Abstract
The attempt was made to study the nutrients utilization by growing animals fed a ration containing 0,15 and 30 per cent level of rubber seed cake in the concentrate mixture. For this metabolism trial was conducted on male Kankrej calves.The results per cent dry matter consumption indicated 2.34 to 2.39 kg./day/100 kg body weight showing thereby that animals consumed sufficient amount of ration containing rubber seed cake. The digestibility of most of the proximate nutrients did not show marked difference between the treatments. The balance data revealed that nitrogen retention decreased with increasing levels of rubber seed cake in the ration, However, the differences were found to be non significant. The phosphorus balance was positive under all the treatments. Similarly the calcium retention was positive under all the treatments and showed reverse trend than that of nitrogen retention, but the differences were not significant.Thus overall result of rubber seed cake feeding indicate that there was no adverse effect on digestibility and balance. Hence, it was concluded that rubber seed cake can be incorporated in the concentrate mixture of growing calves upto 30% level.
