Seize the key points of feed quality control
Grasping the key point of feed quality control
The improvement of formula technology is easy to see the effect, and the cost reduction is immediate. Long-term efforts are required in the procurement of raw materials, quality control of raw materials and feed processing. All along, in our habit thinking, when it comes to feed quality, the first thing that comes to mind is the feed formula. It is believed that the management of feed quality is concentrated on the feed formula. This kind of thinking has a big misunderstanding, and it is easy to appear on the feed quality control work and processing. Process flow management is not enough attention. The quality control of feed is a systematic project. The quality and cost of feed products depend directly on the quality of raw materials, feed formulation and processing technology. The quality of raw materials is the basis of feed quality. The design of feed formula is the core of feed quality, and the processing technology is the guarantee of feed quality. Therefore, while improving the level of formula technology, in order to improve the quality of feed, it is also necessary to strengthen the quality control of raw materials and improve the level of processing technology.
1 Strengthen the quality control of raw materials
The quality of raw materials is the source of product quality. The quality of feed products mainly depends on the quality of raw materials used in production. Strict control of raw material quality is the basis of quality assurance system for feed products. Production statistics show that 40% to 70% of the difference in nutrient content and quality of feed products comes from the difference in raw material quality. If the quality of raw materials is not effectively controlled, the products produced are not guaranteed. Feed ingredients are the most important control point for the production of safe feed. The unsafe factors of feed products mainly come from three aspects: First, the chemical pollutants present in industrial waste, air, soil and water sources are bioaccumulated or excessive. The application of chemical fertilizers and pesticides eventually contaminates the feed ingredients, causing heavy metals, nitro and aromatic hydrocarbons, pesticides, fertilizers, etc. to exceed the standard; secondly, the damage caused by human factors, mainly to achieve a certain purpose (such as promoting the growth of cultured organisms) Or prevent diseases), artificially add certain toxic and harmful drugs to the feed, abuse of heavy metals, copper, zinc, selenium, etc. caused by drug feed additives, or drug residues; again, during feed processing (receiving and storing raw materials) Materials such as cleaning, crushing, mixing, granulating, cooling, crushing, grading, packing, and finished product storage are contaminated by Salmonella, Escherichia coli, Botox, and mycotoxins. The price of raw materials directly affects the cost of the formula. It must be combined with local feeding experience and local natural conditions to make full use of local feed resources and design a more reasonable feed formula. This can ensure sufficient source of feed ingredients, reduce their transportation costs, reduce the production cost of feed, and improve the economic and practicality of feed products. At present, companies pay more attention to the procurement work, do a lot of work, and play a very good role in reducing feed costs. However, there is still a phenomenon of heavy price and light quality, and heavy supply of light goods. The quality of the raw materials purchased by the purchasers is numerous, and the reliance on the determination of the laboratory is unreliable. This is not conducive to the quality control of raw materials. risks of.
2 Improve the level of processing technology
Feed processing is closely related to animal nutrition. High-quality feed products need to be realized by scientific formula design and scientific processing and manufacturing. Years ago, feed mills were just a place to mix cereals into powders; today, with new enzymes, antibody-promoting additives, and new processing technologies, feed mills will become an integral part of the feed formulation process. What managers need to care about is the entire process.
2.1 Feed crushing particle size control
Crushing is one of the most energy-intensive sections in feed processing, and it is also a prerequisite for subsequent processing in other sections. The size of the pulverized particle directly affects the digestion and absorption of the animal, the cost of pulverization, the subsequent processing steps and product quality. Controlling the crushing size of the material is a key part of feed production. According to the production of different varieties of feed, the sieves should be replaced in time to adjust the fineness of the materials.
2.2 Control of batching accuracy
Accurate ingredients are the premise and guarantee for the strict implementation of production formulas, especially the trace components that have a direct impact on feed safety. The accurate measurement of pharmaceutical additives is very important. Once errors occur and are not discovered in time, they cannot be remedied in the follow-up section. Will bring serious pollution. Minimize the amount of manual addition as much as possible, using a combined weighing system, "large scale with large material", "small scale with small material".
2.3 Control the mixing uniformity
The mixing process is the core of the feed processing process and the most problematic place in quality control. Whether the finished feed is uniform or not is the key to the quality of the feed product, directly affecting whether the animal can obtain sufficient and comprehensive nutrients from the feed. If the uniformity of the feed is not good, the animal will have some excess nutrients and other nutrients. Especially for some trace components, if the mixing is not uniform, the above substances will be excessive in the local part of the product, resulting in the content of some feed drugs in the medicated feed exceeding the standard, causing certain pollution. In order to ensure the uniformity of the finished feed, it is first necessary to thoroughly mix all the components in the mixing process, and secondly take effective measures to ensure the accuracy of the mixing amount of each component in the feed.
2.4 and granulating control technology
The quality of pelleted feed is reflected in the quality of its sensory quality. In the production of granular materials, the processes of quenching, granulating, cooling, sieving, etc. shall be adjusted and monitored at any time to ensure the smoothness of the surface of the granular materials, to ensure the uniformity of their size and length, and to ensure the powdering rate of the feed, including The powder rate, water resistance and moisture content should meet the relevant national regulations. Only in this way can we produce qualified products and ultimately be accepted by customers.
Each company should formulate corresponding process parameters according to the specific conditions of its own equipment and the requirements of production, and control the production of feed. The work of feed quality is a systematic project, which requires understanding and cooperation from many internal departments. It also requires each company to mention the quality of feed to a relatively high position. Everyone can work together to make the quality of the feed.
