Question 6 NECO • 2024 • AGRICULTURAL_SCIENCE • essay

A dairy farmer keeps 40 lactating cows. Each cow currently produces an average of 20 litres of milk per day on a total mixed ration (TMR) that supplies 14 % crude protein (CP) and costs ₦120 per kilogram. The farmer wishes to increase total milk production by 15 % over the next year by improving the cows' nutrition. He plans to introduce a new TMR that supplies 18 % CP and costs ₦150 per kilogram. Research indicates that for each 1 % increase in dietary CP above 14 %, milk yield rises by 0.8 L per cow per day, but the response plateaus after a 2 % increase in CP. Each cow consumes 25 kg of ration per day. The market price of milk is ₦180 per litre. Answer the following questions:

Question Parts

( a )
Calculate the expected new average daily milk yield per cow after the diet change.
( b )
Determine the additional total daily milk production for the whole herd.
( c )
Compute the increase in daily feed cost for the herd and state whether the increase in revenue (based on the milk price) justifies the higher feed cost.
( d )
Suggest two management practices, other than feed improvement, that could help sustain the higher milk yield.
