(a) Most common source of energy in livestock rations

Specimen G (ground sorghum, guinea corn) is the most common source of energy in livestock rations. Its endosperm is rich in starch (carbohydrate), which is readily digested and supplies abundant metabolisable energy.

(b) Ingredient in specimen I with a laxative effect

Wheat offal (wheat bran). Because of its high fibre content it has a laxative effect on farm animals. (Rice bran, maize offal and brewers' dried grains act in the same way.)

(c) Three feed ingredients in specimen I essential for bone and teeth formation

• Bone meal.
• Oyster shell.
• Fish meal.

These supply calcium and phosphorus, the minerals needed for the formation of strong bones and teeth. (Dicalcium phosphate and periwinkle shell are also acceptable.)

(d) Four types of specimen I and the class of poultry to which each is fed

(e) Four farm animals that feed largely on specimen J (forage grass)

• Cattle
• Sheep
• Goat
• Rabbit

(f) Four plant protein sources used in livestock feeds

1. Groundnut cake
2. Soya bean meal
3. Cotton seed cake
4. Palm kernel cake
