This study, analyzed the general and minerals composition of kamut and investigated its effect on blood components in mice fed a high fat diet. The content of each general component of kamut was as follows: 11.02±0.75% water, 13.16 ±1.28% crude protein, 1.85±0.19% crude fat, and 1.97±0.13% ash. The leptin level was the highest in the HF group(30.00± 0.00 ng/mL) when compared to the control group. There was a significant decrease of 23.65±5.54 ng/mL in the HFK group when compared to the HF group (p<0.05). The blood LDL-cholesterol concentration was the lowest in the control group at 10.00±2.00 mg/dL. The level was highest in the HF group at 28.00±0.00 mg/dL when compared with the other groups (p<0.05). The aspartate transaminase (AST) level was significantly higher in the HFK group (179.33±173.88 U/L) than in the control (61.00±12.73 U/L) and HF groups (132.00±0.00 U/L). According to the results of this study, the consumption of kamut lowers the blood LDL-cholesterol level more than the consumption of wheat flour. Additionally, kamut contains antioxidant substances such as selenium and zinc, which are thought to contribute to vascular health and thus aid in maintaining good health. Therefore, it is necessary to develop a variety of health foods using kamut; it should be used as a functional food for the maintenance of good health.

This research was conducted to investigate the effects of feeding high and low forage diets with different forage sources on rumen fermentation characteristics and blood parameters of Holstein cows during the dry period. Eight Holstein cows were completely randomized assigned to two groups and repeated measurement was utilized in the analysis. Cows in two treatments were fed with diets with high (F:C = 70:30, 70F; forage source: mixed-sowing whole crop barley and Italian ryegrass silage, BIRG) and low (F:C = 55:45, 55F; forage source: tall fescue hay, TF) forage level. Rumen fluid pH was higher in 70F group. Levels of acetic acid, propionic acid, and butyric acid showed a similar pattern: from the lowest value at 07:30 h to the highest at 10:30 h and then decreased in both groups. The ratio of acetic acid to propionic acid was significantly higher (p < 0.05) in 55F group at 09:30 and 10:30 h. Rumen fluid NH3-N concentrations were significantly higher (p < 0.05) in 70F group at 09:30 and 10:30 h. Blood urea nitrogen was significantly higher (p < 0.05) in 70F group. It was concluded that BIRG based diet with a high forage level had no adverse effects on rumen fermentation, some blood chemical parameters, and immune system in dry Holstein cows and could be used as a forage source instead of imported TF.

농장동물복지형 한우 사양관리를 통한 고품질의 쇠고기 생산을 목표로 세계적인 트랜드에 부합하는 축산선진국으로 나아가기 위하여 본 시험으로 우방내 사육공간의 넓이차이에 따른 한우의 사양성적, 행 동특성 및 혈액성상에 미치는 영향을 비교·분석해 보았다. 16개월령의 한우 54두(암소 미경산공태우 및 거세우 각각 27두)를 공시하여 성별에 따라 사육공간의 넓이차이를 주기 위해 4두(8m2), 3두 (10.67m2) 및 2두(16m2)로 처리하여 9개월간 각각 3반복으로 완전 임의배치 후 실시하였으며, 한우 사 양관리 프로그램에 따라 사료급여를 하였다. 데이터 수집방법으로 증체량, 사료요구율 및 혈액분석은 2 개월 간격으로 반복하여 측정하였으며, 행동패턴 수집은 복수개체 추적방법 및 선택적 행동관찰법으로 기상청에서 제공한 맑은 날을 선정하여 15일간 녹화 후 분석에 이용하였다. 본 시험의 결과로, 사양성 적(체중, 일당증체량 및 사료요구율)의 경우 미경산공태우와 거세우 각각 20개월령과 18개월령 이후부 터 2두와 3두 처리구에서 모두 유의적(p<0.05)으로 향상되었다. 행동특성으로는 미경산공태우의 2두 처 리구에서 행동시간으로 기립행동은 유의적(p<0.05)으로 낮고, 횡와 및 걷기행동은 유의적(p<0.05)으로 높았다. 행동빈도에서는 음수, 자기몸핥기, 긁기, 몸비비기, 투쟁행동에서 유의적(p<0.05)으로 적게 나 타났다. 거세우의 2두 및 3두 처리구에서는 미경산공태우와 유사한 경향을 나타냈으나 유의적(p<0.05) 으로 섭식시간은 증가하고, 다른소핥기 및 몸기대기의 빈도는 유의적(p<0.05)으로 적게 나타났다. 혈액 성상으로 미경산공태우와 거세우의 4두 처리구에서 적혈구가 유의적(p<0.05)으로 낮았고, 콜티졸은 유 의적(p<0.05)으로 높게 나타났다. 또한, 미경산공태우의 헤모글로빈과 거세우의 백혈구 수치에서는 모 두 2두 처리구에서 유의적(p<0.05)으로 각각 높고 낮은 것으로 분석되었다. 이상의 결과를 종합하면 사 양성적, 행동특성 및 혈액성상 등의 전체적인 내용을 토대로 우사의 여유 및 표준우사의 우방크기를 고 려할 때 한우의 사육공간에서 관행사육인 4두 처리구(두당 8m2) 보다 미경산공태우는 2두 처리구(두당 16m2), 거세우는 3두 처리구(두당 10.67m2)로 사육하는 것이 적절하다고 판단되며, 본 시험결과는 추후 복지형 한우의 사양관리를 위한 기초자료로 활용할 수 있을 것으로 판단된다.

