observed that broiler diets containing high amounts of white lupin kernels (50–70%) depressed productive performance severely but dietary supplementation with different enzymes improved performance significantly. An important purpose of the present experiment was to examine if the supplementation of different enzyme products could improve AMEn, digestibility and performance of the broiler chickens fed the lupin-based diets. From the results obtained, it can be concluded that improvements in the measured parameters were seen with some of the enzymes. Gal-I, and Gal-II in combination with lactase were the most efficient enzymes concerning improvement in the AMEn of these diets, which was consistent with the performance data. Gal-I (diet E) increased the AMEn significantly compared to the lupin control diet, and reached a level not significantly different from the AMEn of the diet A (non-lupin diet).
