A feed additive for preventing and treating nutritional hepatobiliary syndrome in seawater cultured fish

Abstract

The invention discloses a feed additive for controlling nutrition-based hepatobiliary syndrome of marine-culture fishes, comprising the following ingredients which take the additive amount of each ton of the feed as reference based on purified products: 800-1500 g of vitamin E, 400-1000 g of L-carnitine, 600-2000 g of bile acid, 10-30 g of vitamin B1, 15-30 g of vitamin B2, 15-30 g of vitamin B6,2-10 g of folic acid, 120-800 g of inositol, 10-50 g of anti-oxidant, and 2000-8000 g of defatted rice bran with the fineness of 80 meshes. The long-term culture experiments of bass, large yellow croaker, sciaenops ocellatus, trachinotus ovatus, grouper and other marine fishes prove that the feed additive has good effects of treating or controlling the hepatobiliary syndrome of various high density marine-culture fishes, and the main components of the feed additive are nutrient components required by marine-culture fishes, so that the feed additive has safety and high efficiency for long-termuse with no toxic or side effect, and the cultivated fishes have good vitality and grow fast, and high feed conversion rate and good cultivation efficiency are achieved.

Description

Technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing and treating nutritional hepatobiliary syndrome of mariculture fish. Background technique [0002] my country is the world's number one aquaculture country and the only country in the world whose aquaculture production exceeds the catch production. Aquaculture occupies a very important position in the national economy. In recent years, my country's aquaculture has developed vigorously, especially the fourth wave of aquaculture represented by marine fish farming is in the ascendant. However, because the current international and domestic research on marine fish nutrition is not sufficient, most of its feed formulations and additives are based on other similar aquaculture species or based on experience; at the same time, due to incorrect breeding and feeding methods by farmers, At present, the feed coefficient of marine fish is generally high, and diseases such as hepat...

Problems solved by technology

However, due to insufficient current international and domestic research on marine fish nutrition, most of its feed formulations and additives are determined by reference to other similar aquaculture species or based on experience; at the same time, due to incorrect feeding and feeding methods of farmers, resulting At present, the feed coefficient of seawater fish is generally high, and diseases such as hepatobiliary syndrome in seawater cultured fish are common and occur frequently, which greatly reduces the survival rate and economic benefits of seawater fish culture

This situation has seriously hindered the further development of marine fish farming industry
