“…The chicks used were the progeny of New Hampshire males and Single Comb White Leghorn females fed diet B-l of Robblee et al (1948). They were placed on experiment when one day of age and maintained on raised wire floors in electrically heated batteries in a room that was illuminated continuously.…”

“…At the age of 10 weeks this ration was supplemented with a mixture of corn, wheat, and oats made up so as to supply 3 parts of corn, 2 parts of wheat, and 1 part of oats. At maturity, all the chickens were placed on a slightly different grain mash (Robblee et al, 1948).…”

Twenty-four New Hampshire pullets assigned at random to 6 sire groups were used to produce a total of 665 chicks. Each chick was injected with 0.6 mg. each of testosterone propionate and stilbestrol dissolved in sesame oil administered in 6 equal injections over a 12-day period. The chicks were then sacrificed and records made on body, comb, and oviduct weights. Analysis of the data revealed that there were significant differences between the sire families and between dam families within sire families with respect to body weight, comb weight, and oviduct weight. Since all chicks were subjected to relatively high androgen and' estrogen levels, these results indicate that these differences in weights are the result of differences in tissue response. Heritability values for the three measurements were as follows: Body weight 0.22, comb weight 0.13, oviduct weight 0.23.
