Compound Chinese herbal medicine feed additive for protecting tilapia intestinal health

Abstract

The invention discloses a compound Chinese herbal medicine feed additive for protecting tilapia intestinal health. The compound Chinese herbal medicine feed additive comprises the following components in percentage by weight: 18-25% of astragalus membranaceus, 15-18% of wild Chrysanthemum, 4-7% of longhairy antenoron herb, 9-15% of ephedra sinica, 16-19% of bighead atractylodes rhizome, 20-30% of Chinese angelica and 5% of liquorice. According to the compound Chinese herbal medicine feed additive, the intestinal health of tilapia can be improved, the digestive absorption ability of tilapia can be improved, the survival rate can be improved, the food coefficient can be reduced, and the water quality pollution can be reduced.

Description

technical field [0001] The invention relates to a feed additive, which belongs to the technical field of cultured fish feed, in particular to a compound Chinese herbal medicine feed additive for protecting the intestinal health of tilapia. Background technique [0002] Tilapia, commonly known as African crucian carp, is a cultured species recommended by the Food and Agriculture Organization of the United Nations to the world. It is an important freshwater cultured fish and is known as one of the main sources of animal protein in the future. The annual tilapia farming in China is as high as 1.2 million tons, accounting for 60% of the world's farming volume. At present, it is mainly concentrated in Guangdong, Guangxi and Fujian. The intensive farming of tilapia is the "one fish, one shrimp" in Guangdong Province. "One of the pillars of the industrial chain is also one of the main breeding industries in coastal areas such as Guangxi and Fujian. [0003] However, with the expan...

Problems solved by technology

[0003] However, with the expansion of intensive aquaculture area and the increase of aquaculture density, the disease problem of tilapia is becoming more and more serious, especially once the intestinal disease breaks out, it is highly contagious, lasts for a long time, and has a high mortality rate, which often causes tilapia. A large number of fish died, causing serious losses to farmers

Research reports show that poor feed quality and unbalanced feed nutrition are one of the causes, especially when the feed nutrition is unbalanced, excessive nitrogen discharge will easily cause high ammonia nitrogen and low dissolved oxygen in the water body, which will affect tilapia larvae especially serious
