摘要
将30头30±2kg的育肥猪(长白×内江)随机分成试验组和对照组。对照组采用个体户原用添加剂,试验组采用自配高铜添加剂。结果表明:对照组日增重341.67g,料肉比4.0:1试验组日增重364.67g,料肉比3.7:1。两组日增重差异显著(P<0.05)。
Thirty crossed hogs weighing from 28 kg to 32 kg are divided at random into two groups named experiment group and versus group.The versus group uses the additive of the specialized factory's bleng . The experiment group uses the self- blended high copper addivive. The result demonstrates that the experiment group's daily gain is 364.67g,and the versus group's daily gain is 341.67 g.The two group's daily gains have a marked difference (0.01 < P < 0.05).
