Consideración de diferentes aspectos de la Inseminación artificial (IA) en bovinos

Abstract

Given that high demand for animal protein is expected to the world in a few years, we need to take extra measures to improve the efficiency of the sources of supply of these proteins, particularly meat and milk. Biotechnologies of animal reproduction acquire a prime importance in these improvements for their productive impact. As part of these biotechnologies, timed artificial insemination (TAI) has grown exponentially in the Mercosur, which has markedly increased in the proportion of females inseminated in relation to these that are able to be breeding. This has also been marked in beef cattle where almost 80% of the females are inseminated. This improves not only the genetic level of the herds but also contributes directly and significantly in the productivity of these herds. This strong increase in demand has also led to an increase in the quality of the treatments carried out, have better defined the moments to do insemination and because of this, a great increase in fertility of the cows inseminated after these treatments. The other biotechnology that has changing the level of efficiency of cattle production is the use of sexed semen. This is of particular interest in dairy cattle and its great increase in recent years has allowed the improvement in several aspects what has made their increase daily. In short, the recent massive incorporation of new technologies and management systems (semen sexing, handling time of AI, TAI) have promoted and contributed to its expansion both in beef and milk cattle allowing to significantly improving productivity.
