본 연구는 쑥 펠렛 사료 급여에 따른 돼지의 성장율과 육질에 미치는 영향을 구명하고자 거세돈과 비거세돈에게 각각 대조구, 쑥 펠렛 3%, 쑥 펠렛 5%씩을 첨가급여하여 60일간 사양한 후 실험한 결과는 다음과 같다. 일당증체량에서 거세돈구 및 비거세돈구의 쑥 펠렛 사료 급여구가 대조구보다 유의적으로 높았다(p<0.05). 사료요구 율은 거세돈구가 비거세돈구보다 낮았고, 거세돈구의 경우는 쑥 펠렛 첨가에 따라 낮아지는 경향을 보였다. 전처리구간의 돈육의 일반성분은 조지방 함량을 제외하고 처리구간에 차이가 없었고, 그 중 거세돈구는 쑥 펠렛 급여에 따라 조지방 함량이 낮아져 유의성이 인정되었다(p<0.05). 전단력과 관능검사는 거세돈구가 비거세돈구보다 높아 유의차가 있었고(p<0.05), 또한 쑥 펠렛 급여구는 대조구보다 크게 향상되었다(p<0.05). 거세돈구의 경우 연도와 향미는 쑥 펠렛 3.0% 급여구가 가장 좋게 나타났다. 돈육의 카뎁킨 함량은 거세돈구가 비거세돈구보다 더 높은 경향이었고, 쑥 펠렛 첨가 수준이 증가함에 따라 높아지는 경향을 나타내었다. To investigate the effect of dietary mugwort pellet on the growing performance and meat quality barrow (T1) and boar (T2) were alloted into six treatments : 1) commercial feed, 2) T1-1 and T2-1 (commercial feed supplemented with 3.0% mugwort pellet), 3) T1-2 and T2-2 (commercial feed supplemented with 5.0% mugwort pellet). They were fed experimental diets for 60 days before slaughtered. Meat samples were taken in wrap package and stored at 4$\pm$1$^{\circ}C$. Daily gain in both groups (T1 and T2) were higher than those of the control (p<0.05). Feed conversion tended to be lower in barrow group than boar group and tended to be decreased according to supplementation of mugwort pelleted diet in barrow group. In both barrow and boar groups, proximate compositions of pork were not sigificantly different, except for crude fat. Crude fat content was tended to be low in barrow when fed mugwort pelleted diet. Shear force value and sensory properties were siginificantly higher in barrow group than in boar group (p<0.05) and these results were also seemed due to great fed mugwort pelleted aiet(p<0.05). In the barrow group, values of tenderness and flavor were the highest in pigs fed diet supplemented with 3.0% mugwort. The catechin content of pork tended to be higher in boar group than in barrow group and catechin tended to increase with supplementation of mugwort in the diet.

Virtualization allows multiple commodity operating systems to share on a single physical machine. Resource allocation among virtual machines is a key to determine virtual machine performance. To satisfy time-sensitive task on a domain, hypervisor needs to observe the resource requirements and allocates proper amount of CPU resources in a timely manner. In this paper, we propose a realtime credit scheduler for latency sensitive application on virtual machines. The key idea is to register a time event in the Xen hypervisor. Experiment result shows that the proposed scheme is superior to Credit scheduler.

