عنوان انگلیسی Effects of multi-enzymes supplementation to wheat and soybean meal-based feeds on growth performance, digestibility and carcass characteristics of quails
چکیده انگلیسی مقاله Japanese quail (Coturnix coturnix japonica) is a popular experimental animal model in scientific research. The present study investigated the effects of dietary multiple enzyme supplementation on growth performance, carcass characteristics, nutrient digestibility and small intestinal histomorphology in quails fed diets based on wheat and soya bean meal. A total number of 192 1-day-old quails were assigned to three treatments with 16 replicates in each and four quails per replicate for 38 days.  The control group received a basal diet, and the treatment groups received a basal diet with 0.10 or 0.20% multi-enzyme, respectively. Growth performance parameters, carcass characteristics, nutrient digestibility and small intestinal histomorphology in quails were evaluated. Dietary supplementation of multi-enzymes to diet significantly increased body weight gain and improved the feed conversion rate. Moreover, quails fed with 0.10 or 0.20% multi-enzymes showed better ash digestibility coefficients and apparent metabolizable energy coefficients than the control quails. Furthermore, quails fed on a diet containing 0.20% multi-enzyme had the highest crude fiber digestibility. The villi length and the villi length/crypt depth ratio of the duodenum were significantly increased and the crypt depth was decreased in quails-fed diets supplemented with both multi-enzyme levels. However, feed consumption, carcass yield, carcass weight, heart weight, gizzard weight, liver weight and total intestine weights were not affected by treatments. In conclusion, our results showed that dietary supplementation of multi-enzymes to a wheat and soybean meal-based diet enhanced the growth performance and nutrient digestibility of quails.
