In order to make up for the indigestion caused by the lack of gastric acid in weaned piglets, the feed should be acidified. 1% - 3% citric acid or lactic acid can be added to drinking water or feed to reduce the pH value of feed to 5, or 0.3% pepsin can be added to feed, which can not only promote digestion, but also inhibit the propagation of enteropathogenic microorganisms.

發(fā)酵處理

Fermentation treatment

取小蘇打、甜酒曲、海蛸粉、辣蓼各50克，六一散3袋，茶葉5克，貫眾，山藥、茯苓、陳皮各250克，葡萄糖500克，分別研磨混勻，再加入5個雞蛋清、6千克細米糠拌勻，加水調和手握緊能成團，松手即散（含水量65%）時，裝入容器壓緊發(fā)酵，溫度必須控制在35℃~45℃之間，冬天溫度低需要蓋塑料薄膜和其他保溫物。3天后，料呈黃色并且有濃烈甜蘋果芳香氣味時，即為自制“藥曲種”，敞開放在陰涼處晾干備用。喂時，按粗飼料粉40%、麥麩10%、骨粉2%、魚粉2%、玉米45%、復合飼料添加劑（微量元素）一袋的比例，每50千克飼料中拌入自配“藥曲種”150克，另加清水50千克調和，溫度、濕度與“藥曲種”相同，然后把飼料裝入容器內經(jīng)24小時發(fā)酵，待產生濃烈甜酒蘋果香味時，就可取用飼喂，每日按4次喂給，每次喂2千克~3千克，并在每次吃完后搭喂些青綠多汁飼料。

Take 50g of baking soda, sweet wine koji, octopus powder and Polygonum hydropiper, 3 bags of 61 powder, 5g of tea, 5g of Guanzhong, 250g of yam, tuckahoe and tangerine peel, 500g of glucose, grind and mix them respectively, then add 5 egg white and 6kg of rice bran, mix with water until it is tight enough to form a group. When you loosen your hand, it will be loose (with 65% water content), put them into a container to press and ferment, and the temperature must be controlled at 35 ℃ ~ 45 ℃ In winter, plastic film and other heat preservation materials shall be covered for low temperature. After 3 days, when the material is yellow and has strong sweet apple aroma, it is self-made "medicinal koji", which is put in the shade to dry. During feeding, according to the proportion of 40% coarse feed powder, 10% wheat bran, 2% bone meal, 2% fish meal, 45% corn and one bag of compound feed additive (trace element), 150 g of self prepared "medicinal koji" is mixed into every 50 kg feed, and 50 kg of clear water is added for blending. The temperature and humidity are the same as that of "medicinal koji". Then the feed is put into a container and fermented for 24 hours to produce strong sweet wine and apple flavor, It can be fed with 4 times a day, 2-3 kg each time, and some green and juicy feed after each meal.

注意事項

matters needing attention

（1）選用的原料品種要盡可能多 原料品種多可起到營養(yǎng)物質的互補作用，但要注意豬對原料中營養(yǎng)物質的利用效率。

(1) It is necessary to select as many varieties of raw materials as possible to play a complementary role in nutrients, but attention should be paid to the utilization efficiency of nutrients in raw materials.

（2）飼料原料的質量要符合標準 可按照國標采購原料，切忌圖便宜而采購劣質原料。

(2) Feed raw materials can be purchased according to the national standard if their quality is up to the standard. It is forbidden to purchase inferior raw materials because they are cheap.

（3）盡可能使用本地廉價飼料原料 各地方的飼料原料資源不盡相同，有些廉價的飼料原料如米糠、豆腐渣等，都可以加以利用，以降低養(yǎng)殖成本。

(3) As far as possible, the use of local cheap feed raw materials varies from place to place. Some cheap feed raw materials, such as rice bran and tofu dregs, can be used to reduce the breeding cost.

（4）飼料原料的供應要貨源充足 對于某些時有時無的原料，更好要避免使用，因為經(jīng)常更換原料，可對豬只造成應激癥。

(4) The supply of feed raw materials should be sufficient. For some raw materials that are sometimes unavailable, it is better to avoid using them, because frequent replacement of raw materials can cause stress on pigs.

（5）注意飼料原料的適口性 雖然有的原料很廉價，但適口性不好，要注意限制這類原料的用量。反之，對于那些適口性非常好的原料，也要考慮限制喂量，以防過食而出現(xiàn)消化方面的問題。

(5) Pay attention to the palatability of feed raw materials. Although some raw materials are cheap, their palatability is not good. Pay attention to limit the amount of such raw materials. On the contrary, for those raw materials with good palatability, it is also necessary to consider limiting the amount of feed to prevent digestive problems caused by overeating.

（6）嚴格按照飼養(yǎng)標準設計配方，切忌隨意性 飼養(yǎng)標準是根據(jù)飼養(yǎng)試驗結果而制定的標準，比較有權威性的標準有美國的NRC標準，英國的ARC標準以及我國的國標。

(6) The formula is designed in strict accordance with the feeding standards, and random feeding standards are not allowed. The authoritative standards are NRC standards of the United States, arc standards of the United Kingdom and national standards of China.

（7）混合攪拌要均勻 有些添加量少的原料要行預混合，然后再添加到大料中進行混合。

(7) Mixing and mixing should be uniform. Some raw materials with small amount should be premixed first, and then added to the bulk for mixing.

糖化處理

Saccharification treatment

玉米、大麥、高粱等精料，都含有豐富的淀粉，如果進行糖化處理，可使其中一部分淀粉轉化為麥芽糖，不僅可以改善飼料適口性，而且也更容易消化。先把粉碎后的精料放入容器內，然后倒入2倍~2.5倍80℃~90℃的熱水充分攪拌成糊狀，為了不使飼料溫度迅速下降，可在飼料表面撒上一層厚約5厘米的干料，蓋上木蓋或塑料薄膜，使溫度保持在55℃~60℃，約需3小時~4小時即可使飼料糖化，糖化好的飼料，儲存時間更好不要超過14小時，以隨制隨喂為宜，以免酸敗變質。

Corn, barley, sorghum and other refined materials are rich in starch. If saccharification is carried out, some of the starch can be converted into maltose, which can not only improve the palatability of feed, but also be easier to digest. First put the crushed concentrate into a container, and then pour 2 ~ 2.5 times of 80 ℃ ~ 90 ℃ hot water into a paste. In order not to reduce the temperature of the feed rapidly, spread a layer of dry material with a thickness of about 5cm on the surface of the feed, cover it with a wooden cover or plastic film, keep the temperature at 55 ℃ ~ 60 ℃, and it takes about 3 ~ 4 hours to saccharify the feed. The best storage time is for the saccharified feed Do not exceed 14 hours. It is better to feed as you make it to avoid rancidity.
