Methods of Embryo Sexing in Cattle Breeding: A Review
Different livestock sectors as beef industries get benefit from the production of male animals while dairy industries get benefit from the milk production by the female animals. Therefore, it is obvious need to produce the animals of desired sex which can be achieved by predetermining the sex of conceptus at the time of conception i.e. pre determination of sex may be of great economic importanc...
متن کاملCloning in cattle: from embryo splitting to somatic nuclear transfer.
The ability to obtain genetically identical offspring in cattle (clones) is useful for research and for potential applications to breeding schemes. Experimental possibilities for generating such animals have evolved considerably in the last two decades. Embryo splitting has become a relatively simple technique but is limited to twinning. Embryonic nuclear transfer has improved and is associated...
متن کاملIn vitro production of bovine embryos using flow-cytometrically sexed sperm
The investigation aimed to compare the effect of fresh and frozen-thawed X and Y fractions of flowcytometrically sorted bovine spermatozoa on in vitro fertilization of bovine in vitro matured oocytes and subsequent blastocyst development. Sperm cells sorted in MoFloSX cytometer were used either for IVF or frozen and stored in liquid nitrogen. Immature oocytes recovered from ovaries of slaughter...
متن کاملState of the Art of Reproductive Biotechnologies in Buffaloes
Buffalo holds the unique potentiality among the livestock sector at tropical and subtropical area. The faster multiplication of superior genotypes and the conservation of endangered buffalo breeds are the important issue. Recent advances in assisted reproductive technologies (ART), including estrus/ovulation synchronization, multiple ovulation and embryo transfer (MOET), in vitro embryo product...
متن کاملAn Overview of Sex Selection at Conception in Mammals
Although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. The methods of sperm separation that have been repeatedly reported to isolate fractions rich in X- or Y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. However, the ability of the se...
