For the purpose of ascertaining the status of physical growth and food habit of obese children, a study was made of 1086 primary school children ranging between 2nd and 3ra grades living in Kwang-ju City in Korea. 66 subjects were selected from an anthropometrical point of view and they were classified into two groups, an obese group and a control group, according to their relative body weight. Food habits of each group were observed by means of questionnaires. In the statistical analysis of the data, percentage calculation and T-score test were used. The results of the study can be summarized as follows; 1) Viewed from relative body weight, 3.0% of the 1,086 subjects turned out to be obese, and the measure of skinfold showed 2.4%. 2) Physical growth of the obese growth is superior to that of the control group in all aspects. 3) The average score of food preference by means of Hedonic scaling method by the obese group is 3.90, while that of food preference by the control group is 3.76. The most favored food by the obese group is ice cream (4.91), while that of most favored food by the control group is banana (4.75). The statistically meaningful foods of the two groups are cucumber (0.02>p>0.01), orange (p<0.02), peach(0.05>p>0.02), watermelon (p <0.01) and ice cream (p<0.01). The score of food preference for protein foods by the obese group is 3.78 and that of food preference by the control group is 3.57(0.05>p>0.02). The excessive food intake per meal of the obese group is 45.4%, while that of the control group is 19.7% (0.05>p>0.02). Ratio of taking severely unbalanced food by the obese group is 15.1%, while that of the control group is 50.0% (p<0.01). 4) 30.3% of mothers of the obese group is fat, while 15.1% of mothers of the control group is fat (p<0.01). Concerning body weight at birth, 90.9% of the obese group and 63.6% of the control group are above-average weight. (p <0.01). From the results shown above, the obesity in children is almost due to food. It is hoped, therefore, that overeating be discouraged through the nutrition education.
Ten growing male buffalo calves (aged 6-8 months, average body weight $88.2{\pm}0.57$ kg were divided randomly into two groups. Animals in group I were fed on concentrate mixture A (CP 20.2%, TDN 77.4%) and urea- ammoniated wheat straw (UAWS) while the animals in group II were fed on concentrate mixture B (CP 17.9%, TDN 77.6%) and HCl plus urea treated wheat straw (HCl UAWS) to meet their nutrient requirement for 500 g gain/d as per Kearl (1982). This feeding practice lasted for 120 days, during which fortnightly body weight were recorded to assess their growth rate. A metabolism trial was conducted after 90 days of experimental feeding to compare the digestibility of nutrients, their balance, plane of nutrition and relative cost of feeding in two groups of animals. Results revealed a significant increase in the CP content of ammoniated wheat straw due to addition of HCl viz 12.1% from 7.5%. There was a decrease in the intake of DM (p<0.05), OM (p<0.05), EE (p<0.05), NDF (p<0.01), ADF (p<0.01), cellulose (p<0.01) and hemicellulose (p<0.01) in group II as compared to group I. The digestibility (%) of DM, OM and CP was significantly (p<0.01) more in group II, whereas the digestibility (%) was significantly more for NDF (p<0.05) and hemicellulose (p<0.01) in group I than group II. There was no significant difference in the N, Ca and P balance in two groups. Intake of total DM (g/d) or (g/kg $W^{0.75}$) was significantly (p<0.01) more in group I as compared to group II, whereas the intake of DCP and TDN (g/d or g/kg $W^{0.75}$) was alike in two groups. The total body weight gain (kg), average daily gain (g/d) and feed conversion efficiency were significantly (p<0.01) more in UAWS fed group as compared to HCl UAWS fed group. Feeding cost (Rs./kg. weight gain) was significantly (p<0.05) more in group II as compared to group I. It is concluded that HCl UAWS is not suitable for the feeding of growing buffalo calves as it reduced the growth rate in comparison to UAWS fed buffalo calves.
This study was conducted to investigate the variation of growth characteristics and reproductive physiology in cloned Hanwoo male calves during growing stage. The hematological parameters, body weight, and plasma hormonal levels, birth to 12 months, were analyzed in the cloned calves (n=3). Differences among treatment means were determined by a student t-test. A probability of P<0.05 was considered statistically significant. The hematological parameters, such as white blood cell, red blood cell, and platelet, were not different in both normal and cloned calves. The difference of body weight, however, was significantly higher in the cloned calves, $5{\sim}6$ months (p<0.05) and $7{\sim}12$ months (p<0.01), than that of the comparators, respectively. The plasma IGF-1 level was statistically significant in the cloned calves, $5{\sim}10$ months, compared to that of the normal calves (p<0.05). However, the plasma testosterone level was not different in both normal and clone calves according to growing stage. Taken together, the cloned Hanwoo male calves are growing faster and maintaining a normal reproductive physiology.

