How to improve the utilization rate of straw feed

Many farmers are used to smashing straw to livestock, which is unscientific. Because the straw in the crop contains a lot of lignin, cellulose and hemicellulose, it is difficult to be digested and absorbed. If the straw is treated before use to hydrolyze and expand the cellulose, the absorption and utilization rate will be greatly improved. Several commonly used methods of alkalization are introduced as follows: Ldg China Feed Industry Information Network - based on feed, serving animal husbandry

The caustic soda solution treatment method is also called caustic soda. It is dissolved in 80-100 kg of water per 100 kg of straw, dissolved in 80-100 kg of water, and placed at room temperature for 8 to 10 hours. The pulverized straw can also be sprayed, moistened, mixed, and stacked with a caustic soda solution to form a block feed for long-term use.

Lime solution treatment method: 12 kg of quicklime per 100 kg of mashed straw, add water 200-300 kg, then add 0.51 kg of salt, mix well and put it on the cement floor for 24~36 hours to use. Ldg China Feed Industry Information Network - based on feed, serving animal husbandry

The mixed liquid treatment method puts the whole straw into a layer of 15-20 cm thick, sprays 1.5% of caustic soda and the same concentration of quicklime mixture, so that the water content of the straw reaches about 70%, and then a layer after compaction. Spray on one floor and spray 80 kg of mixed liquid per 100 kg of straw. After 7 to 10 days of stacking, it can be used.

The ammonia water treatment method first smashes the straw and puts it into the crucible for compaction. Then, according to each kilogram of straw, 12 kg of 25% ammonia aqueous solution or 19 kg of 15% ammonia aqueous solution is used, and the temperature inside the crucible is not lower than 20 ° C. After sealing and storage for 5 days, it is taken out and air-dried, and the ammonia smell can be used after disappearing.
