Abstract

This study aimed to determine the relationship between hatchability traits, moisture loss and mortality in commercial Lohmann Brown Lite breeders in South Africa. A total of 5400 hatchable eggs were incubated. Descriptive analysis and the Pearson correlation coefficient were computed using MiniTab17. Fertility, embryo livability and mortality, total moisture loss, and hatchability were 95.06%, 86.56%, 6.37%, 13.27%, and 93.63%, respectively. There is a positive correlation between egg fertility and embryo livability (p<0.001; r=0.86) and between egg fertility and hatch of all set (r=0.82). There is a positive correlation between embryo livability and hatch of all sets (p < 0.001; r = 0.81). A negative correlation exists between moisture loss during days 0-10 and 11-18 of incubation (p < 0.001; r = -0.64). A positive correlation between total moisture loss and that during days 0-10 (p<0.01; r=0.44) and 11-18 (p<0.05; r=0.41) exists. A negative correlation was observed between hatch of fertile eggs and moisture loss (p < 0.05; r = 0.32). First-grade yield shows a positive correlation with total pullet yield (p < 0.001; r = 0.95). First-grade pullet yield has a negative correlation with male yield (p < 0.001; r = -0.95). Second-grade pullet yield has a positive correlation with overall pullet yield (p<0.05; r=0.36). Second-grade pullet yield has a negative correlation with male yield (p<0.05; r=-0.36. These results indicate that hatchability, embryonic mortality, and moisture loss are strongly influenced by fertility and incubation conditions. Optimizing these factors through proper management can improve chick quality, enhance hatchery efficiency, and increase productivity and profitability, contributing to sustainable poultry production and national food security.

Abstract

Globally, chicken production continues to grow, and the consumption of chicken products is surpassing that of other animal products. Embryo mortality, poor hatchability, and chick quality remain the biggest challenges in both natural and artificial incubation. This review investigates the multifaceted effects of flock age and maternal nutrition on key reproductive parameters in broiler chickens, including hatchability, embryonic development, and chick quality. Aging flocks negatively impact reproductive performance and subsequent chick quality; proper management and optimizing storage parameters can mitigate these effects. The age of the flock and maternal nutrition collectively influence hatchability, which in turn determines the potential for successful embryo development and ultimately, the quality of the day-old chick, highlighting the interconnectedness of breeder management and progeny performance. Synthesizing complex biological and nutritional interactions is crucial for understanding the key elements that contribute to optimal poultry production outcomes. By optimizing maternal nutrition, the industry can expect improvements in hatchability, reduced early chick mortality, and enhanced overall chick quality, resulting in significant economic benefits. Furthermore, this review would inform and refine industry practices in broiler breeder management. Poultry researchers and producers can synthesize this information to formulate more effective and economically viable feeding programs for breeder flocks.
