The effectiveness of Heatsynch protocol in dairy cows with abnormalities of reproductive organ

Abstract

Abstract The aim of this study was to determine the incidence of abnormalities of reproductive organs, and to determine the effectiveness of Heatsynchprotocol in dairy cows that suffered from abnormalities of reproductive organs. This study was conducted in smallholder dairy farms in Panette, Cendana Sub-district, Enrekang Regency and the study was conducted in two stages. The first stage; a total of 77 dairy cows were used to determine the incidence of reproductive organs abnormalities. The second stage; a total of 20 dairy cows that suffered from reproductive organs abnormalities were divided into two groups. The first 10 dairy cows were treated with Heatsynch, and the other 10 dairy cows were used as a negative control (without Heatsynch treatment). For positive control, 10 dairy cows that did not suffered from abnormalities of reproduction organs were used. The results of this study showed that the incidence of reproductive organs abnormalities was 36.4% and the highest of abnormalities was uterine disorders at 26%. The percentage of cows suffered from reproductive organs abnormalities that became pregnant after treated with Heatsynch was 60%, while none cows become pregnant without treatment. The average interval from calving to pregnancy in Heatsynch group was 512 days, and in control negative cows, none become pregnant up to 557 days after calving. It can be concluded that the incidence of abnormalities of reproductive organs in dairy cattle was still high. The Heatsynchprotocol can improve the abnormalities of the reproductive organs in the dairy cows and improve reproductive efficiency by increase the pregnancy rate and shortening calving interval.
