(a) Explain each of the following terms as used in animal nutrition: (i) balanced diet; (ii) maintenance ration; (iii) production ration; (iv) malnutrition....

The essential nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water.

(iv) Malnutrition: Malnutrition is a condition that arises when an animal's diet lacks the essential nutrients required for proper growth and development.

(b) The effects of malnutrition on farm animals include:

(i) Poor growth and development

(ii) Reduced resistance to diseases

(iii) Reduced reproductive performance

(iv) Poor meat or milk quality

(v) Decreased feed efficiency

(vi) Increased susceptibility to environmental stressors

(c) Four nursery practices in the production of tomatoes are:

(i) Seed selection: Use only high-quality seeds from reliable sources to ensure good germination rates and healthy seedlings.

(ii) Seedbed preparation: Prepare the seedbed by loosening the soil, removing weeds and rocks, and adding organic matter to improve soil fertility.

(iii) Watering: Water the seedlings regularly and evenly to prevent water stress and promote healthy growth. (iv) Fertilization: Apply fertilizers, preferably organic, to provide essential nutrients for healthy growth and development.
