Abstract
The present study was conducted on male Newzeland rabbits to investigate in a comparative approach the effects of bovine somatotropin and salbutamol on growth performance, carcass traits,and biosafety-related parameters. The recorded results revealed that, bovine somatotropin increased Average daily feed intake and live body gain. Both Bovine somatotropin and salbutamol decreased Feed conversion ratio and increased feed efficiency. While salbutamol increased dressing percentage, longissimus muscle protein concentration And plasma creatinine level, bovine somatotropin Has no effect on them. However, both promoters Decreased plasma urea concentrations. Bovine Somatotropin and salbutamol didn’t significantly Alter biosafety-related plasma parameters; activities of alanine aminotransferase, aspartate amino-Transferase and alkaline phosphatase, plasma total Proteins, albumin, urea, glucose, sodium, chloride, total and free calcium and inorganic phosphorus. In conclusion, Growth promoters; bovine Somatotropin or salbutamol are economic, profitable and safe for anímals and could be used for increasing both feed efficiency and protein accretion, and decreasing fat deposition.
