摘要: Objective: This study was aimed at evaluating effects of cattle breed resources and alternative mixed-feeding practices on meat productivity emission intensities from household farming systems (HFS) in Daklak Province, Vietnam. Methods: Records Local Yellow×Red Sindhi (Bos indicus; Lai Sind) 1/2 Limousin, Drought Master, Red Angus during the growth (0 to 21 months) fattening (22 25 periods were used better understand variations enteric methane emissions. Parameters determined by ruminant model. Four scenarios developed: (HFS1) grazing birth slaughter native grasses for approximately 10 h plus 1.5 kg dry matter/d (0.8% live weight [LW]) a mixture Guinea grass (19%), cassava (43%) powder, cotton (23%) seed, rice (15%) straw; (HFS2) period fed with elephant (1% LW) supplementation (1.5% bran (36%), maize (33%), (31%) meals; HFS3 HFS4 computed grass, but concentrate reaching 2% 1% LW, respectively. Results: Results show that compared HFS1, emissions (72.3±0.96 CH 4 /animal/life; least squares means± standard error mean) 15%, 6%, 23% lower (p < 0.01) HFS2, HFS3, HFS4, The predicted efficiencies (CO 2 eq) per LW (4.3±0.15), carcass (8.8±0.25 kg) edible protein (44.1±1.29) also 0.05) HFS4. In particular, irrespective HSF, feed supply ratio changes had more positive impact when crossbred than their counterparts. Conclusion: Modest improvements feeding integrated modelling frameworks may offer potential trade-offs respond climate change
