Effects of phytase on growth and slaughter performance, digestibility and nitrogen and mineral balance in heavy pigs

Italian Journal of Animal Science, 2012
The study aimed at evaluating the effects of phytase (Ronozyme® NP) to the diet of fattening pigs. In comparison with a control diet (C) which included 0.5% calcium salt (CaHPO4), two diets without CaHPO4 were tested: 150Phy and 300Phy, which contained ...
