For the purpose to increase productivities of livestock the present investigations were undertaken in order to clarify the clinical and suclinical status of Korean native cattle, dairy cattle(holstein) and Korean native goat. 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) and 142 Korean native goat rearing at Chonbuk area and analyzed for clinical, serum chemical, hematological and urinary findings. In addition, we were examined the infection rate of theileriosis, internal parasite 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. Abnormally 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 and 13.36% of Korean native goat. Adult Korean native cattle and adult dairy cattle which showed hematologically anemia were 4.95% and 19.43% respectively, but Korean native calf and dairy calf showed normal. Adult Korean native cattle, adult dairy cattle, Korean native calf and dairy calf which showed normal serum protein level 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 range. These abnormally decreased serum protein values mean the shortage of antibody, and these have a possibility to occurs 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 of 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 for 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 parsite were as follows; adult Korean native cattle: 21.2%, Korean native calf: 8.0%, adult dairy cattle: 67.8% and Korean native goat: 81.5%. The estimated economical loss caused by internal parasites infection were 1,120,855,837 won in Korean native calf, 4,994,959,405 won in adult Korean native cattle, 3,334,751,066 won in adult holstein, and the total loss amount to 9,450,566,308 won. The infection rate of theileriosis were 1.4% in Korean native cattle and 6.6% in dairy cattle. The presumed economical loss by T. sergenti infection were 154,408,482 won in Korean native cattle and 171,577,237 won in dairy cattle rearing at Chonbuk area. The infection rate of ringworm were 0.5% in Korean native cattle, 0.9% adult dairy cattle and 7.7% in dairy calf. The presumed economical loss by dermatomycophyte were 12,061,532 won in Korean native cattle, 16,895,403 won in dairy cattle, and the total estimated loss amount to 28,955,935 won a year in Chonbuk area. |
