- Abstract
For the adequacy of the milk activity, it is of fundamental importance to determine a more profitable production with the intensive use of the area for the production of forage, a control of the reproductive efficiency and lower age at the first calving. This study aimed to quantify the occurrence of abortions and stillbirths in dairy cows in the São Caetano and Chapadão farms in the town of Morrinhos-Go. The monitoring of reproductive failures was done daily for six years, from 2008 to 2013. The technician responsible for the sector recorded the occurrences in the agricultural bookkeeping agendas of the farms. In 2014, the data were retrieved from the farm files and released on a digital spreadsheet. For the statistical analysis, the variables of the abortion and stillbirth rates (%) were submitted to analysis of variance, at a significance level of 5%, having as cause of variation the year. The observed abortion rate was 3.93% and the stillbirth rate 2.89% both considered low. There was no significant difference between the years followed (p <0.05) in both. Stillbirth and abortion are not considered problems in the farms studied, due to the good practices of control and management.
