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), ...
How does stage of lactation and breeding worth affect milk solids production and production efficiency of grazing dairy cows?
(Taylor & Francis, 2019-03-18)
The study investigated the effect of stage of lactation and Breeding Worth (BW) index on estimated dry matter intake (DMI), milk solids (MS) production, energy use efficiency (EUE) and feed conversion efficiency (FCE) of ...
Consumption of sheep milk compared to cow milk can affect trabecular bone ultrastructure in a rat model
(The Royal Society of Chemistry, 2019-01-01)
Cow milk has a positive effect on bone health due to the effects of its protein, fat, lipid, vitamin, and mineral components. Sheep milk contains a unique composition of all of these components. However, to the best of our ...
Microbiological assessment of four probiotic feed supplements used by the dairy industry in New Zealand
(Taylor & Francis on behalf of the New Zealand Veterinary Association, 2013)
Since Metchnikoff’s publication ‘‘The Prolongation of Life’’ (Metchnikoff 1908) proposed the use of live bacteria to improve health, a precise definition of probiotics has yet to be formulated, however a widely held ...
Short communication: Grazing pattern of dairy cows that were selected for divergent residual feed intake as calves
(Elsevier on behalf of American Dairy Science Association (ADSA), 2015-09)
The aim of this study was to investigate and assess differences in the grazing pattern of 2 groups of mature dairy cows selected as calves for divergent residual feed intake (RFI). Sixteen Holstein-Friesian cows (471±31kg ...
Dairy cows increase ingestive mastication and reduce ruminative chewing when grazing chicory and plantain
(Elsevier on behalf of the American Dairy Science Association, 2013-12)
Although the nutritive value of chicory (Cichorium intybus L.) and plantain (Plantago lanceolata L.) has been thoroughly studied, little is known about the grazing behavior of cattle feeding on chicory and plantain swards. ...
Strategic grazing management towards sustainable intensification at tropical pasture-based dairy systems
(Elsevier, 2018-09-15)
Agricultural systems are responsible for environmental impacts that can be mitigated through the adoption of more sustainable principles. Our objective was to investigate the influence of two pre-grazing targets (95% and ...
Starter cultures and cattle feed manipulation enhance conjugated linoleic acid concentrations in Cheddar cheese
(American Dairy Science Association, Elsevier, and Federation of Animal Science Societies, 2013-04)
Conjugated linoleic acid (CLA) is a fatty acid (FA) that provides several health benefits to humans. The feeding of fish oil-supplemented diets to dairy cows has been extensively studied as a means to improve the CLA content ...
Technical note: Nitrogen isotopic fractionation can be used to predict nitrogen-use efficiency in dairy cows fed temperate pasture
(Oxford University Press on behalf of the American Society of Animal Science, 2013-12)
The objective of this study was to investigate the relationship between nitrogen isotopic fractionation (δ¹⁵N) and nitrogen-use efficiency (milk nitrogen/nitrogen intake; NUE) in pasture-fed dairy cows supplemented with ...
Timing of supplementation alters grazing behavior and milk production response in dairy cows
(Elsevier on behalf of the American Dairy Science Association, 2013-01)
Offering feed supplements to grazing dairy cows results in substitution of pasture; however, previous data indicate that the time at which concentrate supplements are offered might affect the level of substitution. These ...
