Screening for diets that reduce urinary nitrogen excretion and methane emissions while maintaining or increasing production by dairy cows
Farmers face complex decisions at the time to feed animals, trying to achieve production goals while contemplating social and environmental constraints. Our purpose was to facilitate such decision making for pastoral dairy ...
Diurnal patterns of urination and drinking by grazing ruminants: A development in a mechanistic model of a grazing ruminant, MINDY
(Cambridge University Press, 2018-01)
Measurement of water consumption and urinary nitrogen (UN) excretion of individual grazing ruminants is difficult, time-consuming and expensive. Therefore, prediction and modelling are critical for research to improve N ...
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 ...
Characteristics of boli formed by dairy cows upon ingestion of fresh ryegrass, lucerne or chicory
(Cambridge University Press on behalf of The Animal Consortium, 2019-06)
This study examined the comminution of fresh herbage, subsequent nutrient release, and the characteristics of swallowed boli from three physically and chemically contrasting forages during ingestive mastication by dairy ...
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 ...
A comparison of methods for estimating forage intake, digestibility, and fecal output in red deer (Cervus elaphus)
(Oxford University Press (OUP) on behalf of the American Society of Animal Science, 2020-03)
The objective of this experiment was to determine appropriate methods for estimating fecal output, digestibility, and intake in red deer (Cervus elaphus). Dry matter intake (DMI), digestibility, and fecal output were ...
