Influencia del microclima en el período parto-concepción en vacas Holstein Friesian dentro provincia del Tungurahua- Ecuador.

Abstract

The main objective of this research was to determine the effect of the environment on the calving- conception period in Holstein Friesian cows in the Province of Tungurahua, with this the productive and reproductive quality of the cows that are raised in the province will be improvised, and that if you have the desired results, you can extend the research to different provinces of Ecuador, all the tools that were used were included in an experimental explanatory scheme, since all the data was collected experimentally in the cattle herds and it was used to statistical tools to explain the data in detail. The population that was analyzed was represented by 330 animals of the Holstein Friesian breed, of which a representative sample of 40 randomly chosen cows was used. The results determined in the analysis of the correlation between temperature and other study variables that the correlation is significant at the 0.05 level (bilateral). Temperature and Relative Humidity, because the temperature-humidity index (THI) also has a significant effect on the rate of conception. It is concluded that to carry out a process of bovine reproduction under efficiency standards, it is important to know the behavioral physiology of the animal and thus effectively carry out the pregnant cycles of the female and her subsequent delivery process. Have the ability to become pregnant in the shortest possible time (natural mating) and through the evaluation of reproductive parameters, indicative of fertility. It is recommended to identify the most favorable times for the induced reproduction procedures, because as has been evidenced in this article, those times of high environmental temperature have negative effects on the reproductive parameters of the dairy herd.
