An active substance is the main active ingredient in a drug. Take a simple aspirin for example. Acetyl salicylic acid is synthesized through chemical process and purified to a specified purity. The synthesis of acetyl salicylic acid is made by adding various excipients, such as fillers, adhesives, disintegrating agents, etc., and then pressing it into tablets. The production of apis is generally either pure chemical synthesis, biological fermentation, or semi-synthesis, with biological fermentation followed by extraction followed by synthesis. Not all pharmaceutical enterprises make API by themselves, and many manufacturers do not have the scale to produce API. Even if there is large-scale production, the cost of production may be much higher than that of procurement. Therefore, most manufacturers buy bulk drugs, and then make preparations, so that the production of drugs can be completed without a very large scale. At present, China and India have become the two largest API producers in the world. Many European and American pharmaceutical companies, even some of their own original drugs, will give up the production of API as the patent expires and the market matures, and turn to purchase apis from China and India,API production generally go through laboratory, generated through laboratory bottle container canister, taking after successful, pilot magnification, which is to enlarge the quantity of the production, then no problem tends to be faced with a lot of small scale experiment, a very simple example, the heating process, due to the relatively small amount in the laboratory, uneven heating cases is less, But if it is scaled up to a few tons of pot, at this time the heating may be not hot in this place, where the paste pot, at this time you need to stir, but the speed of mixing is appropriate, this process needs to calculate or grope. Finally from the pilot test, and then to the formal production, the volume of further amplification, and will face a lot of new problems. Therefore, although some drugs are generic, the research and development of the whole process from small test, pilot test to the final mass production is indispensable, so even generic drugs have very high research and development costs. api meaning,api products to buy,best api products,cheap api products,best buy products api,best api products Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropic.com
Feeding pigs with powder residue should pay attention
Feeding pigs with powdered slag can be a cost-effective way to reduce the use of concentrates and lower feeding expenses. However, it's important to take certain precautions when incorporating this material into pig diets.
For growing and finishing pigs, powdered slag can be included in larger amounts, but it should generally not exceed 50% of the total diet. Fresh slag has a high moisture content—over 80%—which means it contains very little dry matter. To avoid digestive issues like diarrhea, it's advisable to mix in some hay powder, sweet potato powder, or other fibrous materials to improve palatability and digestion. Since the main component of slag is carbohydrates, it’s ideal for promoting fat deposition, making it suitable for fattening pigs and boars when used in moderation.
However, for young pigs, breeding boars, and pregnant sows, the amount of slag should be limited to less than 20% of their diet. This is because slag is high in carbohydrates but low in protein (around 2%), and it lacks essential amino acids such as lysine, methionine, and tryptophan. Additionally, many of the vitamins and minerals found in sweet potatoes are lost during processing. Feeding too much slag to growing pigs can hinder their growth, while overfeeding boars may reduce sperm quality, and feeding too much to pregnant sows can lead to stillbirths or malformed piglets. It may also cause postpartum milk deficiency.
To ensure balanced nutrition, it's crucial to supplement the diet with protein sources like fishmeal, soybean meal, blood meal, and mineral supplements such as bone meal, shell powder, and limestone. Adding Vitamin-rich ingredients like carrots can also help compensate for nutrient deficiencies. By combining these elements, you can enhance the overall nutritional value of the feed and improve the economic efficiency of your pig farming operation.
