The effects of early life thermoneutral (ELTN), early life heat stress (ELHS), and early life cold stress (ELCS) conditions on circulating heat shock protein 70 (HSP70) by day. Pre-transport (d−1), immediately post-transport (PT), 24 h post-transport (d1), 4 d post-transport (d4), and 7 d post-transport (d7). Error bars indicate ±1 SE. a,bLetters indicate overall day differences (P ≤ 0.01), and an asterisk (*) on the legend indicates overall early life thermal stress treatment differences (P ≤ 0.05).
