In our study, osteoporosis was induced by ovariectomized in female Sprague-Daweley (SD) rats, and the prevention and treatment efficacy of the climacteric disease the ostmenopausal type I pattern was examined by using the experimental substance soybeans and arowroot. No clinical signs and mortality after continuous oral administration of experimental substances for 14 weeks were not observed, however, the weight of experimental animals underwent ovariectomized was increased significantly in comparison with control group (p<0.01). The atrophy of the uterus due to T3 group was 23.64% after 7 weeks, 24.44% after 14 weeks (in comparison with N.C. group), and it was statistically significantly increased. In regard to the change of blood cells, it was observed that platelets were statistically significantly reduced in the ovariectomized group, and administered orally experimental substances continuously for 7 weeks, in all groups administered experimental substances, it was found that platelets had the tendency to be increased more than N. C. group. In regard to He change of blood biochemistry, removed the ovary, the concentration of ALP showed the tendency to be increased than control group, and particularly in T3 group, it was increased significantly. In regard to the concentration of cholesterol, in comparison with negative control group, it was reduced 68% at 7 weeks and 35% at 14 weeks. After ovariectomized, the amount of estrogen was found to be reduced by 21.37% in comparison with control group, it showed the tendency to be increased by 4.49% in T1 group and 7.62% in T2 group, the concentration of estrogen in each group showed the tendency to be increased than negative control group, and in T3 group, it was increased to 100.46% and 117.65% in T4 group, and it was increased more than control group. Based on the above experimental results, in the experimental animals female rats, because of the hormonal imbalance induced by ovariectomized, a large mount of fat is accumulated in the body and due to it osteoporosis, obesity, hypertension, hyperlipidemia, fat of the liver, arteriosclerosis, diabetes, and other metabolic diseases were developed. Hence, when the experimental substance Extraction of ferment arrowroot was orally administered continuously for 14 weeks, it was thought that a certain proportion of the hormonal balance was maintained that functioned as a substance interfering the accumulation of fat, and it was considered to be of help in the treatment of not only osteoporosis Type I, but also for the prevention and treatment of various endocrinal diseases.

The present study was conducted to estimate energy requirements for maintenance in laying hens by using indirect calorimetry and energy balance. A total of 576 28-wk-old Nongda-3 laying hens with dwarf gene were randomly allocated into four ME intake levels (86.57, 124.45, 166.63 and 197.20 kcal/kg body weight $(BW)^{0.75}$ per d) with four replicates each. After a 4 d adaptation period, 36 hens from one replicate were maintained in one of the two respiration chambers to measure the heat production (HP) for 3 d during the feeding period and subsequent 3 d fast. Metabolizable energy (ME) intake was partitioned between heat increment (HI), HP associated with activity, fasting HP (FHP) and retained energy (RE). The equilibrium FHP may provide an estimate of NE requirements for maintenance (NEm). Results showed that HP, HI and RE in the fed state increased with ME intake level (p<0.05). Based on the regression of HP on ME intake, the estimated ME requirements for maintenance (MEm) was 113.09 kcal/kg $BW^{0.75}$ per d when ME intake equals HP. The FHP was decreased day by day with the lowest value on the third day of starvation. Except for lowest ME intake level, the FHP increased with ME intake level on the first day of starvation (p<0.05). The FHP at the two higher ME intake levels were greater than that at the two lower ME intake levels (p<0.05) but no difference was found between the two lower ME intake levels. Linear regression of HP from the fed state to zero ME intake yielded a value of 71.02 kcal/kg $BW^{0.75}$ per d, which is higher than the extrapolated FHP at zero ME intake (60.78, 65.23 and 62.14 kcal/kg $BW^{0.75}$ per d for the first, second and third day of fasting, respectively). Fasting time, lighting schedules, calculation methods and duration of adaptation of hens to changes in ME intake level should be properly established when using indirect calorimetry technique to estimate dietary NE content, MEm and NEm for laying hens.

