Abstract

The purpose of this experiment was to investigate the effects of kelp powder as a feed ingredient on rumen fermentation parameters and microflora structure of dairy cows fed a high concentrate diet. Fifty healthy lactating cows in the middle and late lactation with the body weight of (605±36) kg were randomly divided into 3 groups with 5 cows per group. Using a randomized trial design, cows in the 3 groups were fed 45% low concentrate diet, 55% high concentrate diet and 55% high concentrate+5% kelp powder diet, respectively. The experiment period was 35 days. At the end of the test, the rumen liquid was collected from the cows before the morning feeding, and the pH, ammonia nitrogen, microbial protein, volatile fatty acid concentrations and microflora structure were determined. The results showed as follows:1) compared with the 55% high concentrate diet, the pH of rumen was significantly increased (P<0.05), the concentrations of ammonia nitrogen and microbial protein were significantly reduced (P<0.05), and the concentration of total volatile fatty acids and the percentages of butyric acid, isobutyric acid and isovaleric acid in volatile fatty acids were significantly increased after adding 5% kelp powder into the 55% high concentrate diet (P<0.05). 2) Adding 5% kelp powder into the 55% high concentrate diet reduced the unique operational taxonomic unit (OUT) number of samples, but had no significant effect on the rumen bacterial α diversity (P>0.05). At the phylum level, the 55% high concentrate diet significantly increased the relative abundance of Actinobacteria in rumen (P<0.05), and significantly reduced the relative abundance of SR1_Absconditabacteria in rumen compared with the 45% low concentrate diet (P<0.05); after adding 5% kelp powder into the 55% high concentrate diet, the relative abundance of Bacteroides in rumen was significantly decreased (P<0.05), the relative abundance of Firmicutes in rumen was significantly increased (P<0.05), and the relative abundance of Actinomycetes in rumen was further increased (P<0.05). At the genus level, the 55% high concentrate diet significantly increased the relative abundances of Ruminococcus_2 and Lachnospiraceae_NK3A20_group in rumen (P<0.05), and significantly reduced the relative abundances of Prevotella_1 and Prevotellaceae_UCG-003 in rumen compared with the 45% low concentrate diet (P<0.05); adding 5% kelp powder into the 55% high concentrate diet further significantly reduced the relative abundance of Prevotella_1 and significantly increased the relative abundance of Ruminococcus_2 in rumen (P<0.05). In summary, adding 5% kelp powder into the 55% high concentration diet can improve the rumen fermentation environment of dairy cows, and adjust the structure of rumen microflora, which has little effect on rumen bacterial diversity.