김병기,김영직,Kim Byung-Ki,Kim Young-Jik 한국축산식품학회 2005 한국축산식품학회지 Vol.25 No.1

Effects of supplemental charcoal powder and vitamin A on physico-chemical properties in 24 Hanwoo steers were investigated. The Hanwoo steers were randomly assigned to one of the three dietary treatments : 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 2% charcoal powder and 0.2% vitamin A) 3) T2 (commercial feed with 2% charcoal powder). Crude fat content of proximate chemical composition in longissimus muscle was increased at control but moisture of control was rather lower than that of treatment groups (p<0.05). The WHC (water holding capacity) in longissimus muscle was tended to increase in control and shear force was higher in T2 (p<0.05). However, effects of diets charcoal power and vitamin A on pH were not found (p>0.05). Tenderness and flavor of sensory evaluation was improved significantly in control with peculiar and savory taste of Hanwoo being more emphasized. But Juiciness were not difference by treatments. When Hanwoo steers were fed with dietary charcoal powder and vitamin A, the palmitoleic acid and linoleic acid contents were higher compared with that of control (p<0.05), but oleic acid was higher in control than others. 본 시험은 거세한우에 대한 활성탄과 비타민 A의 첨가급여가 육질에 미치는 영향를 구명하기 위하여 거세 한우 총 24두를 공시하여 대조구, 활성탄 2%와 비타민 A 0.2%를 혼합급여한 T1구 그리고 활성탄 2% 급여구인 T2구로 3개 처리구에 각 8두씩을 배치하여 14개월간 사양시험을 실시하였고, 등심부위 근육을 공시하여 이화학적 특성을 조사하였다. 일반성분 중에서 대조구의 조지방 함량은 높았으나 상대적으로 수분 함량은 처리구에 비해 낮은 함량을 나타내었다(p<0.05). 등심부위 근육의 보수성은 대조구에서, 전단력은 T2구에서 높은 경향이었다(p<0.05). 그러나 pH는 처리구 사이에 특별한 변화가 없었다. 활성탄과 비타민 A의 첨가급여는 관능평가에서 연도, 육향에서 개선 효과는 없었으며 대조구가 처리구에 비해 유의적으로(p<0.05)높은 결과를 나타내었다. 지방산에서 palmitoleic acid와 linoleic acid 함량은 활성탄 또는 비타민 A 첨가구가 대조구보다 유의적으로 높았으나(p<0.05), oleic acid는 대조구가 다른 처리구보다 더 높은 경향이었다.

본 연구는 거세 한우에 대한 육성기의 양질 조사료(티머시 건초)의 급여 효과를 구명하기 위하여 거세우 20두를 공시하여 대조구, 시험구로 2개 처리구를 두고 생후 5개월령부터 28개월령까지 24개월간 비육시험를 실시한 결과는 다음과 같다. 28개월령 시험종료 시기의 체중은 대조구가 669.70kg, 시험구가 681.75 kg이었고, 일당 증체량은 시험구가 (0.83 kg) 대조구(0.81 kg)보다 다소 높은 경향이었다. 육성기의 두당 1일 조사료섭취 량은 시험구(4.27 kg)가 대조구(3.80kg)보다 크게 높은 경향이었다. 도축후 배최장근 단면적과 육량등급, 육질등급은 시험구(각 $85.62 cm^2$, 2.20 점, 2.20점)가 대조구(각 $81.29 cm^2$, 2.00점, 1.60 점)보다 크게 높아 통계적인 유의차 인정되었고(p<0.05), 육성기때의 양질 조사료 급여가 영향을 미친 것으로 사료된다. Effects of feeding high quality roughage (timothy hay) in growing period on growth performance and carcass characteristics during 24 month (5 month from 28 month to) in twenty of Hanwoo steers were investigated. The hanwoo steers were randomly allotted to 2 treatments (10 heads/treatment) ; rice straw group (control) and timothy hay group (treatment). The final body weights of rice straw group and timothy hay group on 28 month were 667.70 kg and 681.75kg, respectively. The daily gain of total period was slightly higher in timothy hay group (0.83kg ) than in rice straw group (0.81 kg). The daily roughage intake in the growing period was tended to be higher in timothy hay group (4.27kg ) than rice straw group (3.80 kg). The carcass grades (yield grade and quality grade) and Longissimus dorsi area were significantly higher in timothy hay group ($85.62 cm^2$, 2.02 and 2.20 point) than in rice straw group ($81.29 cm^2$, 2.00 and 1.60 point respectively) (p<0.05), and were affected by the feeding with high quality roughage in the growing period.

