波尔山羊超数排卵研究

Study on the superovulation in Boer goat

1999～2001年,分别在龙泉成都波尔山羊种羊场、邛峡四川波尔山羊种羊场分场、阳平四川波尔山羊种羊场、都江堰波尔山羊种羊场进行了波尔山羊超数排卵研究。对100只供体用FSH PG法进行了超排处理,回收胚胎1867枚,平均18 67±8 50枚,其中可用胚1584枚,平均15 84±7 70枚。研究结果表明:(1)用30%聚乙烯吡咯烷酮(PVP)溶液稀释后一次注射总剂量与用生理盐水稀释FSH递减法多次注射,平均每只获可用胚分别为19 0±11 1枚、22±1 00枚;(2)使用国产和进口激素FSH,平均每只获可用胚分别为15 94±8 33枚、15 15±5 03枚;(3)春秋两季超排,平均每只获可用胚分别为19 4±12 14枚、14 85±9 17枚;(4)波尔山羊体况好的,其超排效果好于体况较差的,平均每只获可用胚分别为16 80±8 75枚、13 32±6 53枚;(5)2～3胎母羊的超排效果好于经产4～5胎、育成羊和一胎羊,平均每只获可用胚分别为18 43±8 21枚、14 17±6 34枚、13 33±2 52枚、13 33±2 52枚。以上结果经统计分析,差异不显著。

From 1999 to 2001,a study on the Boer goat superovulation was conducted in four Boer Goat Farms separately.Superovulation of 100 Boer goats were induced by injection FSHPG of two kinds of methods.1867 embryos were collected,and the average embryos per donor were 1867±850,of which 1584 were usable embryos,and the averages of usable embryos per donor were 1584±770.The results showed:(1)If total doses of 30% PVP dilution FSH one time injection and multiinjection of descending doses of PSS dilution FSH were used to superovulate Boer goats,average 190±111 and 22±100 usable embryos per goat could be obtained (P＞005),respectively;(2)When Boer goat superovulation was conducted by injection FSH produced in China and Australia,average 1594±833 and 1515±503 usable embryos per goat could be obtained (P＞005),respectively;(3)If Boer goat superovulation was conducted in spring and autumn,average 194±1214 and 1626±907 usable embryos per goat could be obtained (P＞005),respectively;(4)The result of superovulation was better when Boer goat was in middle highclass body condition than that in middle lowclass body condition,and average 1680±875 and 1332±653 usable embryos per goat could be obtained (P＞005),respectively;(5)The result of superovulation was good when Boer goat was at fertility exuberant stage,average 1843±821 usable embryos per goat could be obtained.Statistical analysis showed that above results were not significantly different.