This experiment was conducted to investigate the effects of soybean meal (SBM) of different origin (Korea, India or Brazil) on performance, fecal microflora and economics of grower pigs. A total of 144 grower pigs (initial BW, 10.4 kg) were randomly allotted to six treatments on the basis of BW. Pig's diets containing SBM were formulated based on the total amino acid (TAA) or true ileal digestible amino acid (TIDAA) levels. Pigs fed domestic SBM diets had greater (p<0.05) overall ADG, ADFI and final body weight and apparent total tract digestibility (ATTD) of DM, GE and CP (phases I, II and III) than those fed diets containing SBM originated from India or Brazil. Moreover, greater (p<0.05) ADG, ADFI, feed /gain (F/G), and ATTD of DM, GE and CP were observed in response to diets formulated on a TIDDA basis when compared with those formulated on a TAA basis. The fecal microflora was not affected (p>0.05) by dietary treatments. The overall feed cost per kg body weight gain was less (p<0.05) for diets formulated using domestic SBM than for those containing SBM from India, while the feed cost per kg body weight gain was less (p<0.05) for diets formulated prepared on a TIDAA than a TAA basis. These results indicate that domestic SBM has better quality than SBM imported from Brazil or India and better performance was obtained when diets were formulated based on the true ileal digestible amino acid (TIDAA) content.

An experiment was conducted to determine the effects of soybean oil supplementation replacing tallow in pig diets at different stages of growth. One hundred and twenty crossbred (Landrace${\times}$Yorkshire${\times}$Duroc) pigs weighing 18 kg on average were selected. Pigs were randomly allotted to 12 pens of 10 pigs (5 pigs of each sex) each. Three pens were assigned to each of the four treatments: TA; tallow diet, TA-SO-80; switched from tallow to soybean oil diet at 80 kg average body weight, TA-SO-45; switched from tallow to soybean oil diet at 45 kg average body weight, and SO; soybean oil diet. Treatment SO was significantly lower in ADG than tallow diets (TA, TA-SO-80 and TA-SO-45) during the grower period (18 to 45 kg). However, treatment SO showed greatest compensation in ADFI and ADG during the finisher-2 period (after 80 kg body weight). ADFI and ADG and Gain/Feed for the total period were not significantly different among treatments. Loin area, back fat thickness, firmness and melting point of back fat were not significantly different. The levels of total cholesterol and low density lipoprotein+very low density lipoprotein cholesterol in serum were significantly lower in treatment SO than in treatments TA-SO-45, TA-SO-80 and TA. The level of serum triglyceride linearly increased as the length of the tallow feeding period increased. Serum immunoglobulin-G (IgG) level was significantly higher in the soybean oiltreatment than in other treatments. Major fatty acid composition of short rib muscle and back fat were significantly influenced by treatments. Contents of ${\alpha}$-linolenic acid (C18:3) and docosahexaenoic acid (DHA, C22:6) linearly increased as the soybean oil feeding period increased. In conclusion, soybean oil can be supplemented to the diet of pigs without significant effects on growth performance and carcass characteristics. The level of polyunsaturated fatty acids (PUFA), especially $\omega-3$ fatty acids in the carcass was increased by soybean oil supplementation.

Information on nutrient requirements and forage intake of fallow weaner deer is required for the development of feeding strategies during the year. An experiment was conducted in which 60 fallow weaner deer (grazing on medic and ryegrass based pastures) were supplemented with a concentrated diet at three levels. The diet contained 2% minerals, 30% lupin and 68% barley grain. Twelve deer from each treatment were dosed with commercial alkane capsules in May, June, July, September and October to predict nutrient intake. The relationships between body weight gain and intake of metabolisable energy and crude protein were established using a general linear models analysis. Dry matter intake from pastures ranged from 0.137 kg to 0.304 kg in May and June and increased to 1.2 kg in October. Nutrient intake from pastures was strongly influenced by amount of supplementary feed and gender. Digestible energy intake from pastures was 1.3, 3.8 and 6.1 MJ/day higher for males than females in July, August and October, respectively. The protein and energy intake was strongly correlated with body weight gain. The energy requirement for maintenance were 7.3, 8.2, 10.2, 10.2 and 10.7 MJ DE/day and the DE required for each kg body weight gain were 19, 18, 29, 34 and 49 MJ in May, June, August and October, respectively. The protein requirement for maintenance was 12.2, 12.6, 15.0, 11.4 and $8.5g/W^{0.75}$ in May, June, July, August and October, respectively. The nutrient requirement defined from this study can be used to assist farmers to explore the possible pasture and stock management practices under southern Australian conditions. However, further research is required to develop rapid and cheap methods for estimating dry matter intake, nutritive value of pastures and to quantify the potential growth rate of fallow deer in southern Australia.
