“…Our study revealed that the inclusion of 10% FBEs im-proved the villus height and villus height/crypt depth ratio, which follows the findings of Peng et al [66,68]. In addition, El-Sanhoury and Ahmed [69] reported increased villus height and numbers after supplementation with exogenous enzymes containing cellulase and xylanase in broiler chickens. An explanation for the improved intestinal villus height and villus height/crypt depth ratio is that cereals containing high levels of NSPs increase the size of the gastrointestinal tract and change the intestinal morphology [70].…”

The present and future high demand of common cereals as corn and wheat encourage the development of feed processing technology that allows for the dietary inclusion of other cereals of low nutritional value in poultry feeding. Barley grains contain anti-nutritional factors that limit their dietary inclusion in the poultry industry. The treatment of barley with solid-state fermentation and exogenous enzymes (FBEs) provides a good alternative to common cereals. In this study, barley grains were subjected to solid-state microbial fermentation using Lactobacillus plantarum, Bacillus subtilis and exogenous fibrolytic enzymes. This study aimed to assess the impact of FBEs on growth, feed utilization efficiency, immune modulation, antioxidant status and the expression of intestinal barrier and nutrient transporter-related genes. One-day-old broiler chicks (Ross 308, n = 400) comprised four representative groups with ten replicates (10 chicks/replicate) and were fed corn-soybean meal basal diets with inclusions of FBEs at 0, 5, 10 and 15% for 38 days. Solid-state fermentation of barley grains with fibrolytic enzymes increased protein content, lowered crude fiber and reduced sugars compared to non-fermented barley gains. In consequence, the group fed FBEs10% had the superior feed utilization efficiency and body weight gain (increased by 4.7%) with higher levels of nutrient metabolizability, pancreatic digestive enzyme activities and low digesta viscosity. Notably, the group fed FBEs10% showed an increased villi height and a decreased crypt depth with a remarkable hyperactivity of duodenal glands. In addition, higher inclusion levels of FBEs boosted serum immune-related parameters and intestinal and breast muscle antioxidants status. Intestinal nutrient transporters encoding genes (GLUT-1, CAAT-1, LAT1 and PepT-1) and intestinal barriers encoding genes (MUC-2, JAM-2, occludin, claudins-1 and β-defensin 1) were upregulated with higher dietary FBEs levels. In conclusion, feeding on FBEs10% positively enhanced broiler chickens’ performance, feed efficiency and antioxidant status, and boosted intestinal barrier nutrient transporters encoding genes.

n experiment was conducted to determine and compare the differences in production performance, carcass characteristics and economic evaluation of broiler chicks fed two different dietary oil sources (Soybean oil and palm oil), during finisher phase, (5-6 wks.) of age, with different mixture products of probiotic with multi enzymes (Zado or Amphi-Bact each at 0.5 kg/ton). A total of 180 unsexed five weeks of age Hubbard broiler chicks were distributed equally in a completely randomized design with 2 oil sources (O) x 3 feed additives (F), resulting in 6 treatments with 3 replicates of 10 chicks each. The results indicated that live body weight (LBW), daily weight gain (DWG), daily feed intake (DFI) and feed conversion ratio (FCR) were not affected significantly by oil source (O), feed additives (F) and their interaction (O*F). The best performance index (PI) and production efficiency factor (PEF) were detected for the chickens fed diets incorporated with, soy oil (116.83 and 333.82) and Zado supplementation being (118.03 and 337.24), respectively. Protein conversion ratio (PCR) and energy conversion ratio (ECR) were improved in response to dietary palm oil and Zado supplementation without significant difference between treatments. Carcass traits, edible parts and drumstick traits were not altered by oil source (O), feed additives (F) and their interaction (O x F). Economic evaluation showed that, relative economic efficiency was improved for broiler chickens fed palm oil diets or soy oil + Zado (0.5 kg/kg) diets. Finally, it could be concluded that, using palm oil or soybean oil with Zado (0.5 kg/ton) in finisher diets of Hubbard broiler chickens enhanced economic efficiency without adverse effect on many performance traits.

Avian pathogenic Escherichia coli is one of the principal causes of heavy economic losses to the poultry industry. Little is known about the underlying mechanisms, particularly the potential role of immunoglobulin A and the DNA damage, involving the beneficial effects of dietary supplementation of probiotics and prebiotics in avian colibacillosis. The current study investigated the potential effects of probiotic and prebiotic dietary supplementation on E. coli-infected broiler chicks. A total of 120 1-day-old unsexed Hubbard chicks were divided into six groups: Group 1 was considered as a negative control; Group 2 was supplemented with 1 g/kg feed of Lactobacillus plantarum; Group 3 was supplemented with amylase enzyme; Group 4 served as a positive control infected orally by E. coli O78; Group 5 was supplemented with L. plantarum from 1-day-old chicken and then infected orally with E. coli O78; and Group 6 was supplemented with amylase enzyme from 1-day old chicken and then infected orally with E. coli O78. For all examined groups, the experimental period lasted for 42 days. The E. coli-infected group revealed a decrease in body performance parameters with a significant increase in the liver enzymes and renal function tests. The same group recorded a significant decrease in serum total proteins, albumins, and globulins, and the alteration of immunological parameters, antioxidant enzymes, oxidative stress parameters, and comet assay revealed highly damaged DNA in the liver and the intestine. By histopathological examination, a series of histopathological changes in the liver, the kidney, and the intestine were observed. The infected chick pretreated with probiotics or prebiotics demonstrated an improvement in body performance parameters besides a significant decrease in the hepatic enzymes and renal function tests. We noticed that, in treated groups, there was a significant increase in serum total proteins in the serum albumin and globulin levels, immunological parameters, and antioxidant enzymes. Furthermore, DNA damage and histopathological changes within hepatic, renal, and intestinal tissues were markedly diminished in the treated groups compared with the infected group. We concluded that the adverse effects of E. coli could be modulated through the chemopreventive administration of probiotics and prebiotics.
