An in vivo experiment was performed to determine the effect of level of maize starch in the diet on digestion and site of digestion of organic matter, starch and neutral detergent fibre (NDF). In a repeated change-over design experiment, three cows fitted with a rumen cannula and T-piece cannulae in
A dynamic, mechanistic model of enteric fermentation was used to investigate the effect of type and quality of grass forage, dry matter intake (DMI) and proportion of concentrates in dietary dry matter (DM) on variation in methane (CH4) emission from enteric fermentation in dairy cows. The model rep
To study the persistency of the effect of supplementing a whey protein emulsion gel (WPEG) of a mixture of linseed and soybean oil on milk fatty acids, a 10-wk experiment was carried out with 32 lactating Holstein Friesian dairy cows. During the first 5wk, all cows were managed on a restricted grazi
