A fear of startled chicken ducks, mildly surprised, the egg production rate decreased by 5%, severely frightened, the egg production rate can be reduced by more than 30%, and produce soft shell eggs for several days. Therefore, when feeding ducks and ducks to try to prevent them from being frightened, wild grazing do not rush to rush and squeak loudly, but also pay attention not to breed new and old ducks together, so as not to affect the new duck ducks lay eggs.
Two afraid of hot duck duck sweat glands, high temperature is very unfavorable. In the evening, when the temperature exceeds 37°C, the ducks should be allowed to leave the house to let it cool off during the night and do not grazing at high temperatures during the day.
Third, fear of poisonous wild grazing, to prevent ducks from entering the field or ditch sprayed with pesticides.
Fourth, the fear of disease is the enemy of ducks and ducks. In case of duck plague or duck cholera, duck plague vaccine and duck cholera vaccine must be promptly injected.
Fifth, the oldest laying ducks have the highest egg production in the first year and will decline year after year. The average laying season is 2-3 years.
Fearless and healthy ducks are especially strong in spousehood. If the proportion of ducks and ducks in the duck group is not appropriate, it will seriously affect the laying rate of laying ducks. The ratio of male to female ducks in the duck group should be 1:25.
Seven are afraid of no-night-eaten ducks, which have a good metabolic function and will feel hungry at night, so they must supply water at night.
8 Fear of feeding a single duck to feed the full price of feed, if the nutrients in the feed are not balanced, it will not only cause the duck to consume more food, but also has a low egg production rate and the benefit is poor. Nutritional level in duck and duck diets: 2700 kcal metabolic energy, 16%-17% crude protein, 4%-5% crude fiber, 2.5%-3% calcium, and 0.5%-1% phosphorus per kilogram of feed. Salt 0.3% - 0.5%, but also trace vitamins and feed additives. Feed formulation: 50%-60% of rice-based concentrate feeds, 10%-15% of protein feeds based on fishmeal and soybeans, and accounted for cake-based feed consisting of rapeseed cakes, cottonseed cakes, or glutinous cakes. 11%-20%. In addition, every 100 kg of feed should be added shell powder or bone meal 2 kg, 3 grams of salt, a variety of vitamins 20 grams, a variety of feed with a good mix, processing and smash. When used, mix thoroughly and feed.
