Effects of selenium yeast on rumen fermentation, lactation performance and feed digestibilities in lactating dairy cows
The objective was to evaluate the effects of selenium-yeast (SY) supplementation on rumen
fermentation, lactation performance and feed digestibilities in dairy cows. Twenty-eight
multiparous (2.5±0.3 parity) Holstein dairy cows, averaging 625±18.2 kg of BW, 63±3.0 days
in milk and average daily milk production of 26.2±0.5 kg/cow were used in a replicated 4× 4
Latin square experiment. Treatments were: control, LSY, MSY and HSY with 0, 150, 300 and
450mg selenium yeast (Sel-Plex®, 1g/kg selenium, produced from Saccharomyces …
