Aims: The effects of partial replacement of a barley-based concentrate with flaxseed-based products on the rumen bacterial population of lactating Holstein dairy cows were evaluated. Methods and Results: Treatments fed were CONT, a normal diet that included barley silage, alfalfa hay and a barley-based concentrate that contained no flaxseed or faba beans; FLAX, inclusion of a nonextruded flaxseed-based product containing 55Á0% flaxseed, 37Á8% field peas and 6Á9% alfalfa; EXT, similar to FLAX, but the product was extruded and EXTT, similar to FLAX, but product was extruded and field peas were replaced by high-tannin faba beans. The rumen bacterial population was evaluated by utilizing 16S rRNA gene sequencing. Most abundant phyla, families and genera were unaffected. However, some taxa were affected; for example, unsaturated fatty acid content was negatively correlated with Clostridiaceae, and tannin content was negatively correlated with BS11 and Paraprevotellaceae. Conclusions: Predominant rumen bacterial taxa were not affected, but the abundance of some taxa found in lower proportions shifted, possibly due to sensitivity to unsaturated fatty acids or tannins. Significance and Impact of the Study: Flaxseed-based products were effective for partially replacing barley-based concentrate in rations of lactating dairy cows. No negative effects of these products were observed on the abundance of predominant rumen bacterial taxa, with only minor shifts in less abundant bacteria.

“…Kruskal-Wallis tests adjusted for multiple comparisons were used to confirm the significance of these indicator species. The co-occurrence network analysis was used to examine the existence of true correlations among the milk bacteria across all three hosts according to our previous method51. In general, spearman’s rank correlations and p -values were calculated and plotted using the hmisc and corrplot packages.…”

Lactation provides the singular source of nourishment to the offspring of mammals. This nutrition source also contains a diverse microbiota affecting the development and health of the newborn. Here, we examined the milk microbiota in water deer (Hydropotes inermis, the most primitive member of the family Cervidae), reindeer (Rangifer tarandus, the oldest semi-domesticated cervid), and the dairy goat (Capra aegagrus, member of the family Bovidae), to determine if common milk microbiota species were present across all three ruminant species. The results showed that water deer had the highest bacterial diversity, followed by reindeer, and then goat. Unifrac distance and correspondence analyses revealed that water deer harbored an increased abundance of Pseudomonas spp. and Acinetobacter spp., while milk from reindeer and goat was dominated by unclassified bacteria from the family Hyphomicrobiaceae and Bacillus spp., respectively. These data indicate significant differences in the composition of milk-based bacterial communities. The presence of Halomonas spp. in three distinct co-occurrence networks of bacterial interactions revealed both common and unique features in milk niches. These results suggest that the milk of water deer and reindeer harbor unique bacterial communities compared with the goat, which might reflect host microbial adaptation caused by evolution.

“…Besides, ionosphere feed additive namely saponins and tannins is coming to deserve attention as antimicrobial properties. Li, et al [12], ability of tannin supplementation had a broadly distortion of rumen microbiota, thereby being useful to shift rumen performance. Another, saponins concerned to inhibit methane emission and lower biohydrogenation because of defaunation function leading to protozoa-lipid population decrease [9].…”

20This meta-analysis was conducted to predict and assert a way to discover conjugated 21 linoleic acid (CLA) formation in ruminant-derived products as problem solver of human health 22 issues threated by plant-containing tannins. The objective was to expound, to compare, and to 23 confirm the efficiency of tannins cultivating CLA formation whether using in vitro and/or in 24 vivo study. A database was created using the ruminants with selectively 26 experiments 25 comprising 683 dietary treatments as explained in vitro and in vivo methods that were applied 26 as a statistical SAS 9.4 tool. Basically, increasing level of tannins leaded to an underlying 27 decrease in CLA formation (p<0.001), initially at predicting coefficient determination 28 R 2 =0.193, R 2 =0.929, and R 2 =0.549 for CLA in vitro, in vivo of CLA milk shift, and in vivo of 2 29 CLA meat precipitation, respectively. In vitro may accurately predict to the in vivo observation. 30 Unfortunately, there were no relationship in vitro towards in vivo observation (R 2 <0.1). It 31 indicated to be difficult to predict CLA from in vitro to in vivo separately situations. According 32 to all studies, the level of tannin's utilization for inhibiting biohydrogenation was not 33 exceedingly >50 g/kg DM recommended. Secondly, the in vivo method was more suitable for 34 directly observation that concerned in fatty acid transformation. 35 36 42cholesterol level, which is a risk factor for coronary heart disease. In previous studies, have 43 been coined conjugated linoleic acid (CLA) as natural fatty acid (FA) and this FA could solve 44 aforementioned human problems [1][2][3]. The predominant isomer of CLA is cis-9, trans-11 18:2, 45 representing 75-90% of the total CLA in ruminant fat, and trans-7, cis-9 CLA is the second 46 most prevalent isomer at 3-16% of the total CLA [1, 4] and the trans-11, 18:1 (vaccenic acid) 47 existence is notable know to support cis-9, trans-11 18:2 [3]. However, producing CLA in milk 48 and meat is quite difficult because its process invites biohydrogenation respecting to 49 catalyzation by ruminal microorganisms. For instance, Butyrifibrio fibrisolvens was identified 50 to undertake biohydrogenation of FA and to carry in creating cis-9, trans-11 18:2 and trans-11 51 18:1 by way of trans-11 18:2 (n-6) [5, 6]. Thus, bacteria acts the fundamental role in FA 52 biohydrogenation [7] and looking for alternative feed additives from Phytochemicals [8] as anti-53 microbial could be greater option to increase CLA in ruminant products. 3 54 Essential oils are commonly supplementation derived from plant and marine product. 55 Their function exactly had many modes bringing ruminal bacteria N down [9] and inhibited 56 survival of Butivibrio fibrisolvens and Butivibro proteoclasicus community on 57 biohydrogenation[10]. The effective of essential oils had variable impacts on ruminal 58 fermentation [11], it might be believed in depend on source extraction, method, dose, basic diet, 59 pH and preliminary period of microorganism to adapt ess...
