Two fattening trials were conducted to study drinking water pH and experimental infection of chickens with the species Cryptosporidium meleagridis as affected performance. Statistically insignificant differences were recorded in live weight and feed consumption when fed with alkaline water of 10.05 pH compared to feeding with drinking water and acid water of 2.5 pH value. In experimental peroral infection of 7-day old chickens with oocysts of C. meleagridis in a dose of 5.105 oocysts/chick, their growth decreased on 7th day after infection. Feed consumption was negatively affected on the following day after infection. Marked increase of feed consumption and the number of died chickens were recorded in the group fed with alkaline drinking water at simultaneous experimental contagion.
