A new selenium source from Se-enriched Cardamine violifolia improves growth performance, anti-oxidative capacity and meat quality in broilers

Abstract

BackgroundCardamine violifolia (Cv) is a kind of selenium-enriched plant which contains high levels of organic selenium (Se) such as selenocysteine and methylselenocysteine. This study was conducted to investigate the effects of this new source of Se on the growth performance, anti-oxidative capacity and meat quality in broilers compared with other frequently-used Se sources.MethodsA total of 240 broilers were allotted into 4 treatments: (1) Control group (Se free diets, CON); (2) Sodium selenite group (0.3 mg/kg Se sourced from Na2SeO3 diets, SeNa); (3) Selenium yeast group (0.3 mg/kg Se sourced from Se-Yeast diets, SeY); (4) Plant Se group (0.3 mg/kg Se sourced from Cv diets, SeCv). The whole study lasted 42 days and was divided into 2 stages (1–21 d as earlier stage and 22–42 d as later stage).ResultsThe results showed that the broilers fed SeCv diets had improved average daily gain and the ratio of feed to gain compared to the broilers fed SeNa and SeY diets during the earlier stage. However, there was no significant difference in growth performance of broilers fed these 3 sources of Se diets during the whole period. The broilers fed SeCv diets had improved intestinal mucosal morphology on d 21 and 42. Enhanced liver total anti-oxidative capacity was observed from the broilers fed SeCv diets compared with the other 2 Se sources diets on d 21. Furthermore, lower liver malondialdehyde contents were determined from the broilers fed SeCv and SeY diets compared with SeNa diets. At last, the broilers fed SeCv had increased redness in thigh muscle and decreased cooking loss in both breast and thigh muscle compared with the boilers fed SeNa diets. However, the broilers had similar meat quality between SeCv group and SeY group.ConclusionIn conclusion, these results demonstrated that SeCv was a well-organic Se source for broilers.

Dietary Se-Enriched Cardamine enshiensis Supplementation Alleviates Transport-Stress-Induced Body Weight Loss, Anti-Oxidative Capacity and Meat Quality Impairments of Broilers

“…Our study showed that dietary SeCe supplementation alleviated transport-stress-induced meat quality reduction of breast and thigh muscle in broilers. In agreement with our results, other studies have reported the better effect of SeCe on meat quality of broilers compared with Na 2 SeO 3 [ 12 , 13 ]. The reason may be that Se increases oxidation resistance and prevents muscle protein being oxidized [ 39 ].…”

“…A previous study demonstrated that organic Se had higher anti-oxidative capacity compared with inorganic Se [ 34 ]. SeCe is a hyperaccumulating plant newly discovered in China and the Se mainly exists in SeCe in the organic form of SeCys 2 and MeSeCys [ 12 ]. The better effect of dietary SeCe supplementation on anti-oxidative capacity of broilers under transport stress may be due to the form of organic Se occurring in SeCe.…”

“…Studies have shown that Se-enriched C. enshiensis (SeCe) modulates oxidative stress and gut microbiota in D -galactose-injected mice [ 11 ]. Our previous studies found that SeCe improved growth performance and meat quality in broilers compared with Na 2 SeO 3 and Se-enriched yeast [ 12 ]. Additionally, SeCe had better effects on enhancing anti-oxidative capacity and meat quality of LPS-injected broilers compared with Na 2 SeO 3 [ 13 ].…”

Evaluation of Dietary Inorganic and Organic Selenium Sources on Immune Organ, Plasma Immunoglobulins, Blood Biochemical, and Performance of Broilers: A Meta-Analysis

“…The supplemental Selenium Yeast in organic trace minerals can support the highest growth of broiler chicks (Arnaut et al, 2021;Wang et al, 2021;Bakhshalinejad et al, 2018). In addition, Xu et al (2022) reported that a new source of selenium-enriched plants with high levels of organic Se is an acceptable Se source for broilers. In contrast, the average growth performance of broilers supplemented with organic selenium is lower than those supplemented with inorganic selenium.…”

Effects of Supplementing Selenium-Enriched Cardamine violifolia to Laying Hens on Egg Quality and Yolk Antioxidant Capacity during Storage at 4 °C and 25 °C

“…The Se concentration in the leaves of Se-enriched Cardamine violifolia (SEC) is greater than 700 mg/kg (dry weight), with over 85% of the complete Se deposited in the form of organic Se, such as selenocysteine and methylselenocysteine [ 17 ]. Our previous study indicated that dietary SEC supplementation enhanced the growth performance and antioxidant capacity of broilers [ 18 ]. Few studies have been performed to estimate the effects of SEC supplementation in a hen’s diet on egg quality during egg storage.…”
