养猪的常识:
The common sense of pig raising:
一、杂交猪不能作种猪。这是因为杂交猪虽然体大,体质好,生长快,但因为它的遗传性能极不稳定,作种猪用,其后代会出现严重的性状分离,如饲料报酬降低,生长速度变慢,抗病能力减弱等。所以杂交猪不能用来作种猪。
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、颗粒饲料掺水喂。饲养实践中有的养猪户喜欢将颗粒料加水拌成粥料喂猪,这是不科学的。因为颗料饲料掺水后会,其营养成分会受到严重破坏,其营养价值大大降低。正确的方法是,先喂干料之后再饮水。
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、猪吃了就睡说明料好。猪有一定的生活习性,那就是吃料、活动、休息。特别是40公斤以下的小猪,每天中午前后都要有一定的玩耍。吃了就睡可能是在饲料中添加了镇定剂(如氯丙嗪),猪吃这些饲料后,破坏了其正常生理功能,猪因麻醉而睡觉。同时,镇静剂对猪机体会起到降低血压、降低体温和减少降心跳次数的作用,影响猪的正常代谢作用,并且镇定剂类药物在猪体内有残留,对消费者健康极为不利。
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 |
