Abstract:
The present study was undertaken to ascertain the effect of supplementation of horse gram based bypass protein on certain serum and milk biochemical components in Holstein Friesian crossbred cows. A total of 24 animals in their 4^th lactation with low SNF syndrome were selected for the study and were grouped in to four groups. Group I animals that were fed with only basal diet served as control group. Group II, Group III and Group IV animals were fed with soaked and grinded horse gram, heat treated and powdered horse gram and commercially available bypass protein, respectively, in addition to the basal diet. The blood and milk samples were collected from all the animals when they are in their 4^th and 8^th week of lactation. The blood samples were immediately utilized for blood glucose determination. Serum obtained from blood samples were utilized for β-hydroxybutyrate (BHB), total protein, albumin and urea nitrogen. The milk samples were screened for protein, lactose, SNF and milk urea nitrogen. Results indicated that the blood glucose levels were significantly higher in supplemented groups animals compared to control group animals. Serum total protein and serum albumin values were significantly higher in group IV animals compared to Group I animals at 4^th week of lactation however, the values were significantly (p<0.05) higher in all the supplemented group animals compared to control animals at 8^th week of lactation. Milk protein levels were significantly higher in animals fed with commercial bypass protein compared to control group animals at 4^th and 8^th week of 4^th lactation. It was concluded that the supplementation of horse gram based bypass protein to HF crossbred animals with low SNF at their 4^th lactation improved the levels of blood glucose, serum total protein, albumin and milk protein. However, it did not influence the other components significantly.
