title: [Effect of milk substitutes with various soy bean products on the N metabolism in calves].
abstract: N-balance trials on young calves aged 3, 5, 7, 9 and 11 weeks, respectively, revealed that a mixture of soybean and whey powder accounting for 39.5% of the total protein amount can be fed without any disadvantage. Feeding this mixture gave N-balance results differing only slightly in the groups aged 7, 9 and 11 weeks. The milk replacer with a higher proportion of soybean and whey powder revealed a more unfavourable N-balance. This allows to conclude that milk replacers containing soybean preparations can be successfully applied to young calves from 5 weeks on, no disadvantages being likely as to N-balance and live weight gain.
