Analysis of genetic correlations of hip height with selection indices and mature weight in Nelore cattle
(2013-01-25)
Body size is directly related to the productive and reproductive performance of beef cattle raised under free-range conditions. In an attempt to better plan selection criteria, avoiding extremes in body size, this study ...
Genetic parameters for body weight, carcass chemical composition and yield in a broiler-layer cross developed for QTL mapping
(Sociedade Brasileira de Genética, 2011-01-01)
The objective of this study was to estimate genetic and phenotypic correlations of body weight at 6 weeks of age (BW6), as well as final carcass yield, and moisture, protein, fat and ash contents, using data from 3,422 F2 ...
Genetic parameters for milk yield, age at first calving and interval between first and second calving in milk Murrah buffaloes
(2010-02-01)
In the present study, data of 1,578 first lactation females, calving from 1985 to 2006 were analysed with the purpose of estimating genetic parameters for milk yield (MY), age at first calving (AFC) and interval between ...
Effect of lactation length adjustment procedures on genetic parameter estimates for buffalo milk yield
(Sociedade Brasileira de Genética, 2011-01-01)
The objectives of this study were to estimate the genetic parameters for milk yield unadjusted and adjusted for days in milk and, subsequently, to assess the influence of adjusting for days in milk on sire rank. Complete ...
Genetic parameters for Piscirickettsia salmonis resistance, sea lice (Caligus rogercresseyi) susceptibility and harvest weight in rainbow trout (Oncorhynchus mykiss)
(Elsevier B.V., 2019)
Piscirickettsiosis caused by the intracellular bacterium Piscirickettsia salmonis and caligidosis produced by the ectoparasite Caligus rogercresseyi, are important diseases which generate great economic losses in salmonid ...
Genetic analysis of morphological and functional traits in Campolina horses using Bayesian multi-trait model
(2018-10-01)
In general, is said that functional traits have a positive genetic correlation with conformation in horses but, this hypothesis has never been investigated in the Brazilian Campolina breed. We aimed to estimate genetic ...
Genetic composition of Chilean aboriginal populations: HLA and other genetic marker variation
(1996)
Phenotypes and gene frequencies for eight genetic systems are presented for five Chilean Indian tribes. Results agree with the pattern expected for Andean Indians. Genetic distances and dendrograms were obtained separately ...
