This study evaluated the colostrum and colostrum silage of two dairy breeds cows and the quality during storage. We used 5 samples Gir cows and 5 of the Jersey breed harvested in the first milking and evaluated at 0 and 15 days of storage. Were determined in the samples pH, temperature, acidity in lactic acid, acidity, lactose, glucose, total fat, total nitrogen (TN), non-protein nitrogen (NPN), casein, molds, yeasts and enterobacteria. Statistical analysis of these variables was used analysis of variance (ANOVA) at 5% significance level. There were significant differences between the races in pH parameters at day 0, crude fat on day 0, total nitrogen and crude protein on days 0 and 15 and casein on days 0 and 15. In the other parameters no significant differences were observed between the races . Therefore, the results obtained indicate that there were significant nutritional difference between silage colostrum races Girolando and Jersey.
