Genetic association between longevity and linear type traits of Holstein cows
Kern, Elisandra Lurdes; Cobuci, Jaime Araújo; Costa, Claudio Napolis; Pimentel, Concepta Margaret McManus; Braccini Neto, José (2015) [Artigo de periódico]Longevity is a desirable trait in the dairy industry because of its relationship to profitability. The aim of this study was to estimate genetic parameters for longevity measurements related to productive life, or life in ... -
Genetic associations between reproductive and linear-type traits of Holstein cows in Brazil
Almeida, Tatiana Prestes de; Kern, Elisandra Lurdes; Daltro, Darlene dos Santos; Braccini Neto, José; Pimentel, Concepta Margaret McManus; Thaler Neto, André; Cobuci, Jaime Araújo (2017) [Artigo de periódico]This study aimed to estimate heritability, genetic, and residual correlations between reproductive traits such as age at first calving, calving interval, dry period, and first service period and linear type traits measured ... -
Heterosis in the lactation curves of Girolando cows with emphasis on variations of the individual curves
Daltro, Darlene dos Santos; Padilha, Alessandro Haiduck; Silva, Marcos Vinicius Gualberto Barbosa; Kern, Elisandra Lurdes; Santos, Diego Charles de Almeida; Panetto, João Cláudio do Carmo; Gama, Luís Telo da; Cobuci, Jaime Araújo (2019) [Artigo de periódico] -
Phenotypic relationships between type traits and productive life using a piecewise Weibull proportional hazard model
Kern, Elisandra Lurdes; Cobuci, Jaime Araújo; Costa, Claudio Napolis; Ducrocq, Vincent (2018) [Artigo de periódico]Longevity is an important trait due to its relationship with profitability. Type traits have been used as indirect predictors for productive life. The objective of this study was to evaluate the relationship of 20 type ...
