不同剂量褪黑素对多浪羊受胎及产羔效果的影响
Effects of Different Doses of Melatonin on Duolang Sheep Pregnancy and Lambing Effect
摘要
Abstract
[Objective] To study the influence of melatonin on Duolang sheep pregnancy and lambing effect,to select the optimal amount to improve the pregnancy rate and lambing rate and improve the reproduction rate.[Method] This study selected 57 Duolang sheep ewes with similar age,parity and body condition from November 2016 to April 2017 to conduct experiments in the professional farmers' cooperatives in Luopu County of Hotan area.Sheep were randomly divided into three groups at the same time for the same period of estrus,and after the withdrawal of 36 hours,the test group Ⅰ was injected melatonin 1 mL (5 mg),the test group Ⅱ 2 mL (10 mg),the control group 0ml.And before the burying bolt (12 o'clock midday),bolt withdrawal (12 o'clock midday),36 hours after the bolt withdrawal (12 o'clock midnight),the breeding (48 hours after embolization,serum withdrawal) of the five time periods for 20 days after the acquisition of its breeding,melatonin contents were determined and analyzed by radioimmunoassay;forty-fifth days after mating,they went through B-monitoring assay in three groups' pregnancy for the lambing rate;After the birth,the lambing rate of the three groups was compared.[Result] The test results showed that the pregnancy rate of test group Ⅰ was significantly higher than that of the test group Ⅱ and the control group (P ＜ 0.05),there was no significant difference between test group Ⅱ and control group (P ＞ 0.05);As for the the lambing rate,comparison between the three groups demonstrated no significant difference (P ＞ 0.05).[Conclusion]When treating Duolang sheep estrus,subcutaneous injection of 1 mL,2 mL melatonin 36 hours after the withdrawal of thrombus can improve the pregnancy rate.The pregnancy rate of 1 mL injection amount is higher than that of 2 mL injection,but no significant effect is found on the lambing rate.关键词
