Evaluation in terms of Animal Nutrition of Fish Meal Produced in Different Regions of the Black Sea Region in Türkiye

Abstract

Fish meal is obtained as a result of the processing and drying of fish that are not suitable for human consumption and the wastes left in the fishing industry, or by passing them through various technological processes. Fish meal, one of the two main products of the fishing industry, is used in feeds as a protein source with high digestibility with its high content of amino acids, vitamins, and minerals. Fish meal is one of the most important features that makes it superior to other feed raw materials due to the essential amino acids and long-chain polyunsaturated fatty acids it contains. With the addition of fish meal to the ration performance and immune system of young animals are positively affected. It is stated that fish meal can be added 3-10% to poultry rations, 5% to cattle and sheep rations, and 10% to pig rations. In Türkiye, a significant part of fish meal and oil production is carried out in the Black Sea Region. In this study, the nutrient content of fish meals taken from four different fish meal production factory in the Black Sea Region was evaluated. Accordingly, the highest values are; dry matter (DM) 95.90% (p<0.0001) and ash 17.20% (p<0.0001) in D factory, crude protein (CP) 73.40% (p<0.0001) in A factory, crude oil ether extract(EE) 11.33% (p<0.01) in B factory, metabolic energy(ME, poultry) 3537.5 Kcal kg-1 (p<0.001) in B factory were determined. It was determined that there was no statistical difference among the factories in terms of linoleicacid and linolenic acid amounts of essential fatty acids (p˃0.01), while palmitic acid, palmitoleic acid and oleic acid levels were found to be significant in B factory (p˃0.001). It has been observed that there is a difference in nutrient contents among the fish meal mostly produced in the Black Sea Region in our country.
