Assessment of the suitability of triticale in the extruded feeds for table carp

Abstract

Six feed mixtures produced using the extrusion process were tested. The diets were kept at the isonitrogen and isocaloric level, at different share of triticale: from 11% to 57%. Value of the experimental feeds was determined using the chemical methods and analysing the fish growth. The feeding experiment was carried out in concrete tanks. It appeared that triticale was well used by carp. Optimal share of wheat-rye in the feeds was 22%. Utilization of the experimental feeds was satisfactory: the food conversion ratio was 1.43 -1.72 and PER was 2.279 -1.919.
