Genetic parameters for earnings in Quarter Horse
Authors: A.P.A. Silva, R.A. Curi, B. Langlois and J.A.II.V. Silva
In this study, we estimated the heritability (h2) of earnings in the Quarter Horse in order to evaluate the inclusion of this trait in breeding programs. Records from 14,754 races of 2443 horses from 1978-2009 were provided by Sorocaba Hippodrome, São Paulo, Brazil. All ancestors of the registered horses were included i.. Read More»

Selection and estimation of the heritability of sunflower (Helianthus annuus) pollen collection behavior in Apis mellifera colonies
Authors: Basualdo M, RodrÃ?Âguez EM, Bedascarrasbure E and De Jong D
We selected honey bee colonies (Apis mellifera L.) with a high tendency to collect sunflower pollen and estimated the heritability of this trait. The percentage of sunflower pollen collected by 74 colonies was evaluated. Five colonies that collected the highest percentages of sunflower pollen were selected. Nineteen colonies h.. Read More»

Genetic correlation between heifer pregnancy and scrotal circumference measured at 15 and 18 months of age in Nellore cattle
Authors: J.P. Eler, J.B.S. Ferraz, J.C.C. Balieiro, E.C. Mattos and G.B. Mour�£o
Data of pregnancy diagnosis from 24,945 Nellore heifers, raised under tropical conditions in Brazil and exposed to breeding at about 14 months of age, were analyzed simultaneously with 13,742 (analysis 1), 36,091 (analysis 2), 8,405 (analysis 3), and 8,405 (analysis 4) scrotal circumference (SC) records of contemporary young b..

Comparison of different models to estimate genetic parameters for carcass traits in a commercial broiler line
Authors: J.L.B.M. Grosso, J.C.C. Balieiro, J.P. Eler, J.B.S. Ferraz, E.C. Mattos and T. Michelan Filho
The effect of genetic and non-genetic factors for carcass, breast meat and leg weights, and yields of a commercial broiler line were investigated using the restricted maximum likelihood method, considering four different animal models, including or excluding maternal genetic effect with covariance between direct and maternal g..

Breeding of Acrocomia aculeata using genetic diversity parameters and correlations to select accessions based on vegetative, phenological, and reproductive characteristics
Authors: S.M. Coser, S.Y. Motoike, T.R. Corr�ªa, T.P. Pires and M.D.V. Resende
Macaw palm (Acrocomia aculeata) is a promising species for use in biofuel production, and establishing breeding programs is important for the development of commercial plantations. The aim of the present study was to analyze genetic diversity, verify correlations between traits, estimate genetic parameters, and select differen.. Read More»

Morphological evolution and heritability estimates for some biometric traits in the Murgese horse breed
Authors: C. Dario, D. Carnicella, M. Dario and G. Bufano
A data set concerning 1,816 subjects entered in the Italian Horse Registry from 1925 to 2002 was analyzed to investigate the morphological evolution of the Murgese horse and to obtain useful elements to enhance breeding practices. Three basic body measurements (height at withers, chest girth, and cannon bone circumference) wer.. Read More»

Estimation of genetic parameters and genetic changes for growth characteristics of Santa Ines sheep
Authors: E.L. Aguirre, E.C. Mattos, J.P. Eler, A.D. Barreto Neto and J.B. Ferraz
Studying genetic parameters and genetic changes in Santa Ines sheep is important, because it is the commonest breed in Brazil. This study obtained genetic data from 37,735 pedigree records of lambs over 12 years (2003-2014) from 33 flocks in 10 Brazilian States; 11,851 records of performance were available. (Co)variance components, genetic parameters and .. Read More»

Heritabilities and genetic correlations for reproductive traits in an F2 reciprocal cross chicken population
Authors: R.P. Savegnago, M.E. Buzanskas, B.N. Nunes, S.B. Ramos, M.C. Ledur, K. Nones and D.P. Munari
Studies estimating genetic parameters for reproductive traits in chickens can be useful for understanding and improvement of their genetic architecture. A total of 1276 observations of fertility (FERT), hatchability of fertile eggs (HFE) and hatchability of total eggs (HTE) were used to estimate the genetic and phenotypic para.. Read More»
