Application of mutmeng essential oil and basil essential oil to prevent necrotic enteritis

Abstract

The invention discloses an application of mutmeng essential oil and basil essential oil to prevent necrotic enteritis. Plant essential oil includes mutmeng pure essential oil, basil pure essential oil or mutmeng-basil compound essential oil. The applicant spends one to two years and successfully builds an animal model of the necrotic enteritis. The model is feed with wheat basal diet, and fish meal is added in a later period; clostridium perfringens is adopted to counteract toxic substances independently, and typical pathological changes are obvious; and the previous phenomenon that a coccidium concurrent model and coccidiosis are confused can be excluded. The experiment period is short, and the repeatability is high. In addition to in-vitro experiments, the applicant also takes use of the model to do research on the in-vivo control effect of the plant essential oil, and it is really clear that the plant essential oil has the effects of preventing and curing the necrotic enteritis.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, and in particular relates to the application of nutmeg essential oil and basil essential oil in preventing and treating chicken necrotic enteritis. Background technique [0002] Chicken necrotic enteritis was first discovered by Parish (1961), and it is an acute digestive tract disease caused by Clostridium perfringens, which is a common disease in chickens. Caused annual loss of more than 2 billion US dollars to poultry industry all over the world. In recent years, the European Union banned the addition of antibiotic growth promoters to feed, resulting in a large number of outbreaks of necrotic enteritis in the chicken industry in European countries. [0003] Necrotic enteritis usually occurs after 4 weeks of age and occurs in poultry farming areas worldwide (Long J R, 1973). Clinical symptoms include acute clinical symptoms and subclinical symptoms. [0004] Acute clinical signs of necroti...

Problems solved by technology

In addition, different scoring standards are used, resulting in different scoring systems that cannot be compared with each other

Because the establishment of animal models of chicken necrotic enteritis is relatively complicated, most of the current researches have only been tested in vitro, but not in animal models.

The results of only in vitro tests often cannot truly reflect the prevention and treatment effect of the tested drug on chicken necrotic enteritis
