An experiment was conducted to investigate the effects of a multicarbohydrase enzyme on egg production parameters, nutrient digestibility, and fatty acid composition in Hy-Line CV-20 laying hens (39 63 wk age) fed diets containing 150 g/kg diet canola seed, flaxseed, or Linpro (flaxseed:peas, 1:1 wt/wt). The effect each parameter also evaluated. Hens consuming seed had greater production, lower feed consumption, therefore better conversion than those flaxseed diets. Enzyme supplementation significantly increased (P < 0.01) (from 78.0 80.9%) improved 0.001) ratio 2.15 2.03) flaxseed. produced eggs with specific gravity from birds 1.0773 1.0800, P phase I experiment. There no fat similar digestibility values were observed for (92.1 vs. 96.7%) (87.4 92.4%). Eggs by greatest n-3 content (562 mg/60 g egg) when compared (207 (427 egg). 546 578 egg; = 415 438 0.05). In addition, addition docosahexaenoic 91.8 101.9 89.4 96.8 diets, respectively. When long-term feeding resulted reduced eggshell quality. positive utilization, quality, deposition egg.
