Introduction To Animal Nutrition

Muhtasari

Two goats graze the same patch of ground outside Kaduna. One carries a glossy coat and a fat kid at foot; the other is dull, thin and slow to breed. Same species, same paddock, same water trough. The difference almost always comes down to one thing: nutrition. Not how much the animal ate, but whether what it ate actually supplied everything a living body needs to build muscle, grow bone, fight infection and produce milk or eggs.

This lesson opens the Animal Nutrition section of the syllabus and lays its foundation. You will meet the six classes of nutrients every farm animal requires, learn precisely what each one does in the body, understand what makes a ration balanced rather than merely filling, and see what goes wrong, organ by organ, when a nutrient is missing. Every later topic on feeds, rationing, storage and record keeping assumes you already have this map firmly in your head.

Malengo

  1. Define animal nutrition
  2. State the classes of nutrients required by farm animals
  3. Explain the functions of nutrients in the body of a farm animal
  4. State the importance of a balanced ration
  5. Explain the effect of nutrient deficiency on farm animals

Maelezo ya Somo

A poultry keeper in Ogbomoso fed her layers only leftover maize bran. Within weeks her hens laid thin-shelled eggs and several developed bowed legs. The birds were not starving; they lacked the calcium their shell glands needed daily. A candidate who knows the six nutrient classes would spot that fault at once, and so will you.
