duck
Strengthen ventilation: ensure the air circulation of the duck house, such as nighttime hot weather, the ducks cry uneasy, you can drive the ducks into the pool water, you can also use artificial fans and other artificial ventilation.
With good feed: Miao duck raised to 7 days old can be transferred to normal feeding. Feed mix: corn 58%, bran 10%, bean cake 25%, fishmeal 3%, shell powder 2%, bone meal 1.5%, salt 0.5%, per kilogram of feed containing metabolic energy 11.72 ~ 12.14 MJ, crude protein 18% ~ 19%. Ducks feed once every 3 hours after 7 days of age, and feed 3 to 4 times daily after 20 days of age, and can use paddy fields for grazing to reduce the amount of materials used.
Strengthen the insulation: from the end of October we must do a good job of cold insulation work to prevent cold wind invasion, grazing ducks should be rushed to the warm sand, pond ditch, drains and other shelter, so as not to suffer cold and cold.
Strengthen the epidemic prevention: Regularly check the temperature in the house to observe the diet, defecation and activities of the ducklings, and usually add the compound of diarrhea net, oxytetracycline, vitamins, calcium and other drugs to the feed to prevent the occurrence of the disease. Once the duck has developed, it should be treated immediately and the sick duck should be kept in isolation.
chicken
In the early fall season, it is the spring of raising the hen's initial stage of production. The replacement hens should be fed with transition materials in time. In general, 20-week-old chickens are fed pre-egg feed, also called transitional feeds, with 1% calcium and 16.5% crude protein. Use 15 days to gradually complete the reloading process and avoid excessive rush to prevent diarrhea. When the egg production rate reaches 5%, the calcium in the feed should be 3.4% to 3.5%, and the crude protein should reach 18%.
Reserve hens generally enter sexual maturity at 15 weeks of age, during which period the natural light is gradually reduced. Due to the short illumination time and the long time to reach sexual maturity, supplemental illumination should be started after 15 weeks of age to meet the needs of sexual maturity. In general, the light time after 15 weeks of age should be maintained at the light hours of 15 weeks of age, but the light can not be too strong to prevent the emergence of chicken feathers, toes, backs and other evils.
The initial illumination time of laying hens is 13-17 hours. While refueling and calcium supplementation, the uniformity of population development should be grasped. Large, medium, and small hens should be reared in groups and transferred regularly. Avoid sudden increase in material or sharp reduction in material, the effectiveness of which can be shown after the 21st, should not be rushed. The weight of light-weight chickens should not exceed the size of medium-large chickens, so as to avoid affecting sexual maturity due to fat deposition.
At the same time, to provide enough clean drinking water, 2 to 3 times a week can also supply light salt water, in order to improve the hen's constitution, increase feed intake. And control the hen's initial body condition.
For hens that have passed one egg-laying year, the management of the moulting period must be carried out so as to speed up the recovery of production.
