1. Cut short and long Straw, sweet potato vine, grass, hay, green vegetables, straw, etc., need to be cut short before they can be used to feed livestock. The straw for feeding cattle should be cut into 2 - 3 cm; the green vegetables fed with pigs should be cut into 1 - 2 cm; and the sweet potato can be made into 1 cm or so. Generally, it should be short and not too long, so as to achieve the feeding effect of "three cuts in the grass, no material and no sputum". If there are impurities, sediment, etc., wash and sieve. 2. Crushing and assisting digestion Grain (seed), sweet potato, cassava, etc. as feed must be crushed and ground to feed, to help digestion. The degree of pulverization should be determined according to the type of feed and livestock. The feed of pigs and cattle can be pulverized or 1-2 mm of medium or coarse particles; the chicken material should be ground into granules. Sweet potato and cassava can be cut into pieces and dried, then crushed. Sweet potatoes can also be beaten and fed. 3. Soaking to soften Corn, wheat, sorghum, bean cake and other feeds are best soaked in light salt boiling water for a while before feeding, so that it can be softened and then fed, which saves feed and is easy to digest. Generally, the ratio of material to water is 1:2. The length of the soaking time should be determined according to the season and the type of feed. The hot summer soaking time should be short to prevent the feed from decaying and deteriorating. 4. Cooking and tune the taste Broad bean, pea and soybean seed feed, which is processed by cooking. Practice has shown that soybeans are cooked, destroying anti-trypsin in soybeans, enhancing palatability, increasing digestibility and nutritional value, and increasing effective methionine and cystine in soy protein, increasing the biological value of protein. . However, the cooking time should not be too long, usually about 50 minutes. 5. Roasted crispy sweet Roasting is mainly a method of processing the concentrate to feed the piglets. The grain feed, especially the cereal grain feed, after a high temperature furnace of 130-150 ° C for a short time, part of the starch is converted into dextrin, which improves the utilization rate of starch, and can eliminate harmful bacteria, and the feed is sweet and delicious. Crisp appetite, good feeding effect. 6. Silage preservation and good The green material is stored in various pots, ponds and tanks, and fermented under anaerobic conditions to produce lactic acid. It can ensure the nutrients in the green fodder and improve the utilization and digestibility of the green fodder. It is also an effective measure to regulate the shortage of green feed in the peak season and off-season, and to supply the off-season green and sweaty feed.
