Resumen
The hormone treatments proposed in the following research will improve the
fertility in cows; since the reproduction has been affecting the economic
development on farms in the last years; the presence of physiological problems
due to disorders in the hormonal system, need appropriate treatments to regulate
the cow reproduction, and to get a calf per year. For this, different estrus
synchronization methods have been studied, such as: Ovsynch, Presynch, and
Cosynch with which the reproductive cycle normalization of cows is achieved by
improving their fertility. Bautista, E. (2008), Indicates that the use of Ovsynch
method permits to register an 83% of pregnancy, thus it is concluded that the
hormonal disorders which cause fertility problems are controlled with the use of
synchronization programs which not only improve the fertility but it can be used to
program births in higher reproduction periods, moreover it would be possible to
have groups of homogenous calves.
