Worked Solution & Example Answer:The table below shows the temperature requirements of broiler chickens at various ages - NSC Agricultural Sciences - Question 3 - 2020 - Paper 1
Step 1
Draw a bar graph showing the temperature requirements of broiler chickens at various ages.
Answer
To create the bar graph, follow these steps:
- Label the Axes: The x-axis will represent 'Age in weeks' with values from 1 to 7, while the y-axis will represent the 'Temperature requirements (°C)' ranging from 0 to 40.
- Plot Data Points: Plot the corresponding temperatures for each week as follows:
- Week 1: 35°C
- Week 2: 30°C
- Week 3: 25°C
- Week 4: 22°C
- Week 5: 20°C
- Week 6: 20°C
- Week 7: 20°C
- Draw Bars: Construct vertical bars for each week corresponding to the plotted temperatures. Ensure that the bars are accurately proportioned to reflect the temperature data.
- Title the Graph: Provide a suitable title such as 'Temperature Requirements of Broiler Chickens at Various Ages'.
- Check Details: Finally, ensure that all labels are clear and the graph is neat and easy to read.
Step 2
Deduce the trend in temperature requirements of broiler chickens.
Answer
The trend in temperature requirements indicates that as the age of the broiler chickens increases, the temperature requirement decreases. Specifically:
- Week 1 requires the highest temperature at 35°C.
- As the weeks progress to Week 3, the temperature drops to 25°C.
- From Week 4 onward, the temperature stabilizes at 20°C, suggesting that older chickens require less heat. This trend depicts how younger chickens need more warmth for optimal growth and development.
Step 3
Name the equipment that can be used to maintain the temperature in a broiler house.
Answer
Equipment that can be used to maintain the temperature in a broiler house includes:
- Heaters: These provide direct heat to maintain warmth, especially for younger chicks.
- Fans: Used to circulate air and manage heat levels, preventing overheating.
- Infrared lamps: Often used to provide heat to specific areas or to supplement warmth during cooler temperatures.
- Curtains and Insulators: These help in conserving heat within the broiler house by managing external airflow, thus maintaining a stable environment.
