(b) A poultry farmer plans to rear broilers in a deep litter house measuring 36m long and 10m wide. If a floor space of 0.36m² per adult chicken is recommended for broiler production, calculate the number of broilers that the farmer can rear.
(c) State five advantages of introducing legumes in a pasture
(a)
(b) The area of the deep litter house is: Area = length x width Area = 36m x 10m Area = 360m² To calculate the number of broilers that can be reared, we need to divide the total area by the recommended floor space per chicken:
Number of broilers = Area / floor space per chicken
Number of broilers = 360m² / 0.36m²
Number of broilers = 1000 broilers
Therefore, the farmer can rear 1000 broilers in the deep litter house.
(c) The advantages of introducing legumes in a pasture include: 1. Nitrogen fixation: Legumes have the ability to fix nitrogen from the air and make it available to other plants in the pasture, which can reduce the need for nitrogen fertilizers.
2. Improved soil fertility: Legumes can improve soil fertility by adding organic matter to the soil and increasing the availability of nutrients.
3. Increased animal productivity: Legumes can provide high-quality forage for grazing animals, which can improve their growth rates and milk production.
4. Weed control: Legumes can compete with weeds for resources, reducing the need for herbicides.
5. Cost-effective: Legumes can be a cost-effective way to improve pasture productivity and reduce the need for expensive inputs like fertilizers and herbicides.
