Abstract

En 中文

The aim of this experiment was to investigate the efficacy of a bromoform-based (tribromomethane) Investigational Veterinary Product (BB-IVP) on enteric methane production, productivity, carcass traits, and health of cattle when administered via the drinking water of steers fed a total mixed ration. Droughtmaster steers (376 ± 32.4 kg liveweight) were allocated to either a control group (CON; n = 10) offered water without the BB-IVP, or a treatment group (n = 10), where 6.45 mg of stabilised bromoform was included/kg of drinking water in the form of a BB-IVP; this equated to an average of 19 mg bromoform/kg dry matter intake and 0.5 mg bromoform/kg liveweight over the experimental period. Steers consuming the BB-IVP via drinking water had lower feed intake (P < 0.001), with no differences in liveweight gain (P = 0.99), resulting in 15% higher feed conversion efficiency (P = 0.02) compared to the CON steers. Steers consuming the BB-IVP via drinking water had 37.1%, 26.2%, and 36.2% lower methane production (P < 0.001), methane yield (P < 0.001), and methane intensity (P = 0.01), respectively, compared to CON steers. Administering the BB-IVP through drinking water reduced enteric methane production of steers and increased feed conversion efficiency with no detrimental effects on steer health. Water delivery of the BB-IVP may have broader application in extensive ruminant production systems that utilise water reticulation, but further research is required to demonstrate this under different feed-bases, climatic conditions and animal classes to optimise inclusion rates.
