Genetic parameters for days to calving, calving data and calving success of experimental herds of Nelore cattle



Genetic parameters for days to calving, calving data and calving success of experimental herds of Nelore cattle



Boletim de Industria Animal 62(1): 1-7



Data from three experimental herds of Nelore cattle in Brazil were analysed to estimate genetic parameters for three fertility traits of cows: days to calving (DIAP), calving date (DATAP) and calving success (SP). The 7951 records of 1575 cows were obtained from 1978 to 2000 and up to 12 records by animal were available.
