Effects of Bone Ash, Rock Phosphate and Di Calcium Phosphate on Carcass Characteristics and Organoleptic Properties of Broiler Chickens

Abstract

This research was conducted to investigate the utilization of rock phosphate as an alternative phosphorus source to bone meal and dicalcium phosphate in broiler diet. The attempt was to put to use locally available sources of phosphorus in poultry production. A total of 250 Sayed broiler chicks were purchased at day old and brooded. After brooding, 210 very active and health ychicks were allotted at random to 3 dietary treatments, each with 5 replicates such that 14 birds were assigned to each replicate and a total of 70 birds made up a treatment. Data collected were analyzed using SPSS statistical software. The result had significant(P <0.05) differences on drumsticks, neck, wings, thighs and no significant (P >0.05) differences across treatments for all internal organs examined. This study showed that, at 2.5 Kg per 100 Kg diet, rock phosphate can be utilized without adverse effect on carcass and internal organs characteristics. This also means that diet containing rock phosphate can compete favourably with bone ash which serve as a control and therefore safe for broiler chickens production. From this finding, it was recommended that, rock phosphate could be utilized without adverse effect on carcass and internal organs of broiler chickens.
