Meat of rabbits is considered to be a valuable dietary product. It is a source of complete protein, minerals and vitamins. It is second only to meat of turkey by the content of nitrogenous substances. It is known the blood composition is a symptomatic reflection of the intensity of metabolic processes that take place in the animal’s body under the influence of certain feeding factors. Testing of new feed additives in animal diets should be accompanied by in–depth blood analysis. Thus, the purpose of this research is to investigate, along with the performance, the effect of feeding different doses of Prebiolact–Cr on the morphological and biochemical blood values of fattening young rabbits. The research was conducted in four groups of young rabbits selected by the principle of analogues. The basic period of the experiment lasted for 42 days; it was divided into six sub–periods lasting for seven days. Animals of the second group, together with complete granulated mixed feed, received Prebiolact–Cr in the amount of 1.5 g, the third – 2.0 g and fourth – 2.5 g per rabbit daily. During this scientific experiment, young rabbits were kept in two–high cage batteries with five animals in each rabbit hutch, females and males were kept separately. Morphological and biochemical blood values were within their physiological norm when prebiotic preparation Prebiolact–Cr was introduced into the diet of young rabbits at the doses of 1.5, 2.0 and 2.5 g per rabbit daily. Prebiolact–Cr dose of 2.0 and 2.5 g per rabbit daily leads to haemoglobin increase by 4.63% in the third group and 9.5% in the fourth group. Studied feed additive at the dose of 1.5 g per head daily causes the increase of segmented neutrophils by 6.1%, reduction of monocytes by 0.9%, compared to the control group. Glucose content in the blood of experimental rabbits increased by 5.9%, 10.3% and 7.4% when the dose of the preparation became higher. Prebiotic preparation facilitates the increase of iron, potassium, calcium, magnesium and phosphorus content in blood and maintains the immune system of rabbits.
