Estimation of Genetic Parameters for Milk Production Traits Using a Random Regression Test-day Model in Holstein Cows in Korea
Random Regression Model Heritability Test-day Milk Production Traits Heterogeneity
2016/4/29
This study was conducted to compare three models: two random regression models with and without considering heterogeneity in the residual variances and a lactation model (LM) for evaluating the geneti...

2016/4/25
The objective of this study was to assess the association of polymorphisms in 觀-cn, ??lg, ??lg 5??flanking region, CSN1S2, and IGFBP-3 genes with milk production traits and mastitis-related traits in ...
Effect of Butyrophilin Gene Polymorphism on Milk Quality Traits in Crossbred Cattle
ilin Crossbred Cattle Polymorphism Milk Quality Traits
2016/4/21
A genetic polymorphism study on butyrophilin gene was carried out to explore variability of this gene and to estimate effects of such variability on milk quality traits in crossbred cattle. Polymorphi...
Effects of Some Management Factors on Milk Production in First-calf Heifers
Dairy Cow Milk Performance Rearing Housing Sire Lineage Season of Birth and Calving
2016/4/21

Relationship between the Polymorphisms of 5''Regulation Region of Prolactin Gene and Milk Traits in Chinese Holstein Dairy Cows
Prolactin (PRL) PCR-RFLP PCR-SSCP Milk Traits
2016/4/21
Prolactin (PRL) plays an important role in promoting mammalian mammary gland development, and milk production during lactation. Therefore the PRL gene was chosen as a candidate gene for milk traits in...
