Abstract (en)
[origin: WO8503440A1] The growth rate of meat-producing animals as well as the yield and quality of the meat obtained therefrom is improved by administering to the animal prior to its sexual maturation an effective amount of a female gonadal steroidal compound; namely, an estrogen or progestagen compound and preferably a mixture thereof, sufficient to delay development of the gonadal function of the animal. Such administration is terminated sufficiently prior to slaughter of the animal that the administered steroidal compound has been substantially completely removed from the animal's system which before slaughter exhibits levels of the corresponding natural hormones therein substantially within normal limits. In mammals, administration is preferably by injection, but in fish, shellfish and poultry, the active steroidal compound is incorporated at low levels in the usual feed therefor. In mammals, the treatment is preferably applied to uncastrated males but can be extended to females and castrated males if desired; while in fish, shellfish and poultry administration is without regard to sex. The ratio of lean meat to fat is increased significantly by the treatment and in male mammals aggressiveness and odor development with consequential tainting of the meat is suppressed until slaughter.
