Productive performance and meat quality traits in growing rabbit following the dietary supplementation of Lippia citriodora , Raphanus sativus and Solanum lycopersicum extracts

Rabbit metabolic response and selected meat quality traits: Evaluation of dietary PLX®23 and LycoBeads®feed supplement

“…In addition, the TBARS values in Longissimus lumborum muscle of three experimental groups present a limited increase during the storage compared to the CON group, showing a lower rate of oxidation in the meat from 0 to 72 hr post‐mortem. This result agrees with previous research in rabbits supplemented with VB (Palazzo et al, ; Vizzarri et al, ) and with Peiretti et al () always in rabbits fed with dried tomato pulp, containing lycopene. Sahin et al () experienced in trout that lycopene is a powerful antioxidant able to protect tissues from oxidative damage and can be deposited in tissues exerting a powerful inhibitory effect on lipid oxidation.…”

“…The decrease in meat cholesterol content, found in three experimental groups, can be attributed to antioxidant effect exerted by the studied molecules, as already experienced in our previous work (Vizzarri et al, ), and by others authors (Kowalska & Bielański, ). In fact, carotenoids, similar to statins, increase LDL receptor activity and reduce the plasma concentration of cholesterol by acting as natural hypocholesterolemic agents.…”

“…Previous studies have indicated that the dietary supplementation with Verbenaceae natural extracts improves plasma oxidative profile both in weaned piglets (Pastorelli, Rossi, & Corino, ) and in rabbits does intensively reared (Casamassima et al, ), and enhances blood lipid profile in Lacaune sheep (Casamassima, Palazzo, Martemucci, Vizzarri, & Corino, ) and hares (Palazzo, Vizzarri, Cinone, Corino, & Casamassima, ). In our previous studies, performed in rabbit species for the evaluation of lycopene, verbascoside and horseradish effects supplemented in feed but not in combination among them (Vizzarri, Palazzo, D'Alessandro, & Casamassima, ), it was demonstrated the production of quality of meat with a lower saturated fatty acids, cholesterol and TBARS amount and a higher concentration in fat‐soluble vitamins (retinol and α‐tocopherol). Similar results on selected meat quality traits have been shown after the dietary supplementation with an extract of Lippia citriodora (with verbascoside as main component) in hare (Vizzarri, Nardoia, & Palazzo, ).…”

Adding palm oil to the diet of sheep alters fatty acids profile on yogurt: Benefits to consumers

“…In summary, these effects can be linked with the toxicity of unsaturated fatty acids (UFA) on ruminal microorganisms. Moreover, the increase on UFA and PFA content may be attributed to a significant increase of linoleic acid in the experimental groups, similarly to what was observed by Vizzarri et al (2017) in meat of rabbits supplemented with three different natural products, such as the extracts of Lippia citriodora, Raphanus sativus and Solanum lycopersicum. The action mechanism might be linked with the presence of linoleic acid, since it is a precursor of n3 and n6 UFA family, and the reactions of elongation and desnaturation are mediated by the enzymes fatty acil-CoA synthetases 6-and 5-desaturases, as well as by elongases (El-Shemy 2011).…”

Polyphenolic composition and antioxidant capacity of legume‐based swards are affected by light intensity in a Mediterranean agroforestry system

“…Casamassima et al . and Vizzarri et al . reported the supplementation of rabbit feeding with plant extracts, also based on verbascoside, with positive effects on blood parameters, plasma oxidative markers, productive performance and meat quality, as well as possible beneficial effects on animal health.…”
