      過期的豬用濃縮料使用后果是什么?

      來源:http://www.king4arab.com/ 日期:2020-09-15 發布人:sanwa8

      我們都知道飼料有貨架期,一般的飼料貨架期是6個月,不同的季節,不同的產品有不同的貨架期,所以在使用飼料前要觀察飼料的貨架期。如果使用過期的飼料,會導致牲畜中毒,甚至死亡;同時,豬飼料中的霉菌生長會消耗飼料中的營養和能量,減少和破壞飼料中的維生素、蛋白質和氨基酸,極少量的霉菌也能破壞飼料的風味,產生腐臭氣味,對動物健康產生不良后果。那么使用過期的提要有什么危險呢?

      We all know that there is a shelf life for feed. Generally, the shelf life of feed is 6 months. Different products have different shelf life in different seasons. Therefore, we should observe the shelf life of feed before using feed. If the expired feed is used, it will lead to livestock poisoning and even death; at the same time, the growth of mold in pig feed will consume the nutrition and energy in the feed, reduce and destroy the vitamin, protein and amino acid in the feed, and a very small amount of mold can also damage the flavor of feed, produce putrid odor, and have adverse consequences on animal health. So what's the danger of using expired feeds?
      過期飼料的主要危害有:
      The main hazards of expired feed are as follows:
      (1)有害微生物和霉菌毒素水平過高會對動物健康產生影響:
      (1) High levels of harmful microorganisms and mycotoxins can affect animal health
      過期飼料中常見的問題是霉菌,主要由黃曲霉、赭石曲霉、禾本科鐮刀菌和青霉引起。霉菌在生長繁殖過程中會產生大量毒素,主要包括黃曲霉毒素、赭曲霉毒素、forma毒素和嘔吐毒素。食用后,動物的生產性能會下降,這將在很多方面對動物造成傷害,甚至導致嚴重的死亡。例如黃曲霉毒素是一種劇毒物質,對動物肝臟有很強的破壞作用。霉變的癥狀因飼料的霉變程度、食用動物的多少和食用時間長短而不同,輕的人出現腸胃炎、拉肚子、懷孕的雌性動物流產,重的人出現神經癥狀甚至死亡。
      Mold is the common problem in expired feed, mainly caused by Aspergillus flavus, Aspergillus ochraceus, Fusarium graminearum and Penicillium. During the growth and reproduction of mold, a large number of toxins are produced, including aflatoxin, ochratoxin, forma toxin and vomit toxin. After eating, the production performance of animals will decline, which will cause harm to animals in many aspects, even lead to serious death. For example, aflatoxin is a highly toxic substance, which has a strong destructive effect on animal liver. The symptoms of mildewing vary with the degree of mildewed feed, the number of edible animals and the length of time consumed. Mild people suffer from gastroenteritis, diarrhea, and miscarriage of pregnant female animals. Severe people have neurological symptoms and even death.
      (2)過期的飼料會造成營養價值的損失和風味的變質:
      (2) Expired feed will cause the loss of nutritional value and flavor deterioration
      飼料過期發霉,不僅會導致霉菌產生大量代謝毒素,霉菌在繁殖過程中還會消耗、分解飼料中的營養物質,使飼料質量下降。在高溫高濕條件下,還能刺激脂肪酶、淀粉酶、蛋白酶等水解酶的活性。在霉菌、飼料酶等因素的協同作用下,可加快飼料中營養物質的分解速度,嚴重降低營養價值。例如,一些霉菌可以顯著降低受感染谷物中維生素B、維生素E或某些氨基酸的含量。過期發霉飼料還可使感官性狀惡化,如刺激性氣味、酸味、色差、粘稠污物等,嚴重影響適口性。

      Moldy feed will not only lead to a large number of metabolic toxins produced by mold, but also consume and decompose nutrients in feed in the process of reproduction, resulting in the decline of feed quality. Under the condition of high temperature and humidity, it can stimulate the activities of lipase, amylase, protease and other hydrolases. Under the synergistic action of mold and feed enzyme, the decomposition rate of nutrients in feed can be accelerated and the nutritional value can be seriously reduced. For example, some molds can significantly reduce the content of vitamin B, vitamin E or some amino acids in infected grains. Expired moldy feed can also worsen sensory properties, such as pungent odor, sour taste, color difference, viscous dirt, etc., which seriously affects palatability.
      此外,如果飼料中含有油脂,過期的飼料由于季節、溫度等原因,容易引起飼料中油脂發臭。飼養這些飼料會給畜禽造成應激,而腐臭或過期的飼料中含有一些有機酸、游離酸等小分子物質,會刺激畜禽神經系統引起興奮,從而產生跳躍或不睡覺的不良反應。
      In addition, if there is oil in the feed, the expired feed will easily stink due to season, temperature and other reasons. Feeding these feeds will cause stress to livestock and poultry, and putrid or expired feed contains some small molecular substances such as organic acids and free acids, which can stimulate the nervous system of livestock and poultry, and cause excitations, thus causing adverse reactions of jumping or not sleeping.
      過期飼料有許多危害,因此農民必須高度重視,決不要聲稱使用過期飼料。在飼養過程中,應根據養殖動物的數量和采食量合理購買和妥善保存飼料,避免在飼養過程中發霉,避免過期浪費飼料。
      There are many hazards of expired feed, so farmers must attach great importance to it and never claim to use expired feed. In the feeding process, feed should be reasonably purchased and properly preserved according to the number and feed intake of the breeding animals, so as to avoid mildew in the feeding process and waste feed after expiration.
