Reuse of broiler chickens
In general, when broiler chickens are raised to 70 weeks of age, the egg production rate should be eliminated when the egg production rate drops to 30%. However, if the following measures are taken, the chickens can still recover their egg production capacity and the egg production rate can be increased to 70%. Around, the egg production period was extended for more than half a year. 1. Immunization and deworming The chickens were vaccinated with conventional chicken Newcastle disease i strains, and levamisole was added to the feed to drive off parasites such as digestive tract nematodes. 2. Stop feeding, stop water, and stop feeding 3 days after the immune deworming, but give water and light. After 6 days, the water supply and light were stopped while the food was stopped, and continued for 6 days. The purpose of stopping food and water is to consume excess fat in the chicken body to reduce its weight, and cause it to be deprived of due to lack of nutrition, physical deterioration, and weakness of the body. The purpose of stopping the light is to keep the chicken in a quiet environment, free from external influences, reach a state similar to hibernation, and at the same time prevent chickens from licking each other. 3. Transfer to normal feeding, stopping water, stopping water, stopping for 6 days, then transfer to normal feeding. 4. The effect of the chickens was gradually defeated, and they were basically taken off in 26 days (fins and back without feathers). The weight is generally reduced by about 30%. After two months of normal feeding, one after another began to lay eggs, after about a month or so, egg production can reach a peak (the egg production rate is about 70%), and the laying period can be extended by about six months. 5. Precautions 1 To prevent chicken from eating foreign objects. It is best to use cages. If you raise them flat, the floor and walls should be kept clean. 2 The density should be reasonable. Feeding according to conventional feeding density, over-dense can easily lead to chickens licking each other. 3 In the spring and summer season, attention should be paid to the elimination of mosquitoes and flies, and winter should be kept warm.
