Productivity and hematological parameters of blood of young pigs at fatten-ing for feeding protein vitamin mineral supplement

Abstract

The article presents data on the productivity and hematological parameters of the blood of young pigs for fattening for the inclusion in their diet of a new protein vitamin-mineral supplement with essential oils, Efiprot. Plant essential oils are natural phytobiotics containing fat-soluble vitamins, polyunsaturated fatty acids, volatile acids, aldehydes, and other biologically active substances with bactericidal and antiseptic properties, increased appetite, and secretion of digestive juices. Thus, they provide better feed conversion and increased productivity. Protein vitamin-mineral supplement Efiprot is for a diet consisting of barley grains (50 %) and wheat grains (35 %). The experiment was carried out on two groups (12 heads in a group) of young pigs, a cross of Large White and Landrace. At the beginning of the experiment live weight of the animals was 35 kg; at the end, it was 110 kg. Control group animals were fed a supplement without essential oils; experimental group animals were additionally fed a dose of essential oils (200 g per 1 ton of supplement). Feeding supplements with essential oils positively affected pig productivity and feed growth. The absolute increase in live animals of the experimental group averaged 68.6 kg, average daily was 762 g; the corresponding values of the control group were 63.8 kg and 709 g for 90 days. Feeding protein vitamin-mineral supplement (PVMS) increased average daily gain by 53 g or 7.48 %, while feed consumption per 1 kg of live weight gain was lower by 0.3 energy feed units or 6.69 % than the control one. Hematological parameters of pig blood fed by PVMS Efiprot corresponded to the limits of the physiological norm. At the end of the experiment, an increase in erythrocytes, total protein, and hemoglobin was observed in the blood of the experimental animals, which is consistent with an increase in meat productivity. A slight increase in the mass of basophils, eosinophils, and leukocytes is adaptive and incredible.
