Dietary supplementation of Butyrivibrio fibrisolvens alters fatty acids of milk and rumen fluid in lactating goats

Abstract

Results of the present study indicated that administration of B. fibrisolvens In-1 along with a linoleic acid (LA) source is a useful strategy to alter the biohydrogenation pattern in the rumen that subsequently decreased SFA content while increased CLA and unsaturated fatty acids in ruminant's milk.

Rumen microbiota and dietary fat: a mutual shaping

“…Beyond studies based on the culture of selected isolates, attempts have been made to assess in vivo or in vitro the relationship between rumen bacteria and BH by adding bacteria and measuring BH products, or by adding dietary supplements that are known to affect BH and measuring bacteria abundance. Inoculating B. fibrisolvens into the rumen of goats fed a diet enriched with a high LA oil increased VA and total CLA concentrations in the rumen fluid, which confirms that this bacterium is involved in BH in vivo (Shivani et al 2016). Long-chain PUFAs from fish oil or marine algae are known to lower the reduction from VA to stearic acid, and because B. proteoclasticus is the only well-characterized stearate producer, it can be hypothesized that these supplements affect B. proteoclasticus abundance.…”

“…() postulated that some strains of B. fibrisolvens could be used as a probiotic to better control FA resulting from BH in animal products, but only Shivani et al . () tested this supplementation, obtaining time‐dependent effects. Apás et al .…”

“…Inhibition of ruminal lipase-producing bacteria using an antilipase antibody affected several lipase-producing bacteria, including B. fibrisolvens, and decreased BH in vitro (Edwards et al 2017). Fukuda et al (2006) and Fukuda et al (2009) postulated that some strains of B. fibrisolvens could be used as a probiotic to better control FA resulting from BH in animal products, but only Shivani et al (2016) tested this supplementation, obtaining time-dependent effects. Ap as et al (2015) showed an increased proportion of cis-9, trans-11-CLA in the milk of goats supplemented with a mixture of Lactobacillus, Bifidobacterium and Enterococcus.…”

Review: Modulating ruminal lipid metabolism to improve the fatty acid composition of meat and milk. Challenges and opportunities

“…Information is still very limited, but encouraging results (i.e. increased milk t11-18:1 and c9t11-CLA concentration) have been shown in goats fed strains of Butyrivibrio fibrisolvens (Shivani et al, 2016), Lactobacillus plantarum (Maragkoudakis et al, 2010) and a mixture of Lactobacillus reuteri, Lactobacillus alimentarius, Enterococcus faecium and Bifidobacterium bifidum (Apás et al, 2015). Greater milk 18:2n-6 and 18:3n-3 proportions were also found in the two latter studies.…”
