Effects of a Novel Protease from Bacillus Subtilis K-5 in Low Protein Corn Distiller Dried Grains with Solubles (cDDGS) Based Diets on Performance and Nutrients Digestibility in Broiler Chickens

Effects of exogenous protease on performance, economic evaluation, nutrient digestibility, fecal score, intestinal morphology, blood profile, carcass trait, and meat quality in broilers fed normal diets and diets considered with matrix value

“…However, NC diet lacking nutrients decreased the ATTD of CP and most amino acids, including essential and nonessential amino acids, whereas the supplementation of exogenous protease to NC diet (PA) improved the ATTD of CP and most amino acids. In consistent with the current study, supplementation of exogenous protease to diets increased the apparent AA digestibility of arginine, threonine, isoleucine, aspartate, lysine, serine, and cysteine ( Angel et al, 2011 ; Shad et al., 2022 ). Soybean meal have been known to have substantial antinutritional factors, and thus it caused poor digestibility and growth performance ( Erdaw et al, 2017 ).…”
