Abstract

The study was performed to assess using burned bone meal as an organic and di-calcium phosphate as an inorganic phosphate source with different amounts of calcium in diet of broiler chicken (Ross-308). The experimental diets involved supplying overall available phosphorus in the form: (1) di-calcium phosphate (14% available phosphorus and 23% calcium), (2) di-calcium phosphate (18% available phosphorus and 23% calcium), (3) burned bone meal (12% available phosphorus and 32% calcium), (4) burned bone meal (14% available phosphorus and 32% calcium), and (5) burned bone meal (16% available phosphorus and 32% calcium). A completely randomized design consisting of five treatments and three replicates was used. The data were statistically analyzed using the Proc GLM model in SAS version 9.1. The results indicate that the source of phosphorus used in the diets affects performance and bone characteristics of the broilers. The chickens fed overall available phosphorus by di-calcium phosphate (14% available phosphorus and 23% calcium) had the best performance which with regards to economic and environmental interests that dictate phosphorus be held to minimum levels, is a promising outcome. The bone characteristics results revealed that the chickens fed with the inorganic source of calcium with a higher amount of phosphorus had the best performance. Thus, the bone meal requires a slightly higher amount of phosphorus than that required for growth performance of broilers.
