The Effect of Some Mineral and Phytogenic Additives, Rich in Polyphenols, on Lipid Peroxidation Process

Abstract:

Phenolic compounds show promising and powerful antioxidant properties that can protect both humans and animals against lipid peroxidation. The introduction of plant polyphenols, as plant powders or polyphenolic extracts, in animal diet can solve two major problems: the decrease of oxidative stress in animals and the improvement of nutritive quality of meat and meat products obtained from these animals. In this study it was analyzed the lipid peroxidation process in the liver sampled from weaned pigs, fed with rations in which the addition of Fe, Cu, Mn and Zn derived from inorganic compounds and phytogenic additives (oregano - Origanum vulgare and bilberry fruits - Vaccinium myrtillus). The obtained results show that the highest rate of lipid peroxidation was recorded in case of the samples collected from the animals that received mineral additives in ration (Fe-169,41 ppm, Cu-9,44 ppm, Mn-33,98 ppm, Zn-96,7 ppm) and the introduction of phytogenic additives led to the decrease of lipid peroxidation processes. Due to their antioxidant action, the introduction of oregano and bilberry powders in the ration of pigs determined the decrease of lipid peroxidation process in the liver in the conditions of total or partial replacement of Fe, Cu, Mn and Zn inorganic compounds. Keywords: phytogenic additives, antioxidant activity, malondialdehyde, oregano, bilberry
