Popis: Milk or commercial milk replacer blends are the most expensive components in final costs of calves breeding. Colostrum is available and it is the appropriate sources for calves' nutrition, being an excellent option as milk substitute. Besides having both nutritional and immunological characteristics that are superior to milk, colostrum represents no costs to the producer. However, difficulties in preservation of colostrum generate controversy results. The aim of this study was to evaluate the anaerobically fermented colostrum (colostrum silage) as liquid diet for dairy calves. We evaluated the microbiological and physicochemical properties of silage, and performance of 31 animals up to 60 days age. From 21 days until 360 days of fermentation we isolated only bacteria of the genus Lactobacillus spp. The physicochemical evaluation of colostrum silage revealed a tendency to maintain the protein, dry matter and fat values during the evaluation period. The average weight gain of calves fed with milk was 0.6kg day-1 for female and 0.6g day-1 for males while those fed with colostrum silage was significantly higher (P
