Effect of Hybrid Type on Fermentation and Nutritional Parameters of Whole Plant Corn Silage

摘要

Two corn hybrid types, dual-purpose and silage-specific, were harvested at the one half to three fourths milk line and ensiled in fermentation bags for 60 days. Parameters such as fermentation quality, chemical composition, yield prediction and energy value, carbohydrate profile, and in situ digestibility were evaluated for the comparison of two corn types. Our analysis for the above parameters showed that under favourable production conditions, for whole-plant corn silage, the nutritive value per unit was higher for dual-purpose corn, but biomass yield and nutritive value per ha were higher in silage-specific corn. Our current study provides data for whole-plant corn silage research and reference data for ruminant nutrition in selecting corn silage.
