Ten males and 10 females from each of five commercial broiler strains were weighed and slaughtered at 55 days of age. Over all, mean live body weight was 2112 g for males and 1702 g for females and abdominal fat was 2.9% (males) and 3.3% (females). Mean total fat in whole bird was 13.4% (males) and 15.1% (females). There were no statistically significant differences between strains at the 5% level. Correlation coefficients with percent abdominal fat were .29 for body weight (males) and .36 (females), for percent carcass fat .51 (males) and .77 (females), and for fat free carcass .26 (males) and .07 (females). Abdominal fat represented 22% of the total fat for males and females. The results obtained were similar to those found previously in this laboratory with one strain of broilers.
从五个商用肉鸡品系中各选取10只雄性和10只雌性肉鸡，在55日龄时称重并屠宰。总体而言，雄性肉鸡平均活体体重为2112克，雌性为1702克；腹部脂肪含量雄性为2.9%，雌性为3.3%。整只鸡的平均总脂肪含量雄性为13.4%，雌性为15.1%。在5%的水平上，各品系之间无统计学显著差异。体重与腹部脂肪百分比的相关系数，雄性为0.29，雌性为0.36；胴体脂肪百分比，雄性为0.51，雌性为0.77；去脂胴体，雄性为0.26，雌性为0.07。腹部脂肪占雄性和雌性总脂肪的22%。所得结果与该实验室之前对一个肉鸡品系的研究结果相似。
