DEFINITION OF FEED
Feed refers to the food given to animals. They containnutrientelement either alone or in combination with other substances which supports the healthy growth and development of livestock.
TYPES OF FEED
Animal feeds can be classified into four main groups according to the digestibility, quantity of fibre, quantity required and moisture in the feed. The four groups of feeds are;
1. Concentrates: They are fee with a low proportion of fibre and water content. They are easily digested by farm animals. Concentrates can be further be subdivided into two groups: Those containing a high proportion of carbohydrates are called carbohydrate concentrates/basal feed/energy feede.g maize, guinea corn, cassava e.t.c while those with a high proportion of proteins are called protein concentrates e.g beans, peas, cotton seed, sunflower seeds and heads, groundnuts, palm kernel and animal products such as meat, blood meal, bone meal, fishmeal and milk.
2. Roughages: Roughages are very low in protein and carbohydrate but high in fibre. They are not easily digested by animals, therefore are fed together with concentrate foods for young animals and those kept for milk and meat production. Examples are hay, groundnut hulls, straw, bean pods and maize stover.
3. Succulents: These have high water content. They are easy to digest. Examples are freshly cut/lush grass and legume plants (soilage), pumpkin, silage, melons and most green crops.
4. Supplements (minerals and vitamis): they are required in small quantities, low in energy, protein and fibre but high in vitamins and minerals. They aid digestion and increase animals resistance to diseases. They are available in basal and protein concentrate feeds. Other sources are bone meal, oyster shell, salt licks etc.
EVALUATION
1. What do you understand as animal feed?
2. List types of animal feed.
FEEDING TOOLS AND EQUIPMENT FOR FARM ANIMALS
Common animal feeding equipment includes:
1. Hay racks: They are used for feeding animals with hay and other forages
2. Feed troughs or bunks: These are used for feeding grain and silage. Troughs for feeding cattle are usually stationary and located on a well-drained site preferably on concrete or hard surfaces.
3. Self-feeders: These are mainly used for fattening cattle. Self-feeders may be stationary or portable.
4. Watering facilities: Farm animals cannot survive for a long time without water. Mature cattle can consume an average of 12 litres of water per head daily depending on the size of the animals, season and the type of feedconsumed. Water troughs, wells, springs, streams, or lakes are the main sources of water supply for cattle. Water troughs and tanks should be of adequate size when used.
NOTE: Farm animals should be provided with suitable shade while feeding particularly during the dry season to reduce heat burden.
EVALUATION
1. Define animal feeds.
2. List three farm animals feeding tools and equipment.
GENERAL EVALUATION/REVISION QUESTIONS