김병기,정창진,Kim, Byung-Ki,Jung, Chang-Jin 한국축산식품학회 2007 한국축산식품학회지 Vol.27 No.3

본 연구는 비육한우 32두(거세우 16두, 암소 16두)를 대상으로 (C-1구 거세우의 일반사료 : C-2구 암소의 일반사료 : T-1구 거세우에게 야생쑥 2%첨가 : T-2구 암소에게 쑥 2%첨가) 4개 처리구를 두고 14개월간(생후14개월-27개월) 비육시험한 결과는 다음과 같다. 27개월 시험종료 체중에서 대조구인 C-1구, C-2구는 각각 648.6, 623.1kg이었고, 처리구인 T-1구, T-2구는 각각 663.3 kg 및 620.7 kg으로서 T-1구가 가장 높았고, 총 증체량과 일당증체량에서도 T-1구가 각각 342.4 kg과 0.88 kg으로 가장 높았다. 1일 두당 총 사료섭취량은 대조구인 C-1구 및 C-2구와 처리구인 T-1구 및 T-2구가 각각 9.35, 9.09, 10.08 및 9.69 kg으로 T-1구가 가장 높았고, 사료요구율에서는 C-1구(11.28) > T-1구(11.48) > C-2구(11.52) > T-2(12.57)순으로 낮았다. 혈중 총콜레스테롤, GOT, GPT, 글리코스 및 BUN은 대체로 시험개시전보다 시험개시후가 더 높은 경향이었고, 특히 시험개시후의 총 콜레스테롤, GOT 및 glucose 함량은 처리구가 대조구보다 낮았다 (p<0.05). 도체중은 처리구(344.11-378.08 kg)가 대조구(342.71-369.70 kg)보다 높은 경향이었고, 등지방두께는 처리구(12.75-14.75 mm)가 대조구(15.76-16.00 mm) 보다 얇아진 반면에 배최장근 단면적은 처리구$(84.25-87.88cm^2)$가 대조구$(84.00-85.25cm^2)$보다 넓어졌다. 그 중에서 T-1구가 각각 14.75 mm와 $87.88cm^2$로 가장 좋았으며, 육량 및 육질등급은 처리구(각각, 2.02-2.50점, 2.85-3.05점)가 대조구(각각, 1.80점, 2.80-2.55점)보다 높았다. 본 시험의 결과를 종합해 볼 때 거세한우에게 쑥첨가는 일당증체량 증가, 도체중, 배최장근 단면적 및 육질개선 효과가 있는 것으로 판단된다. This study was conducted to determine the effect of mugwort powder supplementation on the fattening performance and carcass characteristics during a 14 month period (from 14 months to 27 months after birth) in 32 heads of fattening Hanwoo. Fattening Hanwoos were randomly assigned 4 treatments (8 heads/treatment): C-1 [(control (0%) with Hanwoo steers)], C-2 [(control (0%) with Hanwoo heifers)], T-1 (supplementation with 2.0% mugwort powder with Hanwoo steers) and T-2(supplementation with 2.0% mugwort powder with Hanwoo heifers). The final body weights for C-1, C-2, T-1 and T-2 at 27 months were 648.6kg, 623.1kg, 663.3kg and 620.7kg, respectively. The total gain and the daily gain were highest in the T-1 group (342.4 kg, 0.88 kg). Hanwoo steers were not significantly different from Hanwoo heifers. The feed intake for the C-1, C-2, T-1 and T-2 groups were 9.35 kg, 9.09 kg, 10.08 kg and 9.69 kg, with the T-1 value being highest. The feed conversion ratios were as follows: C-1 (11.28) > T-1 (11.48) > C-2 (11.52) > T-2 (12.57). The concentrations of total cholesterol, GOT, GPT, glucose and BUN in blood serum during the fattening period were higher after than before the experiment The total cholesterol, GOT and glucose after completion of the experiment were higher in the treatment groups than the control groups (p<0.05). The carcass body weight was higher in the treatment groups than the control groups. The back fat thickness was lower in the treatment groups (12.75-14.75mm) than the control groups (15.76-16.00mm), and the longissimus muscle area was higher in the treatment groups $(84.25-87.88cm^2)$ than the control groups $(84.00-85.25cm^2)$ with the highest over-all values in the T-1 group (p<0.05). The yield grade and quality grade point were higher in the treatment groups (2.02-2.50, 2.85-3.05 point, respectively) than the control groups (1.80, 2.55-2.80 point, respectively). In conclusion, the effects of feeding dietary mugwort powder to Hanwoo steers improved the ADG, carcass body weight, longissimus muscle area and quality grade.

