養豬的常識:
The common sense of pig raising:
一、雜交豬不能作種豬。這是因為雜交豬雖然體大，體質好，生長快，但因為它的遺傳性能極不穩定，作種豬用，其后代會出現嚴重的性狀分離，如飼料報酬降低，生長速度變慢，抗病能力減弱等。所以雜交豬不能用來作種豬。
1. A hybrid pig can not grow a pig. This is because the hybrid pig is large, healthy and fast, but because its genetic performance is extremely unstable, as a pig for breeding, the offspring will have serious character separation, such as lower feed return, slow growth, and weak resistance to disease. So hybrids can't be used as breeding pigs.
二、顆粒飼料摻水喂。飼養實踐中有的養豬戶喜歡將顆粒料加水拌成粥料喂豬，這是不科學的。因為顆料飼料摻水后會，其營養成分會受到嚴重破壞，其營養價值大大降低。正確的方法是，先喂干料之后再飲水。
Two. Feed the pellet feed with water. In practice, some pig farmers like to mix pellets and water into porridge to feed pigs, which is unscientific. As the feed is mixed with water, its nutrients will be severely damaged, and its nutritional value will be greatly reduced. The right way is to feed dry ingredients before drinking water.
三、豬吃了就睡說明料好。豬有一定的生活習性，那就是吃料、活動、休息。特別是40公斤以下的小豬，每天中午前后都要有一定的玩耍。吃了就睡可能是在飼料中添加了鎮定劑(如氯丙嗪)，豬吃這些飼料后，破壞了其正常生理功能，豬因麻醉而睡覺。同時，鎮靜劑對豬機體會起到降低血壓、降低體溫和減少降心跳次數的作用，影響豬的正常代謝作用，并且鎮定劑類藥物在豬體內有殘留，對消費者健康極為不利。
Three, the pig eats to sleep to explain the material well. Pigs have a certain habit of life, that is, eating materials, activities and rest. In particular, pigs under 40 kilograms have a certain amount of play every day before and after noon. After eating, sleeping may be a tranquilizer (such as chlorpromazine) added to the feed. After eating these feedstuffs, pigs destroy their normal physiological functions, and pigs sleep because of anesthesia. At the same time, tranquilizers can reduce blood pressure, reduce body temperature and reduce the number of heartbeat, affect the normal metabolism of pigs, and the sedative drugs have remained in pigs, which is extremely adverse |
