摘　　要：为研究不同来源、不同类型的胚胎对受体牛胚胎移植受胎率的影响,对比分析胚胎移植综合成本和效益,2024年4—6月,在天津地区移植奶牛胚胎90枚,受体牛平均受胎率达到65.55%。结果表明:不同来源、不同类型的胚胎移植后,受体奶牛的受胎率存在较大差异,自产体内A级和B级常规胚胎移植受胎率(66.67%)低于进口奶牛A级常规胚胎(76.67%),高于自产A级和B级体内性控胚胎移植(53.54%),组间比较差异均达到显著水平(P<0.05);比较分析了不同来源、不同类型的胚胎移植综合成本,自产体内常规胚胎综合成本最低(733元·枚-1),低于自产体内性控胚胎和进口常规胚胎,各试验组间差异均达到显著水平(P<0.05),从受孕牛头均成本分析来看,自产体内常规胚胎头均成本(1099元·枚-1)低于自产性控胚胎和进口常规胚胎,成本差异显著(P<0.05)。综上,在不考虑产犊性别及其生物资产价值的情况下,自产体内胚胎相比进口奶牛胚胎具有综合成本优势,应进一步优化胚胎移植关键技术环节,降低综合成本,加快推进奶牛遗传改良工作进程。In order to study the effects of different sources and different types of embryos on the tire transplantation rate of receptor beef embryo,and compare the comprehensive cost of embryo transplantation.From April to June 2024,90 dairy embryos were transplanted in Tianjin,recipient cattle with an average pregnancy rate of 65.55%.The results showed that the pregnancy rates different types and sources of embryos varied significantly.The pregnancy rate of routine embryo in vivo produced conventional A and B grade embryos(66.67%)was lower than of imported A grade conventional embryos(76.67%),but higher than that of in vivo produced A and B grade sex-sorted embryos(53.54%).The differences between groups were significant(P<0.05).The comprehensive costs of different sources and types of embryos were compared.The lowest comprehensive cost of conventional in vivo embryos(733 yuan per embryo),which was lower than that of in vivo produced sex-sorted embryos and imported conventional.The differences between groups were significant(P<0.05),Judging from the average cost analysis of the average cost of surrogacy,the average cost of conventional embryos(1099 yuan per embryo)in vivo embryo was lower than the self-produced embryo and imported conventional embryos,and the cost difference was significant(P<0.05).In conclusion,without considering the gender of calves and their biological assets,the self-producing internal embryo has a certain comprehensive cost advantage compare to imported dairy embryos.It should further optimize the key technical links of embryonic transplantation,reduce comprehensive costs,and accelerate the promotion of the genetic improvement in dairy cows.
