Abstract: The present study was under taken to evaluate the influence of propylene glycol, bypass fat and bypass protein on milk yield in early lactating cows. A total of twenty eight postpartum dairy cows were randomly allotted to four groups with seven animals in each group. The Group-I (T0) animals served as control without being fed any feed supplement. Group-II (T1) animals received propylene glycol once daily as a drench at the rate of 300 ml per head while Group-III (T2) and Group-IV (T3) animals were fed 100 and 200 g of commercially available bypass fat and bypass protein respectively. In all the groups, the average daily milk yield per day recorded at weekly interval increased linearly from day 7 to 63 postpartum. The increase in milk yield up to one month was not statistically significant. The mean daily milk yield recorded at weekly interval showed non-significant stage variation between groups at all stages from day 7 to 63 postpartum. However, the average daily milk yield recorded in Group-II, Group-III and Group-IV cows which received supplementation was apparently high from day 14 onwards compared to the Group-I. The pooled mean daily milk yield recorded in Group-II (16.010.24 kg), Group-III (15.920.23 kg) and Group-IV (16.000.24 kg) was significantly (P-0.05) higher than the pooled mean daily milk yield recorded in Group-I (14.520.18 kg) with no difference between themselves. Based on the results obtained it was deduced that supplementation of bypass protein, bypass fat and propylene glycol might result in increase in milk yield in early lactating cows.
