	1	Comparative methane estimation from cattle based on total CO_2 production using different techniques显示文摘The objective of this study was to compare the precision of CH4 estimates using calculated CO_2(HP) by the CO_2 method(CO_2 T) and measured CO_2 in the respiration chamber(CO_2 R). The CO_2 R and CO_2 T study was conducted as a 3 × 3 Latin square design where 3 Dexter heifers were allocated to metabolic cages for 3 periods. Each period consisted of 2 weeks of adaptation followed by 1 week of measurement with the CO_2 R and CO_2 T. The average body weight of the heifer was 226 ± 11 kg(means±SD). They were fed a total mixed ration, twice daily, with 1 of 3 supplements: wheat(W), molasses(M), or molasses mixed with sodium bicarbonate(Mbic). The dry mater intake(DMI: kg/day) was significantly greater(P < 0.001)in the metabolic cage compared with that in the respiration chamber. The daily CH4(L/day) emission was strongly correlated(r=0.78) between CO_2 T and CO_2 R. The daily CH4(L/kg DMI) emission by the CO_2 T was in the same magnitude as by the CO_2 R. The measured CO_2(L/day) production in the respiration chamber was not different(P = 0.39) from the calculated CO_2 production using the CO_2 T. This result concludes a reasonable accuracy and precision of CH4 estimation by the CO_2 T compared with the CO_2 R.
