The following points can be achieved by selecting compound feeds to obtain high-quality compound feeds:
(1) From the sensory point of view, the color is uniform, the surface is smooth, there is no moldy deterioration, no greasy, no agglomeration and odor. It is a new system for the year.
(2) Conditionally analyze several major nutritional indicators, such as crude protein, crude fat, water, and ash, to determine whether they meet the criteria.
(3) To understand whether the formula used by the sales company is an appraisal passed by a scientific research unit, or whether the product is qualified or qualified in the appraisal or inspection.
(4) Select 2-3 kinds of high-quality bait each year for feeding comparison and choose the best one from among them.
From the production to the sales of the compound feed, from the purchase to the feeding, in the course of storage, such as negligence or improper measures, it will upset the quality of the disappointment, affect the feeding effect, resulting in direct or indirect economic losses. For this reason, we must attach great importance to the storage and management of compound feeds.
Due to moisture, temperature, humidity, insect pests, rodents, and microorganisms, the compound feed is damaged during storage. Therefore, appropriate measures must be taken to avoid its harm.
(1) Moisture and humidity: The water content of compound feed is generally required to be below 12%. If the water content is controlled below 10%, ie, the water activity is not more than 0.6, no microorganisms can grow, and the water content of compound feed is greater than 12%. Or the humidity in the air is large, the compound feed will return to the tide, easy to mold at room temperature. Therefore, the compound feed must be kept dry during storage. The packaging should use double bags, airtight plastic bags and external textile bags. Storage warehouses should be dry towers, ventilation, ventilation methods are natural ventilation and mechanical ventilation. Natural ventilation is simple and economical, but the ventilation is small. Mechanical ventilation uses a fan to blow the air into the feed bowl. The effect is good, but it consumes energy. The warehouse is piled up and the ground is covered with moisture-proof materials. Generally, the ground is covered with a layer of clean disinfection. The rice hull, wheat bran or straw, and then laid on the mat or bamboo mat, you can pile up compound feed.
(2) Insect pests and rodent pests: The pests can eat most of the bait ingredients. Due to the excrement of insect pests, body nets and bad taste, the quality of the bait is reduced. The main factor affecting the growth of most pests is temperature, Relative humidity and bait moisture content. The appropriate growth temperature for these insect pests is 26-27°C, and the relative humidity is 10-50%. Below 17°C, the reproduction is affected. In general, moths eat the surface of the bait, while the beetle eats the whole bait. At the appropriate temperature, the pests multiply, consume feed and oxygen, produce carbon dioxide and water, and release heat at a temperature of 45°C in the concentrated area of ​​the pest. The generated water vapor agglutinates the surface layer of the bait, causing the bait to agglomerate and cause mildew, resulting in serious deterioration of the formulated bait, which may also lead to spontaneous combustion due to high temperatures. Rat rodents eat feed, destroy the warehouse, infectious bacteria, pollute the feed, is a relatively serious group of animals. In order to avoid pests and rodents, before the storage of feed, the walls of the warehouse should be completely removed, cracks and dead ends should be blocked, and the corner holes should be blocked. Sealed fumigation should be performed to reduce pests and rodents.
(3) Temperature: Temperature has a great influence on stored feed. When the temperature is lower than 10°C, the growth of mold is slow. If the temperature is higher than 30°C, it will grow rapidly and the feed quality will deteriorate rapidly. The manual laborers in the feed are now highly unsaturated. Fatty acids are also susceptible to oxidative deterioration when the temperature is high and humidity is high. Therefore, formulated feed should be stored in a low-temperature and ventilated place. Treasury should have thermal performance to prevent the penetration of sunlight, radiant heat, and the top of the warehouse should be brushed with a heat insulation layer; walls painted white to reduce heat absorption; trees can be shaded around the warehouse to avoid sunlight and shorten the sun time.
Different types of feed, its storage time, the requirements are not the same.
The full-price pellet feed, which is made by steam quenching or water squeezing, can kill most of the microorganisms and pests, and has a large gap and low water content. The gelatinized starch encloses vitamins, so its storage performance is good as long as it is moisture-proof. Ventilation, dark storage, no mildew in the short term, less damage to vitamins.
The full-price powdered feed has a large surface area, a small porosity, poor thermal conductivity, and is easy to return to moisture. Fats and vitamins are exposed to air and are easily oxidized and damaged by light. Therefore, such feeds should not be stored for a long time.
Concentrated feeds are rich in protein, contain trace elements and vitamins. They have poor thermal conductivity, are prone to hygroscopicity, and microorganisms and pests are prone to growth. Vitamins are also easily destroyed by light, heat, oxygen and other factors. Anti-fungus agents and antioxidants should be added to the concentrate to increase storage stability. General storage 3-4 weeks, to be sold or used in a timely manner.
Additives generally require storage in low humidity, dry, dark places. The packaging should be sealed; many mineral salts can promote the decomposition of vitamins, so mineral additives should not be stored together with vitamins; additives, premixes to avoid oxidation to reduce the potency, should be added antioxidants, such as BHT, ethoxyquin, etc.; Storage Time has a direct impact on the potency of additives. The loss of certain vitamin additives is 5-10% per month. Its products should be fast-growing, fast-selling and fast-acting. Various additives are best used in a short period of time. Avoid long-term storage, not to purchase this year, only to use it next year.
