PHYSIOLOGICAL STATE AND PRODUCTIVITY OF CALVES FED GOAT MILK CONTAINING RECOMBINANT HUMAN LACTOFERR
The use of recombinant proteins in diets has a positive effect on animal health, promotes intestine recovery and the creation of beneficial microbiota in the gastroin-testinal tract. The article contains the results of research in which the effect of frozen-thawed milk of goats producing recombinant lactoferrin on hematological parameters and productivity of calves at the age of 1-30 days was studied. Morpho-biochemical blood parameters were found to be within the physiological norms. The use of goat milk containing recombinant human lactoferrin in the diets of calves in the amount of 0.44-0.66 kg/head per day allows to increase the average daily live weight gain by 10,1-11,0% and reduce feed costs by 7.5- 7.7%.
