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.

发酵处理

Fermentation treatment

取小苏打、甜酒曲、海蛸粉、辣蓼各50克，六一散3袋，茶叶5克，贯众，山药、茯苓、陈皮各250克，葡萄糖500克，分别研磨混匀，再加入5个鸡蛋清、6千克细米糠拌匀，加水调和手握紧能成团，松手即散（含水量65%）时，装入容器压紧发酵，温度必须控制在35℃~45℃之间，冬天温度低需要盖塑料薄膜和其他保温物。3天后，料呈黄色并且有浓烈甜苹果芳香气味时，即为自制“药曲种”，敞开放在阴凉处晾干备用。喂时，按粗饲料粉40%、麦麸10%、骨粉2%、鱼粉2%、玉米45%、复合饲料添加剂（微量元素）一袋的比例，每50千克饲料中拌入自配“药曲种”150克，另加清水50千克调和，温度、湿度与“药曲种”相同，然后把饲料装入容器内经24小时发酵，待产生浓烈甜酒苹果香味时，就可取用饲喂，每日按4次喂给，每次喂2千克~3千克，并在每次吃完后搭喂些青绿多汁饲料。

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.

注意事项

matters needing attention

（1）选用的原料品种要尽可能多 原料品种多可起到营养物质的互补作用，但要注意猪对原料中营养物质的利用效率。

(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）饲料原料的质量要符合标准 可按照国标采购原料，切忌图便宜而采购劣质原料。

(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）尽可能使用本地廉价饲料原料 各地方的饲料原料资源不尽相同，有些廉价的饲料原料如米糠、豆腐渣等，都可以加以利用，以降低养殖成本。

(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）饲料原料的供应要货源充足 对于某些时有时无的原料，更好要避免使用，因为经常更换原料，可对猪只造成应激症。

(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）注意饲料原料的适口性 虽然有的原料很廉价，但适口性不好，要注意限制这类原料的用量。反之，对于那些适口性非常好的原料，也要考虑限制喂量，以防过食而出现消化方面的问题。

(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）严格按照饲养标准设计配方，切忌随意性 饲养标准是根据饲养试验结果而制定的标准，比较有权威性的标准有美国的NRC标准，英国的ARC标准以及我国的国标。

(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）混合搅拌要均匀 有些添加量少的原料要行预混合，然后再添加到大料中进行混合。

(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.

糖化处理

Saccharification treatment

玉米、大麦、高粱等精料，都含有丰富的淀粉，如果进行糖化处理，可使其中一部分淀粉转化为麦芽糖，不仅可以改善饲料适口性，而且也更容易消化。先把粉碎后的精料放入容器内，然后倒入2倍~2.5倍80℃~90℃的热水充分搅拌成糊状，为了不使饲料温度迅速下降，可在饲料表面撒上一层厚约5厘米的干料，盖上木盖或塑料薄膜，使温度保持在55℃~60℃，约需3小时~4小时即可使饲料糖化，糖化好的饲料，储存时间更好不要超过14小时，以随制随喂为宜，以免酸败变质。

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.
