Because sows are industrially vital for swine production, monitoring for their health or disorder status is important to ensure high reproductive performance. Especially, ambient temperature changes in different season, especially during summer, are directly influenced to the reproductive performance of sows. Although the serum biochemical parameters are widely applied in the veterinary medicine with wide ranges for the physiological process, the values are also influenced by several factors such as age, breed, gender, and stress. In addition, domestic sows in Korea-specific reference interval (RI) for serum biochemistry has not been established yet. Therefore, the present study was aimed to evaluate seasonal variation of RIs in the serum biochemistry in domestic sows in Korea at different seasons and to establish normal RIs using a RI finding program (Reference Value Advisor). Significant difference (p < 0.05) on the different seasons were identified in several serum biochemical parameters including BUN, CRE, GGT, GLU, ALB, TP, LDH and Na in sows. Therefore, we further established RIs, specific in domestic sows in Korea regardless of season. The established RIs based on the serum biochemical values provide a baseline for interpreting biochemical results in the domestic sows in Korea, regardless of seasonal effect. It may contribute to develop a strategy for better reproductive performance by improving breeding management practice and evaluating health of pig herds, which facilitate to avert the economic loss in summer infertility in sows.

In order to provide an effective preparedness for a nuclear or radiological emergency happening in the domestic or neighborhood countries and to solve the vague fear of the people for the ingestion of radioactive livestock products, the establishment of national guideline level for radionuclides in feed is urgently necessary. This is because it is important to secure the safety and to manage the crisis in the agricultural, fishery and food sector by performing the effective safety control during and after nuclear incident. This study was performed to investigate the report cases of international organizations and foreign countries to set up a domestic control standard for managing radioactive substances that may be contaminated in animal feeds due to the nuclear power plant incident. In addition, an attempt was made to provide a useful reference that can help prepare a domestic control standard, using a coefficient that can consider the transfer into livestock through the intake of radioactive contaminated animal feeds. The standard radioisotopes investigated were confined to radioactive cesium ($^{137+134}Cs$) and iodine ($^{131}I$). Guideline level for the radionuclides was calculated by using the transfer coefficient factor and the maximum daily intake of animal feed provided by IAEA. For example, the maximum daily intake of animal feed was set as $25kg\;d^{-1}$ for dairy cows, $10kg\;d^{-1}$ for beef cattle, $3.0kg\;d^{-1}$ for pigs and $0.15kg\;d^{-1}$ for chickens. The result values for radioactive cesium were calculated as $8,696Bq\;kg^{-1}$, $4,545Bq\;kg^{-1}$, $1,667Bq\;kg^{-1}$ and $2,469Bq\;kg^{-1}$, respectively. The results for radioactive iodine showed the ranges between $741Bq\;kg^{-1}$ and $76,628Bq\;kg^{-1}$. These data can be utilized as a scientific reference for the preparation of a crisis management manual for the emergency control due to nuclear power plant accident in Korea and neighboring country. These results will contribute to establish the safe feed management system at national level as manual for responding the radioactive exposure of agricultural products and animal feeds, which are currently not established.

코로나 시대에 반려동물은 우리에게 많은 위안을 주고, 가족처럼 반려동물을 여기는 펫팸족이 등장하였다. 그리고 젊은 소비자는 자신에게 소비할 금액을 줄여서 반려동물에게 소비하는 패턴을 보이는 펫푸어도 볼 수 있다. 하지만 이러한 시대적인 변화에도 불구하고 펫푸드를 포함한 반려동물 용품 및 화장품은 여전히 수입 의존도가 높고, 국내의 반려동물 화장품 및 용품에 대한 기준이 설정되어 있지 않아 화장품 안전기준 등에 관한 규정에만 의존하고 있는 실정이다. 또한 국내 반려동물 용품 및 화장품에 관한 용어도 아직 정립되지 않은 상태이다. 현재 국내 법률은 반려동물과 관련한 동물보호법 만이 존재하지만 일본에서는 반려동물 사료안전법이 2009년 6월부터 시행되었고, 미국은 연방식품, 의약품, 화장품 관리법에서 반려동물 화장품 및 용품을 담당하고, 동물보호법이 강력한 독일은 식품 및 사료에 대한 다양한 국가 차원의 법규가 있다. 그리고 식품 안전국 웹 사이트에서도 국가 규정을 정밀하게 확인 가능하다. 따라서 본 연구는 국외의 빠르게 성장하고 안정적인 반려동물 산업처럼 국내에서도 반려 동물 산업을 관리하고 개발을 뒷받침 해주는 국가 정책과 환경 등이 반려동물 용품 및 화장품 그 외 다양한 반려동물 관련 산업을 해외시장으로 수출하는데 기초자료로 반드시 필요할 것으로 사료된다.

