Layer feed for preventing chicken white crown disease

Abstract

The invention discloses a layer feed for preventing chicken white crown disease. The layer feed is prepared from a main material of the feed and traditional Chinese medicine additives, wherein the main material of the feed is prepared from the following components in parts by weight: 400-600 parts of corns, 20-80 parts of rice bran, 1-5 parts of lard oil, 200-300 parts of bean pulp, 10-30 parts ofrapeseed meal, 50-100 parts of crude calcium powder, 5-15 parts of calcium hydrophosphate, 1-3 parts of sodium chloride, 0.5-1 part of choline chloride, 0.1-0.5 part of lysine, 1-2 parts of methionine, 0.1-0.2 part of overflow polyenzyme, 0.1-0.2 part of oregano oil, 5-15 parts of premix, 0.1-0.3 part of an antioxidant and 0.5-1 part of a mildew preventive. The main material of the layer feed isreasonable in collocation, and meets the physiological needs of layers; traditional Chinese medicines are added into the main material of the layer feed, so that the layer feed not only can be used for preventing the chicken white crown disease, but also can help digestion and improve appetite, and can enhance the immunity of chickens and adjust the gastrointestinal function of the chickens.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a layer hen feed for preventing white crown disease. Background technique [0002] Chicken white crown disease is a kind of intracellular parasitic protozoan disease caused by Leukocystosis carinii. Chickens of various ages and varieties can be infected, with the highest incidence rate in 3-6 week-old chicks, and the mortality rate in severe cases can be as high as 50%-80%. It is characterized by anemia, diarrhea, generalized hemorrhage, decreased egg production, and slowed weight gain. The disease occurs frequently in summer and autumn, and is one of the main diseases that endanger the chicken industry. [0003] The pathogen of this disease is Leucocytos carinii, and its occurrence is directly related to the epidemic and the activities of Culicoides. The disease is spread widely in almost all chicken-raising countries in the world. At present, the most commonly used method to...

Problems solved by technology

At present, the most commonly used method to treat this disease is to directly feed traditional Chinese medicine and anti-parasitic drugs. Due to the unreasonable formula of traditional Chinese medicine or simply crushed, the particle size is too large and the drug release is slow, resulting in low bioavailability , the clinical effect is not very good; and various anti-parasitic drugs such as compound timethazine, sulfaquinoxaline, prohexidine, and pyrididine have been used repeatedly for a long time, resulting in the resistance of the pathogenic microorganisms to the drugs. The curative effect is reduced, and the drug remains in the animal products, which cannot meet the pollution-free requirements, and affects the export of livestock and poultry products and people's health
