Fig. 5From: Impact of buffered sodium butyrate as a partial or total dietary alternative to lincomycin on performance, IGF-1 and TLR4 genes expression, serum indices, intestinal histomorphometry, Clostridia, and litter hygiene of broiler chickensInfluence of dietary sodium butyrate and lincomycin on intestinal histomorphometry of broiler chickens (day 35) Photomicrograph of jejunum. H&E. V: intestinal villi, Arrow: intestinal crypt and Lines: intestinal length. A: The control group showing the intestinal villi (V) and intestinal crypts (arrow). B: The Butirex (1 kg) fed group showing significant increase in the intestinal villi length (red lines) compared to control group. C: The Lincomix (100 g) fed group revealing significant increase in the length of villi (red lines) compared to control group. D: The Lincomix (50 g) plus Butirex (0.5 kg then 0.250 kg) fed group showing increase in the length of intestinal villi but not significant compared to groups 1, 2, and 3. E: The Lincomix (50 g) plus Butirex (1 kg then 0.5 kg) fed group exhibiting increase in the length of intestinal villi but not significant compared to groups 1, 2, 3, and 4.
