Influence of Anti-Coccidial Compounds and Phytogenic Saponin Extracts on In Vitro and In Vivo Ruminal Fermentation and Methane Production of Cattle.

Four experiments were conducted to evaluate sources of anti-coccidial compounds and phytogenic saponin extracts on in vitro and in vivo ruminal fermentation and CH4 production at multiple inclusion levels. In experiment 1, eight steers were fed either a finishing diet or a finishing diet supplemented with 0.5 mg/kg BW decoquinate (DCQ) and 3.33 mg/kg BW Yucca schidigera extract (YSE), and respiratory gas exchange was measured. In experiment 2, four ruminally-cannulated steers were fed the same treatments as experiment 1, and ruminal fermentation was evaluated. Anti-coccidial sources (experiment 3; monensin, DCQ, amprolium) and saponin sources (experiment 4; YSE, Quillaja saponaria extract) and levels were evaluated for effects on in vitro ruminal fermentation and CH4 production. DCQ + YSE supplementation did not influence (p ≥ 0.24) in vivo respiratory gas consumption/production, in situ DM degradation, or liquid passage kinetics. Ruminal propionate proportion tended to increase (p = 0.09) with DCQ + YSE. Monensin decreased (p ≤ 0.04) in vitro acetate:propionate and CH4 production; saponin supplementation linearly increased (p < 0.01) propionate proportion but did not influence (p ≥ 0.38) in vitro CH4 production. Saponins and non-antibiotic anti-coccidials did not influence in vitro or in vivo CH4 production with finishing diets.

Yucca schidigera extract decreases nitrogen emission via improving nutrient utilisation and gut barrier function in weaned piglets.

Yucca schidigera extract (YE) can decrease ammonia concentration in livestock housing, which could be associated with the inhibition of urease. The aim of this study was to investigate the other possible reasons of dietary YE supplementation reducing nitrogen emission in weaned piglets. A total of 14 crossbred weaned barrows were allotted into two groups fed the diets supplementing 0 and 120 mg/kg YE for 14 days. The YE administration decreased F/G ratio and hindgut NH3 -N production in weaned piglets (p < 0.05). Dietary YE supplementation decreased serum urea nitrogen levels, and increased nutrient digestibility, which could be related to the improvement of morphology, digestive and absorptive enzyme activities, and nutrient transporter mRNA expression in jejunal mucosa of weaned piglets (p < 0.05). The mRNA expression of tight junction proteins, mucins and apoptosis-related genes was also improved by YE treatment in jejunal mucosa of weaned piglets (p < 0.05). In addition, dietary YE supplementation regulated the microbiota structure and volatile fatty acid content in distal intestine of weaned piglets (p < 0.05). These results suggest that YE administration can decrease hindgut NH3 -N production in weaned piglets, which is associated with the increased nutrient utilization and gut-barrier function.

Dietary Yucca schidigera Extract Supplementation During Late Gestating and Lactating Sows Improves Animal Performance, Nutrient Digestibility, and Manure Ammonia Emission.

This study was conducted to investigate the effect of dietary Yucca schidigera extract (YSE) supplementation to sow performance, nutrients digestibility and ammonia emission of manure. Total 80 sows were randomly divided into 4 groups and fed with either control, control + 0.06% YSE, control + 0.12% YSE or control + 0.24% YSE diet from day 80 of gestation to day 21 of lactation. The results showed that dietary YSE supplementation resulted in trends toward a reduced number of stillbirth piglets (P = 0.08), weak piglets (P = 0.06), pre-weanling mortality (P = 0.04) and diarrhea (P = 0.03), and improved apparent digestibility of dry matter (P = 0.04). Besides, YSE supplementation significantly increased catalase activity (P = 0.02) while decreasing malonaldehyde levels (P = 0.04) in sow blood. Furthermore, the loss of total nitrogen, urea nitrogen and ammonia nitrogen in sow manure were significantly reduced with supplementation of YSE. In summary, supplementation of YSE in sow diet during late gestation and lactation could improve sow and litter performance, nutrient digestibility, and reduce nitrogen loss in sow manure during storage.

