The values of blood composition were analyzed by age, season, and sex from Chejuhorse in Korea. The results obtained were summarized as follow; 1. The values of white blood cell(WBC), packed cell volume(PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration(MCHC) were significantly different between age. The WBC value was decreased with the progress of age and the PCV value was lower in the early age of 1,2 to 3 years than in the higher age of 4 to 5, and over 6 years. 2. The mean value of MCV was increased with the progress of age but the adverse was true in MCHC. 3. In the case of seasons, the values of red blood cell(RBC), WBC, hemoglobin(Hb) PCV, MCV, mean corpuscular hemoglobin(MCH), MCHC, globulin(Glo), albumin/globulin(A/G) ratio, inorganic phosphorus(Pi), cholesterol(Chol), and chlorine(Cl) showed significant differences. The number of RBC was not varied from winter to summer but decreased in autumn. The number of WBC was high in summer and autumn, but low in winter and spring. 4. The values of MCV were high in autumn and winter, but low in spring and summer. 5. The values of MCH and MCHC were similar in spring and summer, but strikingly increased in autumn. 6. The values of Glo and A/G ratio were negatively correlated with the season; The value of A/G ratio was lowest in summer but no differences were observed in spring, autumn and winter. On the other hand, the value of Glo was highest in summer but no differences were observed in spring, autumn, and winter. 7. The values of Pi, Chol, and CI were high in summer and winter, but low in spring and autumn. 8. The values of RBC, MCV, and MCH were significantly different between sex. The value of the RBC count in male was higer than the female, but the adverse is true in MCV, and MCH.

Eurasian black vulture (Aegypius monachus) belongs to family Accipitridae and is a raptor preying small birds and mammals. It is a wintering bird residing from the mid of November to the late of March in Korea. Although Eurasian black vulture population wintering at Korea is gradually increased, the efficient rescue and treatment for injured Eurasian black vultures are still problematic, due to lack of basic data. Therefore, in this survey, to obtain basic resources for establishing more efficient rescue system, we surveyed the number of Eurasian black vultures wintering at Gangwon province, wintering ecology and injury state of Eurasian black vulture. Survey area was Togyo reservoir at Cheorwon, Seonan basin at Yangoo and Wolsong reservoir at Chuncheon from November 2004 to March 2005. From 12 rescued Eurasian black vultures, physical examination, total plasma protein (TPP) and packed cell volume (PCV) were measured. To survey injury state of Eurasian black vultures wintering at Gangwon province, we surveyed the cause, morbidity and mortality from 103 Eurasian black vultures, based on medical records from animal rescue teams. The number of eurasian black vultures were gradually increased from November, peaked at Feburary, then steeply decreased at March. Eurasian black vultures showed the most vigorous activity around 1 PM within a day. In physical examination, mean body weight was $9.6{\pm}1.22kg$, body length was $1130{\pm}45.4mm$. No statistically significant difference in body weight and length between male and female eurasian black vultures was observed. Mean PCV was $40.2{\pm}2.7%$, while mean TPP was $5.86{\pm}0.8mg/dl$. The most common cause of injury and mortality was intoxication, while that of morbidity was fatigue.

A study was conducted on the effects of ploughing on physiological responses of male and female Bali-cattle. A $2{\times}2{\times}6{\times}8$ factorial design (2 seasons, 2 sexes, 6 days and 8 consecutive time of measurements every 30 minutes) was employed. Responses during the cool/humid season were lower than hot/dry; respiration rate (RR) was 52 vs 75/min, rectal temperature(RT) was 39.1 vs $39.5^{\circ}C$ and skin temperature (ST) was 37.1 vs $37.6^{\circ}C$. Within sexes, males were less tolerant than females in that their RR (66 vs 61 breath/min), RT (39.4 vs $39.2^{\circ}C$) and ST (37.6 vs $37.1^{\circ}C$) were each higher than females during work. With increasing time, during the average 2.5 h working period gradual increases in RR, RT and ST were recorded and the overall increases of 84 breath/min, $1.9^{\circ}C$ and $13.8^{\circ}C$ respectively (p < 0.001). Packed cell volume (PCV) data indicated significant difference between sexes, time and season (p < 0.001, p < 0.05 and p < 0.001 respectively). Within time (before and after 2.5 h working) the PCV decreased from 27.4 to 25.6%.

