Explanation
a(i). Explanation of malnutrition in animal husbandry. - Malnutrition is a condition caused by feeding animals a diet that is deficient in essential nutrients, -It is a condition resulting from feeding animals with a diet in excess of essential nutrients. - It could also occur when an animal cannot utilize nutrients in feed given, due to ill health, stress, or other factors, – It could occur when the right quantity of feed is not given to the animal. -Nutrients in the feed are not in the right proportions. (ii). Limiting ingredients that are not included in the diet. -Fibre source c.g. wheat offal, rice bran, maize offal, PKC. - Mineral- vitamin premix. -Common salt/table salt. -Toxin binder/detoxifier. - Vegetable oil/ palm oil- (iii). Importance of limiting ingredients - Fibre - Adds bulk to the feed. - Improves bowel movement. - Improves digestibility. - Reduces incidence of diarrhea in farm animals. -Minerals vitamin premix. -Useful in egg formation. - Improves immunity against disease. – Aids proper absorption of nutrients. – Used in bone formation -Common Salt- Improves palatability. - Promotes activities of enzymes. Supplies sodium and chlorine to the animal. -Increases feed intake. - Improves water intake. - Vegetable Oil/Palm oil -Reduce dustiness of feed. - Improve palatability/acceptability. Improve energy content of the feed.- Improve carotene or vitamin A content of feed. -Toxin Binder/detoxifier - Binds toxin in feed/ - Growth promoter. - Builds immunity. – Traps fungal pathogens.
b.Reasons for keeping farm records by a poultry farmer. - Shows the financial position of the farm. - Enables the farmer to know all the activities carried out on the farm. -For taking management decisions/planning. - For estimating annual tax. – Necessary in obtaining loans. - Helps to detect fraudulent practices on the farm. - Enables the farmer to detect changes in prices. – Used for computing farmer's net worth/farm inventory. - Serves as a requirement to receive awards/levies. -Aids appropriate budgeting. – For purpose of auditing. To assess productivity.
c.Ways of preventing liver fluke from completing its life cycle. - Periodic burning of pasture. - Use of clean, uncontaminated water. -Use of lime to prevent eggs from hatching/liming. Elimination of water snails by introducing docks, -Controls of weeds in ponds and riversides, - Avoid grazing animals on marshy areas. Ensure proper drainage of pasture lands.
