Sažetak
A 21 day experiment with the day-old broilers was conducted in order to asses the effect of phytase supplementation to different cereals-soybean meal based diets on the nitrogen, calcium, total and phytate phosphorus excretion and retention. Diets were formulated to contain 4 different cereals (corn, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0 %) and 3 levels of supplemental phytase (0, 500 and 1000 PU/kg). Nutrient intake, excretion and retention were determined in the first three days of the 2nd and 3rd week of trial. Increasing phytase level resulted in reducing phytate phosphorus excretion and increasing its retention. Significant differences have been obtained only in the 2nd week (excretion P < 0.024 and retention P < 0.044). Phytase supplementation significantly influenced total phosphorus excretion in the 3rd week (P < 0.048) and retention in the 2nd week (P < 0.015). Effects of 500 and 1000 PU/kg were not statistically different between themselves. No significant influence of phytase supplementation on nitrogen and calcium excretion and retention was observed.
