The present study evaluated the chemical composition and in vitro ruminal digestibility of napier Pakchong 1 silage combined with maize cob and husk in different ratios. The napier Pakchong 1 grass was harvested at 45 days of maturity. The napier Pakchong 1 grass was ensiled with maize cob and husk at ratios of 1 : 5, 1 : 10 and 1 : 15. Three rumen fistulated Thai native cattle (White Lamphun cattle) with an average weight of 154 ± 4.7 kg were used to determine ruminal digestibility by in vitro gas-production technique. Gas production was recorded after incubating for 2, 4, 8, 12, 24, 48, 72 and 96 h. The microbial biomass yield was determined after incubating for 24 h. DM, NDF and ADF of maize cob and husk mixed with napier Pakchong 1 silage declined by increasing the proportion of napier Pakchong 1 grass, while gas production after 4–10 h of incubating maize cob and husk mixed with napier Pakchong 1 grass increased by increasing the proportion of napier Pakchong 1 grass. The metabolisable energy, organic matter digestibility and microbial biomass yield did not differ among the different ratios. The results of the study suggested a recommended ratio of maize cob and husk to napier Pakchong 1 grass of 1 : 10. The ensiling fermentation increased the proportion of protein in the roughage, which lead to increased in vitro gas production of roughage.

更正:玉米芯和谷壳与 Napier Pakchong 1 青贮饲料的比例对泰国本土牛瘤胃液的营养价值和体外产气量的影响

本研究评估了 Napier Pakchong 1 青贮饲料与不同比例的玉米芯和玉米壳的化学成分和体外瘤胃消化率。Napier Pakchong 1 草在成熟 45 天时收获。Napier Pakchong 1 草用玉米芯和玉米壳按 1:5、1:10 和 1:15 的比例青贮。三头平均重量为 154 ± 4.7 kg 的瘤胃瘘泰国本地牛(白南奔牛)用于通过体外产气技术测定瘤胃消化率。在孵育 2、4、8、12、24、48、72 和 96 小时后记录气体产量。培养24小时后测定微生物生物量产量。玉米芯和谷壳与napier Pakchong 1青贮混合的DM、NDF和ADF随着napier Pakchong 1草比例的增加而下降,而将玉米芯和谷壳与 Napier Pakchong 1 草混合培养 4-10 小时后产气量会随着 Napier Pakchong 1 草比例的增加而增加。不同比例的代谢能、有机物消化率和微生物生物质产量无差异。研究结果表明,玉米芯和谷壳与napier Pakchong 1 草的推荐比例为1:10。青贮发酵增加了粗饲料中蛋白质的比例,从而增加了粗饲料的体外产气量。
