WHAT IS DIET
DIET: Definition; A diet is defined as the amount of feeds regularly given to or consumed by animal. It is formulated to meet specific metabolic or physiological functions such as Growth, lactation, maintenance of pregnancy, reproduction, egg-laying and so on.
WHAT IS RATION
RATION: Ration is the total supply of feed given to an animal in a 24-hour period. In other words, ration is the amount of food taken by animal daily.
WHAT IS BALANCE RATION
BALANCE RATION: In animal feeds and livestock rations, a balanced ration is the food containing all essential nutrients in the correct quantity and in adequate proportion for feeding animals daily.
Components of balanced ration include carbohydrate, protein, fats and oil, minerals, vitamins and water. All this must be taken at the right proportion by animals for normal Growth, lactation, reproduction and other body activities.
FACTORS NORMALLY CONSIDERED WHEN DECIDING THE TYPES OF RATION TO FEED AN ANIMAL
- The purpose for which the animal is being kept: If an animal is to be kept for the purpose for production, such animal will require more feed while those not for production will require less feed.
- The class of animal: Animals belong to different classes and as such, their feed requirement will also vary.
- Age of the animal: Feeds are given to farm animals based on their ages, for example in poultry, the chicks (0 to 6 weeks) requires more nutrition feed (20% crude protein) than growers (6 – 18 weeks) which requires about 14% crude protein.
- Animals condition of health: The animals that are healthy tend to eat more feed while sick once consume less.
- Management System: The management system also determine the types of feed given to farm animals. Quality feed are usually given to farm animals on intensive system of management while animals on extensive system fend for themselves.
- Physiological state of the animals: Pregnant and lactating animals tend to consume more feeds than animals that are not in this conditions.

TYPES OF RATION
There are two types of ration: These are;
- MAINTENANCE RATION
- PRODUCTION RATION
1. Maintenance ration: This is the types of ration given to farm animals just to maintain normal functioning of the body system. In other words, maintenance ration supplies enough nutrients just to enable the animal carry on the normal body activities without losing or gaining weight. The Ration enables the animal to maintain it’s body weight but, it cannot be used for production purposes. Examples of maintenance ration include the ration given to ruminant animals like straw, hay, during dry season. Maintenance ration can be supplied to breeding animals when they are not breeding. It can also be supplied to dry or non lactating animals when they are not lactating.
2. Production Ration: This is the types of ration is given to farm animals to enable them produce. In other words, production ration supplies nutrients above what it is required for maintenance in order to make the animal capable of high production which can be in form of milk, meats, egg and Growth, etc.
Categories of farm animals that require production rations includes:
- Lactating Animals: For milk production.
- Weaning Animals: For increase production.
- Pregnant animals: For maintenance of the foetus.
- Fattening Animals: For extra addition of more meat or flesh.
- Broilers: For rapid growth.
- Layers: For egg production.
- Steaming up for flushing: For animal before mating to produce more ova/ovum.
RATION FORMULATION: Ration formulation involves the careful combination of all the food nutrient in such a way as to meet the nutritional requirement for a particular animal. When formulating ration for farm animals the following principles should be considered.
1. The physiological state of the animals, whether for pregnant, dry or lactating or young animals.
2. The availability of the feedstuff.
3. The age of the animal.
4. The composition of the nutrients.
5. Palatability of the feed.
7. The cost of the feedsstuff.
Careful combination of protein sources, (e.g, fishmeal, groundnut cake) FAT SOURCES (e g, palm kernel cake, oils) VITAMINS, MINERAL SOURCES (e.g, bone meal, oyster shell) CARBOHYDRATES SOURCES (e.g, Maize, guinea corn) will provide all the food nutrients to prepare a balanced diet or ration.
To prepare a Ration for layers, the following ingredients, for example are required.
1. Maize meal (carbohydrates) = 65%
2. Groundnut cake ( protein) = 20%
3. Fish meal (protein)= 5%
4. Palm oil (oil) ,= 4%
5. Bone meal (mineral) 5%
6. Mineral salt ( mineral) 0.5%
7. Vitamins supplements (vitamins) 0.5%
Total = 100%.
Revision Questions
- What is balance ration?
- Distinguish between maintenance and production ration.
- Write short notes on the following: maintenance ration, production ration and balance reaction.
- What is ration formulation?
- If birds at the point of lay were fed a ration (feed) containing: maize meal – 65%, groundnut cake – 25%, fish meal – 5% and brewer’s grain – 5% name the other feed ingredients that are essential which are not listed. State importance of the ingredients you have listed.
