摘要
在5个不同饲养管理条件的波尔山羊种羊场对体况较好和较差的69只母羊超排情况进行了比较研究。结果表明,对体质较差羊群的母羊实施超排处理时,回收卵平均数和可用胚平均数均低于体质较好的母羊群,虽然未表现出统计学差异,但有下降的趋势。在不同羊场使用同品种受体奶山羊进行胚胎移植试验结果表明,饲养管理条件差的羊场Ⅱ,一月龄羔羊存活率为81 7%(76/93),显著低于其他的场,羊场Ⅰ、羊场Ⅲ、羊场Ⅴ分别为98 9%(87/88)、96 6%(197/204)、97 8%(89/91);羊场Ⅱ胚胎成羔率为49 2%(93/189),显著低于羊场Ⅲ和羊场Ⅴ,其分别为60 5%(204/337)、67 9%(91/134)。
Superovulation was conducted on 68 Boer Goats of the different body condition in five farms by the different feeding and management. The results revealed that superovulation effect in good donors body condition was better than that in middle-low body condition(P>0.05).Embryos were transferred to 445 recipients of milk goat in five farms by the different feeding and management. Embryo transfer of the different body condition donor were conducted. The survival rate of one month kids was 81.7 %(76/ 93) in the farm 2 with lower feeding management condition,which was lower significantly than that in other three farms,which were 98.9 %(87/ 88), 96.6 %(197/ 204) and 97.8 %(89/ 91) (P<0.05), respectively. The rate of embryo developing to kids was 49.2 %(93/ 189) in the farm 2,which was significantly lower than that in the farm 3 and 5,which were 60.5 %(204/ 337),67.9 %(91/ 134)(P<0.05),respectively.
