  • Objective: The purpose of this study was to evaluate the influence of body condition score (BCS) at calving on the metabolic status of female Murrah buffaloes in the transition period. Methods: Thirty-seven pregnant buffaloes (multiparous) were selected and monitored during the transition period based on their body condition score and on the estimated calving date. Two groups were formed: i) buffaloes with a BCS>3.5 (n = 17); this group was classified and named 'high BCS at calving' (HBCS); and ii) buffaloes with a $BCS{\leq}3.5$ (n = 20); this group was classified and named 'low BCS at calving' (LBCS). All animals were monitored during the last 30 days of pregnancy and the first 70 days post-calving and kept in the same environment and under the same feeding and management conditions. Mean values for BCS at calving were $2.98{\pm}0.9$ (mean${\pm}$standard error of the mean [SEM]) and $4.21{\pm}0.9$ (mean${\pm}$SEM) for the HBCS and LBCS groups, respectively. Results: The HBCS group showed higher milk fat content (p = 0.007) and milk fat yield (p = 0.027) and a higher concentration of milk urea nitrogen (p = 0.001) than LBCS buffaloes, which in turn had a lower urine pH value (p = 0.033) than HBCS buffaloes in the pre-calving period (7.86 for HBCS vs 7.76 for LBCS). The HBCS animals had a higher concentration of erythrocytes (p = 0.001) and hematocrit (p = 0.012) post-calving and a higher hemoglobin concentration (p = 0.004) pre-calving. Conclusion: Buffaloes during the transition period exhibited some variations in the oxidative stress related to their metabolic status. After calving, buffaloes with a high BCS at calving and greater lipid mobilization have a more marked alteration in oxidative status, but improved production performance.

  • The childbearing process is a sociocultural phenomenon of a woman who gives birth to a child as well as a biological phenomenon. The purpose of this ethnographic research study was to explore the experience of childbearing process of mothers with children from pregnancy to the 3 months postpartum in Korea and to understand deeply the perspectives of childbearing women reflected on Korean sociocultural values. A convenient sample of 10 childbearing women were observed from January to October 2000 through field work in Seoul, Korea. Data analysis was accomplished under ongoing process. The results of this study were as follows : The mothers with children experienced self-reflection, family relation, and physical adaptation during pregnancy. In self-reflection, all mothers experienced universality and diversity in their self-discovering process. The universal experiences were maturation, life with family and priority on maternal value between being a mother and a woman. The diverse experiences were taking a dual role of working mother, emotional drift of a resigned mother, and disheartened life of a mother who has two daughters. In family relation, the foundation of the new marital relationship were attained during childbearing process and sexual life were changed for the benefit of a healthy mother and a healthy baby. All mothers established friendly relations with their mothers, but established friendly or conflicting or constraining relations with their mother-in-laws due to husband based family culture. In physical adaptation, the informants endured well the physical discomfort and recognized general appearance change. Also maternal-fetal interaction occurred and mothers realistically felt motherhood and accepted themselves as mother-to-be. The mothers prepared for the best delivery, look for a safe childbirth center, newborn goods, endorsed family coping during hospitalization and responded labor pain to make it more endurable, less painful, fast passed owing to labor recognition of the natural process to be a mother. After childbirth, they felt emancipation, satisfaction, accomplishment, more easiness, actually feeling as mother-to-be, emptiness, and showed response to the sex of newborn. Their Sanhujori practice was different according to the Sanhujori environment including provider, place, time in postpartum and reflected on Sanhubyung. The mothers felt actually mother-to-be and happiness during lactation regardless of feeding pattern. These mothers had a different maternal image about rearing subjecthood through their child-rearing experience. But all mothers felt need for family support and social support. The universal rearing response were actual feeling of mother-to-be, a strenuous experience, a pride on child-rearing, confusion, reflecting marital relationship, and wondering rivalry among children. In conclusion, mother of all with children went through self-discovery, self-reflection and made connections with the family as a mother and as a woman simultaneously during the childbearing process. Therefore it is suggested when harmony and balance between a mother and a woman is accomplished, the woman will lead a healthy and high quality of life. Also, this study sought to confirm the sociocultural factors affecting the childbearing process from the perspectives of the women with children. Therefore health care providers must understand deeply the childbearing women with children based on this finding of and try a integrative approach with new ideology of maternity with biocultural perspectives in a clinical setting.

