“…In addition, the positive aspects of probiotics on intestinal histometric parameters in the present study can be linked to the modulation of the gut microbiota as healthy gut microbiota play effective roles in the performance of the host body such as nutrient utilization, digestibility, metabolism, immune responses, and prevention of intestinal disorders and homeostasis imbalances ( Balcázar et al., 2006 ; Laparra and Sanz, 2010 ; Rombout Jan et al., 2011 ; Best et al., 2017 ). Affirmative impacts of the use of probiotics on the tunica mucosa of the intestine have been reported in terms of a remarkable increase in villus height and Cd in the intestine of ducks fed with diets supplemented with probiotics ( Elhassan et al., 2019 ). Similarly, De Souza et al.…”

The potential impacts of probiotics on the performance and health status of white Pekin ducks fed with optimal or suboptimal dietary CP were evaluated during the growing period. A total of 180 male white Pekin ducks (14-day-old ducks with an initial weight of 415.65 ± 2.20 g) were randomly divided into 4 experimental groups (45 in each group of 5 replicates) in a 2 × 2 factorial design. The main factors included 2 dietary CP levels (18 or 14%) and dietary probiotic addition (with or without probiotics). The probiotic source was supplemented at 0.2 g per kilogram of diet from a blend of Lactobacillus acidophilus and Lactobacillus casei . The results showed that the diet containing 18% CP and probiotics significantly increases the final and total weight gain. Activities of intestinal enzymes (amylase, lipase, and protease), morphometrics (villus length, goblet cell count, and cryptal depth), and carcass percentage were also increased significantly. Total protein content, lysozyme activity, bactericidal activity, nitro blue tetrazolium levels, alternative complement pathway, superoxide dismutase activity, and catalase activity were significantly increased, whereas glucose, cortisol, and total cholesterol levels were decreased when treated with diet containing 18% CP and probiotics. Conversely, the group treated with diet containing 14% CP without probiotics showed the poorest performance, carcass properties, immune response, and antioxidant potential. In conclusion, probiotic addition to the 14% CP diet improved the performance of white Pekin ducks caused by reduced CP diet to performance due to the 18% CP diet without probiotic supplementation.

“…On the other hand, broiler diets supplemented with feed additives such as probiotics or acidifiers showed improved intestinal mucosal layer morphology and structural integrity of the small intestine, and consequently enhance nutrient absorption (Elhassan et al 2019). Accordingly, it is very important to find an accurate method for measuring the villus surface area.…”

Villus surface area (VSA) is measured to reflect the active absorption surface of the intestine under different experimental conditions. In context, it has been recommended to use a suitable model for calculating VSA of different shapes. However, no more attention has been paid to this point. Thus, a mathematical model, to calculate the VSA of ridge-like shape villi, was proposed for increasing the accuracy of VSA measuring. Then, to test the proposed model, a comparison between the common (tube-like) and proposed (ridge-like shape) models was done using real 416 villi morphometrics (height and width) of one-day-old specific pathogen-free broiler chicks. Also, Python program® was used to do a microcomputer simulation for comparing between models. Statistically, the apex surface area of the tube-like shape was greater than that of the ridge-like shape (P<0.0001). While the total VSA of tube-like shape villus was numerically greater than this of ridge-like shape ones. These results were confirmed by the simulation study. In conclusion, since the villus shape affects the VSA, the proposed model can be recommended for calculating the surface area of the ridge-like shape villi instead of the common ones. Besides villus morphometrics, the villus shape-surface area relationship can be used to explain the changes in absorption capacity and related economic parameters such as growth rate and body weight under different experimental conditions.

“…The branching of the villi is thought to be a morphological modification to increase the surface area of the small intestine (Okpe et al, 2016). In order to examine the beneficial effects of feed additives on the intestinal morphology of broiler chicks, several histological measurements have been adopted including the length and number of villi (Khan & Iqbal, 2016;Elhassan et al, 2019). Taken together, the number of branched villi in broilers might be considered as one of the tools utilized for the quantification assessment of the intestinal histology.…”

“…Despite the positive impacts of probiotics and acidifiers on broiler chicks, the reason to continue research on these additives not only is that the results are partly contradictory but also the scarcity of information documenting their combined effects (Agboola et al, 2015;Abudabos et al, 2017;Rodjan et al, 2017;Elhassan et al, 2019). Therefore, the present study was conducted to investigate the effect of the probiotic, Bacillus subtilis, and a blend of acidifiers, and their combination on the growth performance, gut morphology, and immunity of broiler chickens.…”

This study investigated the effect of a probiotic (Bacillus subtilis DSM 17299), blend of acidifiers, and their combination on the performance of broiler chicks. Two hundred and twenty unsexed one-day-old broilers (Ross 308) were randomly distributed into four groups (55 birds per group divided into 5 replicates) as 2X2 factorial arrangement including two factors, probiotic and blend of acidifiers, each of which had two levels: yes and no. Performance was determined weekly. Haemagglutination test was performed on blood samples taken on days 28 and 42 after the birds were injected twice (days 14 and 28) with 10% suspension of sheep red blood cells (SRBC). On day 42, tissue samples taken from the duodenum, jejunum and ileum were prepared for histology via scanning electron microscopy. During the first three weeks, dietary addition of probiotic significantly (p<0.05) increased body weight gain (BWG) while acidifiers significantly lowered (p<0.01) feed conversion ratio (FCR). Antibody titer against SRBC increased remarkably (p<0.01) 15 days post the first injection when probiotic was administered. The probiotic also increased (p<0.01) the number of the duodenal goblet cells, and the density of jejunal and ileal villi. Overall, the supplementation of probiotic or acidifiers enhanced the growth performance of broiler chicks, mainly during the first three weeks of age. The probiotic also improved the immune response and intestinal morphology of broilers. However, there was no evidence of synergy when probiotic and acidifiers were co-administered.