THE POTENTIAL EFFICACY OF ALOE VERA GEL AND YUCCA SCHIDIGERAEXTRACT ON GROWTH PERFORMANCE, INTESTINAL LESIONS AND INFLAMMATORY RESPONSE IN BROILER CHICKENS CHALLENGED WITH COCCIDIA

ABSTRACT This study was conducted to investigate the effect of Aloe veragel and Yucca schidigeraextract supplementation on growth performance,oocyst shedding,intestinal lesions and inflammatory response in broilers challenged with coccidia. Two hundred and ten, one-day old Cobb chicks were randomly allocated to seven equal groups (30 birds/group).(G1): non-infected non-treated group, (G2): infected non-treated group,(G3)&(G4): infected and treated with Aloeveragel 5gm/L and Yucca schidigeraextract 200 mg/ L respectively from 7th day of age till the end of the experiment, (G5)&(G6): infected and treated with Aloe veragel 5gm/L andYucca schidigeraextract 200 mg/L respectively from 15th day of age till the end of the experiment and (G7): infected and treated with Amprolium 1g/ 2 L from 15th day for five successive days.Chickens in infected groups were challenged with 50,000sporulatedoocysts of field strain of Eimeria spp. on the 14th days of age. The average body weight gains, feed intake and feed conversion ratio were recorded all over the experimental period. The anticoccidial evaluation post infection depended on severity of bloody diarrhea, lesion scores as well as the oocyst shedding. In addition, histopathological changes in intestine and serum level of inflammatory cytokines were evaluated. Aloe veragel and Yucca schidigeraextract supplementation were able to mitigate the devastating effects of coccidia challenge in broilers.Growth performances represented by bodyweight gain, and feed conversion ratio were significantly improved.The Lesion score and oocysts shedding were significantly reduced as well as the serum level of pro-inflammatory (IL-6 and IL-1β) were significantly down regulated in challenged treated groups. The histopathological changes of intestine were ameliorated in treated supplemented groups. In conclusion, Aloe verageland Yucca schidigeraextract can be a promising candidate to be used as a natural, low cost alternative to control coccidiosis in chickens.

Effect of probiotics and Yucca schidigera extract supplementation on broiler meat quality

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p &lt; 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p &gt; 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p &lt; 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p &lt; 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p &lt; 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.

Dietary supplementation of Yucca schidigera extract enhances productive and reproductive performances, blood profile, immune function, and antioxidant status in laying Japanese quails exposed to lead in the diet

The present study investigated the toxic impacts of lead (LD) on the productive and reproductive performances of Japanese quails and the role of Yucca schidigera extract (YSE) in reducing these impacts. A total of 360 mature Japanese quails (at 2 months of age) were used and the experiment was lasted for 8 wk. The birds were divided into 6 equal groups as follows: control (basal diet), basal diet + 100mg LD/kg diet, basal diet + YSE (100mg/kg diet), basal diet + YSE (200mg/kg diet), basal diet + LD (100mg/kg diet) + YSE (100mg/kg diet), and basal diet + LD (100mg/kg diet) + YSE (200mg/kg diet). LD resulted in a significant decrease in feed intake (FI), feed conversion ratio (FCR), and egg production of birds compared with the control group. Supplementation of YSE (100 or 200) to LD containing diet could significantly improve the quail performance parameters to be comparable with the control values. Fertility and hatchability % were decreased by LD, whereas YSE at both levels (100 or 200) separately or in combination with LD showed fertility and hatchability percentages comparable to that of control. Triglycerides, cholesterol, and LDL contents in LD plus YSE100 or LD plus YSE200 groups were significantly decreased than LD alone group. LD significantly decreased superoxide dismutase and catalase activities in the serum with no effect on reduced glutathione content. Co-exposure to YSE100 or YSE200 with LD significantly increased the catalase activity and numerically increased the superoxide dismutase activity than LD alone. YSE100 or YSE200 decreased malondialdehyde contents than LD alone group. LD plus YSE100 or YSE200 groups exhibited significant improvements in the level of immunoglobulins. Co-exposure to YSE with LD significantly decreased the LD residues in egg than the LD group. The obtained results showed that YSE exhibited a potential modulatory role against the LD-induced inhibitory effects on the productive and reproductive performances of Japanese quails and YSE at 200mg/kg diet was more effective than 100mg/kg diet in reversing the LD-induced alterations.

