Intake,digestibility,performance,and carcass traits of beef cattle of different gender
Abstract
The performance,intake,feed efficiency,and carcass traits of beef cattle from different gender profile were assessed.Fifteen animals (five steers,five spayed heifers,and five intact heifers) with ±250 kg of initial body weight were randomly assigned in individual pens and fed the same diet for 106 days.At the end of the trial,all the animals were slaughtered and the pH,temperature,and weight of the carcass were recorded.The right side of each carcass was then separated into chuck,shoulder,flank sirloin,and round for evaluation of commercial cuts yield.The left carcass sides were ribbed between the 12th and 13th ribs where the rib eye area and fat thickness measurements were taken.The 9th–11th rib section was removed from the left half carcass and then dissected into muscle,fat,and bones in order to estimate carcass composition.Gender had no effect (P > 0.05) on performance,intake,digestibility of dry matter and all the nutrients evaluated,feed efficiency,and carcass characteristics.It can be concluded that steers and heifers (spayed or not) have the same potential to produce beef.From a productive and welfare standpoint,there is no reason to spay heifers.

不同性别肉牛的摄入量、 消化量、 性能和畜体特征
摘要
不同性别肉牛的摄入量、 消化率、 性能和畜体特征
本文对不同性别肉牛的性能、 摄入量、 饲料效率和畜体特征的概况进行了评估.从不同的牛圈中随机指定15头初始体重±250 公斤的肉牛 (五头公牛、 五头切除卵巢的母牛和五头原封不动的母牛) ,然后以相同的饲料喂养106天.在试验结束后,宰杀所有15头肉牛和记录其畜体ph值、 体温和体重.然后就每个畜体的右片分为颈肉、 肩肉、 侧腰肉,和圆肉来评价其商业切割产量.畜体的左片在12,13节肋骨间被剔骨,并测量肋眼部和脂肪厚度.将8至11节肋条之间部分从畜体的左片上剔除,然后再分解成精肉、 脂肪和骨骼,以评估畜体的组成.性别对于评估出的性能,摄入量、 干料消化率和各种营养的数值、 饲料效率及畜体没有任何影响 （P > 0.05） .因此可以断定,公牛和母牛 (无论切除卵巢与否）都可能产出同样的牛肉.从生产和福利的角度看,没有理由切除母牛的卵巢.
