Biochar from pyrolyzed Tibetan Yak dung as a novel additive in ensiling sweet sorghum: An alternate to the hazardous use of Yak dung as a fuel in the home

Yak dung is used as fuel in Tibetan homes; however, this use hazardous to health. An alternative of the that would be profitable and offset loss a very beneficial. Sweet sorghum silage with yak biochar an additive was compared control no additives three silages different commercial additives, namely Lactobacillus buchneri, plantarum Acremonium cellulase. Biochar-treated had significantly greater concentration water-soluble carbohydrates than other (76 vs 12.4–45.8 g/kg DM) crude protein content (75.5 61.4 DM), lactic acid (40.7 27.7 gross energy yield (17.8 17.4 MJ/kg) silage. did not differ vitro digestibility total gas (507 511 L/kg methane production (57.9 57.1 DM). Biochar inhibited degradation enhanced production, which improved storability feed. It concluded efficient, cost-effective ensiling additive. The profit could improve health people.
