供体母羊及与配公羊个体对波尔山羊胚胎移植效率的影响

Effects of Boer goat donor and service ram on the embryo transferring rate

对135只波尔山羊供体母羊进行超排处理,回收卵总数2504枚,平均18 55±7 63枚,其中可用胚2182枚,平均16 16±7 46枚。将2127枚鲜胚移植给1182只受体,妊娠率为63 03%(745/1182),移植胚胎成羔率为52 1%(1108/2127)。试验结果表明,供体各个体之间所获得的胚胎移植成羔率存在着显著差异(P<0 05),胚胎成羔率大于80%的供体平均每只获胚胎移植羔羊14 8±4 27只,胚胎成羔率小于20%的供体平均每只获胚胎移植羔羊1 83±1 17只,其中个体获得羔羊最多的为21只(21/26)。有9 63%的供体胚胎移植成羔率大于80%,有4 44%的供体胚胎移植成羔率小于20%。14只公羊配种的135只供体获得的胚胎可用率同样存在着显著差异(P<0 05)。

Superovulation was conducted on 135 Boer Goats in five farms.A total of 2504 embryos were collected,the average of per donor were 18.55±7.63,in which 2182 were usable embryos, and the average usable embryo per donor were 16.16±7.46.Two thousand and twentyseven embryos were transferred to 1182 recipients.The pregnancy rate was 63.03?%(745/1182) and the rate of embryo developing to kids was 52.1?%(1182/2127).The results showed individual difference of donors was significant for the rate of embryo developing to kids(P<0.05).The average kids of per donor were 14.8±4.27 for donors,in which the rate of embryo developing to kids was higher than 80?%.The average kids of per donor were 1.83±1.17 for donors,in which the rate of embryo developing to kids was lower than 20?%.The kiddding rate was higher than 80?% for 963?% of the donors,and the kidding rate was lower than 20?% for 4.44?% of donors.The rate of usable embryo in donors were significantly different among service rams(P<0.05).
