Supplementation effects of seleno-compounds, carnosic acid, and fish oil onconcentrations of fatty acids, tocopherols, cholesterol, and amino acids in the livers of lambs

Selenium supplementation into diets containing carnosic acid, fish and rapeseed oils affects the chemical profile of whole blood in lambs

“…Thus, our study supports the finding that dietary CA stimulated the biosynthesis of aldehydes (i.e. volatile species from lipid autoxidation) in selected tissues of lambs (Morán et al, 2013;Rozbicka-Wieczorek et al, 2016c). On the other hand, lower levels of CA (≤ 0.6 g · kg −1 ) stimulated an antioxidant effect in tissues closer to that observed in lambs fed diets supplemented with vitamine E (Morán et al, 2013).…”

“…Similarly to Se-supplemented diets, the experimental diet with only CA addition reduced the bioaccumulation of ΣFA, including ΣSFA and especially ΣLPUFA, in whole blood in comparison to the control diet. This CA supplemented diet more effectively reduced the concentration of VFAs (especially acetic acid) in the rumen as compared to the control diet as well as ∆4-index (Table 5) in comparison to the control and other experimental diets (Rozbicka-Wieczorek et al, 2016c).…”

Selenium species in diet containing carnosic acid, fish and rapeseed oils affect fatty acid profiles in lamb muscles

“…In fact, acetic acid is the major source of acetyl-CoA for biosynthesis of lipids; acetic acid is oxidized almost throughout the whole body to generate adenosine triphosphate (ATP), whereas butyric acid is oxidized in many tissues for energy production (Berg et al, 2002). Therefore, we argued that the lowest concentration of VFA in ruminal fluids of lambs fed the SeVI diet is responsible for the smallest concentration of FA in and ( Rozbicka-Wieczorek et al, 2016). So, current study documented that the feeding lambs SeVI in contrast to SeY did not increase the concentration of FA in and MBF and so not differ from the control group.…”

Effects of Fish Oil and Dietary Antioxidant Supplementation on Bone Health

“…Moreover, according to Rozbicka-Wieczorek et al [9], such a dietary supplementation decreased oxidative processes in the animal body. Oxidative stress disrupts bone remodelling, consequently reducing bone mass and bone density and increasing bone susceptibility to fractures [19].…”

“…Thus, dietary supplementation of n-3 PUFA in monogastric animals is beneficial for both animals (by improving their welfare) and humans (by improving the composition of animal products, such as meat). Recently, much scientific efforts was put into the modification of fatty acid profile of ruminant tissues [5,8,9]. However, achieving benefits in this group of animals is rather difficult due to differences in the structure of the gastrointestinal tract.…”