The purpose of this study was to compare the nutrient intake and diet quality of postmenopausal osteoporotic women to those of control subjects, and to investigate the relationship among diet quality and bone mineral density in postmenopausal women. In this study, we classified the subjects into the postmenopausal osteoporotic women (n =38) and control (n = 43) according to their lumbar spine bone mineral density and age. Dietary intakes, anthropometric measurements and dietary quality indices were measured and evaluated. The average age of osteoporotic and control group were 60.4 yrs and 58.3 yrs, respectively and there was no significant difference. Body weight, body mass index of osteoporotic group were significantly lower than those of control group. The average energy intake of osteoporotic and control group were 1243.3 kcal and 1475.8 kcal, respectively and there was a significant difference. The osteoporotic group consumed significantly lower quantities of protein, plant protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, animal calcium, plant calcium, iron and zinc compared to the control group. The osteoporotic group consumed significantly lower of food, vegetables, mushrooms, fruits intakes compared to the control group. In the diet quality, protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, iron, Zinc nutrient adequacy ratio (NAR) of osteoporotic group were significantly lower than that of control group. Mean adequacy ratio (MAR) of osteoporotic and control group were 0.63 and 0.78, respectively and there was significant difference. To evaluate nutrient density, Index of nutritional quality (INQ) was calculated by dividing nutrient content per 1,000 kcal of diet with RDA per 1,000 kcal. The average dietary variety score (DVS) of osteoporotic and control group were 22.4 and 33.2, respectively and there was significant difference. DVSs of pulses (p<0.01), seeds (p<0.01) and vegetables (p<0.05) in osteoporotic group were significantly lower than those of the control. In conclusion, postmenopausal osteoporotic women had lower protein, vitamin A, folate, vitamin C, calcium, iron zinc intake quality and vegetables, mushrooms, fruits DVSs than those of the control. Therefore, to promote skeletal health enough energy and food should be consumed, and the maintenance of vitamin and mineral balance by increasing of vitamin A, folate, vitamin C, calcium, iron of intakes are very important.

Four young swamp buffalo cows of similar age ranging in body weight (W) between 280 to 380 kg and trained for doing physical exercise were used in two consecutive experiments, each using a latin square design, to determine energy expenditure for draught. The experiments consisted of field trials using 4 levels of work load, i.e. no work as control and loads amounting 450 to 500 Newton (N) continuous traction for respectively 1, 2 and 3 h daily for 14 consecutive days for experiment 1, and no work, traction loads equaling 5, 10 and 15% of W for 3 h daily for 14 days for experiment 2. Heart rate during rest and exercise was monitored using PE-3000 HR monitor. Cows were fed only king grass (Penisetum purpuroides) ad libitum and were subjected to balance trials. Body composition was estimated in vivo by the body density method and daily energy expenditure (EE) was calculated from ME minus RE. RE was calculated from the changes in body-protein and -fat measured before and immediately after the 14 d experimental period assuming an energy equivalent of 39.32 MJ/kg fat and 20.07 MJ/kg protein. $E_{exercise}$ ($EE_{work}\;-\;EE_{resting}$), which was the energy spent for doing the traction during 1, 2 and 3 h was 7.13, 15.45 and 19.90 MJ, respectively. $EE_{work}$ for the 1 h treatment group was 39.75 MJ/d equivalent to 1.30 times $EE_{resting}$. The values for the 2 and 3 h treatment groups were 1.75 and 1.86 times resting energy requirement, respectively. Absolute efficiency of work in all exercise trials of experiment 2 was around 27.28%. The increases of daily $E_{exercise}$ values were correlated to elevation of heart rate (HR) according to the equation $E_{exercise}=(0.270HR^{0.363}\;-\;1)$ MJ, while draught force related to heart rate according to the equation DF (N)=6.66 HR - 361.62. Blood glucose and triglyceride levels were gradually elevated with time during the course of exercise. Mean values of blood glucose were 91.7, 115.0 and 116.2 mg/dl for cows after 1, 2 and 3 h pulling loads at 15% W respectively as compared to 88.2 mg/dl prior to work. In the same order and treatment, mean blood triglyceride concentrations were 13.5, 13.3 and 14.8 mg/dl, and 11.5 mg/dl for control. For blood lactate, the values were 1.68, 1.63 and 1.66 mM, and 0.80 mM for control. Glucose was used as the major source of energy during the initial phase of exercise, but for prolonged work, fat will replace carbohydrate as the main substrate. Accumulation of lactate persisted for some time at the end of the exercise trials.

