title: Nutritive value of cold-pressed camelina cake with or without supplementation of multi-enzyme in broiler chickens.
abstract: The objectives were to determine the standardized ileal digestibility (SID) of amino acids (AA) and AMEn value of cold-pressed camelina cake (CPCC) and the effect of adding multi-enzyme to a corn-CPCC diet for broilers. The 600 male broiler chicks were divided into 40 groups and fed 5 diets in a completely randomized design (8 groups per diet) from d 15 to d 21 of age. A corn basal diet and the basal diet with 30% of it replaced by CPCC were used in a 2 × 2 factorial arrangement with or without multi-enzyme (2,800 U of cellulase, 1,800 U of pectinase, 400 U of mannanase, 50 U of galactanase, 1,000 U of xylanase, 600 U of glucanase, 2,500 U of amylase, and 200 U of protease/kilogram of diet; Superzyme OM, 1 g/kg). The fifth diet was N-free. The corn basal diet was fed to determine nutrient digestibility and retention for CPCC by substitution. The N-free diet was fed to estimate basal endogenous AA losses for determining SID of AA. Diets contained TiO2 as indigestible marker. On a DM basis, CPCC contained 39.8% CP, 38.3% neutral detergent fiber, 12.7% ether extract, 1.89% Lys, 0.70% Met, 1.56% Thr, and 0.45% Trp. The SID of Lys, Met, Thr, and Trp for CPCC were 76.5, 85.5, 72.8, and 84.1%, respectively. The AMEn value for CPCC was 1,671 kcal/kg of DM. Multi-enzyme supplementation increased (P < 0.05) the SID of Met and Thr and the AMEn value of the corn-CPCC-based diet by 1.4, 1.3, and 3.0%, respectively. The multi-enzyme increased (P = 0.026) the AMEn value of CPCC from 1,671 to 1,941 kcal/kg of DM. In conclusion, the CPCC evaluated in the present study can be included in poultry diets as a source of energy and AA. Multi-enzyme supplementation increased the AMEn value of CPCC for broilers.
