Misuse of Premix and Countermeasures

In recent years, the popularization and application of premixes has become increasingly widespread, which has played a good role in promoting the development of the aquaculture industry and the raising of the raising level. The majority of farmers have accumulated rich experience in the selection of premixes and scientific feeds, but there are still some misunderstandings in the actual use of premixes, so as to fail to realize all the advantages of premixes to achieve the ideal Feeding effect. We will now summarize some of the issues related to the selection and use of premixes that are often encountered in feed operations, for reference by farmers.
1. Choose a brand There are many kinds of pre-mixes on the market and the quality is uneven. Xuzhou Feed Supervision Station conducted tests on 25 brands and 56 varieties on the Xuzhou market, a considerable number of which were unqualified. According to the national requirements for the supervision and management of feed product quality, any product that meets the quality requirements must have a product label. The label includes the product name, feed object, approval number, nutrient content, usage, dosage, net weight, and production. Date, factory name, site; Second, product specification; Third, product certification; Fourth, there is a registered trademark. Only by mastering these basic knowledge can you purchase qualified products.

2. Select the quality of pre-mixed material. Over-emphasis on the quality of product packaging is a comprehensive reflection of the intrinsic quality and external quality of the product. The intrinsic quality of the product refers to the nutritional index of the product, the reliability of the product, the economy, etc. The external quality of the product refers to the appearance, color, and smell of the product. Some farmers tend to focus on the appearance of the feed and how it is packaged when selecting feed products, followed by color, smell and taste. Due to the fierce competition in the feed market, some businesses have tried their best to make efforts in packaging and product color, taste, and fragrance. However, the internal quality of the product has not been improved. Farmers do not understand and are often fooled. Should choose some good reputation, moderate prices, especially after the feeding of the regular manufacturers.

3, in the choice of compound feed can not be too fathoming cheap saying: "a price, a delivery" is a certain truth. Good product quality feed, because of genuine, often high prices, low prices of products are often low quality, when you choose, you can not just see how much a bag of feed, but to see its nutritional value, according to the formula to calculate the price of feed, If necessary, test feeding can be done. Long-term feeding of premixes with insufficient nutrient content will lead to diarrhea and diarrhea in livestock and poultry. This will not only hinder the growth of livestock and poultry, but also increase the cost of farming.

4, can not arbitrarily change the recommended formula all types of premixes have their own estimated formula, these formulas are generally scientific and reasonable, can not be arbitrarily changed, such as: soybean meal into rapeseed meal or cotton aphid, corn replaced Wheat, also can not increase or reduce the amount of soybean meal, resulting in high or insufficient protein content, affecting growth and development, reducing economic benefits.

5, poor uniformity of mixing Most farmers in rural areas are using artificial mixing when preparing feed. Artificial mixing, the degree of uniformity can not meet the requirements, seriously limiting the use of premixed materials. The coefficient of variation of the feed mixing uniformity is usually not greater than 10%. Conditioners should purchase a blender, dilute the premix before mixing, and mix the feed and premix before mixing.

6, the use of methods, methods of defect mainly in the following areas:

(1) Do not feed according to the manufacturer's instructions for use, and some use the premix as “MSG”. Add 1-2 randomly in the feed and stir it. This feeding is not scientific. Nutrition is not comprehensive, should be formulated in strict accordance with the recommended formula;

(2) Some feed chickens with chicken feed. The first limiting amino acid in chickens is methionine, and the first limiting amino acid in pigs is lysine. Therefore, pigs still lack lysine and methionine is excessive in chicken feed. The composition of trace elements and vitamins in premixes of chickens and premixes of pigs is also different, and they cannot be replaced by each other.

(3) Feeding too much at one time causes the chicken to eat pellets first, leaving the powder remaining, resulting in inconsistent nutrient intake and waste of feed. The second feed should be done after the first feed is eaten.

7. The crushed particle size is not suitable for proper feed particle size, which not only ensures the feed intake of livestock and poultry individuals but also the same level of nutrient intake, and can prevent the occurrence of metabolic diseases and increase feed remuneration. However, in the work, it is often found that some farmers tend to reduce the proportion of powder, in order to save, and often crush the particle size too large, making chickens difficult to eat, affecting normal growth and development, conventional granular chickens below 1 mm, medium chicken 1-2 Millimeters, 2 to 2.5 mm chicken is appropriate.

8, storage time is too long

(1) The shelf life of the premix in the summer is generally about 3 months. It takes a period of time before delivery by the factory, the dealers, and the farmers. Some farmers will not be able to buy home for a while, and they will be stored for several months. Expired, this will inevitably lead to imbalance of nutrient composition, quality decline, serious moldy, can not feed, farmers must be able to see, after the shelf life to buy, store, so as to avoid economic losses;

(2) In order to save labor, farmers need to process large amounts of feed at one time. This is very easy to mold, which not only destroys the nutrient components, but also makes the animals susceptible to Aspergillosis or Aspergillus flavus poisoning and increases the cost of breeding. In principle, it is better to use current feeds. The prepared feed should not be used for more than one week, and should be stored in a cool and dry place.

Hyaluronic Acid For Skin, Sodium Hyaluronate is well known as the best [Natural Moisturizing Factor". For  Hyaluronic Acid Cream . In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by international cosmetics industry. With its unique film-forming and hydrating characteristics, Hyaluronic Acid Powder Cosmetic Grade is used as a highly effective humectants in cosmetics. It attracts moisture to the skin and hold moisture in the skin, which preserve skin smoothness, suppleness and elasticity. 1 gram of Hyaluronic Acid Powder Cosmetic Grade is able to retain up to 1000 gram of water. So it is regarded as the [key to the fountain of youth".

The effects are as follows:

(1) Moisturizing effect 
Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell in skin surface and make the corneum hydration and softening. Compared with other humectants, Sodium Hyaluronate is less effected by the environment as it has the highest hygroscopic capacity in a relatively low humidity (e.g., in a dry winter), but has the lowest hygroscopic capacity in a relatively high humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate makes the skin adapt to different seasons.
(2) Skin nutrition effect
Sodium Hyaluronate is the inherent biological materials of skin. The exogenous Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can penetrate into dermis directly to improve the nutrient supply.
(3) Skin repair effect
There is some evidence that topically applied Sodium Hyaluronate can reduce skin irritation from various causes. During clinical trials it was also shown that this ingredient is effective in promoting healing and fighting inflammatory conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger and antioxidant, helping to protect the skin from the aging effects of excessive sunlight exposure.
(4) Emollient and Film-forming
Sodium Hyaluronate is high polymer with high lubrication and film-forming. Sodium Hyaluronate contained in cosmetics creates protective film on the surface of skin, which retains moisture, and at the same time prevents moisture in the skin from evaporation, so that improves freshness of the skin.  
(5) Thickening
Sodium Hyaluronate solution have high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to improve the thickening and stability.