  • The present study was undertaken to investigate the effects of nutrient density diets and sex on carcass and pork quality characteristics in finishing pigs. A total of 96 pigs(58.04 $\pm$ 6.85 kg) were divided into 2 groups(gilts and barrows), each sex group was assigned to 3 nutrient density(high : 18.5%, middle : 16.0% and low: 14.0% CP, respectively) and raised up to 1l0kg live weight. Each treatment had four replicates with three or five pigs per replicate. The treatments comprised the feeding regimes of 1) the low density diet for 60 days, 2) the middle nutrient density diet for the 30 days followed by a low nutrient density diet for the remaining 30 days and 3) the high nutrient density diet for the 30 days followed by a middle nutrient density diet for the remaining 30 days. Pigs were conventionally slaughtered, and then chilled overnight. Carcass characteristics and grades were determined on those carcasses, and pork loin muscle was removed from each left side at 5th to 13th rib for quality evaluation were evaluated. There were no differences in the carcass weight between sex and nutrient density. Dressing percent of L-L(gilts) treatment was significantly higher than that of other treatments(P< 0.05). Barrows showed a thicker back fat thickness than gilts. There were no difference in intramuscular fat, subcutaneous fat and springiness between sex and nutrient density. Intermuscular fat of barrows groups was significantly higher than the gilts groups(P < 0.05). In the meat quality characteristics, there were no difference in general composition, meat and fat color between sex and nutrient density. pH of L-L(gilts) treatment was significantly higher than that of other treatments(P < 0.05). Cooking loss and shear force value of H-M(barrows) treatment were significantly higher than those of other treatments(P< 0.05). Purge loss of barrows groups was significantly higher than the gilts groups(P < 0.05). Myoglobin content of H-M treatment was significantly lower than L-L and M-L treatments(P< 0.05). Texture of H-M treatment was higher than L-L and M-L treatments. The content of myristic, palmitic, palmitoleic and oleic acid were significantly higher in the barrows groups(P< 0.05). However, stearic, linoleic and arachidonic acid were significantly higher in the gilts(P < 0.05). Amino acid content of L-L treatment was significantly higher than M-L and H-M treatments(P < 0.05). In conclusion, carcass and pork quality characteristics were affected by sex and nutrient density.

  • Alcaligenes sp. SH-69에서 탄소원의 고갈 또는 새로운 탄소원의 첨가시 포도당을 단일탄소원으로 하여 생합성된 poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [poly(3HB-co-3HV)] 공중합체의 물질대사 변화 양상을 조사하였다. 회분배양 과정 중 탄소원이 고갈된 후에는 세포 내에 축척되었던 poly(3HB-co-3HV) 공중합체의 분해가 일어나 고분자 함량의 감소와 함께 무게평균 분자량도 감소하였다. 분해 과정 중에는 저분자량의 PHA에 비하여 상대적으로 고분자량의 PHA양이 크게 감소하여 평균 분자량 분포가 보다 낮은 방향으로 이동되는 양상을 보였다. 이에 반하여 1차 탄소원(기질)으로 사용된 포도당의 고갈 직후 2차 기질로서 포도당과 함께 3HV의 전구물질인 levulinic acid를 혼합기질로 첨가해 주었을 경우, 세포 건체량의 지속적인 증가와 아울러 3HV 함량이 높은 poly(3HB-co-3HV) 공중합체의 합성이 이루어졌다. 그러나 아세톤을 이용한 고분자의 분획 실험 결과, 2차 기질로부터의 poly(3HB-co-3HV) 공중합체의 생합성과 1차 기질로부터 생합성된 공중합체의 분해가 동시에 일어나며, 또한 각 기질로부터 생합성된 고분자가 단지 3HV의 함량이 다른 poly(3HB-co-3HV) 공중합체임에도 불구하고 혼합물 형태로 존재하고 있음을 확인하였다.

