Effects of social dominance on milk production and grazing behaviour of lactating dairy cows : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
In this study, three experiments were conducted to determine factors influencing social dominance in lactating, grazing dairy cows. Additionally, we investigated the effect of separating cows, based on social dominance, ...
Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Regular estimates of herbage mass can improve profitability of pasture-based dairy systems
(CSIRO Publishing, 2018-01-05)
Paddock selection is an important component of grazing management and is based on either an estimate of herbage mass, or the interval since last grazing for each paddock. Obtaining estimates of herbage mass to guide grazing ...
Potential inhibition of urine patch nitrous oxide emissions by Plantago lanceolata and its metabolite aucubin
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017-12-12)
Plantain (Plantago lanceolata L.), a forage used in grazed pastures, contains active secondary metabolites that could potentially inhibit nitrification, a key step in nitrous oxide (N₂O) production from grazing ruminant ...
Implications of grass-clover interactions in dairy pastures for forage indexing systems. 4. Canterbury
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018)
This paper describes how the core treatments in the national experimental design (all combinations of with/without clover and high/low nitrogen (N)) were implemented at an irrigated Canterbury site and monitored for three ...
Quantifying contaminant losses to water from pastoral land uses in New Zealand III. What could be achieved by 2035?
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-11-11)
To meet the water quality outcomes sought by catchment communities and regulators, the losses of nitrogen (N), phosphorus (P) and sediment from dairy and sheep/beef farms must be reduced across many catchments. We conducted ...
Variation in PLIN2 and its association with milk traits and milk fat composition in dairy cows
(Cambridge University Press, 2021-03-30)
The current study investigated associations between variation in the bovine perilipin-2 gene (PLIN2) and milk traits (milk fat content, milk protein content, milk yield and milk fatty acid (FA) component levels) in 409 New ...
Animal and forage responses on lucerne (Medicago sativa L.) pastures under contrasting grazing managements in a temperate climate
(Wiley on behalf of the British Grassland Society and the European Grassland Federation, 2020-06)
This study determined the impact of a change in grazing system on beef production from lucerne pastures in Argentina. One system (T500) used the traditional recommendation to commence grazing in spring when lucerne was ...
Scenario analysis to determine possible, plausible futures for the New Zealand dairy industry
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017)
New Zealand accounts for just 3% of global milk production, yet it is the largest global trader of milk across borders. In contrast to other milk-producing countries, less than 5% of New Zealand milk is consumed within the ...
Liveweight production, dry matter yield and seasonal composition from dryland lucerne and lucerne/grass mixes over five years
(Taylor and Francis on behalf of the Royal Society of New Zealand, 2019-07-29)
Liveweight production, dry matter yield and botanical composition of three lucerne based pastures (lucerne monoculture, lucerne/brome, lucerne/cocksfoot) were quantified for five years from a grazed, dryland experiment at ...
