“…The data reported in Table 1 and Figure 1 are relevant to this discussion. The incremental gain relative to feed inputs for the treated fryer was significantly (P<0.01) greater than for the untreated fryers during the six to eight week period (Stadelman et al, 1951). Also for any given input of feed (after the sixth week) the total weight for treated fryer was greater than for the untreated fryer, as shown in Table 1 and illustrated in Figure 1.…”

“…Stadelman et al (1951) reported a significantly (P<0.05) higher dressed weight for such treated fryers relative to non-treated fryers. This finding has economic significance to fryer producers, handlers, and consumers only insofar as the fat is deposited as an integral part of the edible portion of the carcass.…”

“…Recent research findings indicate that the use of diethylstilbestrol improves the fleshing and market grade, as well as increases the fat deposition and dressing percentage. (Lorenz, 1943(Lorenz, , 1945Andrews and Bohren, 1947;Detwiler et al, 1950;Stadelman et al, 1951. ) PROBLEM AND HYPOTHESES In developing this particular problem (viz., is it possible to treat fryers with diethylstilbestrol and increase economic returns to everyone more than by a system of non-treatment?…”

Two groups of meat-type cockerels, 56 d of age, from the same hatch but of different mean live-weights (1135 g ± SD 96.2 and 544 g ± 72.0) due to differences in earlier nutritional treatments were implanted with hexoestrol to determine the effects on food consumption, live-weight gain, carcass gain, chemical composition of carcass and offal, and weight of some body components. Replicate groups were slaughtered prior to implantation and at the end of the 28-d experimental period.Implantation with a single 15 mg hexoestrol pellet resulted in the following significant differences compared with untreated controls: increases in food consumption, live-weight gain, carcass weight and weight of offal of 21.5, 14.2, 8.2 and 16.6 per cent respectively; poorer food conversion, higher total fat in the carcass, offal and total body and, relative to body weight, heavier livers and lighter hearts, gizzards, legs and necks. The increased fat in treated chickens accounted for all the increased body weight and carcass weight.In comparisons of small and large chickens there was no significant difference in live-weight gain during the 28-d experimental period. At both 56 and 84 d of age the dressing percentages were lower and the weights relative to body weight of offal, liver, shanks and gizzards were higher in small than in large chickens. Percentage moisture was significantly higher in the total bodies and carcasses of small chickens, while percentage fat was significantly lower in the carcasses of small chickens at both 56 and 84 d and in the total bodies and offals at 56 d.
