摘要: 本研究旨在分析不同紧实度对全株玉米(Zea mays)青贮品质变化的影响,以便筛选出适宜的青贮紧实度。以新饲玉10号青贮玉米为材料,青贮装料密度设计为5个(350、400、500、600、700 kg·m-3),分别在青贮制作完成后1、3、5、7、9、15、30、50 d取样,测定青贮料的干物质(DM)、粗蛋白(CP)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、水溶性碳水化合物(WSC)和pH,并动态监测开窖后各处理青贮内部温度变化规律,同时对比开窖前后的相对饲喂价值(RFV)。结果表明,青贮时间和紧实度的交互作用仅对CP、ADF和pH有极显著影响(P<0.01),对DM、NDF和WSC均无显著影响(P>0.05)。处理600 kg·m-3的pH最低且CP含量最高;处理700 kg·m-3的DM、WSC以及RFV值含量最高,NDF及ADF含量最低。处理600 kg·m-3有氧暴露后稳定的时间显著高于其它处理(P<0.05),达到100 h。同时,有氧暴露时间与温度呈现出单调递增的趋势,且相关性显著(P<0.05)。随着紧实度的增大(350~600 kg·m-3),青贮饲料的品质增加,有氧稳定性提高;当紧实度为600 kg·m-3时,品质较700 kg·m-3变化不显著,600 kg·m-3为最佳紧实度,建议采用。

Abstract: In this study, the whole plant corn (Zea mays) silage nutritional quality at different compactions was analyzed to determine the appropriate compaction of silage. The treatments used Xinsiyu 10 for silage materials with five compaction degrees (350, 400, 500, 600 and 700 kg·m-3). Sampling and determination of the DM, CP, NDF, ADF, WSC and RFV of silages were done on the 1 st, 3rd, 5th, 7th, 9th, 15th, 30th and 50th day after ensiling. Dynamic monitoring of the temperature change of each silage treatment was also measured after opening silo. Results indicated that DM, CP, NDF, ADF, and WSC content and pH value from compaction degree of corn silage decreased significantly than before ensiling (P<0.05). Silage time had a significant effect on above indicators (P<0.01). After opening silo, 600 kg·m-3 had the lowest pH value, while the content of CP was the highest; DM, WSC and RFV of 700 kg·m-3 treatment was the highest, NDF and ADF was the lowest. The stable time after exposure to oxygen of treatment 600 kg·m-3 was significantly higher than other treatments (P<0.05), reaching 100 h. At the same time, there was a monotonic increasing trend of oxygen exposure time and temperature, and the correlation was significant (P<0.05). With the increasing of charge degree range (350~600 kg·m-3), the fermentation quality of the silage correspondingly increased. When compaction degree reaching to 600 kg·m-3, the quality did not change significantly, suggesting that 600 kg·m-3 is the best compaction.