  • We examined the forage quality to provide the basic information for the utilization of blackberry by-products (leaf and stem) among thirty-five mutant lines derived from gamma-ray. The leaves had higher crude protein (CP) contents than stems. In addition, the leaves showed broad ranges of variation in crude fat, crude fiber and crude ash. The overall forage quality of the stems were similar to those of the original variety. The mean of neutral detergent fiber (NDF) content of leaves and stems in mutant lines were 25.88% and 58.98%, respectively. Also, the mean of acid detergent fiber (ADF) content of leaves and stems in mutant lines were 15.43% and 49.27%, respectively. Forage quality grades of all blackberry leaf were special quality class. However, the blackberry stem ranked $1^{st}$ to $5^{th}$ in quality class. The stem diameter was negatively ($P{\leq}0.05$) correlated with the moisture and crude protein. Also, the fruit length was highly negatively ($P{\leq}0.01$) correlated with the RFV (relative feed value) in blackberry leaf. The one hundred fruit weight was highly negatively ($P{\leq}0.01$) correlated with the crude ash. Based on these results, the by-products of blackberry could provide high quality forage for feeding of live stock.

  • Life table experiments were performed in order to examine the effects of food quality on Moina macrocopa fed with four kinds of algal foods, Botryococcus sp., Scenedesmus subspicatus, Selenastrum capricornutum, and Chlorella sp., at $20^{\circ}C$ . The temperature effects on M. macrocopa were also assessed, feeding Chlorella at $17^{\circ}C$,$20^{\circ}C$,$25^{\circ}C$, and a combination of $28^{\circ}C$ (light) and $25^{\circ}C$ (dark). The cartilaginous Botryococcs cells were Inappropriate food for Moina. Among the foods tested, Chlorella was the food of the best quality in all accounts of life history traits. Moina grown on Chlorella showed higher net reproductive rate ($R_0$), longer mean and maximum longevities, earlier mean age at maturity, longer mean carapace length at maturity, larger mean clutch size, and shorter mean time interval between clutch productions than those grown on Selenastrum and Scenedesmus. An optimal temperature for Moina was $20^{\circ}C$ . When Moina were grown on Chlorella at $20^{\circ}C$, they showed the highest r, the highest $R_0$, the shortest T, the longest mean longevity, the earliest mean age at maturity, the longest mean carapace length at maturity, and the largest mean clutch size. The results of life table experiments showed that the individual and population growth patterns were much more affected by low temperature $17^{\circ}C$, than by high temperature ($\geq 20^{\circ}C$). In the optimal condition, the r value was very high, 5.1 in $d^{-1}$. In conclusion, the food quality and the temperature are the most important factors to govern the size and continuity of Moina population, by which the individual growth rates and reproductivity of members in the population can be controlled to survive in their environment such as small and temporary water bodies in nature.

  • 사료 에너지 수준(고, 저), 깔짚 종류(왕겨, 톱밥), 성별(암 수) 등 세 요인을 각각 달리하여 한협 3호 육계(토종닭)를 대상으로 연구한 결과는 다음과 같다. 깔짚, 사료에너지 수준, 성별 모두 증체량에 영향을 미쳤고, 이들 요인 간 상호효과도 나타났다. 성별에 따라 사료섭취량에 차이가 나타났으나 깔짚이나 사료에너지 수준은 특정 일령의 사료섭취량에만 영향을 미쳤다. 사료요구율은 고 에너지 사료에서 낮았으나, 41~75일령 사료요구율은 차이가 없었다. 지방 이외의 영양소 이용률은 모두 암컷에 비하여 수컷이 높았으며, 지방의 이용률은 성별에 상관없이 저에너지 사료에서 높았다. 가슴육의 색은 사료 에너지 수준과 성별에 따라 달랐고, 다리육의 TBARS가는 암컷에서 높았다. 가슴육의 지방함량은 암컷에서, 다리육의 인과 수분 함량은 수컷에서 높았다. 본 연구로 한협 3호에 대한 사료 에너지 수준, 특히 대부분의 증체가 이루어지는 41~75일령 기간의 사료 에너지 수준을 설정할 때 암 수 간 차이를 두는 것이 바람직하며, 56일령 이후 암컷에는 고 에너지 사료가 오히려 증체량이나 사료요구율에서 불리하다는 점을 알게 되었다.

