Zinc is a trace element necessary for the growth and breeding of livestock and poultry. When zinc deficiency in feed or zinc in the feed is not easily absorbed by livestock and poultry, zinc deficiency occurs in livestock and poultry, leading to body thinning of the livestock and poultry, thickening of the skin, marked shrinkage of the testes of breeder and breeder, reduction of sperm, growth, Breeding is affected. Therefore, livestock and poultry feed must not be deficient in zinc, in some zinc-deficient livestock and poultry feed, zinc should be properly supplemented.
Zinc supplementation of livestock feed is appropriate, and zinc sulfate or zinc carbonate can be used to mix in. The amount of supplementation can vary depending on the species and growth period of livestock and poultry. Generally, the amount of zinc sulfate or zinc carbonate added per kg feed is 50-60 mg of pigs within 20 kg, 20-50 kg of pigs and 40-50 mg of pregnant sows, and 50-100 kg of pigs. 30-50 mg, 40-60 mg for sows, 30 mg for sheep, and 50-100 mg for birds. If livestock and poultry have symptoms of zinc deficiency, the amount can be increased by 0.5-1 times. When zinc sulfate or zinc carbonate is added to livestock and poultry feed, the food intake of calcium and zinc by livestock and poultry must also be adjusted so that the calcium content in the feed can be maintained at 0.65%-0.75%. In order to achieve the purpose of zinc supplementation.
The cell culture flask adopts advanced surface treatment technology, which is suitable for the suspension and adherent growth of cells and tissues. The lid is divided into two types: ordinary sealing lid and hydrophobic filter membrane lid. The membrane lid can effectively prevent pollution while allowing gas exchange. It is for customers to complete Choose from different training goals.
The filter membrane cover of the cell culture bottle is designed to facilitate the exchange of gas inside and outside, effectively prevent pollution, ergonomic design, easy access; short and wide bottleneck, easy to enter and exit the pipette and cell shovel, it is a new type of cell culture treatment surface, It increases the persistence of surface wetting, favoring more uniform cell attachment. Cell culture flasks feature a covalently bonded hydrogel layer that reduces cell adsorption activity and is a special surface coated on culture flasks that mimics the natural cell growth environment and supports the expansion of stem cells.
