Straw has low nutritional value and poor palatability, and cows do not like it. However, through processing, the volume and physicochemical properties of rice grassland can be changed, which facilitates cattle's food intake, increases their palatability and nutrition, enables cattle to grow fast, and improves the breeding efficiency.
Alkaline-acid combined treatment will put a short straw into a wooden barrel or concrete tank, add 1.5% to 2% sodium hydroxide solution, soak it out, put it into the cellar and compact it, remove it after 12 hours to 24 hours, and still put it. Into the cask or cement pool, soaked with 3% hydrochloric acid, and then discharge the solution, you can feed cattle. After such processing and processing, straw digestibility can be increased by 20% to 30%, and the utilization rate can be increased by more than 60%.
Ammoniad rice straw after ammoniated, crude fiber digestibility can be increased by 6.4% to 11%, protein digestibility can be increased by 10.6% to 12.2%, organic matter digestibility can be increased by 4.7% to 8%, while also adding protein Insufficient, the nutritional value reaches or approaches the level of blue hay. Production method: The short straw is put into a dry cellar and compacted. After adding 100 liters of rice straw, 12 liters of 25% ammonia or 6.5 liters of urea solution is sealed. After 5 days to 7 days, it is opened, ventilated, and the cows can be fed after the disappearance of ammonia.
Enzymatic Fermentation Fermentation of a short straw with cellulase preparation increased protein by 17.6%, crude fat by 62.8%, and the texture of straw became soft. After such processing and processing of rice straw, the increase of cattle feed intake can reduce the occurrence of gastro-intestinal diseases and at the same time promote the growth and rejuvenation.
Sodium Hydroxide and Lime Combine Treatment A short straw is sprayed with a 1.6% sodium hydroxide and 1.5% to 2% lime mixture and then 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 é“¡ Short straw: 3 kg of lime or hydrated lime per 100 kg, 1 kg to 1.5 kg of salt, 200 to 500 liters of water, mix well, soak for 2 hours to 3 hours, remove, and compact on the ground for 2 hours. Feed your cows in ~3 hours. Or soak the short straw in 1% to 2% lime water for more than 12 hours, then remove and feed the cow.
é“¡ Short processing The rice straw is chopped into small pieces 3 cm to 4 cm long, which not only facilitates mixing with the concentrate, but also helps the chewing of the cow, reduces energy consumption during chewing, increases contact with digestive enzymes, and improves digestibility.
