Abstract :

This experiment was done for quality improvement and decrease ensiling period from 21 to 14 day. Experimental design was completely randomized design with 5 treatments by adding Lactobacillus plantarum (LP) and Saccharomyses cervicea (Sc). Treatments were, 1) Without any additive such as control (LP0-SC0), 2) 0.5 gr Lactobacillus Plantarum in 100 kg corn forage (LP1-SC0), 3) 0.75 gr L. plantarum in 100 kg corn forage (LP2-SC0), 4) 0.5 gr Saccharomyses Cervicea in 100 kg corn forage (LP0-SC1) and 5) 0.5 gr L. plantarum and 0.5 gr S. cervicea in 100 kg corn forage (LP1-SC1). Silo construction was simulated by dark barrel bung. Sampling and evaluating was done for pH, DM, lactic acid, acetic acid and apparent specifications at the end of 7, 14, 21th days. In each sampling at the end of 14 and 21th days LP2-SC0 had lowest pH and highest lactic acid.. pH and lactic acid at 21 day in LP2-SC0 was significant with other treatment (P<0.05). Therefore by using of suitable microbial additives, can decrease ensiling period from 21 to 14 day and prevent from harmful facts. But corn silage consumption is not recommended less than 21 day.