Objective: This study investigated the effect of dietary crude protein (CP) supplementation on nutrient intake, nitrogen (N) utilisation, blood metabolites, ruminal fermentation and growth performance of young Holstein bulls. Methods: Twenty-one young bulls weighing $277{\pm}11.2kg$ were equally divided into three groups and were offered diets formulated with low CP (LCP; 10.21% CP and 4.22% rumen degradable protein [RDP]), medium CP (MCP; 12.35% CP and 5.17% RDP) and high CP (HCP; 14.24% CP and 6.03% RDP). Yellow corn silage was used as a unique forage source and was mixed with concentrate. This mixed feed was given ad libitum to the young bulls included in the study. Results: Results showed that CP intake, blood urea nitrogen, N intake, total N excretion and N balance increased linearly with an increase in dietary CP level (p<0.05). However, no significant difference was observed in nutrient digestibility among the bulls receiving the different diets. Ruminal pH (p<0.05) and ammonia nitrogen ($NH_3-N$) concentration (p<0.01) were significantly higher in the bulls receiving the MCP and HCP diets than in those receiving the LCP diet. The bulls receiving the HCP diet showed significantly higher ruminal bacterial protein level, propionate, acetate and total volatile fatty acid (TVFA) concentrations than bulls receiving the LCP diet (p<0.05). Moreover, dietary CP level exerted a significant positive effect on the final body weight, average daily gain and gain-to-feed ratio of the bulls (p<0.05). Conclusion: High dietary CP level is optimal for achieving maximum growth and high profitability without exerting a negative effect on the physiology of growing Holstein bulls.

본 연구는 언론보도에 의한 초상권 침해 관련 판결의 추이와 승패 여부, 원인 등 초상권 침해를 둘러싼 언론소송 특성을 고찰하기 위한 것으로 최종심 판결이 처음 나오기 시작한 1990년부터 2014년까지 언론보도에 의한 초상권 침해 관련 판결 81건을 전부 수집해 판결문을 분석했다. 분석결과 언론을 상대로 제기된 초상권 침해 관련 소송의 최종심 재판 결과가 처음 나온 것은 1990년이다. 1990년대에는 주로 선정적 보도가 많았던 월간잡지를 대상으로 하는 초상권 분쟁이 많았으나 2000년대 들어서는 방송을 대상으로 한 초상권 침해분쟁이 크게 늘어났다. 2000년 이후에는 초상권 관련 언론소송의 71% 가량이 방송에 집중됐다. 방송의 영향력이 커진데다 영상을 필수로 하는 방송의 특성상 초상권 침해 소지가 높았기 때문이다. 특히 2005년 "언론중재법"이 시행된 후 초상권 관련 소송이 급격히 늘어난 것은 주목할 만한 현상이다. 초상권 관련 언론소송 81건 가운데 언론사가 승소한 사건은 23건으로 언론사 승소비율은 28. 4%에 그쳤다. 이는 법원이 언론매체의 특수성을 고려하기보다는 일반인의 초상권 보호를 우선으로 고려한 결과로 분석된다. 하지만 원고가 공인인 경우 언론사 승소율이 52. 9%에 달해 일반인 경우의 언론 승소율 22%보다 월등히 높아 언론사를 상대한 초상권 소송에서 공인이 일반인에 비해서 불리했던 것으로 나타났다. 이는 1997년 이후 활발하게 논의되기 시작한 공인 이론의 적용으로 공인에 대한 언론의 감시기능을 법원이 인정한 것으로 볼 수 있다.

