“…We assume that in our experiment, the probable mechanism of action is inhibition of deamination and methanogenesis, leading to decrease in the concentration of methane and acetate, and increase in the concentration of propionate and butyrate [10] (as a result of the addition of elecampane at a dose of 3.0 g/kg DM and wormwood in dose of 10.0 g/kg DM). Our findings are in part consistent with those reported in other sources [13,14]. It has been shown that low doses of biologically active plant compounds increase the concentration of butyric acid [6]; herein, this was observed at low doses of Inulae rhizomata et radices.…”

“…In in vitro study, the effect of phytobiotics and their components on the VFA profile was observed, but it was noted that they did not affect the nitrogen concentration in the ruminal fluid [14,15]. These authors suggested that herbal concentrations shall be higher than 35 mg/l in order to induce any significant changes in rumen nitrogen metabolism.…”

Changes in the concentration of methane in the ecosystem in vitro against the background of Asteraceae family plants biomass

The assessment of Asteráceae Family Plants (rhizomes and roots of elecampane and wormwood) influence on the process of methane formation in the rumen ecosystem and metabolic processes was carried out. Studies (in vitro) were carried out using ANKOM Daisy II incubator (modifications D200 and D200I) according to a specialized method. Rumen contents were obtained from beef bulls with chronic rumen fistula. Gas analysis of air and volatile fatty acids samples was performed by gas chromatography. The results of the study showed that different dosages of phytobiotic preparations did not significantly affect the characteristics of fermentation in vitro. Phytobiotic preparations of elecampane and wormwood reduce the production of methane in the ruminal fluid, which may be associated with various active components or dosages of their administration.

“…There were 17 replicate cages per treatment and 16 birds per cage. The experimental period was 35 days, including starter period (days 0-7), grower period (days 7-21), and finisher period (days [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. The dietary treatments used included: 1) basal diet (no additive, control group), 2) basal diet including 0.2 g/kg of QS, 3) basal diet including 0.4 g/kg QS, and 4) basal diet including 0.6 g/kg QS.…”

Objective: The objective of this study was to evaluate the effects of supplementing quercetin extracted from Sophora japonica flower (QS) to the diet of broiler chicks on their growth performance, apparent nutrient digestibility, cecal microbiota, serum lipid profiles, relative organ weight, and breast muscle quality.Method: A total of 1088 1-day-old broiler chicks (mixed sex) were randomly assigned to four groups based on the initial body weight (43.00 ± 0.29 g). The experimental period was 35 days (starter, days 0-7; grower, days 7-21; finisher, days 21-35). There were 17 replicate cages per treatment and 16 birds per cage.Dietary treatments consisted of birds receiving basal diet without quercetin as the control group and treatment groups consisted of birds fed basal diet supplemented with 0.2, 0.4, or 0.6 g/kg QS.Results: With the increase of the QS dosage, body weight gain during days 0-7 (P = 0.021), 7-21 (P = 0.010), and 1-35 (P = 0.045), feed intake during days 0-7 (P = 0.037) and 1-35 (P = 0.025), apparent dry matter digestibility (P = 0.008), apparent energy retention (P = 0.004), cecal lactic acid bacteria counts (P = 0.023), the relative weight of breast muscle (P = 0.014), pH value from breast muscle (P < 0.001), and the water holding capacity of breast muscle (P = 0.012) increased linearly, whereas the drip loss from breast muscle (P = 0.001) decreased linearly. Conclusion:The addition of QS in the diet of broiler chicks had positive effects on the breast muscle yield and breast muscle quality, and improved the dry matter digestibility and energy retention by increasing cecal beneficial bacteria counts, thus improving growth performance.

“…This is supported by the increase in the VH:CD ratio in the duodenum, jejunum, and ileum. The ratio itself is a histological index for intestinal digestive capacity; a higher value indicates that the chicken has better intestinal health and higher absorption capacity [16]. Therefore, promotion of performance results due to addition of flavonoids is inseparable from the high ratio of villi length and CD.…”

Effects of dietary flavonoids on performance, blood constituents, carcass composition and small intestinal morphology of broilers: a meta-analysis

et al. 2021

Objective: This study aims to evaluate the influence of dietary flavonoids on the growth performance, blood and intestinal profiles, and carcass characteristics of broilers by employing a meta-analysis method.Methods: A database was built from published studies which have reported on the addition of various levels of flavonoids from herbs into broiler diets and then monitored growth performance, blood constituents, carcass proportion and small intestinal morphology. A total of 42 articles were integrated into the database. Several forms of flavonoids in herbs were applied in the form of unextracted and crude extracts. The database compiled was statistically analyzed using mixed model methodology. Different studies were considered as random effects, and the doses of flavonoids were treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was <0.05.Results: Dietary flavonoids increased (quadratic pattern; p<0.05) the average daily gain of broilers in the finisher phase. There was a reduction (p<0.01) in the feed conversion ratio of the broilers both in the starter (linear pattern) and finisher phases (quadratic pattern). The mortality rate tended to decrease linearly (p<0.1) with the addition of flavonoids, while the carcass parameter was generally not influenced. A reduction (p<0.001) in cholesterol and malondialdehyde concentrations (both linearly) was observed, while super oxide dismutase activity increased linearly (p<0.001). Increasing the dose of flavonoids increased (p<0.01) the villus height (VH) and villus height and crypt depth (VH:CD) ratio (p<0.05) in the duodenum. Similarly, the VH:CD ratio was elevated (p<0.001) in the jejunum following flavonoid supplementation.Conclusion: Increasing levels of flavonoids in broilers diet leads to an improvement in growth performance, blood constituents, carcass composition and small intestinal morphology.
