Abstract
We are aim to evaluate antimicrobial effects of the extract of Galla rhois (GR) on the health status and performance of growing and finishing pigs. This study was conducted on the growing and finishing pigs (n = 200) for 130 days in a swine husbandry. The animals were divided with two groups; GR treated group (n = 100) and commercial diet feeding group (n = 100). GR treated animals had provided with commercial diet adding the extract of GR as 0.2%. During the study period, we compared clinical signs, weight increase rate, diet consumption amount, fecal scores, gross findings, necropsy findings, histopathological findings between the treated group and non treated group. After necropsy, bacteria isolation and PCR analysis were conducted with the clinical samples. As the results of this long-term clinical trial, GR showed the antimicrobial effects on respiratory disease and diarrhea. We were identified that GR had the anti-bacterial and anti-viral effects.
