Twinning In Cattle :: essays research papers fc

Twinning in CattleDue to the persistent fluctuation of the cattle market cattle let onrs boast been searching for ways to improve their production and enlarge theirprofits any way possible. For geezerhood genetic engineers have been working hard onimproving economical efficiency in cattle. It is their hope that through geneticresearch they advise improve the yield and the income of cattle producers aroundthe world. Research has shown that twinning is adept way that farmers can increasetheir yield . Twinning has a profound influence on producers as well aspeople who argon involved in all realms of agriculture. The reason for this largeimpact at this time is the fact that the occurrences are limited. However, manyproducers have a spate that twinning can be more than a once in a blue moonoccurrence. These producers read twinning as a way to dramatically increase theiryield per calving season. Producers will increase their income due to moreweight per year per cow. It is nece ssary nevertheless, that the producer be welleducated on how to handle twinning, in order for it to be successful for them.Many agencies see twinning as an economic race upward. The AmericanBreeder Service has made efforts to produce semen as well as conceptuss with highpredicted breeding values available to producers. They have been recorded foundon twinning probabilities and ovulation rates. A large make sense of work ontwinning has overly been done by the stub and Animal Research Center. Since theearly eighties, they have located cattle with a high frequency of twinning andbeen forming a breeding foundation based on this characteristic. We believe thetime has come to make some of these singular genetic resources available to thebeef industry through artificial insemination and fertilized egg transfer (Gregory 23).An extensive amount of research has been done using embryo transfer in cattle.In one study recipients were implanted with each a single embryo, two embryoin on e uterine horn, or one embryo in each uterine horn. It is also possible tosplit embryos using a micro manipulator and implant each half to produceidentical twins. On the average close 16% of the cows implanted with two embryosproduced twins. When two embryos were implanted, and one was lay in each horn,conception rates were comparable with the prior method, however the twinningrate was much higher when the embryos were in separate horns (73% vs. 45%). Forthe most part, when one embryo was split in an attempt to produce identicaltwins, only one of the offspring survived birth (Davis 302).Many producers see twinning as a possible advancement in
