Abstract

The study aims to investigate the effects of mixing ratio of alfalfa and sweet sorghum on nutritional quality and aerobic stability of total mixed ration (TMR) silage, and then to determine the appropriate mixing ratio of those two forages. The mixing ratio of alfalfa and sweet sorghum were 10:0, 7:3, 5:5, 3:7 and 0:10, which were recorded as T1, T2, T3, T4 and T5 groups, respectively, and then mixed with concentrate at 6:4 to formulate 6 TMR. After 60 days of silage, the nutritional component contents, fermentation quality and the dynamic changes of main microorganisms after 0 (the moment of opening), 3, 6, 9 and 12 days of aerobic exposure were measured. The results showed as follows:1) the dry matter content in TMR silage gradually decreased with the increasing of the proportion of sweet sorghum, while the crude protein content increased relatively. The crude protein content in T2 group was the highest (19.59%), which was significantly higher than that in other groups (P<0.05) except T3 group. The ether extract content in T5 group was the lowest (2.12%). There was no significant difference in neutral detergent fiber content among groups (P>0.05). 2) With the increasing of the proportion of sweet sorghum, the content of lactic acid increased gradually. The pH of TMR silage in each group was lower than 4.2, the ammonia nitrogen/total nitrogen was less than 10%, and a small amount of propionic acid was detected, while no butyric acid was detected. 3) After aerobic exposure, the amount of lactic acid bacteria of TMR silage in each group decreased gradually with the prolongation of aerobic exposure time, while the amounts of aerobic bacteria and yeasts increased gradually. 4) The energy values of TMR silage decreased gradually with the increasing of the proportion of sweet sorghum, and the energy provided by TMR silage in T1 and T2 groups were higher than other groups. Considering the nutritional component contents, fermentation quality, aerobic stability and energy provided by TMR silage, it is recommended that the mixing ratio of alfalfa and sweet sorghum in TMR silage is 7:3, which TMR silage can be used in beef production of Guizhou area.
