Influencing the phosphorus digestibility from feed mixtures in carp breeding by using phytase enzymes and citric acid
Original language description
The aim of the study was to verify the effect of phytase and citric acid addition on increased phosphorus digestibility from feed mixtures in carp breeding. Feed mixtures have many purposes in carp breeding, but can also be a potential source of water pollution by phosphorus. Five diets were used in this study. Their basis was a commonly used feed mixture KP1. The first mixture was also the control, and the subsequent ones were with the addition of 500 FTU, 1000 FTU, 500 FTU and 3% of citric acid and the last one was with the additiion of 1000 FTU and 3% of citric acid. Six tanks, with seven pieces of common carp in each, were prepared for the study. The test was conducted in two repetitions. Excreta samples were collected during the test, and later analysed for phosphorus content. The obtained result have shown a significantly high influence of phytase and citric acid addition on phosphorus digestibility (factorial ANOVA: F = 51.4, d.f. = 2, p < 0.001), where digestibility of phosphorus increased by almost 30%.Furthermore, the amount of phytase in diets had no positive effect on the quantity of the digested phosphorus.
