Avaliação do colostro de éguas e utilização da silagem (fermentação anaeróbica) como método substituto do colostro in natura

Abstract

Two studies were carried out to evaluate the quality and constitution of colostrum from mares and to use a substitute method of colostrum in natura when it is unavailable to the neonatal foal. The first study describes the literary data regarding the constituents of colostrum, as well as it quality. The literary data are valid for gathering and comparing with the collected data of the subsequent study. In the second study it was perfume the evaluation of the quality of colostrum in natura and in the anaerobic fermentation of colostrum. The colostrum of 35 mares was used, all the mares demonstrated healthy gestation. Colostrum was collected and evaluated within six hours of delivery. To prepare the silage, the colostrum was collected and placed in sterile bottles and sent to the microbiology laboratory of the Federal University of Pelotas. The anaerobic fermentation was elaborated in different periods and proceeded with physical-chemical, immunological and microbiological evaluation. It was evidenced that the anaerobic fermentation of the equine colostrum maintained the constituents, demonstrating that the silage can be used as an alternative method to storage the equine colostrum.
