The objective of this study was to determine the effect of replacing corn with soy hulls on nutrient digestibility of growing pigs. Three experimental diets were tested using a 3 × 3 Latin square design using three barrows per group (Landrace × Yorkshire × Duroc, average initial body weight of 36.9 ± 4.0 kg) in individual metabolic cages. The dietary treatments were the control (CON) basal diet (corn-soybean meal based diet), whereas in the test diets, soy hulls were included at 5% (H1), 10% (H2), gradually replacing corn. The daily feed allowance was adjusted to 2.7 times the maintenance requirement for digestible energy (DE) (2.7 × 110 kcal of DE/kg BW^0.75). Intake of crude fiber (CF) was different among treatments (p < 0.05). Pigs fed with H2 diet excreted higher concentrations of dry matter (DM), and CF than pigs fed with H1 diet and basal diet (p < 0.05). Pigs fed with H1 and H2 diets excreted higher concentrations of crude protein (CP) than pigs fed with CON diet (p < 0.05). The apparent total tract digestibility (ATTD) of CF from H1 and H2 diets were higher than CON diet (p < 0.05). Pigs fed with H2 diets were significantly lower (p < 0.05) the ATTD of CP than the pigs fed with CON and H1 diets. The current data suggest that 10% inclusion soy hulls can slightly decrease CP digestibility. However, soy hulls considerably increased CF digestibility.It is concluded that 5% soy hulls may be a usable alternative to corn in growing pig diets.

In mammals, puberty is a dynamic transition process from infertile immature state to fertile adult state. The neuroendocrine aspect of puberty is started with functional activation of hypothalamus-pituitary-gonadal hormone axis. The timing of puberty can be altered by many factors including hormones and/or hormone-like materials, social cues and metabolic signals. For a long time, attainment of a particular body weight or percentage of body fat has been thought as crucial determinant of puberty onset. However, the precise effect of high-fat (HF) diet on the regulation of hypothalamic GnRH neuron during prepubertal period has not been fully elucidated yet. The present study was undertaken to test the effect of a HF diet on the puberty onset and hypothalamic gene expressions in immature female rats. The HF diet (45% energy from fat, HF group) was applied to female rats from weaning to around puberty onset (postnatal days, PND 22-40). Body weight and vaginal opening (VO) were checked daily during the entire feeding period. In the second experiment, all animals were sacrificed on PND 36 to measure the weights of reproductive tissues. Histological studies were performed to assess the effect of HF diet feeding on the structural alterations in the reproductive tissues. To determine the transcriptional changes of reproductive hormone-related genes in hypothalamus, total RNAs were extracted and applied to the semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). Body weights of HF group animals tend to be higher than those of control animals between PND 22 and PND 31, and significant differences were observed PND 32, PND 34, PND 35 and PND 36 (p<0.05). Advanced VO was shown in the HF group (PND $32.8{\pm}0.37$ p<0.001) compared to the control (PND $38.25{\pm}0.25$). The weight of ovaries (p<0.01) and uteri (p<0.05) from HF group animals significantly increased when compared to those from control animals. Corpora lutea were observed in the ovaries from the HF group animals but not in control ovaries. Similarly, hypertrophy of luminal and glandular uterine epithelia was found only in the HF group animals. In the semi-quantitative RT-PCR studies, the transcriptional activities of KiSS-1 in HF group animals were significantly higher than those from the control animals (p<0.001). Likewise, the mRNA levels of GnRH (p<0.05) were significantly elevated in HF group animals. The present study indicated that the feeding HF diet during the post-weaning period activates the upstream modulators of gonadotropin such as GnRH and KiSS-1 in hypothalamus, resulting early onset of puberty in immature female rats.

This study investigated the seasonal and inter-annual changes in vertical distribution and size spectrum of walleye pollock, Gadus chalcogrammus inhabiting middle eastern coast of Korea (hear after pollock). Pollock was distributed between 50 m and 600 m depth range, and body size (total length) ranged from 16.6 cm to 81.5 cm. The trends of population body size were increased in autumn and winter and decreased in spring and summer. Vertical distribution of pollock showned depth-dependent patterns with distributing smaller individuals mainly in the upper layer (shallower depth), while larger fish in deeper habitats. Those patterns in vertical distribution of pollock population is probably due to be the results of energy-saving strategy, metabolic effects, and changes in prey selections according to pollock growth, derived from spatial and temporal changes in oceanic condition in habitat grounds. When water temperature in upper layer were increased and that of below thermocline depth became decreased in 2017, the ratio of smaller (<35 cm) and larger (≥35 cm) individuals was biased toward larger fishes, extending their distribution into shallow depth, and consequently main fishing ground was formed in far from coastal area. In addition, the ratio of smaller individual distributing between 100~300 m was increased with decreasing temperature gradient between below thermocline and bottom layer. Changes in spatial and temporal distributions of pollock population likely be related with vertical and horizontal changes in oceanic conditions and, consequently food supplies.

