First, the advantages of self-mixed feed
1. Can make full use of local resources and reduce feed costs
When self-produced feeds are prepared, they can be used locally, locally, and locally, to make full use of self-produced feeds or feeds with high local nutrient content, cheap prices, and guaranteed sources, to minimize freight and labor costs and reduce feed costs. In particular, in some areas where farming is a main industry and aquaculture is a sideline, it is also possible to make full use of winter time and winter resorts to grow some raw materials such as wheat and rapeseed to supplement the shortage of raw materials for the following year. Lower feed costs.
2. Can add disease prevention drugs in time to control the occurrence of fish diseases
Due to the fact that most of the current farmed fish's full-priced feed is hard granular, there are quite a few inconveniences in adding additives or disease-preventing drugs. When self-proportioned feed is used, various feed additives and disease-preventing drugs can be timely added according to the needs of farmed fish to further improve feed quality, increase feed conversion rate, and strengthen the prevention and treatment of fish diseases.
3. It is helpful to design suitable feed formula according to stocking mode
Different regions have different stocking patterns for different farmers, and the required feed nutrient levels are also very different. Most of the full price feeds produced by most manufacturers are based on the nutrient requirements of the main fishes. Considering the nutritional needs of fish stocks and using self-contained feeds, the appropriate feed formula can be designed based on the farming pattern and the stocking status of different fish species, taking into consideration the stocking ratio and nutritional requirements of the main fish and the matched fish. To meet the nutritional needs of fish cultured.
4. Facilitate timely adjustment of feed formulation based on fish growth
With the growth of farmed fish, the demand for nutrients is also changing. Therefore, the nutritional level of feed is also required to be adjusted. Only in this way can we meet the nutritional needs of fish at all stages of growth and it can be effective. Reduce feed costs. If the feed is fed with full-priced feed, it will be more passive. It will not be able to timely adjust the formula according to the growth of the fish. When preparing its own feed, it will be able to timely adjust the formula according to the growth of the fish, properly reduce the nutritional level, and reduce unnecessary waste.
5. Special granulation conditions are conducive to the addition of various enzyme preparations
Enzyme preparations have been used for many years in livestock and poultry feeds. Since various fish feeds undergo a process of conditioning and maturing during processing, enzymes act as a type of active protein, and their activity is easily destroyed during this process. Thus limiting its use in fish feed. The self-made feeds mostly use small feed granulation machinery, and the lack of conditioning and maturing processes during the processing, and the granulation process does not have the conditions of high temperature and high heat, which not only avoids the loss of some heat-labile nutrients in the feed, but also gives each The addition of heat-labile enzyme additives, such as heat-labile feed additives, offers the possibility. Enzyme preparations can, to some extent, improve the utilization of feed, reduce the feed coefficient, reduce environmental pollution, and help promote the growth of farmed fish.
6. Shorten the storage time of feed and help to ensure the quality of feed
Self-formulated feeds are generally provided with the use, and the storage time of the feeds is short. This avoids the loss of various nutrients and the deterioration of the feed during prolonged storage and long-distance transportation, thus ensuring the quality of the feed.
Second, the difference between self-made feed and full-priced feed
1. Raw materials
At present, in some areas where self-made feeds are used, various raw materials are mostly purchased by premixed material distributors. These dealers lack knowledge about raw materials and do not have some necessary testing equipment. Therefore, the quality control of raw materials is often Did not do well. Most manufacturers who produce full-priced feeds have separate laboratories, which can not only control the raw materials well, but also control the manufactured products to a certain extent, ensuring the quality of the feed and stability.
2. Formulation
The design of the feed formula is a relatively technically demanding task, and it is by no means a matter of mixing and mixing several types of raw materials at will. Therefore, it is required that the manufacturers who provide the premixed materials have a professional formulator and can The different farmers need to design a reasonable formula. However, due to the relatively late start of the culture of fish-breeding ingredients, our country is relatively short of technical personnel in the area of ​​aquafeed formulation. Many manufacturers of premixes do not have professional formulators and can only touch stones to cross the river. In addition, some farmers do not trust the technicians, they often adjust the formula without permission, and they are free to increase the amount of raw materials used in limited quantities. Full-price feed mills not only have specialized formulators, but also have strict controls on formula management, and there are no arbitrary adjustments, thus ensuring the scientificity, rationality and seriousness of formulas.
3. Processing
Self-contained feed has a natural insufficiency that the equipment is relatively simple and does not have the superior production conditions of the feed mill, so there are some deficiencies in the feed processing. First, cultivators who use self-proportioned feeds are seldom equipped with crushers and mixers. The fineness and mixing uniformity of raw materials are not as good as those of feed mills. Secondly, self-produced feeds are all made with small granulators, with no steam adjustment. In the quality system, the feed produced has not undergone the process of conditioning, maturing, etc. Some microorganisms in the raw materials have not been inactivated, and feeding may affect the health of farmed fish.
Third, the problems that should pay attention when making self-mixing
1. Pay attention to the raw materials
High-quality raw materials are prerequisites for the preparation of high-quality feeds. Therefore, when self-produced feeds are used, it is imperative to shut down the raw materials, and it must not be excessively cost-effective. As the saying goes, "a price for a product," which is a certain truth, the good quality of raw materials, because of genuine, often high prices, low prices of raw materials are often poor quality. When choosing, you can't just look at how much money you need for a bag of raw materials, but also look at its nutritional value, calculate the price of the formulated feed according to the recommended formula, and if necessary, do a feeding test.
2. Pay attention to the stability of formula and feed
All kinds of premixes are accompanied with recommended formulas. These formulas are generally designed according to common farming patterns, are scientific and reasonable, and cannot be arbitrarily changed during the ingredient process. For example, the amount of soybean meal cannot be arbitrarily increased or decreased, and can not be replaced by rapeseed meal or cottonseed meal at random. Otherwise, the protein content will be too high or insufficient, and the content of antinutritional factors in the feed will be high, which will affect the growth and development of the fish and reduce it. Economic benefits. If the recommended formula is not suitable for your own farming mode, you must make appropriate adjustments under the guidance of the manufacturer's technician. In addition, raw materials of different manufacturers, especially premixes, must not be used at will, because the nutrient content of different manufacturers' raw materials is different. If they are arbitrarily adjusted, the nutritional composition and palatability of feeds will also change. Finally, it will also affect the growth and development of fish.
3 pay attention to the uniformity of mixing
At present, most farmers in rural areas use artificial agitation when formulating feeds. Artificial mixing, the uniformity can not meet the requirements, seriously affecting the use of premixed materials. The coefficient of variation of the feed-mix uniformity is usually not greater than 10%. In order to mix raw materials such as various premixes with small amounts of raw materials, such as soybean meal and rapeseed meal, it is better to adopt a step-wise dilution method, that is, first add premixes, etc., to a small amount of common raw materials for mixing. Repeatedly, gradually dilute until uniform. The best conditions to buy a mixer, before mixing the premix must be properly diluted, feed and premix can be used after mixing.
4. The science of self storage management
Self-provided feed should follow the principle of accompanying use, because the mixed feed is not easy to be stored for a long time, and it should not be over-stocked at one time. Under normal circumstances, 3 days to 5 days with a time, too long will make certain nutrients loss; store to set up a special warehouse, indoor ventilation and light drying, avoid moisture, prevent moldy deterioration, reduce feed digestibility; To prevent contamination, the storage location and packaging feed utensils must be clean and non-toxic, and it is imperative that rats not be stung by random or stored together with pesticides, fertilizers, etc.
