This experiment was conducted on 60 Hanwoo calves comprising five feed additive groups, with 12 calves in each group, to determine the effects of additives at pre- and post-weaning on growth performance and blood profile. The groups were control, antibiotic (Neomycin 110 ppm), illite (2%), fermented green tea probiotics (FGTP, 0.5%), and mixed additives (FGTP 0.25%, illite 1% and licorice 0.1%). The calves were offered experimental pellet feeds ad libitum and after one month were supplied with imported timothy hay. They moved freely within the group and suckled their mother' milk during the pre-weaning stage (birth to 3 months) and were separated from their dam during the post-weaning stage (4-5 months). During the pre-weaning stage, the highest average daily gain (ADG) was recorded in the antibiotic- and mixed additive-fed groups followed by FGTP, control and illite groups. In the post-weaning stage, significantly higher total weight gain and ADG were recorded in both the FGTP and mixed additive groups compared to the other groups (p<0.05). Feed efficiency of mixed additive- and illite-fed calves were almost similar with antibiotic-fed calves compared to the other two groups, but the ADG was lowest in illite-fed calves during the pre-weaning stage. In contrast, post-weaning calves fed FGTP and mixed additives showed better feed efficiency. The values of hematological indices, differential leukocyte count, blood proteins and immunoglobulin among the additive-fed calves were not significantly different (p>0.05), although hemoglobin and hematocrit values were lower in FGTP compared to control, but similar in mixed additive and antibiotic groups. These results indicate no detrimental effects of feed additives on the blood profile of calves at both pre- and post-weaning age. Serum albumin in post-weaning calves of all feed additive groups were similar but significantly lower (p<0.05) than in the control group. Post-weaning, IgM was significantly lower (p<0.05) in illite-fed calves compared to other treatment groups, but there was no difference at pre-weaning. Considering all factors, the mixed feed additives and FGTP can be the replacement feed formula for antibiotic for Hanwoo beef calf production, especially when used post- weaning.

Objective : This study was conducted to investigate anti-obesity effects of mixed-Powder(Raphani Semen, Coicis Semen, Poria, Plantaginis Testa & Theae folium)(HP) & mixed water extract(Citri Pericarpium, Crataegi Fructus, Maydis Stigma, Allium Skin) (HE) in mice fed a high-fat diet. Method : 50 Female ICR mice were divided into six groups; Normal group (Ve), high-fat diet group (Po), Po+HP(0.6g/kg) group(HP), Po+HE(1g/kg) group(HE), Po+(HP+HE) group(HPE), Po+(HP+HE)*2 group(DHPE). For 8 weeks, these groups were fed their respective diets. Body weight, liver weight and weights of adipose tissues, GOT/GPT index changes & Blood Glucose index changes were measured respectively. Lipid profiles in serum were analyzed by kit of blood. Results : Groups HP, HE, HPE, DHPE had significantly reduced body weight, liver weight, adipose tissue weights and GOT/GPT index, blood glucose index compared to the Po group. Also, serum triglyceride and total cholesterol, low density lipoprotein, were significantly reduced when compared to the Po group. Group G1 had significantly increased high density lipoprotein levels. Conclusion : Mixed powder (HP) & mixed water extract (HE) show anti-obesity effects in mice fed a high-fat diet.

The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.

This study investigated the nutritive quality of olive flounder Paralichthys olivaceus fed either moist pellet (MP) or moist pellet mixed with mushroom extract (MPME) for 6 months. There was no significant difference in crude protein or extractive nitrogen in the muscle of flounder fed MP versus MPME (P > 0.05). The total amino acid content in the muscle of flounder fed MP was $15.22{\pm}5.24$ g/100 g, compared to $19.90{\pm}2.90$ g/100 g for flounder fed MPME. Essential amino acid content was $7.04{\pm}2.21$ g/100 g in the muscle of flounder fed MP versus $8.94{\pm}2.50$ g/100 g for MPME. Total amino acid content was higher in the muscle of olive flounder fed MPME, while essential amino acid content was higher in flounder fed MP. The ratio of non-essential amino acids to essential amino acids was $0.86{\pm}0.07$ for flounder fed MP and $0.81{\pm}0.08$ for flounder fed MPME. There was no significant difference in free amino acid content and fatty acid composition. The breaking strength of muscle of olive flounder fed MP was higher ($1.44{\pm}0.51\;kg/cm^2$) than in flounder fed MPME ($1.29{\pm}0.30\;kg/cm^2$). There was no evidence that dietary additives, such as mushroom extract, increase growth rate or nutritive quality of olive flounder.

