From 2,373 slaughtered pigs examined, 1,899 of them had visible evidence of pulmonary lesion. The lungs with pulmonary lesion were examined by grossly, histopathological technique to investigate the prevalence accordint to season, severity ofpulmonary lesion, types of the pneumonia and relationship between rearing management and prevalence of pulmonary lesion. The results were as follows: 1. Prevalence of pneumonia according to season was 72.3 % to 85.9% and the higher prevalence was in winter. 2. In the severity of pulmonary lesion, rates mild, moderate and severe lesions were 38.3%, 47.0% and 14.7%, respectively. Prevalence of mild lesion was the highest in autumn. Prevalence of moderate and severe lesions was the hihgest in winter. 3. In the type of pneumonia, rates of interstitial pneumonia and bronchopneumonia fibrinous pneumonia were 23.6%, 13.0%, and 3.4%, respectively. Prevalence of interstitial pneumonia was high in spring and autumn while that of broncho-pneumonia and fibrinous pneumonia was high in winter and summer, respectively. 4. In relationship of pulmonary lesions according to severityo fpulmonary lesion and types of pneumonia, similarity was observed in prevalence of mild lesion and bronchopneumonia.

This study surveyed the prevalence of traumatic reticular diseases (TRD) of slaughter cattle in Korea, the typology of the causative foreign bodies and the effects on beef quality and carcass weight. The overall prevalence of TRD in 3,121 slaughter cattle was 5.5%. However, the prevalence was significantly higher in Korea indigenous cattle Hanwoo (5.8%, p less than 0.05) and female cattle (20.75%, p less than 0.001). The prevalence significantly increased in aged cattle (p less than 0.001). Major lesions related to foreign bodies were reticulitis (96%) and peritonitis (86%). Most causative foreign bodies were made of iron including nails, wires, steel rods, screw nails, and syringe needles. Cattle affected with TRD produced significantly lower grade quality of beef compared to normal cattle (p less than 0.0001), but TRD did not affect carcass weight. The data will be useful in the management of TRD, with the aim of increasing beef productivity in Korea.

In korea, burial is the most common method of disposing animal carcasses culled due to brucellosis infection. However, burial has many disadvantages such as shortage of appropriate burial sites, possibile pollution of ground water supply, and negative view of the public. In this study, we have reviewed 3 legal methods for disposing bovine carcasses, which are burial, incineration, and rendering. We also described the overall process, advantages and disadvantages, and required costs for each method. About 75% of bovine brucellosis outbreak farms had less than 3 reactors, and in our study, rendering required the least amount of cost for farms with a small number of reactors (1-3 heads). Our findings suggest that the use of rendering should be encouraged for farms with bovine brucellosis and other methods considered only if rendering is inappropriate.

In the conditions of the Republic of Belarus there were analyzed high productive traits of meaty calves and cross breeds bred in accordance with a system cow-calf, as well as the possibilities of using veal meat obtained in ecologically safe areas for infant food production. At the age of 6,5-7 months the weight of fresh carcass of bull-calves of sharolez breed in comparison with aberdin-angus х black-motley herdmates was on 41,6 kg (Р less than 0,001) higher, carcass yield and slaughter yield – on 13,8% (Р less than 0,001) and 13,6% (Р less than 0,001), respectively. The fat content in sharolez meat was 4,9% against 8,9%; protein - 21,9% against 18,8%. The black-motley suckling bull-calves surpassed their herdmates which were grown up by technology of dairy cattle breeding at the age of 6-6,5 months according to indexes of weight of fresh carcass - on 16,3 kg or 21,7% (Р less than 0,01); according to indexes in a slaughter yield - on 16,6% (Р less than 0,001); and according to indexes meat flesh in a carcass - on 1,5%. According to quality indexes, amino acid structure, acceptable concentration of toxic elements content, pesticides, antibiotics, radionuclides and other harmful substances the veal meat of calves which were bred on a system a cow-calve in ecologically pure zones proved to be important meat raw materials to produce infant food products.
