Application of chelate compounds of trace elements and their influence on physiological status of pigs

The efficacy of Bioferron and Biocink on the physiological status of pigs is shown. The average daily body weight gain of piglets over the entire study period (4–60 days) in the control group was 0,25 kg. The greatest increase in body weight of piglets was noted in the 2nd (Bioferron 0,2 ml/kg) and 5th (Biocink 0,2 ml/kg) experimental groups, which amounted to 0,32 kg. The safety of piglets for the entire period of the experiment was 100 % in each of the study groups. The red blood cell level in the 2nd (Bioferron 0,2 mL/kg) and 3rd (Bioferron 0,3 mL/kg) experimental groups was 7,57±0,11 and 7,37±0,14 х10¹²/L, which is 7,83 and 4,99 % more than in the control (p ≤ 0,05), respectively. Among the experimental groups of piglets treated with Biocink, the highest level of red blood cells was noted in the 5th (Biocink 0,2 ml/kg) experimental group, this indicator was 7,24±0,16 х1012/l, which is 3,13% more than the control. In 90-day-old piglets, the number of red blood cells increases, its predominance in experimental groups remains. The hemoglobin level in the blood of 60-day-old piglets of experimental groups, which were given Bioferron at doses of 0,1, 0,2 and 0,3 ml/kg, exceeded the level of the control group by 14,55, 15,01 and 16,03 % (at p ≤ 0,001), respectively. In the blood of piglets that received Biocink at doses of 0,1, 0,2 and 0,3 ml/kg, the level of hemoglobin exceeded by 12,52, 12,83 (at p ≤ 0,001) and 10,38% (at p ≤ 0,01) the level of the control group, respectively. In the blood of 90-day-old piglets, the superiority of the hemoglobin level in piglets of all experimental groups over control remains. The greatest hematocrit value was observed in piglets of 60 days of age in the 2nd and 3rd experimental groups, which were given Bioferron at doses of 0,2 and 0,3 ml/kg, it was 41,29 0,29 and 41,65±0,30 %, which is 7,16 and 8,09 % more control (p ≤ 0,01). In 90-day-old piglets, a significant increase in hematocrit was observed in all test groups. A decrease in the number of leukocytes in the blood within the physiological norm indicates the normalization of metabolic processes in the body of pigs, which is expressed in the positive dynamics of changes in the morphological composition of the blood of animals treated with Bioferron and Biocink. The ratio of different forms of leukocytes in 60 and 90 daily piglets was within the physiological norm.
