Feed additive for controlling bacterial body-surface ulcer disease of pelteobagrus fulvidraco

Abstract

The invention provides a feed additive for controlling bacterial body-surface ulcer disease of pelteobagrus fulvidraco. The feed additive comprises the following raw materials (by weight): 60-80% of a plant herbal bacteriostat, 2-4% of L-Ascorbate-2-Monophosphate, 2-3% of vitamin E phosphate, 2.5-3.5% of vitamin A, 3.0-6.0% of zinc picolinate, 4-6% of taurine and 5-15% of corn protein meal. The ingredients have a synergistic effect and can achieve the purpose of preventing bacterial body-surface ulcer disease of pelteobagrus fulvidraco. In addition, the raw materials have abundant sources and contain no antibiotic. Thus, the product is safe, harmless, green and environment friendly.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of aquatic feed additives, in particular to a feed additive for preventing and treating bacterial body surface ulceration of yellow catfish. [0003] 【Background technique】 [0004] Yellow catfish, of the order Siluriformes, of the family Scorpionidae, of the genus of yellow catfish, is distributed in the Yangtze River, Yellow River, Pearl River, Heilongjiang and other watersheds. It is a common carnivorous bottom dwelling fish in rivers and lakes in my country. Although the individual is small, it grows slowly , but because it is a high-quality freshwater fish with high nutritional value and medicinal value, it is increasingly popular among consumers. With the expansion of intensive farming scale and the improvement of farming technology, the breeding benefits of yellow catfish are very considerable. However, affected by factors such as weather, water quality, high-density breeding, drugs, human operation, st...

Problems solved by technology

The incidence rate is generally 30-50%. Once the disease occurs, the infection will be very fast. If it is not controlled in time, the mortality rate will be as high as 50%, causing huge economic losses to farmers.

[0005] To treat bacterial body ulcer disease, farmers often choose antibiotics for treatment. Although the infection rate can be reduced to a certain extent, the occurrence of the disease has caused economic losses to farmers. In addition, antibiotics have the disadvantages of drug resistance and easy residue. Long-term use of antibiotics can easily lead to disturbance of the intestinal flora of yellow catfish, and at the same time bring hidden dangers to food safety. Therefore, the combination of prevention and control can effectively reduce the risk of breeding
