An experiment was conducted to study the effects of feeding diets composed of triticale (var: Flora) with varying ME levels and 7% CP on fertilizing capacity and semen quality of Medium White breeder toms. Thirty-nine breeder toms were fed ad libitum from 30 to 54 wk of age one of four dietary treatments: 14% CP with 2,892 kcal ME/kg; 7% CP with 2,919 kcal ME/kg; 7% CP with 2,719 kcal ME/kg; and 7% CP with 2,539 kcal ME/kg. Semen volume (SV), packed spermatozoa volume (PSCV), BW, testicular weight (TW), and fertilizing capacity of semen were measured. No differences for SV, PSCV, TW, calculated daily feed, and estimated energy consumption were observed among the dietary energy levels fed. The estimated daily protein intake was higher (P less than .05) for toms fed the 14% 2,892-ME diet than 2,539, 2,719, and 2,919-ME diets containing 7% CP. The 7% 2,919-ME diet reduced (P less than .05) the fertilizing capacity of spermatozoa, whereas the 7% 2,539-ME diet decreased the percentage of fertile eggs hatched. Under the conditions of this experiment, Medium White breeder toms maintained fertilizing capacity and semen quality when provided a diet containing 7% CP with 2,719 kcal ME/kg.
进行了一项实验，以研究饲喂含有不同代谢能（ME）水平和7%粗蛋白（CP）的小黑麦（品种：弗洛拉）日粮对中型白种公火鸡受精能力和精液品质的影响。39只种公火鸡在30至54周龄时自由采食四种日粮处理中的一种：14% CP且代谢能为2,892千卡/千克；7% CP且代谢能为2,919千卡/千克；7% CP且代谢能为2,719千卡/千克；以及7% CP且代谢能为2,539千卡/千克。测量了精液体积（SV）、精子 packed 体积（PSCV）、体重（BW）、睾丸重量（TW）和精液的受精能力。在所饲喂的日粮能量水平之间，未观察到SV、PSCV、TW、计算得出的每日采食量和估计能量消耗存在差异。饲喂14% 2,892 - ME日粮的公火鸡估计每日蛋白质摄入量高于饲喂含7% CP的2,539、2,719和2,919 - ME日粮的公火鸡（P < 0.05）。7% 2,919 - ME日粮降低了（P < 0.05）精子的受精能力，而7% 2,539 - ME日粮降低了孵化的受精卵百分比。在本实验条件下，当给中型白种公火鸡提供含7% CP且代谢能为2,719千卡/千克的日粮时，其维持了受精能力和精液品质。
