Abstract :A study was carried out to determine the effects of yeast based insert ignore into journalissuearticles values(BiosaccTM); and mixture of bacteria-mold-yeast based insert ignore into journalissuearticles values(ProtexinTM); dietary probiotics on live weight, feed consumption, feed efficiency, egg production, egg weight, egg shell weight, and some blood parameters of quails raised under constant heat stress conditions. One hundred and ninety-eight 9-week-old Japanese quails insert ignore into journalissuearticles values(Coturnix coturnix Japonica); were used in the experiment. They were randomly assigned in equal numbers to three treatments: a control and two dietary probiotic treatments. Dietary treatments had six replicates with 11 quails in each. Three dietary treatments were formed by the inclusion of either no insert ignore into journalissuearticles values(control); or 0.5% of two different probiotics in the basal diet. The quails were housed in a room maintained at constant insert ignore into journalissuearticles values(32 ± 2 ºC); ambient temperature throughout the 9-week experiment. No dietary probiotic effect on quail performance insert ignore into journalissuearticles values(live weight, feed consumption and efficiency);, or egg insert ignore into journalissuearticles values(egg production, weight, and shell weight);, or serum insert ignore into journalissuearticles values(serum albumin, cholesterol, Mg, Cl, and Na); parameters was detected with the exception of serum total protein insert ignore into journalissuearticles values(P < 0.05);. In conclusion, the data suggest that dietary probiotic supplementation has no beneficial effects on the performance of laying quails under constant heat stress.
