Effect of yerba mate (Ilex paraguariensis) in lamb diets on fatty acid profile, physical and sensory characteristics of the Longissimus muscle

Fatty acids composition, lipids health indices and enzyme activities of longissimus thoracis muscle of six breeds of sheep produced on pasture in Northern region of Uruguay

“…No differences between the breeds studied in this work were detected. The range of BCFAi observed in our work was of the same order that those reported by Gomez-Cortes et al [35] and Mele et al [37], but higher to the values reported by Pena-Bermudez et al [36]. Note that in those three reports the lambs were fed concentrate.…”

“…There were not differences between the breeds studied in our work (TABLE IV). That range was in the same order of levels reported by Mele et al [37], slightly higher to values of Garcia et al [28], but markedly higher in comparison to values reported by Gomez-Cortes et al [35] and Pena-Bermudez et al [36]. As indicated before, the lambs used in the works of Mele et al [37], Gomez-Cortes et al [35] and Pena-Bermudez et al [36] were fed concentrate, while the lambs in the work of Garcia et al [28] were fed shrub grass steppes.…”

“…For BCFAai the range observed was between 0.52-0.73 g•100 g -1 of fatty acids, and RM presented a higher content than MD (TABLE IV). The range of BCFAai observed here is of the same order than those reported by Mele et al [37], but higher than those reported by Gomez-Cortes et al [35] and Pena-Bermudez et al [36]. Certainly, the explanation presented before that in the rumen the interrelation between the microbial populations, the specific fatty acids synthetases and the composition of pasture regarding fatty acids and amino acids leading to the different kind of BCFA in meat could be introduced newly here.…”

“…There are not differences between the breeds studied in our work. That range of values was slightly higher than those reported by Gomez-Cortes et al [35] and Pena-Bermudez et al [36], but slightly lower than those presented (control group) by Mele et al [37]. In the three mentioned experiments the animals were fed concentrate and the expression of results was as g•100 g -1 fatty acids.…”

Potential modulating effects of Allium mongolicum regel ethanol extract on rumen fermentation and biohydrogenation bacteria of dairy cows in vitro

“…This may be related to the regulation effect of PE on rumen fermentation and BH. Diet supplementation with compound phenolic enriched yerba mate extracts resulted in less BH time, which increased the content of polyunsaturated fatty acid (PUFA) deposited in lamb tissues (Pena-Bermudez et al, 2022). Another study pointed out that supplementation of essential oil from anise increased ruminal pH and increased UFA concentrations in the rumen (El-Essawy et al, 2021).…”
