Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
(Univ Sao Paolo, 2014-07-01)
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT ...
Estimates of genetic parameters for visual scores and their correlation with production and reproductive traits in Brahman cattle
(Sociedade Brasileira de Zootecnia, 2012-06-01)
The objective of this study was to evaluate the association of visual scores of body structure, precocity and muscularity with production (body weight at 18 months and average daily gain) and reproductive (scrotal ...
Genetic parameters estimates for milk, fat and protein yield analyzed by test day models for Murrah buffaloes in Brazil
(Pagepress Publ, 2007-01-01)
The objectives of this study were to estimate genetic parameters for test-day milk, fat and protein yields, in Murrah buffaloes. In this study 4,757 complete lactations of Murrah buffaloes were analyzed. The (co) variance ...

GENETIC PARAMETERS FOR GESTATION LENGTH AND PRE- AND POSTWEANING GROWTH TRAITS IN NELLORE CATTLE
(Inst Zootecnia, 2015-01-01)
The objective of this study was to estimate heritabilities and genetic and phenotypic correlations for gestation length as calf trait (GLcalf) and preweaning [birth weight (BW) and weights at 120 (W120) and 210 (W210) days] ...
Genetic parameters for milk yield, lactation length and calving intervals of murrah buffaloes from brazil
(2013-08-01)
The 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 ...

Genetic parameters for post-weaning visual scores and reproductive traits in Suffolk sheep
(2018-01-01)
The aim of this study was to estimate the coefficients of heritability and genetic correlations among visual scores (conformation, CPW; precocity, PPW; musculature, MPW ) and reproductive traits: age at first lambing (AFL) ...
