Environmental parameters affecting the concentration of iodine in New Zealand pasture
(American Society of Agronomy, Crop Science Society of America & Soil Science of America, 2019-08-21)
Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I ...
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 ...
Valuing conservation benefits of disease control in wildlife: A choice experiment approach to bovine tuberculosis management in New Zealand's native forests
(Elsevier, 2017-03-15)
We assess the non-monetary environmental benefits that accrue incidentally in New Zealand (NZ) from pest management conducted primarily to control an animal disease, bovine tuberculosis (TB). TB is an infectious disease ...
Detection of mastitis and its stage of progression by automatic milking systems using artificial neural networks
(Cambridge University Press, 2010-05)
Two types of artificial neural networks, multilayer perceptron (MLP) and self-organizing feature map (SOM) were used to detect mastitis by automatic milking systems (AMS) using a new mastitis indicator that combined two ...
Fractionation of arsenic in soil by a continuous-flow sequential extraction method
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2001)
Batch sequential extraction techniques for fractionating metals or metalloids in soils are time consuming and subject to several potential errors. The development of a continuous-flow sequential extraction method for soil ...
The performance of an efficient dairy system using a combination of nitrogen leaching mitigation strategies in a variable climate
(Elsevier, 2017-12-01)
An efficient dairy system, that implemented a combination of nitrogen (N) leaching mitigation strategies including lower N fertilizer input, standing cows off pasture for part of the day in autumn and winter (stand-off), ...
Dairy farm effluent effects on urine patch nitrous oxide and carbon dioxide emissions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Dairy farm effluent (DFE) comprises animal feces, urine, and wash-down water collected at the milking shed. This is collected daily during the milking season and sprayed onto grazed dairy pastures. Urine patches in grazed ...
Preparation, optimization and characterization of bovine lactoferrin‐loaded liposomes and solid lipid particles modified by hydrophilic polymers using factorial design
(John Wiley & Sons, Inc. on behalf of the American Peptide Society (APS), 2014-05)
Bioadhesive liposomes and solid lipid particles (SLPs) modified by pectin and chitosan for oral administration of bovine lactoferrin (bLf) were prepared using a 2⁴ full-factorial design to identify the key formulation ...
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), ...
