Abstract

IN a previous study the injection of high doses of thyroxine with vitamin deficient New Hampshire chicks revealed certain thyroxine-vitamin interrelationships. The work presented in the present paper is a continuation of these studies. Cockerels fed an adequate diet respond to testosterone propionate treatment by increased development of the comb and wattles and a decrease in testis size. In females, the injection of estrogen causes a marked increase in size of the oviduct. In this study, vitamin deficient chicks were treated with testosterone or estrogen and their response compared to that of chicks fed adequate diets. Breneman (1940) found that limiting the food of chickens not only resulted in a suppression of body growth but also produced testes that were smaller in actual weight and smaller in proportion to body weight. Serious nutritional disturbances have been shown by many workers to repress reproductive capacity (Evans, 1928; Guilbert and Hart, 1930; . . .
