Present investigations were undertaken in order to clarify the clinical status of Korean native cattle and dairy cattle(holstein). Blood, Feces and urine samples were collected from 247 Korean native cattle(222 adult and 25 calf), 224 dairy cattle(211 adult and 13 calf) at Chonbuk area and analyzed for clinical, serum chemical, hematological and urinary findings. In addition, we were examined the infection rate of Theileriosis, internal patasite and ring worm. The mean value for each component was calculated by statistical analysis using Excel computer program. From these investigations the following results were obtained. The mean values for RBC, PCV and etc in 433 adult cow(Korean native cattle and dairy cattle) were similar with other reports. But the mean values for MCHC of all species were lower than normal. Adult Korean native cattle and adult dairy cattle which showed hematologically normal levels were only 9.01% and 9.48%, respectively. Ahnormally high values for PCV, RBC and Hb were recorded in 7.66% of adult Korean native cattle, 20% of Korean native calf, 15.38% of dairy calf. Adult Korean native cattle and adult dairy cattle which showed hematologically anemia were 4.95% and 19.43% respectively, but all in Korean native calf and dairy calf showed normal values. Adult Korean native cattle, adult dairy cattle, Korean native calf and dairy calf which showed normal serum protein level were 84.0%, 90.8%, 50% and 44.4%, respectively. In present investigations, 50% of Korean native calf and 55.6% of dairy calf were decreased serum protein values under normal range. These abnormally decreased serum protein values mean the shortage of antibody, and these have a possibility to occrus to pneumonia and diarrhea. From these results, the economical loss caused by pneumonia was calculated as 124, 038, 833 won in the KNC and 742, 703, 430 won in the dairy calf rearing in Chonbuk area. Calculated economical loss caused by enteritis was 56, 658, 690 won in Korean native cattle. 476, 775, 799 won in dairy calf and the total loss amount to 533, 434, 488 won in Chonbuk area. Abnormally high values($21.7{\pm}4.0mg/dl) for serum calcium were recorded 49.6% in dairy cattle. The mean values of serum total cholesterol were $170.8{\pm}99.8mg/dl in Korean native cattle, $196.0{\pm}40.6mg/dl$ in Korean native calf, $202.9{\pm}86.0mg/dl$ in adult dairy cattle and $289.4{\pm}97.5mg/dl$ in dairy calf. The infection rate of internal parasite were as follows; adult Korean native cattle:21.2%, Korean native calf:80%, adult dairy cattle:67.8%.

This study was conducted to fine the adaptatbility of Korean Native Cattle lacking in the resistance ability to Theileriosis being occured by ticks born parasites in Cheju Island. Data used in this study were collected from none-treated and treated Thpileria sergenti blood vaccine to Korean Native Cattle, Cheju Native Cattle and Cheju Native CattlexBrahman crossbreds during the grazing season in 1988. The parasitemia level of Theileria sergenti in artificial immunized Korean Native Cattle were fewer than none-treated Korean Cattle's, due to immunizing effects. the RBC and PCV reduction were prevented, and average daily gain's 0.25kg in artificial immunized Korean Native Cattle was higher than those of 0.20kg in none-treated. The mortality numbers were one in artificial immunized Korean Native Cattle and four in none-treated Korean Native Cattle. The resistance ability of Theileriosis of Korean Native Cattle was the weakest and Cheju Native Cattle×Brah-man crossbred was the strongest among the breeds.

