The possibility of improving the nutritive value of fermented colostrum for neonatal calves was investigated in 5 trials involving 164 Holstein calves and in 2 laboratory experiments. / The inoculation of colostrum with S. lactis culture ensured a highly palatable and more uniform product. Calves fed the inoculated product gained in weight quicker and consumed more starter than those fed naturally fermented colostrum. / The addition of sorbic acid to S. lactis inoculated colostrum controlled the mold contamination, particularly during hot summer weather. This lowered the degradation of lactose and protein and extended the storage life. The application of 1,000 ppm of sorbic acid during the first 4 days of storage is, therefore, recommended. / An undesirably narrow ratio of Digestible Energy/Digestible Protein in colostrum was widened through the use of a supplementary energy source. These treatments also improved the performance of calves.
