Influence of Mannanoligosaccharides Additive to Sows Diets on Blood Parameters of Sows and Their Piglets

The aim of study was to investigate the effect of yeast cell walls (mannanoligosaccharides – MOS) supplemented to a sow’s diet on some blood parameters of sows and their piglets. The investigations were carried out in two experiments with two groups of 30 sows each. The sows of groups 1 and 3 (control) received the basal diet, groups 2 and 4 (MOS) – the same diets, supplemented with yeast cell walls preparation. The sow basal diet in experiment I contained 40% of wheat and in experiment II 40% of triticale. The level of MOS supplementation (8 g per sow daily) was based on the manufacturer’s recommendations. A total of 782 piglets were received. The piglets were weighed at birth and on days 14 and 28 of age. The health status of the piglets, their mortality rate from birth until weaning, and diarrhoea incidences were recorded daily. Blood plasma contents of total protein, uric acid, urea, selected mineral elements (Fe, Cu, Zn), total cholesterol, triacyloglycerol, HDL cholesterol, and LDL cholesterol, blood plasma activities of catalase (CAT), superoxide dismutase (SOD), aminotransferase alanine, aminotransferase aspartate, dehydrogenase lactate, phosphatase alkaline, and the level of ferric reducing ability of plasma (FRAP) were determined. The addition of MOS to sows’ diet increased the values of FRAP and contents of Fe and Cu in sows, and increased the activity of SOD and CAT, level of FRAP, and contents of urea and Fe and decreased the concentration of cholesterol and LDL-cholesterol in piglets. The receiving MOS supplement. The obtained results showed that the used indicators of the antioxidant system especially SOD, CAT, and FRAP, are very sensitive exponents of antioxidant status of swine. Species of grain (wheat or triticale) did not have any significant influence on the analysed sows’ and piglets’ blood parameters.
