猪用预混料如何选择才是正确的?

多样合理,保证营养十足。在喂猪的青料、粗料、精料三种猪饲料中,青料含水分多,体积大,易消化,适口性好,并含有多种维生素、矿物质和蛋白质;粗料体积大,粗纤维含量较高,配合合理,可增加饲料与消化液的接触面,并有通便作用,易使猪有饱胀感,但难以消化;精料的特点是体积小,营养价值高,易消化,但矿物质、维生素较缺乏。  

Variety and reasonable, ensure full nutrition. Among the three kinds of pig feed, including green fodder, roughage and concentrate feed, the green feed contains more moisture, larger volume, easier digestion, better palatability, and contains a variety of vitamins, minerals and proteins; the coarse feed has a large volume and a high content of crude fiber, which can increase the contact surface between feed and digestive fluid, and has the effect of catharsis, which makes pigs feel full but difficult to digest; Concentrate is characterized by small size, high nutritional value, easy to digest, but lack of minerals and vitamins.
注意日粮体积与猪采食量的关系衡量饲料体积大小可用猪饲料干物质含量计算。按猪每100公斤体重每日需饲料干物质2.5公斤~4.5公斤计算,青料、粗料、精料三种饲料的干物质需5∶3∶2,如一头150公斤重的怀孕母猪,需饲料干物质按5公斤计算,则2.5公斤干物质来自青料(青料6公斤可得干物质1公斤),1.5公斤干物质来自粗料,1公斤干物质来自精料。
Pay attention to the relationship between feed volume and pig feed intake. The feed volume can be calculated by dry matter content of pig feed. According to the daily feed dry matter of 2.5kg-4.5kg per 100kg body weight, the dry matter of green feed, coarse feed and concentrate feed is 5:3:2. If a 150 kg pregnant sow needs feed dry matter of 5 kg per day, 2.5kg of dry matter comes from green feed (1kg of green feed can get 1kg of dry matter), and 1.5kg of dry matter comes from roughage and 1kg of dry matter Self concentrate.
做到大猪预混料适口性好,容易消化预混合饲料中,如含能量和蛋白质较高,含粗纤维少,则适口性好,容易消化;相反,含能量和蛋白质低,含粗纤维多,则适口性差,难以消化。在配猪饲料时,宜多采用青饲料,少用粗饲料,并且配合的粗饲料要求品质好。
猪用预混料
To achieve good palatability of pig premix, easy to digest premixed feed, such as high energy and protein, less crude fiber, good palatability, easy to digest; on the contrary, low energy and protein, more crude fiber, poor palatability, difficult to digest. In the preparation of pig feed, green feed should be used more and roughage less, and the quality of the roughage should be good.
根据不同猪群选用不同类型的日粮一般来说,仔猪、种公猪、催肥阶段的育肥猪,可选用精料型,即精料可占日粮总重的百分之50以上;繁殖母猪、后备母猪可选用青料型,即青饲料可占日粮总重的百分之50以上;架子猪可选用糠麸型,即糠麸类饲料可占日粮总重的百分之50以上。
According to different pig groups, different types of diets are selected. Generally speaking, concentrate type can be selected for piglets, breeding boars and fattening pigs at fattening stage, that is, concentrate can account for more than 50% of the total diet weight; breeding sows and reserve sows can choose green diet type, that is, green feed can account for more than 50% of the total diet weight; Bran type can be selected for Jiazi pigs, that is, bran feed can account for more than 50% of the total diet weight.
猪饲料误区一:催肥阶段大量喂豆饼或花生饼。
One mistake of pig feed: a large number of soybean cakes or peanut cakes are fed in the fattening stage.
很多养猪户存在一个不科学的饲喂观念,即在猪催肥阶段大量喂豆饼或花生饼,他们认为这样喂猪才能长得快、肉才结实,其实这是错误的。催肥阶段猪生长要点是长脂肪,而不是长肌肉,因此不需要大量的蛋白质饲料。
Many pig farmers have an unscientific feeding concept, that is, they feed a large number of bean cakes or peanut cakes in the stage of pig fattening. They think that only by feeding pigs in this way can they grow fast and their meat can bear fruit. In fact, this is wrong. In the fattening stage, the main point of pig growth is to grow fat, not muscle, so it does not need a lot of protein feed.
如果催肥阶段大量喂蛋白质饲料,猪在胃肠道内必须把蛋白质含氮部分脱去,其他不含氮的部分才能转化为脂肪,但脱氮要多耗能量。另外,豆饼或花生饼内含大量的不饱和脂肪酸,多喂后,能使猪的脂肪变软且发黄,根本不会使肉结实,反而降低了肉的品质。饼类饲料的市场售价比其他饲料高,多用会增加饲料成本,这本身就是一种浪费。
If a large amount of protein feed is fed in the fattening stage, the nitrogen-containing part of protein must be removed in the gastrointestinal tract of pigs, and other non nitrogen containing parts can be transformed into fat, but the nitrogen removal needs more energy. In addition, the soybean cake or peanut cake contains a lot of unsaturated fatty acids, which can make the fat of the pig soft and yellow after being fed more. It will not make the meat strong at all, but will reduce the quality of the meat. The market price of cake feed is higher than that of other feeds. Multi use will increase feed cost, which is a waste in itself.
误区二:采用熟饲料喂猪。
Mistake 2: feed pigs with cooked feed.
生饲料喂猪技术早已普及,但不少农村养猪户至今仍采用熟饲料喂猪的饲养模式,他们认为猪吃熟食易长油,其实不然。饲料煮熟后,维生素几乎全部被破坏,猪饲料中的蛋白质老化变性。据统计,饲料在煮熟的过程中有百分之20的营养成分损失掉,青饲料中的营养成分损失更大,如果在焖煮时久放锅内,饲喂时还会出现亚硝酸盐中毒,造成猪死亡。
Raw feed technology has been widely used for a long time, but many rural pig farmers still use mature feed to feed pigs. They think that pigs eat cooked food and grow oil easily, but in fact, it is not. After the feed is cooked, almost all of the vitamins are destroyed, and the protein in the pig feed is aged and denatured. According to statistics, 20% of the nutrients are lost in the process of cooking, and the loss of nutrients in green feed is even greater. If it is put in the pot for a long time during stewing, nitrite poisoning will occur during feeding, resulting in pig death.
