Effect of Terminalia chebula and Allium sativum on in vivo methane emission by sheep.

摘要: Summary A study was conducted to evaluate some plant parts (already tested for their antimethanogenic activity in vitro gas production test the authors’ laboratory) as feed additive combat methane emission from sheep. Sixteen male sheep with average body weight of 29.96 ± 1.69 kg (22 months age) were divided into four groups a randomized block design. The animals fed on diet containing forage concentrate ratio 1:1. fraction composed (in parts) maize grain, 32; wheat bran, 45; deoiled soybean meal, 20; mineral mixture, 2 and common salt, 1. treatments control (without additive), seed pulp Terminalia chebula (Harad), bulb Allium sativum (Garlic) mixture (Mix) latter two equal proportions at rate 1% dry matter (DM) intake. There no effect DM intake due inclusion these additives. digestibilities organic tended be higher (p < 0.1) T. A. sativum, whereas, neutral detergent fibre (NDF), acid (ADF) cellulose (p < 0.05) all three experimental compared control. nitrogen balance plane nutrition not affected by any Methane (L/kg digested intake) estimated open circuit respiration chamber energy loss per cent digestible lower (p = 0.09) Mix (p = 0.08) data indicated that showed activity, whereas both improved nutrient digestibility. Therefore, plants appear suitable candidates use mitigate improve utilization
