*Department of Animal Resources Science, Daegu University, Gyeongsan 712-714, Korea ABSTRACTThis study was to assess the effect of sowing mixed legume forage and applying cattle manure on the productivity and feed value of whole-crop barley(WCB) as a representative of winter crops and to estimate feeding capacity of Korean native cattle (Hanwoo) per unit area by defining optimal application level of cattle manure for more fertile soil and manure recycling for the purpose of reduced environmental pollution and efficient production of organic forage contributable to production of organic animal products. Sowing mixed legume forage significantly(p<0.05) increased yields of dry matter(DM), crude protein(CP) and total digestible nutrients(TDN) for WCB compared to WCB alone sowing, but there was no difference between mixed sowing treatments. The yields of DM, CP and TDN were significantly(p<0.05) highest in 100~150kg N/hg. The CP and acid detergent fiber(ADF) contents were highest in mixed sowing with hairy vetch, followed by sowing mixed forage pea and WCB alone (p<0.05). There were no differences in CP and neutral detergent fiber(NDF) contents among cattle manure application levels. As nitrogen application level increased, ADF content increased(p<0.05), but TDN content decreased(p<0.05). Feeding capacity of organic Hanwoo(head/ha) weighing 450kg of body weight with 400g of daily gain significantly(p<0.05) increased due to mixed sowing with legume forage, and with increasing application levels of fermented cattle manure, feeding capacity significantly (p<0.05) increased. The results indicate that mixed-sowing of WCB and legume forage not only cut nitrogen application level of fermented cattle manure by over 50kg per ha but also increased their feed value and productivity, and feeding capacity. This would be contributable to diversity of forage resources as well as production of organic animal product by creating low cost and high quality of forage.(Key words :Legume mixture, Cattle manure, Barley, Productivity, Feeding capacity)
