The trophic dependence of lipid peroxidation and antioxidant oxidoreductases in blood plasma of the European rabbit (Oryctolagus cuniculus) on the weeds consumed by it

Studying trophic connections between animals and some weeds is important to understand the processes taking place in some populations during different successions. The results can be used for the development of new, ecologically clean feed for production animals. The aim of the investigation was to study the trophic dependence of the lipid peroxidation (LPO), the activity of superoxide dismutase (SOD) and catalase in rabbits’ blood plasma on their consumption of some weeds. 50 % of a rough feed was replaced with the field bindweed (Convolvulus arvensis), the common reed (Phragmites australis) and the corn thistle (Cirsium arvense). As for the rest, the ration was the same. The blood plasma of rabbits was analyzed. The spectrophotometric level of LPO, SOD activity and catalase were determined. The ability of Convōlvulus arvēnsis to influence the balance of antioxidant protection and to reduce oxidative stress was revealed.
