Abstract :

An experiment was conducted to evaluate the efficacy of exogenous enzymes supplementation (ES) on performance, carcass traits and some blood parameters of broilers chickens. One hundred and eighty day old chicks with 40 ± 2 g initial body weight in a completely randomized design with 3 treatments and 4 replications were fed experimental diets included, 1) basal diet no enzymes (control), 2) basal diet + Rovabio® multi enzymes and 3) basal diet + Kemin® multi enzyme. The diets of all groups were formulated in an isonitrogeous and isoenergeticdietbased on corn and soybean. Data on feed consumption, weight gain, feed conversion ratio, carcass characters, high density lipoprotein (HDL), low density lipoprotein (LDL), cholesterol and triglyceride levels were collected for 3 periods starter (1-21 d), grower (22-42 d), finisher (43-49 d) and total (1-49 d). Results showed significant differences (P<0.05) among different experimental diets for weight gain, feed intake and feed conversion ratio. The lowest feed consumption and weight gain were observed in control group while the highest were obtained in groups that fed with multi enzyme supplementation. Also, poor feed conversion ratio (FCR) was observed in control group and best FCR (lowest) were in groups that were fed multi enzymes. In carcass traits no differences (P>0.05) between groups were observed. Adding enzyme significantly increased the concentration of blood HDL and decreased triglyceride, cholesterol and LDL at 21, 42 and 49 d of age (P<0.05). Results from this experiment suggest that multi enzyme supplementation can improve broiler performance.
