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.

현재까지 밝혀진 사실에 의하면 지구상에는 55개 phylum의 bacteria와 13개 phylum의 archaea가 존재하여 총 68개 phylum 있으며, 대장에는 9개 phylum의 미생물이 존재하여 일반 토양환경이나 해양환경에 비하여 상대적으로 낮은 미생물 다양성을 가지고 있다. 장내 미생물의 다양성은 Host의 고유특성(genetic background, sex, age, immune system, gut motility)과 식이(nondigestible carbohydrates fat, prebiotics or probiotics), 항생제 섭취 등으로 인하여 영향 받으며, 이러한 영향이 에너지 저장 과정과 유전자 발현을 영향을 주고 나아가 비만과 같은 대사질환에 영향을 미친다. Probiotics는 숙주의 장내 균총을 개선하여 건강에 유익함을 줄 수 있는 살아있는 미생물을 말하며, 주로 lactic acid bacteria들이 이용되어 왔다. 최근 probiotics를 이용한 설사나 과민성대장증후군 등과 같은 질병 치료를 위하여 bacteriotherapy가 활용되고 있다. Prebiotics는 장내 미생물을 선택적으로 조절할 수 있는 식품 성분으로 inulin, fructo-oligosaccharides, galacto-oligosaccharides, lactulose 등이 이용되고 있으며, 최근에는 비만, 항암과 관련하여 대장 내 식이섬유소의 이용과 단쇄지방산(short-chain fatty acids) 생산에 대한 관심이 집중되고 있다. 다양한 nondigestible carbohydrates와 prebiotics, probiotics에 의해서 조절되는 대장 내 특정 미생물 종을 규명하고, 이들 미생물 종이 생산하는 단쇄지방산과 같은 대사산물들과 질병과의 연관성 규명하는 대장 미생물 연구가 더욱 필요하다.

포항분지 내의 천북층에서 산출되는 변질되지 않은 개형충 화석을 대상으로 중기 마이오세 동안에 한반도 남서부 부근에 영향을 주었던 고해양학적 조건을 이해하기 위 하여 동위원소 분석을 실시하였다. 서정리, 송학동 및 물천리 지역의 변질되지 않은 개형충의 산소동위원소 성분은 각각 -.2.2~ -0.7$\textperthousand$(PDB), -0.7~0.0$\textperthousand$ 과 -2.0~ -0.8$\textperthousand$이며, 이 성분에 의한 고해양해수의 온도는 각각 20~27$^{\circ}C$ (평균=24$^{\circ}C$), 17~2 $0^{\circ}C$ (평균=18$^{\circ}C$)과 20~26$^{\circ}C$ (평균=23$^{\circ}C$) 정도이다. 만일 중기 마이오세 동안에 포항 분지내 천해 해수의 산소동위원소 성분이 약 -0.34$\textperthousand$ (SMOW)이었다고 가정하면, 중기 마이오세 동안에 포항분지내 천해 해수의 고온도(paleotemperature)는 현재 포항부근 천해의 평균여름 온도와 거의 비슷하였거나 약간 높았던 것으로 추정된다. 분석된 개 형충 중 Cythere omotenipponica의 탄소동위원소 성분은 -0.8$\textperthousand$(PDB)로서 해수내의 탄 산염이온의 탄소동위원소 성분을 잘 반영하고 있으나, Aurial okumurai, Trachyleberis niitsmai, Urocythereis sp., Urocythereis cf. gorokuensis, and Acanthocythereis mutsuensis와 같은 나머지 개형충의 탄소동위원소 성분은 -5.2~ -3.4$\textperthousand$(PDB)로서 주위의 해수와 비평형상태를 이루고 있었던 것으로 나타난다. 이러한 결과는 고해양해수의 온도나 생산력의 차이에 의한 영향이라기 보다는 개형충 자체 내 의 생리적 영향에 기인한 것으로 여겨진다.

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.