Hematological and serum biochemical analyses are routinely used to screen dogs for disease and monitor their clinical progression. These values in dogs may be affected by internal factors, such as breed and age, and external factors like environment, diet, and lifestyle. Apparently, subclinical breed-related variations in hematologic and serum biochemical results have been characterized for Bernese Mountain dogs, Alaskan Malamutes, English Setters, and Golden Retrievers. It is possible that some breed-related differences in clinical pathology analyses may reflect evidence of underlying disease and impact clinical decision plan. In this study, we estimated hematologic and serum biochemical parameters in small breed dogs and compared among four different breed dogs. Blood samples were collected from 38 domestic dogs that were 10 Beagles, 9 Malteses, 10 Poodles, and 9 Miniature Schnauzers. In terms of RBC count, Beagle ($7.2{\pm}0.24{\times}10^3cells/{\mu}L$) showed significantly (P<0.05) higher count than other breeds (Maltese, $6.51{\pm}0.25{\times}10^3cells/{\mu}L$; Poodle, $6.35{\pm}0.24{\times}10^3cells/{\mu}L$; and Miniature Schnauzer, $6.35{\pm}0.25{\times}10^3cells/{\mu}L$). For MCV, Miniature Schnauzer ($67.05{\pm}0.84fl$) results were significantly (P<0.05) higher than Beagle with $64.33{\pm}0.8fl$. For cholesterol value, Beagle ($163.3{\pm}9.15mg/dl$) had significantly (P<0.05) higher values than Miniature Schnauzer with $119.12{\pm}9.64mg/dl$. There was no statistically difference among breeds in terms of enzyme markers of liver diseases. In conclusion, data obtained from this study may be valuable as breed-related variability for interpretation of the results in hematologic and serum biochemical analysis among four small breed dogs.

This study was conducted to compare meat quality traits related to the tenderness of longissimus muscles obtained from domestic and imported steers. A total of 12 steers from three breeds were slaughtered, and were graded as quality grade 2. They were composed of 4 Hanwoo and 4 Holstein steers (domestic) as well as 4 Angus steers (imported from Australia and gained for six months in Korea until slaughtered). The longissimus lumborum muscles were separated and were stored at $4^{\circ}C$ for 7 and 14 d. Sarcomere length of Hanwoo was significantly shorter than Holstein and Angus at storage day 14 (p<0.05). The myofibrillar index was significantly lower on Hanwoo than Angus at ageing day 7, and was significantly lower than Holstein and Angus steers at storage day 14 (p<0.05). Total collagen contents of Hanwoo and Angus steers were significantly higher than Holstein on storage day 7 (p<0.05), whereas soluble collagen contents of Holstein were significantly higher than Hanwoo and Angus on storage days 7 and 14 (p<0.05). There was no significant difference in the fatty acid composition of the three breeds (p>0.05). Glutamic acid contents of Hanwoo and Angus steers were higher than those of Holstein steers at ageing day 7 and 14 (p<0.05). The results of this study have shown that there were no dramatic differences between beef from the three breeds that were fattened for 6 months under equal conditions.

Goose hemorrhagic polyomavirus (GHPV) is not a naturally occurring infection in geese in China; however, GHPV infection has been identified in Pekin ducks, a domestic duck species. Herein, we investigated the prevalence of GHPV in five domestic duck species (Liancheng white ducks, Putian black ducks, Shan Sheldrake, Shaoxing duck, and Jinyun Sheldrake) in China. We determined that the Jinyun Sheldrake duck species could be infected by GHPV with no clinical signs, whereas no infection was identified in the other four duck species. We sequenced the complete genome of the Jinyun Sheldrake origin GHPV. Genomic data comparison suggested that GHPVs share a conserved genomic structure, regardless of the host (duck or geese) or region (Asia or Europe). Jinyun Sheldrake origin GHPV genomic characterization and epidemiological studies will increase our understanding of potential heterologous reservoirs of GHPV.

This study was conducted to investigate the carcass characteristics and nutritional composition of longissimus lumborum (LL) muscle of domestic steer beef (Hanwoo and Holstein born and raised in Korea) and imported beef (Angus imported from Australia, raised for about 6 months in Korea). A total of twelve steers (4 steers per each breed and quality grade 2) were slaughtered, LL muscles were separated and stored at $4^{\circ}C$ for 7 days. The pH values of Holstein meat were notably higher than those of Hanwoo, and WHC values were similar between Hanwoo and Holstein, but Angus showed some differences. The WHC of the LL muscle from Hanwoo was better than those from Holstein and Angus when stored for fourteen days. The CIE $a^*$, $b^*$, and $h^0$ values of the LL muscle from Hanwoo were significantly higher than those of Angus at day 7 (p<0.05). Oxymyoglobin and metmyoglobin contents were not significantly different among three breeds at days 7 and 14. In the intra-muscular fat contents, the LL muscle of Hanwoo was significantly higher than Holstein, whereas the moisture and ash contents tended to be lower than the others. In mineral contents, P and Zn contents in the LL muscle of Holstein were higher than the other breeds, and K contents was higher in Hanwoo and Holstein meat than Angus.