This study selected the optimal microalgal species for mass culture of a brackish water copepod Paracyclopina nana. Fifteen microalgal species were tested to examine nauplius production and the survival and maturation of brood females. Total and daily nauplius production were highest in P. nana fed Tetraselmis suecica followed Isochrysis galbana, Dunaliella tertiolecta, and Phaeodactylum tricornutum. With a monospecific microalgal diet, the total density was highest with P. nana fed I. galbana, at 63.3 inds./mL. With a mixed microalgal diet, the total density of P. nana fed T. suecica+I. galbana was higher than that fed other mixed diets, although there was no difference between a monospecific diet of I. galbana and a mixed diet of T. suecica+I. galbana. Examining the fatty acid composition of P. nana, the eicosapentaenoic acid (EPA) was highest in P. nana fed T. suecica at 5.4% while the docosahexaenoic acid (DHA) content was highest I. galbana diet at 31.9%. Although no DHA was detected in T. suecica, P. nana fed this microalgal species had a high DHA composition of 24.3%. We suggest that the optimal microalgal species for the mass culture of P. nana is T. suecica which is easy to culture on masse and has a high linolenic acid content.

Objective: The objective of this study was to investigate effects of mixed organic acids (MOA) on nutrient digestibility, volatile fatty acids composition and intestinal microbiota in growing-finishing pigs fed high wheat bran diet. Methods: Six crossbred barrows ($Duroc{\times}Landrace{\times}Yorkshire$), with an average body weight $78.8{\pm}4.21kg$, fitted with T-cannulas at the distal ileum, were allotted to a double $3{\times}3$ Latin square design with 3 periods and 3 diets. Each period consisted of a 5-d adjustment period followed by a 2-d total collection of feces and then a 2-d collection of ileal digesta. The dietary treatments included a corn-soybean-wheat bran basal diet (CTR), mixed organic acid 1 diet (MOA1; CTR+3,000 mg/kg OA1), mixed organic acid 2 diet (MOA2; CTR+2,000 mg/kg OA2). Results: Pigs fed MOA (MOA1 or MOA2) showed improved (p<0.05) apparent total tract digestibility (ATTD) of gross energy, dry matter and organic matter, and pigs fed MOA2 had increased (p<0.05) ATTD of neutral detergent fiber compared to CTR. Dietary MOA supplementation decreased (p<0.05) pH value, and improved (p<0.01) concentrations of lactic acid and total volatile fatty acids (TVFA) in ileum compared to CTR. Pigs fed MOA showed higher (p<0.05) concentration of acetic acid, and lower (p<0.05) content of formic acid in feces compared to CTR. Pigs fed MOA1 had increased (p<0.05) concentration of TVFA and butyric acid in feces. Pigs fed MOA1 showed higher concentration of Lactobacillus and lower concentration of Escherichia in feces compared to CTR. Conclusion: Dietary supplementation of MOA 1 or 2 could improve nutrients digestibility, TVFA concentration and intestinal flora in growing-finishing pigs fed high fiber diet.

The purpose of this research is to evaluate the effects of a commercial mixed extruded pellet(EP) and raw fish moist pellet(MP) diet on diseases prevalence and serological constituents and HSI of korean rockfish, Sebastes schlegeli grown in two commercial-scale aquaculture farms from June to December in 2009. The growth of MP-fed rockfish was slightly faster than EP-fed rockfish during experimental period, but did not show significant differences. The levels of TCHO, TG, Glucose and TP in the MP-fed rockfish group were higher than those of EP-fed group, whereas there was no significant difference in other biochemical factors of blood between two groups. In addition, bacteria and virus were not detected in both MP- and EP-fed rockfish groups, and the infection rates of gill fluke between two groups did not show clear difference. In conclusion, there was no comparable difference in growth and the health extents of one year rockfish by administration of the commercial mixed extruded pellet(EP) and raw fish moist pellet(MP) diets.

