ABSTRACT


The aim of study was to determine effect of applied in calf milk replacer feed additives – mannanooligosaccharides, inulin and yeast nucleotides on rumen microflora, level of serum immunoglobulin and calf health condition. The results of research related to effect of mannanooligosaccharides, inulin and yeast nucleotides added to calf milk replacers on calf rearing and health condition point to higher final body weight as well as higher daily body weight gains, better concentrate intake and feed conversion ratio all rearing long. Feed additives, especially yeast nucleotides had beneficial influence on faeces scores – better consistency (less watery and well formed). It can testify to better calf health condition. Additives applied in calf milk replacers did not clearly affect on morphological and biochemical blood and serum parameters. Merely blood glucose increased while levels of cholesterol and plasma urea N were reduced. The higher level gamma-globulin as well as better passive immunity transfer were stated in calves receiving mannanooligosaccharides and yeast nucleotides in amount 4g/day/head in milk replacer. Applied in calf milk repalcers mannanooligosaccharides, inulin and yeast nucleotides, especially inulin in amount 6g/day/head increased calf rumen pH and decreased level of rumen ammonium nitrogen. Concentration of total volatile fatty acids in rumen, especially acetate and propionate were higher in calves receiving in milk replacer prebiotic feed additives, especially mannanooligosaccharides and yeast nucleotides what was confirmed by higher body weight gains. Moreover the total bacteria count increased while the concentration of protozoa in the rumen fluid decreased, particularly in calves receiving inulin.

Key words: mannanoligosaccharides, inulin, yeast nucleotides, calves, rumen microflora, blood, immunoglobulin, growth performance, health condition.
