Two trials were conducted in which male turkeys from commercial Strains A and B were fed diets calculated to contain 80, 100, or 120% of recommended levels of protein from 1 to 8 wk of age and recommended levels of protein at other ages. Feeding reduced protein diets decreased 8-wk BW of both strains. No difference in BW, however, was evident at 17 wk in either strain. Dietary protein level generally did not influence overall feed to gain ratios, feed intake, or behaviors of male turkeys from these two strains. Effects of dietary protein level on walking ability were inconclusive. The results of the present study indicate that it may be possible to reduce early dietary protein levels with savings in feed cost for male turkeys with no adverse effects on growth or feed conversion at market age.
进行了两项试验，将来自商业品系A和B的雄性火鸡从1至8周龄饲喂按计算含有推荐蛋白质水平80%、100%或120%的日粮，其他年龄则饲喂推荐水平的蛋白质。饲喂低蛋白日粮降低了两个品系8周龄时的体重。然而，在17周龄时，两个品系的体重均无明显差异。日粮蛋白质水平一般不影响这两个品系雄性火鸡的总体料重比、采食量或行为。日粮蛋白质水平对行走能力的影响尚无定论。本研究结果表明，降低雄性火鸡早期日粮蛋白质水平可能节省饲料成本，且对上市年龄时的生长或饲料转化率无不利影响。
