Corn stover was taken after harvesting the ears immediately, chopped using a harvester chopper machine to 1.5-2.0 cm of length, and supplemented with energy additive (corn grains and molasses), protein additive (soybean, urea, and optegin) and microbial inoculants (effective microorganisms EM1) and their interactions and ensiled in plastic bags for 45 days. After the ensiling period, representative samples were taken for determination of chemical composition and silage quality traits. Adding ground corn grains to corn stover silage led to a significant (P<0.05) increase in DM content. Moreover, NFE content of corn stover silage increased significantly (P<0.05), however, ash content decreased significantly (P<0.05) with molasses and ground corn grains supplementation. Soybean meal supplementation increased significantly (P<0.05) DM content than those of urea and optigen supplementationwith insignificant differences with control. The crude protein content of corn stover silage increased significantly (P<0.05) with soybean meal, urea, and optigen supplementation. Ash content decreased significantly (P<0.05) with soybean meal supplementation. Effective microbes supplementation led to a significant (P<0.05) increase in the contents of CP and NFE of corn stover silage and a significant (P<0.05) decrease in the contents of CF and ash. The interaction between energy and protein supplementation showed a significant difference (P<0.05) in DM content only. Interactions among energy, protein, and effective microbes supplementation showed a significant differences (P<0.05) in DM content only. The pH value of the silage decreased significantly (P<0.05), however lactic acid concentration increased significantly (P<0.05) with molasses and ground corn grains supplementation. The pH value of silage was higher significantly (P<0.05) with urea and optigen compared to control and soybean supplementation. Urea-supplemented silage recorded significantly (P<0.05) the NH3-N concentration followed by optigen, then soybean meal, whoever control had the lowest concentration. Moreover, soybean mealsupplemented silage showed significantly (P<0.05) higher concentrations of TVFA’s and lactic acid compared to urea-supplemented silage. The concentrations of NH3-N and lactic acid increased significantly (P<0.05) with effective microbes supplement to corn stover silage. Energy and protein supplementation interaction revealed that urea with molasses or ground corn grains recorded significantly (P<0.05) higher pH values and NH3-H concentration of silage compared to soybean with molasses or ground corn grains. However, soybean meal with molasses or ground corn grains recorded significantly (P<0.05) higher concentrations of TVFA’s and lactic acid in silage compared to urea with molasses or ground corn grains. The interaction between protein and effective microbes showed that urea with EM1 supplemented silage had significantly (P<0.05) higher pH value and NH3-N concentration and lower TVFA’s and lactic acid concentrations than those of soybean meal with EM1. The interaction among energy, protein, and effective microbes showed that molasses or ground corn grains with urea plus EM1 supplemented silages had significantly (P<0.05) higher pH value and NH3-N concentration and lower TVFA’s and lactic acid concentrations than those of molasses or ground corn grains with soybean meal plus EM1.

The effect of inoculation on nutrient content, fermentation, aerobic stability, and beef cattle performance for whole-plant corn silage treated with a commercial product (blend of homo- and heterofermentative lactic acid bacteria, BSM, blend of Enterococcus faecium, Lactobacillus plantarum, and Lactobacillus brevis, DSM numbers 3530, 19457, and 23231, resp.), was compared to a control treatment with no silage additives (CT). The material had a DM of 323 g/kg, crude protein, and water-soluble carbohydrate concentrations of 87.9 and 110.5 g/kg DM, respectively. BSM increased the fermentation rate with a significantly deeper pH (P < 0.01), a significant increase in the total organic acids concentration (P < 0.05), more lactic acid (P < 0.01), and numerically more acetic acid compared to CT. BSM significantly decreased the concentrations of butyric acid (P < 0.01), ethanol, and ammonia-N compared to the CT. BSM-treated silage decreased DM by 3.0 % (P < 0.01) and had a hig...

Potato hash was mixed with wheat bran at 7:3 ratio, treated with homofermentative LAB inoculant (BMF, bonsilage forte), heterofermentative lactic acid bacteria (LAB) (LFLB, Lalsil Fresh LB) and without LAB inoculant and ensiled in 210 L drums for 90 days. After 90 days of ensiling, concentrates that contained 40% potato hash silage (PHS) were formulated and the treatment groups were control (no silage), untreated PHS, BMF treated PHS and LFLB treated PHS. The diets were fed to 64 growing pigs (60 days old and 30.4 ± 2.3 kg body mass). The pigs were allocated in a complete randomized block design with four treatments, and each treatment consisted of eight boars and eight sows. Pigs were fed ad libitum, feed intake was measured daily while body masses were recorded at the start and weekly throughout the experimental period. The dry matter intake (DMI) was higher in the control diet (1062 g/kg) than in the untreated PHS diets (933 g/kg), BMF treated PHS (873 g/kg) and LFLB treated PHS ...

An in vitro study was planned to assess the effects of a homofermentative microbial inoculant on the fermentation parameters and nutritive value of corn silage. The inoculant was applied at concentrations of 5x104cfu/g of forage (T1), 1x105cfu/g of forage (T2) 1.5x105cfu/g of forage (T3) and a negative control group (T0) without bacterial inoculant in three replicates each. At day 3, 7, 45 and 90 of the experiment individual buckets were opened to characterize the material, quick acidification, dry matter recovery, and aerobic stability of silage respectively. The temperature of the trial samples was 32.75±1.92 throughout the trial duration. A rapid and significant reduction in pH even at third day of trial from 6.5 to 3.61 in the treatment (T2 and T3) groups and remained consistent till 90 day of experiment (with non-significant fluctuations) when compared with control group (6.5 to 5.0). The levels of lactic acid, acetic acid and propionic acids were significantly (P<0.05) high...
