DIMOV, K. and M. TZANKOVA, 2002. Biological effectiveness of the meat performance in buffalo and cattle bullocks. Bulg. J. Agric. Sci., 8: 269–274
A study on the biological effectiveness of the meat performance of buffalo and cattle bullocks fattened to different pre-slaughter weight was made.
It was established that by increasing the pre-slaughter weight of buffalo bullocks from 400 to 500 kg, the daily gain decreases by 15.96% and the utilization of feed deteriorates by 40.30%.
The buffalo bullocks fattened to 400 kg body weight have highest coefficients of biological gain effectiveness (16.57%), of the carcass (14.43%) and of the meat (11.71%) compared to the buffalo bullocks fattened to 450 and 500 kg.
By increasing the pre-slaughter weight to 500 kg, the cattle bullocks have considerably better coefficients of biological performance effectiveness than the buffalo bullocks.
