摘要：

旨在研究35～50 kg杜泊×晋中绵羊F1代公羔铜（Cu）、铁（Fe）、锰（Mn）、锌（Zn）在体内分布特点及其净需要量。试验选取杜泊×晋中绵羊F1代公羔30只，采用比较屠宰试验，在试验羊平均体重达到35 kg时，随机抽取6只进行屠宰，作为初始屠宰组（BL），用于估测试验羊初始体组成；另随机选取6只羊，自由采食并在平均体重达到43 kg时屠宰，作为中期屠宰组（M）；剩余18只羊分为3个饲喂水平组：自由采食组（AL）、65%限饲组（65%）和40%限饲组（40%），当自由采食组的平均体重达到50 kg时，剩余18只羊全部屠宰。屠宰后，分别测定肌肉、脂肪、骨骼、血+内脏、羊皮、羊毛中铜、铁、锰、锌含量，建立数学模型分析微量元素在体组织中的分布规律，并预测其净维持及净生长需要量。结果表明，随着体重的增加，公羔骨骼、肌肉生长速度逐渐降低，脂肪生长速度逐渐增加。铜、铁、锰主要分布于内脏（血液）中，分别占体内总含量的86.34%、49.12%、68.65%，锌主要分布于肌肉和骨骼中，分别占体内总含量的42.17%、24.19%。35～50 kg杜泊×晋中绵羊F1代公羔铜、铁、锰、锌净维持需要量以空腹体重（EBW）表示分别为0.016、0.281、0.007和0.085 mg•kg^-1 EBW•d^-1，以体重（BW）表示分别为0.013、0.228、0.006和0.069 mg•kg^-1 BW•d^-1；净生长需要量以空腹体重（EBW）表示分别为12.61～15.62、77.82～82.55、2.74～3.45和25.36～23.98 mg•kg^-1 EBW，以体重（BW）表示分别为10.17～12.75、62.76～67.39、2.21～2.82 和20.45～19.57 mg•kg^-1 BW。本研究中公羔微量元素维持需要量除锌略低外，其他都高于NRC（2007）推荐量；铁、锌净生长需要量与NRC（2007）推荐量接近，而铜、锰需要量较推荐量高。

Abstract:

This experiment was conducted to estimate distributions of Cu, Fe, Mn, Zn and the net requirements for maintenance and growth of Dorper × Jinzhong crossbred ram lambs at 35-50 kg. A total of 30 ram lambs were used in this experiment. A comparative slaughter trial was carried out, and 6 lambs were randomly chosen and slaughtered at approximately 35 kg BW as the baseline group for measuring initial body composition. Another 6 lambs were also randomly chosen and offered a pelleted mixed diet for ad libitum intake and slaughtered at approximately 43 kg BW. The remaining 18 lambs were equally assigned to 3 groups in a randomised design according to the level of dry matter intake (ad libitum or 65% or 40% of ad libitum intake of the same diet), the 3 groups were slaughtered when the sheep fed ad libitum reached approximately 50 kg BW. The contents of Cu, Fe, Mn and Zn in different tissues, including muscle, adipose, bone, blood+visceral, leather and wool, were measured; mathematical model for analyzing distributions of trace element in tissues and predicting trace element requirements for maintenance and growth were established. The results showed that the growth rate of bone, muscle and fat decreased, decreased and increased, respectively. Cu, Fe Mn were mainly stored in viscera, accounting for 86.34%, 49.12%, 68.65% of the total contents in body, while Zn was mainly stored in muscle and bone, accounting for 42.17%, 24.19% of the total contents in body. The net requirements for maintenance of Cu, Fe, Mn, Zn expressed as empty body weight (EBW) were 0.016, 0.281, 0.007 and 0.085 mg•kg^-1 EBW•d^-1, and expressed as body weight (BW) were 0.013, 0.228, 0.006 and 0.069 mg•kg^-1 BW•d^-1, respectively. Net requirements for growth expressed as empty body weight (EBW) were 12.61-15.62, 77.82-82.55, 2.74-3.45 and 25.36-23.98 mg•kg^-1 EBW, and expressed as body weight (BW) were 10.17-12.75, 62.76-67.39, 2.21-2.82 and 20.45-19.57 mg•kg^-1 BW, respectively. The net requirements for maintenance of trace element in this study were higher than that recommended by NRC, excepted for Zn; net requirements for growth of Fe and Zn were similar with the recommendation of NRC, while requirements of Cu and Mn were higher than the recommendation.
