Formulation And Preparation Of Animal Feeds
Muhtasari
A poultry farmer in Ogbomoso can buy a bag of finished broiler feed, or she can buy maize and groundnut cake separately and mix her own. The second option is far cheaper, but only if she gets the mixture right. Too little protein and her birds grow slowly; too much and she has wasted money on an ingredient she did not need. Feed formulation is the skill that answers the question precisely: how much of each ingredient, in what proportion, to hit a target nutrient level.
In this lesson you will learn the factors every formulator weighs before choosing ingredients, then master the Pearson square method, the simple diagonal-subtraction technique WAEC expects you to use for a two-ingredient ration. You will work through several fully calculated examples, then move from the recipe to the mixing shed: the methods and equipment used to turn a formulated ration into feed an animal can actually eat.
Malengo
- Define feed formulation
- State the factors considered when formulating a ration
- Compute a simple balanced ration using the Pearson square method
- Explain the methods of feed preparation
- State the equipment used in feed preparation

Swali 1 Ripoti
(a) Explain the term malnutrition in farm animals.
(b) Distinguish between maintenance ration and production ration.
Maelezo ya Majibu
(a) Meaning of malnutrition in farm animals
Malnutrition is a disorder that results when farm animals are fed with feed that is deficient in one or more essential nutrients, or in which the nutrients are supplied in the wrong proportion (either in excess or in short supply). It leads to poor health, retarded growth, low productivity, deficiency diseases and, in severe cases, death.
(b) Distinction between maintenance ration and production ration
| Maintenance ration | Production ration |
|---|---|
| Amount of feed given to keep an animal alive and in good health. | Feed given in addition to the maintenance ration. |
| Supports only basic body functions such as respiration, circulation and body temperature. | Supports production such as growth, milk, eggs, meat, wool, work or reproduction. |
| Causes neither gain nor loss in body weight. | Enables the animal to gain weight and yield products. |
