Excessive inflammation, oxidative stress, and alterations in copper and zinc can accompany pneumonia. As these micro-nutrients play crucial roles in immune function and anti-oxidant defence, modulating their levels may influence the disease progression. This study aimed to investigate the effects of different therapeutic regimens on copper and zinc status in lambs with pneumonia. Twenty lambs with pneumonia were randomly assigned to four treatment groups: oxytetracycline and tylosin (OT), OT plus vitamin B1 (OTVB1), OT plus vitamin C (OTVC), and OT plus vitamin B1 and vitamin C (OTVB1C). A control group received only distilled water. Blood samples were collected on days 1, 3, 6, and 14 for subsequent assessment of plasma copper and zinc concentrations. While the control group maintained stable levels, the pneumonic groups exhibited varying degrees of changes. Plasma copper concentrations increased significantly in all pneumonic groups compared to the control group throughout the study. The OT and OTVB1C groups had the highest number of lambs with increased copper level. Plasma zinc concentrations decreased significantly in the OT and OTVB1 groups, with the lowest levels in the OTVB1 group on day 3. The OTVC group mirrored the control group with stable levels. The OTVB1C group, compared to the other groups, showed a more persistent reduction. These findings suggest that the effects of the various treatment regimens on plasma copper and zinc levels may be complex and time-dependent.</p>","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"16 6","pages":"331-338"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12295534/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144733622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
