Two experiments were conducted to study effects of dietary nitrate on enteric methane production, blood methemoglobin concentration, and growth rate in cattle. In Exp. 1, 36 Holstein steers (288 ± 25 kg BW) were fed increasing levels of dietary nitr

The availability and efficient use of the feed resources in Asia are the primary drivers of performance to maximise productivity from animals. Feed security is fundamental to the management, extent of use, conservation and intensification for product

The present study was designed to investigate the efficacy of control of lactic acidosis by immunisation against lactic acid-producing bacteria, Streptococcus bovis and Lactobacillus. Ten steers were allocated to two treatment groups. One group was i

Three experiments were conducted to investigate interactions between acetate and glucose metabolism in sheep fed on roughage-based diets, and to establish whether the clearance rate of an intravenous acetate load would provide a valid index of the di

A procedure is described for solving an open, fully exchanging, three-compartment model representing ruminal volatile fatty acids (VFA) kinetics in sheep. This model was solved using results from a published study in which labelled VFA, viz. 1-14C-ac

Rates of methane (CH4) production and the sources of carbon (C) for its synthesis were studied in four mature ewes when dosed with a CH4-mitigating ionophore ICI-111075, or monensin, or when untreated. The sheep were given 700 g/day of chaffed lucern

Minimising enteric CH4 emissions from ruminants is a current research priority because CH4 contributes to global warming. The most effective mitigation strategy is to adjust the animal’s diet to complement locally available feed resources so that o

Streptococcus bovis is an important lactic acid bacterium in the rumen, which contributes to the development of lactic acidosis. This study was designed to test the efficacy of immunization with S. bovis primed either intramuscularly (i.m.) or intrap

Lactic acidosis is a gastrointestinal disorder resulting from the rapid overgrowth of lactic acid-producing bacteria when ruminants are suddenly introduced to grain feed. The present study has investigated the ability of live and killed bacterial vac

The effects of dietary nitrate (NO3) and elemental sulfur (S) on nutrient utilisation, productivity, and methane emission of Merino lambs were investigated. Forty-four lambs were randomly allocated to four groups (n = 11) fed isonitrogenous and isoen
