Abstract:In order to determine livestock with grass, reduce grazing pressure in Qinghai Plateau, and carry out fattening work of cattle and sheep "West pasture Raised in east". 60 Qinghai Tibetan sheep aged 5~6 months were randomly dividedinto three groups with 20 sheep in each group. On the basis of the same supplementary concentrate,oat hay, oat-wrapped silage grass and wrapped whole-plant corn silagewere respectively fed for 30 d. The results were as follow:(1) The crude protein(CP), crude fat(EE) and crude ash(CA) of oat-wrapped silage grassincreased by 94.23%, 95.30% and 31.53%, respectively, and the crude fiber(CF) and nitrogen-free extract(NFE) decreased by 11.14% and 6.07%, respectively. CP, EE, Ca and NFE of wrapped whole-plant corn silage increased by 70.73%,62.42%, 7.83% and 24.23%, respectively, and CF decreased by 44.75%. CP, EE, Ca and CF of wrapped oat silage increased by 13.77%, 20.25%, 21.97% and 34.36%, respectively, and NFE decreased by 24.38%.(2) The average daily forage intake and crude protein intake of wrapped oat silage were 3.41 kg and 85.33 g, which were significantly higher than those of oat hay(P<0.01), and significantly higher than that of wrapped whole-plant corn silage(P<0.05), and the increase of crude protein intake was not obvious(P<0.01).(3) Average daily gain of wrapped oat silage and wrapped whole-plant corn silage was 163.08 g and 136.45 g, which were significantly higher than that of oat hay(P<0.01). The average profit of wrapped oat silage was 55.05 yuan and 29.4 yuan higher than that of oat hay.The daily gain of wrapped oat silage was not significantly higher than that of wrapped whole-plant corn silage(P>0.05), but the average profit increased by 57.13%.The increase was not obvious(P>0.05), but the average profit increased by 57.13%. The results showed that the forage quality and palatability of oat and whole-plant corn roughage by silage fermentation could improve fermentation quality and palatability, the nutrients and components of green forage were basically retained, forage intake, meat and milk yield were increased, and the economic benefits of breeding were improved. It is worth popularizing and applying in Qinghai cattle and sheep "West pasture Raised in east".
