First, preventive measures
1 According to the development of the flock, timely cutting off the crucian carp is generally conducted at 7 to 10 days of age, and cut off the upper 1/2 and lower 1/3, accurately grasp, and once in place. Vitamin C, vitamin K3, and antibacterial drugs can be added to feed and drinking water within 1 to 2 days before and after the break.
2 We must regularly sample and weigh and calculate the evenness. We must group out small and over-sized chickens, raise the amount of feed or limit feeding, in order to improve the uniformity of the development of the entire flock so as to ensure that every A chicken can weigh more than 5% to 10% of its standard body weight before the start of production. Otherwise, the feeding time of the bred material can be prolonged and the increase of light can be delayed.
3 In the early stage of egg production, proper amount of concentrated cod liver oil is added to increase the content of vitamin A.
4 From 18 weeks of age, use anti-stress medicines, multivitamins, etc. every 2 weeks to enhance the disease resistance and anti-stress ability of the flock. At the same time, strengthen the feeding and management, and create a favorable environment for the flock to facilitate its production. And nutritional conditions.
5 Establish a reasonable immunization program, and strictly follow the correct method on time and in strict accordance with the quantity. It is advisable to add antibiotics and anti-stress medications in drinking water or feed for 3 days before and after each immunization, and to strengthen the management of the temperature, ventilation, and ventilation of the house to minimize any stress so as to ensure chickens. Group normal immune response.
6 before the opening of the best deworming 2 times, commonly used drugs are levamisole, albendazole, etc., in order to avoid parasites after egg production.
7 The replacement of laying hens should have a transitional period so as not to cause excessive nutrients due to excessive speed. Excessive double-yellow eggs cause anal prolapse.
Second, the treatment
1 When an anal chicken is found, the amount of multivitamins in the feed should be doubled first, and 0.05% additional trace elements should be added. Antibiotics should be added to drinking water to prevent secondary infection.
2 Isolation of diseased chickens immediately and keeping them alone. Firstly apply normal saline to heat the anus to reduce congestion and edema, and then use 0.1% potassium permanganate or 1% to 2% boric acid water to wash out the prolapsed part. After drying, apply antibiotic ointment and gently send it into the anus. 1 to 2 hours to facilitate rehabilitation. Early disease can be cured, the more stubborn anorthism can be part of the prolapsed back after the line, the anus suture line, leaving a row of fecal mouth and coated with chlortetracycline ointment, over 2 to 3 days and then Suture mouth removed.
