Worked Solution & Example Answer:The picture below indicates a proper housing structure for broiler production - NSC Agricultural Sciences - Question 3 - 2016 - Paper 1
Step 1
3.1.1 Name TWO requirements of the roofing material in order to regulate temperature in the above housing structure.
Answer
The roofing material for broiler housing should:
- Have a reflective surface on the outside to reduce heat absorption from solar radiation.
- Help to minimize heat conduction to maintain an optimal internal temperature.
Step 2
3.1.2 Besides roofing material, suggest TWO other ways in which temperature can be regulated for this broiler production enterprise.
Answer
Two other methods to regulate temperature in broiler production are:
- Installing heat lamps or heaters in cold weather to provide additional warmth.
- Using ventilation systems to promote airflow and control humidity levels.
Step 3
3.1.3 Name the best orientation of the broiler house in South Africa and give a reason for the answer.
Answer
The best orientation for a broiler house in South Africa is East. This orientation helps reduce the impact of direct sunlight on the house, thereby maintaining a cooler internal environment.
Step 4
3.1.4 Give TWO reasons for the use of part A in the above housing structure.
Answer
Two purposes for the part labeled A in the broiler housing structure are:
- To allow sufficient ventilation and airflow, which is essential for maintaining a healthy environment for the birds.
- To allow diffused sunlight, which can provide natural warmth without causing overheating.
