This study was carried out to investigate the effects of the inoculated diet with Paecilomyces japonica on weight gain, feed efficiency and cordycepin contents in the breast and thigh meats of broilers. One hundred and twenty broiler chicks were divided into four dietary groups ; 1) control (basal diet), 2) T1 (substituted with 5% inoculated diet), 3) T2 (substituted with 10% inoculated diet) 4) T3 (substituted with 20% inoculated diet) during 4 weeks. Cordycepin contents of inoculated diet with Pacilomyces japonica was significantly higher than before inoculation (P<0.05). Body weight gain and feed efficiency were highest in T1 group when fed starter diet (P<0.05) but these were lowest in T3 group fed when fed finished diet (P<0.05). Body weight gain and feed efficiency were the lowest in T2 group for overall period than other groups. Cordycepin contents of breast and thigh meats were significantly higher in Pacilomyces japonica groups than control at 5 weeks of age (P<0.05). However, it was similar among the T1, T2 and T3 groups. These results indicated that body weight gain and feed efficiency tended to increase in birds fed replaced 5% inoculation diet Cordycepin contents of breast and thigh meats would be increased significantly in birds fed inoculated diet (P<0.05).

BACKGROUND/OBJECTIVES: Relocation to new environments can have a negative impact on health by altering body weight and dietary patterns. This study attempted to elucidate changes in body weight, food security, and their current food and nutrient consumption in adult North Korean refugees (NKR) living in South Korea (SK). SUBJECTS/METHODS: This study analyzed data on 149 adult NKR from a North Korean refugee health in SK cohort at four time points (leaving North Korea, entering SK, first examination, and second examination). Body weight was self-reported at the two earlier time points and directly measured at the two later time points. Food security, diet-related behaviors (dietary habits and food consumption), and sociodemographic information were obtained using a self-administered questionnaire. Nutrient intake information was obtained by one-day 24-hour recall. Statistical analyses were performed with SPSS ver 23.0. RESULTS: Body weight increased during relocation by an average of 4 kg, although diversified patterns were observed during the settlement period in SK. Approximately 39.6% of subjects maintained their body weight between the first and second examinations, whereas 38.6% gained and 22.1% lost at least 3% of their body weight at the first examination by the second examination. Food security status improved from 12.1% food secure proportion to 61.7%. NKR showed generally good food and nutrient consumption (index of nutrient quality: 0.77-1.93). The body weight loss group showed the most irregular meal consumption pattern (P < 0.05), and eating-out was infrequent in all three groups. Consumption frequencies of food groups did not differ by group, except in the fish group (P = 0.036). CONCLUSION: This study observed considerable body weight adjustment during the settlement period in SK after initial weight gain, whereas food security consistently improved. More detailed understanding of this process is needed to assist healthy settlement for NKR in SK.

Acute (24 h) and chronic (90 days) oral toxicity studies on the ethanol extract of Trigonella foenumgraecum Leguminosae (L.) seeds were carried out. Acute dosages were 0.5, 1.0 and 3 g/kg while chronic dosage was 100 mg/kg per day of the extract. All morphological, biochemical, haematological and spermatogenic changes, in addition to mortality, body weight changes and any change in vital organs were recorded. Histopathological investigations were done on vital organs. Growth arrest in the treated animals was observed. The treated mice gained no significant weight during chronic treatment while there was a significant gain in body weight of the control group mice. Biochemical studies revealed a significant decrease in blood sugar levels of fenugreek treatment groups while haematological parameters remained comparable to the control. In the treatment, male group there was a significant decrease in weight of testes as compared to the control. There was a marginal weight gain in kidney weight of mice after chronic treatment as compared to the control. Fenugreek chronic treatment caused a highly significant spermatotoxic effects in male mice.

This study investigated the effect of adding poultry litter additive containing probiotics and amino acids to the litter on weight gain in ducks and ammonia content in poultry litter. Nine hundred 1-day-old ducks (Pekin) were randomly distributed into three groups (300 birds per treatment divided into three replicates) using a randomized block design. Treatments were top-dressed on the litter surface at rates of 2 kg poultry litter additives (T1) and 2 kg macsumsuk (T2) per m², and untreated poultry litter was used as the control. Overall, a significant difference (p<0.05) in weight gains was observed at 3 and 4 weeks, but not at 5 and 6 weeks. After 4 weeks, when compared to other treatments, the addition of poultry litter additive tended to increase the average body weight gain (90-130 g). The ammonia content was affected by all treatments (p<0.05) over time except at 3 weeks, however, compared to other treatments, the poultry litter additive decreased the ammonia content. In particular, the rate of ammonia reduction by the poultry litter additives over time was approximately 20.2%-49.2%. Regarding temperature, a significant difference was observed in all treatment groups (p<0.05), except at 3 weeks. In conclusion, considering poultry litter additives and temperature, the increase in duck weight gain was associated with a decrease in ammonia content in the poultry litter.

