Eutrophication and climate change impacts of a case study of New Zealand beef to the European market
(Elsevier, 2020-03-25)
Objective: Beef production in the Lake Taupō region of New Zealand (NZ) is regulated for nitrogen (N) leaching. The objectives of this study were to 1) evaluate the implications of nitrogen emission limitations on ...
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 ...
Increased yearling weight as a proportion of 21-month weight was associated with increased milk production in dairy heifers
(Taylor & Francis on behalf of New Zealand Veterinary Association, 2020-05-25)
Aims: To examine the relationship between liveweight (LWT) at 12 months as a proportion of LWT at 21 months of age (LWT(12/21)%) and first lactation and cumulative 3-year milk production in dairy heifers in New Zealand.
Methods: ...
Sous-vide cooking improves the quality and in-vitro digestibility of Semitendinosus from culled dairy cows
(Elsevier, 2020-01)
Effect of sous-vide processing was evaluated on in-vitro simulated protein digestion, myofibrillar protein profile, lipid oxidation and physicochemical properties of cold-boned beef Semitendinosus. Sous-vide processed [T1, ...
The application of pulsed electric field as a sodium reducing strategy for meat products
(Elsevier, 2020-02-15)
This study investigated the potential of pulsed electric field (PEF) as a sodium-reduction strategy for processed meat. Beef jerky was used as a model and prepared using different levels of NaCl, viz. 2.0% (control), 1.2% ...
Production intensification and animal health expenditure on dairy farms in New Zealand
(American Dairy Science Association, 2020-02)
Although previous studies have investigated the ef-fects of production intensification on farm economic performance and production efficiency in the dairy sector, knowledge is currently lacking on how ...
Proteomics and metabolomics in cow fertility: A systematic review
(BioScientifica on behalf of the Society for Reproduction and Fertility, 2020-11-01)
Cow subfertility is a multi-factorial problem in many countries which is only starting to be unravelled. Molecular biology can provide a substantial source of insight into its causes and potential solutions, particularly ...
Analysis of adoption trends of in-parlor technologies over a 10-year period for labor saving and data capture on pasture-based dairy farms
(Elsevier on behalf of the American Dairy Association ®, 2020-11-06)
The use of precision technology is increasingly seen as an option to improve productivity, animal welfare, resource use efficiency, and workplace features on dairy farms. There is limited research related to longitudinal ...
Novel viscoelastic gelling agent with unique physico-chemical properties
(Elsevier, 2021-05-15)
A novel innovative viscoelastic gelling agent (novel gel, NG) has been developed by combining citric acid (CA) and disodium 5-guanylate (DG). NG has the potential to replace other gelling agents such as gelatine, which has ...
