The reasonable processing of straw-fed cattle can be cut into short sections of 3-4 cm in length, and the best condition is to feed the straw after alkalization, ammoniation or salinization. Alkalization method: The cut straw is placed in an aquarium or cement pond, and immersed in 1% quick lime water or 3% hydrated lime water. After 24 hours, it can be taken out and fed. Amination method: soak straw with 3% ammonia, after 7-10 days, remove the straw and let it dry. Salinization method: every 100 kilograms of rice straw (cut into small pieces) with salt 0.6-1 kg, warm water 150-160 kilograms, fully stirred evenly, into the cement pool compaction, fermented about 1 day out of feeding cattle. Acidification and fermentation method: The cut straw was placed in a container, and 3% of the new spring probiotic liquid was added to ferment the cow for 2 days. Do not feed straw alone. The nutritional content of rice straw is not high. Even if the cattle are allowed to reach maximum feed intake, they cannot meet their nutritional needs. Therefore, a certain amount of green material should be fed or supplemented with some fine material containing more protein. Legume forage contains more calcium, which can make up for the shortage of calcium content in rice straw. Concentrate should be bean cake, corn, sorghum, etc., do not feed too much bran, especially wheat bran contains more phosphorus, long-term feeding is easy to destroy the body's calcium and phosphorus balance, resulting in decalcification of bone softening, serious can cause paralysis.
