Effects of Organic Selenium Mix on the Performance, Carcass Characteristics, Tissue Selenium Distribution, and Economic Value in Finishing Hanwoo Steers

The aim of this study was to evaluate the effect of organic Se from Se-enriched alga (Chlorella spp.) and Se from Se-enriched yeast on concentrations of Se in serum and tissues, and serum GSH-Px activities and carcass characteristics in finishing pigs. The pigs were on experimental diets for a period of 3 months before slaughter with different Se supplements at the concentration of 0.3 mg Se per kg of feed. In group I (n = 12) the feed was supplemented with inorganic sodium selenite; in group II (n = 12) with organic Se from Se-enriched yeast; in group III (n = 12) with organic Se from Se-enriched alga, Chlorella spp. and pigs in group IV (n = 11) received a non-supplemented basal diet. The organic Se sources did not differ in serum Se and serum GSH-Px activities. Significantly higher Se concentrations in muscle (P < 0.01) and in the heart (P < 0.01) were found when Se from Se-enriched yeast was given, compared to the group of pigs that received Se from Se-enriched alga Chlorella spp. The Se content in livers and ovaries did not differ between the two organic Se sources. The use of both organic Se forms resulted in a higher accumulation in muscle tissue compared to the inorganic Se form. No differences in meat quality characteristics were found among the experimental groups. It is concluded that Se from Se-enriched alga, Chlorella spp. had a lower accumulation in muscle tissue than Se from Se-enriched yeast, and it did not affect meat quality.

A study was made of the effects of barley feeds containing varying levels of natural grain selenium derived from fertilizer and of the effects of sodium selenite on selenium concentrations in the tissues of growing pigs and on the histological structure of myocardium and longissimus muscle. The results indicated that organic grain selenium affects the selenium levels of porcine tissues significantly more than sodium selenite supplementation of the same amount. The organic selenium concentrations of feed and organs were found to be linearly correlated. Spleen, lung and heart were the most reliable indicators of tissue selenium level in pigs. The selenium concentration of muscles of pigs fed on naturally seleniferous feed (270 µg Se/kg DM) was at the internationally level (500 µg Se/kg DM in meat), whereas the same amount of selenite in feed increased the selenium level of muscle only slightly (to 200/µg Se/kg DM). The histological structures of heart and muscle of pigs fed on naturally seleniferous feed were normal, whereas in the selenite group there were signs of muscle dystrophy when the selenium level was below 200 µg Se/kg DM. In addition, the pigs given selenite were subsequently placed in a lower, fat-containing carcass class. Feed with a natural organic selenium level of 150—200 µg Se/kg DM is preferred to selenite selenium supplement in pork production.

Live Yeast

The effect of a nutraceutical mixture, based on live yeast (LY), mannan oligosaccharides (MOS) and organic selenium (Se) on health status, as well as immune functionality and growth performance in the fattening of newly received beef cattle, was evaluated. A total of 1036 Charolaise heifers were allocated into two experimental groups: (i) control group, without any nutraceutical support (n = 487; initial weight = 325 ± 21 kg); and (ii) treatment group, supplementation during the first 30 days, with LY (5 g/head/day), organic Se (3 mg/head/day), and MOS (10 g/head/day) (n = 549; initial weight = 323 ± 23 kg). The incidence of bovine respiratory disease (BRD) and other health issues was monitored, as well as the mortality rate. Blood samples were taken at d0 and d30 to evaluate the immune functionality and the inflammatory status. Growth performances, feces chemical composition, and carcass characteristics were recorded. The BRD occurrence tended to be reduced (p = 0.06) in the Treatment group. The BHV-1 antibody production after vaccination was significantly improved (p = 0.031), as well as the bactericidal activity (p = 0.0012) in the Treatment group. No differences were found in the inflammatory status parameters. The final weight (p = 0.006) and the average daily gain at d30 (p < 0.0001) were significantly improved by the treatment. No differences were found in terms of carcass characteristics, while the fecal content of NDF (p < 0.0001), ADF (p = 0.0003), and starch (p < 0.0001) were significantly reduced by the treatment. The result of the present study suggests that the nutraceutical mixture used can support the animal’s immune systems, improving its ability to react against pathogens, as well as feed efficiency and growth performances during the whole fattening period.
