본 실험은 사료급여 종류가 동절기 우유의 생산량 및 조성분에 미치는 영향을 규명하기 위하여, 1998년 10월 부터 1999년 3월까지 실시하였다. 실험구 처리는 볏짚구(볏짚 위주 조사료＋농후사료: T1)를 대조구로 하여 옥수수 사일리지구(옥수수 사일리지 위주 ＋ 농후사료:T2) 및 TMR구(완전혼합사료: T3)를 상호 비교하였으며 그 결과를 요약하면 다음과 같다. 1. 우유 생산량은 T2(31.9$\pm$3.2kg) > T3(29.6$\pm$3.8kg) > T1구(22.5$\pm$2.0 순으로 높게 나타났다 (P<0.05). 그리고 산차별 우유 생산량은 T2 및 T3구는 3산에서(P<0.01), T1구는 4산에서 높은 유량을 나타냈다. 2. 유지율은 T3구가 3.79$\pm$0.31%로 가장 높았던 반면 T1구는 2.64$\pm$0.20%(P<0.01)로 가장 낮은 함량을 보였으며, 산차별로는 2 산차가 높은 경향치를 보였다. 3. 단백질 함량은 사료종류에 따라 유의적인 차이는 없었지만 T1구(3.17%$\pm$3.56%)에 비하여 T2(3.25$\pm$0.05%) 및 T3구(3.29$\pm$0.10%)가 높은 경향을 나타났으며(P<0.05), 산차에 따라서는 뚜렷한 차이는 보이지 않았다. 4. 무지고형분 함량은 T3(8.74$\pm$0.18%)>T2(8.47$\pm$0.22%)>T1구(8.56$\pm$0.04%) 순으로 나타났으며, 총고형분 함량은 T3(12.51$\pm$0.57%)>T1(11.71$\pm$0.62%) > T2구(11.52$\pm$0.55%) 순으로 나타났다. 그러나 상호간 유의차는 없었다. 5. 체세포 수는 T1구가 39.6$\pm$4.6${\times}$$10^4$Cell/ml 로 가장 높은 수치를 보였던 반면 T2구는 28.7$\pm$4.4 ${\times}$ $10^4$ Cell/ml로 가장 낮게 나타났다. 이상의 결과를 종합해 볼 때 볏짚구(T1)에 비하여 TMR(T3) 및 옥수수 사일리지(T3) 급여체계는 유량 증대 및 우유성분 함량을 높이는 데 매우 효율적인 방안으로 나타났다.

This experiments were carried out to determine growth characteristics, dry matter yield and voluntary intake of silage according to growth stage of Sorghum$\times$sudangrass(SSH) hybrid in mono-cropping and inter-cropping(C; com, T1; cutting of SSH at milk stage. T2; cutting of SSH at dough stage, T3; cutting of SSH at yellow ripe stage, T4; cutting of SSH and soybean at milk stage, T5; cutting of SSH and soybean at dough stage, T6: cutting of SSH and soybean at yellow ripe stage). Results obtained from these experiments are as follows; Plant length and leaf length of SSH(T2, T3, T4. T5 and T6)) were higher than C. T1 treatment was lower than it. C showed $2.3\~2.9$ times higher stem diameter as 29.5mm compare to SSH(T1, T2, T3, T4, T5 and T6). soybean(T4, T5 and T6) was lower in $4.3\~5.4$ times. But SSH of inter-cropping treatment(T4, T5 and T6) showed highly comparing with mono-cropping(T1, T2 and T3) at the same maturity. Leaf rate and stem hardness of SSH(T1, T2, T3, T4, T5 and T6) were lower than C. The fresh yield was high line with T2(72,320kg/ha), T1(69,103kg/ha), T3(68,333kg/ha) and C(57,988kg/ha), dry matter yield was high in line with T3(22.413kg/ha), T2(21,479kg/ha), C(19,252kg/ha) and T6(18,175kg/ha), (P<0.05). Protein dry matter yield was higher in T3(1,434kg/ha), C(1,386kg/ha)T5 and T6(1,345kg/ha) it was lower in T1(872kg/ha), (P<0.05). Crude protein of silage of T4 and T5 was higher than C, T2 and T3 were lower than it(P<0.05), while NDF content was not different. ADF content of T6 was higher than those of the other treatment. The highest hemi-cellulose among treatments was shown in T1 whereas T6 showed the lowest. Fresh intake of silge was 160.4, 155.8, 168.7, 172.9, 132.9, 158.7 and 185.2 g/BW for C, T1, T2, T3, T4, T5 and T6, respectively. Dry matter intake was high in line with T6(60.3g), C(153.8g), T3(53.6g), T5(47.8g), T2(46.8g), T4(35.2g) and T1(34.48g/BW), (P<0.05). Crude protein intake was high in line with T6(3.9g), T5(3.4g), C(3.4g), T2(2.9g), T3(2.9g), T4(2.6g) and T1(2.3g/BW), (P<0.05). As mentioned above the results, mono-cropping(T3) and inter-cropping(T5 and T6) could be recommended as increasing method of sorghum $\times$ sudangrass hybrid silage utilization when silage intake of dry matter and crude protein were considered.
