Methane emissions from Inner Mongolian Cashmere goats at different dietary nutrient levels
Inner Mongolian is a dominating breeding base of Cashmere goats in China.According to the statistics yearbook, the population of total Cashmere goats was 28.087 million and 38％ of the goats are in Inner Mongolia(2005 ),which exist on desert grassland with poor biogeocoenosis, where the Ash, crude fiber and lignin contents of pastures is higher than that of other grassland, so the special breed of Cashmere goat was acclimated.Inner Mongolian Cashmere was named.the best inartificial fiber.and economic value is considerable.So the numbers of Cashmere goats were increasing year by year, but the methane emission of Cashmere goats was still evaluated by models in China and the data of in vivo had not been reported by now.So the objective of this study was to measure methane emission of Cashmere goats on maintenance level and at ad libitum intake using SF6 tracer gas technique,in order to obtain methane emission exactly to provided datum for programming methane emission list and feasible Mitigation Strategies.
