普瑞纳3136号饲料育肥藏系羯羊效果分析

Effects of Purina 3136 Fattening Feed on Tibetan Sheep

将40只1岁龄青海藏系羯羊分为两组,通过饲喂试验对比普瑞纳育肥羊饲料与青海牧区当地自配料育肥效果,以研究两种精饲料对藏系羊生长性能及效益的影响。试验结果表明:对两组藏系羊同期进行60d补饲,自配料组初始体重21.97±0.78kg,结束体重35.20±1.49kg,平均日增重220.17±13.24g;普瑞纳饲料组初始体重21.89±0.91kg,结束体重40.16±1.86kg,平均日增重305.00±15.92g。经样本平均值差异性显著性分析,两组初始体重差异不显著(p>0.05),而结束体重与期间平均日增重普瑞纳饲料组极显著高于自配料组(p<0.01)。从效益上分析,普瑞纳饲料组每只羊比自配料组多收入98.68元。

This study was conducted to determine the effects of Purina 3136 fattening feed and local self--fattening ingredi- ents on the growth performance and economic benefits of Qinghai Tibetan sheep. Forty 1- year--old Qinghai Tibetan sheep were divided into two groups, supplemented with the two kinds of concentrated feed for 60 days. The results indicated that for local self--fattening ingredients group the initial and final weight were 21.97 ±0.78 kg and 35.20 ± 1.49 kg, the average daily weight gain was 220.17±13.24 g. For Purina 3136 fattening feed, the initial and final weight was 21. 89±0.91 kg and 40.16±1.86 kg, the average daily weight gain was 305. 004-15.92 g. No significant difference was observed between the two groups （P〈0.05）, however, final weight and daily weight gain of Purina 3136 fattening feed group were significantly higher than lo- cal self-fattening ingredients group （P〈0.01）. From the analysis of benefit, Purina 3136 fattening feed group earned 98.68 yuan more per sheep than local self-fattening ingredients group.
