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.

The yak industry constitutes a pivotal segment of livestock development across the Qinghai–Tibetan Plateau and adjacent pastoral regions. Existing studies have shown that supplemental feeding for grazing yaks significantly improves meat quality growth performance, but its effect on enteric methane (CH4) emission from has never been reported, so present experiment aimed to investigate CH4 emissions in three different periods warm season. Thirty male were randomly assigned two groups, with 15 per group, groups designated as group (GR), traditional methods an initial body weight 94.56 ± 3.9 kg, (GRS) 95.01 4.1 which received 1500 g/d feed 120 days. measured at late regreening period (LRP), greening-grass (GGP), browning (BRP) using SF6 tracer method. results showed GRS increased (p < 0.01) total DMI during season decreased forage intake LRP GGP, resulting reduced yield kg BW gain DMD warm-season 0.01), production energy gross ratio GGP 0.05), similarly decrease BRP 0.01). In conclusion, nutrition alpine grasslands enhances reduces emissions, dietary utilization efficiency.

Methane (CH4) is an anthropogenic greenhouse gas produced by ruminant animals in their conversion of feed to milk or meat. Alga Bio 3.0 (ALB) a proprietary additive containing stabilized, synthetic bromoform which known reduce CH4 emission the rumen cattle. The objective was evaluate effects feeding increasing inclusion algae on DMI, energy and N utilization, total production with headbox-style indirect calorimetry lactating Jersey cows. Twelve mid lactation multiparous cows were utilized quadruplicated 3 × Latin square design consisting periods 28-d each. Treatments randomly assigned so that consumed concentrations (DM basis) ALB: 0% diet DM (0CTRL), 0.46% (0.46LOW) 0.93% (0.93HIGH). Increasing ALB linearly reduced 19.7% L/d 18.4% L/kg DMI (430, 392, 345 ± 22.02 22.8, 20.6, 18.6 1.04 DMI), increased hydrogen (None detected, 15.6, 62.4 22.21 L/d). No differences observed yield, ECM averaging 18.9 0.56 kg, 28.4 0.69 35.1 0.84 respectively. Milk fat percentage decreased (5.22, 5.04, 4.92 0.136%), but no difference yield (average 1.42 0.048 kg/d). DM, neutral detergent fiber organic matter basis (aNDFom), CP, starch, crude digestibility 65.6 0.50%, 43.4 0.99%, 67.1 0.64%, 94.3 0.34%, 73.9 1.88%, concentration metabolizable (ME; 2.49, 2.50, 2.55 0.022 Mcal/kg). efficiency converting digestible (DE) ME (0.88, 0.89, 0.89 0.003 Mcal/Mcal). samples analyzed for presence residues, below limit detection. Results suggest can up 19.6% dairy cows, leading DE ME.
