Abstract :

Twelve Jersey crossed cows in mid lactation with almost similar age, body weight and milk yield were randomly selected from dairy farm of Rajasthan gaushala. These were divided into two groups of six animals. Control group (T1), were maintained on conventional diet of wheat straw (WS) and concentrate supplement (CS). While other group, considered as treatment group (T2), was fed conventional diet plus urea mineral molasses block (UMMB) ad libitum for 60 days. The difference among the control and treatment groups in nutrient intake was significant (p≤0.05) except for EE intake. The average milk yield (kg/d) in groups T1 and T2 were 11.86+0.19 and 13.75+0.31, respectively which differedsignificantly (p≤0.05). Fat and SNF content (per cent) of milk in groups T1 and T2 were 3.76+0.16 and 3.97+0.16; 8.2+0.09 and 9.1+0.09, respectively, which did not differ significantly between the control and treatment group. The cost per kg of milk was Rs.6.94 and 6.53 in T1 and T2 respectively.It was concluded that feeding of UMMB along with basal diet influenced nutrient intake in treatment group cows. Whereas, feeding of UMMB significantly improved milk yield and composition in treatment group.
