Response of Nigerian zebu cattle to zeranol implants.
The effect of Zeranol, an anabolic agent, on the weight gains of Nigerian zebu fattening bulls was investigated over a period of 16 weeks. Implanted Sokoto Gudali and White Fulani bulls showed average daily weight gains of 0.5 and 0.49 kg respectively as compared to 0.47 and 0.41 kg by non-implanted counterparts. The anabolic effect of Zeranol was evident up to 8 to 9 weeks after implantation, after which there was no significant difference in weight gains of implanted and control animals.
