Biological feed

Abstract

The invention discloses a biological feed. The biological feed consists of the following raw materials in parts by weight: 15-20 parts of camellia japonica leaves, 5-15 parts of maple leaves, 0.5-2 parts of vietnamese sophora root, 5-8 parts of Chinese brake herb, 2-4 parts of prickly pear cactus, 3-6 parts of typhonium giganteum, 2-5 parts of Chinese gentian root, 3-6 parts of cyrtomium rhizome and 2-5 parts of palmleaf raspberry fruit. A preparation method of the biological feed comprises the following steps: drying and crushing the camellia japonica leaves, maple leaves, vietnamese sophora root, Chinese brake herb, prickly pear cactus, typhonium giganteum, Chinese gentian root, cyrtomium rhizome and palmleaf raspberry fruit, and then mixing with corn flour and wheat bran to prepare particles. The biological feed disclosed by the invention has a significant effect in the aspect of prevention of newcastle diseases of chicken, and has the advantages of no toxicity, no medicine tolerance and no medicine residues.

Description

technical field [0001] The invention relates to a feed, in particular to a biological feed for preventing Newcastle disease in chickens; the invention also relates to a preparation method of the biological feed. Background technique [0002] Chicken farming accounts for a large proportion in my country's aquaculture industry, and poultry diseases have always restricted the development of my country's aquaculture industry. Newcastle disease is an acute septic contagious disease caused by Newcastle disease virus (NDV). Commonly known as "chicken plague", the so-called Asian chicken plague. The disease can occur throughout the year, especially in cold and climate-changing seasons. Chickens of various ages can be infected, and chickens aged 20 to 60 days are the most susceptible and have a high mortality rate. The main features are dyspnea, neurological disturbance, mucosal and serosal hemorrhage and necrosis. The main source of infection is sick chickens and infected ...

Problems solved by technology

Although it is not as harmful as highly pathogenic avian influenza, it also seriously affects the healthy development of the chicken industry and the economic benefits of the majority of chicken farmers

[0003] At present, vaccination is mainly used to reduce the incidence of the disease, but vaccination alone is not enough, because in actual production, often due to the interference of various factors such as temperature, environmental stress, drugs and pathogens, resulting in immunity Low state, resulting in poor response of the body to exogenous stimuli, leading to unsatisfactory vaccine immune effect
