The main points of autumn breeding of laying hens
After the fall, the weather turns cold and old hens enter the late stage of laying. New hens lay their eggs one after another. The following husbandry and management methods are used to allow chickens to produce more eggs and improve economic efficiency.
1. Adjust the flock: Elimination of chickens with fewer egg production, chickens that have lost production, chickens that have stopped production, chickens that are weak, chickens that are severely paralyzed, chickens that have short peaks of egg production, overweight or overweight chickens, and diseases that have no therapeutic value chicken.
2, increase feed nutrition: After a long egg production period and hot summer, old laying hens are already very tired, after the fall should be fed more animal protein feed, add a variety of vitamins in the feed, to prompt the egg chicken to resume production as soon as possible egg. New layer chickens reared in the spring must also provide more nutritious feed to increase egg production.
3, increase the lighting time: After the fall, the natural daylight illumination time is gradually shortened, the layer chickens should be supplemented with light during the egg production. When lighting is supplemented, the ground light intensity is preferably 3 lux. Turn on the lights 2 times a day. Turn on the lights until dawn at 4-5 a.m. for the first time. Turn on the lights until 20-21 when the second time is dark. Turn on the lights during a cloudy day.
4. Forced moulting: Forced moulting can promote simultaneous moulting of laying hens and production at the same time. Artificial forced moulting can take the following approach: Add 2.5% zinc oxide or 4% zinc sulfate to the layer's diet. During the feeding of high-zinc diets, water is kept on, and the light can be reduced to 6-8 hours per day. After 7-8 days, the weight of the chickens decreased by about 25% (eg less than 25% weight loss, and continued to feed high-zinc diets), and the production was discontinued. At this time, the chickens were fed with pre-feeds. On the first day, chickens were fed 30-40. Grams, then add 10 grams per day and increase to 100 grams per day to allow the layer to feed freely. Gradually increase the lighting time to 16 hours per day when normal feeding is resumed.
5, timely deworming: autumn is the best period of laying insects, you can use the following drugs to deworming: (1) levamisole hydrochloride. For each kilogram of chicken body weight, use 25 milligrams of diet or add drinking water to allow the chicken to eat or drink freely. (2) flooding Ling (piperazine citrate). 0.2-0.25 grams per kilogram of chicken weight is fed or feed directly.
