The "ten elements" of self-provisioning pig feed in pig farms

At present, many units prepare their own feed in order to reduce the cost of feed. However, due to insufficient scientific knowledge, incomplete raw materials, and lack of laboratory equipment, the formula of the feed is unscientific. performance. Therefore, in order to address the problems and shortcomings of self-made feed, ten key points are made:

First, we must choose appropriate feeding standards. In self-feeding, we must first select appropriate breeding standards based on pig breed, age, growth and development stages, and production goals and levels, unify the nutritional needs of the pigs and the supply of nutrients to the feed, and determine the nutritional needs to meet The nutritional requirements of pigs maximize the conversion rate of feed and increase feed compensation.

Second, make full use of the resources of local feed varieties. When selecting raw materials, we should adhere to local conditions, take local materials, make full use of self-produced feed or feed with high local nutritional content, cheap prices, and secure sources to minimize shipping and labor costs and reduce costs.

Third, to ensure feed quality. It is required to use fresh feed, and it is strictly forbidden to use moldy feed. Toxic feed (such as cottonseed cake) must be strictly controlled and detoxified. Otherwise, even if it theoretically meets the standard, it cannot actually guarantee the quality of pigs. Nutritional requirements also affect pig growth and feed utilization.

Fourth, pay attention to palatability. The quality of palatability directly affects pig feed intake. Therefore, when formulating feeds, use more palatable feeds and use less, and use less to more peculiar smells and poor palatability feeds. Gradually increase the adaptation process to make the pigs as short as possible. Eat inside. In addition, when changing the feed or ratio, it should be carried out slowly. Sudden changes will reduce palatability, cause indigestion, and affect growth.

Fifth, the variety should be diversified. In order to ensure perfect nutrition and high feed digestion and utilization rate, it is best to use multiple feeds to match, and at least 4 to 5 kinds of refined, coarse, and green materials should be properly matched to play the complementary role of various feeds and improve feed utilization.

Six, the mix must be reasonable. When compounding feed, the ratio of refined and coarse feed should be appropriate, and a well-matched diet must achieve reasonable nutrition, moderate volume, and good palatability to ensure that pigs can eat and eat satisfactorily and meet nutritional needs. Otherwise, if the feed volume is too large and the nutritional concentration is not sufficient, the pig will be full and cannot meet the nutritional requirements. If the feed volume is too small and the nutritional concentration is large, the pig will not feel full and not quiet after eating, and it will affect the growth.

Seven, pay attention to the cellulose content of feed. Pigs are monogastric animals and have poor digestibility of crude fiber. Therefore, the content of cellulose in feed should be controlled according to the limit of breeding standards. Piglets should not exceed 4%, grow-finish pigs and breeding boars should not exceed 6% -8%, and breeding sows should not exceed 10% -12%.

Eight, coordination should be even. After the various raw materials are weighed according to the mixing ratio, firstly mix a large amount of basic materials such as corn, bran, cakes, etc., and then add other materials with a small amount to mix evenly. In the mixing process, it is necessary to mix repeatedly, especially for The various additives used in the diet should be divided into premixed methods, that is, first mixed with a small amount of auxiliary materials, then with more auxiliary materials, and then mixed into the entire diet repeatedly and uniformly, otherwise poisoning accidents will occur.

Nine, processing and modulation should be reasonable. The processing and preparation of raw materials is the key to improving feed digestibility. Self-made feed is generally powdered feed. Except for wheat bran and rice bran, corn, cakes, rice and other seed raw materials must be crushed. The degree is 1.5 mm. In addition, legume cakes and cotton cakes must be boiled to destroy trypsin inhibitor and gossypol toxin, and rapeseed cakes must be erucic acid removed to improve feed digestibility.

X. Scientific management of storage. Self-made feed should follow the principle of ready-to-use, because the mixed feed is not easy to be stored for a long time, and do not overdo it at one time. Generally, once every 3 to 5 days, it will cause loss of certain nutrients if the time is too long; special warehouses should be set up during storage, and the room should be ventilated, dry and dry, avoid moisture, prevent mold and deterioration, and reduce feed digestibility; To prevent contamination, the storage location and packaging feed utensils must be clean and non-toxic, and rats must not be bitten or stored with pesticides, fertilizers, etc.
