  • Napier grass (Pennisetum purpureum Schum.) harvested at an early growth stage was ensiled with 4% of molasses in a polyethylene bag silo which contained 15 kg of chopped forage each. Dry matter (DM) content of the silage was so low as 14.75%, although chemical quality of the silage was very high. Ratio of ammonia nitrogen to total nitrogen was 6.59%, and the pH value of the silage was 3.79. Nutritive value of the silage was estimated using goats and compared to that of a timothy hay as a reference ration. Feeding level of each rations was adjusted to a level of nitrogen (N) recommendation. DM and N digestibilities of the silage were 65.0 and 54.5%, respectively, but those of the timothy hay were 37.6 and 37.2%. Feeding of the napier grass silage maintained body weight and kept positive N retention. Ammonia N concentration in the rumen fluid in goats fed the napier grass silage increased after feeding, but blood urea concentration was constant. Feeding of the timothy hay did not increase ammonia N concentration in the rumen fluid, but increased blood urea concentration. These facts indicated that the napier grass silage had enough digestible DM and N for maintenance ration to goats.

  • This study measured each daily intake and excretion of iron copper and cobalt of eight 20-26 years old college men during four weeks by means of analyzing their food intake urine and feces keeping their normal living pattern and maintenance body weight. This study also compared the actual measurement value of iron intake by atomic absorption spectrophoto-meter with the conversion value of it by food table. The results were as follows. Each person's average intake daily was iron 9.19±0.32mg/day, copper 0.56±0.06mg/day and cobalt 1.86±0.18mg/day. Each person's average urinary excretion daily was iron 0.53±0.07mg/day, copper 0.07±0.03mg/day and cobalt 0.13±0.01mg/day. Each person's average fecal excretion daily was iron 1.73±0.14mg/day copper 0.16±0.01mg/day and cobalt 0.46±0.08mg/day. The actual measurement value was 9.19±0.32mg/day and its conversion value 14.07±0.29mg/day : the former was 35% lower than the latter.

  • Nutritional assessment and support are often overlooked in the critically ill due to other urgent priorities. Unlike oxygenation, organ dysfunction, infection, or consciousness, there is no consensus of indicators. Making it difficult to evaluate the effectiveness of an intervention. Nevertheless, appropriate nutritional support in the critically ill has been associated with less morbidity and lower mortality. But, nutritional support has been considered an adjunct, for body weight maintenance and to help patients during the inflammatory phase of illness. Thus, it has been assigned a lower priority, compared to mechanical ventilation or hemodynamic stability. Recent findings have shown that nutritional support may prevent cellular injury due to oxidative stress and help strengthen the immune response. Large-scale randomized trials and clinical guidelines have shown a shift from nutritional support to nutritional therapy, with an emphasis on the importance of protein, minerals, vitamins, and trace elements. Nutrition is also important in neurocritically ill patients. Since there are few studies or recommendations with regard to the neurocritical population, the general recommendations for nutritional support should be applied.

  • Taurine is one of the most abundant free ${\beta}$-amino acids in the human body that accounts for 0.1% of the human body weight. It has a sulfonic acid group in place of the more common carboxylic acid group. Mollusks and meat are the major dietary source of taurine, and mother's milks also include high levels of this amino acid. The leukocytes, heart, muscle, retina, kidney, bone, and brain contain more taurine than other organs. Furthermore, taurine can be synthesized in the brain and liver from cysteine. There are no side effects of excessive taurine intake in humans; however, in case of taurine deficiency, retinal abnormalities, reduced plasma taurine concentration, and other abnormalities may occur. Taurine enters the cell via a cell membrane receptor. It is excreted in the urine (approximately 95%) and feces (approximately 5%). Taurine has a number of features and functions, including conjugation with bile acid, reduction of blood cholesterol and triglyceride levels, promotion of neuron cell differentiation and growth, antioxidant effects, maintenance of cell membrane stability, retinal development, energy generation, depressant effects, regulation of calcium level, muscle contraction and relaxation, bone formation, anti-inflammatory effects, anti-cancer and anti-atherogenic effects, and osmotic pressure control. However, the properties, functions, and effects of taurine require further studies in future.

