为探讨日粮铜对断奶仔猪血清生长相关激素水平和生产性能的影响，将60头断奶仔猪随机分为6组，每组10头，分别饲喂基础日粮（对照组）、100、150、200、250和300 mg/kg硫酸铜，试验期80 d。每隔20 d测定平均日增重（ADG）、料重比（F/G）、采食量和血清生长激素（GH）、胰岛素（INS）、胰岛素样生长因子1（IGF-1）、胰岛素样生长因子结合蛋白3（IGFBP-3）水平。结果表明，在日粮中添加100、150、200、250和300 mg/kg硫酸铜可显著提高猪的日增重和血清GH、INS、IGF-1和IGFBP-3水平。添加250 mg/kg硫酸铜组，试验第40 ~ 60 d日增重显著提高（P< 0.01），试验第20 ~ 40 d血清GH、INS、IGF-1、IGFBP-3水平显著升高（P< 0.01）。因此，铜对猪生长的影响可能与铜诱导血清GH、INS、IGF-1、IGFBP-3水平升高有关。高铜日粮能提高断奶仔猪血清中生长相关激素的含量，从而提高断奶仔猪的生长性能。
To investigate the effect of dietary copper on serum growth-related hormones levels and growth performance, a total of 60 weanling pigs were randomly assigned to six groups each containing 10 pigs, fed on basal diets supplemented with 0 (control), 100, 150, 200, 250, and 300 mg/kg copper sulfate for 80 days, respectively. The average daily gain (ADG), feed to gain ratio (F/G), feed intake and serum growth hormone (GH), insulin (INS), insulin-like growth factor 1 (IGF-1), and insulin-like growth factor-binding protein 3 (IGFBP-3) levels were detected at interval of 20 days. The results revealed that ADG, and serum GH, INS, IGF-1, and IGFBP-3 concentrations were increased significantly in the pigs fed on diets added with 100, 150, 200, 250, and 300 mg/kg copper sulfate. Meanwhile, in the pigs supplemented with 250 mg/kg copper sulfate, ADG was increased significantly from the 40th to the 60th day of the experiment (P< 0.01), and the levels of GH, INS, IGF-1, and IGFBP-3 in serum were elevated significantly from the 20th to the 40th day of the experiment (P< 0.01). It is concluded that effects of copper supplemented in the diet on the growth of pigs were related to the increasing levels of GH, INS, IGF-1, and IGFBP-3 in serum which were induced by copper. High dietary copper increase the concentrations of growth-related hormones in serum, resulting in improving the growth performance of weanling pigs.
