Question 6 NECO • 2022 • AGRICULTURAL_SCIENCE • essay

A smallholder keeps a dairy herd of 20 lactating cows. The average daily milk yield per cow is 12 L. Each cow weighs about 450 kg and consumes 2.5 % of her body weight as dry matter (DM) per day. The herd is fed a total mixed ration (TMR) that consists of maize silage (35 % DM) and a concentrate mix (90 % DM). The silage contains 4 % crude protein (CP) on a DM basis, while the concentrate contains 18 % CP on a DM basis. Cows require 3.2 % CP of their total DM intake.

Question Parts

( a )

Calculate the total daily DM intake of the herd (in kg).

( b )

Determine the amount of concentrate (in kilograms of as‑fed feed) that must be fed daily to meet the cows’ CP requirement.

( c )

If the farmer wishes to increase the herd’s milk yield by 10 % without changing the total DM intake, suggest one nutritional strategy and briefly explain the scientific basis for its effectiveness.
