Abstract

All diets were based on feeds of fattening period pigs(LY x D, ca. 90 kg) with six treatments, which were the control, containing 5% beef tallow(C), 3% beef tallows and 2% perilla seeds oil(T1), 250 ppm vit. E(${\alpha}$-tocopheryl acetate) in T1(T2), 3% beef tallow and 2% squid viscera oil(T3), 250 ppm vit. E in T3(T4), and 3% beef tallow and 2% CLA(T5), respectively. Produced porks and their carcass characteristics were as follows. The daily gain of pigs was higher in T2 and 73 than any other treatments(p<0.05). Its T2 and T3 was 3.71 and 3.80 respectively, however, there was no significance in feed intake. The highest back fat thickness was shown in control group on market weight, while there was no significant difference on their initial weight. Loin-eye muscle area did not show any significant difference on initial weight and on market weight, however, its T5 was about twice as large as T2's. Content of triglyceride in blood was high in control group as compared to others; especially, the values for T3, T4 and T5 were significantly low(p <0.05). There was no significant difference in total cholesterol contents, and the ratio of HDL cholesterol/total cholesterol was higher in vit. E treated samples than untreated sample. Atherogenic index was high in sample with T3 and low in sample with T2. The perilla seed oil, squid fish oil, and vit. E decreased atherogenic index. Dressing percentage, back fat thickness, and grade did not show any significant difference(p >0.05); however, T2, C and T3, T1 and T5 showed 4.67, 4.29, 4.00 respectively, in grades.

비육후기 돼지(LY $\times$ D, 90 kg 전후) 사료에 C는 대조구로 우지 5%, T1은 우지 3%에 들깨유를 2%우지 대체하였으며, T2는 T1에 비타민 E($\alpha$-tocopheryl acetate)를 250 ppm 첨가하였다. T3는 우지 3%에 오징어유를 2% 우지 대체하였으며, T4는 T3에 비타민 E를 250 ppm 첨가하였다. T5는 우지 3%에 CLA 2% 우지 대체 첨가 급여한 돼지의 생산 및 도체형 질을 조사한 결과는 다음과 같다. 일당 증체량은 T2와 T3가 다른 구들보다 높았으며(P<0.05) 사료요구율은 처리간에 유의적인 차이는 없으나 T2와 T3가 각각 3.71, 3.80으로 다소 양호하였다. 생체에서 등지방두께는 개시 체중시에는 처리간에 유의적인 차이를 보이지 않았으나 출하체중 시에는 C가 다른 처리구들보다 유의적으로 두꺼워 개시체중 대비 출하체중 시의 등지방두께 증가폭 역시 C가 넓었다. 배최장근 단면적은 개시체중 시나 출하체중 시에는 유의적인 차이는 없었으나 증가면에서는 T5가 T2에 비해서 약 2배 정도인 13.35 $\textrm{cm}^2$로 가장 높게 나타났다. 혈액 중 Triglyceride함량은 C가 다른 처리구들보다 높았으며, T3, T4, T5가 유의적으로 낮았다(P<0.05). 총 콜레스테롤 함량은 처리구들간에 유의적인 차이를 보이지 않았으며, 총 콜레스테롤 대비 HDL-콜레스테롤 비율은 비타민 E를 첨가하지 않은 구보다 첨가한 구들이 높게 나타났다. 동맥경화지수(AI: Atherogenic index)는 T3가 가장 높고 T2가 가장 낮았으며, 들깨유와 오징어유에 비타민 E 첨가로 낮아졌다. 도체형질에서 지육율과 등지방두께 및 등급은 처리간에 유의적인 차이를 보이지 않았으나(p>0.05) 등급에 있어 T2는 4.67, C와 T3는 4.29, T1과 T5는 4.00 수준이었다.operational requirements and typical plasma parameters have been determined. Large arrays of individual tiny sources can be used to form large-area, atmospheric-pressure plasma sources. The simplicity of the method and the capability of operation without the need for the usual vacuum system and its associated limitations, provide a highly attractive option for new approaches to many different kinds of plasma applications, including plasma surface modification technologies. Here we review the background work that has been carried out in this new research field.row$물엿으로 제조한 정과의 순으로 red에 가까웠다. b값(Yellowness)은 전처리한 동아 300g에 물 1$\ell$, 물엿 475$m\ell$을 넣고 5시간 동안 제조한 군이 가장 높아 yellow에 가까웠고 전체적으로 물엿$\longrightarrow$설탕과 꿀$\longrightarrow$물엿과 설탕으로 제조한 정과의 순으로 yellow에 가까웠다. 5. 관능검사에서 단단하다고 평가된 정과가 색도에서 적색도가 높았다. 관능검사에서 색이 좋다고 평가된 정과가 색도에서 붉은 빛과 황색을 나타냈다. 관능검사의 단단한 정도(Hardness)와 씹힘성(Chewinwss)은 기계검사의 Texture인 최대절단력(Maximum
