Naringin supplementation affects performance, carcass traits, meat quality and oxidative stability of finishing pigs

Abstract

Naringin is a major flavanone derivate that has many important biological functions in animals. However, its effect on pigs is unknown. The aim of this study was to investigate the effect of naringin supplementation on performance, carcass traits, meat quality and oxidative stability in finishing pigs. Ninety-six pigs, with an average initial body weight of 66.2 ± 0.63 kg, were randomly divided into four groups. One group was fed a basal diet without supplementation (control), and the three others were fed diets supplemented with 0.5, 1.0 or 1.5 g naringin /kg DM of feed for 50 days. Each treatment was replicated six times with four pigs per replicate. Feed and water were available ad libitum. The 0.5 g/kg naringin treatment group had an improved loin eye muscle area, reduced serum triglycerides and were leaner compared with the other groups. Pigs in the 1.5 g/kg naringin treatment had higher pH45min values and inosine monophosphate concentrations, and lower MyHC IIb mRNA expression in muscle than the other groups. MyHC IIa mRNA expression was significantly up-regulated in all naringin-supplemented diet groups. Naringin significantly increased superoxide dismutase (SOD) activity and total anti-oxidative capacity in meat, as well as SOD and glutathione peroxidase activity in the liver. These results indicate that the dietary addition of naringin at 0.5 g/kg improved carcass characteristics, while 1.5 g/kg improved the oxidative stability and pork quality in finishing pigs.

Therapeutic potential of naringin in improving the survival rate of skin flap: A review

“…Naringin could scavenge free radicals and increase SOD and glutathione peroxidase activity in vivo by regulating the expression of antioxidant defense proteins (Hager-Theodorides et al, 2021). Naringin exerts its total antioxidant capacity in the body through its activity (El-Desoky et al, 2018;Wang et al, 2020). Naringin improved coronary ischemia-reperfusion injury in rats by scavenging free radicals and antioxidant properties (Liu et al, 2022), and it was also protective against ischemia-reperfusion-induced oxidative stress in rat testes (Akondi et al, 2011).…”