  • The purpose of this study was to investigate efficient treatment in obesity. In order to help clinical application in obesity treatment, this study was performed to investigate the cause and treatment in obesity. The main finding of this study were as follows. 1. In the cause of oriental medicine in obesity, that were moisture(濕), phlegm(痰), gore(瘀), the productive heat(積熱), overeating, supemutrition, underaction, heredity and habitude, psychologic factor(stress) etc. 2. In the western medicine, the cause of obesity were genetic cause, endocrine disorder, hypothalamic extraodinary and secondary effect of drug. But simple obesity is the greater part. Also there were psychologicai and environmental causes. 3. Ear acupuncture of wide application were Naebunbi, Sinmun, Taejang, $ij{\check{o}}m$, $Pyej{\check{o}}m$, $Bij{\check{o}}m$ etc. 4. Body acupuncture of application were $Naej{\check{o}}ng$, $Sangg{\check{o}}h{\check{o}}$, Pungnyung, Kokchi, $Sam{\check{o}}mgyo$, $Umn{\check{o}}ngch{\check{o}}n$ etc. 5. In oriental medical treatment of obesity, Bangpungtongs ngsan(防風通聖散), Daesihotang(大柴胡湯), Seungkitang(承氣湯), Bangkihwangkitang(防己黃?湯), Richulsaryeungtang(二朮四笭湯), Taeksatang(澤瀉湯), Opieum(五皮飮), Gongyundan(控涎丹) etc were wide applicated. 6. The western medical treatment in obesity encourage the dietary cure, exercise cure and behavior adjustment than medical therapy or operation. In treatment of obesity, the dietary cure and herb-drug therapy, ear acupuncture and body acupuncture are effective. But weight maintenance after treating is more important. After all the continuous dietary cure, behavior adjusting cure and exercise cure are necessary.

  • BACKGROUND/OBJECTIVES: Aging is an imperative problem for many countries in this century, and presents several challenges for the maintenance of good nutritional status. This study aims to assess the impact of socio-demographic factors, lifestyle and health status on the nutritional status among the elderly in Taiwan. SUBJECTS/METHODS: A cross-sectional study was carried out in Taiwan. Data were obtained from the Mei Jau Health Management Institution, which is a private health evaluation provider with multiple health screening centers in Taiwan and Asia. This study included 7947 adults aged 65 years or above. The data were extracted between 2001 to 2010. Nutritional status was assessed using anthropometric data, biochemical data and dietary intake information. RESULTS: Among the 7947 participants with mean age of 70.1 (SD = 4.5) years, 20.2%, 6.6%, 10.5% and 52.5% experienced underweight, protein malnutrition, anemia and inadequate dietary intake in the past month, respectively. Age was negatively correlated with body weight (r = -0.19, P = 0.02), body mass index (r = -0.41, P < 0.001), albumin level (r = -0.93, P < 0.001) and hemoglobin level (r = -0.30, P = 0.008). Age above 70 years, gender, unmarried status, retirement, lack of education, low family income, smoking, alcohol drinking, sleep duration of 6-8 hours, vegetarian diet, multiple medications, comorbidity and dysphagia were positively associated with malnutrition in older adults. CONCLUSIONS: Underweight and inadequate dietary intake are prevalent among the elderly in Taiwan. Vegetarian diet, multiple medications, comorbidity, dysphagia and lifestyle factors such as smoking, alcohol drinking and sleep duration of 6-8 hours are risk factors for undernutrition in older adults.

