Table 1 Reproduction parameters achieved with enrofloxacin- and marbofloxacin-treated eggs. Reproduction parameters measured include: Egg numbers set = total eggs of the group incubated, Fertility = percentage of fertilised eggs, Hatchability = percentage of chicks hatching from the fertilised eggs, Pre-term hatching = percentage of chicks hatching on days 19 and 20, Hatching chicks with joint deformity = percentage of chicks showing signs of swollen joints, Total hatching success = percentage of chicks hatching from total eggs set into the incubator. Groups: C1 = untreated control, C2 = sham-treated control eggs (aqua pro injectione); E1, E2, E3 = groups exposed to 1, 10 and 100 μg of enrofloxacin per 1 g of egg weight, respectively; M1, M2, M3 = groups exposed to 1, 10 and 100 μg of marbofloxacin per 1 g of egg weight, respectively; * = p < 0.05, ** = p < 0.01 (compared against control group C1 or C2)