A feeding trial was conducted to study the replacement value of concentrates with Barhar (Artocarpus lakocha) leaves on growth performance of kids fed a mixed jungle grass-based diet. Fifteen Sikkim local kids, about 4 months of age and body weight ranging from 5.8 to 9.2 kg, were randomly distributed into three groups of five. Kids were stall fed ad lib with mixed jungle grass collected from the nearby forest and native scrubland. The kids in group I received supplementary concentrate (Maize 35%, mustard cake 32%, rice bran 30%, mineral mixture 2% and common salt 1%) at approximately 2% of BW. For groups II and III, 25 and 50% of the concentrate was replaced with Barhar (Artocarpus lakocha) leaves, respectively. Total dry matter intake (DMI) was not significantly different among groups. Digestibility of CP decreased (p<0.05) and that of NDF increased (p<0.01) with increasing level of Barhar leaves in the diet. Digestibility of ADF (p<0.01), hemi cellulose (p<0.05) and cellulose (p<0.01) was higher in groups II and III than in group I. Ruminal pH and TVFA concentration were not significantly different among groups. Rumen ammonia-N concentration decreased (p<0.01) with increased level of Barhar leaves in the diet. Similarly, plasma urea nitrogen and blood glucose levels were reduced (p<0.05) with increasing level of Barhar leaves in the diet. Replacement of concentrate with Barhar resulted in reduced Hb and lower serum iron concentration. Levels of other serum metabolites including minerals were not altered by the replacement. Average daily gain (ADG) was 53.3, 54.4 and 41.8 g/d in groups I, II and III, respectively. ADG was not adversely affected when the level of replacement was restricted to 25%. However, at 50% of replacement ADG was significantly lower than the control (p<0.05). Thus, it was concluded that Barhar leaves might replace 25% of the supplemental concentrate for growing Sikkim local kids fed on a mixed jungle grass-based diet.

The objective of this study was to determine the effect of dietary oils on the levels of the ${\gamma}-linolenic$ acid in chicken meat lipids. Three hundred ten five, 1-d old, male, Ross strain, broiler chicks were fed for 35 d to compare diets containing evening primrose oil(EPO) and hemp seed oil(HO) to a control diet. Fatty acid composition of lipid from chicken skin, thigh and breast muscle were determined at the end of the trial. The level of ${\gamma}-linolenic$ acid of lipids from chicken meat fed diets containing EPO or HO was significantly higher than that of the control group(p<0.05). The level of ${\gamma}-linolenic$ acid of lipids from chicken skin was highest in the group, which had been fed the EPO 0.85%, followed in order by EPO 0.7%, 0.5%, EPO mixed oil, HO and HO mixed oil. There was a significant difference in the level of ${\gamma}-linolenic$ acid of chicken skin between the control and treatment groups(p<0.05). The level of ${\gamma}-linolenic$ acid of lipids from chicken thigh muscle was also similar to skin, and significantly higher than that of the control group(p<0.05). The level of ${\gamma}-linolenic$ acid of lipids from chicken breast muscle was highest in the group, which had been fed the EPO 0.5%, followed in order by EPO 0.7%, 0.85%, HO 0.5% and HO mixed oil. There was a significant difference in the level of ${\gamma}-linolenic$ acid of chicken breast muscle between the control and treatment groups(p<0.05).

The solids(supplementary food) consumption of 200 healthy infants aged from 4 to 6 months have been measured. Five groups were assigned to different feeding patterns. Breastfed group(BF, n=38), formula-fed group(FF, n=102) and mixed-fed group(MF, n=14) were fed breast milk, formula and mixed(breast mile+formula) from birth until 6 months of age respectively. Convert 1 group(C1F, n=14) and convert 2 group(C2F, n=32) were fed breast milk and mixed milk at 2 months of age respectively and were switched to formula thereafter. All infants received solids form 4 months of age. The energy intake from solids at 4 and 6 months averaged 59.1 and 110.3㎉/d among BF groups vs 151.9 and 239.3㎉/d among FF groups respectively. Intakes of protein, calcium and iron were 38-46$\%$, 34-44% and 25-37$\%$ higher in the FF than in the Bf group during the first 6 months. However, no significant differences were found in the intakes of energy and nutrient intakes from solids in all 4 groups excluding BF group(39$\%$). Although BF infant's nutrient intakes from solids were lower than other group's intakes, they intaked evenly solids from various food groups. As the age of infant had increased, the energy intake ratio from solids was cereals and dairy products was increased whereas energy intake ratio from meats, eggs, fruits and vegetables was decreased. TSC4, TSC6(the frequency score for the kinds of weaning food taken) showed no significant difference among 5 feeding groups but CIF-and C2F group's scores tended to be high. Consequently, these results suggest that BF group's solid intake pattern is more desirable and that Korean lactating Mother's dependence on commercial weaning food is too high.
