The article presents data about the physiological state and performance of the piglets organism before weaning and highlights the results of functional adaptation of animals to the action of stress in different stress periods — on seven, twenty and sixty days after weaning. It is found that after one and seven days after weaning, corresponding to stage of anxiety and resistance (by Selye) in the blood of animals of K group, the absolute number of red blood cells, white blood cells and hemoglobin concentration are decreased. After twenty and sixty days after weaning, corresponding to the stage of resistance in pigs of K group these are stabilized and body weight at the end of the experiment is increased to 14,05 kg.
It was studied the possibility of use of biological feed additives based on beta-glucan (“B-glucan”) and on low molecular weight peptides cell wall of lakto- and bifidobacteria (“Biovir”) in a diet of pigs from 5 to 45-day old to reduce the negative impact of weaning stress during adaptation to new animal welfare. These animals were characterised by significant increase of the absolute number of red blood cells, platelets, hemoglobin concentration, absolute number of white blood cells in the blood. It was shown that feeding up the pigs with the biological active additives “B-glucan” and “Biovir” in the amount of 10 mg/kg of body weight per day has the positive effect on body weight gain at the end of the experiment: after sixty days after weaning these parameters are 29,82 and 31,65 kg.
