| Research Abstract |
Chronic periodontitis is characterized by chronic plaque and calculus accumulation and gingival inflammation. In human, periodontitis is associated with chronic diseases such as diabetes. And periodontal disease in pregnant women may increase the risk for premature delivery and low birth weight infants. In this research, we investigated periodontal diseases in saws and their litter performance. All older sows manifested periodontitis without resorption of the alveolar bone. However, sows manifested periodontitis showed higher plasma TNF-a and their litter survival rates were low. Several younger sows also manifested periodontitis. Growth rate of their litters were low.
We concluded that management system for periodontal diseases in swine production should be established.
