Effect of polyclonal antibodies on the hatchability of eggs. The eggs were incubated with rat serum against recombinant protein and normal rat serum (control) at different dilutions (1:10, 1:40, 1:160, 1:640, and 1:1256) for 24 h, and the hatching rate of eggs was counted. Data are presented as mean ± SEM
