TL;DR: Data suggest that the mammary gland strives to maintain cell-to-cell junction integrity by synthesizing more proteins to compensate for protein losses induced by heat stress, and results in increased gene expression without altering protein expression of mammary epithelial cell junction proteins, and does not substantially influence the integrity of mammaries.

TL;DR: Evaluating the effects of maternal HS during the dry period on dry matter intake, growth, and metabolism in heifers found it reduces calf starter intake and growth, alters blood metabolite profile, and increases noninsulin-dependent glucose uptake.

TL;DR: Removing active cooling impairs lactation performance and affects gene expression of proteins involved in the mammary epithelial barrier, and feeding a portion of dietary zinc as ZMC improves the integrity of the Mammary epithelium.

TL;DR: In conclusion, feeding a betaine-containing liquid supplement from far-off through early lactation improves lactation performance but increases adipose tissue mobilization and production of ketone bodies inEarly lactation.

TL;DR: The results suggest that maternal heat stress desensitizes a calf's stress response and alters the fetal development by reducing the secretion of insulin-like growth factor-I, prolactin, and insulin.
