VILLARROEL NERI, Regino et al. Efficacy and efficiency from using intramuscular tylosine on the therapy of bovine hoof lesions. Rev. Cient. (Maracaibo) [online]. 2006, vol.16, n.5, pp.466-471. ISSN 0798-2259.

With the goal to determine the efficacy and efficiency of the systemic antibiotherapy on the acute and sub acute hoof lesions a research was developed in two milking farms at Zulia state, Venezuela. In a period within July and August 2000, 29 cows were evaluated to determine the degree of lameness and to classify the different lesions founds at the digits. The experimental animals were group in three lots: two experimental groups (treated either intramuscular or local) and one control group. As far as it was possible the three groups were maintained with the same challenge in relation of lameness and lesions in each one. The clinical data were recorded individually. The established method allowed to monitor the animals at 0; 48: 120 h with the goal to determine the efficacy and efficiency of each treatment supported by two variable responds: grade of lameness (GC) and the clinical characteristics of lesions (CL). The results showed that both treatments were able to diminish the degree of lameness (GC) and over the clinical characteristics of lesions (CL) of experimental animals when it was compared with the control group (P < 0.05). However in relation to efficiency (treatment cost), the use of local treatment was better than the systemic treatment. Therefore its promotion and application is recommended for the treatment of hoof lesions
