The objective of this study was to evaluate the effects of additional colostrum with different IGF-I and IgG concentrations, at 12 hours of life, on morphological characteristics of enterocytes, as well as the relationship of total amount of IGF-I ingested on the microvillus height of the calves small intestine in the first 72 hours after birth. It was utilized prolonged supply of colostrum with different concentrations, including colostrum enriched with lyophilized colostrum. Eighty two Holstein calves received, at birth, colostrum […]
