Countering the antibiotics excessive use by the exploitation of promising immunostimulants alternatives is a trending strategy in modern animal husbandry. This research assessed the impact of novel dietary symbiotic supply at different levels on growing rabbits’ performance. Forty-five New Zealand White rabbits (aged seven weeks, weighing 1075 ± 9.78 g) were randomly allotted to five groups. Rabbits were fed the basal diet as control and the other groups supplemented with synbiotic (Saccharomyces cerevisiae along with β-glucan and mannan-oligosaccharide) at an inclusion level of 0.5, 1.0, 1.5, and 2.0 g/kg diet for 6 weeks. Results indicated that synbiotic addition increased the feed intake (p=0.01), enhanced the growth performance and feed conversion ratio (linear, p≤0.001; quadratic, p≤0.002) with the 0.5 g/kg diet level being the most effective. The synbiotic supply increased the serum total protein and albumin (quadratic, p≤0.024) as well as lipase and amylase (linear, p<0.001; quadratic, p=0.001), while decreased alanine-aminotransferase, urea, triglycerides, and glucose (quadratic, p≤0.023) as well as cortisol (linear, p<0.001; quadratic, p≤0.001). The concentrations of immunoglobulin-G, immunoglobulin-M, red blood cells, hemoglobin, hematocrit, and platelet count increased (linear, p≤0.001) and white blood cells decreased (linear, p<0.001) by the synbiotic inclusion. The hot carcass weight and the percentages of dressing, and carcass cuts were increased (quadratic, p≤0.02) in which the 0.5 g/kg diet level was better. Taken together, the current dietary synbiotic supplementation of 0.5 g/kg diet could pave the way for promoting the rabbits’ growth and health status, thus, it is advisable to utilize these findings in the husbandry of rabbits under commercial production conditions.
