Eight measures to prevent Chicken stress
It is reasonable to reduce the feeding density by using a set of equipment to support 100 adult chickens, and the feeding density should be 6-8 per square meter. After fixing the flock, do not casually throw new chickens into the flock.
Careful transfer should be carried out at night. 2-3 days before the transition, an appropriate amount of antibiotics and vitamins should be added to the feed or drinking water. 1-2 hours before the chicken is caught, chlorpromazine should be added to each kilogram of feed, 30 mg per chicken, and 50 mg each for adult and adult chickens.
The meticulous preparation of feed should be based on the age characteristics and nutritional requirements of chickens, the use of high-quality raw materials, and the preparation of full-price diets that meet the requirements.
The gradual replacement of feed requires a transition period of 2-3 weeks, and it is necessary to gradually add new feed and reduce old feed, which cannot be achieved in one step.
The suitable temperature for controlling environmental conditions for adult chickens is 5 ℃ ~ 27 ℃, the humidity is 60% ~ 70%, and the suitable temperature for laying eggs is 13 ℃ ~ 20 ℃. When the natural light is insufficient in winter and spring, artificial light should be supplemented, requiring that the bulb is 2 meters from the ground, the distance between the bulbs is 3 meters, and each bulb can not be more than 60 watts.
Fixed management system feeding, drinking water, turning on the lights, turning off the lights, removing feces, picking up eggs, semen collection, artificial insemination and other time should be fixed as far as possible, and do not change the breeder casually.
Reduce immune stress 3 days before vaccination, supplement or drink anti-stress substances, such as electrolytic multivitamin, vitamin C, fumaric acid, etc.; the action should be gentle during immunization to avoid causing chicken injury or aggravating stress reaction.
Two days before beak cutting stress, vitamin K3 was added to feed and drinking water, 0.4 mg per kilogram of feed or drinking water, and continued to add vitamin K3 and multivitamins to drinking water and feed 2 to 3 days after beak cutting.