A digestibility study was conducted to evaluate the effects of supplementing mulberry foliage and urea rice-bran as a source of fermentable energy and protein to 12 sheep fed diets based on urea-treated rice straw (TRS). The three dietary treatments were: T1, TRS with mulberry; T2, TRS with 50% mulberry replaced with rice bran and urea; and T3, TRS with rice bran and urea. The study was arranged in a completely randomized design with four replications for each treatment. The sheep were fed one of the three diets and the supplements were offered at 1.2% of the body weight (BW) and the TRS was provided ad libitum. There were no differences (p>0.05) among the three treatment groups with respect to dry matter (DM) intake ($76.8{\pm}4.2g/kg\;BW^{0.75}$) and DM, organic matter (OM), and crude protein (CP) digestibility ($55.3{\pm}1.22$; $69.9{\pm}0.85$; $46.3{\pm}1.65%$ respectively for DM, OM, and CP). The digestibility of fiber (neutral detergent fiber [NDF] and acid detergent fiber) was significantly lower (p<0.05) for T3 (46.2 and 46.6 respectively) compared to T1 (55.8 and 53.7 respectively) and T2 (54.1 and 52.8 respectively). Nitrogen (N) intake by sheep on diet T3 was significantly (p<0.05) higher than sheep fed diet T1. However, N balance did not differ among the three diets ($3.0{\pm}0.32g/d$). In contrast, the rumen ammonia ($NH_3-N$) concentrations in sheep fed T2 and T3 were significantly (p<0.05) higher than in sheep fed T1. The $NH_3-N$ concentrations for all three diets were above the critical value required for optimum rumen microbial growth and synthesis. Total volatile fatty acid concentrations were highest (p<0.05) in T1 (120.3 mM), whilst the molar proportion of propionic acid was highest in T3 (36.9%). However, the microbial N supply in sheep fed T1 and T3 was similar but was significantly (p<0.05) higher than for sheep fed T2. It was concluded that mulberry foliage is a potential supplement of fermentable energy and protein for sheep fed TRS based diet. The suggested level of supplementation is 1.2% of BW or 32% of the total diet since it resulted in similar effects on the intake of DM, OM, and NDF, digestibility of DM, OM, and CP, N utilization and microbial supply when compared to rice bran and urea supplementation.

Objective: This study aimed to assess the effect of pelleted and expanded sorghum-based feeds prepared with different moisture levels and particle size of ingredients on metabolizable energy, ileal digestibility of amino acids and broiler performance. Methods: The experiment was performed with 720 male broiler chicks of the Cobb strain, with treatments of six replications, with 15 birds each; they were arranged in a completely randomized design and $2{\times}2{\times}2$ factorial scheme (pelleted or expanded feed processing, 0.8% or 1.6% moisture addition in the mixer, and particle size of 650 or 850 microns). Results: Higher pellet quality (pellets, % and pellet durability index [PDI]) was obtained in expanded diets and inclusion of 1.6% moisture. The particle size of 850 microns increased the PDI of final diet. All studied treatments had no significant effect on weight gain and broiler carcass and cut yields. Lower feed conversion occurred for birds fed pelleted feed at 42 d. The highest apparent metabolizable energy (AME) and apparent metabolizable energy corrected to zero nitrogen balance (AMEn) values of feed in the initial rearing phase (10 to 13 days) were observed in birds fed pelleted feed or for feed prepared with 1.6% moisture. The highest ileal digestibility coefficients of amino acids were obtained with the consumption of pelleted feed prepared with a particle size of 650 microns and 1.6% moisture. Conclusion: Pelleted feed prepared with a milling particle size of 650 microns and 1.6% moisture provided increased ileal digestibility of amino acids and AMEn in the starter period. However, the expanded feed improved pellet quality and feed conversion of broilers at 42 days of age. We conclude that factors such as moisture, particle size and processing affect the pellet quality, and therefore should be considered when attempting to optimize broiler performance.

