Straw has low nutritional value and poor palatability, and cattle do not like to eat. However, through processing, the volume and physical and chemical properties of the rice grassland can be changed, which is convenient for cattle to eat, increase its palatability and nutrition, and can make cattle grow faster and improve breeding efficiency.
Alkali acid combination treatment Put the short straw into the wooden barrel or cement pool, add 1.5%~2% sodium hydroxide solution, then take it out, put it into the crucible and compact it. After 12 hours~24 hours, take it out and still put it. Into a wooden barrel or cement tank, soaked with 3% hydrochloric acid, and then discharged the solution, you can feed the cattle. After such processing, the straw digestibility can be increased by 20 to 30%, and the utilization rate can be increased by more than 60%.
After ammoniation treatment, the digestibility of crude fiber can be increased by 6.4% to 11%, the protein digestibility can be increased by 10.6% to 12.2%, the digestibility of organic matter can be increased by 4.7% to 8%, and protein can be supplemented. Insufficient, the nutritional value reaches or approaches the level of green hay. Production method: Put the short straw into a dry crucible and add 12 liters of 25% ammonia water or 6.5 liters of urea solution per 100 kg of straw, and fill it up and seal it. Open and ventilate after 5 days to 7 days, and the cows can be fed after the ammonia smell disappears.
Adding enzyme fermentation to the cellulase preparation in the short straw, the protein can be increased by 17.6%, the crude fat is increased by 62.8%, and the straw texture becomes soft. After the straw is processed and treated in this way, the feed intake of the cattle is increased, which can reduce the occurrence of gastrointestinal diseases, and at the same time promote the growth and rejuvenation.
The combination of sodium hydroxide and lime is used to spray a mixture of 1.6% sodium hydroxide and 1.5% to 2% lime with a sprayer and then compact. Spread the straw in turn and spray the mixture. After 1 week of stacking, the crude fiber digestibility can be increased by 30%.
Lime treated short straw with 3 kg of quicklime or slaked lime per 100 kg, salt 1 kg to 1.5 kg, add water 200 liters to 500 liters, stir evenly, soak for 2 hours to 3 hours, remove and place on the ground for 3 hours. You can feed the cows later. Or soak the short straw in 1% to 2% of the quicklime water for more than 12 hours.
