Opportunities to improve health and production performances of trout fed Salt cedar (Tamarix ramosissima) and Dog rose (Rosa canina) phytoadditive supplements

Considering the benefits of phytoadditives in livestock production, they are increasingly being used, opening new favorable perspectives in efficiency of farm growth species. Given the diversity and relatively safe effects of the impact (side effects) that it had phytoadditives on production increase, improving products quality and increasing resistance to disease or to reduce losses, their usage seems to be a growing and a suitable for several species, including those from aquaculture. Given this situation, this paper presents the results obtained from research that focused on analyzing the impact of two phytoadditives, Salt cedar (Tamarix ramosissima) and Dog rose (Rosa canina) respectively, on growth performance and stock losses (mortality). Studies was conducted on a stock consisting of 800 Brook trout (Salvelinus fontinalis) individuals, during six months (185 days).