김병기,하재정,이준구,오동엽,정대진,황은경,김수정,안용근,Kim, Byung Ki,Ha, Jae Jung,Yi, Jun Koo,Oh, Don Yep,Jung, Dae Jin,Hwang, Eun Gyeong,Kim, Soo Jung,Ann, Yong Geun 한국식품영양학회 2016 韓國食品營養學會誌 Vol.29 No.6

This study was a report on 60 heads of Hanwoo steers(5 treatments ${\times}$ 4 heads ${\times}$ 3 repeats). Their start weights were $361.2{\pm}14.39kg$ to $380.5{\pm}27.33kg$; 12.7 to 13.6 months of age. The aim was to investigate the effect of herbal probiotic supplementation on the weight, blood composition, meat quality and immunity in beef. In case of body weight gain, con. 1 plot(183.8 kg) in the early fattening stage, T3 plot(115.1 kg) in the middle fattening stage, and T2 plot(163.3 kg) in the late fattening stage significantly increased(p<0.05). There was a statistically significant difference in the blood content of T-Cho and IgG: con. 1 plot and T1 plot in the early fattening stage, T3 plot and T2 plots in the middle fattening stage, and con. 2 plot and T1~T3 plots in the late fattening stage had higher blood content than that of other treatment plots (p<0.05). In addition, the carcass weight was highest in the T1 plot and T2 plot among the total treatment plots(p<0.05). However, no statistical significant difference was observed in the different treatments; all individual treatment plots(T1~T3 plots) were somewhat higher than the control plots(con. 1~con. 2 plots) with respect to the carcass quantity and carcass quality. Combining and analyzing all results revealed that the dietary addition of herbal probiotics for Hanwoo steers had a positive effect on the improvement of weight, amount of meat, meat quality and immunity.

한우 거세유무 및 도축월령에 따른 비육능력 및 도체의 이화학적 특성 비교

김병기,정대진,이지홍,황은경,최창본,Kim, Byung-Ki,Jung, Dae-Jin,Lee, Ji-Hong,Hwang, Eun-Gyeong,Choi, Chang-Bon 한국축산식품학회 2011 한국축산식품학회지 Vol.31 No.2

The current study was conducted to compare the growth performance and physico-chemical characteristics of Hanwoo bulls and steers of different slaughtering ages. Thirty-six Hanwoo (average age, 13-mon) were allocated into either a bull or steer group (18 animals/group). Each group was sub-divided into 26-, 28-, and 30-mon-old age groups (six animals/group). Surgical castration was performed in the steer group immediately after the experimental groups were assigned. Growth performance of the animals, as well as carcass characteristics and fatty acid composition of M. longissimus dorsi were determined. Cold carcass weights increased as carcass slaughtering age increased in both Hanwoo bulls and steers (p<0.05). Backfat thickness was thickest (p<0.05) in 28-mon-old Hanwoo bulls and 30-mon-old steer, and the M. longissimus dorsi area was widest (p< 0.05) in 28-mon-old Hanwoo bulls and steers. Marbling score, cooking loss, and water holding capacity (WHC) were higher (p<0.05) in 30-mon-old Hanwoo bulls and steers as slaughtering age increased. The shear force value was highest in 30-mon-old Hanwoo bulls and 26-mon-old Hanwoo steers compared to that in other groups. The unsaturated fatty acid composition in M. longissimus dorsi was significantly (p<0.05) higher in 28- and 30-mon-old Hanwoo bulls and steers than that in other groups. The results suggest that castration, even at late stages of Hanwoo development, improved beef carcass quality grade, and that no difference in beef quality grade had occurred (marbling score and WHC) in 28- and 30-mon-old slaughtering age Hanwoo steers. 본 연구는 한우의 거세유무 및 도축월령에 따른 비육능력 및 도체의 이화학적 특성 비교를 구명하기 위하여 생후 13개월령의 비육한우 36두(비거세한우 18두 - 3처리 ${\times}$6두; 거세한우 18두 - 3처리 ${\times}$두)를 공시하여 생후 26개월, 28개월, 및 30개월령까지 비육한 후, 도체특성, 도체의 이화학적 특성 및 지방산 조성을 조사하였다. 도체의 냉도체중은 도축월령이 길어짐에 따라 비거세우와 거세우 모두 증가하였다(p<0.05). 등지방 두께에서 비거세우군은 28개월령이, 거세우군은 30개월령이 가장 두껍게 나타났고(p<0.05), 배최장근 단면적에서 비거세우군과 거세우군 모두 28개월령 때가 가장 넓게 나타났다(p<0.05). 근내지방도, 가열감량 및 보수력은 양 처리군 모두 30 개월령 도축할 때 가장 높았고(p<0.05), 비육기간이 길어질수록 높아지는 경향이었다. 전단력의 경우 비거세우군은 30개월령일 때에, 거세우군에서는 28개월령에 높았다. 도체의 불포화 지방산(unsaturated fatty acid, UFA)은 양 처리군에서 28개월령과 30개월령이 유의적으로 높았다(p<0.05). 이상의 연구결과를 종합해 볼 때, 한우의 장기비육에 있어서 늦게라도 거세를 실시하면 뚜렷한 도체등급의 개선 효과가 있으며, 거세비육우의 도축월령은 육질적측면(마블링 스코어와 보수력)에서 생후 28개월과 30개월령 간에는 거의 차이가 없었다.

