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.
