Multibreed genetic evaluation in bovines using simulated data employing a composite population
(2016-10-05)
Genetic evaluations in Brazil are performed within each animal breed; however, with the wide range of extant genetic groups in the country and the increased use of genetic crossing as a form of rapid meat production, more ...
Genetic and phenotypic trends for growth traits of buffaloes in Brazil
(Pagepress Publ, 2007-01-01)
The objectives this paper were to estimate genetic parameters and genetic and phenotypic trends of birth weight (BWT) and weights adjusted to 205 (WT205), 365 (WT365) and 550 (P550) days of age of beef buffaloes born from ...

Efeitos genéticos e ambientais sobre a idade à primeira concepção de fêmeas suínas
(Universidade Federal de Minas Gerais (UFMG), Escola de Veterinária, 2008-04-01)
The genetic and environmental factors that affect age at first conception (AFC) of gilts were evaluated, using 466 observations of Dalland animals (C-40). The software program MTDFREML was used to assess the genetic ...

Environmental and genetic factors affecting the weaning-estrus interval in sows
(Funpec-editora, 2011-01-01)
We examined the effects of environmental and genetic factors on the weaning-to-estrus interval (WEI) in sows. In order to perform the analyses of the environmental factors, 8104 observations of the 1st to the 6th WEI were ...
