Abstract:
The present study was undertaken to analyze and compare the milk composition of Sahiwal and crossbred cattle under farm condition. Milk composition parameters were estimated for 48 (24 Sahiwal and 24 crossbred) dairy cattle. The relationship between milk compositional parameters was also investigated. The results of the study indicated that fat (p<0.001), SNF (p<0.05), and total solid % (p<0.001) were significantly higher in Sahiwal as compared to crossbred cattle milk. Milk composition parameters were significantly (p<0.05) affected by lactation. Fat, SNF, protein, lactose, and total solids (TS) % showed a decreasing (p<0.05) trend from 1^st lactation to 4^th lactation with highest mean values is 1^st lactation in Sahiwal milk. Milk composition did not show significant changes in different lactation of crossbred cattle except fat% While determining the correlation, fat showed highly significant (p<0.01) correlation with SNF, protein, TS and lactose (p<0.05) in both Sahiwal and crossbred dairy cattle. There was significant (p<0.05, p<0.01) positive correlation of SNF with protein, lactose and TS. TS had highly significant (p<0.01) positive correlation with protein and lactose in both the groups. The milk composition was found to change significantly with breed and lactation.
