Supplementing grape marc to cows fed a pasture-based diet as a method to alter nitrogen partitioning and excretion
(Elsevier on behalf of the American Dairy Science Association, 2012-02)
The inclusion of the grape marc into livestock rations provides an opportunity not only to use a waste byproduct resourcefully, but also to induce beneficial metabolic changes in animals. Grape marc contains condensed ...
Effect of pasture allowance and species diversity on rumen degradability and short-term grazing intake
Pasture allowance and rumen degradation rates have been shown to affect herbage intake and nutrient supply of lactating dairy cows, which ultimately influence milk production. The objective of this study was to compare the ...
Sulphur and lime response of four adventive annual clovers grown in a New Zealand high country soil under glasshouse conditions
(Taylor and Francis on behalf of the Royal Society of New Zealand, 2012-03)
Adventive annual clovers play a critical role in nitrogen (N) cycling and feed quality in extensive summer-dry hill country, where traditionally sown white and subterranean clovers often fail to persist. However, very ...
Effects of N fertilisation, leaf appearance and time of day on N fractionation and chemical composition of Lolium perenne cultivars in spring
(Elsevier B.V., 2012-05-11)
New Zealand dairy systems are based on Lolium perenne pastures with low nitrogen use efficiency (NUE) and high urinary N losses. Modelling attempts to provide solutions to improve NUE are limited due to lack of data on ...
Effect of ploidy and pasture mass on milk production and nitrogen use efficiency in late summer
Pre grazing mass and ploidy of perennial ryegrass pastures were investigated as immediate strategies that could be used to manipulate dry matter intake (DMI), milk production and nitrogen use efficiency (NUE) by reducing ...
Prediction of urinary output from pasture-fed dairy cows
Prediction equations using easily acquired measurements could offer an estimate of urinary nitrogen output (UNO), therein helping to refine nutrient management on dairy farms. However, there is little evidence regarding ...
