Supplementation of lentinan improves lactation performance by altering ruminal microorganisms and metabolites in dairy cows.

ABSTRACT: Lentinan (LNT) is a bioactive polysaccharide that has been proven to improve the production performance of animals. The objective of this study was to investigate the effects of LNT on lactation performance and rumen fermentation in dairy cows. Through random block design, 80 Holstein cows were randomly assigned to four treatments (CON, control group, fed a basal diet; and 5LNT, 10LNT, 15LNT groups, fed a basal diet with 5, 10, 15 g/d LNT, respectively) according to the days in milk (57 ± 21.3 d), milk yield (42.3 ± 7.88 kg/d) and parity (3.44 ± 1.45). Each treatment had 20 replicates of one cow each. The results showed that there was a linear increment in the production of milk (P = 0.034, increased by 3.28 kg/d), milk protein (P = 0.020, increased by 76.04 g/d) and lactose
