The preparation method of salinized straw: Take clean and dirt-free dry straw without musculoskeletal deterioration, and then short it with a rake, and then use a hammer mill (mesh diameter 12-15mm) to comminute the straw. Should not be too fine, grass powder length 10-20mm, width 1-3mm, too thin is not easy to ruminate. Excessively reduced feed intake results in waste. Then the crushed straw powder was added into 1% salt water, and an appropriate amount of warm water was added, and the mixture was evenly mixed. The degree of wetness was grasped into a group by hand, and the degree was dispersed after loosening, and then piled and fermented. Can also be fed now, through the salinization of the straw to increase the straw nutrient price, is conducive to sheep feed intake and improve digestion and absorption rate. Feeding dose: Each sheep feeds 0.5kg each time. If it exceeds 0.5kg, it can be divided into 2 feedings. When feeding, it is necessary to add some concentrated feed. If it can be fed with a certain amount of silage, appropriate amount of feed additives and vitamins should be added appropriately. , the effect is better. According to experiments, the use of salted corn straw feed sheep, the test group than the control group daily gain can be increased by about 5% -10%, increase the economic efficiency of more than 15%. Each can only increase 30-50 yuan.
