| Descripción : | The reproductive indexes are a set of indicators within the reproduction that allow us to evaluate the reproductive behavior of a group of animals, fertility is one of the indicators that are most affected by environmental or nutritional conditions generating stress and negative energy balances causing prolonged anestro, embryonic deaths and bad ovulations. This study was a retrospective analysis of the influence of climatic factors on fertility indexes was made through reproduction records of the Hacienda Miraflores Alto (Tambillo- Ecuador) for the period 2013-2015 and the climatic data of the INAMHI of the same period to determinate if the climatic factors affect or not the fertility of the bovine herd of the Hacienda Miraflores Alto. The sample of the study was 210 animals which were evaluated during three consecutive years and it was determined which are the most favorable times to increase the breeding percentage of the herd, we used a sample of 210 bovine females was obtained In this study we used measures of central tendency, Tukey, analysis of variance (ANOVA) and Pearson correlation, additionally the statistical program SPSS 23 was applied with 95 percent confidence in which, by ANOVA we determinate that heliofania and temperature did not have significant difference of 5 percent, where P was 0.003 percent of temperature and precipitation had P value of 0.692 (p 0.05). By the other side, we obtained results from a) humidity and services by conception, b) humidity with the interval between births and c) interval of deliveries with services by conception had a moderate correlation and the rest was minimal. In conclusion, with all the results obtained, the alternative hypothesis was accepted for the variable temperature, heliofania, precipitation and humidity, it influenced on total inseminations, effective inseminations, open days, services by conception, aphthous and embryonic reabsorption. |
