Özet

The effects of homofermentative and heterofermentative lactic acid bacteria (LAB) on fermentation characteristics of maize silage and lamb performance were investigated. Maize, harvested at milk line stage of maturity, treated with homofermentative LAB or L. buchneri, a heterofermentative LAB, at 1.0x10(4), 1.0x10(5) and 1.0x10(6) colony forming units/g (cfu/g) of herbage and ensiled in mini silos for 42 days. Only the highest level of homofermentative LAB produced silage with a more homolactic fermentation profile, whereas application of L. buchneri at 1.0x10(5) cfu/g produced silage with a more heterolactic fermentation profile. This effect was more pronounced with increasing rate of L. buchneri. However, silage treated with the highest level of L. buchneri tended (P=0.06) to have lower dry matter recovery. Baled maize silages were treated with homofermentative LAB or L. buchneri at 1.0x10(6) cfu/g before ensiling. Homofermentative LAB had no (P > 0.05) effect on preservation characteristics of baled maize silages. However, application of L. buchneri increased the concentration of acetic acid (P < 0.05) and aerobic stability (P < 0.01) of baled maize silage. There was no (P > 0.05) treatment effect on any variables measured on lamb performance. It can be concluded that treating maize with L. buchneri increases the aerobic stability of baled maize silage through the accumulation of acetic acid and elevated acetic acid in well fermented silages does not depress the dry matter intake.
