During pig rearing, feed poisoning is more common due to poor feed quality, malmoded feed and feed malmodulation. Once poisoned, it affects the pig's growth and development, but it causes death. This article lists common feeds that cannot be used to feed pigs for reference. First, a large number of piled and rotted succulent vegetables, beets, and green grass fodder for a long time, moldy and spoilage, or boiled in pots and jars overnight, will reduce the nitrate to nitrite. Green feed boiled quail preserved in the pot for 24 to 48 hours, the nitrite content of up to 200 ~ 400mg / kg (lethal dose of about 70 ~ 75mg / kg body weight), it should be fed immediately after the fresh feed or cooked, Do not squat in the pot. Second, fresh sorghum seedlings, corn seedling leaves and fresh flax leaves contain cyanogenic glycosides in these feeds. The feeds containing the work pods are piled, moldy, or frost-dried. Under the action of special enzymes in the plants, cyanide glycosides are hydrolyzed. And release hydrogen cyanide. The regenerated seedlings harvested after corn and sorghum are more harmful after frost. Hydrocyanic acid and cyanide are highly toxic, and even small amounts can cause pig poisoning. Third, the sprouting potato and its stems and leaves green stems and leaves, skin, especially embryos contain solanine, the highest in the epidermis of the potato block in the germ and the sun exposure to purple blue. Solanine stimulates the inflammation of the intestinal mucosa, which can damage the medulla and spinal cord and cause toxic paralysis. The use of potato germ as feed, germination, partial rot, or potatoes with green skin in production should be carried out by first trimming the germ, green skin, and decayed parts, washing them, and then feeding them. Fourth, sweet potato with black spot or sweet potato ground with black spotted sweet potato is best fed to pigs. Both raw and cooked pigs like to eat pigs, but ripening feeds almost twice as much protein than their raw counterparts. Sweet potatoes with black spot disease contain mycotoxins, which cause poisoning after eating, and when they are fed, black spots are cut off and washed. V. Raw soybeans and soybean cakes Beans containing antitrypsin, saponin, urease, etc., affect the palatability and feed digestibility, or even cause diarrhea, affect the weight gain, so the soybean meal cake Should be cooked. 6. Non-detoxified cotton kernel cakes and fresh cotton leaves contain gossypol in cottonseeds and leaves. During the extraction of cottonseeds, part of gossypol was excluded. The content of free gossypol varies according to different extraction methods. The lower the residual gossypol, the lower the gossypol, and the better the quality of the cottonseed cake. The lowest content of gossypol is 0.01%, and the highest is 0.6%. The content of free gossypol in the fed cotton kernel cake is not higher than 0.04%, and the maximum tolerable amount of free gossypol in the pig is 0.01%. In China's rural areas, “sandwich cakes†are steamed for a short time or fried without steaming. There is less destruction of free gossypol, and the content of gossypol in cakes is often as high as 0.2% to 0.3%. This type of cake must be added to the diet and free Gossypol can be fed with equal amounts of ferrous sulfate. The detoxified cottonseed cake was fed to the pig no more than 1kg per day, and the 3-month-old piglet did not exceed 100g. Fresh cotton leaves that have not been detoxified are fed with 3 kg of pigs per day, and piglets can be poisoned with 1.5 kg. VII. Non-toxic rapeseed cake The leek seed cake contains sulphur glucoside, which itself is non-toxic, but under neutral conditions, it is hydrolyzed to isothiocyanate under the action of mustard enzyme in rapeseed cake. Oxazolidinone and other harmful substances. The mustard enzyme is also present in certain gut bacteria, so feeding untreated sulfur-containing glucosinolates is more harmful. Excessive use of rapeseed cake will affect the weight gain and feed conversion rate of growing pigs. Generally, rapeseed cakes can be treated with high-temperature alkalization and control and quantity. In fattening pig feed, the proportion of rapeseed cake in refined feed should not exceed 20% to 25%. 8. Pestive Peanut Cakes The peanut cakes are most likely to be infected with Aspergillus flavus during storage and produce aflatoxin. Aflatoxin production occurs on peanut cakes, and even if cooked, it does not eliminate the toxicity. Nine, moldy corn, gluten, compound feed These moldy feed contains Aspergillus flavus, Aspergillus flavus, rust, etc., a variety of mold poisoning occurs after eating pigs. X. Excess Distiller's Grain Distillers The amount of pigs fed should not exceed 30% of the total amount of feed, otherwise alcohol poisoning may occur. In case of above-mentioned poisoning in pigs, one or more of the following may be used in combination: 1% methylene blue (methylene blue), 20% sodium nitrite, 20% sodium thiosulfate, 40% malotropine, And sodium, magnesium sulfate, glucose saline and other intramuscular or subcutaneous injection. Dosage according to the doctor's advice or according to the instructions and depending on the poisoning situation, but also according to the length of poisoning, the size of the pig with sodium thiosulfate, baking soda, magnesium sulfate and other lavage vomiting and diarrhea to relieve symptoms
