Study on Microbiological Fermented Feed Made of Hongyingzi Sorghum Straw
The sorghum straw was chopped(2~3 cm),kneaded,and added bacteria and Maotai flavor distiller's grains,and then fermented anaerobically for 7 months.Afterwards,the contents of moisture,crude protein,crude fat,calcium,total phosphorus,neutral detergent fiber,acid detergent fiber and lig-nin were determined to analyze the impact of different microbiological silage treatments on the nutrition values of the feed.The results showed there was no significant difference in feed moisture content among each group.However,significant differences were observed in crude protein,crude ash,crude fat,neutral detergent fiber,acid detergent fiber,lignin,calcium,total phosphorus and calcium phosphorus ratio in feed(P<0.01).The palatability from high to low was group 10>Group 11>Group 9>Group 12>Group 7>Group 6,With groups 1 to 5 having similar palatability.Compared with the chopped sorghum straw,the crude protein,crude fat,lignin and calcium phosphorus ratio of the treatment group significantly changed by kneading,adding microbial inoculants and distillers'grains,among them,"chopping+knea-ding+inoculant+20%~30%distiller's grains"has best effect as cattle feed.
