Methane Mitigation Potential Assessment of Herbal Lean Meat Product in Deccani Sheep

Methane has global warming potential and also accounts for a significant energy loss to the ruminant animal. The trial was conducted to study the efficacy of dietary supplement herbal formulation AV/LMP/10 (herbal lean meat product) (M/S Ayurvet Limited, India) on methane mitigation potential, digestibility and nutrient utilization in Deccani sheep. 24 growing healthy Deccani sheep (5-6 months) were randomly divided into 2 groups. Control Group T0 was not given any treatment. Group T¬1 supplemented with AV/LMP/10@1kg/tonne of feed for 3 months. Parameters viz. methane emission estimation, body weight, plasma cortisol level, liver marker enzyme estimation, feed analysis, nitrogen balance, and carcass quality traits were studied. The AV/LMP/10 supplemented group T1 emitted significantly (P<0.05) less methane as compared to control group T0. Statistically (P<0.05) AV/LMP/10 supplemented group had significantly superior average daily gain (g) than that of control. DMI, Dry matter digestibility and FCR of AV/LMP/10 supplemented group were significantly (P<0.05) improved. The maximum nitrogen balance was attained in AV/LMP/10 supplemented group T1. Significantly (P<0.05) lower level of cortisol in AV/LMP/10 supplemented animals confirmed the increased resilience of animal towards stress. Animals belonging to AV/LMP/10 supplemented group T1 had significantly higher dressing % as compared to control group T0. The liver marker enzyme levels in both groups were under normal physiological level. Herbal lean meat product AV/LMP/10 was found to be safe for usage and has efficient methane mitigating potential along with added benefit of improvement in digestion, nutrient utility, performance traits in sheep.
