Abstract


The effect of acidifier (Fysal®) on phytate utilization, mineral digestibility and bone density of broiler finisher chickens was investigated. Three hundred broiler finisher chickens were assigned to five treatment groups each replicated thrice with twenty chickens per replicate in a completely randomized design. Chickens in the control treatment were fed basal diet while those in other treatments were fed diets supplemented with 0.1, 0.2, 0.3 and 0.4% levels of acidifier (Fysal®). At the end of the 56-day feeding period, nine chickens per treatment were selected for mineral digestibility trial and later processed to remove the left tibia bone for determination of bone density. Supplementation of 0.3% organic acid was found to liberate minerals bound by phytate and significantly (P<0.05) increased apparent digestibility of calcium, phosphorus and magnesium by 28.57, 27.77, 13.89% respectively. It also significantly (P<0.05) increased bone density, tibia ash, calcium and phosphorus by 11.69, 11.58, 14.44 and 14.89% respectively. The study conclude that the use of acidifiers at 3kg per ton/feed is beneficial in broiler production for bone mineralization and efficient utilization of feed nutrients.
