| 摘 要： | 为探讨牛胚胎移植受胎率、产犊成活率及后代生长发育情况,互助县先后从新疆呼图壁种牛场胚胎工程中心引进不同品种牛冷冻胚胎93枚,进行了胚胎移植试验.结果表明：平均受胎率为45.16%,产犊成活率为90.48%.黑白花、西门塔尔、利木赞、安格斯犊牛平均初生重为40.77,42.50,47.41,39.13,分别比同龄本地牛提高71.82%,79.10%,99.79%,64.90%;六月龄平均体重分别为116.74,123.36,134.15,120.49,分别比同龄本地牛提高64.80%,74.13%,89.37%,70.09%;12月龄体重分别为253.31,289.91,302.73,271.35,分别比同龄本地牛提高75.18%,100.51%,109.36%,87.66%;1周岁平均日增重分别为582.30g,677.84g,699.50g,636.22g.胚胎移植后代牛的生长发育较本地牛快.

| Abstract: | 93 Frozen embryos of cattle of different breeds were introduced into Huzhu county from the Centre of Embryo engineeving of Xinjiang Hutubi Breeding Catde Farm to explore the comception rate and calving survival rate of embryo transfer of cattle and the growth and development of their offsprings. These embryos of cattle were used to conduct the test of embryo transfer. The results showed that the average conception rate was 45.16% and the calving survival rate was 90.48%. The average initial weight of the calves of Holstein , Simmental Limousin and Angus breeds were 40.77,42.50,47.41 and 39.13kg which were increased 71.82%, 79.10%, 99.79% and 64.90% than that of native contemporary cattle, respectively; the everage weight of the calves at the age of six months were 116.74,123.36,134.15 and 120.49kg which were increased 64.80% ,74.13% ,89.37% and 70.09% than that of native contemporary cattle;the average weight of yearling cattle were 253.31, 289.91,302.73 and 271.35kg which were increased 75.18 %, 100.51%, 109.36 % and 87.66 % than that of native contemporary cattle, respectively ; the average daily gain of yearling cattle were 582.30,677.84,699.50 and 636.22g. The growth and development of embryo transfer cattle was faster than that of native cattle. |
