Table 7.

Effect of tempol and straw size on fertility and hatchability rates of rooster semen after freeze-thawing.

Treatments	Parameters
Treatments	Fertilized eggs	Hatched eggs	Hatched eggs ratio (hatched/fertilized, %)
0 µM of tempol and 0.25 straw size	80 (40)^b	52 (26)^b	65^b
10 µM of tempol and 0.25 straw size	121 (60.5)^a	88 (44)^a	72.7^a
0 µM of tempol and 0.5 straw size	85 (42.5)^b	56 (28)^b	65.8^b
10 µM of tempol and 0.25 straw size	128 (64)^a	95 (47.5)^a	74.2^a

Each experimental group contained 200 eggs initially. Numbers are absolute counts of eggs, with percentages (ratio respect to the initial egg count) between parentheses, except for the hatched eggs ratio.

Different superscripts letters within row are significantly different (P < 0.05).
