After the autumn, the weather turns cold, the old laying hens enter the late stage of laying eggs, and the new laying hens continue to lay eggs. The following feeding management methods can make the chickens produce more eggs and improve economic benefits.

1. Adjust the chickens: eliminate chickens with less eggs, stop chickens, weak chickens, chickens, chickens with severe stagnation, chickens with short peaks, over-fat or lean chickens, and diseases without treatment. chicken.

2, increase feed nutrition: After a long period of laying and hot summer, the old laying hens are already very tired, after the autumn should feed more animal protein feed, add a variety of vitamins in the feed, so that the laying hens will resume production as soon as possible egg. New laying hens in spring must also supply more nutritious feed to increase egg production.

3. Increasing the illumination time: After the autumn, the natural daylighting time is gradually shortened, and the laying hen should be moderately supplemented with light during the laying period. When supplementing the light, the ground light intensity is preferably 3 lux. Turn on the lights twice a day, turn on the lights until dawn at 4-5 in the first morning, and turn on the lights until 20-21 in the dark.

4. Forced moulting: Forced moulting can promote the simultaneous moulting of laying hens and start production at the same time. Manual forced moulting can be done by adding 2.5% zinc oxide or 4% zinc sulfate to the diet of the laying hen. During high-zinc diets, water is not stopped and the light can be reduced to 6-8 hours per day. After 7-8 days, the chicken weight decreased by about 25% (such as less than 25% weight loss, continue to feed high-zinc diet), and stopped production. At this time, the feed was changed to the pre-feed, and the first day of each chicken was fed 30-40. Gram, then increase 10 grams per day, increase to 100 grams per day to allow the laying hens to eat freely. Gradually increase the light time to 16 hours per day when returning to normal feeding.

5, timely deworming: autumn is the best time for laying hens, the following drugs can be used for deworming: (1) levamisole hydrochloride. Use 25 mg of mixed feed per kg of chicken weight or add to the drinking water to allow the chicken to eat or drink freely. (2) sputum sputum (piperazine citrate). Use 0.2-0.25 grams per kilogram of chicken body weight, feed the feed or feed directly.
