摘要

China has been extending the ammoniated straw and silage technology all over the country to improve the cattle productivity since 1978. By 1998, treated straw as feed had grown to about 154.98 million tons. This paper analyzed the effect of treated straw on methane emissions from yellow cattle based on treated crop residues. Field experiments show that silage and ammonia treatment technology could increase the straw digestibility 10% to 20%. The estimation based on IPCC good practice showed that methane emission factors were lower 26 % and 30% for the mature female and adult steers of yellow cattle eating ammoniated or silage treated versus non-treated residues due to the increased digestibility. It is estimated that extension of treated straw project may result in 1253.5 Gg/year or 21% of CH_4 emission reduction from yellow cattle in 1998. Further field experiments on CH_4 emission of yellow cattle are needed to approve this analysis results.
