A look at the cockroach feeding goose is too fat, egg production is low, and some even stop production; female goose is too thin, lack of nutrition, egg production is also low. For over-fat goose, the fine material should be properly reduced, if necessary, feed concentrates should be suspended, the breeding goslings should be appropriately increased in exercise or grazing, and the thin goose should be fed with fine material to increase the protein content in the feed and should be fed at night. Times. Second, the fecal feed manure feces thick, loose strips, the surface is shiny, with a foot dial can be divided into several segments, indicating that the appropriate nutrition, normal digestion. If the goose's droppings are small, firm and dark in color, the light-digging feces will be granular, indicating that the amount of fine material is too much, the amount of green feed is small, and the digestion and absorption are not normal. The amount of fine material should be reduced and the amount of green feed should be increased. The color of goose droppings is shallow and unformed, and it will spread out as soon as it is discharged, indicating that the amount of concentrated feed is insufficient and concentrate feed should be supplemented. Third, look at the egg feeding geese intake of nutrients is insufficient, the eggshell will become thin, the eggs are small or deformed. If this happens, you must add protein-rich feed such as bean cakes, peanut cakes, and fishmeal to increase the crude protein content of the diet to more than 22%, and increase the amount of feed per goose to 280-320 grams per day, while adding Mineral feed. API Powder is fully defined in ICH Q7A as any substance or mixture of substances intended for use in the manufacture of pharmaceutical products and, when used in pharmaceutical products, as an active ingredient of pharmaceutical products. Such substances have pharmacological activities or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function or structure of the body. The active ingredient of a medicine. Only when an API is processed into a pharmaceutical preparation can it become a medicine for clinical application. alprazolam api powder,pregabalin api powder,buy api powder,api ingredients Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropic.com
According to its source, apis are divided into chemical synthetic drugs and natural chemical drugs.
Chemical synthetic drugs can be divided into inorganic synthetic drugs and organic synthetic drugs. Inorganic synthetic drugs are inorganic compounds (very few are elements), such as aluminum hydroxide and magnesium trisilicate for the treatment of gastric and duodenal ulcer, etc. Organic synthetic drugs are mainly made of basic organic chemical raw materials, through a series of organic chemical reactions and drugs (such as aspirin, chloramphenicol, caffeine, etc.).
Natural chemical drugs can also be divided into biochemical drugs and phytochemical drugs according to their sources. Antibiotics are generally produced by microbial fermentation and belong to the category of biochemistry. In recent years, a variety of semi-synthetic antibiotics are the combination of biosynthesis and chemical synthesis products. Among apis, organic synthetic drugs account for the largest proportion of variety, yield and output value, which is the main pillar of chemical pharmaceutical industry. The quality of the API determines the quality of the preparation, so its quality standards are very strict. All countries in the world have formulated strict national pharmacopoeia standards and quality control methods for the widely used APIS.
Specific API after processing -- pharmaceutical preparations
The term API is used mainly in relation to the finished product. Mainly raw materials obtained by chemical processing means, supply raw materials for the production of finished drugs. For example, cefpirome sulfate for injection is a drug, then cefpirome sulfate is an API
