  • Sixteen ruminally cannulated Korean native steers (Hanwoo; $626.2\pm47.72$ kg) were used to investigate the effects of polyclonal antibodies against abdominal (AAb) and subcutaneous adipocyte membrane proteins (SAb) on ruminal fermentation patterns and blood metabolites. The body weight (BW) of Hanwoo was decreased 2-weeks after AAb and SAb injection, BW reduction was also observed in control and non-immunized serum groups, indicating that stress induced by other factors (e.g. blood sampling etc.) rather than antibodies injection may affect the BW reduction. Antibodies treatment did not affect (P > 0.05) rumen pH, volatile fatty acids and ammonia-N concentration. The ranges were similar with typical ranges of those in Hanwoo. Compared with control, blood urea N concentration was decreased in AAb group and increased (P < 0.05) in SAb group before antibodies treatment. However, none of the groups were significantly (P > 0.05) affected at 2- or 4-weeks after the treatment. Concentration of plasma glucose in the non-immunized serum group was significantly higher (P < 0.05) than the other groups at 0-week after treatment. However, antibodies treatment did not affect the concentration of plasma glucose. Concentration of plasma triglyceride showed no difference (P > 0.05) between the groups and ranged from 11.4 to 19.9 mg/dl, which is the perfect range of plasma triglyceride of Hanwoo fed concentrate based diets. In conclusion, these results may indicate that the present AAb and SAb have safety in nutritional physiological metabolism in Hanwoo. Further study on in vivo fat reduction of the antibodies against abdominal and subcutaneous adipocytes PMPs of Hanwoo is required for inedible fat-reduced high quality beef production.

  • Objectives: The purpose of this study is to analyze agricultural accident and disease using statistical data and materials about National Survey for Health & Nutrition in 2001 and to provide fundamental materials for studies about farmers' health and safety, decision of priority about research and policy. Results: Diagnosed chronic disease prevalence is 72.4% in farmer/fisher group, 49.8% in non farmer/fisher group. The chronic disease prevalence of musculoskeletal disease, circulatory disease, and gastroenteric disease is 46.5%, 18.2%, and 17.9% in farmer/fisher group respectively. The prevalence of musculoskeletal disease in farmer/fisher is 2.4 times higher than non farmer/fisher. This result shows that it need to evaluation for risk factors of musculoskeletal disease preferentially. Lifetime accident/poisoning rate is 18.2% In farmer/fisher group and 13.3% in non farmer/fisher group. The types of accidents were fracture>sprain>contusion and the reasons of accidents were traffic accident>falling/sliding. Conclusions: "Bad or very bad" response of farmer/fisher is almost 2 times higher than non farmer/fisher group. The rate of smoking and no exercising in farmer/fisher group is higher than non farmer/fisher group.