An in vitro evaluation of the effects of a Yucca schidigera extract and chestnut tannins on composition and metabolic profiles of canine and feline faecal microbiota

ABSTRACTThe in vitro effect of a Yucca schidigera extract (YSE) and tannins from chestnut wood on composition and metabolic activity of canine and feline faecal microbiota was evaluated. Four treatments were carried out: control diet, chestnut tannins (CT), YSE and CT + YSE. The YSE was added to canine and feline faecal cultures at 0.1 g/l, while CT were added at 0.3 g/l for a 24-h incubation. A total of 130 volatile compounds were detected by means of headspace-solid phase microextraction gas-chromatography/mass spectrometry analyses. Several changes in the metabolite profiles of fermentation fluids were found, including a decrease of alcohols (−19%) and esters (−42%) in feline and canine inoculum, respectively, which was due to the antibacterial properties of tannins. In canine inoculum, after 6 h, YSE + CT caused lower cadaverine concentrations (−37%), while ammonia (−4%) and quinolone (−27%) were reduced by addition of CT. After 24 h, the presence of CT resulted in a decrease of sulphur compounds, such as dimethyl sulphide (−69%) and dimethyl disulphide (−20%). In feline faecal cultures, after 6 h, CT lowered the amount of indole (−48%), whereas YSE tended to decrease trimethylamine levels (−16%). Both in canine and feline inoculum, addition of CT and, to a minor extent, YSE affected volatile fatty acids patterns. In canine faecal cultures, CT exerted a marginal inhibitory effect on Escherichia coli population (−0.45 log 10 numbers of DNA copies/ml), while enterococci were increased (+2.06 log 10 numbers of DNA copies/ml) by YSE. The results from the present study show that YSE and tannins from chestnut wood exert different effects on the composition and metabolism of canine and feline faecal microbiota. In particular, the supplementation of YSE and tannins to diets for dogs and cats may be beneficial due to the reduction of the presence of some potentially toxic volatile metabolites in the animals’ intestine.

Effect of Dietary Supplementation of Yucca schidigera Extract on the Performance and Litter Quality of Broilers in Winter Season

The present experiment was designed to study the effect of dietary supplementation of Yucca schidigera extract (YSE) on growth, litter quality, the general health and hygiene in broiler rearing over a six-week period. Day-old broiler chicks (n=120) of equal sex ratio were randomly divided into two dietary groups (YSE and Control); each treatment had three replications of 20 chicks each. The rearing conditions were similar for both the groups, and were as per the standard practices in vogue. Data pertaining to growth of birds, pathogen load of litter and general health and sanitation outlook was recorded. The average BW at 6th week of the experiment was significantly (P<0.05) higher in Yucca group (1995 g) than the control group (1822 g) with lesser feed intake in Yucca group than control group, which ultimately proves better feed conversion rate, protein efficiency ratio, and energy efficiency ratio in broiler production. The Total Bacterial Count was reduced significantly (P<0.05) due to supplementation of YSE. Foot pad and breast blister score was almost nil in both the group. Intensive cake formation of litter in control group was more than that of treatment group. Dietary manipulation with Yucca improved the desirable traits like weight gain and feed efficiency. Litter quality was improved due to better micro-climatic conditions. Hence, it is concluded that Yucca extract could be safely used at a level of 125 mg per kg BW without any adverse effect on growth and health of broilers.

Effects of adding yeast cell walls and Yucca schidigera extract to diets of layer chicks

1. This research was conducted to determine the impact of diet supplementation with yeast cell walls and Yucca schidigera extract on the growth performance, antibody titres, and intestinal tissue histology of layer chicks. 2. White, 1-d-old, Hy-Line hybrid chicks (n = 840) were divided into 4 main groups, each comprising 7 replicates of 30 chicks (n = 210): (1) control; (2) 1000 mg/kg yeast cell walls (YCW) added; (3) 1000 mg/kg Yucca schidigera extract (YE) added; and (4) 500 mg/kg YE + 500 mg/kg YCW added. The trial lasted 60 d. 3. Daily weight gain of the chicks was positively affected between d 45-60 in the YE and YCW + YE groups compared with the control group. 4. Overall, feed consumption did not differ between the control and YCW, YE, YCW + YE groups during the 60 d study period. Feed efficiency was better in the YE and YCW + YE groups than in the control group between d 1-60. 5. During the 60 d evaluation period, live weight gain, and final live weight were higher in YE and YCW + YE groups than in the control group. 6. Antibody titres against infectious bronchitis and infectious bursal disease did not differ among the 4 treatments, but those for Newcastle disease were higher in the YE + YCW groups than in the control, YCW and YE groups on d 45. 7. There were differences in intestinal histomorphometry between the 4 treatments. The height of the jejunal and ileal villi was greater in the YE and YCW + YE groups than in the control and YCW groups 8. It can be concluded that YCW and YE supplementation for layer chicks is beneficial for growth performance and intestinal histology during the 1-60 d growing period.

