“…The large intestine, particularly the cecum, has been rarely assessed in intestinal morphometric studies. In a recent study on the effects of essential oils and organic acids, no significant differences were reported in these segments [31]. In our study, however, cecal crypt depth proved to be a relevant parameter in our assessment of the impact of FDA on mucosal morphology.…”

“…The majority of these studies focused on the small intestine, mainly the jejunum mucosa, with only a few evaluating the duodenum [30][31][32][33][34][35][36][37], despite its very high absorption potential [38]. In one case, supplementation with bamboo vinegar or polyunsaturated fatty acid from an extruded flax product resulted in a significant increase in duodenal villi height in aged hens, suggesting that diet composition affects the duodenal mucosal structure [29,36].…”

“…It is important to study the molecular and metabolic mechanisms behind the productive parameters in order to correctly manage animal feed [19]. In poultry, as in other species, the intestinal microbiota collectively acts as a metabolic organ, facilitating nutrient absorption and the immune response against pathogens [31,43]. Microbiota is determined by host genes and the environment, with diet being one of the most important factors.…”

“…Microbiota is determined by host genes and the environment, with diet being one of the most important factors. Modifications in dietary composition may, therefore, induce changes in microbiota [31]. Microbiota composition in poultry, especially in laying hens, has become an important area of research in veterinary medicine [27].…”

Effects on Intestinal Mucosal Morphology, Productive Parameters and Microbiota Composition after Supplementation with Fermented Defatted Alperujo (FDA) in Laying Hens

The olive oil sector is currently adapting its traditional function to also become a supplier of high-value by-products that possess antioxidant, anti-inflammatory and antimicrobial properties. In this study, we evaluated the effect of the fermented defatted alperujo (FDA) on the intestinal health of laying hens. The morphology of the duodenal and cecal mucosa, the composition of the intestinal microbiota and the productivity of a batch of laying hens were evaluated after FDA supplementation. At early life stages, significant differences (p < 0.001) were observed in duodenal villi height and in crypt depth of both the duodenum and the cecum in the FDA-supplemented group, indicating improved intestinal health in this group. Microbiota composition in the hatchery group supplemented with FDA had a higher abundance of Actinobacteria, Firmicutes and Proteobacteria, and higher bacterial diversity. During the production period, significant differences (p < 0.05) were observed in the number of broken eggs from the supplemented group. We conclude that FDA supplementation improves the absorption capacity of the intestinal mucosa and modifies the intestinal microbiota to favor a greater immune response, leading to an increase in egg production.

“…All tested blends reduced the crypt depth of the ileum that resulted in improved VH: CD ratio, which is an indicator of the absorptive capacity of the small intestine [45]. Several authors [44,46,47] pointed out their promoting effect on the development of gastrointestinal mucosa and villus height. In fact, enteric infection may damage the epithelium and compromise villus height leading to increase crypt depth indicating greater enterocyte-cell flow, and more steady cell-renewal rate within the digestive tract usually resulted from the increased sloughing [48].…”

An experiment was performed to evaluate the effect of four different microencapsulated blends of organic acids (OA) and nature-identical aromatic compounds (AC) on growth performance and gut health of broilers challenged with a recycled NE litter. A total of 600 one-day-old male Ross 308 broilers were randomly assigned to five treatments consisting of a basal diet (as negative control) supplemented with each of the tested microencapsulated blends: OA1 (malic and fumaric acid) + AC; 2.5 g/kg; OA2 (calcium butyrate+fumaric acid) + AC; 1.7 g/kg; MCFA (capric-caprylic; caproic and lauric acid) + AC; 2 g/kg; and MCFA + OA3 (calcium butyrate+fumaric and citric acid) + AC; 1.5 g/kg. The AC used was the same for all treatments; including cinnamaldehyde, carvacrol, and thymol (8:1:1), as major compounds. Three tested blends enhanced growth performance by improving intestinal histomorphology (p < 0.001). The tested blends enhanced the abundance of some beneficial families such as Ruminococcaceae and Lachnospiraceae; while reducing that of harmful ones such as Enterobacteriaceae and Helicobacteraceae. A further dose-response experiment showed that 0.5 g/kg of the blend 2 and 2 g/kg of the blend 4 improved growth performance and intestinal histomorphology of chickens on d 42 and decreased fecal Enterobacteriaceae and C. perfringens counts. Similar effects to the previous experiment were observed for cecum microbiota.

BACKGROUNDThis study aimed to determine the effects of a mixture of glycerol monolaurate and cinnamaldehyde (GCM) supplementation on the laying performance, egg quality, antioxidant capacity, and serum parameters of laying hens. A total of 1120 14‐week‐old Jingfen‐1 strain laying hens with similar performance were randomly allocated to four dietary treatments: control, and GCM groups supplemented with 250, 500, or 1000 mg kg−1 for 12 weeks.RESULTSCompared with the control group, GCM‐supplemented groups significantly reduced (P < 0.05) the rate of unqualified eggs of laying hens aged 17–24 weeks. Supplementation of GCM significantly increased (P < 0.05) yolk color and serum glutathione peroxidase (GSH‐Px) activity but decreased (P < 0.05) the hydrogen peroxide (H2O2) content in the serum of laying hens at the age of 20 weeks. Furthermore, groups supplemented with GCM showed a significant increase (P < 0.05) in Haugh unit, yolk color, activities of total superoxide dismutase and GSH‐Px, and the glucose content in serum, and a decrease (P < 0.05) in the content of urea nitrogen and H2O2 and malondialdehyde in serum of laying hens at the age of 24 weeks. 500 mg kg−1 GCM supplementation significantly increased (P < 0.05) the number of large white follicles and 1000 mg kg−1 GCM supplementation decreased the number of large yellow follicles in 28‐week‐old laying hens.CONCLUSIONThese results indicated that GCM supplementation has positive effects on reducing egg loss and improving egg quality in the early laying period of laying hens. © 2023 Society of Chemical Industry.
