1 cut off
The main purpose is to prevent flea, licking, blood feeding, etc. in the flock. Causes of paralysis: excessive feeding density; excessive indoor light; insufficient troughs and gutters; excessively low crude fibre content; poor ventilation and ventilation and chicken habits. Cuttings are usually performed at 6 to 9 days of age. To prevent excessive hemorrhage in the cuts, 2 mg/kg of Vk can be added to the feed 2 days before breaking, and can be added to drinking water 3 to 5 days after breaking. Multidimensional element.
2 Restricted feeding
The main purpose is to control chicken growth and inhibit sexual maturity. In the case of free-feeding, chickens are over-educated, which not only causes economic losses, but also promotes fat accumulation in chickens and overweight, and affects the egg production capacity in adulthood. Restricted feeding can make sexual maturity timely and synchronous, while saving 10% to 15% of feed. Restricted feeding generally starts from 6 to 8 weeks and ends at 18 to 20 weeks of age.
3 Elimination of low-yielding chickens
In order to save feed and raise the economic benefits of chickens, it is necessary to properly eliminate low-yielding chickens. After 5 to 6 weeks of production, if there are still some chickens that are not yet open, they can be eliminated in time. The elimination of low-yielding chickens should be carried out 40 weeks after the start of production.
4 Regular deworming
Deworming is an important part of feeding and management of laying hens. It can not only reduce feed wastage, reduce feed costs, but also effectively prevent various intestinal parasites in chickens and ensure the healthy growth of chickens. Deworming is usually carried out twice or more. The first one is performed at 7 to 8 weeks of age, and the second is performed at 17 to 19 weeks of age before the chicken is opened. Levomiprofen 25~30 mg/kg can be used as a dressing.
