Control of bovine papillomatosis using copper earring and chlorobutanol with immune activator, Jinotega 2018

Abstract

The research was conducted at Hacienda Hungría, Jinotega, Nicaragua, in a group with 18 calves affected with bovine papillomatosis (BPV), a completely randomized design was applied to evaluate two treatments (T1 - copper arete, yatrénic acid and casein, T2 - chlorobutanol, yatrénic acid and casein) in three types of papillomas with three replicates of six animals, under controlled conditions. The number and type of papillomas disappearing per treatment, the hematocrit behavior and the duration of treatment were considered. The data were transformed with natural logarithm and processed with the statistical program InfoStat 1.1, using Anova and Tukey’s separation test; for the hematocrit variable, the T-Student test was used. With copper earring there was a greater decrease in the number of papillomas and time in days; no significant difference was found between treatments. Between initial and final hematocrit there was a significant difference (p<0.05), with copper arete there were lower levels. Both treatments control bovine papillomatosis without considering the type according to its form. The treatment with copper arete cannot exceed six weeks because it causes a deficit in the hematocrit of the treated animals.
