Abstract

A total of 40 pheasants were used for the experiment. two diets were fed to the birds during the growing-finisher period. The diets were characterized by a different composition of dry matter: metabolizable energy 11MJ/kg = 2620 Kcal/kg and 11.7 Mj/kg = 2800 Kcal/kg, crude fibre 12.2% and 6.2% , crude protein 16.0% and 23.5% for HS and LS diets, respectively. Live weights and gut characteristics were measured in 91 and 133 days old pheasants (weight, volume and lenght of the digestive apparatus with the annexed organs and of the different elements and sections: liver, gizzard, small intestine, caeca and colon-rectum). Blood samples were drawn at 91 and at 133 days and some serum biochemical components were detected in order to establish the metabolic profiles. Results showed that the use of the diet containing 12.2% fibre produced lighter pheasants with longer caeca. The differenriated metabolic profile showed an adaptative answer to the diet with the higher fibre content. Pheasants fed with the higher fibre diet resulted theoretically more adapted to survive in nature after release.
