Abstract :The focus of this research was to investigate the effects of hazelnut husk on the low dry matter maize silage quality, microbial profile, deterioration, fiber components, and digestion parameters. Second crop maize was harvested at the milk stage of maturity insert ignore into journalissuearticles values(26.61% DM); and ensiled in laboratory silos with or without ground hazelnut husk. A total of 18 jars of silage were made utilizing two treatments insert ignore into journalissuearticles values(control silage and 15% hazelnut-contained silage);, three different opening dates, and three replicates. All silage analyses were completed during all of the opening periods. Hazelnut husk increased insert ignore into journalissuearticles values(P<0.05); silage DM, pH, ash, protein, and cellulose fractions content while decreasing insert ignore into journalissuearticles values(P<0.05); only hemicellulose. The lactic acid, propionic acid, acetic acid, and butyric acid in silages were reduced insert ignore into journalissuearticles values(P<0.05); by hazelnut husk. The addition of hazelnut husk to the silages increased insert ignore into journalissuearticles values(P<0.05); the population of lactobacilli but had no influence insert ignore into journalissuearticles values(P>0.05); on the yeast-mold population. Hazelnut husk increased insert ignore into journalissuearticles values(P<0.05); aerobic stability in maize silages. Hazelnut husks reduced in vitro gas production value, digestible organic matter, metabolic energy, and net energy lactation values, but increased protozoa in the rumen insert ignore into journalissuearticles values(P<0.05);. Hazelnut husk demonstrated a potential hygroscopic property in low dry matter maize silage by increasing silage DM and improving fermentation efficiency, as well as air stability during feedout.
