“…The PEG can form complexes with tannins. Thus, there is not enough free tannin to influence the mechanisms responsible for the absorption of nutrients at cellular level (Mansoori et al, 2007b;Mansoori & Modirsanei, 2012). As stated earlier, the digestion of dietary nutrients is affected adversely by tannins (Jansman, 1993), causing impaired performance.…”

“…Dei et al (2008) stated that broilers fed diet containing shea nut meal (a high-tannin feed ingredient) had lower performance than those fed the control diet. Ebrahim et al (2015) (Jansman, 1993;Longstaff & McNab,1991), reduction in mineral and vitamin availability (Jansman, 1993), alteration in metabolic pathway (Mansoori et al, 2007b;Mansoori & Modirsanei, 2012), increase in the endogenous losses of protein and amino acids, particularly methionine, histidine and lysine (Mansoori & Acamovic, 2007), and deleterious effects on internal organs such as the intestines, liver and pancreas (Ortiz et al, 1994). When one considers these adverse consequences, the growth-depressing effect of OA is not surprising.…”

“…Supplementation with tannin-biding agents such as PEG is one of these strategies (Medugu et al, 2012). PEG can form complexes with tannins, thereby preventing the binding of tannins with dietary nutrients (Mansoori et al, 2007b). The beneficial effects of PEG in reducing the negative effects of tannins in ruminants have been indicated (Mlambo et al, 2015).…”

“…Conversely, Karunajeewa et al (1990) did not find significant interactions between various dietary levels of rapeseed meal (a feedstuff with 20-30 g/kg tannins) and PEG in broilers. Various authors have reported beneficial effects of PEG in reducing the adverse consequences of tannic acid (TA) on performance (Mansoori et al, 2007a) and intestinal absorption of D-xylose in broilers (Mansoori et al, 2007b, Mansoori & Modirsanei, 2012.…”

This study was conducted to investigate the potential for replacing corn with oak acorn (OA), a tanninrich feedstuff, and the possible role of polyethylene glycol (PEG) in reducing detrimental effects of OA on broilers. A 3 × 2 factorial arrangement of treatments was used with three levels of OA (0, 150, and 200 g/kg diet), with and without 10 g/kg PEG. A total of 528 one-day-old male and female Cobb 500 broiler chicks were randomly assigned to one of six experimental treatments, with four replicates of 22 birds each. OA was included in the starter (days 1-21) and finisher (days 22-42) diets as a replacement for corn, without changing the dietary levels of other ingredients. The results indicated that dietary inclusion of OA, without PEG, significantly reduced bodyweight gain (BWG) overall (days 1-42) and resulted in worse finisher and overall feed conversion ratios (FCR). PEG had no significant effect on the performance of birds fed diets without OA, but improved overall the BWG of birds receiving 150 and 200 g/kg OA as well as finisher and overall the FCR of birds given 150 g/kg OA. Liver and pancreas weights were not significantly influenced by OA level, PEG or their interaction. Feeding with 200 g/kg OA had deleterious effects on some tibia traits. In conclusion, a significant interaction between OA level and PEG indicates that PEG has the potential to reduce the adverse effects of OA, leading to improved performance. Thus, up to 150 g/kg OA could be included in PEG-supplemented diets, without adverse effects on performance or the tibia traits of broilers. ______________________________________________________________________________________

“…Lack of higher SFP effect on performance may be due to its tannic acid content. Tannins not only reduce the digestibility of dietary ingredients through the formation of complexes with the substrates or their related enzymes, but also disturb the transport mechanisms involved in absorption of simple molecules (Mansoori et al, 2007). As a conse- Table 2.…”

The effects of different levels of 0.0 sumac fruit powder (Z-SFP), 0.25 (L-SFP), 0.50 (M-SFP) and 1% (H-SFP) along with 100 mg/kg alpha tocopherol acetate (VE) were investigated on performance and blood antioxidant status of broiler chickens under heat stress condition. L-SFP, M-SFP and VE birds showed higher body weight gain (BWG) than Z-SFP and H-SFP birds during the starter period (P<0.05). No significant differences were observed among the treatments for feed intake (FI) during the starter, grower and whole the experimental periods (P>0.05). Feed conversion ratio (FCR) of M-SFP and VE birds were lower than that of H-SFP birds during the starter period (P<0.05). Moreover, no significant differences were observed for FCR or BWG between the treatments during the grower and whole the experimental periods (P>0.05). The blood total antioxidant capacity (TAC), malondialdehyde (MDA) content and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GPX) enzymes were not affected by dietary treatments at week 6 of age (P>0.05). It was concluded that although dietary SFP consumption can improve the performance of broiler chickens during the starter period under heat stress, it does not affect the performance during grower period or the blood antioxidant indices at week 6 of age.
