摘要:

本试验旨在利用呼吸舱测定白羽肉鸡温室气体(CO2、N2O和CH4)的排放量并研究其排放趋势。选取300只体重相近、健康的1日龄爱拔益加肉鸡,平均分配在3个呼吸舱中,网上平养至42日龄。试验期间实时监测通风量及进气口、排气口处的CO2、N2O和CH4浓度,计算气体排放量。结果表明,白羽肉鸡平均CO2、N2O和CH4排放量分别为(31.40±11.45) g•d-1•bird-1、(9.13±0.43) mg•d-1•bird-1和(0.40±0.15) mg•d-1•bird-1;42 d生长期内CO2、N2O和CH4总排放量分别为(1 318.94±480.91) g•bird-1、(374.01±17.68) mg•bird-1和(16.67±6.17) mg•bird-1。肉鸡CO2和N2O每日排放量均随日龄增加而增多,且分别在24和27日龄之后维持在平稳状态;CH4排放较少,在评估温室气体对环境的影响时可以不予考虑。

Abstract:

The present study was conducted to measure greenhouse gases (CO2, N2O and CH4) emissions and investigate emission characteristics of broilers using respiratory chambers. Three hundred Arbor Acres broilers (1-day-old) with good health and similar weight were randomly allotted into 3 respiratory chambers, and reared on the net until 42-day-old. A continual monitoring system for ventilation rate and the greenhouse gases concentration were used in this research to determine the 3 gases(CO2, N2O and CH4) emissions. The results showed as follows: the CO2, N2O and CH4 emissions for broilers were (31.40±11.45) g•d-1•bird-1, (9.13±0.43) mg•d-1•bird-1 and (0.40±0.15) mg•d-1•bird-1, respectively. Total CO2, N2O and CH4 emissions from 1-day-old to 42-day-old were estimated: (1 318.94±480.91) g•bird-1, (374.01±17.68) mg•bird-1 and (16.67±6.17) mg•bird-1, respectively. The daily emissions of CO2 and N2O increased with the growth of age of broilers, and then remained stable after 24-day-old and 27-day-old, respectively. The CH4 emissions were relatively lower, and could be ignored when assessing the effect of greenhouse gases on environment.
