Experimental analysis shows improved hatchability and reduced embryo mortality in breeder broiler eggs with quaternary ammonium treatment, indicating its potential as an effective sanitizer.
This study examined the effectiveness of quaternary ammonium compound (QAC) as a sanitizer for controlling microbial activity on fertile eggshells and its impact on hatchability. A total of 660 fertile eggs from 60-week-old Lohmann White breeder hens were treated with QAC at concentrations of 1/100, 1/200, and 1/300 ml/L or left unsensitized. Results showed that QAC significantly reduced total aerobic bacteria on eggshells before incubation and at day 18, compared to non-sanitized eggs. Hatchability was higher, and embryo mortality was lower in eggs treated with QAC, particularly at the 1/300 ml/L concentration, compared to the non-sanitized group. Egg weight decreased across all treatments during incubation, with the highest weight loss observed at the 1/100 ml/L concentration. Overall, QAC demonstrated efficacy in reducing microbial contamination and enhancing hatchability, though its effects on egg weight loss varied.
