Safe management system for pig production with treatment of periodontal diseases

慢性牙周炎的特征是慢性菌斑和结石堆积以及牙周炎。在人类中，牙周炎与糖尿病等慢性疾病有关。而孕妇的牙周病可能会增加早产和低出生体重儿的风险。在这项研究中，我们调查了锯子中的牙周病及其产仔性能。所有年龄较大的母猪都表现为牙周炎，没有牙槽骨吸收。而患牙周炎的母猪血浆肿瘤坏死因子-α水平较高，窝仔存活率较低。几头较年轻的母猪也表现出牙周炎。因此，应建立生猪生产中牙周病的管理制度。

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.
