AbstractFull Text

Milk production has high economic importance in dairy cattle production systems, which justifies its inclusion in genetic breeding programs. The objective of this study was to evaluate the genetic and phenotypic trends of dairy traits in Gyr (167 lactations) and Guzerá (148 lactations) breeds in...

Abstract

Brazilian Red Sindhi was originated from a very small number of founders and showed a consistent growth during the last three decades. One relevant herd was kept without proper birth recording and the reconstruction of parentage was possible for this herd through the use of a panel with 3894 SNP...

AbstractFull Text

The aim of this study was to explore the pattern of genetic lactation curves of Guzerá cattle using cluster analysis. Test-day milk yields of 5,274 first-lactation Guzerá cows were recorded in a progeny test. A total of 34,193 monthly records were analyzed with a random regression animal model...

Abstract

Data of 13,406 records from 7,153 lactating Gyr dairy cows whose calving occurred from 1960 to 2008 were used. The purpose of this study was to estimate gains or losses in milk production and economic values attributed to the variation in the calving interval (IP). The average of milk production...

Abstract

The main objective of this study was to verify genetic trends for milk production (MY305) and age at first calving (AFC). Were also considered levels of inbreeding practiced in the Brazilian dual-purpose Guzerá population (TPOP) comparing it with the same parameters estimated for two...
