Effects of In Ovo Injection of Coenzyme Q10 on Hatchability, Subsequent Performance, and Immunity of Broiler Chickens

Table 2

Effect of different levels of Q10 on hatchability (%), body weight, and egg weight (g) at hatching time.

Item	Hatchability (%)	Body weight (g)	Egg weight (g)	Body weight/ Egg weight
Sham control	83	40.37	60.14	67.13
Un-injected control	88.5	41.82	60.54	69.08
Q10, 0.1 mL/egg	92	42.85	60.78	70.50
Q10, 0.2 mL/egg	91.5	43.43	60.07	72.30
SEM	1.27	0.54	0.28	2.26
P-value	0.025	≤0.002	0.824	≤0.001

Means with common letters in the same columns are not significantly different (P>0.05). SEM: standard error of the means; FI: feed intake; WG: weight gain; FCR: feed conversion ratio; Q10: coenzyme Q10.