In order to investigate experimentally the effects of Sung-yangikgibujat'ang (SIT) and Kwangyebujalijungt'ang (KBT) on Yang-insufficient syndrome (陽虛證) induced by Hydrocortisone acetate (H.A.) in experimental animals (Mice and Rat), the author experimented various activities. Delayed type hypersensitivity (DTH), Rosette forming cells (RFC), hemagglutinin (HA) titers, Hemolysin (HL) titers, Body weight, Whole blood viscosity, Plasma Viscosity, Hematocrit, RBC, Albumin, Total protein, Triglyceride, cholesterol and Glucose were measured. The results summerized as follows; 1. In DTH and RFC all the experimental groups were increased significantly in comparison to the H.A.-treated group. 2. In HA titers SIT_treated group were increased significantly and KBT-treated group showed increasing tendancy, but showed no significance. 3. In HL titers all the experimental groups showed increasing tendancy, but showed no significance. 4. In body weight all the experimental groups showed increasing tendancy, but showed no significance. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 6. In plasma viscosity KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 7. In Hematocrit SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. 8. In RBC, albumin and cholesterol all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 9. In total protein and triglyceride KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 10. In Glucose SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. From above findings, it has been demonstrated that Sungyangikgibujat'ang and Kwangyebujalijungt'ang seem to produce the effectiveness on the recovery from depression of the cell-mediated immune response, blood circulation and energy metabolic rate, induced by Hydrocortisone acetate, and in the humoral immune response Sungyangikgibujat'ang have the effectiveness on the recovery, and in cellular component of blood Sungyangikgibujat'ang was more effective than Kwangyebujalijungt' ang, and in plasma of blood Kwangyebujalijungt'ang was more effective than Sungyangikgibujat'ang. Therefore it is suggested that Sungyangikgibujat'ang and Kwangyebujalijungt'ang have the effectiveness on the recovery from Yang-insufficient syndrome more or less.

According to facts revealed up until the present, there are a total of 68 known phyla on earth, including 55 phyla of bacteria and 13 phyla of archaea. The human large intestine has 9 phyla of microorganisms, which is a relatively lower diversity compared to the general environments of soil or sea. The diversity of intestinal microorganisms is affected by the characteristics of the host (genetic background, sex, age, immune system, and gut motility), the diet (non-digestible carbohydrates, fat, prebiotics, probiotics), and the intake of antibiotics, which in turn have an effect on energy storage processes, gene expressions, and even metabolic diseases like obesity. Probiotics are referred to as living microorganisms that improve the intestinal microbiota and contribute to the health of the host; in addition, probiotics usually comprise lactic acid bacteria. Recently, bacteriotherapy using probiotics has been utilized to treat sicknesses like diarrhea and irritable bowel syndrome. Prebiotics are a food ingredient which can selectively adjust intestinal microorganisms and which comprise inulin, fructooligosaccharides, galactooligosaccharides, and lactulose. In recent days, attention has been paid to the use of dietary cellulose in the large intestine and the production of short chain fatty acids (short-chain fatty acids) in relation to obesity and anticancer. More research into microorganisms in the large intestine is necessary to identify specific microorganism species, which are adjusted by diverse non-digestible carbohydrates, prebiotics, and probiotics in the large intestine and to understand the connection between sicknesses and metabolites like short chain fatty acids produced by these microorganism species.

