Abstract
Fresh fertile eggs were injected with four levels of selenium (as sodium selenite) into the air cell and examined after various times of incubation. The treatment effects on embryo morphology, stage of embryo mortality and body weight are reported. The correlation between wet weight vs. dry weight and protein nitrogen was 0.99 and 0.94, respectively, for the 2- to 5-day incubation period. The coefficient of correlation for wet weight vs. dry weight from 6 to 18 days of incubation was also very high (r = 0.97). The four selenium (Se) treatment levels (0.15, 0.30, 0.45, and 0.60 ppm of added Se per embryo) resulted in a significant depression of embryo wet weights at 3 and 4 days of incubation but not at 2 days. There was no treatment effect on male and female embryo wet weights from 6 to 18 days of incubation. Furthermore, there was no significant differences between male and female wet weights during this latter period. The embryo mortality resulting from the above Se treatments was 16.2, 15.1, 28.2 and 29.0%, respectively (control mortality was 8.2%), and 99% of these embryos did not develop beyond the 6-day stage. No morphological abnormalities were observed from the Se treatments.
