the aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. we were worked a total of 23holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (pmsg) (2500 3000ui).69 cows were used as recipients of holstein dairy heifers with an age of20 months and...

Embryo Sexing in Cattle: Review

Predetermination of sex is of commercial importance since economic value of each livestock species is different for different sex. Embryo sexing enables the producers to run a fewer recipient female and thus quickly increase the size of their herd. The widespread use of embryo transfer technology has created an alternative approach in controlling the sex of offspring. The methods used can be gr...

Embryo Transfer in Beef Cattle

Embryo transfer is a multi-step process that involves the production and collection of preimplantation embryos from genetically superior females (called donors) and the subsequent transfer of the harvested embryos into reproductively healthy females (called recipients) for the purpose of establishing pregnancies and producing live offspring. The first successful embryo transfer in mammals was p...

Embryo Transfer in Beef Cattle Research

Embryo technology: implications for fertility in cattle.

During the past thirty years, basic and experimental studies on classical (superovulation; non-surgical recovery and transfer of cattle embryos) and advanced embryo technologies (in vitro embryo production; cloning by somatic cell nuclear transfer) have generated structural and functional information on oocyte development and quality, fertilisation and conceptus development. This information ha...
