The Effect of Diethylstilbestrol-Methimazole and Dienestrol Diacetate on Turkey Broilers

Abstract

THE ability of administered estrin to produce lipemias in birds was demonstrated by Lorenz et al. (1938). Lorenz (1943) demonstrated that diethylstilbestrol could be used for fattening cockerels when it was implanted subcutaneously. Later Lorenz (1944) reported an increase in abdominal fatty tissue in turkeys when they were treated with diethylstilbestrol. Lorenz (1945) also reported that when diethylstilbestrol pellets were administered to chickens by subcutaneous implantation there was a marked increase in the fat content of the muscle tissue and in the quantity of depot fat. Thayer et al. (1945) found 3,4 dianisylhexene-3 to be more efficient for fattening chickens than diethylstilbestrol when fed orally. Levels of 40 to 50 mg. of dianisylhexene per pound of feed fed for a 3 to 4 week fattening period did not appear to effect growth rate, but body fat was increased. Gassner and Wilgus (1948) found that alpha-estradiol and methoxybisdehydrodoisynolic acid were ineffective …
