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 ...
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: ...
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 ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to
surface water quality in many parts of New Zealand and Australia.
Farming, especially pasture-based dairying, can be a source of P
loss, but preventing it ...
Combining restricted grazing and nitrification inhibitors to reduce nitrogen leaching on New Zealand dairy farms
(Crop Science Society of America, Soil Science Society of America and American Society of Agronomy, 2017-01-12)
Intensification of pastoral dairy systems often means more
nitrogen (N) leaching. A number of mitigation strategies have
been proposed to reduce or reverse this trend. The main strategies
focus ...
Microbiological assessment of four probiotic feed supplements used by the dairy industry in New Zealand
(Taylor & Francis on behalf of the New Zealand Veterinary Association, 2013)
Since Metchnikoff’s publication ‘‘The Prolongation of Life’’ (Metchnikoff 1908) proposed the use of live bacteria to improve health, a precise definition of probiotics has yet to be formulated, however a widely held ...
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 ...
Short communication: The relationship between farm debt and dairy productivity and profitability in New Zealand
(Elsevier and Federation of Animal Science Societies (FASS) on behalf of the American Dairy Science Association, 2020-09)
For a variety of reasons, dairy sector indebtedness has increased in recent years. However, it is not clear whether increased debt boosts or damages the economic performance of dairy farms. This paper provides empirical ...
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 ...