김병기,이지홍,정대진,조광현,황은경,김수민,Kim, Byung-Ki,Lee, Ji-Hong,Jung, Dae-Jin,Cho, Kang-Hyun,Hwang, Eun-Gyeong,Kim, Soo-Min 한국축산식품학회 2010 한국축산식품학회지 Vol.30 No.5

거세 재래흑염소를 각 처리구별로 8두씩 배치하여 총24두(3처리$\times$8두)를 대상으로 대조구(무첨가)와 시험구인 T1구(한방제재 1%첨가)와 T2구(한방제재 2% 첨가)로 구분 배치하여 총 500일간 비육 시험한 결과는 다음과 같다. 비육 전기간(500일간) 동안의 총 증체량과 일당증체량은 T2가 28.30 kg과 0.057 kg으로 타 처리구보다 가장 높았다. 총 사료섭취량에서도 T2구가 519.20 kg으로 크게 높았으며, 사료요구율은 18.35으로 사료효율성이 가장 좋게 나타났다. 도체율은 T1구가51.10%로 가장 높았고(p<0.05), 흑염소 등심육의 가열감량과 드롭로스는 대조구가 시험구보다 크게 높았다(p<0.05). 콜레스테롤 함량은 시험구가 대조구보다 더 높은 경향이었지만 통계적인 유의차는 없었다(p>0.05). 또한 관능검사의 연도, 향미, 조직감 및 염소 특이취는 시험구가 대조구보다 크게 낮아져 (p<0.05), 종합적인 관능평가에서는 시험구(3.71점, 3.90점)가 대조구(4.82점)보다 더 좋게 되었다(p<0.05). 지방산 조성의 단가불포화지방산(MUFA)/포화지방산(SFA)과 불포화 지방산(UFA)/포화지방산(SFA)의 비율에서는 시험구가 대조구보다 더 높은 경향이었으나 통계적인 유의차는 없었다. This study was carried out to investigate the effect of different herb resource powders on meat quality and sensory properties in Korean native black goat for 500 d. The experimental treatment was arranged with 24 heads (3 treatment/8 heads) by control group, T1 and T2 group respectively (Control, not added herb powders; T1, 1% added herb powders; T2, 2% added herb powders). Total weight gain for the Korean native black goat was the highest in T2 group feeding for 500 days, and daily gain tended to be similar to the total weight gain. The total feed intake were the highest as 519.20 kg in T2 group, although feed conversion showed 18.35 in the T2 group, which means it had the best feed efficiency compared to the other treatment groups. The carcass rate was higher in the T1 group (51.10%) than in the other groups (p<0.05). The cooking loss and drip loss of Korean native black goat was the highest as 34.72% and 3.83% in the control group (p<0.05). However, total cholesterol amounts in the treatment group were not significantly different from, although tended to be higher than, the control group (p>0.05). Also, the overall sensory evaluation of the treatment group revealed low scores, meaning more meat flavor than those of the control in tenderness, flavor, texture, and black goat off-flavor and overall evaluation (p<0.05). Total synthesis evaluation was higher for the treatment group (3.71, 3.90 point) than that of the control group (4.82 point) (p<0.05). The MUFA/SFA ratio of the treatment group was not significantly different from, although tended to be higher than, the control group
