Efficiency of Different Iranian Commercial Dicalcium Phosphates (Dcps) Supplements in Broiler Performance

With attention to quality variations in commercial Dicalcium phosphates (DCPs) and their P bioavailability, aim of this study was to comparison of DCPs purchase from different Iranian factories in broiler grow performance. 256 male chickens (28-day old) were randomly selected for this experiment. 8 chickens with approximately same weight were placed in per cage. The rations were formulated according NRC-1994, and supplemented with DCP supplements were purchased from eight different factories; Iran phosphate, maden khojasteh, puya khojasteh, golbarshimi, danrazi kimiya, telavang, lianshimi, partotabesh and their have grouping respectively as A, B, C, D, E, F, G and H. finally, experimental DCPs haven’t significant effects on chickens feed intake during 4-6w, 6-8w or 4-8w of rearing period. Various DCP supplements hadn’t significant effect on weight gain at 4-6wand 6-8wold chickens. There is difference between treatment 1 and 6 with treatment 7. DCP supplements hadn’t any significant effect on FCR at 4-6-w-old chicks. But DCP treatments have significant effect on FCR at 6-8or 4-8-w-old chicks. It is concluded, when aims of broiler production are more meat yield and lower FCR, in other words DCPs are effective feedstuffs for performance of chicken.