The objective of this study was to evaluate the effects of acute hypoxia on the physiological stress responses (plasma cortisol as the primary response, and hematocrit, hemoglobin, plasma glucose, sodium, chloride, osmolality, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) as the secondary responses) of Korean rockfish. The mortality in Korean rockfish started at 0.7 mg L-1 and 0.8 mg L-1 levels at 12℃ and 20℃, respectively. And the time required for the mortality in experimental fish was 274 and 148 minutes at 12℃ and 20℃, respectively. Levels of hematocrit, hemoglobin, AST, ALT, ion concentration, osmolality, glucose and cortisol had significantly increased with decreasing dissolved oxygen at 12℃ and 20℃.

The aim of this study was to investigate the effects of different rearing spaces on growth performances, behavioral traits, and blood parameters in Hanwoo (Korean Native Cattle) heifers and steers. The average daily gain and feed conversion ratio were measured to assess the growth performance. A total of 54 Hanwoo heifers and steers at 18 months old, were housed separately in groups of 2, 3 or 4 heads in a pen (32 m2) for nine months. In the case of the heifers, the growth performances were significantly (p<0.05) improved by increasing the 2 head group size with the exception of the 18 month old heifers. However, among the steers the growth performances were significantly enhanced (p<0.05) after 18 months of age, by increasing the 3 heads group size. In addition, the heifers in groups of 2 heads spent less time standing and more time lying down or walking, and also had a significantly (p<0.05) lower frequency of self-grooming, scratching, and fighting. These findings are similar to the results obtained for steers housed in 2 or 3 heads per group. The steers housed in 2, 3 heads groups spent more time feeding and consequently had a significantly (p<0.05) lower frequency of pair-wise grooming and Leaning. The heifers and steers housed in groups of 4 heads showed lowest red blood cell counts, but highest cortisol content with statistical significance at p<0.05. The heifers in groups of 2 heads had the highest hemoglobin concentrations (p<0.05). On the other hand, white blood cell count was found to be the lowest in groups of 2 steers with statistical significance at p<0.05. We conclude that a large rearing space improved growth performances, behavioral characteristics, and blood parameters in Hanwoo heifers and steers. In the future, this data could be used to improve the welfare of rearing Hanwoo cattle.

이 연구에서는 정소가 제거된 흰쥐에 비타민 E와 셀레늄(Selevit)을 5주간 투여 후 체중, 장기 무게, 혈액학적 그리고 생화학적 변화를 관찰하였다. 체중의 변화에서는 모든 실험군에서 증가가 나타냈다.

Intact군, Sham군, Orch군의 신장 무게는 Orch+Selevit군 비교 시 유의적인 증가를 확인하였다. 백혈구 수의 혈액학적 변화에서는 Orch+Selevit군은 다른 모든 군과 비교해 유의적인 증가를 확인하였으며, 적혈구수, 평균적혈구용적, 평균적혈구혈색소량, 평균적혈구색소농도 등과 같은 혈액학적 측정치에서는 유의성은 인정되지 않았다. 생화학적 변화에서는 Orch+Selevit군의 혈청총단백질, 알부민은 Orch군과 비교 시 유의적으로 증가하였으며, 알부민은 Intact군, Sham군 그리고 Orch군과 비교 시 유의적으로 감소했다. AST와 ALT는 모든 실험군에서 유의성이 없었다.

본 시험은 효소제 및 효모추출물 급여가 사양성적, in vitro 반추위 발효 및 혈액성상에 미치는 영향을 구명하기 위해 23개월령의 한우 거세우 48두를 공시하여 사료용 첨가제로 농후사료의 0.1% 수준으로 급여하여 출하시까지 대조구(무첨가), 처리구 1(효소제), 처리구 2(효모추출물), 처리구 3(효소제+효모추출물)으로 구분하여 급여하였다. 사양성적에서는 급여 4개월과 8개월의 일당증체량과 사료요구율이 처리구 1에서 가장 향상되었고 (p<0.05), 대조구에서 가장 낮았다(p<0.05). 도축성적에서는 육량지수를 포함하여 처리구 1>처리구 3>처리구 2>대조구 순으로 나타났다. in vitro 배양액에 따른 처리구별 pH는 대조구>처리구 2>처리구 3>처리구 1 순으로 유의적(p<0.05)인 차이를 나타냈고, VFA와 사료소화율은 처리구 1과 3에서 높았고 (p<0.05), 대조구에서는 낮았다(p<0.05). 혈액성상에서는 면역 첨가제 급여군인 처리구 2와 3에서 급여기간에 따른 백혈구 수치가 유의적(p<0.05)으로 감소하였는데, 이는 면역글로블린 G의 유의적(p<0.05)인증가에 따라서 상대적으로 나타난 것으로 판단된다. 결과적으로, 한우 비육후기 거세우의 사료첨가제 급여 시험에서 처리구 1은 급여 4개월부터 대조구 대비 사양성적 및 도체성적을 향상시켰고, 처리구 2는 급여 2개월부터 면역에 관련된 면역글로블린 G의 혈액성상을 개선시키는 것으로 분석되었다.

