Gce Model Questions Vol1 2021 Agricultural Science Question 10

A mixed farm plans to allocate 10 ha of land for crop production and 5 ha for pasture. The farm intends to raise 80 goats and 30 chickens. The goats require 2.5 kg of concentrate feed per day and 0.5 kg of roughage per day. The chickens require 0.1 kg of concentrate feed per day and 0.02 kg of roughage per day. The farm can produce roughage (grass) on the pasture at a yield of 3 tonnes per hectare per year. Concentrate feed must be purchased at ₦250 per kg. The farm wishes to minimise feed‑purchase cost while meeting nutritional needs. Additionally, the farm aims to generate a net profit of at least ₦2 000 000 per year from the sale of goat meat (average market price ₦2 500 per kg, each goat yields 20 kg of meat) and chicken eggs (average market price ₦150 per dozen, each chicken lays 150 eggs per year).
