Effect of physical activity of laying hens on egg quality

Summary

The experiment was performed to study the combination of effects of diets and physical body activity (training) on laying hens’ performance, egg weight, yolk proportion and fatty acids profiles. Results of present experiment showthat dietary fat source affects egg production rate, egg weightand yolk proportion. In diets palm oil, soybean oil and linseed oil were used as fatty acids sources. Physical activity was provoked on a treadmill.

Exercise on the treadmill reduced feed intake and egg production. No significant effect of dietary fat source and running treatment was observed on laying hens performance. Diets significantly influenced egg weight, yolk proportion and fatty acids profiles either egg weight, yolk proportion or fatty acids profiles indicating a dominating effect of dietary fat source.
