INFLUENCE OF FEED ADDITIVE "ENZAKTIVE MIX" ON THE HEMATOLOGICAL PROFILE OF THE BLOOD OF SOWS AND THEIR PIGLETS

Abstract

The dynamics of the haematological profile changes and the productivity of sows and piglets obtained from them when feeding the feed additive "EnzActive Mix" were described in the article. The feed additive contains yeast of the genus Saccharomyces cerevisiae with an activity of at least 1.5 x 10^10 CFU/g and a six enzymes complex with protease, cellulase, xylanase, ɑ-amylase, β-gluconase, phytase, which are located under the layer of yeast cells. The results of the study showed that the use of "EnzActive Mix" in sows and their piglets’ diet has a stimulating effect on the oxygen transport function of blood. This is evidenced by a higher number of erythrocytes and platelets, a higher concentration of haemoglobin and haematocrit in the blood of sows of the experimental group compared to the control group on 21st day of lactation (p<0.05). Addition of the feed additive "EnzActive Mix" to the diet caused changes in certain forms of leukocytes ratio in the sows’ blood. Thus, during this period, a higher (p<0.05) relative lymphocytes number and a tendency to decrease of segmented neutrophils number in the blood of experimental group sows compared to the control group were found. Similar changes were noted in the haematological parameters study of piglets obtained from these sows. In particular, the leukocytes number in the blood of the experimental group piglets at 5-, 14- and 28-day age was higher than in their peers of the control group. At the same time, on the 5th day of life, the differences relatively to the control group animals were significant (p<0.05). Feeding of the feed additive led to a decrease in the segmented neutrophils relative number in the blood of the experimental group piglets on the 14th and 28th day of life (p<0.05) and an increase in the lymphocytes number (p<0.05) during the indicated periods of the study. The positive effect of the feed additive "EnzActive Mix" on the productivity parameters of the studied animals was established. In particular, the body weight of experimental group piglets at 5-, 14- and 28-day age was 7.8%, 13.7% (p<0.05) and 8.4% (p<0.01) higher, respectively, than that of the control group.
