Abstract
Pregnant crossbred cows were exposed to more oxidative stress during
transitional period from prepartum to early lactation due to metabolic needs,
hormonal changes, initiation of lactation and disturbed homeostasis mechanism.
Genetic selection for greater performance in the absence of consideration for heat
tolerance will result in greater susceptibility to heat stress. To mitigate these
stressors the present study was conducted on Asparagus racemosus
supplementation and its effect on prepartum, postpartum and environmental heat
stress in crossbred cattle.
For this study, twelve healthy pregnant Jersey crossbred cows were
randomly chosen and divided equally into experimental and control groups based
on parity and body weight. The experimental group which were supplemented
with Asparagus racemosus root powder 4 weeks before parturition @ lOOmg/kg
body weight and @ 200mg/kg body weight for 4 weeks during postpartum and
summer period. Blood and milk sample were collected on weekly basis during the
study period and milk yield measured daily.
