Effects of exogenous amylolytic enzymes on fermentation, nutritive value, and in vivo digestibility of rehydrated corn silage

Amylolytic Enzyme in Rehydrated Corn and Sorghum Grain Silage in the Diet of Ears

“…With the exception of RCGS, all silages had acceptable pH values (3.6 to 4.2) (Oliveira et al, 2019). This nding may be related to the greater amount of ammonia that neutralized the desirable acids resulting in a nal pH increasing even with a greater amount of LAB (SILVA et al, 2020), corroborating the high presence of fungi, total and aerobic bacteria.…”

“…RCGS was the treatment with the lowest fraction "a" (37.61%), this is due to the greater microbial activity observed, which consumed highly fermentable carbohydrates, reducing the amount of carbohydrates in the "a" fraction (Oliveira et al, 2019).…”

“…Losses of DM during the fermentation process result in increased concentrations of more than 11% NDF, due to the effect of concentration, as it is an insoluble fraction, which is not used by microorganisms as a substrate during the period that the material was ensiled (Oliveira et al, 2019).…”

“…The treatments containing α-AMYLASE had a higher soluble fraction, and RSGS+E had a higher fraction "a" (54.09), due to the effect of α-AMYLASE that hydrolyzed starch into smaller molecules, intensifying the amount of fermentable carbohydrates, facilitating the action of bacteria in the rumen environment (Oliveira et al, 2019), however, was the treatment that presented the highest fraction C (0.09%) and FI (23.9%).…”

“…The reconstitution and silage process of the grain makes starch more available to be used in the rumen fermentation process (Ferraretto et al, 2015). The addition of exogenous enzymes in the silage of rehydrated grains helps the starch digestive process (Oliveira et al, 2019).…”
