Effect of lactation length adjustment procedures on genetic parameter estimates for buffalo milk yield
(Genetics and Molecular Biology, 2011-01-01) [Artigo]
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 parameter estimates for live weight and daily live weight gain obtained for Nellore bulls in a test station using different models
(Livestock Science, 2012-03-01) [Artigo]
The objective of this study was to estimate (co)variance components and genetic parameters for live weight (LW) and daily live weight gain (LWG) of Nellore bulls in a test station using multi-trait and random regression ...
Genetic parameters for test-day yield of milk, fat and protein in buffaloes estimated by random regression models
(Journal of Dairy Research, 2012-08-01) [Artigo]
The test-day yields of milk, fat and protein were analysed from 1433 first lactations of buffaloes of the Murrah breed, daughters of 113 sires from 12 herds in the state of São Paulo, Brazil, born between 1985 and 2007. ...
Milk fatty acid characterization and genetic parameter estimates for milk conjugated linoleic acid in buffaloes
(Journal of Dairy Research, 2011-05-01) [Artigo]
The objectives of this study were to analyse buffalo milk fat composition, to verify the activity of Delta (9)-desaturase enzyme in the mammary gland, as well as to estimate additive genetic variances for milk, fat and ...
