Research on Measuring Greenhouse Gases Emissions of Broilers under the Mode of Net Rearing
摘要
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,N2Oand 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.关键词
