Abstract

In this experiment, the feeding values of 5 kinds of whole plant corn silage were evaluated by in vitro gas production and nylon bag methods. Five kinds of whole plant corn silage made from Dafeng 26, Jindan 65, Denghai 679, Luyan 10 and Tunyu 168 silage corn, respectively, were collected to measure the common nutrient component contents. The gas production at different fermentation time was measured by in vitro gas production method, and the gas production parameters were calculated. The dry matter degradation rate was measured by nylon bag method, and the degradation parameters were calculated. The results showed as follows:the acid detergent fiber content of Jindan 65 was the lowest, and the range of crude protein content of 5 kinds of whole plant corn silage was 5.46% to 7.27%. The ether extract content of Jindan 65, Denghai 679, Tunyu 168 was significantly higher than that of Dafeng 26 and Luyan 10 (P<0.05). Jindan 65 had the highest 72 h gas production of 86.70 mL, and the gas production rate of Jindan 65 was significantly higher than that of Denghai 679 and Tunyu 168 (P<0.05). The dry matter degradation rate after 72 h fermentation of Jindan 65 was significantly higher than that of other 4 varieties (P<0.05). In conclusion, whole plant corn silage made of Jindan 65 silage corn has higher nutrient component contents and is easier to be fermented and digested.
