Farmers with pig feed from the matters needing attention

Master the pig breeding standards

不同生产目的的猪以及不同生长阶段的猪，对营养物质的需要量不同，因而应根据猪的生产目的、年龄、体重等，选择不同的饲养标准来配制日粮。

Production for different purposes in different growth stages of pig and pig, the required amount of nutrients should be different, so according to the pig production purposes, such as age, weight, the choice of different feeding standard diets.

合理选择原料

Reasonable selection of raw materials

在选择饲料原料时，必须注意以下几点：一是注意原料的种类和用量。原料品种应多样化，以利发挥各种原料之间的营养互补作用。常用的猪饲料的比例为谷物类如玉米、稻谷、大麦、小麦、高粱等，占50%-70%，糠麸类如麦麸、米糠等出10%-20%，豆饼、豆粕占15%-20%，有毒性的饼、粕如棉籽饼、粕及菜籽饼相应小于10%，种猪不宜使用棉籽饼、粕。动物蛋白质饲料如鱼粉、蚕蛹粉等占3%-7%、草粉、叶粉小于5%，贝壳粉或石粉占 3%-35%，骨粉占2%-25%，食盐要小于05%。二是注意饲料原料的特性。要掌握原料的有关特性，如适口性，饲料中有毒有害成分的含量，以及饲料的污染、有无霉变等情况，适口性差、含有毒素的原料用量应有所限制，严重污染的、霉变的原料不宜选用。三是重视经济性原则，应本着因地制宜，就地取材的原则，充分利用当地原料资源。四是注意原料的体积。为了确保猪能够吃进每天所需要的营养物质，所选原料的体积必须与猪消化道容积相适应，如果体积过大，猪一天所需的饲料量吃不完，从而造成营养物质不能满足需要，同时还会加重消化道的负担；若体积过小，虽然营养物质得到满足，但猪没有饱感，表现烦燥不安，从而影响生长发育。

In the choice of feed raw materials, must pay attention to the following points: one is to pay attention to the types and amount of raw materials. Varieties of raw materials should be diversified, with the use of complementary nutrition effect of various kinds of raw materials. The proportion of pig feed used for cereals such as maize, rice, barley, wheat, sorghum, accounting for 50%-70%, such as wheat bran, rice bran bran bran etc. 10%-20%, soybean cake, soybean accounted for 15%-20%, toxic cake, cottonseed cake, Po Ru meal and rapeseed corresponding to less than 10%, pig is the use of cottonseed cake, cake. Animal protein feed, such as fish meal, silkworm chrysalis powder accounted for 3%-7%, grass powder, leaf powder is less than 5%, shell powder or powder for 3%-35%, bone meal accounted for 2%-25%, the salt should be less than 5%. Two is the characteristics of attention of feed raw materials. To master the relevant characteristics of raw materials, such as palatability, content of toxic and harmful ingredients in feed, and feed contamination, no mildew and so on, poor palatability, containing the toxin of the raw materials used should be restricted, mildew serious pollution, raw materials should be used. The three is to pay attention to the principle of economy, should be based on the principle of suit one's measures to local conditions, obtain raw material locally, making full use of the local raw material resources. The four is to pay attention to the volume of material. In order to ensure that the pig could eat into the daily nutrients required the selection of raw materials, the volume must be consistent with the digestive tract of pigs volume, if the volume is too large, the amount of feed of pig needs each day can not eat it, thereby causing the nutrients can not meet the need, also will increase the burden on the digestive tract; if the volume is too small nutrients, although be satisfied, but the pig without satiety, showing irritability, thus affecting the growth and development.

加工调制要合理

Processing and modulation should be reasonable

像麦麸、米糠、鱼粉、骨粉等粉状原料外，玉米、豆类、稻谷等籽实类原料应适当粉碎，生大豆不能直接喂猪，必须炒熟或煮熟后才能使用。

Like wheat bran, rice bran, fish meal, bone meal and other powder raw material, corn, beans, rice and other grain class raw material should be properly crushed raw soybean, not directly to feed the pigs, must be used to be cooked or cooked.

原料混合要均匀

The mixture of raw materials to the uniform

各种原料必须混合均匀，才能保证猪吃进所需的各种营养物质。尤其是加有预混饲料时，如混合饲料混合不均匀，容易造成猪药物或微量元素中毒。

All raw materials must be mixed evenly, can guarantee the pig to eat a variety of nutrients into the desired. Especially with premixed feed, such as mixed feed is not mixed evenly, easy to cause the pig medicine or trace element poisoning.
