Problems solved by technology

The clinical symptoms of the model constructed by the above method are not obvious enough, and it needs to be investigated through indicators such as chick weight gain rate, feed intake, water intake, mortality, serum urate content, kidney pathological changes, etc. The steps are cumbersome and need to be further improved

Abstract

The invention discloses a rapid construction method of a chicken mottled kidney model. According to the method, 1% ammonium chloride and 2% polyethylene glycol-400 are added to drinking water for 50 to 120-day-old SPF (specific pathogen free) chicken and added continuously for 10-15 days, and the chicken freely drink water and forage; the chicken mottled kidney model is determined to be successfully constructed if the model chicken have the symptoms as follows: cockscombs and wattle of the model chicken suffer from cyanosis, and claws of the chicken are dried up and dehydrated; the kidney swells and is mottled on the basis of necropsy, and a large amount of grey white urate deposit in ureters. The model constructed with the method has remarkable clinical symptoms and typical necropsy characteristics and is suitable for research of a medicine for preventing and treating the chicken mottled kidney.

Description

technical field [0001] The invention relates to a method for constructing a chicken disease model, in particular to a method for rapidly constructing a chicken mottled kidney model. Background technique [0002] In recent years, due to the excessive pursuit of growth rate and feed-to-meat ratio in the meat and poultry industry, high-protein and high-energy feeds are generally used, and broiler metabolism produces a large amount of uric acid, which increases the burden on the kidneys. If raw materials such as poor-quality cake, meat and bone meal, and moldy corn are used in the feed, and the stocking density is high (35kg-45kg / m 2 ), poor ventilation, renal-type infectious bronchitis virus infection, long-term heavy use of chemical antibiotics, etc., can easily cause kidney damage, block the excretion of a large amount of uric acid, accumulate in the kidney to form urate, cause kidney swelling and bleeding, mottled , Severe cases can cause the occurrence of gout. According ...
