Effect of feed additives from marine hydrobionts on the protein metabolism condition in broiler chickens

Abstract

There was studied the effect of two feed additives made from finely ground wastes of the primary processing of marine aquatic organisms on the biochemical parameters of the protein metabolism of the blood serum of broiler chickens of Ross 308 cross. The composition of the mineral feed additive (MFA) included mussel leaves and seawater, the protein-mineral feed additive (PMFA) – the leaves of large and the body of small mussels, seaweed Phyllophora nervosa and seawater. The determination of blood serum indices was performed using an automatic biochemical analyzer GBG ChemWell 2910 (USA) and the use of test systems Global Scientific (USA). According to the results of biochemical studies of the broiler chickens' blood serum, the diet of which was supplemented with feed additives, there was established an increase in the total protein content, incl. albumin and globulin. Compared with MFA, the use of PMFA to a greater extent increased the content of total protein, albumin, and globulin. The total protein content changes and its fractions occurred due to an increase in the activity of transamination enzymes: alanine and aspartate aminotransferase and the absence of changes in glucose content. Due to the relatively smaller increase in the amount of albumin compared to globulin, the albumin-globulin ratio in the chickens of the experimental groups was lower. Among the globulin fractions, the greatest changes were observed in the relative content of ά2-globulins. Based on the results of the research, a conclusion was drawn on the stimulating effect of feed additives of marine aquatic organisms on the protein metabolism condition of broiler chickens.
