Effect of Saccharomyces cerevisiae dietary supplementation on productive parameters and nutrient utilization of growing Japanese quail (Coturnix coturnix japonica)
Abstract
The aim of the study was to evaluate the effect of dietary supplementation of live yeast Saccharomyces cerevisiae (LSC) at levels of 0.15 to 0.45% (dry matter basis), on productive efficiency and nutrient utilization in growing Japanese quails. A total of 155 Japanese quails aged 15 days were assigned to 4 treatments: T1 or control diet with 0% LSC, and T2, T3 and T4, with 0.15, 0.30 and 0.45% LSC (dry matter base) (Saccharomyces cerevisiae with 1.4 x 109 CFU/mL). Each treatment had n=4 repetitions (cages), with 7 - 8 birds per cage. The productive variables body weight (g), daily weight gain (ADP, g/day), feed consumption (g/bird/day), feed efficiency, and viability (%) were determined. Results were analyzed with ANOVA. The inclusion of 0.45% LSC in the diet increased (P < 0.05) feed intake, improved bird survival, and the protein utilization rate, with no effect (P > 0.05) on weight, feed conversion, and ADP in growing quails.