Effect of Levels of Yucca Schidigera Extract on Ruminal Fermentation Parameters, Digestibility of Nutrients and Growth Performance in Sheep

An in vivo fermentation experiment (Expt.1) and a digestibility and growth trial(Expt.2) were conducted to determine the effect of levels of Yucca Schidigera Extract (YSE) on ruminal fermentation parameters ,digestibility of nutrients and growth performance in Sheep. Three same levels of YSE supplementation were studied in both experiments. In the Expt.1,four rumen fistulated male sheep with initial body weight of 33±1.8 ㎏were randomly assigned according to a 4×4 Latin square design. The dietary treatments were YSE based offering at 0,100, 200 and 300 mg/kg diet. It was found that ruminal pH was not significantly different among treatments. Relative to control, ruminal propionate concentration was increased by YSE addition in a dose-dependent manner by up to 29.79%（P&lt;0.05）,the acetic concentration was decreased by up to2 1.23%（P&lt;0.05）.Ruminal ammonia concentration was larger (P&lt;0.05) in sheep receiving no YSE (increased by 18.86 mg/dl) than in those receiving 200mg/kg (2.85 mg/dl increase in NH3) or 300mg/kg (2.72 mg/dl increase). Protozoa populations in the rumen were lower (P&lt;0.05) with YSE of 200-300 mg/kg than without. In the digestibility and growth trial(Expt.2),increasing levels of YSE resulted in liner increase in daily body weight gain rate (P&lt;0.05) and feed conversion efficiency(P&lt;0.05). Additionally ,apparent digestibilities(%) of DM,OM,CP,and NDF were significantly different in all treatment .In conclusion, the 200 and 300 mg/kg YSE groups have a particular suppressing effect on ruminal ammonia concentration, ammonia N concentrations and protozoa populations were decreased, The effects on ruminal propionate and acetic concentration were probably a result of a selective inhibitory effect of YSE on rumen microbial species. The effect of YSE on ruminal ammonia concentration likely resulted from a decreased population of protozoa, presumably, from ammonia binding by YSE. YSE can significantly improved the apparent digestibility of nutrient and sheep growth performance.

Effect of feeding Yucca schidigera extract on performance of lactating dairy cows and ruminal fermentation parameters in steers

Abstract Two experiments were conducted to determine the effects of Yucca schidigera extract (YE) on firstly, dry matter intake (DMI), milk production and milk composition in lactating Holstein Friesian cows and secondly on DMI and GEI and rumen fermentation parameters of ruminally fistulated Holstein Friesian steers. Three levels of YE supplementation were studied in both experiments. In Experiment 1, 33 early lactating dairy cows that were 69 days in milk (S.D. ± 39) at commencement of the trial were fed YE at either 0, 25 or 50 g/head/day in a randomised block design while in Experiment 2, the three fistulated steers were fed YE at 0, 15 and 28 g/head/day within a latin square design. The lower levels of YE supplementation fed in Experiment 2 were designed to provide similar inclusion rates within the diet as in Experiment 1 after allowing for the higher DMI within Experiment 1. All animals in both trials were offered ad libitum a total mixed ration (TMR) supplemented with concentrates containing the YE. The dairy cows were group housed by diet, however when milk and intake measurements were conducted (days 12 to 18 and days 54 to 60 post commencement of the feeding of the experimental diets) the animals were housed in individual tie up stalls, whereas for Experiment 2 all animals were individually stall fed for the duration of the trial. Feeding YE had no effect on milk yield or composition, however DMI decreased linearly (P

Effect of Yucca schidigera extract on the concentration of rumen microorganisms in sheep

The effects of Yucca schidigera extract (YSE) on pH and the concentration of protozoa, bacteria, and fungi in sheep rumen contents were investigated. In this study, 20 sheep were divided into four groups of five animals each and fed a basal diet for 3 weeks. Each group was then fed an experimental diet containing YSE at levels of 5, 10, 20 and 30 g/head/day, respectively. Samples of whole ruminal contents for measurement of protozoal, bacterial, and fungal concentrations and pH were obtained before feeding by rumenotomy after 3 weeks on the basal diet and by euthanasia after 3 weeks on the experimental diet. Animals fed YSE at a level of 30 g/head/day had higher rumen protozoal concentrations ( P < 0.015) and pH ( P < 0.01) than when fed the basal diet. Except for an increase in pH at the 10 g/head/day level, supplementation of YSE at levels of 5, 10 and 20 g/head/day to the basal diet had no effect on microbial concentrations or pH.
