- Abstract
The laying performance indicators of laying hens include laying rate and average egg weight of qualified eggs. The laying performance of laying hens is affected by many factors such as the individual laying hens, feeding management, breeding environment, disease and other factors. It is very important to study the influence of various factors on laying performance and its time delay effect for laying hen breeding. A vector auto-regressive (VAR) model was established with laying hens’ feeding, drinking water, environmental temperature and humidity as the main influencing factors to realize the medium and short-term prediction of egg production rate. The prediction accuracy rate was 98.6%. Based on this model, the analysis showed that the environmental temperature had the greatest impact on the laying rate of laying hens and the impact lasted for 3-4 days and reached the peak on the first day. The food intake had the greatest impact on the average egg weight and the impact lasted for 4-5 days, also peaking on the first day.