This study was conducted to investigate the effect of enzyme and yeast extract supplement on growth performance, carcass characteristics and blood parameters in Hanwoo steers. A total of forty-eight 23-month-old Hanwoo steers, with average initial body weight of 545.25±12.60 kg, were assigned to four treatments with three replicates in a completely randomized design. Hanwoo steers housed in four heads group per pen. The treatments comprised of four groups of control (no feed additives), treatment 1 (xylanase, cellulase, and gluco-amylase; 0.1%/concentrate), treatment 2 (β-glucan and mannan-oligosaccharide; 0.1%/concentrate), and treatment 3 (treatment 1+2; 0.1%/concentrate). During the fourth and eighth month, average daily gain and feed conversion rates improved in treatment 1, but in the control this was lower than the other treatments (p<0.05). Real-time ultrasound was used for measuring the live carcass traits (longissimus muscle area, back fat thickness, and marbling score) and the better results were in the following order: treatment 1 > treatment 3 > treatment 2 > control, and extended to carcass grade. White blood cell indices were lower in treatments 2 and 3 and the IgG indices were relatively higher than in other treatments. As a result, levels of xylanase, cellulase, and gluco-amylase were increased from the fourth month to improve growth performance, live carcass traits. Durin

This study was carried out to compared the characteristics of the underweight university students with those of overweight university students. The surey was carried out by self-questionnaires with 97 underweight and 156 overweight university students. The results are summarized as fellows. Breakfast was skipped in 37.1% of underweight and 46.2% of overweight students and it appeared overweight students eat faster than underweight students. The 16.5% of underweight and 75.0% of overweight students have correct perception about their body image. The percentage of weight control experience were 25.8and 55.8 in the underweight and overweight students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of underweight students were 96.41, 143.75, 97.53 and 56.27 mg/dl, and those of overweight students were 107.99, 164.31, 100.08 and 53.64 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels o( overweight students were higher than those of underweight students. On the other hand, plasma HDL cholesterol levels of overweight students were lower than those of underweight students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of overweight students were higher than that of underweight students. Therefore they should have a nutritional education program to improve their dietary and living habits for overweight students' health. And nutritional education program should be organized practically and systematically

A light-emitting diode (LED) is most efficient in terms of economic benefits. The aim of the present study was to evaluate the effects of LED lighting intensity on milk production, milk composition, and the immune response of Holstein cows. Thirty-eight lactating cows were assigned to four experimental groups: control group (exposed natural daylight without LED light) and three LED treatment group (50 lux; natural daylight and 6 h LED light of 50 lux intensity, 100 lux; natural daylight and 6 h LED light of 100 lux intensity, 200 lux; natural daylight and 6 h LED light of 200 lux intensity). There was a significant effect on the decrease ratio in milk production in 200 lux group. Lactose was significantly increased in 100 lux than the other LED treated groups. In addition to the hemolytic biochemical analysis, AST and β-HB were significantly increased in the 50 lux than the other groups. Prolactin and IGF-1 levels were significantly increased in 200 lux compared to other groups. Besides, cortisol was significantly higher in 50 lux and lowered in the 200 lux than the control, while IgA and IgG were not significant among the groups. Therefore, it was concluded that LED lighting intensity had some impact on blood parameters and immune responses in dairy cows with increased milk production.

Light is an essential and powerful element to animals. A light-emitting diode (LED) is most efficient in terms of economic benefits. The aim of the present study was to evaluate the effects of LED lighting time on milk production, milk composition, and the immune response of Holstein cows. Forty lactating cows were assigned to four experimental groups: control; natural daylight, treatment; am3-6, pm6-12 and pm6-am6. We found that there was no significant effect on the decrease ratio in milk production among the groups. Milk urea nitrogen (MUN) was significantly decreased in pm6-am6 and pm6-12 than the control. With regard to the hemolytic biochemical analysis, GLU was significantly increased and CRE, T-BIL were significantly decreased in the pm6-12 than the control. IGF-1 levels were significantly increased in pm6-12 compared to other groups. Besides, cortisol was significantly lowered in the pm6-12 than the control, while prolactin, IgA and IgG were not significant among the groups. In addition, catalase and glutathione peroxidase were also significantly increased in pm6-12 than the control. However, antioxidant enzyme activity and superoxide dismutase were not significant among the experimental groups. Therefore, it was concluded that LED lighting time had some impact on blood parameters and immune responses in dairy cows without any changes in milk production.
