ANIMAL EMBRYO COMMERCIAL PRODUCTION BY USING IN VITRO FERTILIZATION TECHNOLOGY

摘要

For many years, industrialized nations have been using biotechnology for bothagricultureand animal husbandry. Embryo transfer in cattle becomes one of the mostexciting andprogressive procedures available to today's animal producers. Withconventionalproduction, the average cow produces six to seven calves in her lifetime.Embryotransfer can increase her reproduction efficiency to numerous calves per year,thinincreasing the selection opportunities many times. Along with artificialinsemination,embryo transfer offers progressive producers fascinating geneticopportunities.Bovine are one of the major food sources for human and the productivity rateof domesticanimals is a very influential factor for many developing countries. Incountries such asthe United States, Canada, and Australia, embryo transfer is a popular andstandardtechnique for the improvement of bovine breeds.All the current commercial available frozen cattle embryos are produced bymethodcombines techniques include artificial insemination (AI), pregnancy detection,embryoflushing and embryo freezing. The idea behind this technique is to obtain apregnant cowfirst, by means of AI. Then embryo inside the cow is "flushed"" out by buffersolution.Microscope is used to locate the embryo from the flushed solution. And thefinal stage isto freeze the embryo for storage or to perform embryo transfer.IND Lifetech Inc. has a unique method to mass product low-cost embryo forcommercialpurpose.
