Efficiency of the protein-prebiotic feed additive “Nutamar” in fattening rabbits

The study examined the effect of the feed additive “Nutamar” on nutrient digestibility and productivity of rabbits. Three groups (control, 3 and 5 g/kg of feed) were evaluated in a balance trial (45–77 days), growth performance (40–115 days), and slaughter parameters (120 days). The best results were obtained with the dose of 5 g/kg: digestibility of dry matter, crude protein and crude fat increased by 3.3–5.0% (p<0.01), average daily gain by 9% (p<0.001), carcass weight and dressing percentage by 11.4% and 5.1% (p<0.05). It was concluded that the dosage of 5 g/kg is preferable.
