Description

1. To determine optimal amount of phytase supplement of hens feed mixtures with different contents of total and available phosphorus. To reduce cost of inorganic phosphorus and phytase. To find out relationships between phosphorus, phytase and calcium in diets in relation to performance and safety of egg production. To determine whether microbial phytase changes environment of the digestive tract. 2. To replace synthetic kantaxanthin (EFSA count its on the potentially hazardous substances for humans) by natural sources of carotenoids. 3. To find out microbial contamination of eggs from different housing systems.