본 연구는 NaCl 및 jasmonic acid(JA) 처리 시 스피아민트(Mentha spicata)의 생육 및 생리적 반응 변화를 조사하고자 실시하였다. 대조구, JA($20{\mu}M$ JA 전처리), JA+NaCl($20{\mu}M$ JA 전처리+ 50mM NaCl), NaCl(50mM NaCl) 처리 등 4처리구로 구분하여 0.5배 Hoagland 용액에서 3주간 수경 재배한 후 생장반응과 엽록소, 비타민 C, 프롤린, 무기물, DPPH 라디칼 소거 항산화 활성 등을 측정하였다. 스피아민트의 초장, 엽장, 엽폭 및 생체중은 대조구에 비해 모든 처리구에서 감소하였고, 특히 NaCl 처리구에서 현저히 감소하였다. 반면에 건물중은 JA+NaCl 혼용처리구를 비롯하여 모든 처리구에서 증가하였다. 엽록소 a와 b 함량은 JA 처리구가 가장 높았으나 비타민 C와 항산화 활성 및 지상부의 프롤린 함량은 염 스트레스로 생육이 가장 낮았던 NaCl 처리구에서 가장 높게 나타났다. 이온 흡수의 균형 정도를 알 수 있는 K/Na 비율은 JA 단독 처리 시 증가하였고, NaCl처리 및 JA+NaCl 혼용 처리구에서는 $Na^+$ 흡수 증가로 인하여 K/Na 비율이 낮아졌다. 이러한 결과는 낮은 염 스트레스나 JA처리 같은 적절한 스트레스 처리가 항산화 활성과 정유를 포함하는 이차대사물질의 축적을 유도함으로써 스피아민트의 품질을 향상시킬 잠재적인 가능성을 보여준다.

Two experiments were conducted to evaluate the effects of a complex Lactobacilli preparation on performance, resistance to E. coli infection and gut microbial flora of weaning pigs. In exp. 1, twelve pigs (7.65$\pm$1.10 kg BW), weaned at 28 d, were randomly allotted into 2 groups and placed in individual metabolic cages. During the first 7 d, one group of pigs was provided ad libitum access to water containing $10^5$ colony forming units (CFU) Lactobacilli per ml and the control group was provided tap water. The Lactobacilli preparation included Lactobacillus gasseri, L. reuteri, L. acidophilus and L. fermentum, which were isolated from the gastrointestinal (GI) tract mucosa of weaning pigs. On d 8, 20 ml of $10^8$ CFU/ml E. coli solution (serovars K99, K88 and 987P at the ratio of 1:1:1) was orally administered to each pig. Diarrhea scores and diarrhea incidence were recorded from d 7 to 14. On d 14, pigs were euthanized and digesta and mucosa from the stomach, duodenum, jejunum, ileum, cecum and colon were sampled using aseptic technique to determine microflora by culturing bacteria in selective medium. The results showed that Lactobacilli treatment significantly decreased E. coli and aerobe counts (p<0.01) but increased Lactobacilli and anaerobe counts (p<0.01) in digesta and mucosa of most sections of the GI tract. A 66 and 69.1% decrease in diarrhea index and diarrhea incidence, respectively, was observed in the Lactobacilli treated group. In exp. 2, Thirty-six crossbred Duroc$\times$Landrace$\times$Yorkshire piglets, weaned at 28$\pm$2 days, were selected and randomly allocated into 2 groups. There were 18 piglets in each group, 3 piglets in one pen and 6 replicates in each treatment with 3 pens of barrow and 3 pens of female piglet in each treatment. Piglets had ad libitum access to feed and water. The initial body weight of piglet was 7.65$\pm$1.09 kg. Dietary treatments included a non-medicated basal diet with Lactobacilli ($10^5$ CFU/g diet) or carbadox (60 mg/kg) as control. On d 21, six pigs per group (one pig per pen) were euthanized. Ileal digesta was collected to determine apparent amino acid digestibility. Microflora content was determined similarly to exp.1. The results showed that Lactobacilli treatment significantly improved average daily feed intake (ADFI) of pigs compared to carbadox (p<0.05) during the first 2 wks after weaning and average daily gain (ADG) and ADFI increased significantly (p<0.05) from d 8 to 14. Nitrogen and total phosphorus digestibility also increased (p<0.05). Bacterial counts were similar to exp. 1. The results indicate that the complex Lactobacilli preparation improved performance for 2 wks after weaning, enhanced resistance to E. coli infection, and improved microbial balance in the GI tract.
