“…of C18:2n6c but a high concentration of C18:1n9t. These observations agree with Dai et al (2017) who reported that dietary α-linolenic acid increases the relative abundance of Selenomonas ruminantium, and with Polan et al (1964) who reported that Selenomonas plays an important role in forming C18 monoenoic acid.…”

This study investigated the effects of dietary supplementation with alternative sources of α-linolenic acid on growth, the composition of rumen microbiota, and the interactions between rumen microbiota and long-chain fatty acid (FA) concentrations, in goat kids. Sixty 4-monthold castrated male Albas white cashmere kids (average BW 18.6 ± 0.1 kg) were randomly allocated among three dietary treatments: (i) basal diet without supplementation (Control), (ii) basal diet supplemented with linseed oil (LSO), (iii) basal diet supplemented with heated linseed grain (HLS). The concentrate:forage ratio was 5:5 and the LSO and HLS treatments provided the kids with similar dietary FA profiles. The diets were fed for 104 d, consisting of 14 d for adaptation followed by 90 d of experimental observation. Treatment did not significantly influence BW, DMI, or bacterial richness or diversity. On the other hand, the relative abundance of bacteria participating in hydrogenation differed significantly among the three groups: the Veillonellaceae and Christensenellaceae were more abundant in LSO kids, Prevotellaceae were more abundant in HLS kids, and the Fibrobacteriaceae were more abundant in Control kids (P < 0.05). Spearman correlation analysis indicated that Ruminobacter, Selenomonas_1, Fretibacterium, Prevotellaceae_ UCG-001, Succinimonas, and Ruminococcaceae_ NK4A214_group were the genera that participated in hydrogenation of long-chain FAs. HLS-fed kids had a lower relative abundance of Ruminobacter, but a higher abundance of Prevotellaceae_UCG-001 and Fretibacterium than LSO-fed kids. These changes were associated with greater rumen concentrations of C18:3n3 and n-3 PUFA, but lower concentrations of n-6 PUFA and lower n-6/n-3 ratios, in HLS than in LSO-fed kids. In conclusion, feeding kids with HLS increased rumen concentrations of C18:3n3 and n-3 PUFA, but decreased the n-6/n-3 ratio by decreasing the abundance of bacteria that hydrogenate C18:3n3 and increasing the abundance of bacteria that hydrogenate C18:2n6.

As the importance of gut microbiota in health is increasingly recognized, the interest in interventions that can modulate the microbiota and its interactions with its host has soared. The survival status of the probiotics in the gastrointestinal environment and the microbial interactions between the LAB have also received considerable attention. In the present research, the gastrointestinal environment tolerance, adhesion ability, and biofilm formation of the lactobacillus strains in the co-culture system were explored, through the real-time fluorescence-based quantitative PCR, UPLC-MS/MS metabolic profiling analysis and Live/Dead® BacLightTM cell staining methods. The results show that the co-culture system can promote the release of signal molecules and can effectively protect the liability of the Lactobacillus acidophilus in the gastrointestinal environment. Meanwhile, amino acid-derived quorum sensing molecule L-alanine (1 %) can effectively enhance the communication of the cells in the complex fermentation model, which leads to the increase of the liability of the L. acidophilus in the gastrointestinal environment.