  • Objective: This study was conducted to assess the effects of replacing rice straw with different proportions of cassava pulp on growth performance, feed intake, digestibility, rumen microbial population, energy partitioning and efficiency of metabolizable energy utilization in beef cattle. Methods: Eighteen yearling Thai native beef cattle (Bos indicus) with an average initial body weight (BW) of $98.3{\pm}12.8kg$ were allocated to one of three dietary treatments and fed ad libitum for 149 days in a randomized complete block design. Three dietary treatments using different proportions of cassava pulp (100, 300, and 500 g/kg dry matter basis) instead of rice straw as a base in a fermented total mixed ration were applied. Animals were placed in a metabolic pen equipped with a ventilated head box respiration system to determine total digestibility and energy balance. Results: The average daily weight gain, digestible intake and apparent digestibility of dry matter, organic matter and non-fiber carbohydrate, total protozoa, energy intake, energy retention and energy efficiency increased linearly (p<0.05) with an increasing proportion of cassava pulp in the diet, whereas the three main types of fibrolytic bacteria and energy excretion in the urine (p<0.05) decreased. The metabolizable energy requirement for the maintenance of yearling Thai native cattle, determined by a linear regression analysis, was $399kJ/kg\;BW^{0.75}$, with an efficiency of metabolizable energy utilization for growth of 0.86. Conclusion: Our results demonstrated that increasing the proportion of cassava pulp up to 500 g/kg of dry matter as a base in a fermented total mixed ration is an effective strategy for improving productivity in zebu cattle.

  • This study was conducted to predict the energy requirements for maintenance and growth of female Korean black goats during their growth and pregnancy phases. Fifty female goats ($18.7{\pm}0.27kg$) in their growth phase with an average age of 5 months were stratified by weight and randomly assigned into 5 groups. They were fed 5 diets varying in metabolic energy (ME) [2.32 (G1), 2.49 (G2), 2.74 (G3), 2.99 (G4), and 3.24 (G5) Mcal/kg] until they were 9-month-old. After natural breeding, 50 female goats ($30.7{\pm}0.59kg$) were stratified by weight and randomly assigned into 5 groups. They were fed 5 diets varying in ME [2.32 (P1), 2.43 (P2), 2.55 (P3), 2.66 (P4), and 2.78 (P5) Mcal/kg]. The average feed intake ranged between 1.5 and 2.0% of the body weight (BW), and there was no significant difference between the treatment groups with goats in growth or pregnancy phases. Average daily gain (ADG) in diet demand during the growth phase increased with an increasing ME density and ranged from 46 to 69 g/d (p<0.01). Feed conversion ratio (FCR) improved with the ME density during the growth phase (p<0.01). The intercept of the regression equation between ME intake and ADG indicated that energy requirement for maintenance of goats during growth and pregnancy phases was $103.53kcal/BW^{0.75}$ and $102.7kcal/BW^{0.75}$, respectively. These results may serve as a basis for the establishment of goat feeding standards in Korea. Further studies are required to assess the nutrient requirement of goats using various methods for improving accuracy.

  • This study compared the growth performance and carcass evaluation of Jeju native cattle (JNC) and its crossbreds (CBK = 25 JNC:50 Charolais:25 Brahman and BCBK = 62.5 JNC:25 Charolais:12.5 Brahman). Eight male calves of each JNC, CBK and BCBK were weaned at 4 month of age and were fed for 24 months of age. All animals grazed a pasture between 5 to 10 months of age then they were fed growing ration at the rate of 1.5% of their BW along with ad libitum supply of Italian ryegrass hay between 11 to 16 months of age and thereafter switched to ad libitum feeding of finishing ration and hay between 17 to 24 months of age. Mean body weight (BW) and BW gain were higher in CBK compared with BCBK and JNC at 4, 10, 16 and 24 months of age. Average daily BW gain during 4 to 10 months of age was the highest for CBK followed by BCBK and JNC. However, daily BW gain was higher in BCBK than in CBK and JNC during 11 and 16 months of age. During fattening period (17 to 24 months) average daily BW gain was higher in JNC than in CBK and BCBK. Slaughter weight, hot and cold carcass weight were higher in CBK compared with JNC and BCBK. Weight of bones, boneless meat, ribs, excluded rib meat, retailed cut meat, tender loin, sir loin, strip loin, sticking, top round, bottom round, fore leg, shank, and thin-flank were higher in CBK than in BCBK and JNC. Fat weight in these carcass cuts and kidney fat was similar in JNC and its crossbreds. Logissimus dorsi and its ratio were higher in CBK compared with BCBK and JNC. Percent moisture, crude protein, and ash contents of beef were similar in JNC and its crossbreds. Percent beef fat was higher in JNC and BCBK than in CBK. Cooking loss and water holding capacity of beef was similar in JNC and its crossbreds. Sheer force was lower in BCBK compared with JNC and CBK. Juiciness, tenderness and flavor of beef were higher in BCBK compared with JNC and CBK. In conclusion, CBK has shown higher growth rate and produced heavier carcasses with good degree of fatness compared with JNC and BCBK. However, fattening for longer period could increase the maintenance cost in CBK and BCBK because of their higher BW which they attained during growing period.

