ABSTRACT: Dietary carbohydrate manipulation can be used to reduce enteric CH4 emission, but few studies have focused on the interaction of the different types of carbohydrates that can affect feed intake and ruminal fermentation. Understanding this i

ABSTRACT: Enteric CH4 produced from dairy cows contributes to the emission of greenhouse gases from anthropogenic sources. Recent studies have shown that the selection of lower CH4-emitting cows is possible, but doing so would be simpler if performan

ABSTRACT: Fat in the form of cracked rapeseed and 3-nitrooxypropanol (3-NOP, market as Bovaer) were fed alone or in combination to 4 Danish Holstein multicannulated dairy cows, with the objective to investigate effects on gas exchange, dry matter int

Abstract Enteric methane (CH4) emission is one of the major greenhouse gasses originating from cattle. Iodoform has in studies been found to be a potent mitigator of rumen CH4 formation in vitro. This study aimed to quantify potential of iodoform as

Current perovskite oxide electrolytes, i.e., acceptor-doped Ba(Ce,Zr)O3-δ, exhibit proton conductivity ranging from 10−3 to 10−2 S cm−1 at 600 °C for protonic ceramic fuel cells (PCFCs), which rely on the structural defects. However, bulk dop
