Effects of Different Additives on Silage Quality of Marigold Stem and Leaf

PurposeTo solve the problem of separate ensilage of marigold stems and leaves.

MethodMarigold stems and leaves after picked the commercial flowers were used for mixed ensilage. 10% maize powder, bran, whole corn and straw were added into the stems and leaves of marigold, respectively. The sensory quality, lignocellulose constituents, nutrition and fermentation quality of the stem and leaf of marigold were evaluated after 50 days ensilage.

ResultsAll mixed silage could improve the sensory quality of marigold stem and leaf, and the best sensory quality was the mixed by marigold stem and leaf and maize powder. The contents of neutral detergent fiber, acid detergent fiber, lignin and crude fiber were significantly reduced (P<0.05) in maize powder mixed with marigold stem and leaf silage, but the relative feeding value was also the highest. While the fermentation quality of marigold stem and leaf mixed with whole corn was the best in pH value, organic acid content, and ammonia nitrogen/total nitrogen.

ConclusionThe mixed silage of maize powder and marigold stem and leaf is recommended for practical production.
