Abstract

The objective of this study was to determine the relative biological value of several different Di-calcium Phosphates (DCPs) produced in Iran. The samples of DCPs were randomly taken from the final product of 26 domestic DCP production factories that were active at the time of the study in 12 different provinces. After analyzing and determine the standard indices, only 7 samples of Di-calcium Phosphate which had the national standard were chosen. Seven hundred and twenty day-old male Ross 308 broiler chicks were purchased and randomly divided into 8 dietary treatments with 6 replicates of 15 birds in each. The birds were kept and reared in battery cage system for 21 days. Phosphoric acid (85%) was used to provide the phosphorus in control and different DCP samples were included as the source of phosphorus in other treatments. Body weight gain, feed consumption, and feed conversion ratio were calculated on days of 10 and 21. At the end experimental period (21 days) the amount of ash, calcium and phosphorus of tibia Bones was measured. There was no significant difference between control and experimental treatments in terms of the production indices on 21 days of age, but a significant difference was observed in body weight gain between control and treatment F on 10 days of age. There was no significant difference in Bone ash content of control and experimental treatments. The amounts of tibia calcium were significantly lower in treatments F and G than those of control. Amount of Bone phosphorus in B, C, F and G treatments were significantly lower than control. The relative biological values of the experimental samples (DCPs), according to two indices of body weight gain and Bone ash for the samples of Di-calcium Phosphate A, B, C, D, E, F, and G were estimated 98. 1, 103. 3, 96. 9, 100. 2, 97. 9, 94. 0, and 100. 2 percent, respectively. According to the results of this study it could be concluded that some of the domestic DCPs had not the necessary standards, while some of them have high and acceptable biological value.
