Genetic parameter estimation for visual score and ponderal development traits in Nellore cattle
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2015-08-01)
The aim of this study was to evaluate the genetic association between visual scores of structure, finishing precocity and muscling with weight at 18 months, daily weight gain and scrotal circumference in male Nellore. A ...
Genetic associations of conformation, finishing precocity and muscling visual scores with mature weight in Nelore cattle
(Elsevier B.V., 2011-02-01)
Were estimate (co)variance and genetic associations between conformation, finishing precocity and muscling visual scores measured at weaning (SCW, SFW and SMW, respectively) and yearling (SCY. SFY and SMY, respectively) ...
Finishing precocity visual score and genetic associations with growth traits in Angus beef cattle
(Funpec-editora, 2014-01-01)
Finishing precocity visual score selection was adopted to estimate the time from birth to reach slaughter age. This study estimated (co) variance components and genetic correlations for the finishing precocity score at ...
Genetic associations of visual scores with subsequent rebreeding and days to first calving in Nellore cattle
(Wiley-Blackwell, 2012-12-01)
Records of Nellore animals born from 1990 to 2006 were used to estimate genetic correlations of visual scores at yearling (conformation, C; finishing precocity, P; and muscling, M) with primiparous subsequent rebreeding ...
Genetic associations of sexual precocity with growth traits and visual scores of conformation, finishing, and muscling in Nelore cattle
(Amer Soc Animal Science, 2009-05-01)
The objective of this study was to determine the possible use of heifer pregnancy at 16 mo as a selection criterion and its possible genetic associations with hip height, yearling weight, and visual scores of conformation, ...
