Compound feed capable of preventing streptococcal diseases of Tilapia and preparation method of compound feed

Abstract

The invention discloses a compound feed capable of preventing streptococcal diseases of Tilapia and a preparation method of the compound feed. The feed comprises the following components in percentage by weight: 4-8% of fish meal, 22-28% of soybean meal, 4-8% of sesame seed meal, 12-16% of corn flour, 8-10% of cotton seed cakes, 15-18% of peanut kernel meal, 13-17% of whole wheat flour, 1-2% of calcium dihydrogen phosphate, 2-4% of a premix, 1-3% of soybean oil, 0.2-0.5% of plantain herb, 0.2-0.5% of common andrographis herb and 0.2-0.5% of large bamboo leaves. The compound feed disclosed by the invention is used for breeding the Tilapia at an adult fish period, and is balanced in nutrition and reasonable in compounding ratio; Chinese herbal medicine components including the plantain herb, the common andrographis herb, the large bamboo leaves and the like are particularly added, so that the health of intestinal tracts of larval Tilapia can be effectively protected, the liver functions of the Tilapia are strengthened, the immunity of Tilapia bodies is enhanced, the capacity of the Tilapia for resisting the streptococcal diseases is improved, and the growth is promoted.

Description

technical field [0001] The invention relates to a tilapia compound feed, which belongs to the technical field of fish feed, in particular to a compound feed for preventing tilapia streptococcosis and a preparation method thereof. Background technique [0002] With the gradual expansion of the scale of tilapia farming, the occurrence and harm of various infectious diseases have also increased significantly, especially streptococcal disease, which has been widespread in recent years and has been increasing year by year. It is highly infectious and has a mortality rate of 50-50%. 70%, has seriously jeopardized the healthy development of China's tilapia aquaculture industry. [0003] Diseased tilapias generally have deep damage to the liver, and the apparent symptoms of flowery liver, pale color, green liver, and swelling indicate that the liver function of the diseased fish is seriously lost, and the disease resistance is seriously lacking. It is irreversible, and it also lead...

Problems solved by technology

[0003] Diseased tilapias generally have deep damage to the liver, and the apparent symptoms of flowery liver, pale color, green liver, and swelling indicate that the liver function of the diseased fish is seriously lost, and the disease resistance is seriously lacking. It is irreversible, and it also leads to the fact that once streptococcal disease breaks out, it is difficult to find effective treatment measures. Therefore, for streptococcal disease, prevention is more important than cure. Through daily health care work, the liver function of tilapia can be enhanced to improve the health of tilapia. Resistance to streptococcal disease is important
