Effect of in utero heat stress on neonatal small intestinal cell turnover, and markers associated with barrier function and immunoglobulin G transport in newborn dairy heifers.
Late gestation heat stress in dairy cows reduces offspring's capacity to absorb colostrum immunoglobulin G (IgG). This study evaluated small intestine histomorphology, cellular turnover, and gene expression profiles of in utero heat stressed versus in utero cooled heifers at birth. For the last 54 ± 5 d of gestation, p...
