Food intake dependent and independent effects of heat stress on lactation and mammary gland development

Abstract

Statements 13This study demonstrates that heat stress decreases lactation and mammary development through food 14 intake dependent and independent mechanisms. 15 16 ABSTRACT 17With a growing population, a reliable food supply is increasingly important. Heat stress reduces 18 livestock meat and milk production. Genetic selection of high producing animals increases endogenous 19 heat production, while climate change increases exogenous heat exposure. Both sources of heat 20 exacerbate the risk of heat-induced depression of production. Rodents are valuable models to 21 understand mechanisms conserved across species. Heat exposure suppresses feed intake across 22 36 37
