Digestibility of Dry Matter and Nitrogen and the Nitrogen Balance of Three Skimmilk Diets Fed to Holstein Calves

Eighteen Itolstein bull calves were used to determine the apparent digestibility of dry matter, nitrogen, and nitrogen retention of low-temperature-treated skimmilk (71.1C for 16 to 20 sec), high-temperature-treated skimmilk (85 to 87.7C for 20 to 30 rain), and fresh skimmilk as the sole diet during 4to ]3 and 14 to 23 days of age. The respective diets contained 77, 44, and 102 mg whey-protein per 100 g of milk.
