Abstract
The development of agricultural production at the present stage requires the efficient use of resources. In addressing this issue in egg poultry is a significant factor in the increase in lifetime use of laying hens while maintaining the highest level of their productive qualities. In the organism of laying hens to the third phase of egg laying occur a number of changes that affect the intensity of oviposition, as eggs and metabolism. It has been established that the use of the spore probiotic “Basulifor” in the diet of laying hens of the “Lohmann White” cross from the beginning of the third phase of oviposition lengthens the productive cycle and allows maintaining high egg production at an older age (P0.999).
