INVESTIGATION OF THE EFFECT OF THE PREBIOTIC "СEOBALYK" ON THE CHEMICAL COMPOSITION AND NUTRITIONAL VALUE OF THE MEAT OF CLARY CATFISH

Abstract

The article presents the results of a study of the chemical composition and nutritional value of Clary catfishes meat grown in the conditions of the natural hot spring of Chongzhi in the Almaty region while using the prebiotic "Ceobalyk" as part of the main diet. Three groups of fish were formed, which were kept in pools. Prebiotic "Ceobalyk" developed on the basis of a domestic natural mineral zeolite. A prebiotic was added in an amount of 5% to the feed of the 1st experimental group of fish and to the feed of 2nd experimental group-10% of prebiotic was added. To the diet of the control group the prebiotic was not added. Laboratory tests were carried out in accordance with the standards of the Republic of Kazakhstan and interstate standards.

The results of the studies indicate a high content of protein and ash in fish that received the main diet with a prebiotic. The amount of protein in the control group was 15.2g/100g, which is 4.4% lower than in the second group and 8.9% lower than in the third group (p>0.05). The average amount of ash in the third variant was 1.5g/100g, where prеbiotics were used in an amount of 10% to the main diet. This indicator was 2.6% higher compared to the control group. The moisture and dry matter contents in the experimental groups practically did not change. The results obtained allow us to conclude that the use of this prеbiotic in the production of high-quality fish products is promising.
