    Consideración de diferentes aspectos de la Inseminación artificial (IA) en bovinos
    (Universidad de Cuenca, 2015) Decuadro-Hansen, Gustave; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca
    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.

    Impacto de los forrajes conservados sobre los sistemas de cria vacuna
    (Universidad de Cuenca, 2015) Arroquy, José Ignacio; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    In grazing systems, seasonal and inter-annual forage deficit and surplus management throughout the use of forage conservation has an important impact on pasture management and utilization, and consequently on animal performance and livestock system. This paper reports on the yield and quality of different preserved forage sources like silage or hay. Are also discussed the expected animal response with regards to harvest time and storage system (hay vs. silage). Thereby, special emphasis is given to the critical points that guarantee achieving high quality of conserved forages and the utilization of hay or silage as supplement under grazing, as well as for growing and finishing diets in feed yard systems. Finally, the paper highlights the normal nutritional deficiencies in conserved forage and discusses possible correction strategies. Even though it is well known that forage conservation - silage and hay - is a powerful tool for the intensification of livestock production systems, there are key aspects to be considered that guarantee a food reserve of high quality and take advantage of the reserves in the entire system, such as the forage production, harvest time, conservation method and utilization.
