Dietary fat and its influence on rumen microbiota. Part II

Dietary fat and its influence on rumen microbiota.

This second entry, analyzes the results obtained by researchers in the in vivo trials previously mentioned. As well as delving in fat biohydrogenation with greater depth. A process that follows after lipolysis once fats are within the rumen, as it was previously described in the first entry.

 

Detoxifying adaptation-biohydrogenation

This process is considered as a detoxifying adaptation (Kemp et al. , 1984), and marginally contributes to the elimination of reducing equivalents produced by rumen fermentation (Lourenço, et al. 2010).

Biohydrogenation (BH) comprises several steps, depending on the USAFs, as well as several pathways, depending on diet and rumen environment (Griinari et al., 1998).

Protozoa encompass bacteria, and bacterial biohydrogenation can take place within protozoa (Jenkins et al., 2008) which explains their high concentrations of intermediate products (Devillard et al. , 2006).

In Vivo Studies

Beyond studies based on the selected isolates, in vivo trials have been carried out to evaluate the relationship between rumen bacteria and biohydrogenation. This has been done by  adding bacteria and quantifying their products, or by adding dietary supplements known to affect BH and measuring bacterial abundance.
