AbstractFull Text

The genetic reserve of Uruguayan Creole cattle (UCC) consists of 575 animals, unselected and adapted to a natural environment. We analyze the genetic potential and diversity of the UCC genetic reserve by means of three major dairy genes and two microsatellites, in relation to its productive...

AbstractFull Text

Generic equations were derived using probability and transition matrices to track the flow of genes originating from a purebred or crossbred mating. Cumulative discounted expressions (CDE) were calculated for annual, replacement heifer, cull cow, birth, yearling, and slaughter traits using input...

AbstractFull Text

Records of 152 145 test-day (TD) milk yields, from 7,317 complete first lactations of Holstein cattle raised in Brazil were analysed. Estimate covariance functions for additive genetic and permanent environmental effects, as well as the genetic parameters for TD milk records using random regression ...

AbstractFull Text

Relationships among mature weight, maturing rate and longevity (age at disposal) were studied in 256 Holstein-Friesian cows born from 1992 to 2001 and raised in the dairy cattle production system of Embrapa Southeast Cattle, São Carlos, São Paulo, Brazil. The linear model included the fixed effects ...

AbstractFull Text

Individual inbreeding coefficients (F) were estimated for 27 610 animals of Gyr Dairy Cattle and distributed in 29 classes (CF). Despite the low values of the average F (2.82%), 60% of the population is inbred, a percent considered worrying. Records of 24 405 lactations from 8,879 cows were used to ...

AbstractFull Text

The objective of this research was to estimate the values of the components of (co)variances, herdability and genetic and phenotypic correlations for the traits milk yield at 210 days of lactation (PL210) and milk yield at 305 days of lactation (PL305) on animals Caracu breed. The data used were...

AbstractFull Text

This paper deals with the effects of hair coat on the sweating rate in Brazilian Braford cows, together with estimation of genetic correlation and heritability of these traits. Data were collected from heifers and cows in a commercial herd managed under extensive system. Sweating rate (SR), hair...

AbstractFull Text

Records of 6604 test day to milk yield were analysed in the first lactation of 876 cows of Girolando breed, obtained from 1989 to 2001, from the Girolando's Brazilian Association. Seven types of measurement were analysed for lactation persistence using the genetic values of milk production of the...
