摘要
采用不同饲料配方对80只12月龄放牧藏羔羊(其中40只纯藏羔羊,40只含75%藏羊血液藏陶杂交羊)进行90 d全舍饲育肥,两组试验羊每天供给相同量精粗料,试验结果表明,藏羔羊试验Ⅰ组和试验Ⅱ组试验末增重分别为12.78 kg和8.85 kg,试验Ⅰ组较试验Ⅱ组提高3.93 kg;试验Ⅰ、Ⅱ组羊日增重分别为142 g和98 g,试验Ⅰ组比试验Ⅱ组提高44g,差异显著(P<0.05)。藏陶羊试验Ⅰ组和试验Ⅱ组总增重分别为14.36 kg和13 kg,试验Ⅰ组较试验Ⅱ组提高1.36kg,差异不显著(P>0.05)。试验Ⅰ、Ⅱ组羊日增重分别为159.56g和144.44 g,试验Ⅰ组比试验Ⅱ组提高15.12 g。同时,试验Ⅰ组羊育肥经济效果高于试验Ⅱ组。表明试验Ⅰ组饲料配方更适于本地藏羔羊育肥生产,具有较高的推广价值。
Eighty 12-month-old Tibetan lambs (40 pure Tibetan lambs and 40 Tibetan and Dorset hybrid sheep with 75% Tibetan sheep blood) were fed and fattened in house for 90 days with different feed formulas. The experimental sheep of two groups were fed with the same amount of concentrate and crude feed every day. The results showed that the final weight gain of Tibetan lambs in test group I and test group II were 12.78 kg and 8.85 kg respectively, and group I was 3.93 kg higher than that in group II;the daily gain of sheep in group I and group II was 142 g and 98 g respectively,and the daily gain of sheep in group I was 44 g higher than that in group II (P<0.05). As to the Tibetan and Dorset hybrid sheep, the total weight gain of group I and group II was 14.36 kg and 13 kg respectively, and group I was 1.36 kg higher than that of group II, with no significant difference (P>0.05);the daily gain of sheep in group I and group II was 159.56 g and 144.44 g, respectively,and the daily gain of sheep in group I was 15.12 g higher than that in group II. At the same time, the economic effect of sheep fattening in test group I was higher than that in group II. In conclusion, the feed formulas of test group I was more suitable for local fattening production of Tibetan lambs and had the higher popularization value.