  • These experiments were conducted to investigate the effects of different feeding and processing methods of diets on performance, morphological changes in the small intestine and nutrient digestibility of growing-finishing pigs. One-hundred fifty growing pigs ($Yorkshire{\times}Landrace{\times}Duroc$; initial body weight of $23.33{\pm}0.75kg$) and one-hundred twenty finishing pigs ($Yorkshire{\times}Landrace{\times}Duroc$; initial body weight of $59.22{\pm}0.56kg$) were used in Exp. 1 and Exp. 2, respectively. Pigs were grouped on the basis of body weight and gender, and randomly allotted into 6 different treatments with 5 replications in each treatment in a $2{\times}3$ factorial arrangement. Treatments were 1) dry feeding with a mash diet (DM), 2) dry feeding with a pelleted diet (DP), 3) dry feeding with an expanded crumble diet (DEC), 4) dry/wet feeding with a mash diet (WM), 5) dry/wet feeding with a pelleted diet (WP), and 6) dry/wet feeding with an expanded crumble diet (WEC). In Exp. 1 (growing phase), there was no significant difference in average daily gain (ADG) and average daily feed intake (ADFI) among treatments during the entire experimental period, but feed conversion ratio (FCR) was significantly (p<0.05) improved in pigs fed pelleted diets regardless of feeding method. FCR was best in pigs fed a DP diet and worst in pigs fed a WM diet. Pigs fed a pelleted diet showed a 6.2% or 4.0% improvement in FCR compared with those fed a mash diet or an expanded crumble diet. Water disappearance was not significantly affected by dry/wet feeding or feed processing. Significant differences in villus height were not found among treatments, but villus height tended to be improved by dry/wet feeding. Dry/wet feeding or feed processing did not affect crypt depth. Digestibilities of calcium and phosphorus were significantly (p<0.05) improved in pigs fed an expanded crumble diet compared with pigs fed mash diets. Especially, pigs fed a WEC diet digested 8.1% more P than those fed a DM diet. Feed cost per kg weight gain (FCG) tended to be increased by dry/wet feeding rather than dry feeding. In Exp. 2 (finishing phase), ADG and ADFI were not significantly different among treatments, but a significant difference in FCR was found among feed processing forms. The best FCR was obtained in pigs fed a pelleted diet. Pigs fed a DP diet showed a 11.3% improvement compared with those fed a DEC diet. Water disappearance was significantly (p=0.0408) decreased by feeding the mash diet. However, water disappearance was not affected by dry/wet feeding during the finishing period. The villus height and crypt depth were not significantly different among treatments. However, crypt depth tended to be decreased by dry/wet feeding at the mid part of the small intestine. Fat digestibility was improved by dry feeding rather than dry/wet feeding, and was improved by 4.8% by feeding pellet diets compared with expanded crumble diets. Except for carcass grade, carcass characteristics were not significantly (p<0.05) different among treatments. Carcass grade was the best in pigs fed a WP diet. Feed cost per kg weight gain (FCG) was significantly decreased in pigs fed a pelleted diet compared with those fed an expanded crumble diet, and tended to be decreased by dry/wet feeding. In conclusion, these studies suggest that feeding the pelleted diet to growing-finishing pigs can be beneficial in terms of FCR and production cost. Dry/wet feeding can be helpful for the maintenance of villus height, but may not be reflected in improved growth performance or reduction of production costs.
