.Impact of fed corn based diets substituted with graded levels of potato chips scraps on growth performance, feeding behavior and economic efficiency of Japanese Quails.

: The experiment was done for assess the utilization of potato chips scraps (PCS) as a substitute with a corn in basal diet on feeding behavior patterns, growth performance and economic e ffi ciency of Japanese quails. A total number of 144 unsexed Japanese quails during age of 14 days were distributed randomly allocated into three treatments with each treatment further subdivided into four replicates. The treatment one received a basal diet as a control, while treatments 2 and 3 had yellow corn replaced with two levels of PCS, i.e., 4% and 8%, respectively. The quail were raised under the same management conditions with ad libitum feed and water o ff ered. Various parameters, such as body weight gain, body weight, feed intake, feed conversion ratio, feeding behavior patterns and economic e ffi ciency were appraised. Our results showed that the birds received (PCS) 4% and 8% higher significantly (p ≤ 0.05) value of body weight gain , body weight, performance index, economic e ffi ciency, intestine length, total lipids, cholesterol, triglycerides and HDL than control group. While, there were no found significant di ff erence between treatments for feed consumption. Moreover, the high (p ≤ 0.05) value of LDL was found in control group than other treatments group. In conclusion, the supplementation of the diet with PCS at the levels of 4% and 8% did not have any adverse impact on the bird’s performance
