“…Therefore, increased duodenal villus height and the ratio of the villus height to crypt depth in the broilers fed ELBG diet could improve their nutrients digestibilities in this study. Similar result was observed in broiler chicks fed diet with GMOS by Rajani et al (2016). Brufau et al (2015) found in a study of infected Salmonella chickens that the 0.1% galactomannan-rich diet group had longer fluff lengths than the negative control group (Salmonella infection) and the antibiotic group, indicating half Lactomannan has the ability to increase the surface area of the epithelium.…”

To investigate the effects of different levels of enzymatic hydrolysate of dietary locust bean gum on nutrient digestibility, intestinal morphology and microflora of broilers, a total of 768 one-day-old Arbor Acres (AA) broiler chicks were randomly divided into 6 treatments with 8 replicates per treatment and 16 birds per replicate.The treatments were as follows: (1) CON, basal diet; (2) ANT, basal diet +62.5 mg/kg flavomycin; (3) LBG, basal diet +0.1% locust bean gum; (4) ELBG-0.1, basal diet +0.1% enzymatic hydrolysate of LBG; (5) ELBG-0.2, basal diet +0.2% enzymatic hydrolysate of LBG; and (6) ELBG-0.3, basal diet +0.3% enzymatic hydrolysate of LBG. The digestibilities of ether extract, crude protein and dry matter were increased (p < .01) in broilers fed the ELBG-0.3 diet compared with the CON and LBG diets on day 21.Duodenal villus height and the ratio of the villus height to crypt depth were greater (p < .01) in broilers fed the ELBG-0.3 diet than the CON, ANT and LBG diets. Jejunum villus height was higher (p < .05) in broilers fed the ELBG-0.2 and ELBG-0.3 diets than the CON diet. The number of caecal Escherichia coli was reduced (p = .01) in broilers fed the ELBG-0.2 and ELBG-0.3 diets compared with the CON diet. The number of caecal Lactobacilli was greater (p < .05) in broilers fed the ELBG-0.3 diet than the CON and ANT diets. In summary, the addition of 0.3% locust bean enzymatic hydrolysate can increase the surface area of intestinal villi and the number of beneficial bacteria, inhibit the proliferation of harmful bacteria, maintain the balance of intestinal microflora and improve the digestibility of nutrients.

“…In our study, we were able to observe a significant increase in the duodenum villi height of the treated group in most samplings, as previously described in healthy broilers [ 15 ]. A similar increase in villus height in the jejunum of broilers given supplements of probiotics or prebiotics and challenged with S. Typhimurium has been reported [ 2 , 6 , 32 , 40 , 42 , 44 , 45 ]. Fermented soybean, butyric acid, sodium butyrate, oligosaccharides, zinc, and dietary clay supplementation in S. Typhimurium-challenged broilers resulted in an increase in villi height in the small intestine, mitigating Salmonella spp.…”

“…Many authors have reported shortening of villi after a Salmonella spp. challenge [ 2 , 6 , 7 , 29 , 35 , 39 , 40 , 41 , 42 , 43 ], which implies difficulty in absorption capacity and a reduction in body weight gain [ 29 , 40 , 41 , 44 ]. In our study, we were able to observe a significant increase in the duodenum villi height of the treated group in most samplings, as previously described in healthy broilers [ 15 ].…”

Salmonella spp. contaminates egg and poultry meat leading to foodborne infections in humans. The emergence of antimicrobial-resistant strains has limited the use of antimicrobials. We aimed to determine the effects of the food supplement, fermented defatted ‘alperujo’ (FDA), a modified olive oil by-product, on Salmonella Typhimurium colonisation in broilers. One hundred and twenty 1-day-old broilers were divided into four experimental groups—two control groups and two treated groups, and challenged with S. Typhimurium at day 7 or 21. On days 7, 14, 21, 28, 35, and 42 of life, duodenum and cecum tissue samples were collected for histopathological and histomorphometric studies. Additionally, cecum content was collected for Salmonella spp. detection by culture and qPCR, and for metagenomic analysis. Our results showed a significant reduction of Salmonella spp. in the cecum of 42-day-old broilers, suggesting that fermented defatted ‘alperujo’ limits Salmonella Typhimurium colonization in that cecum and may contribute to diminishing the risk of carcass contamination at the time of slaughter. The improvement of the mucosal integrity, observed histologically and morphometrically, may contribute to enhancing intestinal health and to limiting Salmonella spp. colonisation in the host, mitigating production losses. These results could provide evidence that FDA would contribute to prophylactic and therapeutic measures to reduce salmonellosis prevalence in poultry farms.

“…Chicken intestine is continuously exposed to pathogenic bacteria via contaminated feed and water. Salmonella Typhimurium (ST), a major serotype of Salmonella, can infect broiler chickens, leading to decrease in their growth and food-borne diseases in humans (Rajani, et al, 2016). ST infects intestinal cells and macrophages in the small and large intestinal mucosa.…”

Lactobacillus reuteri Enhances the Mucosal Barrier Function against Heat-killed Salmonella Typhimurium in the Intestine of Broiler Chicks

et al. 2020

Salmonella Typhimurium (ST) infection in chickens inhibits their growth and can lead to food-borne diseases in humans. Probiotics are expected to enhance the function of host intestinal barrier against pathogen infection. The aim of our study was to determine the effect of viable Lactobacillus reuteri (LR) on the response of the mucosal barrier function to antigen stimulation in broiler chicks. Day-old male (n＝8) and female (n＝4) broiler chicks were orally administered either 1×10 8 LR or a water-only control, every day for 7 days. After 7 days, either 1×10 8 heatkilled ST (k-ST), or a buffer-only control, was administered via intra-cardiac injection. The ileum and cecum were collected 3 h post-injection, and paraffin sections were prepared for either mRNA extraction (males), or gut permeability tests (females). Villus and crypt lengths were determined via histological analysis. Real-time PCR was used to calculate expression levels of Toll-like receptors (TLRs), pro-inflammatory cytokines, anti-inflammatory cytokines, avian β-defensins, and tight-junction-associated molecules. Gut permeability was assessed using the inverted intestine method. We found that (1) expression of TLR2-1, TLR21, TGF-β2 and TGF-β3 were reduced following k-ST stimulation, but were unaffected by LR-treatment; (2) oral administration of LR led to increased Claudin1, Claudin5, ZO2, and JAM2 expression following k-ST stimulation; (3) cecal permeability was reduced by co-treatment with LR and k-ST, but not by treatment with LR or k-ST alone. These results suggest that LR, as used in this study, may enhance the intestinal mucosal physical barrier function, but not the expression of other immunerelated factors in newly hatched chicks.
