| Abstract | Feed additives were obtained using high-temperature hydrolysis in a thin layer and subsequent fermented hydrolysis. In this work, we studied some biochemical properties of biologically active feed additives obtained from raw materials from poultry waste containing keratin and collagen. There were studied the molecular-mass distribution of peptides in samples of biologically active feed additives and found that the bulk of them are represented by low molecular weight peptides with a molecular weight of less than 5 kDa, and the largest share of this fraction is contained in the feed additive from keratin-containing raw materials (91.5%). The antioxidant capacity of the hydrophilic fraction of feed additives concerning the peroxyl radical varies between 142-219 ?mol TEQ/g. When studying AOE in poultry meat during storage at +4?? for 5 days, it was found that the main differences in AOE in poultry meat samples during storage relate to indicators in the pectoralis muscle of the bird, where the increase in AOE at 38 days of age when using dietary intake No. 3 amounted to 13.7%, and in 49 days of maintenance 67.9% of the AOE in the control group. Consequently, the use of biologically active feed additives in the diet of poultry instead of fishmeal contributes to an increase in the antioxidant capacity of meat and its better preservation. |
