Body weight of dairy heifers is positively associated with reproduction and stayability
(American Dairy Science Association, 2020-02-26)
This study investigated the relationships between body weight (BW) and stayability, and BW and calving pattern, of 189,936 New Zealand dairy heifers. Heifers were classified into 5 breed groups: Holstein-Friesian (F), ...
Effects of FABP4 variation on milk fatty-acid composition for dairy cattle grazed on pasture in late lactation
(Cambridge University Press on behalf of the Hannah Dairy Research Foundation, 2020-01-31)
This research communication describes associations between variation in the fatty acid binding protein 4 gene (FABP4) and milk fat composition in New Zealand Holstein-Friesian × Jersey cross dairy cows. After correcting ...
Variation in the toll-like receptor 4 (TLR4) gene affects milk traits in dairy cows
(Cambridge University Press on behalf of the Institute of Food Research and the Hannah Research Institute, 2017-11)
The objective of this Research Communication was to use polymerase chain reaction-single stranded conformational polymorphism (PCR-SSCP) analysis to investigate a region of the bovine TLR4 gene (TLR4) in pasture-fed New ...
Nitrogen partitioning and milk production of dairy cows grazing simple and diverse pastures
(Elsevier on behalf of the American Dairy Science Association, 2013-01)
Research was conducted to examine the effects of a diverse pasture mix on dry matter intake, milk yield, and N partitioning of lactating dairy cows. A pasture containing only ryegrass and white clover (RG), or high ...
Haplotypic variation in the UCP1 gene is associated with milk traits in dairy cows
(American Dairy Science Association, 2016-10-03)
Uncoupling protein-1 (UCP1) plays a role in the regulation of body temperature, metabolic rate and energy expenditure in animals. While variation in UCP1 and its phenotypic effect has been investigated in humans and sheep, ...
