Local treatment of interdigital phlegmon (footrot) by the regional intravenous administration of Tylosin in cows

Introduction

Interdigital phlegmon (IP) or footrot is a common infectious disease in bovine. It produces lameness in dairy cattle and feedlots. In some severe cases, the animal does not respond favourably to the parenteral administration of antibiotics such as tylosin or ceftiofur. Possibly, the farmer does not pay enough attention and treats without veterinary supervision. There are some studies conducted with the intravenous regional administration of quinolones in IP treatment. (Varsano et al., 2015.; Celani et al., 2017). Due to the current EU regulation on the use of antibiotics, quinolones and cephalosporines (category B) can only be used in the case of laboratory tests that justify their use. The hypothesis of the study is that IP could be treated by regional intravenous tylosin rather than the use of quinolones.

Objective

The objective of the study was to evaluate the efficacy of IP treatment by the regional intravenous administration of tylosin and a tourniquet for 3 consecutive days. [...]
