At present, many units self-produce feeds in order to reduce feed costs, but due to lack of scientific knowledge, incomplete raw materials, lack of laboratory equipment and other reasons, the feed formulation is unscientific, feed nutrition is not complete, it is difficult to meet the growth needs of pigs, can not fully play its production performance. Therefore, ten points are proposed for the problems and deficiencies of self-formulated feeds: First, the appropriate breeding standards should be selected first. In the self-provisioned feed, it is necessary to first select appropriate feeding standards based on the pig's breed, age, growth and development stage, and production purpose and level. The nutrient needs of the pig and the supply of nutrients to the feed are unified to determine the nutritional requirements to meet the requirements. The nutritional needs of pigs maximize the conversion rate of feed and increase feed remuneration. Second, make full use of local feed species resources. When choosing raw materials, we must adhere to local conditions, draw materials locally, make full use of self-produced feeds or feeds with high local nutrient content, cheap prices, and guaranteed sources, and try our best to save on freight and labor expenses and reduce costs. Third, ensure the quality of feed. It is required to use fresh feed, but it is strictly prohibited to use moldy and degenerative feeds. To control toxic feeds (such as cottonseed cakes), it is necessary to strictly control the amount of feed and do detoxification treatment. Otherwise, even if it meets the standards in theory, it cannot actually guarantee the live pigs. Nutritional needs also affect pig growth and feed utilization. Fourth, pay attention to palatability. Palatability directly affects the feed intake of pigs. Therefore, when formulating feeds, feedstuffs with good palatability should be used more, and those with poor palatability should be used less; feeds with poor odor and poor palatability should be increased from little to large, and gradually increased to give them an adaptation process. Try to make the pigs in a short period of time. Eat inside. In addition, change the feed or ratio slowly, sudden changes will reduce palatability, resulting in indigestion, affecting growth. Fifth, varieties should be diversified. In order to ensure perfect nutrition and high feed digestibility, it is best to use a variety of feeds to match, at least 4 to 5 kinds of fine, coarse, green materials with a reasonable mix to play a complementary role of various feeds, improve feed utilization. Six, with reasonable. When formulating feeds, the proportion of refined roughage should be appropriate, and a well-matched diet should achieve nutritious, moderate volume, and good palatability to ensure that pigs eat enough to eat and satisfy nutritional needs. Otherwise, if the feed volume is too small and the nutrient concentration is large, the pig will not feel full after eating it, and it will not affect its growth. Seven, pay attention to the cellulose content of feed. Pigs are monogastric animals and have poor digestion of crude fiber. Therefore, the amount of cellulose in the feed should be controlled in accordance with the limits of the feeding standards. The piglet should not exceed 4%, the growing pigs and breeding boars should not exceed 6% to 8%, and the breeding sows should not exceed 10% to 12%. Eight, with the uniform. After all kinds of raw materials are weighed according to the proportions, the basic materials such as corn, bran, and cakes are mixed evenly, and then the other materials with less addition amount are mixed evenly, and it is necessary to mix and replenish the ingredients in the mixing process, especially For the various additives used in the diet, it is necessary to adopt a pre-mixed method, that is, first mix with a small amount of auxiliary materials, then mix with more auxiliary materials, and then mix it into the entire diet repeatedly to mix evenly; otherwise, a poisoning accident may occur. Nine, processing modulation should be reasonable. Doing a good job in raw material processing and modulation is the key to improving feed digestibility. Self-made feed is generally a powder feed. In addition to wheat bran and rice bran, raw materials such as corn, cakes, and rice are crushed to a level of 1.5 mm. To be appropriate, bean cakes, cotton cakes, etc. must be boiled to destroy trypsin and gossypol toxins, rapeseed cake to remove erucic acid in order to improve the digestibility of feed. X. Deposit management must be scientific. 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, about 3 days to 5 days, if the time is too long, certain nutrients will be lost. When storing, special warehouses shall be set up, indoor ventilation shall be light and dry, avoid moisture, prevent mould from deteriorating, and 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.
Dehydrated millet onions are made by air-drying fresh millet onions for easy transportation and storage. It is used in family meals, restaurants and seasonings. Delicious and delicious, it is an indispensable spice in life. In life, people don't know how to eat dehydrated millet onions. Here are some practical methods of millet onions. First of all, dehydrated dried onions can stimulate the body's sweat glands and achieve the effect of sweating and heat dissipation. Scallion oil can stimulate the upper respiratory tract, making it easier to cough up sticky phlegm. Onions contain allicin, which has obvious anti-bacterial and viral effects. In particular, the inhibitory effect on Shigella and dermatophytes is more obvious.
