The aim of the paper was to compare the effect of prebiotics (inulin and/or mannan-oligosaccharides,
MOS) and bee products (bee pollen and/or propolis) on productive and reproductive performance of rabbit
does. Seventy nulliparous V-line female rabbits were distributed among 7 groups. The groups were fed the
same diet and received no supplements (control group), natural molecules (bee pollen and/or propolis) at
200 mg/kg body weight (BW) or prebiotics (inulin and/or MOS) at 35 mg/kg BW. Productive, reproductive,
biochemical and haematological traits were investigated. Bee pollen with propolis significantly increased
body weight gain of does 1 wk after mating (3.53%), decreased feed intake (4.49%) and caused larger litter
size (39.4%), heavier body weight of litter (17.7%), a greater number of kits born alive (48.7%), higher weight
of kits (87.81%) at 28 d of age, higher milk yield (43.6%) and more favourable milk conversion ratio (31.6%).
Moreover, bee pollen with propolis had significantly increased plasma total protein (43.1%), albumin (45.7%),
globulin (41.0) and progesterone (60.5%), and had a significantly decreased plasma cholesterol (31.1%),
aspartate aminotransferase/alanine aminotransferase ratio (20.3%) compared to the control group. Does
treated with growth promoters had significantly fewer services per conception (22%) and greater fertility rate
(21%) compared to the control group. Inulin with or without MOS significantly increased plasma glucose
(49.9 and 50%, respectively) and feed cost (90.2%) compared to the control group. Supplementation of MOS
or bee pollen with or without propolis had significantly greater relative economic efficiency (61.9, 55.1 and
27.1%, respectively) than the control group. MOS and bee pollen with or without propolis are able to improve
productive and reproductive performance and economic efficiency of rabbit does in comparison to the
unsupplemented group.
