Comparison of production performance and feeding value of different oat varieties in Yudaokou, Bashang, Chengde

To screen out oat varieties suitable for production and utilization in the Yudaokou area of Bashang, Chengde, plant height, grass yield, leaf area, crude protein (CP), crude fat (EE), crude ash (Ash), neutral detergent fiber (NDF) content, acid detergent fiber (ADF) content, and relative feeding value (RFV) of eight imported oat varieties were analyzed. The results show that there were great differences in production performance and nutritional components of different oat varieties. Among them, the plant height of ‘Haymaker’ was significantly higher than that of other varieties (139.3 cm) (P < 0.05). The fresh grass production of ‘Everleaf 126’, ‘Haymaker’, and ‘Baler Ⅱ’ was higher; ‘Model’ and ‘Haymaker’ had higher hay production. Furthermore, the content of CP, EE, Ash, NDF, and ADF ranged from 4.22% to 7.17%, 2.08% to 2.89%, 3.01% to 6.27%, 54.63% to 65.66%, and 29.81% to 40.24%, respectively. The RFV of ‘Souris’ and ‘Baler’ was higher. Comprehensive evaluation of the indicators by the gray correlation method showed that the excellent varieties are ‘Everleaf 126’, ‘Haymaker’, and ‘Model’, which are the most suitable for planting in the Yudaokou area of Bashang, Chengde.
