ABSTRACT: This study investigated the effects of dietary
supplementation of indigenous phytase producing live yeast cultures on growth
performance, phytate degradation and blood biochemical parameters of weanling
rabbits. Fifty-six rabbits (28 males and 28 females) were allotted randomly
into four groups containing a control and three groups administrated each with
the yeasts Saccharomyces cerevisiae ADR1B1, Hanseniaspora jakobsenii ADR3E1, Hanseniaspora guilliermondii RD31 during 8 weeks. The results
showed that the administration of the three yeast strains accelerated the weight
gain and improved rabbits growth performance in comparison to the control
group, but did not affect the serum biochemical and hematological parameters.
The highest weight gain (1715.95 ± 236 g), and phytate degradation rate (73.82%
± 0.92%) and the lowest biochemical parameters (triglycerides, cholesterol, HDL
and LDL) were observed on rabbits fed with the yeast Hanseniaspora
jakobsenii ADR3E1. This indigenous yeast species, which is used for the
first time in animal feeding provided the best beneficial effects in rabbit breeding.
Therefore, based on this finding, Hanseniaspora jakobsenii ADR3E1 can be
recommended to supplement rabbit diets for growth performance and profitability
enhancement.
