The optimum temperature for cold and warm duckling eggs is 13°C～30°C, and the lowest temperature should not be lower than 6°C. Therefore, the duck house must plug the wind tunnel and close the doors and windows. When the temperature is low, add grass curtains to the windows and doors, spread some wheat straw or straw on the ground, and thicken the surrounding area. Add ducklings every day to add new grass, and increase the stocking density. Feed 8 to 9 eggs per square meter.
Adjusting the diet Winter ducks have high energy requirements. Therefore, it is necessary to appropriately increase the proportion of corn and other energy feeds. Protein content should be reduced, and attention should be paid to feeding green materials such as cabbage and radish.
Imported Premium Fire Retardant
Flame retardants, functional auxiliaries endowed with inflammable polymer flammability, mainly designed for flame retardancy of polymer materials; There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to their usage.
The additive type flame retardant is added to the polymer by mechanical mixing method to make the polymer flame retardant. At present, the additive type flame retardant mainly includes organic flame retardant and inorganic flame retardant, halogenated flame retardant (organic chloride and organic bromide) and non-halogenated flame retardant. Organics are some flame retardants represented by bromine, phosphorus and nitrogen systems, nitrogen systems, red phosphorus and compounds, while inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide and silicon systems.
