Disclosed is an animal feed composition suitable for oral administration to an animal comprising an immune stress-reducing enzyme in an effective amount to decrease the level of positive acute phase protein in said animal, increase the level of negative acute phase protein in said animal, and/or improve animal growth performance in an orally acceptable carrier, wherein: i. said effective amount is at least 20 IU enzyme/kg feed; ii. said enzyme is other than a beta-mannanase-type hemicellulase or phospholipase; and iii. said enzyme is selected from the group consisting of 1,3-beta-glucanase, beta-glucosidase, xyloglucanase, RNAse L, dsRNA specific adenosine deaminase, CG specific restriction endonucleases, N-glycanases, alpha-1,2-fucosidase, alpha-1,3-1,4-fucosidase, alpha-1,6-mannosidase, alpha-1,2-mannosidase, alpha-1,3-mannosidase, beta-1,4-galactosidase, endo-beta-N-acetylglucosaminidase F (endo F), peptide-N-(N-acetyl-beta-glucosaminyl)asparagine amidase F (PNGase F), PNGase A, endo-beta-N-acetylglucosaminidase H (endoH), endo D, endo C, alpha-N-acetylgalactosaminidase, beta-1,3-galactosidase, endo-N-acyl-neuraminidase (endo N), a-2,3-neuraminidase, a-2,6-neurminidase, alpha-2,8-neuraminidase, beta-N-acetylhexosaminidase, endo-beta-N-galactosidase, endo-alpha-N-acetylglactosaminidase, endo-alpha-1,6-D-mannanase, arabinogalactanase, alpha-mannanase, alpha-mannosidase, sphingomyelinase, chitinase, chitin deacetylase, carbohydrate deacetylase, N-acetylglucosaminidase, phosphatidylserine decarboxylase, sulfatase, beta-galactosidase, arabinanase, hyaluronidase, alpha-arabinofuranosidase, chondroitinase, glucocerebrosidase, methyl esterase, ferulic acid esterase, furuloyl esterase, acetyl esterase, phosphorylcholine hydrolase, alkaline phosphatase, acid phosphatase, phosphorylcholine esterase and phosphorylcholine phosphatase. |