Drug-metabolizing activities of Korean native cattle and swine were investigated from viewpoints of the cytochrome P-450's level, their dependent mixed function oxidase activities, the reactive oxygen species formation and cytosolic enzyme acitivities from each liver homogenates. Level of cytochrome P-450 in the liver microsome of Korean native cattle was $0.28{\pm}0.05nmole/mg$ and that in pigs $0.35{\pm}0.03nmole/mg$. Level of cytochrome $b_5$ of Korean native cattle was $0.24{\pm}0.06nmole/mg$, and that of pigs $0.2{\pm}0.05nmole/mg$, showing no difference between two species. NADPH P-450 reductase were higher in Korean native cattle ($58.3{\pm}5.3nmole/mg/min$) than in pigs ($29.9{\pm}3.8nmole/mg/min$)(p<0.01). The activities of cytochrome P-450 dependent monooxygenases such as ethoxyresorufin O-deethylase (cattle, $96.5{\pm}12.5nmole/mg/min$ ; pigs, $13.6{\pm}2.1nmole/mg/min$), N-benzphetamine N-demethylase (cattle, $5.23{\pm}0.82nmole/mg/min$ ; pigs, $0.76{\pm}0.3nmole/mg/min$) and aniline hydroxylase (cattle, $0.95{\pm}0.1nmole/mg/min$ ; pigs, $0.33{\pm}0.08nmole/mg/min$) were much higher in Korean native cattle than in swine(p<0.01). However, the activity of testosterone $7{\alpha}$-hydroxylase was higher in swine ($90.4{\pm}1.2nmole/mg/min$) than cattle (cattle, $32.8{\pm}1.2nmole/mg/min$). Interestingly, testosterone $16{\alpha}$-hydroxylase, a marker enzyme for P-450 IIA was not detected in both animal species. These results suggest that Korean native cattle and pigs have high contents of P-450 IA1 and P-450 IIIA. Total sulfhydryl compound (cattle, $10.3{\pm}1.1nmole/mg$ ; Pigs, $14.5{\pm}1.8nmole/mg$) and glutathione related enzymes except glutathione reductase (cattle, $38.1{\pm}7.9nmole/mg/min$; swine, $22{\pm}3.6nmole/mg/min$) showed higher levels in swine than in Korean native cattle. Superoxide dismutase (cattle, $7.64{\pm}0.84nmole/mg/min$ ; pigs, $4.47{\pm}0.94nmole/mg/min$) and catalase (cattle, $30.4{\pm}3.7nmole/mg/min$ ; pigs, $17.2{\pm}1.8nmole/mg/min$) were remarkably higher in Korean native cattle than in swine (p<0.05).

Sperm cryopreservation is an important method of assisted reproductive techniques and storing genetic resources. It plays a vital role in genetic improvement, livestock industrial preservation of endangered species, and clinical practice. Consequently, the cryopreservation technique is well organized through various studies, especially on Korean native cattle (Hanwoo). However, the cryopreservation technique of Korean native brindled cattle, which is one of the native cattle species in Korea, is not well organized. Therefore, it is necessary to develop a Supplementary Table technique for the cryopreservation of Korean native brindled cattle. For this purpose, it is important to first evaluate the quality of the currently produced cryopreserved sperm of Korean native brindled cattle. In this study, we randomly selected 72 individual Korean native brindled cattle semen samples collected from 8 different region research centers and used them to evaluate sperm functions. We focused on the quality evaluation of cryopreserved Korean native brindled cattle semen following the measurement of motion kinematics, capacitation status, intracellular ATP level, sperm motility, and cell viability. Then, the values of each of the eight groups were derived from various sperm parameters of nine individual samples, including sperm motility, kinematics, cellular motility, and intracellular ATP levels, which were used to compare and evaluate sperm function. Overall, differences in various sperm parameters were observed between most of the research centers. Particularly, the deviations of motility and motion kinematics were high according to the sample. Therefore, we suggest that it is necessary to develop a standard method for the cryopreservation of Korean native brindled cattle semen. We also suggest the need for sperm quality evaluation of the cryopreserved semen of Korean native brindled cattle before using artificial insemination to attain a high fertility rate.

곽호,김기영,김동균,이상정 한국지식정보기술학회 2015 한국지식정보기술학회 논문지 Vol.10 No.2

Existing estrus detection products operation inconvenience, due to the reliability of the device degradation problems estrus detection probability is lower. In addition, most existing studies was the study of estrus detection of milk cows in large-scale farms studies on Korean Native Cattle farms was not realized. In this paper, discerned using a 3-axis accelerometer to determine the estrus state of Korean Native Cattle. The Korea Native Cattle estrus detection system proposed in this paper consists of these, the three-axis acceleration sensor, sensor network uses Zigbee communication, a base station, field server and database servers. When there is no movement the value of the three-axis acceleration sensor is 1000 due to gravity, the acceleration sensor attached to the cattle’s neck causes a feeble change even though there is no movement of cattle. In this paper, due to the no activity of Korean Native Cattle, censed weak values of sensor are filtered out. In the experiment the sensor data acquisition activities that occur during the actual targeting Cattles at the Cattle farmer by the three-axis acceleration sensor X, Y, Z-axis values analyzed through SVM algorithm output’s one representative value and ISVM algorithm which output integral average. In addition, to determine Korean Native Cattle’s estrus time, activity data collected and compared by 3 hours, 6 hours integral. ISVM algorithm was validated by experimental results that the appropriate algorithm for the Korean Native Cattle’s activity analysis.