  • The experiment was designed as a 3 × 3 × 2 factorial arrangement of treatments, including (i) pomegranate peel (zero, 4%, and 8 percent), (ii) oxidized soybean oil (zero, 2%, and 4 percent), and (iii) alpha-tocopherol (zero and 200 mg/kg). Supplementation of 8% pomegranate peel in diets significantly decreased the growth performance of broiler chickens. The supplementation of 4% oxidized oil in diets significantly reduced body weight gain and Feed intake whole experimental period (p < 0.05). The results showed that supplementation of 4% pomegranate peel in the diet was associated with low aspartate transaminase (AST), alanine transaminase, and malondialdehyde (MDA). However, 4% pomegranate peel increased the total antioxidant capacity (TAC) and superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. The supplemental 4% oxidized oil increased the serum AST, alanine aminotransferase (ALT), and MDA concentrations. TAC, SOD, and Catalase (CAT) activities were affected by 4% oxidized oil and alpha-tocopherol. The use of oxidized oil and vitamin E decreased MDA concentration. The serum glucose and globulin concentrations were significantly lower in the 8% pomegranate peel. The results showed that supplementation with 4% pomegranate peel in diets reduced serum low-density lipoprotein (LDL). The inclusion of 4% oxidized oil in diets reduced serum glucose and increased the blood lipid concentration such as triglyceride, cholesterol and LDL. Vitamin E supplementation reduced the serum cholesterol and LDL concentrations. The use of 8% pomegranate peel reduced red blood cell (RBC), hemoglobin, and packed cell value (PCV). The results indicated that supplementation with 8% pomegranate peel and 4% oxidized oil in diets decreased the immunoglobulin concentration in broilers. In addition, it was found that the inclusion of 4% pomegranate peel in diets resulted in higher IgG, IgM and total immunoglobulin. Pomegranate peel supplementation significantly decreased meat MDA concentration. Supplementation of 4% oxidized oil increased MDA of meat (p < 0.05). Vitamin E supplementation (200 mg/kg) significantly decreased MDA of meat (p < 0.05). Consequently, the results of this experiment showed that supplementation with 4% pomegranate peel had beneficial effects on broiler chickens. It was also found that feeding 2% oxidized oil in diets had no adverse effect on broilers.

  • 본 연구는 흑염소를 통해 조릿대를 사료자원으로 이용하고 그 이용성 및 사료가치를 규명하기 위해 실행되었으며, 나아가 조릿대로 인한 한라산 종 다양성 저해문제를 완화하는데 도움을 주기 위하여 실시되었다. 공시가축은 4개월령 비거세 흑염소 12두를 공시하였다. TMR 사료에 조릿대 사일리지의 첨가수준을 다르게 하여 Control(TMR100%), T1(TMR 90% + 조릿대10%), T2(TMR80% + 조릿대20%), T3(TMR70% + 조릿대30%)로 처리하여 총 4가지의 처리구 사료를 각각 제작하였다. 4×4 Latin Square 설계로 실험을 진행하였으며, 총 4개의 스테이지를 구성하여 모든 개체가 모든 처리구를 거치도록 하였다. 일당증체량은 T2에서 142.38g/d로 다른 처리구에 비해 유의성이 인정되었다(P<0.05). 전체적으로 편차가 크게 나타나긴 하였으나, TMR만 급여했을 때 보다 조릿대 사일리지를 첨가하여 급여 한 T1, T2, T3 처리구에서 전반적으로 일당증체량이 높게 나타나는 경향을 보여 조릿대 사일리지의 급여는 육성기 흑염소에 있어서 증체량 향상에 도움이 되는 것으로 판단되었다. 사료요구율의 경우 T2에서 4.4g으로 대조구보다 유의적으로 낮은 수치를 나타내(P<0.05) 다른 처리구에 비해 효율적인 사료급여방식으로 판단되었다. 조릿대 첨가수준에 따른 처리구별 소화율의 유의성은 인정되지 않았으나 T2에서 조지방 및 조단백질, 건물소화율에 있어서 다른 처리구에 비해 비교적 높은 소화율을 보였다. 질소섭취량은 건물섭취량이 많았던 대조구에서 12.5g으로, T3의 11.0g에 비해 유의적으로 높은 섭취량을 나타냈다. 질소축적량은 처리구간 유의성은 인정되지 않았으나 T2구에서 높게 나타났다. 본 연구의 결과를 종합해볼 때, 조릿대 사일리지는 흑염소의 조사료원으로 이용하는데 무리가 없을 것으로 사료되며, 적정량 급여한다면 증체량 및 사료요구율 개선 등 가축생산성 향상에 도움이 될 것으로 판단된다.
