Effects of organic selenium yeast administration on perinatal performance, growth efficiency and health status in pigs

Abstract

Selenium is a vital necessary element, and its insufficiency observed in the soil and feed in a number of countries of Eastern Europe, adversely affects the health status and productivity of animals. The aim of the research was to study the possibility of using Selenium Yeast for correction of productivity of pig’s producing capacity, haematological, biochemical and antioxidant parameters of pigs in different periods of growth and development. Experiment was carried out to establish the influence of organic selenium on 75 healthy sows in farrow, milking sows and piglets before slaughtering. SELENIUM YEAST (CENZONE TECH INC, USA) contains a selenium‐methionine was mixed into the concentrates in ratio of 250 g/t, given by all the animals during feeding. Preparation from the yeast basis included 0.1% of active matter. The obtained results showed SELENIUM YEAST preparation can increase the birthrate of piglets up to 6 %, the litter weight – up to 11.1 % (P<0.05), milking capacity – up to 16 % (P<0.001) of sows in farrow and milking sows. Preparation has a positive influence on the growth and piglets preserving. The preparation showed the most remarkable influence upon the indices of the functioning of the liver. Both sows and piglets showed trustworthy 35 and 43% decreased bilirubin level and ALT activity of 18 and 77% respectively after the application of SELENIUM YEAST. Under the influence of preparation a trustworthy decrease of lipid peroxidation processes in the blood of animals occurred. Improves culinary and chemical characteristics of pork and gives a possibility to get more valuable food products enriched with selenium. The level of selenium in the muscle of animals increases up to 27.8 % (P<0.001).
