青贮玉米与全株大豆混合比例对青贮品质的影响
Effects of Different Mixing Ratios on the Quality of Corn-soybean Whole Plant Mixed Silage
摘要
Abstract
In order to explore the effect of different mixing ratios on the silage of whole corn and soybean,the 7 treatments were set to ensiled:Silage corn(CK1),whole soybean(CK2),silage corn with soybean 1∶1(M1),silage corn with soybean 2∶1(M2),silage corn with soybean 3∶1(M3),silage corn with soybean 4∶1(M4),and silage corn with soybean 1∶2(M5).After 90 days of silage,the sensory evaluation,fermentation quality,nutritional value and aerobic stability were determined.The results showed that the sensory evaluation of CK1 and CK2 were rated as'good',and the rest were rated as'excellent'.CK2 had the highest pH(4.69)and the pH of the rest treatments was below 4.2.The lactic acid content in M1,M2 and M3 was significantly higher than that in other treatments.The acetic acid in CK2 was significantly higher than that in other treatments(P<0.05).The content of crude protein increased with the increase of the proportion of whole soybean,and the content of starch increased with the increase of the proportion of silage corn.The content of medium detergent fiber and acid detergent fiber in mixed treatments were significantly lower than that in CK1 and CK2.The RFV from high to low was M1>M2>M3>M4>M5>CK2>CK1.The aerobic stability of mixed silage was better than CK1 and CK2.It can be seen that the fermentation quality,nutritional value and aerobic stability can be improved by mixing corn and bean,and the best mixing ratio of corn and bean was 1∶1.关键词
