Is the temperament of crossbred dairy cows related to milk cortisol and oxytocin concentrations, milk yield, and quality? Reactive dairy cows are more susceptible to stress, and this may result in negative effects on milk yield and quality. The aims of this study were to investigate the relationships between temperament... ... Repositório: BDPA Ano de publicação: 2023
Milk yield persistency in brazilian gyr cattle based on a random regression model. With the objective of evaluating measures of milk yield persistency, 27,000 test-day milk yield records from 3362 first lactations of Brazilian Gyr cows that calved between 1990 and 2007 were analyzed... ...

Estimation of genetic parameters for test-day milk yield in holstein cows using a random regression model. Test-day milk yield records of 11,023 first-parity Holstein cows were used to estimate genetic parameters for milk yield during different lactation periods. (Co)variance components were estimated usin... ... Repositório: BDPA Ano de publicação: 2005
Estimates of genetic and crossbreeding parameters for 305-day milk yield of Girolando cows. The objective of this work was to evaluate the effects of breed and heterosis on the estimates of genetic parameters of 305-day milk yield (305MY), by fitting milk yield data to the Wood, Mixed Log, M... ...
