Evaluation of the characteristics from rumen fluid associated with digital thermography and pedometrics activity in Holstein cows

Abstract

The productivity and the increase in the number of cattle raised in semi confinement and confinement regimes create disorder primarily affecting the gastrointestinal tract of cattle, resulting in lameness in foot of negative economic impact on dairy farming worldwide. Thus, this study aims to correlate the occurrence of subacute ruminal acidosis in animal production with high incidence of laminitis asymptomatic. This correlation will be established from the values of ruminal pH collected via oral gavage and the images of digital thermography, seeking early identification of changes in temperature produced by this inflammatory process Foot. The correlation also consider the data obtained by pedometrics where observed individual behavioral changes that will assess pain behavior measured in the number of steps of the animals. Will be used 200 Holstein cows, divided into three groups, which are established from the stage of lactation and daily production. The rumen fluid will be obtained in a single moment, through ruminal probe pray. Prior to survey the animals will undergo digital thermography of four members. Notes the number of steps, number of times the animal lies down and time position, will be taken with pedometrics. This evaluation will be considered and analyzed the measurements of pedometrics the last seven days. The data will be statistically analyzed, aiming to establish correlations. (AU)
