    EFFECTS OF FEEDING DRIED CAFETERIA FOOD LEFTOVER AS A PARTIAL REPLACEMENT OF MAIZE ON FEED INTAKE, GROWTH PERFORMANCE, AND CARCASS CHARACTERISTICS OF COBB-500 BROILER CHICKENS
    (Hawassa University College of Agriculture, 2020) OLIYAD GELAN BUTA
    The current study was conducted to evaluate the effect of feeding dried cafeteria food leftover (DCFL) as a partial replacement of maize on feed intake, growth performance and carcass characteristics of Cobb-500 broiler chickens. The DCFL was mixed with other feed ingredients as a partial replacement of maize at 0% (Control diet, T1), 5% (T2), 10% (T3), and 15% (T4). After two weeks of brooding, one hundred sixty unsexed Cobb-500 broiler chickens were weighted and randomly allocated into four treatment diets in a completely randomized design with four replicates of 10 chickens each. The experiment lasted for 49 days exclusive of brooding period, during which feed intake and body weight were measured on daily and weekly basis, respectively. At the end of the feeding trial, two birds (one male and female) that had closely similar live weights to the rest of the birds were selected from each replicate and slaughtered to evaluate the carcass characteristics. The results indicated that the average daily feed intake (g/chicken) was 108, 109, 110, and 110 for those chickens fed on T1, T2, T3, and T4 diets, respectively. Chickens reared on control diet had the lowest final body weight (1790g) when compared to those of T2 (1834g), T3 (1867g) and T4 (1914g). Comparatively the better feed conversion ratio (kg feed/kg weight gain) was recorded with chickens fed on T4 (2.77) as compared to those chickens fed on T1 (2.93), T2 (2.89), and T3 diets (2.85) and differed (p<0.05) from each other. Male chickens had (p<0.05) higher values for all carcass components than females except for wings. Chickens fed with T4 had higher breast meat, thighs, drumsticks and keel bone meat values than those of T1. The highest values for thighs, and drumsticks were observed in chickens fed with T4 diet and differed (p<0.05) from those of T1, T2 and T3. The highest dressing percentage was observed in chickens reared in T4 (68.1%) followed by T3 (66.8%) and differed (p<0.05) from those fed with T2 (64.2%) and T1 (63.7%). From the present result, it can be concluded that DCFL can be included up to 15% in the broiler diets by replacing maize provided it is available in a continuous supply with large quantity.
