Abstract

The current study intends to evaluate the effect of rumen-protected methionine (RPM) and lysine (RPL) supplementation on the growth performance of crossbred (HF×Kankrej) female calves. For this study, twelve crossbred female calves were randomly allotted to two groups T1 and T2 based on their body weight for the period of 98 days. Calves in the T1 group were fed basal TMR to meet the nutrient requirement as per ICAR (2013) standard and those in T2 were fed basal TMR same as T1 + 2 g/kg DM RPM and 6 g/kg DM RPL. The average biweekly and daily body weight gain was significantly (p<0.05) higher in the T2 compared to the T1 group. However, the total body weight gain was not affected between treatments. The DMI, CPI, DCPI and TDNI did not differ significantly between groups. The dietary treatments did not differ significantly with respect to feed conversion ratio (kg/kg gain). The cost of feeding (Rs/head/98d) was significantly higher in the T2 group than the T1 due to the higher cost of RPM and RPL. However, the cost of feeding (Rs/kg gain) did not exhibit any significant difference between groups. The results of the present study indicate the importance of supplementing RPM and RPL to the basal diet which results in improvement in growth performance without affecting the cost of feeding.

Conclusion

From the results obtained under the present study, it is concluded that the body weight gain (kg) was higher in crossbred female calves fed with standard protein basal diet supplementation with 2 g/kg DMrumen-protected methionine and 6 g/kg DM lysine without affecting feed intake and cost of feeding (Rs/kg gain).
