“…Also in the current study, pancreas weight was not affected by OA, which is in line with other studies (Longstuff & Mc Nab, 1991;Nyacotti et al, 1996). Conversely, in some previous studies (Ahmed et al, 1991;Mahmood et al, 2008), pancreatic hypertrophy was observed in broilers given high-tannin diets. Because pancreatic enzymes are inhibited by tannins, their production would be increased by the pancreas.…”

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. ______________________________________________________________________________________

“…On the other hand supplementation of oak tannin decreased the feed intake. This result is consistent with findings of Ibrahim et al (1988), Nyachoti et al (1997), Trevino et al (1992), Vilarino et al (2009), Mahmood et al (2008.…”

“…As can be seen from Table2 quails fed with diets including oak tannin had considerably low FiBW. These results are in agreement with findings of Ibrahim et al, 1988;Nyachoti et al, 1997;Trevino et al, 1992;Vilarino et al, 2009;Mahmood et al, 2008. As can be seen from Table 2, BWG, FI ranged from 99.48 to 168.90 and 516.75 to 680.08 g with the highest BWG and FI for quails fed with control diet. BWG and FI decreased with increasing dose of oak supplementation whereas FCR increased with increased oak supplementation.…”

In the present study effects of different levels of hydrolyzed oak tannin on Japanese quail, live body weight and live body weight gain, food intake, food conversion efficiency and mortality rate were investigated. Therefore, a total of 240 quails were weighed and divided into 4 treatment groups each with 3 replicates containing 20 birds and reared in flat for 42 days as experimental period. While one of the groups was fed control diet with no additives (0% tannin A), other groups were fed with the different percentages of tannin on their diets, which are 0.5% (B), 1.0% (C), 1.5% (D) respectively. It has been observed that Japanese quails that fed the oak tannin containing diet had slower growth rate and poorer feed conversion efficiency and high mortality rate than birds fed with a tannin-free diet.

“…Proventriculus extract only was used for assaying pepsin activity (EC 3.4.23.1) while three intestinal extracts were used to assay the activities of trypsin (EC 3.4.21.4), chymotrypsin (EC 3.4.21.1), αamylase (EC 3.2.1.1), cellulase (EC 3.1.1.4) and lipase (EC 3.1.1.3). All analyses were conducted at 37°C with a preferred pH as described in previous reports (Gabriel, Mallet, & Leconte, 2003;Ghalehkandi et al, 2011;Jang, Ko, Kang, & Lee, 2007;Mahmood, Khan, Sarwar, & Nisa, 2008;Shin, Han, Ji, Kim, & Lee, 2008). The pepsin activity was assayed using casein as a substrate, according to the method of Rungruangsak and Utne (1981).…”

A feeding trial was conducted to determine the effect of organic acids or probiotics alone or in combination on growth performance, nutrient digestibility, enzyme activity, intestinal morphology and gut microflora in broiler chickens (Ross308). A completely randomized design was used, with 1,440 broiler chicks across four treatments and five replications of 72 chicks each. The chicks in the control treatment were fed on a control diet (CD), whereas for the other treatment groups, the CD was supplemented with 0.2 g/kg organic acids (CDOA), probiotics (CDP) or a combination of organic acids and probiotics (CDOAP). All the chicks were fed ad libitum during the feeding trial throughout 35 days. A total of 20 chicks were randomly allotted to individual metabolic cages to measure the nutrient digestibility (35-42 days) and the digestive enzyme activities (42 days). The intestinal morphology and gut microflora of 80 chicks were examined at the end of experiment. There were no significant (p > .05) differences in the feed intake, body weight gain or feed conversion ratio of the chicks across the four dietary treatments. The crude fibre digestibility was significantly increased in chicks fed on CDOA or CDOAP relative to CD (p < .05). Nutrient utilization, in terms of digestive enzyme activities and excreta thermal property, was unchanged by any supplementation. The chicks fed on the CDOAP had significantly higher duodenal villi height and crypt depth than the chicks fed on CDOA (p < .05). This dietary treatment dramatically improved gut microflora by decreasing the population of Escherichia coli and increasing the Lactobacillus spp.:E. coli ratio. Based on our investigations, supplementation of organic acids and probiotics in chick diets can increase the ability to digest crude fibre and villus height and decrease intestinal E. coli without impairing growth performance.
