Effects of Yucca Extract on Feed Efficiency, Immune and Antioxidative Functions in Broilers

Abstract

Effects of yucca extract (YE) on feed efficiency, immune and antioxidative function in

Effects of Liquid Yucca Supplementation on Nitrogen Excretion, Intestinal Bacteria, Biochemical and Performance Parameters in Broilers

“…Also, the levels of IgM and G revealed that yucca had an immunostimulant effect in broilers. Similar findings were obtained by Su et al [29], who found that dietary supplementation of 100 ppm Y. schidigera powder increased IgG, and induced IgM. At a level of 200 ppm, a better effect on cellular and humoral immune responses in broilers was seen.…”

“…Previous research has demonstrated that saponin can improve the absorption of nutrients from the intestinal tract [28]. These results are supported by those of Su et al [29], who found that dietary supplementation of Y. schidigera powder at a level of 100 ppm improved body weight gain and feed efficiency during the finisher period. In line with these results, Sahoo et al [30] found that yucca supplementation could effectively lead to a better feed conversion rate and protein efficiency ratio, than in an un-supplemented group.…”

“…Regarding antioxidative biomarkers, results in Table 5 confirmed that the addition of yucca improved the activity of antioxidant enzymes including SOD, CAT, and GSH, and decreased lipid peroxidation biomarkers compared to the control group. Similarly, Su et al [29] demonstrated that broiler chickens fed yucca showed a significant improvement in SOD activity, and exhibited a strong antioxidative effect. Yucca is a good source of many phytochemicals like resveratrol and other bioactive components, such as yuccaols (A, B, C, D, and E) [10,11].…”

Effect of dietary saponin rich soapnut (Sapindus mukorossi) shell powder on growth performance, immunity, serum biochemistry and gut health of broiler chickens

“…Similarly, the enhanced immune responses to vaccination against Newcastle disease, Avian influenza and Infectious bursal disease was observed due to saponin supplementation in broiler chicken (Zhai et al, ; Zhai, Wang, Yu, & Hu, ). Also, the dietary yucca extract (containing saponin) supplementation was to have no significant effect on the weight of immune organs (spleen, bursa and thymus) in broiler chicken (Su et al, ). However, in contrast the dietary supplementation of polysavone (Alfalfa extract) in broiler chicken significantly improved immune organ weights (Dong et al, ).…”

“…However, results have shown considerable variations and thus, the role of saponins in growth performance of chicken remains largely inconclusive. The saponins from Yucca schidigera, ginseng and tea plants have shown immunomodulatory effects in chicken (Bhardwaj et al, 2014;Zhai, Li, Wang, Wang, & Hu, 2011) with higher immunoglobulin levels and positive effects on immune organ maturation (Su et al, 2016).…”
