Methane and carbon dioxide emissions from lactating dairy cows grazing mature ryegrass/white clover or a diverse pasture comprising ryegrass, legumes and herbs
(CSIRO Publishing, 2018-06-29)
There is a growing interest in forage mixtures (Diverse pasture; e.g. containing grasses, legumes and herbs), especially those with a greater tolerance of dry conditions and a decreased nitrogen (N) content (reducing N ...
Development of an improved representation of rumen digesta outflow in a mechanistic and dynamic model of a dairy cow, Molly
© 2015 Elsevier B.V. Accurate predictions of outflow of digesta from the rumen are critical for improving modeling of feed intake, rumen function and fermentation patterns of ruminants. The main objective of this work was ...
Feeding diets with fodder beet decreased methane emissions from dry and lactating dairy cows in grazing systems
(CSIRO Publishing, 2017-02-24)
Fodder beet (Beta vulgaris L.) has a very high readily fermentable carbohydrate concentration, which could affect rumen fermentation and reduce enteric methane (CH₄) emissions. The objective of the current study was to ...
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 ...
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 ...