The aim of the present investigation was to investigate the relationship of repeated racehorse simulator exercise on plasma ghrelin and hormons in fasted jockeys. The fasted jockeys and apprentice jockeys performed $1^{st}$ short distance 1000m, $2^{nd}$ middle distance 1700m and $3^{rd}$ long distance 2300m racehorse simulator exercises, and venous blood samples were obtained before, immediately after. In addition to ghrelin concentration, leptin, insulin, insulin-like growth factor-1 (IGF-1), and cortisol values were measured. Pearson correlation coefficients revealed plasma ghrelin and insulin concentration in apprentice jockeys r=.55 after the $3^{rd}$ exercise. There were relationships between significant relationships (p<.05) between plasma ghrelin and leption concentration in jockeys r=.73, and between plasma ghrelin and cortisol concentration in apprentice jockeys r=.64 before exercise. There was no difference in the ghrelin, leptin, insulin and IGF-1 concentration responses to the consecutive exercise. The IGF-1 and cortisol level showed significant (p<.05)difference between groups. In conclusion, these results suggest that negative energy balance induced by of repeated racehorse simulator exercise elicits a metabolic response with positive relationship in plasma ghrelin and insulin in apprentice jockeys after the $3^{rd}$ exercise.

The well preserved ostracodes of the Chunbuk Formation in Pohang Basin were analyzed isotopically to understand paleoceanographic conditions of the southeastern park of Korean peninsula which Songhacdong, and Mulcheonri areas range from - 2.2 to - 0.7% (PDB), - 0.7 to 0.0% , and -20.0 to - 0.8%, and their corresponding paleotemperatures range from ca 20 to 27$^{\circ}C$ (average = 24$^{\circ}C$), 17 to 20$^{\circ}C$ (average = 18$^{\circ}C$), and 20 to 26$^{\circ}C$ (average=23$^{\circ}C$),respectively. Assuming the $\delta$/SUP 18/O composition of the Middle Miocene seawater was about - 0.34% (SMOW), the paleotemperatures of the Middle Miocene shallow seawater in the Pohang Basin was almost equal to or slightly higher than the present summer temperature (ca 16 to 20$^{\circ}C$) near Pohang area. Carbon isotopic value of Cyhere omotenipponica is - 0.8% (PDB), reflecting marine carbonate carbon composition. Carbon isotopic compositions of other ostracodes such as Aurial okumurai, Trachyleberis niitsmai, Urocythereis sp., Urocythereis cf. gorokuensis, and Acanthocythereis mutsuensis range from - 5.2 to - 3.4% (PDB), which might have secreted their shells out of equilibrium with ambient seawater. This disequilibrium was most likely to have resulted from metabolic (=vital) effect, rather than temperature of productivity.

Objective: This study was to investigate the nutrient ileal digestibility of dried mealworm (Tenebrio molitor) larvae and compare with those of three animal protein by-products in growing pigs. Methods: A total of 12 crossbred ($[Landrace{\times}Yorkshire]{\times}Duroc$) growing pigs with average body weights of $24.12{\pm}0.68kg$ were surgically equipped with simple T-cannulas after being deprived of feed for 24 h according to published surgical procedures. These pigs had a recovery period of two weeks. A total of 12 pigs were assigned to individual metabolic crates and allotted to one of four treatments with 3 replicates in a fully randomized design. Dietary treatments included the following: i) Fish meal, corn-vegetable by-product basal diet+9.95% fish meal; ii) Meat meal, corn-vegetable by-product basal diet+9.95% meat meal; iii) Poultry meal, cornvegetable by-product basal diet+9.95% poultry meal; iv) Tenebrio molitor, corn-vegetable by-product basal diet+9.95% dried Tenebrio molitor larvae. Results: Results showed that the apparent ileal digestibility (AID) of Lys was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal diet. Pigs fed Tenebrio molitor diet showed increased (p<0.05) AID of His and Arg compared to pigs fed Fish meal or Meat meal diet. The AID of Cys was increased (p<0.05) in pigs fed poultry meal and Tenebrio molitor diets compared to that in pigs fish meal diet. Pigs fed meat meal, poultry meal, and Tenebrio molitor diets showed higher (p<0.05) standardized ileal digestibility (SID) of total energy compared to pigs fed fish meal diet. The SID of Arg was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal or meat meal diet. Furthermore, pigs fed poultry meal or Tenebrio molitor diets showed increased (p<0.05) SID of Cys compared to pigs fed fish meal diet. Conclusion: In conclusion, providing pigs with diets that contained Tenebrio molitor larvae meal improved AID and SID of nutrients as well as essential and non-essential amino acids. The digestibility of dried mealworm larvae protein and its utilization in vivo are also good. Therefore, dried mealworm larvae protein can be used as protein source at 10% level in growing pigs.
