Choosing the right proteins in calf starter feed is essential for optimizing rumen fermentation and developing healthy digestive function. Until weaning, liquid milk feed provides most of the protein supply in calf weaning plans in the first half of the initial growth phase. These proteins are essentially of dairy origin. During the second half of the initial growth phase, the dry starter feed must provide most of the protein.
Research shared in the article here discusses the impact of conventional soybean meal in calves’ starter feeds from an early age and compares it to a purified protein source. At approximately two months of age the rumen responds to a change in the nature of the proteins provided by better biomass production with a higher use of non-protein nitrogen.
