Effect of challenge feeding on performance and
economics of milk production of crossbred cows:
The effect of 'challenge feeding' on performance and
economics of milk yield of crossbred cows was studied.
For this study 10 advance pregnant crossbred cows
were selected 60 days before expected date of calving
and were divided into 2 groups i.e. control (T 1) and
treatment (T
2) on the basis of milk yield, parity and
body weight. During the prepartum period, T1 cows
th
were offered 2.5 kg of concentrate per day from 60 day
nd
to 22 day prior to calving and 3.5 kg concentrate from
nd
22 day prior to calving till the day of parturition. The
cows in T2 were fed 3.5 kg concentrate per day from
