Abstract

The objective of this study was to investigate the population genetic structure and the effects of inbreeding on growth traits of Nellore breed animals from the Amazon biome. The database used for the analyzes contained records of 1,402,287 animals born between the years of 1950 and 2012 and weight ...

Abstract

Genetic diversity is one of the most important issues in studies on conservation of cattle breeds and endangered species. The objective of this study was to estimate the levels of genetic differentiation between locally adapted taurine (Bos taurus taurus) and zebu (Bos taurus indicus) breeds in...

Abstract

Inbreeding depression is caused by breeding between closely related individuals and can have a significant negative impact on cattle production. It can be estimated at the population level using pedigree analysis or molecular markers. Such estimations can then be used to better manage the genetic...

Abstract

We evaluated the population genetic structure of the Holstein breed in Brazil through pedigree analysis with the aim of supporting genetic management of extant herds. We used data from genealogical records of 204,511 animals in farms from south and southeast Brazil. Pedigree records between 1943...

Abstract

The objective of this study was to characterize the population genetic structure of the Gir breed in the Northeast of Brazil. The data used in this study were taken from pedigree information of 8,897 Gir animals between 1957 and 2007, obtained from the Brazilian Zebu Breeders Association (ABCZ)....

Abstract

The objective of the present study was to evaluate the genetic structure of Gyr cattle selected for milk production. Files of pedigree and production were composed of 27,610 animals. The ENDOG program was used for the calculation of individual inbreeding coefficient (F) and coefficient of average...

Abstract

The objective of this study was to evaluate the population structure of 91,579 Nellore cattle reared in the Northeast semi-arid, born between 1965 and 2011. We analyzed the pedigree and the estimation of population parameters based on the probability of gene origin. In the early years, a higher...

This work aimed to estimate the genetic (maternal and direct effects), phenotypic and environmental parameters and trends of the following features; time to reach 160 kg (D160) in the pre-weaning period and time to reach 240 kg (D240) in the post-weaning period for Nellore cattle born between 1980...

AbstractFull Text

The objective, in this study, was to estimate the genetic parameters and to evaluate both genetic and phenotypic trends for the weight at 205 (W205) and 365 (W365) days of age in Indubrazil cattle, born between 1976 and 2006, raised in Sergipe. The variance components and genetic values were...

Abstract

Reproductive isolation of cattle herds should have significant negative genetic consequences, including inbreeding depression and the loss of diversity through genetic drift. Cattle herds may also suffer detrimental effects on genetic variance caused by other demographic and population parameters...
