Twinning In Cattle :: essays research papers fc

fit in kineDue to the continual fluctuation of the cattle market cattle staters substantiate been searching for ways to improve their production and increase theirprofits all way possible. For years heritable engineers take over been working hard onimproving economic efficiency in cattle. It is their hope that through and through geneticresearch they can improve the yield and the income of cattle producers aroundthe world. look for has shown that fit is one way that farmers can increasetheir yield . Twinning has a significant influence on producers as well aspeople who are involved in all realms of agriculture. The reason for this full-grownimpact at this time is the fact that the occurrences are limited. However, manyproducers have a vision that twinning can be more than a once in a blue moonoccurrence. These producers see twinning as a way to dramatically increase theiryield per separate season. Producers will increase their income due to moreweight per year per cow. It is essential however, 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 move upward. The AmericanBreeder Service has made efforts to produce semen as well as embryos with highpredicted life determine available to producers. They have been recorded basedon twinning probabilities and ovulation rates. A large amount of work ontwinning has also been do by the Meat and Animal Research Center. Since theearly eighties, they have set(p) cattle with a high frequency of twinning andbeen forming a breeding foundation based on this characteristic. We believe thetime has come to fool some of these unique genetic resources available to thebeef industry through artificial insemination and embryo transfer (Gregory 23).An extensive amount of research has been do using embryo transfer in cattle.In one claim recipients were implanted with either a single embryo, cardinal embryoin one uterine horn, or one embryo in for each one uterine horn. It is also possible tosplit embryos using a micro manipulator and implant each half to produceidentical twins. On the average about 16% of the cows implanted with two embryosproduced twins. When two embryos were implanted, and one was placed in each horn,conception rates were corresponding 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 race (Davis 302).Many producers see twinning as a possible progression in
