猪用浓缩料厂家介绍使用过期猪饲料的危害

来源:http://www.sanwangyoubanggen.com/ 日期:2021-02-25 发布人:sanwa8

我们都知道饲料都有保质期,一般饲料保质期在6个月,不同季节,不同产品其保质期不同,所以在使用饲料前要观看饲料保质期,因为过期的猪饲料会给养殖者带来严重的危害。那么,使用过期饲料有什么危害呢?来听听猪饲料厂家带来的详细介绍:

We all know that feed has a shelf life. Generally, the shelf life of feed is six months. Different seasons and different products have different shelf life. Therefore, we should watch the shelf life of feed before using feed, because expired pig feed will bring serious harm to breeders. So, what is the harm of using expired feed? Let's listen to the detailed introduction of pig feed manufacturers
过期饲料的主要危害有:
The main hazards of expired feed are as follows:
1、有害微生物及霉菌毒素超标,对动物健康产生影响
1. Harmful microorganisms and mycotoxins exceed the standard and have an impact on animal health
过期饲料容易发生的问题是霉变,引起饲料霉变的霉菌主要有黄曲霉菌、赭曲霉菌、禾谷镰刀菌、推展青霉菌等。动物采食后会降低生产性能,对动物产生多方面的危害,严重的甚至死亡。如黄曲霉素是剧毒物质,对动物肝脏有强烈破坏作用。霉变饲料中毒的症状因饲料的霉变程度、动物采食的多少和采食时间的长短而不同,轻者出现胃肠炎、拉稀,怀孕母畜流产,重者出现神经症状甚至死亡。
The problem of expired feed is mildew. The main molds causing feed mildew are Aspergillus flavus, Aspergillus ochraceus, Fusarium graminearum, Penicillium spreading and so on. After feeding, the production performance of animals will be reduced, which will do harm to animals in many aspects, even death. For example, aflatoxin is a highly toxic substance, which has a strong destructive effect on animal liver. The symptoms of mildewed feed poisoning vary with the degree of mildewed feed, the amount of food taken by animals and the length of time taken. Gastroenteritis and diarrhea occur in mild cases, abortion occurs in pregnant cows, and neurological symptoms and even death occur in severe cases.
2、过期饲料会造成饲料营养价值损失、风味劣变
2. Expired feed will cause loss of nutritional value and flavor deterioration
过期及发生霉变的饲料,在高温、高湿的外部环境下还可以激发脂肪酶、淀粉酶、蛋白酶等水解酶的活性,在霉菌、饲料酶等因素协同作用下,加快饲料中营养成分的分解速度,营养价值严重降低。如有的霉菌可使被感染的谷物中B族维生素,维生素E或某种氨基酸的含量显著下降,长期饲喂这种饲料可引起某些营养缺乏症。过期的霉变饲料还可以使感官性质恶化,如具有刺激气味、酸臭味道、颜色异常、黏稠污秽感等,严重影响适口性。
Under the external environment of high temperature and humidity, the expired and moldy feed can also stimulate the activities of lipase, amylase, protease and other hydrolases. Under the synergistic effect of mold, feed enzyme and other factors, the decomposition speed of nutrients in feed is accelerated, and the nutritional value is seriously reduced. For example, some molds can significantly reduce the content of B vitamins, vitamin E or some amino acids in infected grains. Long term feeding of this kind of feed can cause some nutritional deficiencies. Expired moldy feed can also worsen sensory properties, such as pungent smell, sour taste, abnormal color, thick and dirty feeling, which seriously affect palatability.
3,易造成饲料中脂肪和油脂出现酸败等情况
3. It is easy to cause rancidity of fat and oil in feed
如果饲料中含有油脂的话,过期饲料由于季节、温度等原因,易造成饲料中脂肪和油脂出现酸败等情况。饲喂这些饲料将造成畜禽应激,并且酸败或过期饲料中含有一些有机酸、游离酸等小分子物质将刺激畜禽神经系统造成畜禽兴奋,从而产生跳圈或不睡觉的恶习。
If there is fat in the feed, it is easy to cause rancidity of fat and oil in the feed due to season, temperature and other reasons. Feeding these feeds will cause livestock stress, and some organic acids, free acids and other small molecular substances in rancid or expired feeds will stimulate the nervous system of livestock and poultry, causing excitement of livestock and poultry, resulting in the bad habit of jumping circle or not sleeping.
经过猪饲料厂家带来的详细介绍,我们了解到过期饲料具有许多危害,因此养殖者务必高度重视,绝不能擅作主张使用过期饲料。在养殖过程中,要根据养殖动物的数量和采食量合理购买饲料并妥善保存,避免在贮存过程中发生霉变现象,也要避免饲料的过期浪费。
Through the detailed introduction of pig feed manufacturers, we know that expired feed has many hazards, so the breeders must attach great importance to it, and must not be good at advocating the use of expired feed. In the process of breeding, feed should be reasonably purchased and properly preserved according to the number and feed intake of breeding animals, so as to avoid mildew and waste of feed.
