Increased Immune Response of Carp (Cyprinus carpio L) by Giving Garlic (A. sativum) powder extract

Abstract

Cultivation by utilizing the stocking density and feed used is a driving force for the emergence of diseases due to decreased water quality due to the deposition of organic material from leftover food or fish excretion. Meanwhile, fish become stressed so they are vulnerable to disease attacks, especially infectious diseases such as those caused by bacteria or viruses. One of the natural ingredients that can enhance non-specific immune responses and fish growth is garlic powder. garlic is one of the natural plants which contains active ingredients such as sulfur compounds: alliin, allicin, disulfide, trisulfide; Enzymes such as Alinase, perinase; amino acids like arginine, and minerals like selenium. Allicin is one of the active substances that can kill pathogens (antibacterial) such as Aeromonas bacteria. While alliin contained in the white bottom can significantly improve the fish’s immune system so that garlic can be used as an efficient immunostimulant. The study was conducted using the experimental method. The addition of garlic in this study was: treatment A (0 g/kg of feed), treatment B (5 g/kg of feed), treatment C (10 g/kg of feed), treatment D (15 g/kg of feed), Treatment E (20 g/kg of feed) and Treatment F (25 g/kg of feed). The design used was a completely randomized design (CRD) with 6 treatments and 3 replications. The main parameters observed were the increase in non-specific immune responses including total leukocytes and phagocytic activity and added with absolute growth parameters. As supporting data water quality measurements are also carried out.
