Effects of Phytase and Dicalcium Phosphate Supplementation on Growth Performance of Broiler Chickens

Abstract
Phytate is an inactive form of phosphorus that is converted into an active form with the help of the phytase enzyme. This enzyme plays a major role in the digestion of protein/amino acids, energy metabolism, mineral storage, and bone development of chickens during the growth stage. Dicalcium phosphate (DCP) is an important compound among the minerals that has a ratio of active calcium and phosphorus effects of calcium and phosphorus on the growth of broilers, especially in the first stage of life, causing rapid growth. This experiment was conducted to study the comparative effect of supplementing phytase enzyme and DCP on the growth performance of broiler chickens in 28 days. All (150) one-day-old chickens were randomly divided into five equal groups, and each had 3 replicates. 30 birds in each group and (10) chicks in each replicate. The control (basal diet) and Treatment 1: 1000 IU/Kg phytase with starter fed (first 14 days), Treatment 2: 1000 IU/Kg phytase from the first day to the last day of the study, Treatment 3: 15 gr/Kg DCP with starter fed (first 14 days), and Treatment 4: 15 gr/Kg DCP from the first day to the last day of the study. The experiment showed that the T2 group gained 1010 g significantly (P < 0.01) more weight than all other groups. The feed intake was lower and had a significant (P < 0.01) food conversion ratio (FCR) as well. It can be concluded that the addition of 1000 IU/kg phytase enzyme in the feed of broiler chickens has efficient and significant results on their live body weight, weight gain, FCR, and feed intake.
