COMPONENTS OF EGG PRODUCTION OF EGG-LAYING CHICKENS AND THEIR ASSOCIATION WITH EGG PRODUCTION
Main Article Content
Abstract
Egg production in laying hens is a complex biological process influenced by multiple factors, including genetics, hormonal regulation, nutrition, and management conditions. However, the interaction between these components and their direct impact on total productivity remains insufficiently studied.
This study aims to identify the key physiological, biological, and management-related components affecting the egg production performance of Borkovskaya Barvistaya hens and to analyze the correlation between these parameters and overall egg yield.
The experiment was conducted over a 52-week period on hens kept in standard two-tier cage systems. Variables such as age at first egg, age at 50% production, egg weight at 30 weeks, peak production intensity, intensity index, and average weekly production growth were measured. Data were processed using correlation analysis.
The highest correlation with total egg yield was observed in the intensity index (r = 0.97). Early sexual maturity and faster ascent to peak production also positively correlated with higher productivity. The relatively low peak production value (84.8%) suggests potential for genetic enhancement.
The study highlights the strong interdependence between physiological indicators and egg productivity. The integration of egg-laying curve components into selection strategies is recommended to enhance breeding efficiency and improve long-term egg production outcomes.
