Effect of feeding tanniferous diets on methane emissions in sheep

The present study was designed with the objective of in vitro and in vivo evaluation of methane emissions with tanniferaous feeds in Deccani ram lambs. In vitro studies were conducted to select one tanniferous diet based on in vitro dry matter digestibilities (IVDMD) and mean methane emissions for inclusion in vivo studies. During second phase in vivo studies, 12 Deccani ram lambs of uniform body weight (16.5±0.64 kg with130.11±3.00 days of age) were randomly allotted to 2 treatments in a completely randomized design. Metabolic studies conducted for nutrient digestibility studies and Respiratory chamber was used for estimation of methane emissions In in vitro studies observed that 3.6 per cent increase in vitro dry matter digestibilities and 3.2 per cent reduction in methane emissions with T1 (Horse gram) tannins over group average. In in vivo studies, the nutrient digestibilities increased (P
