Inclusão da epistasia em modelo de avaliação genética de bovinos de corte compostos
(Universidade Federal de Minas Gerais, Escola de Veterinária, 2011)
Dados de bovinos compostos foram analisados para avaliar o efeito da epistasia nos modelos de avaliação genética. As características analisadas foram os pesos aos 205 (P205) e 390 dias (P390) e perímetro escrotal aos 390 ...
Genetic-quantitative analysis for reproductive traits in Nellor cattle selected for sexual precocity
(Csiro Publishing, 2020-01-01)
Context. The selection of animals for sexual precocity and reproductive efficiency is a trend to reduce the production cycle, promote higher economic viability to the system, increase selection intensity and higher genetic ...
Anatomopathological Evaluation of Young Bulls (Bos taurus) Testicles Submitted to Immunocastration
(Universidade Federal do Rio Grande do Sul, 2019)
Effect of IGF1, GH, and PIT1 markers on the genetic parameters of growth and reproduction traits in Canchim cattle
(Springer, 2015-01-01)
The availability of dense genomic information has increased genome-wide association studies for the bovine species; however research to assess the effect of single genes on production traits is still important to elucidate ...
Selection criteria for feed efficiency-related traits and their association with growth, reproductive and carcass traits in Nelore cattle
(2021-01-01)
Context: Livestock feed costs have a higher impact on the profitability of beef production systems and are directly related to feed efficiency. However, these traits are hard and have high costs to measure, reducing the ...
Estudo de interação genótipo x ambiente para peso e perímetro escrotal à desmama na raça Canchim
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEv, 2007-02-26)
In beef cattle genetic evaluation programs, the existence of genotype x environment
interaction is of special interest when merit of the animals depends on the environment they
are evaluated, that is, when a genotype is ...