A factorial experiment was conducted to assess nutrient utilization by growing lambs maintained on three levels each of digestible energy (high: HE, medium: ME, low: LE) and protein (high: HP, medium: MP, low: LP) in nine combinations (HEHP, HEMP, HELP, MEHP, MEMP, MELP, LEHP, LEMP, LELP). The experiment was conducted during the hot season in a semiarid location. Daily dry matter intake (DMI) was similar in all the groups in terms of unit body weight or metabolic body size. Digestibility of DM and nitrogen free extract increased (p<0.01) from low to medium and high energy regimen while the CF digestibility followed a reverse trend. The digestibility of crude protein (CP) decreased from high to medium and low protein regimens while it was similar in terms of energy variation. Nitrogen intake was higher in high followed by medium and low protein regime while fecal and urinary nitrogen loss were similar in all the treatment groups. Lambs in all the three levels of protein were in positive N balance and percent N retention was higher (p<0.01) in high followed by medium and low protein levels whereas it was similar in terms of energy variation. Initial body weight was similar in all the groups while final weight, total gain in the experiment and average daily gain (ADG) were higher in high than medium and low energy regimens. It is concluded that crossbred lambs required 75.1 g DM, 9.6 g CP, 6.3 g DCP and 711 KJ DE/kg W $^{0.75}$or 11.0 g CP/MJ DE or 7.2 g DCP/MJ DE for 93 g average daily gain in a hot semiarid environment.
This experiment was carried out to investigate effects of honeybee venom treatment on the body weight gain, feed conversion and growth rate' in pigs. One hundred twenty nine piglets(LY) from 12 sows were allocated into two groups; honeybee venom-treated group (66 piglets from 6 sows) and non-treated control group (63 piglets from 6 sows). Natural honeybee venom was administrated at 0, 3, 14, 30, and 74 days after birth. The acupoints were Hai-men(ST-25), Du-kou(CV-8) and liao-chao(GV-I) points at 0 day, the regions of castration and tail ampution at 3 days, liao-chao(GV-1) and Bai-hui(GV-20) points at 14(weaning), 30(move into piglet stall) and 74(move into grower stall) days after birth. Control group was injected 1 ml of saline to the same site. Average body weight at 150 days after birth was 98.44 kg in bee venom treated group and 86.24 kg in control group, respectively. Average body weight of treated group was significantly increased by 14.15%(P < 0.0001). Average daily gain of bee venom treated group and control group were 649 g and 569 g, respectively, increased by 14.06%(P< 0.0001). Feed conversion of the treated group was 2.21 and control group was 2.49, increased by 11.25% in control group(P < 0.001). Survival rate at weaning was 95.5 % in treated group and 92.0% in control group, at growing(74 days after birth) was 92.4% in treated group and 85.7% in control group and survival rate at finishing(l50 days after birth) was 89.5 % and 79.4 %, respectively. Collecting together, the results in this study showed that growth performance and feed conversion were increased by treatment of natural honeybee venom to pigs. These results suggested that the treatment of bee venom could be used effectively for the increase productivity of livestock industry.
This study was performed to investigate the growth rate, hematological and serological changes of the rats when they were fed with the high fat diets supplemented with or without the tannic acid for five weeks. Thirty-two Sprague-Dawley male rats(235.7\pm10.7g\;of\;body\;weight)$ were randomly divided into four groups, control group and three treatment groups(T1, T2 and T3). Rats in control group were fed with the high fat diet containing $15\%\;lard,\;1\%$ cholesterol and $0.5\%$ sodium cholate(wt/wt) which was modified from the formula of American Institute of Nutrition (AIN)-76 diet and rats in treatment groups were fed with above diet supplemented with $0.25\%(T1),\;0.5\%(T2)$ or $0.75\%(T3)$ of tannic acid(wt/wt), respectively. The supplementation of tannic acid(TA) did not affect the final body weight, gain of body weight and feed intake of rats in both control and treatment groups. The numbers of red blood cells, hemoglobin concentrations and hematocrit values in blood of rats showed no significant differences between control group and treatment groups. The glucose concentration and albumin/globulin(A/G) ratio of rats in treatment groups were slightly lower than that of control group without significance. The values of total protein, albumin and globulin showed no significant differences between control group and treatment groups. The values of total cholesterol, low density lipoproteincholesterol and atherogenic index in sera of rats in treatment groups were much lower than that of control group without significance. The values of triglycerides in sera of rats in T3 group were significantly lower than that of control group (p<0.05). The values of AST and ALT in sera of rats in T3 group were significantly lower than that of control group (p<0.05). Thus supplementation of tannic acid to high fat diet could be effective to reduce the serum lipid levels such as total cholesterol, high density lipoprotein-cholesterol and triglycerides which were regarded as to cause the cardiovascular diseases.
This study was conducted to investigate the antibiotic effects of bee venom (Apis mellifera) on the growth performance and blood characteristics in broiler chicken. 1-day-old broiler chicks were randomly divided into 3 groups with 3 replicates of 5,000 birds each. The treatments were control without antibiotic and bee venom, 0.5ppm or 1ppm bee venom. The final body weight and body weight gain were significantly higher in bee venom than control (P<0.05). The feed conversion ratio in all treated groups were significantly improved as compared to that of control (P<0.05). No significant differences among the groups were observed in the contents of total cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein, albumin and globulin in blood serum. The white blood cell, red blood cell, heterophil, lymphocyte, and stress indicator (heterophil:lymphocyte rate) were not significantly different among the groups. The superoxide dismutase-like activities in the groups that were water containing bee venom were significantly increased compared to those in the control group (P<0.05). It has been suggested that bee venom promotes the growth of broilers without any negative effect when added in broiler water.
