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.

注意日糧體積與豬采食量的關(guān)系衡量飼料體積大小可用豬飼料干物質(zhì)含量計算。按豬每100公斤體重每日需飼料干物質(zhì)2.5公斤～4.5公斤計算，青料、粗料、精料三種飼料的干物質(zhì)需5∶3∶2，如一頭150公斤重的懷孕母豬，需飼料干物質(zhì)按5公斤計算，則2.5公斤干物質(zhì)來自青料(青料6公斤可得干物質(zhì)1公斤)，1.5公斤干物質(zhì)來自粗料，1公斤干物質(zhì)來自精料。

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.

做到大豬預(yù)混料適口性好，容易消化預(yù)混合飼料中，如含能量和蛋白質(zhì)較高，含粗纖維少，則適口性好，容易消化;相反，含能量和蛋白質(zhì)低，含粗纖維多，則適口性差，難以消化。在配豬飼料時，宜多采用青飼料，少用粗飼料，并且配合的粗飼料要求品質(zhì)好。

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.

根據(jù)不同豬群選用不同類型的日糧一般來說，仔豬、種公豬、催肥階段的育肥豬，可選用精料型，即精料可占日糧總重的百分之50以上;繁殖母豬、后備母豬可選用青料型，即青飼料可占日糧總重的百分之50以上;架子豬可選用糠麩型，即糠麩類飼料可占日糧總重的百分之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.

豬飼料誤區(qū)一：催肥階段大量喂豆餅或花生餅。

One mistake of pig feed: a large number of soybean cakes or peanut cakes are fed in the fattening stage.

很多養(yǎng)豬戶存在一個不科學(xué)的飼喂觀念，即在豬催肥階段大量喂豆餅或花生餅，他們認為這樣喂豬才能長得快、肉才結(jié)實，其實這是錯誤的。催肥階段豬生長要點是長脂肪，而不是長肌肉，因此不需要大量的蛋白質(zhì)飼料。

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.

如果催肥階段大量喂蛋白質(zhì)飼料，豬在胃腸道內(nèi)必須把蛋白質(zhì)含氮部分脫去，其他不含氮的部分才能轉(zhuǎn)化為脂肪，但脫氮要多耗能量。另外，豆餅或花生餅內(nèi)含大量的不飽和脂肪酸，多喂后，能使豬的脂肪變軟且發(fā)黃，根本不會使肉結(jié)實，反而降低了肉的品質(zhì)。餅類飼料的市場售價比其他飼料高，多用會增加飼料成本，這本身就是一種浪費。

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.

誤區(qū)二：采用熟飼料喂豬。

Mistake 2: feed pigs with cooked feed.

生飼料喂豬技術(shù)早已普及，但不少農(nóng)村養(yǎng)豬戶今仍采用熟飼料喂豬的飼養(yǎng)模式，他們認為豬吃熟食易長油，其實不然。飼料煮熟后，維生素幾乎全部被破壞，豬飼料中的蛋白質(zhì)老化變性。據(jù)統(tǒng)計，飼料在煮熟的過程中有百分之20的營養(yǎng)成分損失掉，青飼料中的營養(yǎng)成分損失更大，如果在燜煮時久放鍋內(nèi)，飼喂時還會出現(xiàn)亞硝酸鹽中毒，造成豬死亡。

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.
