A whole farm BEEF systems Greenhouse gas Emissions Model (BEEFGEM) was developed to determine the effect of varying management practices on greenhouse gas (GHG) emissions from pastoral beef production systems. BEEFGEM simulates two categories of GHG

This experiment sought to establish the response to increasing levels of coconut oil (CO) supplementation with a fixed 0·50:0·50 forage:concentrate diet on intake, digestibility and methane (CH4) emissions. Sixteen continental cross beef heifers (m

An experiment was conducted to establish the effects of feeding refined soy oil (RSO) or whole soybeans (WSB) containing soy oil on DMI, animal performance, and enteric methane (CH 4 ) emissions in young bulls. Thirty-six Charolais and Limousin cross

In some European countries, the majority of annual enteric methane (CH₄) emissions by ruminants occur at pasture - a direct result of the predominance of grazing within ruminant production systems. However, there are only limited data available as

An experiment was conducted to establish the effect of feeding either refined coconut oil (CO) or copra meal containing CO to beef heifers on DMI, animal performance, enteric CH4 emissions, diet digestibility, and the fatty acid profile of the result

The objective of this study was to determine the potential of increased fiber-based concentrates to reduce methane (CH 4 ) production in relation to milk yield from late-lactation dairy cows. The effect of 2 levels of concentrate supplementation (0.8

The microbial fermentability, ruminal degradability and digestibility of 48 maize silages were determined using in vitro gas production (GP), in situ degradability and in vitro digestibility procedures. The silages were produced from forage maize har

Intake, animal performance and methane (CH4) output was investigated using 36 finishing Charolais cross heifers (mean starting weight 462 kg, S.D.±16) fed ad libitum over an 11-week period. Six dietary treatments were investigated in a randomised bl

The objective of this study was to determine the effect of dietary dl-malic acid (MA) supplementation on feed intake, methane (CH(4)) emissions, and performance of mid lactation Holstein-Friesian cows at pasture. Twenty-four (6 primiparous and 18 mul
