Question 6 NECO_MODEL_QUESTIONS_VOL1 • 2019 • AGRICULTURAL_SCIENCE • essay

A smallholder dairy farm keeps 20 lactating Friesian cows. Each cow has an average body weight of 450 kg and produces 22 litres of milk per day. The farm feeds the cows a concentrate mixture containing 20 % crude protein (CP) and a roughage (maize silage) containing 8 % CP. The recommended daily dry‑matter (DM) intake is 3 % of body weight, and the cows require 3.2 g of CP per litre of milk produced.

Question Parts

( a )
Calculate the total dry‑matter intake (in kg) required per cow per day.
( b )
Determine the amount of concentrate (kg) and roughage (kg) each cow should receive daily to meet both the DM and CP requirements. Assume the two feeds together supply the total DM intake.
( c )
If the concentrate costs ₦45,000 per tonne and the roughage costs ₦12,000 per tonne, compute the daily feed cost for the whole herd using the ration derived in part (b).
( d )
Suggest two management interventions that could improve the feed efficiency and milk yield of the herd, explaining the rationale behind each.
