Effects of Supplementation of Zinc, Manganese, or Copper and Different Phytase Levels in Serum and Bone Acid and Alkaline Phosphatases of Broiler Chicks

The knowledge of biological trace minerals and phytase requirements for modern broiler genotypes is not established the pressure to reduce their usage in animal feeding due environmental issues increasing. Here, alkaline phosphatase (ALP) tartarate-resistant acid (TRAP) tibia serum broilers fed with diets containing various levels reduced zinc, manganese, copper was evaluated. experiment performed using 1,200 male Cobb raised according standard commercial husbandry techniques. Data were analyzed as a 4×3 factorial arrangement four concentrations zinc (0.34, 0.49, 0.64, 0.79 ppm), manganese (0.18, 0.43, 0.68, 0.93 or (0.09, 0.12, 0.15, 0.18 ppm) three (0, 500, 1,000 FTU/kg) age periods 1-21 36-42 days. While dietary supplementation did induce significant effect bone tissue biochemical markers, TRAP activity 42-day old increased higher levels. Increasing linearly ALP growth, suggesting that essential longitudinal growth. Phytase significantly promoted increase activities, growth plate activity, accelerated calcification, remodeled newly formed into trabecular bone. Although every enzymatic affected by treatments, use, along minerals, improved response rapid required nowadays provided nutrients adequate metabolism.
