Rendimentos de subprodutos do abate de bovinos na indústria frigorífica

Abstract

The objective of this study was to evaluate the byproducts yields along the months and year seasons from beef cattle slaughter in an abattoir of Rio Grande do Sul state. This work was a descriptor search with primary dates collect. Dates were collected in the industrial processor line of Frigorífico Silva Indústria e Comércio Ltda. abattoir situed in Santa Maria, during 2011 year. Was measured the values in e kilograms for each processed product, dividing them by the number of slaughtered head, per day. The job shows month and seasonal results of the variations in production. The work shows there is a seasonal difference in animal categories slaughtered during the seasons, as long in the production of the majority of the byproducts of bovine slaughter, what could be effect of products process variation. In general, the red offals shows increase tendency in production over the year, having their lowest production in summer, and his maximum production in spring. In these offals, the item of biggest oscillation was the lung, that gets to have the variation coefficient about 15%. During the autumn occurs the bigger production of industrial meat and hide. There was a major production of white offals in winter station, as well the no-edible byproducts. From items that shows statistic difference, the biggest variation was sliced frozen stomach, which reached a variation coefficient of 91,9%, with their minimum production average in 0,40 on summer and 1,10 on winter, period that has a bigger production due to demand for typical dishes in the South region. This work has a great data volume, and serving to generate comparative results and instigate researches that studies the production and the yealds of these important byproducts not only for the abattoirs, but to all the meat chain.
