Effect of Heat Exposure on Gene Expression of Feed Intake Regulatory Peptides in Laying Hens

Figure 2

Effect of heat stress on gene expression of neuropeptides in the hypothalamus of laying hens. (a) Neuropeptide Y (NPY) and Agouti-Related Protein (AgRP); (b) Ghrelin and cholecystokinin (CCK); (c) Proopiomelanocortin (POMC), cocaine- and amphetamine-regulated transcript (CART), and corticotropin-releasing hormone (CRH); (d) Melanocortins 1, 4, and 5 (MCR-1, MCR-4, and MCR-5). Values indicate mean ± SE ( 𝑛 = 6 ). a, bMeans with different superscripts are significantly different ( 𝑃 < 0 . 0 5 ).
