Nutrients distribution patterns in different parts of 36 oat varieties

The contents of moisture，ash，crude protein，watersoluble sugar，ether extract，calcium，phosphorus，crude fiber，neutral detergent fiber and acid detergent fiber in leaf，seed and stem of 36 varieties of forage oats were studied in alpine meadow area of Tianzhu County. The results showed that the content of moisture, ash, crude protein，soluble sugar and calcium in leaf were 6.36%，9.28%，19.82%，13.71% and 0.25% respectively, which were significantly（P0.05）higher than seed and stem. The ether extract and phosphorus contents in seed were 4.48% and 0.25% respectively, which significantly (P0.05) higher than that in leaf and stem. The crude fiber, neutral detergent fiber and acid detergent fiber contents in stems were 35.62%，65.18% and 56.40% respectively, which were significantly（P0.05）higher than that of leaf and seed. It could be concluded that the order of nutrition value of different parts were leaf seed stem.
