Abstract:
This study was carried out to assess the growth performance, carcass characteristics, serum biochemical and haematological profiles of broiler chickens fed dried bakery waste (DBW)- based diets. A total of 240 day old bird was randomly assigned to six dietary treatments of 40 birds per treatment and 10 birds per replicate in a Completely Randomized Design experiment. The experiment was divided into two phases: the starter phase (from day-old to 4weeks of age) and the finisher phase (from 5weeks to 8 weeks of age). Two standard diets were formulated to meet the nutrient requirements of broiler chickens both at starter and finisher phase. At each phase, maize was replaced with DBW in the diets at 0, 10, 20, 30, 40 and 50% respectively. Dietary garlic supplementation was at 5 g/kg diet. Data were collected on feed intake, weight gain and feed conversion ratio. At the end of the finisher phase, 2 birds per replicate making 8 birds per treatment were randomly selected, tagged, weighed and sacrificed for carcass characteristics. Blood samples were collected for haematological and serum biochemical variables determination. Results revealed that there were significant (P ? 0.05) differences among the levels of inclusion. The live weight, dressed weight and eviscerated weight were not significantly (P ? 0.05) influenced except at 10% DBW replacement level. The results show that there were significant (P ? 0.05) differences between the thighs, drumsticks, wings, shanks, heads, chests and backs. Organs show significant (P ? 0.05) difference in the spleen, gizzard and proventriculus. However, the liver, heart, kidney, lungs and pancreas were not significant (P ? 0.05). It was concluded that dried bakery waste up to 50% level of inclusion in the feed of broiler chickens does not have any harmful effect on the haematological and biochemical profiles of broiler chickens and it will also reduce the cost of production as maize replacement deficit.
