The effect of thermal manipulation for 3 h and 6 h on average myofiber diameter in chicks at various days of age

Age, days	Myofiber Diameter, μM			Total Myofiber Number
Age, days	Control	3H	6H	Total Myofiber Number
9	17.88±0.62^*	19.55±0.62^*	16.28±0.01^*	2,000
13	20.07±2.20^*	24.35±0.31^†	24.35±0.31^†	4,000
25	24.29±0.83^*	31.44±2.77^†	30.62±2.28^†	4,000
35	41.45±1.29^*	46.12±2.16^†	46.54±2.01^†	2,000

Values are means ± SE of myofibers derived from 5–7 chickens per day. 3H and 6H, groups receiving thermal manipulation for 3 and 6 h daily, respectively.

Values with different symbols differ significantly within the same age (P < 0.05).
