精料补饲量对藏羊分娩后子宫复旧的影响
Effect of Concentrate Supplemental Level on Uterine Recovery of Tibetan Sheep after Parturition
摘要
Abstract
In order to research the effects of concentrate supplemental level on uterine recovery of Tibetan sheep after parturition, a total of 3-year-old 160 Tibetan sheep at the second parity with similar body status were chose and divided into four groups [groups Ⅰ, Ⅱ, Ⅲ and Ⅳ (control), 40 sheep in each group]. Sheep in experimental groups were all barn fed.The concentrate supplemental levels for groups Ⅰ, Ⅱ, Ⅲwere 0.50, 0.75, 1.00 kg/d for one sheep, respectively, while group Ⅳ was carried out traditional grazing. The pre-test lasted for 6 d, and the test lasted for 35 d.Body weight of sheep, uterine weight, sum of three di-ameters, area and height of leaf, the thickness of uterine wall were determined.The results showed as follows:weight gain of sheep in groupsⅡandⅢwas significantly lower than that of groupsⅠandⅣ( P<0.01) , and that of group Ⅰwas significantly lower than that of group Ⅳ ( P<0.01); with the increasing of concentrate supplemental level, uterine weight, sum of three diameters, uterine area and uterine height were declined, while thickness of uterine wall was increased;Tibetan sheep finished uterine recovery for groupsⅡand groupⅢ after 34 d of parturition.In conclusion, concentrate supplementation at 0.75 kg/d for one sheep can promote uterine recovery, and it finishes in 34 d after parturition.关键词
