Role of plants in reducing nitrogen losses
(Royal Society of New Zealand, 2020-01-19)
We are pleased to present this special issue, ‘Role of plants in reducing nitrogen losses’. This issue brings together a group of studies that have focused on the role of crops and forages in mitigating nitrogen (N) losses ...
Can alternative forages substantially reduce N leaching? Findings from a review and associated modelling
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2019-11-13)
Nitrogen (N) leaching losses from grazed pasture systems pose a risk to the environment with mitigation strategies urgently required to achieve regulatory limits. There has been increased interest in alternative forages ...
Effect of vernalisation on the diurnal changes in fatty acid profile and nutrient composition of chicory in response to defoliation frequency
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2021-01-11)
The effect of defoliation frequency and severity on FA and nutrient composition of forage chicory (Cichorium intybus L.) before and after vernalisation were compared. Before vernalisation, the FA and nutrient components ...
Fodder beet to support early and late lactation milk production from pasture, is it worth the risk?
(Elsevier, 2021-02-01)
High yielding crops such as maize (Zea mays L.) and fodder beet (FB; Beta vulgaris L), are commonly used to extend lactation and increase animal productivity from pastoral dairy systems. Financial modelling to compare costs ...
Grazed chicory, plantain or ryegrass-white clover alters milk yield and fatty acid composition of late-lactating dairy cows
(CSIRO publishing, 2018-12-20)
The aim of the present research was to compare milk fatty acid composition of cows grazing perennial ryegrass-white clover pasture (RGWC), with that of cows grazing alternative forages of chicory or plantain. Fifty-four ...
Seasonal and diurnal changes in aucubin, catalpol and acteoside concentration of plantain herbage grown at high and low N fertiliser inputs
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018-08-02)
This experiment aimed to characterise the concentration of secondary compounds aucubin, catalpol and acteoside in plantain (Plantago lanceolata) herbage and determine if harvesting at different times or nitrogen (N) ...
Modelling feeding strategies to improve milk production, rumen function and discomfort of the early lactation dairy cow supplemented with fodder beet
(Cambridge University Press, 2020-05)
Feeding fodder beet (FB) to dairy cows in early lactation has recently been adopted by New Zealand dairy producers despite limited definition of feeding and grazing management practices that may prevent acute and sub-acute ...
Production, profit and nitrogen flows in irrigated dairy systems representing different industry development pathways: The Pastoral 21 experience in Canterbury
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-08-26)
Future development pathways for irrigated dairy farms in Canterbury operating under stricter nitrogen (N) loss limits were compared in two farmlets over four years. One represented the traditional pathway of intensification ...
Milk production does not benefit from mowing previously lax-grazed diverse pastures
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017)
Irrigated, diverse pastures were managed under normal (grazed to 3.5 cm) or lax (grazed to 5 cm allowing ryegrass seed head development) grazing intensity, with or without mowing (to 3.5 cm), in spring. On the subsequent ...
Milk yield and nitrogen excretion of dairy cows grazing binary and multispecies pastures
(John Wiley & Sons Ltd, 2017)
Three grazing experiments were carried out in late spring (early lactation), summer (mid-lactation) and autumn (late lactation) to compare the effects of perennial ryegrass cultivar or grass species, sown in binary or ...
