Adicionar Tag | Resumo: | The purpose of this investigation was to determine the prevalence of subclinical mastitis, the associated factors and its treatment with the use of Drago blood at the level of the Hoya de Loja. A non-probabilistic sample was applied in 16 livestock milk production in which there were evaluated 100% of milking cows. A prevalence of 47.52% of subclinical mastitis (CMT) was found. The statistical analysis was performed with software R (3.5.2); Using Chi-square and it was found 12 variables associated with the presence of subclinical mastitis (P≤ 0.05), these were included in a logistic regression analysis to measure the risk. It was determined that the infrastructure of the regular-type farms increases the risk in relation to the ones that are in excellent conditions (OR = 5.93); the risk increases significantly with animals between eight and ten years old compared to those of two and four years old (OR = 6.34) when there are wounds in the nipples the risk is bigger than when there aren´t (OR=19,59). To prove the effectiveness of Drago blood against subclinical mastitis, it was used an experimental randomized block design with two concentrations (3% and 5%) in 32 animals; Significant differences were found between treatments, the best results were obtained in the treatments at the 5% of concentration. It was concluded that in La Hoya de Loja there is a high prevalence of subclinical mastitis in livestock, being possible to apply a prevention plan in which the identified risk factors are included, as well as alternative therapeutic measures to conventional ones such as blood treatment of 5% Drago blood that had a significant effect in the reduction of the somatic cell count. Key words: CMT, subclinical mastitis, prevalence, risk factor, Drago blood. |
