Selenium or vitamin e mitigates hyperthermia in growing pigs

Abstract

¼ 0.0066, p ¼ 0.034, 25 nmol/L for FRT, b low ¼ 0.684 (0.075, 1.292); Db ¼ 0.697, p ¼ 0.027 and LMS, b low ¼ 1.703 (0.241, 3.165); Db ¼ 1.802, p ¼ 0.020, and 60 nmol/L for ST, b low ¼ 0.030 (-0.001, 0.061); Db ¼ 0.051, p ¼ 0.038. Conclusions:In middle-aged women, the point at which relationships between 25(OH)D and musculoskeletal outcomes change varies for different outcomes. The current cut-off of 50 nmol/L appears too high for some outcomes but reasonable overall to optimise bone and balance in this population.

Selenium and vitamin E together improve intestinal epithelial barrier function and alleviate oxidative stress in heat‐stressed pigs

“…prevented a decrease in bicarbonate in heat‐stressed pigs (Liu et al . ); however, the mechanism remains unknown. The haematocrit was unaffected in present experiment, although the pigs had free access to water.…”

ФИЗИОЛОГО-БИОХИМИЧЕСКИЕ ЭФФЕКТЫ ДВУХ КОРМОВЫХ АНТИОКСИДАНТОВ ПРИ МОДЕЛИРОВАНИИ ТЕХНОЛОГИЧЕСКОГО СТРЕССА У СВИНЕЙ (Sus scrofa domesticus Erxleben, 1777)

“…Возможность нивелировать у свиней последствия стресса (в част-ности, транспортного) за счет дополнительного введения селена в рацион была изучена в работе F. Liu с соавт. (40). При скармливании животным селена (от 0,24 до 1 мг/кг) на фоне витамина Е (17-100 мг/кг) у растущих свиней наблюдали снижение гипертермии (40).…”

Supplementation of selenium, vitamin E, chromium and betaine above recommended levels improves lactating performance of sows over summer

“…Three additional functional nutrients which have proved beneficial to reducing HS or improving lactational performance under thermoneutral conditions were added in a combination. Firstly, a supranutritional amount of Se (0.8 ppm) was added to further enhance glutathione peroxidase activity to reduce HS-induced oxidative stress, because a similar level of Se (1.0 ppm) supplementation was shown to ameliorate the physiological response to HS in pigs (Liu et al 2014). Secondly, yeast mannan oligosaccharides are immuno-modulators and improve immunity in disease challenged pigs (Che et al 2012), and thus it may regulate the HS-induced inflammatory response (Ganesan et al 2016).…”
