Causas de condenações em ovinos abatidos nas mesorregiões sudoeste e sudeste riograndense e estimativa de perdas econômicas

Abstract

The State of Rio Grande do Sul has sheep farming as one of its main livestock activities. The breeding of these animals is concentrated in the southwest and southeast mesoregions, and is explored extensively and in consortium with other activities, such as cattle farming. In view of the importance of sheep farming in the State and the lack of information related to the slaughter of sheep, this study aimed to survey the main causes of condemnation of slaughtered sheep, as well as to estimate the direct financial losses caused by the condemnations. For the study, a survey of the causes of condemnation of organs and carcasses of sheep that were slaughtered during the period from January 2017 to June 2020 was carried out. The slaughterhouse under study, operates under the Serviço de Inspeção Estadual (State Inspection Service) and mainly covers the southeast and southwest mesoregions of Rio Grande do Sul. To obtain the data, the daily records of the activities of ante and post-mortem inspection of these animals were consulted. During the period evaluated, 10,974 sheep were slaughtered, 73.40% being males and 26.59% females. Of the total number of slaughtered animals, 6,567 organs were condemned. The main causes of organ condemnation were due to hydatidosis (32.81%), organ congestion (12.99%), blood aspiration (4.79%), ruminal content aspiration (4.12%) and cysticercosis, by Cysticercus ovis (1.36%). Three carcasses were condemned for generalized cysticercosis (c. Ovis) and one for pneumonia with reflexes in the carcass. The estimated loss from the convictions in the period studied was R$ 23,642.41. When extrapolating the data obtained, for a state scenario, the annual loss can exceed R$ 360,000.00 directly to the gaúcho sheep farmer, values that are still underestimated, considering that only the data from registered establishments were considered.
