Abstract The livestock sector plays a crucial role in mitigating global climate change by reducing greenhouse gas emissions, with enteric fermentation as the largest source. Although various approaches have been proposed to decrease methane (CH4) feed additives containing bromoform (CHBr3) shown promise minimal impact on animal production parameters. This study aimed evaluate effects of two Rumin8 Investigational Veterinary Products (IVP) synthetic CHBr3 parameters, and rumen environment. Twenty-four Angus beef steers were randomly assigned one three treatment groups: Control, Oil (8 mL oil IVP/kg DMI), Powder (1.2 g powder DMI). IVP resulted intake 32.2 mg/kg DMI, while provided 2.0 DMI during weeks 1–8. In week 9, new batch increased 17.9 DMI. group exhibited 95.0%, 96.1% reductions CH4 (g/day), yield (g/kg intensity average daily gain), respectively, accompanied 925%, 934%, 858% increases H2 production, yield, intensity, respectively. Neither significantly affected parameters or environment variables. These findings suggest that has potential reduce emissions. warrants further investigation, this is first published vivo assess compound efficacy.
