Effects of oil and natural or synthetic vitamin E on ruminal and milk fatty acid profiles in cows receiving a high-starch diet [PDF]

open access: yes, 2012
Among trans fatty acids, trans-10,cis-12 CLA has negative effects on cow milk fat production and can affect human health. In high-yielding dairy cows, a shift from the trans-11 to the trans-10 pathway of biohydrogenation (BH) can occur in the rumen of ...

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs

open access: yesAgribusiness, EarlyView.
ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

METHANE PRODUCTION IN DAIRY COWS

open access: yesJournal of Dairy Science, 1979
Abstract The relationship among diet composition, intake, and methane production was investigated with data during 404 total energy balance trials with Holstein cows. Methane production in all trial was measure in open circuit respiration chambers. The most useful predictor of total methane productin was amounts of soluble residue, hemicellulose, and