Three groups of 7, 8 and 8 barrows (22 weeks age; 35 kg body weight), reared on grower diets were fed ad libitum on three isonitrogenous finisher diets containing 50, 71 and 92% wheat bran by replacing maize grain till the attainment of about 74 kg slaughter weight. Growth pattern, average daily gain, feed intake, feed/gain ratio and carcass traits were similar in all the groups. The digestibility of DM, OM, CF, NFE total carbohydrate and energy (DE) decreased (p<0.01) with the increased level of wheat bran in the diet. However, CP digestibility was comparable among all the diet and the digestibility of EE was significantly (p<0.01) higher in grainless diet ($FD_3$). It appears that maize grain may be completely replaced with wheat bran in the diet of crossbred pigs without any adverse effect on their performance with respect to feed intake, body weight gain and carcass characteristics.

The aim of this study was to determine the effects of breeder age and stocking density on performance, carcass characteristics and some stress parameters (H-L ratio, serum glucose, cholesterol and triglyceride levels, tonic immobility test (TI), antibody production, relative asymmetry (RA) and external appearances). This experiment was carried out with 705 one-day old male broiler chicks (Ross 308) obtained from three different ages of broiler breeder (32, 48 and 61 wks). Each age group was randomly divided into two stocking density groups (11.9 and 17.5 broilers per $m^2$) with 5 replications per group. The experimental period was 6 weeks. Broilers from 32 wk-old breeders had lower initial weight (p<0.001), body weight gain of the first 3 week of rearing (p<0.01), the percentage of abdominal fat (p<0.001) and serum cholesterol level (p<0.01); higher percentage of gizzard (p<0.01) and longer TI duration (p<0.001) than those from 48 and 61 wk-old breeders. Broilers reared at 17.5 b/m2 had lower final BW, body weight gain, feed consumption, feather condition and foot health (p<0.001), higher percentage of heart, H-L ratio, serum glucose and cholesterol levels (p<0.001), and longer TI durations (p<0.001). There were no significant interactions in examined parameters except for feed to gain ratio between breeder age and stocking density.

This experiment was carried out to observe a biological effect of ginseng on the weight gain, physical performance and lactic acid production after exercise in mice. A group of mice weighing about 19 gm was divided into ginseng and cotrol group. on the treadmill (Exp. I & II) and LDH activity of liver and heart homogenates (Exp. II) were determined. Results are summerized as follows; 1. Body weight gain was greater id ginseng group than in control and the difference was statistically significant at 9th and 16th days of experimental period. 2. Maximal running time of ginseng was found to be longer than that of control (p<0.05) in experiment I and the experiment II also revealed the significant increase in maximal running time in ginseng group. 3. Bloo lactate concentration of 48 hour-rest from physical exertion was lower in ginseng group than in control (p<0.05). 4. LDH activity in liver homogenate was lower compared to control group, but in heart homogenate, it was greater in ginseng group. Above findings may be concluded tat the range of biological dose (20 mg/mice/day) of ginseng powder stimulated the body weight gain and increase of physical performance and its mechanism might be attributable to a lower level of blood lactic acid. The adaptive change of LDH activity also contributed to the change in lactate level in blood and tissue.

Thirty five crossbred male lambs of about 8 months age, with an average body weight of 24 kg were divided into 7 groups of 5 lambs each and were fed urea molasses blocks (UMB) for 150 days (groups 1 to 5); having, 4, 6, 8 and 10% urea respectively; while group 6 was fed concentrate @318 g per head daily and 7th group was kept as control i.e. grazing only. Daily consumption of UMB/concentrate was found to be 318, 246, 211, 93 and 318 g/d for groups 1 to 6, respectively. The statistical differences in consumption between group 1 and group 6, and group 2, 3 and 4 were found to be non-significant. Only group 5 differed statistically from all other groups. The average daily gain was 48, 29, 39, 38, 25 and 66 grams for groups 1 to 6 respectively, while group no. 7 lost 11 g/head/day. The differences in weight gain among groups 1, 3, 4 and 6 were non significant. The expenditure per kg body weight gain was found to be ($Rs^C$) 9.53, 12.45, 8.05, 7.99, 3.69 and 10.85 for groups 1 to 6, respectively.

Citrus sunki Hort. ex Tanaka is one of several Jeju-native citrus fruits. A number of biological properties for citrus fruits have been suggested, however little is known about those of C. sunki. The present study tested whether fermented product of C. sunki peel (FSP) might affect the activities of enzymes regulating ethanol metabolism. Effects on body weight gain as well as on fatty liver formation were also investigated. The activities of alcohol dehydrogenase and aldehyde dehydrogenase were stimulated remarkably by FSP. Excessive ethanol-induced cytotoxicity was also prevented by FSP in HepG2 cells. FSP decreased the weight gain and fatty liver formation induced by a high-fat diet in mice. From these results, FSP might be a potent source of neutraceuticals useful for preventing ethanol-induced health problems.

The methanol extract of leaves of Bruguiera gymnorrhiza (L.) Lam. (Rhizophoraceae) was screened for its antinociceptive and antidiarrhoeal activities. The extract produced significant inhibition in acetic acid-induced writhing in mice at dose of 250 and 500 mg/kg body weight (P < 0.001), comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight (P < 0.001). When tested for its antidiarrhoeal effects on castor oil-induced diarrhea in mice, it increased mean latent period (P < 0.02) and decreased the frequency of defecation (P < 0.01) significantly at the dose of 500 mg/kg body weight, comparable to the standard drug loperamide at the dose of 50 mg/kg of body weight. The overall results tend to suggest the antinociceptive and antidiarrhoeal activities of the extract.