The purpose of this investigation was to study the hematological response of Saudi Arabian Baladi fowl to protein rearing regimens. Males and females were subjected to the following 4 protein rearing regimens: conventional, C; reverse protein, RP; 2 single-stage low protein, $SS_1$ and $SS_2$ using 15% and 12% CP diets, respectively. Regimen effect was highly significant ($$p{\leq_-}.01$$) on BW, PCY, TP and U-Ac and significant ($$p{\leq_-}.05$$) on TL. Serum chol levels were not affected by regimen. In general $SS_{2}$ birds showed the lowest values for all parameters studied, except for PCV. However, the differences were not significant in each case. Age and sex effects were highly significant ($$p{\leq_-}.01$$) for all parameters, however, the regimen X sex interaction was not significant except for PCV. Regimen X age interaction, on the other hand, was highly significant ($$p{\leq_-}.01$$) only for BW, TP and U-Ac concentrations. The data may suggest that low levels of protein in the rearing regimen is an important factor influencing levels of the blood parameters studied. The data also indicate a lack of clear relationship between hen-day egg production and the blood parameters studied.

The purpose of this study was to investigate seroprevalence of porcine respiratory diseases including porcine reproductive and respiratory syndrome (PRRS), porcine circovirus-2 (PCV-2), Mycoplasma hyopneumonia (MH), Pasteurella multocisa A (PMA), Haemophilus parasuis (HP), Actinobacillus pleuropneumonia type 2 (APP2), and Actinobacillus pleuropneumonia type 5 (APP5) in Jeonbuk state by enzyme-linked immunosorbent assay (ELISA). Total 5488 samples collected from four breeding pig farms and 55 commercial pig farms were tested. The overall seroprevalence of PCV-2, APP2, APP5, PMA, and HP was higher in breeding pig farms than in commercial pig farms, with higher antibody positivity rate (more than 97%) in breeding pig farms. Seroprevalence of MH or PRRS were 68.4% and 48.7% or 79.4% and 58.2% in commercial pig farms or breeding pig farms, respectively. The overall seroprevalence of the porcine respiratory diseases tested in this study varied depending on the age group of pigs, with the 40-day-old pig group showing the lowest seroprevalence and mean S/P titer ratio.

Respiratory diseases are common in swine industry and have great economic importance. Respiratory disorders cause substantial losses to the swine industry. Losses associated with respiratory disease vary considerably between herds and seasons. In a survey was carry out to investigate the lesion of red internal organs in slaughtered pigs and provided assistant data which are useful for each farm. From november 2012 to december 2013, 1,680 pigs out of 84 farms were sampled in Jeonbuk province. Gross lesions such as swine enzootic pneumonia (SEP), pleuritis, pleuropneumonia, pericarditis, liver milk spot were examined for the pigs. Overall prevalence of SEP was 55.7%. According to season, the incidence occurred higher in fall than winter, spring, and summer. The mean SEP score was 0.91, the highest incidence occurred in fall. The prevalence of pleuropneumonia, pleuritis, pericarditis, and milk spot was 36.4%, 49.7%, 2.3%, and 8.8%, respectively. The positive rate of PRRS and PCV2 was 2.9% and 70.0% by PCR analysis.

Effect of the two-stage operation and cell concentration on indirubin production was investigated using bioreactor culture of Polygonum tinctorium. Two-stage culture was operated successfully for 110 days without any adverse effects on continuous indirubin production. Maximum indirubin concentration was found to be at 80 mg/bioreactor. Initial cell concentration significantly affected indirubin production. The indirubin production at 29.2% PCV was improved by 845%, compared to that at 5% PCV. For high-density bioreactor culture of P. tinctorium, a maximum production rate of 10.2 mg indirubin/L day was obtained. Indirubin recovery for bioreactor operation was also examined using XAD-2, XAD-4, XAD-7, and solid silicon. XAD-4 was 1.6-fold more effective than that for solid silicon in indirubin recovery.

The prevalence of potentially xenozoonotic viruses in the reproductive tract of female pigs in Korea was investigated by polymerase chain reaction (PCR). These viruses include porcine endogenous retrovirus (PERV), porcine reproductive and respiratory syndrome virus (PRRSV), swine hepatitis E virus (SHEV), porcine lymphotropic herpesvirus (PLHV), and porcine circovirus type 2 (PCV-2). Histopathological examination and PCR analysis were conducted using the ovaries of 70 slaughtered pigs that were collected from 14 farms in Jeju. Histopathologically, infiltrations of mononuclear inflammatory cells around the thick-walled coiled vessels in the ovarian medulla were observed in 15 cases. Based on the PCR method, PERV, PLHV, PRRSV, SHEV, and PCV-2 were detected in 69 (98.6%), 35 (50%), 5 (7.1%), 4 (5.7%), and 1 sample (1.4%), respectively. These results suggest that PERV and PLHV are the major xenozoonotic viruses in the porcine ovary. This study should aid in the development of a monitoring protocol for potential xenozoonotic agents and in the production of germ-free pigs for xenotransplantation.
