredient, multiply its share in the mix by its protein content, then add the results. Use the protein figure on the supplier's bag or from a laboratory test. The result is an estimate, but it is close enough to catch a serious mistake before the birds eat it.

The example mix comes out at about 21 per cent crude protein, which sits within the range for a broiler grower. If the total had come out at 17 per cent, you would know straight away that the soybean meal was too low or that a weaker protein had been substituted. The calculation is simple, but it is powerful, because it lets you test a supplier's claim or a new recipe before a single bag is opened for the birds.

Remember that the figures are only as good as the values you enter. Protein content varies between batches, so a laboratory analysis of your actual ingredients remains the only reliable check. Ask your nutritionist or a laboratory that handles feed samples to test your main ingredients a few times a year.

Calcium and phosphorus for laying hens

Layers need far more calcium than broilers, and the form of calcium matters as much as the amount. Limestone is fine ground calcium and is absorbed quickly. Oyster shell is coarser and dissolves more slowly, so it stays in the gizzard and gives a steady supply through the night, when the shell is formed. Many farmers offer a mash for daily use and a separate bowl of coarse oyster shell so the hen can take what she needs.

Phosphorus is the partner to calcium. Dicalcium phosphate supplies it in a form the bird can use well. The balance between calcium and phosphorus matters for bone strength, and an imbalance can cause leg weakness and poor shell quality even when the total calcium looks sufficient. Keep the phosphorus and calcium figures on your formula sheet and check them every time the mix changes.

Watch the hens as well as the feed. Soft-shelled or thin-shelled eggs, eggs with rough or chalky shells, and hens that stand with a hunched back or reluctance to walk can all point to a calcium or phosphorus problem. Other causes exist too, including disease and stress, so if the problem persists, take the flock to your vet and do not rely on the feed alone. Our note on soft-shelled eggs covers the common causes in more detail.

Storage, mould and feed quality

Feed loses quality from the moment it is ground and mixed. Heat, humidity and time are the three enemies. In Ghana's rainy season, damp floors and leaking roofs are the usual cause of mould in feed stores, and a mouldy ingredient can carry toxins that harm birds, sometimes without any obvious sign at first. Mouldy maize is one of the most serious feed risks on Ghanaian farms. If in doubt, throw it out.

• Store bags on pallets, away from walls and off the floor.
• Keep stock rotated so the oldest bags are used first.
• Keep the store cool, dry, dark and free from rats and insects.
• Do not mix wet ingredients into a dry batch.
• Keep a small sample of each batch in a sealed bag, labelled with the date.

During harmattan the air is dry, but dust is heavy, and dusty feed wastes ingredients and harms birds' airways. Store and mix in a covered area, and sweep the store regularly. A tidy feed store is one of the cheapest ways to protect your investment.

Cautions that save birds and money

Formulation is not a one-time job. Several mistakes repeat across farms, and each one can cost far more than a bag of feed.

1. Copying an online formula without checking the ingredients. A recipe from another country uses ingredients with different protein and energy values. Check your own ingredients before using it.
2. Changing the ration suddenly. Introduce a new mix over three to five days, mixing it in gradually. Sudden changes upset digestion and cut intake.
3. Leaving out salt or mixing it unevenly. Too little salt slows growth and too much can poison birds, especially when water is short.
4. Ignoring intake. If the birds eat less, the ration may be wrong, or the birds may be sick. Record feed used each day so you can spot the change early.
5. Feeding medicated feed beyond the label. Follow the withdrawal times and your vet's advice on any additive.

Feed is also where many farms can save money, but the saving should never come from the protein or the minerals. Cutting protein to save cost usually costs more in growth and eggs than it saves in feed. Cutting the premix to save cost is a false economy. If your birds are slow despite a sound ration, our notes on getting heavy broilers cover the other factors that hold growth back, and our frequently asked questions answer the common queries we receive about rearing.

Costing a mix and checking that it pays

To cost your own mix, multiply each ingredient's price per kilogram by its share in the mix, then add the results. This gives the cost per kilogram of finished feed. Use your own local prices, because they change with the season and with the supplier. The method is the same whatever the prices are.

The cost per kilogram is only half the story. What matters is the cost per kilogram of weight gained or the cost per egg produced. A cheaper feed that the birds do not convert well can cost more per bird than a dearer feed with better conversion. Record feed used and bird weights, then divide feed used by weight gained to get the feed conversion ratio. Compare that figure from one batch to the next.

Our day-old chicks are priced from our current price list, and feed is usually the biggest cost after the chicks. Planning the feed programme before the chicks arrive lets you compare real costs against real results, rather than guessing. If you are new to the numbers, our poultry farm budget guide shows how the feed line fits into the total.

A monthly feed check

Once a month, go through the feed programme with the same care you give the birds. The checklist below takes an hour and catches most problems before they cost birds.

• Check the protein and energy of the current mix against the target for each stage.
• Confirm that calcium and phosphorus figures match the layer or grower formula.
• Inspect the store for mould, insects, damp and leaks.
• Compare feed used with birds alive and weights gained over the month.
• Test or sample any new ingredient or supplier before using it in bulk.
• Confirm that premix, methionine and salt are stored and measured correctly.
• Ask your vet or nutritionist to review the formula if birds are slow or eggs are poor.
