To investigate the greenhouse gases emissions from the feeding and waste management of livestock and poultry, methane and nitrous oxide emissions were estimated from the local measurement and IPCC guidelines during 1990-2000 in Taiwan. Hog is the major livestock and is followed by goat and cattle, while chicken is the major poultry and is followed by duck and geese. Methane emission from enteric fermentation of livestock was 30.9 Gg in 1990, increased to 39.3 Gg in 1996, and then decreased gradually to 34.9 Gg in 2000. Methane emission from the waste management was 48.5 Gg in 1990, reached the peak value of 60.7 Gg in 1996, and then declined to 43.3 Gg in 2000. In the case of poultry, annual methane emission from enteric fermentation and waste management was 30.6-44.1 ton, and 8.7-13.2 Gg, respectively. Nitrous oxide emission from waste management of livestock was 0.78 ton in 1990, increased to 0.86 ton in 1996, and then decreased to 0.65 ton in 2000. Nitrous oxide emission from waste management of poultry was higher than that of livestock with 1.11 ton in 1990, 1.68 ton in 1999, and 1.65 ton in 2000. There is an urgent need to reduce methane emission from enteric fermentation and recover methane from anaerobic waste treatment for energy in livestock and poultry feeding in Taiwan.
为了调查畜禽饲养和废弃物管理产生的温室气体排放，根据1990 - 2000年台湾地区的本地测量数据和政府间气候变化专门委员会（IPCC）指南估算了甲烷和氧化亚氮的排放量。猪是主要的家畜，其次是山羊和牛，而鸡是主要的家禽，其次是鸭和鹅。1990年家畜肠道发酵产生的甲烷排放量为30.9Gg，1996年增至39.3Gg，然后逐渐降至2000年的34.9Gg。废弃物管理产生的甲烷排放量在1990年为48.5Gg，1996年达到峰值60.7Gg，然后降至2000年的43.3Gg。在家禽方面，肠道发酵和废弃物管理产生的甲烷年排放量分别为30.6 - 44.1吨和8.7 - 13.2Gg。1990年家畜废弃物管理产生的氧化亚氮排放量为0.78吨，1996年增至0.86吨，然后降至2000年的0.65吨。家禽废弃物管理产生的氧化亚氮排放量高于家畜，1990年为1.11吨，1999年为1.68吨，2000年为1.65吨。台湾地区迫切需要减少家畜肠道发酵产生的甲烷排放，并从厌氧废弃物处理中回收甲烷用于畜禽饲养的能源。
