ABSTRACT

In terms of food intake of mutton sheep, mutton grass has fast decomposition speed and high rumen pass rate, which cannot give full play to its advantages in a long time. High NDF prepared by high NDF and rapid ammonia treatment equipment began to show benefits. When the addition rate of ammonia straw exceeds 50%, it can be determined that the addition rate of ammonia straw is 75%. In this round of attempt, the 76% ammonification straw team had little food cost, but profit, the sheepgrass team invested capital and profit a lot, the 26% ammonification straw group had the highest feed cost sheepgrass group ranked second. This indicates the goals that can be achieved. It is possible to replace the sheep herb with a small amount of amidated straw. Research shows the transformation of DM and NDF, and the parabola is suitable for the data presented by experts. Between 2 days and 3 days, the degradation rate leveled off, and the loss rate of degradation in the rumen. This group increased rapidly within 0 to 6 hours, stabilized within 6 to 12 hours, and the DM loss rate increased rapidly within 12 to 72 hours. Consistent with the nutritional value and disappearance rate of NDF, ADF and other nutrients, CP in dry matter began to degrade rapidly within 0~6 hours, ADF in dry matter and half a day, the degradation rate leveled off, the loss rate of dry matter in rumen the group increased rapidly within 0~6 hours, stable within 6~12 hours, and the DM loss rate increased rapidly within 12~72 hours.
