“…Previous studies have shown that QY improves performance responses of broilers reared under the stress of intestinal disease challenge (Bafundo et al 2020). Trial results indicated that at least part of this effect was associated with a lower level of coccidiosis in birds receiving QY.…”

“…Recent research has shown that QY can impair the development of Eimeria spp. that damage the mucosal surface and adversely affect broiler performance (Bafundo et al 2020). As has been shown in numerous studies, even subclinical levels of coccidial infection impair the ability of enterocytes to function effectively, resulting in reduced nutrient digestibility and depressed bird performance (Arczewska-Wlosek and Swiatkiewicz 2014; Rochell et al 2016).…”

“…Typhimurium, Escherichia coli, and Staphylococcus aureus and other Gram-positive organisms has been described (Hassan et al 2010). Additionally, recent work has shown that a combination of quillaja and yucca saponins (QY) exerted anticoccidial effects in growing broilers (Bafundo et al 2020). Results demonstrated that oocyst production and lesion scores were reduced by QY alone, and when combined with other anticoccidial agents, disease prevention and production performance were enhanced.…”

1. Two series of studies were conducted to determine the effects of a combination of ground plant material derived from Quillaja saponaria trees and Yucca schidigera plants (QY) as sources of saponin, on performance, productivity, nutrient digestibility and ileal morphology of growing broilers. In each trial, 480 Cobb male birds were allocated equally to 24 pens at one-day-of-age according to body weight 2. The studies consisted of two identical floor pen trials in which performance and nutrient digestibility were assessed and two trials where performance and ileal morphology were determined. In each trial, 0, 250 or 500 ppm QY were included in feed given to the broilers from 1-35 or 1-42 d of age, respectively. Eight (digestibility) or 12 (morphology) randomised replicate pens were used. 3. In the digestibility trials, two birds per pen were moved to metabolism cages at d 21. Excreta was collected for a five-day period (d 21 to 25) for the determination of apparent total tract digestibility of dry and organic matter, fat and ash and nitrogen retention. For intestinal morphology, ileal segments were collected from four birds/pen on d 21 to determine villus height and crypt depth. Performance data were collected in each trial series. 4. Results showed that feeding graded levels of QY produced significant linear improvements in performance and productivity at d 35, and similar linear effects were observed for N retention and all apparent digestibility measurements. Morphology data showed that birds receiving 250 and 500 ppm QY had significantly increased villus height 5. These results indicated that QY exerted a positive influence on the intestinal tract by increasing the absorptive surface and improving nutrient digestibility. These effects were considered to be associated with the performance improvements recorded in both experiments.

“…Reports describing their effects on Eimeria spp. and improved performance of coccidia-vaccinated broilers are recent evidence of these responses ( Bafundo et al., 2020 ; 2021a ).…”

“…However, damage to the intestinal mucosa also impairs nutrient absorption ( Rochell et al., 2016 ; M'Sadeq et al., 2015a ), and as a result, carcass and parts yield are also affected ( Oikeh et al, 2019 ; Ahiwe et al, 2019 ). Because recent research has shown that a saponin combination of quillaja and yucca ( QY ) impaired the development of Eimeria and reduced mortality associated with NE infections in broilers ( Bafundo et al., 2020 ; 2021b ), further investigations into the effects of QY on carcass yield were warranted. Thus, the objectives of the current research were to determine whether graded levels of QY (0, 250, and 500 ppm) would improve performance and carcass yield of coccidia-vaccinated broilers reared under an intestinal disease challenge produced by Eimeria spp.…”

A series of 6 floor pen trials was conducted to determine the effects of a quillaja and yucca combination product on the performance and carcass traits of growing broiler chickens vaccinated for coccidiosis at the hatchery. In each of the trials graded levels (0, 250, and 500 ppm) of a quillaja and yucca combination ( QY ) were fed to Ross 708 broilers for the duration of each 42 d test. Trials were arranged in completely randomized block designs involving a minimum of 11 blocks per trial. At the start of each trial, pens contained 55 broilers. In order to provide each bird with an enteric disease challenge, 5 kg commercial broiler litter containing 10 4 CFU Clostridium perfringens per gram was placed in each pen. In addition, the sporulated oocysts of Eimeria acervulina and E. maxima were added to each pen at the outset of each test. At d 21 of the trials, coccidial lesion scores, mortality and performance were determined; final performance and total mortality were assessed at 42 d. At the completion of each test, 10 birds of average body weight per pen were selected for carcass evaluations; whole and chilled carcass yield were determined, and pre- and post-chill breast measurements were made. A combined analysis of the results of the 6 trials (75 replications per treatment) was used to determine treatment effects and each variable was assessed by linear regression analysis. Results indicated that QY significantly reduced mortality and coccidial lesions scores at d 21 ( P < 0.05). Performance was significantly improved by both levels of QY at 21 and 42 d, and significant linear effects were observed for these variables ( P < 0.05). All carcass characteristics were significantly improved by QY administration and significant linear responses were observed for each carcass variable ( P < 0.05). These results indicate that by reducing intestinal disease challenge, QY provided linear improvements in performance. In addition, QY positively affected carcass parameters as each variable responded linearly to QY feeding ( P < 0.05).
