“…Tissues were immediately placed in 4 % buffered formalin solution for 24 h after which the solution was replaced with distilled water until further analysis. Tissue was processed for hematoxylin-eosin staining as was described by Buyse et al (8). Tunica muscularis width (TM), villus length, villus width, crypt depth and crypt width were randomly measured in 10 villi per section using a light microscope (Leica DM LB2 Digital, Leica Microsystems, Wetzlar, Germany) and a computer-based image analysis program (Leica Application Suite V4.1, Leica microsystems, Wetzlar, Germany).…”

“…Tannins cause protein to precipitate, and microelements to be chelated, making them unavailable for the animal (1). Nevertheless, in limited dosages, beneficial traits could be attributed to these additives (2)(3)(4)(5)(6)(7)(8).…”

“…These have excellent antioxidative properties and have been proven to be beneficial to overall health in chickens (6,11,12). Indeed, higher doses of chestnut tannins, i.e., more than 0.2%, have been reported to be unfavorable to animal performance due to increased feed conversion ratio, although few effects have been reported on digestibility coefficients (2,8,13). This suggests that other mechanisms than impaired digestibility are responsible for the lower performance in growing broiler chickens receiving high doses of chestnut tannins.…”

It is known that high doses of various tannins could impair broiler growth, and this seems to be linked to a lowered protein availability. However, e ects on protein digestion under the influence of hydrolysable tannins were minimal in previous research and literature. Other possible proposed reasons to explain reduced growth are scarce. In this experiment we studied the e ect of hydrolysable tannins on body allometry by using di erent feeding schemes throughout the rearing period. In total individually reared male Ross broilers received a -phase basal diet with chestnut wood extract (+: , mg/kg) or not (-: mg/kg) (Tanno-SAN ® , Sanluc International NV, Belgium).This resulted in groups during the starter period (S+, S-), groups in the grower period (G++, G+−, G-+, G-) and groups in the finisher periodSimilar to previous studies, growth reduction was also observed in this study. E ects were the largest in broilers that were given the tannins during the grower phase. At the end of each phase broilers per group were euthanized and sampled. Liver, pancreas, pectoralis muscle, intestinal weights and intestinal length were recorded. The largest e ects were seen on the intestine. Broilers that received tannins during the grower phase, had longer intestines at the end of the finisher period. Furthermore, histological di erences between treatment groups were observed at the end of the grower period. Addition of tannins in the grower phase (G-+, G++) resulted in longer villi, whereas addition of tannins in the starter (G+−, G++) caused deeper crypts at the end of the grower phase, with the group (G-+) having the highest villi-to-crypt ratio. These results tentatively prove that tannins influence intestinal growth, both macroscopically as well as histologically. We hypothesize that the observed growth reduction with tannins could be the result of a changed energy and nutrient partitioning, i.e., more nutrients are directed to intestinal growth than for muscle growth.

“…Although the flaxseed flour has been processed, it still contains the antinutrient because microwave processing is unable to deactivate all the antinutrient content. The antinutrient factors can inhibit the activity of the amylase enzyme by binding to the feed nutrients, so that the availability of the substrate is reduced (Buyse et al 2021).…”

This research aimed to evaluate the effect of the use of microwaved flaxseed flour as broiler feed on the growth performance and digestive enzyme activity. The material used was 200 a-day-old chicks strain Lohmann MB Platinum. The method of this research was in vivo feeding trial using a Completely Randomized Design (CRD) with 5 treatments and 4 replications. The treatments included the use of flaxseed flour with levels of 0% (T0), 2.5% (T1), 5% (T2), 7.5% (T3), and 10% (T4). The variables measured were feed intake, body weight gain, feed conversion ratio, mortality, amylase, and protease activity. The data obtained were analyzed by Analysis of Variance (ANOVA) and Duncan’s Multiple Range Test (DMRT). The result showed that the treatments highly significant (p<0.01) increasing the amylase activity and decreasing the protease activity, but had no significant effect on the feed intake, body weight gain, feed conversion ratio, and mortality. It can be concluded that the use of microwaved flaxseed flour up to 10% did not give negative effect on broiler, but 2.5% showed the best result compared to other treatments. Key words: broiler, digestive enzyme activity, flaxseed flour, growth performance, microwave
