가축분 관리는 현재 낙농 및 양돈농가의 중요 관심사로, 본 연구는 액상분뇨의 N 함량을 기준으로 시용수준을 달리하여 시용했을 때 사초용 연맥(Avena sativa L.)의 사초수량 및 품질을 구명하고자 7처리(화학비료표준구 120 k g N h a − 1 , 소 액상분뇨구 120, 240, 360 k g N h a − 1 돼지 액상분뇨구 120, 240, 360 k g N h a − 1 )를 난괴법 3반복으로 배치하여 1997년 수원에서 수행하였다. 액상분뇨의 시용수준이 중가될 수록 사초용 연맥의 초장은 높았으나, 건물 함량은 떨어졌다. 사초용 연맥의 건물 수량은 액상분뇨의 시용수준간에 유의적인 차이를 보였다(P<0.05) 조단백질 함량은 14.7에서 24.1% 였으며(P<0.05), 조단백질 수량은 돼지액상분뇨 360 k g N h a − 1 구>소 액상분뇨 360 k g N h a − 1 구>돼지 액상분뇨 240 k g N h a − 1 구 순이었다(P<0.05). ADF 함량은 소 액상분뇨구가 돼지 액상분뇨구에 비해 약간 높았고(P<0.05), NDF 함량은 소 액상분뇨구가 돼지 액상분뇨구에 비해 낮았다(P<0.05). 소 액상분뇨구의 상대사료가치(RFV)는 돼지 액상분뇨구와 비교하여 액상분뇨의 시용량이 증가됨에 따라 낮아졌다. 본 연구결과에 의하면 액상분뇨의 N 시용수준이 증가됨에 따라 사초수량도 증가된 것을 볼 수 있었다.

Manure management is a top priority on both dairy and swine farrns at present. This experiment was carried out to determine the effect of different types and N rates of liquid manure on forage yield and quality of oats(Avena sativa L.) in Suweon, 1997. Seven treatments consisting of chemical fertilizer 120 k g N h a − 1 , liquid cattle manure 120, 240 and 360 k g N h a − 1 , and liquid swine manure 120, 240 and 360 k g N h a − 1 were arranged in a randomized complete block design with three replications. As increasing N rate of the liquid manure, the plant height was increased, but dry matter content of oats was decreased as increasing liquid manure N rate. There were significant differences in dry matter yield of oats among the liquid manure N rates(P<0.05). Crude protein(CP) content of oats ranged from 14.7 to 24.1% (P<0.05), and CP yield was orderly ranked as liquid swine manure 360 k g N h a − 1 >liquid cattle manure 360 k g N h a − 1 >liquid swine manure 240 k g N h a − 1 (P<0.05). Acid detergent fiber(ADF) content of the liquid cattle manure treatment showed a slightly higher than that of the liquid swine manure treatment(P<0.05). Neutral detergent fiber(NDF) content of the liquid cattle manure treatment was lower than that of the liquid swine manure treatment(P<0.05). Relative feed value(RFV) of the liquid cattle manure treatment decreased with increasing liquid manure N rates compared with that of the liquid swine manure treatment. Based on the results of this experiment, it is indicates that to increase the N rates from liquid manure application could be obtained from the increase of forage yield.
