The adjustment of dietary nutrients has a good effect on the prevention and control of coccidiosis. Dietary Protein Formulation Protein-rich diets increase the mortality of chickens infected with Eimeria tenella and increase the oocyst production of E. avenae-infected chickens, while low-protein diets reduce the incidence of coccidia. Disease; semi-pure nutrient diet without bean cake significantly reduces the mortality and lesions of coccidiosis in chickens. Adding crude soybean meal can reduce chicken infection to all Eimeria. 2 Unsaturated Fatty Acids in Diets The unsaturated fatty acids have a certain ability to resist Eimeria tenella, the most common being linolenic acid (main source is linseed oil), eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) (the main source is fish oil). American researchers Danforth and Allen have found that adding 2,5% to 10% of fish oil, 10% of linseed oil, or 10% of linseed oil to feeds, after inoculating coccidiosis vaccine to chickens, compared with feed without this additive The chicken cecal lesions of E. tenella were acutely reduced and the weight gain was maintained. Microscopic histology of infected chickens was found to reduce invasion and development of the worms. It has also been found that high feed fatty acids cannot protect chickens from infection with E. maxima parasitizing in the middle small intestine. The vitamin E in the diet of vitamin E could reduce the reproduction rate of E. tenella by 51%, but it obviously stimulated the reproduction rate of E. amylova up to 213%. Vitamin E is important for coccidia, but when chickens are infected with E. tenella, adding 100 IU of vitamin E per kilogram of feed can reduce mortality and increase weight gain. Vitamin A can promote the recovery of coccidiosis. Adding 17,600 IU of vitamin A per kilogram of feed to the chickens infected with Eimeria tenella, E. tenella and E. tenella was found to have a similar promoting effect on chicken growth and appetite. Rational Compatibility of Betaine in Diets Betaine is a pro-vitamin found in various living organisms. Betaine enhances the activity of various anticoccidial drugs. The combination of betaine and salinomycin can promote the weight gain and feed conversion rate of coccidia-infected chickens, reduce intestinal lesions, and reduce mortality. In the absence of anticoccidial drugs, betaine significantly inhibited the encroaching effects of coccidia. The use of salinomycin alone, the inhibition of the invasive effect of the program t tank. Same as betaine alone. The effect of betaine may not only be the inhibition of coccidia infestation and development, but may also include enhancement of the integrity and function of the gastrointestinal tract, so that chickens can overcome coccidiosis infection. Carbohydrates are formulated similarly to chickens and coccidia needs carbohydrates, mannose can not change the excretion of oocysts, given lactose, starch or D-fructose chicken, the oocyst excretion increased significantly; feeding sucrose chickens, The oocysts excreted a larger amount. When the diet contains maltose, glucose, amylopectin, the chicken's coccidial oocysts excrete the largest amount; and maltose, glucose, amylopectin can form a nutrient reserve in the coccidia.
