“…As a result of phytochemical testing (1.2.2.1), a ferric chloride chemical test successfully revealed intense tannin presence in the extracts. [31] Furthermore, the HCl and NaOH testing indicated saponins and flavonoids presence, respectively. (Figure 4) The former did not present a significant color change which indicates the low saponin concentration.…”

In the present work, green synthesis is utilized in the synthesis of silver nanoparticles with hazelnut (Corylus Colurna) husk which is the outer leaf part of the hazelnut shell and is considered bio‐waste. According to transmission electron microscopy and x‐ray diffraction analysis, the morphology of the silver nanoparticles synthesized by 0.1 g/mL hazelnut husk extract is found to be spherical with an average diameter of 6.57 nm and possesses ultra‐narrow size distribution. UV‐visible spectrometry reveals the absorbance peak range between 450–475 nm which is in the range of surface plasmon resonance peak of silver nanoparticles with spherical morphology. Antibacterial properties of the synthesized silver nanoparticles were tested on E. coli and significant antimicrobial activity was found with up to 79 % areal inhibition efficiency. The research revealed that the hazelnut husk extract, a reducing agent used in syntheses with different mass concentrations of hazelnut husk extract, also affects the size of the nanoparticles, allowing for the possibility of controlling their size. The antibacterial properties of silver nanoparticles, synthesized in a spherical form of different sizes, correspondingly increased their effect on bacteria which is observed in the inhibition zone. The synthesis of silver nanoparticles, which can be used in many fields for agriculture, cosmetics, and medical purposes, using plant extract and minimal chemicals is crucial because it affects its toxicity. The synthesis of silver nanoparticles with hazelnut husk not only reduces the chemical waste and toxicity, but it is both easily accessible and helps the environment and sustainability by recycling a normally considered bio‐waste by‐product of high‐value‐added crop to a technologically valuable product silver. Moreover, synthesized silver nanoparticles could be an essential part of applications ranging from antibacterial surface treatments to drug delivery systems.

“…Studies have shown that adding polyethylene glycol to diets containing tannins increases the protozoa population and ruminal ammonia nitrogen concentration (Abarghuei et al., 2010 ). In another study, the concentration of ammonia nitrogen in cows fed silage of pistachio by‐products decreased compared to the control and supplementation of silage of pistachio by‐products with urea (tannin binder) increased ammonia nitrogen (Mokhtarpour et al., 2012 ). Use of tannin sources such as grape pomace in sheep diet (Abarghuei et al., 2010 ), PP extract in the diet of lactating cows (Abarghuei et al., 2013 ), and various tannin sources in the diet of beef cattle (Orzuna‐Orzuna et al., 2021 ) decreased ammonia nitrogen concentration and ruminal protozoa population but did not affect ruminal pH.…”

“…The difference in the results can be due to the climatic conditions of the area of the growth of pomegranate and harvest time (Ben Salem et al., 2005; Brooker & Kleinig, 2006; Taher‐Maddah et al., 2012). In a study by adding polyethylene glycol or urea to pistachio by‐products (Mokhtarpour et al., 2012), the percentage of CP decreased from 12.28 to 12.02, ADF from 26.33 to 26.01, DM from 32.53 to 23.70; and NDF increased from 36.45 to 36.48.…”

BackgroundThe use of plants and by‐products, which are containing a high amount of secondary and anti‐nutritional compounds such as tannins, in animal feed is limited. The methods that can reduce these compounds make facilitate their use in animal feed.ObjectivesThe aim of this study was to reduce the adverse effects of pomegranate peel (PP) tannin for fattening lambs using the tannase‐producing bacteria.MethodsTwenty‐one Arabi male lambs (averagely 35 ± 3.8 kg weight and 8 ± 1.0 months age) were used in a completely randomized design with three treatments and seven replications in the present experiment. The experimental treatments included 1 – control diet (CNT, no PP), 2 – diet containing untreated PP (raw PP, UTPP) and 3 – diet containing PP treated with tannase‐producing bacteria (bacteria treating PP, BTPP).ResultsUsing UTPP decreased nutrient intake compared to the control and treatment with tannase‐producing bacteria again significantly increased nutrient intake compared to the UTPP (p < 0.05). The digestibilities of organic matter, neutral detergent fibre and acid detergent fibre in the control treatment were significantly higher than UTPP and BTPP and in the BTPP were significantly higher than the UTPP (p < 0.05). The use of UTPP in the diet significantly decreased the pH, ammonia nitrogen concentration and the total protozoa population of the rumen compared to the control (p < 0.05), and treatment with bacteria increased them again. The lowest total protozoa population was observed in UTPP treatments (p < 0.05). The highest concentration of blood glucose was observed in UTPP; however, the highest concentrations of blood urea nitrogen, cholesterol, triglyceride, high‐density lipoprotein (non‐significant) and low‐density lipoprotein were in the control treatment. The effect of experimental treatments on the dry matter consumption of the whole period was significant; however, there was no significant effect on average daily gain, feed conversion ratio, feed efficiency and longissimus muscle colorimetric systems.ConclusionsTherefore, considering the positive effects of treatment PP with tannin‐degrading bacteria relative to raw PP, using these bacteria is a proper way to reduce tannin, thus improving the nutritional value of PP for ruminants.
