Acetic acid, vinegar, and citric acid as washing materials for cuticle removal to improve hatching performance of quail eggs.

ABSTRACT: The cuticle is the outmost layer of the eggshell and may affect the hatchability by modulating eggshell conductance. Three different solutions using acetic acid (AA), vinegar (V), and citric acid (CA) for cuticle removal by egg washing were developed, and the effects of cuticle removal on hatching performance of quail hatching eggs were evaluated. A total of 5,238 fresh quail hatching eggs were randomly divided into 9 treatments as follows: unwashed control, nondipped (CND); washed control, water dipped (CWD); standard control, 0.13% sodium hyperchlorite (CSH); 2% AA (AA2); 4% AA (AA4); 44.4% V (V2); 88.8% V (V4); 2% CA (CA2); and 4% CA (CA4). Overall, AA4, V4, and CA4 treatments significantly improved the hatchability of fertile eggs (95.42%, 94.16% and 95.66%, respectively) (P < 0.05) an
