A study was carried on performance of the Brown Swiss cattle with the objective of estimating adjustment factors, evaluate some environment and genetics factors that affect milk and fat yields and fat percentage, and estimate genetic parameters for this productive traits. It was appraised 11,189 lactations out of 5,382 Brown Swiss cows, from 1980 to 1999, originated from 201 herds, provided by milking record service accomplished by the Brown Swiss Cattle Breeder`s Association of Brazil. Productions were adjusted by a […]