The characterization of the MHC of domestic animals may constitute a first step towards increasing the efficiency of food production through improved disease resistance. In order to study the role of the MHC in regulating immune response it is first necessary to identify the different MHC alleles. In this research we try to investigate the possible associations between BoLA of Korean native cattles and infectious cattle disease. For this purpose we used one approach, serology. The results were summarized as follows : 1. Korean native cattle's lymphocyte reacted with alloantisera which recognized seven official BoLA allele. Korean native cattle's lymphocytes were reacted same as European breeds(especially with 673/3(W20)). 2. Korean native cattle's lymphocytes reacted with alloantisera 773/2, 673/3, 638/3, 773/3, 602/2, 639/2 and 639/3 at high reaction frequency. But alloantisera 642/1 was not expressed on Korean native cattle. If this allele, recognized by alloantisera(642/1), officially certificate In BoLA workshop it will be characterization factor of Korean native cattle. 3. According to cellular similarity index, we can presume on genetic relativity which has no family relationship.

Telomeres at the end of the eukaryotic chromosomes consist of tandem repeats of (TTAGGG)n DNA sequence and shelter in protein complex. Telomeres have the essential functions in chromosome stability and genome integrity and are hence related to cell senescence and cancer. Stripped, Black and White Cattle (Endangered Korean Native Cattle) characterized by their coat color, live in the Korean peninsula. However, they are endangered, with very small populations remaining. To investigate the karyotypic pattern of chromosome and also to quantify the amount of telomeric DNA was carried out from the traditional Korean beef cattle species, HanWoo and endangered cattle bull. We quantified the amount of telomeric DNA by the Quantitative-Fluorescence in situ Hybridization (Q-FISH) technique using the telomeric DNA probe and chromosome analysis of lymphocytes was carried out using GTG-banding in 9 bull at age of 18 months. In results, we found that the normal (60, XY) male karyotype were detected in metaphase chromosomes from korean native cattle including Hanwoo, Stripped, Black and White cattle, respectively. In addition, there were no significant differences in the relative amount of telomeric DNA among the korean cattle bull. However, the relative amount of telomeric DNA of Hanwoo was slightly higher than that of White cattle. In conclusion, this study reported karytype and the amount of telomeric DNA which could serve as baseline information for comparison in conditions of physiological and health status of endangered Korean native cattle. Although we have no definitive explanations as to why this occurs, further investigations are needed to continue investigation of these animals throughout their life spans.

글로벌화에 따른 로컬 축산업의 변동- 한우의 사회적 생산과 전략적 산업화를 중심으로

김나리,박경환 제주대학교 교육과학연구소 2016 교육과학연구 Vol.18 No.2

In many thoughts on contemporary globalization process, the ‘local’ has been often considered something pre-existing, conventional, natural, essential, and familiar, while the ‘global’ is situated as the anti-thesis of the local. In this context, Korean native cattle in South Korea have been regarded as natural, local, and traditional for many consumers. As contemporary Korean native cattle are more raised within the industrial production system, its biological attributes are socioeconomically recoded. In addition, as global standards on security and safety have been expanding, the production system of Korean native cattle are rapidly institutionalized. In this context, new local strategies, which are highly commercialized, are being developed for securing domestic beef market. Thus, Korean native cattle are becoming a ‘discursive construct’ in which various social and economic meanings are embodied. By employing Foucauldian discourse analysis, this paper aims at tracking the ways in which Korean native cattle have embodied institutionalized discourses involved in these global and local transitions. Conclusively, through this investigation, this paper reveals how knowledge system and its institutionalization involve the industrial production of Korean native cattle. 글로벌화에 의해 상품 사슬의 지리적 복잡성이 증대됨에 따라 ‘로컬한 것’에 대한 인식과 이해가 점차 중요한 과제로 부상하고 있다. 흔히 한우는 순수하고 전통적인 우리 것이라는 의미에서 ‘로컬한 것’으로 간주되어 왔다. 그러나 한우는 매우 산업적인 생산 시스템에서 ‘구성’되고 있고, 이에 따라 본연의 생물학적 속성이 사회·경제적 측면에서 새롭게 재편되고 있다. 또한, 글로벌화에 따른 표준화 현상으로 안전이나 위생과 관련된 글로벌 스탠더드가 확대됨에 따라 한우 생산 과정도 이러한 규제를 받으며 빠르게 제도화되고 있다. 또한, 쇠고기 시장 개방에 따른 국내 한우업계의 대응 전략은 한우를 단지 ‘소’라는 자연적 생물을 넘어 각종 규준과 사회적 의미가 내포된 전략적 산업화의 상품인 담론적 구성물로 만들고 있다. 본 논문은 푸코의 담론 분석을 통해 한우 담론을 추적하고 그에 내포된 의미를 발견하고자 하였으며, 한우 담론을 구성하는 지식 체계, 이의 산업화와 제도화 과정, 담론의 특징을 드러내고자 하였다. 한우를 매개로 한 로컬 축산업의 지리에 대한 이해는 현행의 국제이해교육 및 글로벌화에 대한 이해를 제고하는 데에 기여할 수 있다.
