In addition to considerations of drug effectiveness, cost and the use of alternative means, the egg producer must evaluate possible detrimental effects on production rate, residuals, and egg quality characteristics. The hatcheryman is further concerned with effects on fertility and hatchability of fertile eggs. Sulfaquinoxaline continuously fed at the 0.033% level was reported by Smith et al. (1952) to result in small but non-significant decreases in production, fertility and hatchability. Neither furazolidone nor nitrofurazone affected egg production, fertility or hatchability in a study by Francis and Shaffner (1956). Stiles (1962) found that furazolidone had no significant effect on fertility … |
