COMPARISON OF MEAT OXIDATIVE STABILITY FREE-REARING AND FARM-REARING PHEASANTS

Abstract

The aim of this work was to compare contents of fat and oxidative stability of farm-rearing and free-rearing common pheasant (Phasianus colchicus). For experiment were used pheasants from two types of breeding. The first group came from free-rearing and it was fed by a natural way and in the winter months were fed with wheat, maize and barley. For the experiment analysis were used from free and farm-rearing 10 male of pheasants and 10 female of pheasants. The second group was created by pheasants, which came from farm breeding from VPP Kolíňany farm, Žirany resort. The group of farm-rearing pheasants was reared in farm conditions until the time of hunt (70 days). The pheasants were fed by special feed mixtures (BŽ1, BŽ2, BŽ3) intendent for fattening of pheasants. All pheasants were caught on common hunting in Nitra area. The first meat analyzes were carried out 1 day after the pheasants hunting. Other samples were analyzed after 6 months of freezing storage. The different contents of fat in breast muscle was significant (P0.05) between groups farm-rearing and free-rearing and contents of fat was significant (P0.05) between male and female into group too. The contents of malondialdehyde (MDA) in breast muscle was in range from 0.025 to 0.056 mg.kg-1 at the start of storage (1st day) and at the end of storage (6th month) was in range from 0.113 to 0.197 mg.kg-1. The significant differences (P0.05) in contents of MDA were between male and female from farm-rearing in sixth month of storage. The significant differences (P0.05) in contents of MDA were between group farm-rearing and free-rearing at the beginning and at ending of storage.
