Productive and reproductive traits in Murrah breed from Brazil
(Int Buffalo Information Ctr, 2013-01-01)
Major objective of this study was to estimate heritability and genetic correlations between milk yield (MY) and calving interval (CI) and lactation length (LL) in Murrah buffaloes using Bayesian inference. The database ...
Estimates of genetic parameters and genetic trends for reproductive traits and weaning weight in Tabapua cattle
(Amer Soc Animal Science, 2015-11-01)
The Tabapua breed is a beef cattle Brazilian breed known for its sexual precocity and desirable characteristics for tropical conditions. However, this is a newly formed breed and few studies have been conducted regarding ...
Genetic correlation of traits measured by ultrasound at yearling and 18 months of age in Nellore beef cattle
The objective of this study was to estimate genetic parameters for carcass traits measured by ultrasound at yearling (Y) and 18 months of age (post-yearling, PY) in order to identify the most appropriate age for the ...
Buffalo milk production in brazil and colombia: Genotype by environment interaction
The objective of this study was to determine whether there is a genotype by environment interaction (GxE) for dairy buffaloes in Brazil and Colombia. The (co)variance components were estimated by using a bi-trait repeatability ...
Genetic Parameters for Productive and Reproductive Traits for Milk Buffalo in Brazil
(Int Buffalo Information Ctr, 2014)
Genetic parameters for linear type traits and milk, fat, and protein production in holstein cows in Brazil.
(Asian-Australasian Journal of Animal Sciences (AJAS), v. 28, n. 4, p. 476-484, 2015., 2015)
Evaluation of mature cow weight: Genetic correlations with traits used in selection indices, correlated responses, and genetic trends in Nelore cattle
Genetic correlations of selection indices and the traits considered in these indices with mature weight (MW) of Nelore females and correlated responses were estimated to determine whether current selection practices will ...
Phenotypic, genetic and environmental parameters for traits related to femur bone integrity and body weight at 42 days of age in a broiler population
(Poultry Science Association Inc., 2015-11-01)
Intense selection among broilers, especially for performance and carcass traits, currently favors locomotion problems and bone resistance. Conducting studies relating to development and growth of bone tissue in broilers ...
