Evaluating Canola (Brassica napus) Meal and Juncea (Brassica juncea) Meal With or Without Supplemental Enzymes for Two Commercial Strains of Laying Hens

Abstract

Two trials compared the effects of canola meal (CM) and juncea meal (JM) with and without dietary enzyme supplementation, on production performance, egg quality, bone quality and liver health characteristics of white- (WSLH) and brown-shell egg laying hens (BSLH). A total of 360 Lohmann LSL-Lite White (Trial 1, WSLH) and 300 Lohmann Brown-Lite (Trial 2, BSLH) laying hens were fed one of 10 isoenergetic and isonitrogenous diets (Soybean meal, 10 % CM, 20 % CM, 10 % JM or 20 % JM with or without a dietary enzyme cocktail of Superzyme OM and Bio-PhytaseTM) for 48 weeks. Based on the results of production performance, incidence of mortality, egg quality, bone quality, and liver health data, up to 20 % CM or JM can be included in diets of WSLH and BSLH without detrimental effects. Enzyme should be included in diets for both WSLH and BSLH.
