Abstract

This experiment was conducted to investigate the effect of wheat particle size and dietary enzyme supplementation on performance and carcass characteristics of Japanese quails during an experimental period of 35 d. The experiment was conducted as a 3 × 3 factorial arrangement in a completely randomized design in 9 treatments each replicated 4 times with 20 birds per replicate. The investigated factors were there wheat grain particle size [2, 3 and 3.5 mm] and three levels of dietary enzyme [0, 200 and 400 ppm] supplement. The measured performance traits included: body weight gain, feed intake, feed conversion ratio, carcass yield and abdominal fat. The results showed that the dietary enzyme significantly reduced feed intake and feed conversion ratio (P<0.01). Effect of wheat particle size on feed intake, body weight, feed conversion ratio were also significant (P<0.01). The interaction effect of wheat particle size and enzyme affected significantly feed intake and feed conversion ratio through the experimental period (P<0.01).
