A automated noncontact weight system for pigs consisted of a CCD-type video camera and 10 photo sensors connected to a computer. In the experiment 20 pigs(Large Yorkshire $\times$ Landrace breed) weighing from 95kg to 115kg were used. Pig's original image data was transformed to a binary image an image excluding head and tail portion from the whole binary image and the area of pig was calculated. Then pig's volume was calculated by multiplying the area by the body hight measured with photo sensors. The correlation equation between the above volume(x) and pig's weight was y=0.0007 x -9.2152($R^2$=0.9965) Performance of a automated noncontact weighing system for pigs was tested with this equation. The results showed $\pm$0.65kg average error and 1.63kg maximum error. It was concluded that performance of a automated noncontact weighing system is excellent.

A monitoring and the forecasting system for the swine delivery was developed using CCD camera multi-function board microphone and data-recorder equipped on a personal computer. For the swine delivery monitoring and forecasting factors four factors were selected such as genitalia swine body shape breast color and sound. Image of physical variation of body shape, shape and color of genitalia area and color of breast of pregnant sow were grabbed using the CCD color camera and multi-function board and variation of voice of pregnant sow was acquired using microphone and data recorder. Acquired information of image and voice were analyzed using a custom developed algorithm and program. The result of the forecasting efficiency of swine delivery was 89%, 71% and 100% using the variation of genitalia are the body shape and the voice of pregnant sow. respectively. The efficiency of image processing was 100% for the delivery detection when the piglet was delivered half of its body from genitalia of pregnant sow, The monitoring and forecasting system informed the estimated time of the delivery of swine to a farm manager immediately if an estimated and established time set by the farm manager was the same and/or the estimated time ws earlier than the established time and the system detected the delivery.

The number of dairy cows diagnosed and treated at Hyup-dong Animal Hospital from July 1983 to June 1984 was amounted to 3,073 heads of Holstein breed and the result of analysis of diseases was as follows : 1. In the topographic diagnostic categories, 41.23% of all cases involved the urogenital system and were observed most prominent. Next were digestive system (22.10%), general and regional (14.55 %), respiratory system (8.20%) and musculoskeletal system (7.06%) in decreasing order. 2. In urogenital system 50.20% of all diagnosis involved metritis and this were most prominent disease. Next were repeat breeder(15.31%), retained placenta (12.79%) and ovary disfunction(9.40 %) in decreasing order. 3. In digestive system 36.82% of all diagnosis involved enteritis and were most prominent. Next were abomasal displacement (29.31%), lumen indigestion (20.32%) and lumen bloat (9.57%) in decreasing order 4. In general and regional diseases, 52.80% of all diagnosis involved ketosis and were most prominent. Next were milk fever (25.50%), downer cow (5.82%) and omphalitis (4.47%) in decreasing order. 5. In respiratory system, 82.54% of all diagnosis involved upper respiratory tract infections and were most prominent. Next were pneumonia (15.87%). 6. In musculoskeletal system, 49.31% of all diagnosis involved foot rot and were most prominent. 7. In milk secreting system, 61.64% of all diagnosis involved mastitis and ere most prominent. Next were stenosis of teat canal (16.35%). 8. Among the individual disease entities, endometritis marked 20.7%, enteritis 8.13%, ketosis 7.68% upper respiratory tract infection 6.77%, repeat bheeder 6.31%, retained placenta 5.27%, abomasal displacement 4.69%, and lumen impaction 4.49%, respectively of total 3,073 cases in decreasing order.
