Effect of coriander and fennel essential oils on morphological and biochemical parameters of blood in pigs in the post-weaning period

Safe and organic production of livestock products is a key task of the domestic agro-industrial complex. Search and approbation of phytobiotic feed additives for ration enrichment will allow to realise the genetic potential of productivity of modern pig breeds. Special attention is paid to secondary metabolites of plants - essential oils, which have similar properties to antibiotics, but with less negative impact on the body. The aim of the work was to determine the effect of coriander and fennel essential oils on morphological and biochemical status of weanling piglets. Two experimental groups were additionally administered coriander and fennel essential oils in the amount of 0.5 ml per head per day for 30 days. The use of phytobiotics showed no negative effects and had a positive effect on metabolic processes, which was confirmed by the results of analyses. The increase of total protein in the experimental groups by 8,61-8,69%, increase of glucose level by 99,3% and 123,8% within the reference range, increase of alkaline phosphatase activity with intensification of mineral metabolism were revealed. Significant effect of fennel essential oil on the increase of iron concentration in blood will prevent iron deficiency anaemia of newborn piglets.
