石膏粉在饲料中的应用是什么

来源: 日期:2020-05-21 发布人:juyehe

  与动物所需的钙量相比,天然植物性饲料中的钙量通常是不足的。对于蛋、牛、羊和正在成长的小动物来说尤其如此。家禽在蜕皮期、长毛期、生长期对钙源的需求特别大,这个时候只要得到足够的钙源补充,对于动物的生长或其他方面都可以有较好的生长。因此,动物饲料中应注意钙的添加。硫酸钙(石膏粉)作为一种含钙矿物的饲料添加剂,在饲料工业中得到了广泛的应用。

  Compared with the amount of calcium required by animals, the amount of calcium in natural plant feed is usually insufficient. This is especially true for eggs, cows, sheep and growing animals. Poultry in molting period, long hair period, growth period of the demand for calcium source is particularly large, this time as long as sufficient calcium source supplement, for animal growth or other aspects can have better growth. Therefore, we should pay attention to the addition of calcium in animal feed. Calcium sulfate (gypsum powder), as a kind of feed additive containing calcium mineral, has been widely used in feed industry.

  动物体内的硫主要有利于含硫氨基酸、蛋氨酸等物质的形成。硫也是肝素。它含有硫磺脂肪、鸡蛋、羽毛、牛磺酸和胆汁。它在排毒过程中也起着重要的作用。动物的需要一般都是有机硫,所以蛋白质饲料是动物主要的硫源。但近年来,无机硫也被认为对动物有一定的营养价值。
  Sulfur in animals is mainly beneficial to the formation of sulfur-containing amino acids, methionine and other substances. Sulfur is also heparin. It contains sulfur fat, eggs, feathers, taurine and bile. It also plays an important role in the process of detoxification. Animal needs are generally organic sulfur, so protein feed is the main source of sulfur. But in recent years, inorganic sulfur is also considered to have certain nutritional value to animals.
  硫酸钙还具有预防和治疗某些疾病的作用。无水硫酸钙(石膏)兴安,大寒,有清热泻火,除干渴解渴外,尤长于清析气分的固热。夏季温度较高,因此在饲料中适当添加一定量的生石膏可以抑制神经应激反应,降低血管通透性,抗炎解热作用。猪、鸡等养殖作业可作为饲料添加剂,预防和控制热应激。饲料的用量一般为1%-2%。
  Calcium sulfate can also prevent and treat some diseases. Anhydrous calcium sulphate (gypsum) is used in Xing'an and in the cold. It can clear away heat and relieve fire. Besides thirst, it is better than the fixed heat of gas. The temperature is higher in summer, so adding a certain amount of gypsum to the feed can inhibit the nerve stress response, reduce the vascular permeability, anti-inflammatory and antipyretic effects. Pig and chicken can be used as feed additives to prevent and control heat stress. The amount of feed is generally 1% - 2%.
  国外使用硫酸钙作为饲料添加剂的历史很短,作为天然矿物饲料添加剂,国外长期使用天然沸石、膨润土、皂石、石灰石(碳酸钙)。硫酸钙的应用才刚刚开始。目前主要用于动物营养和牲畜饲养,并与其他饲料产品混合制成复合预混料。国外的硫酸钙作为饲料添加剂一般用于饲养牛、猪、鸡、兔等,是一种钙饲料,补充一般饲料中缺钙、缺硫,也是一种营养调节剂和载体,可预防疾病,促进生长发育,提高饲料利用率。硫酸钙作为一种经济的饲料添加剂,在一定程度上可以替代碳酸钙。
  The history of using calcium sulfate as feed additive in foreign countries is very short. As a natural mineral feed additive, natural zeolite, bentonite, saponite and limestone (calcium carbonate) have been used for a long time. The application of calcium sulfate is just beginning. At present, it is mainly used for animal nutrition and livestock breeding, and mixed with other feed products to make composite premix. Calcium sulfate, as a feed additive, is generally used to feed cattle, pigs, chickens, rabbits, etc. it is a kind of calcium feed to supplement the lack of calcium and sulfur in the general feed. It is also a nutrient regulator and carrier, which can prevent diseases, promote growth and development, and improve feed utilization. As an economic feed additive, calcium sulfate can replace calcium carbonate to some extent.
