“…It is known that the phenolic concentrations in the whole YS plant are much lower than its bark (Oleszek et al, ). Hence, the even higher YSE dosage may continue to exhibit positive antioxidant functions to broilers as indicated by Gurbuz, Balevi, Kurtoglu, and Oznurlu (). Our results suggest that there is no need to increase the YSE level to broilers beyond the optimum, which we here found to be 100–200 mg/kg.…”

Dietary Yucca schidigera extract (YSE) could enhance immune function in broilers, which was attributed primarily to its saponin components. However, YSE also contains phenolic compounds which possess antioxidant ability. This study tested the effects of YSE on growth performance of broilers, its antioxidative enzyme activities and corresponding gene expressions in the small intestine. A total of 128 15‐day‐old broilers were randomly assigned to 4 treatments: corn‐soya bean meal as the basal control diet or the basal diet containing either 100, 200 or 300 mg/kg of YSE. Each treatment consisted of four replicate pens with eight broilers per pen. The experiment lasted 28 days which was divided into a grower period (day: 15–28) and a finisher period (day: 29–42). On day 28 and day 42 body weight (BW), feed intake (FI) and feed conversion rate (FCR) were recorded. Duodenum, jejunum and ileum were collected to analyse superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities, malondialdehyde (MDA) concentrations, total antioxidant capacity (T‐AOC) and gene expressions of SOD, CAT, GPx. The results showed that during the grower period a diet including 100 mg/kg YSE improved CAT capacity in the ileum, tended to increase activities of GPx in the duodenum, and further showed enhancing tendencies in SOD and GPx abilities in ileum. Gene expressions of CAT, SOD and GPx in the ileum tended to upregulate at 100 mg/kg YSE level. In the finisher period and over the whole period, all YSE groups had a reduced FI compared to the control group without compromising BW; 100 and 200 mg/kg YSE significantly improved FCR. In conclusion, the improved growth performance of broilers during the finisher period may be due to enhanced antioxidative ability in the grower period with YSE supplementation. This study provided evidence of using YSE as an additive to enhance growth in broilers.

“…The present study revealed no significant effects of feeding saponin rich SSP on the intestinal histomorphometry of broiler chicken. However, in contrast to these results greater villus height of jejunum and ileum was observed in layer chicken fed dietary Yucca schidigera extract (Gurbuz et al, ) and increase in villus height and crypt depth of duodenum and jejunum of Muscovy ducks was observed by feeding saponin rich alfalfa meal (Jiang et al, ). The variation in the results of saponin effects on intestinal mucosa in different studies may be due to the interaction of ingested saponins with many potential ligands in the intestine such as bile salts, dietary cholesterol, membrane sterols of the mucosal cells and nutrients or antinutrients present in feed, all of which may reduce or enhance their effectiveness.…”

“…The saponins from Yucca schidigera were found to have differential effects on gut microbes, whereby, the faecal E. coli growth in layer chicken is significantly inhibited with no effect on the Lactobacillus count (Wang & Kim, 2012). The improved gut architecture has been observed in layer chicken fed dietary Yucca schidigera extract (Gurbuz, Balevi, Kurtoglu, & Oznurlu, 2011) and in Muscovy ducks fed saponin rich alfalfa meal (Jiang et al, 2012). Thus, the addition of medicinal plant extracts to animal diets is not a new idea, and both Yucca and Quillaja saponins are commercially available products that have been used as feed additives.…”

This study was conducted to evaluate the effects of dietary soapnut (Sapindus mukorossi) shell powder (SSP), a cheap source of saponins, on growth performance, immunity, serum biochemistry and gut health of broiler chickens. The experimental design was 4×2, employing four saponin levels (0, 100, 150 and 200 mg/kg diet), each provided for two time durations (0–42 day and 21–42 day) resulting into eight dietary treatments. Results revealed no significant effect of dietary saponins on body weight gain, feed intake and feed conversion ratio of birds. The abdominal fat percentage, heterophil to lymphocyte ratio, serum cholesterol and triglyceride levels, faecal total plate count, coliform count and E. coli count decreased (p < .05) progressively with increasing saponin levels and lower values were observed at 150 mg and 200 mg saponin levels. Significant improvement of cell‐mediated and humoral immune response was observed in birds fed 150 mg and 200 mg saponin compared to control. The serum glucose concentration was significantly (p < .05) higher in control group compared to other groups. No significant effects of dietary saponin were observed on carcass characteristics, faecal Lactobacillus count, intestinal histomorphometry and cost economics of broiler chicken production. Thus, dietary saponins at 150 mg/kg diet as SSP for three weeks (21–42 days) was optimum for better immunity and welfare of birds without adverse effects on the growth performance.

“…Enhances bird's growth and production, improves the metabolic efficacy, decreases the ammonia level, and increases the feed utilization in production of broilers (Sahoo et al, 2015). Significant increase in weight was recorded in the Yucca treated groups when compared to yeast cell walls and Yucca schidigera extraction in the diet of chickens (Gurbuz et al, 2011). The 38% reduction in ammonia was observed by using commercial preparation of Yucca schidigera (Karamanlis et al, 2008).…”

The study was carried out on 100 broiler birds to ascertain the effect of ammonia and different ammonia modifiers on various parameters. For this purpose, the birds were divided into five groups and different treatments were allotted including potassium aluminium sulphate, aluminium silicate and Yucca schidigera plant extract. A completely sealed environment was created to produce ammonia. Results showed that ammonia at 25 ppm did not affect the carcass weight, relative organs weight and antibody titer. Gross and histopathological changes like pale liver, congestion in lungs and necrosis in kidneys were observed in positive control group, while minor changes were seen in all treatment groups. Grossly, bursa of Fabricious appear smaller in size, while on histological examination it showed depletion of lymphocytes in positive control. The level of urea (18.53 mg/100 ml), creatinine (0.30/ mg/100 ml), AST (53.0 IU/L) and ALT (7.50 IU/L) were increased. The antibody titer (5.65 log 2 ) was not affected by 25 ppm of ammonia however, it was 35% higher than both the control groups in aluminium silicate group (7.67 log 2 ). A lower spleen weight (0.10 g) and kidney (0.73g) weight, while higher levels of urea (15.83 mg/100 ml) and creatinine (0.31 mg/100 ml) were observed in Yucca treated groups. The AST (53 IU/L) and ALT (8.26 IU/L) were found significantly (P<0.05) higher in alum treated groups than both control groups. All the treatments reduced the effects of ammonia in broilers, however, in overall aluminium silicate results were better than other treatments. The study concludes that, all the three amendments are useful in reducing the ammonia and improves the production and function of the broiler chicken.
