(a). Mention one use each of specimens A and C.
(b). State four disadvantages of using specimen A in poultry production.
(c) Give four reasons that could be responsible for the choice of specimen B in poultry production.
(d). (i) Give three reasons why specimen C could be used in the construction of poultry house. (ii) Name two farm animals other than poultry for which the housing unit could be constructed with specimen C.
Explanation
(a) Use of specimen A (wooden feed trough).- Supply feed to farm animals. Use of specimen C (chicken wire mesh): - used for fencing. -construction of buildings/pens
(b). Disadvantages of using Specimen A (wooden Teed (rough) in poultry production. -May require frequent maintenance. It may be attacked by termites during storage. Caking of leftover feed may occur/ absorption of moisture. - may harbor pathogens, – difficulty in clearing feeds/ difficult to maintain. – could be contaminated with droppings. - damaged trough may cause injury. – difficult to move around/heavy. - expensive to construct.
(c). Reasons for choosing Specimen B (Plastic cylindrical feeder) in poultry production - Available for all ages of birds. - durable since it cannot be destroyed by termite or water. - readily available/easy to acquire. - ease of maintenance/easy to clean. - low cost of the equipment. reduces feed wastage. - easy to handle/lightweight.- reduces feed contamination
(d)(i).- Reasons for using Specimen C (Chicken wire mesh) in the construction of poultry houses. - Protection against predators, and rodents.- restriction of birds/prevents birds from straying. -improve illumination/lighting. - Cannot be attacked by termites. – for improved ventilation. - protection against intruders. - makes cleaning of cages easier. (ii) Farm animals whose housing unit could be constructed with Specimen C (Chicken wire mesh)
