Effect of Knotweed in Diet on Physiological Changes in Pig

Knotweeds (Reynoutria spp.) are plants producing useful secondary metabolites, including stilbenes (resveratrol and piceid have been studied more thoroughly) emodin. Many studies shown the positive effects of resveratrol on health status humans animals. Resveratrol has added into pigs’ diet as a pure extract, but it never supplemented fodder with knotweed biomass which contains other thus we would expect provide complex effect. The study objective is to discover whether 2 weight percent addition will their health. We compared two groups Prestice Black-Pied pigs, experimental group was fed by rhizomes additive, control without additive. Investigated parameters were feed consumption, composition excrements, increment, muscle-to-fat ratio, fatty acid blood haematology biochemistry. stimulated whole range physiological changes. It positively growth increased back fat proportion muscle, statistically significant only in gilts. On hand, changes seemed be unsatisfactory. first development, detailed research desirable.
