In southern China, straw is the main fodder for cattle after feeding. Through effective treatment, rice straw can change its original volume and physical and chemical characteristics, facilitate cattle's food intake, increase its palatability, and facilitate the digestion and absorption of nutrients. Straw processing methods are as follows: Alkali, acid combined treatment: The short straw into the barrel or cement pool, add 1.5% ~ 2% sodium hydroxide solution soaked out, into the kiln compaction, over 12 ~ After 24 hours, they were removed and still placed in wooden barrels or concrete pools. They were soaked with 3% hydrochloric acid, and the solution was discharged to feed the cows. The digestibility can be increased by 20% to 30%, and the utilization rate can be increased by more than 60%. Ammonia treatment: after straw ammoxidation, crude fiber digestibility can be increased by 6.4% to 11%, protein digestibility is increased by 10.6%~12.2%, and organic matter digestibility is increased by 4.7% to 8%, which can supplement protein deficiency, nutrition The value is at or near the level of blue hay. The production method is as follows: The short straw is put into a dry kiln for compaction, and 12 kg of 25% ammonia water or 6.5 kg of urea aqueous solution is poured per 100 kg of rice straw and filled and sealed. 5 to 7 days after opening, ventilation, etc. After the disappearance of ammonia taste can be fed cows.é“¡ Short: The rice straw is chopped into a 3 to 4 cm long section, which is good for chewing cows, reducing the energy consumed during chewing, increasing contact with digestive enzymes, improving digestibility, and mixing easily with cereal concentrates. Enzymatic Fermentation: Fermentation with a cellulase preparation in a short straw can increase the protein by 17.6%, crude fat by 62.89%, and the straw texture becomes soft and can be preserved for 2 years. Increased intake of cattle, can reduce gastro-intestinal diseases, and there is a role in increasing rejuvenation. Sodium Hydroxide and Lime are combined together: Short straw is sprayed with 1.6% of sodium hydroxide and 1.5% to 2% of Lime mixture using a sprayer and compacted. Straw is then added in sequence and the mixture is sprayed. After feeding for 1 week, the crude fiber digestibility can be increased by 30%. Lime treatment: For short straw, use lime or hydrated lime 3 kg per 100 kg, salt 1 to 1.5 kg, add 200 to 500 kg of water, stir well, soak for 2 to 3 hours, remove and compact on the ground, 2 to 3 hours You can feed cows later. Or soak the short straw in 1% to 2% quick lime for more than 12 hours and remove and feed the cow.
