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 ...
Livestock in evolving foodscapes and thoughtscapes
(Frontiers Media S.A., 2020-07-14)
Humanity’s main societal and epistemic transitions also mirror changes in its approach to the food system. This particularly holds true for human–animal interactions and the consumption of animal source foods (red meat ...
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), ...
Effect of sward surface height and level of herbage depletion on bite features of cattle grazing Sorghum bicolor swards
(American Society of Animal Science, 2013-09)
To maximize herbage DMI, pregrazing sward surface height (SSH) and level of herbage depletion (HD) must be such that variables determining short-term herbage intake such as bite mass (BM) and bite rate (BR) are optimized. ...
Diurnal concentration of urinary nitrogen and rumen ammonia are modified by timing and mass of herbage allocation
(MDPI, 2019-11-13)
The objective of this work was to evaluate whether changes in time of herbage allocation and herbage mass (HM) (low (L) or medium (M)) modify the diurnal pattern of urinary nitrogen (N) concentration and ruminal ammonia ...
Plantain (Plantago lanceolata) reduces the environmental impact of farmed red deer (Cervus elaphus)
(Oxford University Press (OUP) on behalf of the American Society of Animal Science, 2020-07)
The objective of this study was to evaluate the effect of plantain (Plantago lanceolata L.) on water dynamics and balance, as well as nitrogen (N) excretion by red deer (Cervus elaphus L.) as a potential forage tool to ...
In vitro fermentation characteristics of ryegrass-white clover sward containing different proportions of chicory
(New Zealand Society of Animal Production, 2017)
Chicory (Cichorum intybus) is a deep-rooted grazeable forage used to overcome production and nutritive value shortfalls of perennial ryegrass (Loliun perenne) and white clover (Trifolium repens) swards during summer drought ...
Simulating the intake and nitrogen excretion from cows grazing forages fertilised with increasing rates of nitrogen
(New Zealand Society of Animal Production (Inc), 2018)
The dry matter intake (DMI), production, and urinary nitrogen (N) excretion of dairy cows grazing forage grown under increasing N fertiliser rates were explored using a mechanistic model of a grazing ruminant. The MINDY ...
Plantain: It is not only the dietary content, but also how we graze it…
(New Zealand Society of Animal Production (Inc), 2018)
A mechanistic and dynamic model of a grazing ruminant, MINDY, was used to explore the effect of both the proportion dietary inclusion of plantain (PL) and its grazing management, compared with ryegrass (RG), on urinary N ...
Functional traits, morphology, and herbage production of vernalised and non-vernalised chicory cv. Choice (Cichorium intybus l.) in response to defoliation frequency and height
(MDPI, 2020-05)
Chicory (Cichorium intybus L.) used in pastoral systems has the attributes required of a forage species to reduce animal urinary nitrogen loading to soil, increase milk production, and enhance milk fatty acid profile to ...
