Abstract

We determined some reproductive characteristics of a dairy cattle herd Figueredo mestizo farm in the town of Coromandel, Minas Gerais, Brazil. We used the SAS program in order to carry out the descriptive study of the gestation period (GP), calving interval (CI) and days open (DO) in crossbred dairy cows. The GP averaged 273.57 days (9.11 months) with a standard deviation of 5.47 days (0.18 months), being the most frequent value of 271 days (9.06 months), with a coefficient of variation of 0, 02% in 111 observed data. The mean CI was 470.75 (15.69 months) with a standard deviation of 159.76 days (5.32 months) being the most frequent value of 385 days (12.83 months), with a coefficient of variation of 0, 34% in 75 notes processed. DO The average was 197.54 days (6.58 months) with a standard deviation of 163.92 days (5.44 months), being the most frequent value of 60 days (2 months), with a coefficient of variation of 0.83% in 102 records processed. The calving interval and days open showed up the dairy farm is considered appropriate to efficiently and economically
