“…The effect of a number of natural feed additives against Campylobacter spp. colonization in poultry has been previously studied by Kurecki et al [25]. However, the used compounds were not comparable to the bioactive molecules considered in this study and the results were not consistent.…”

Food wastes are sources of compounds that can be used as natural additives in the food and feed industry. The olive oil industry produces two main wastes: aqueous waste (olive mill wastewater) and solid waste (pomace or olive cake). These by-products are rich in phenols, which are antioxidant and antimicrobial compounds able to inhibit or delay the growth of several bacteria in vitro. The dietary effect of both olive mill wastewater polyphenolic extract (OMWPE) and dehydrated olive cake (DOC) on the prevalence of Campylobacter spp. in broiler chickens was investigated. A commercial basal diet was supplemented with either OMWPE-or DOC-enriched maize at two dosages (low: 16%; high: 33%). The prevalence of Campylobacter spp. shedding was evaluated at 21, 35, and 49 days of age. The prevalence of Campylobacter spp. differed among groups only at 49 days of age. Both OMWPE groups showed a lower (p < 0.05) prevalence compared to the control group. The odds ratio evaluation showed that the higher dose of OMWPE reduced the possibility of shedding 11-fold compared to the control group (p < 0.001). These results highlight the potential use of olive by-products against Campylobacter spp. in poultry.

“…However, there are two acceptable mechanisms to understand the effect of these essential oils. The first one considers the promotion of digestive enzyme secretion, and the second deals with the gut microflora ecosystem stabilization, leading to enhanced utilization of food and decreased exposure to growth-depressing disorders that could be related to the metabolism and the digestion processes [44][45][46]. Several chicken studies have documented positive effects of essential oils on the digestive enzyme (pancreatic α-amylase and intestinal maltase) secretion and intestinal mucosa [47,48].…”

Housing system and nutrition are non-genetic factors that can improve the well-being of animals to obtain higher quality products. A better understanding of how different housing systems and essential oils can influence the performance of layers is very important at the research and commercial levels. The current study aimed to investigate the effects of a housing system and dietary supplementation of rosemary and cinnamon essential oils on layers’ performance and egg quality. A factorial arrangement (2 × 3) was performed include two housing systems (floor and cage) and three different types of essential oils (0, 300 mg/kg diet of rosemary and 300 mg/kg diet of cinnamon essential oils) to study their effects on the productive performance, egg quality, immunity, oxidative stress and haematology of ISA brown laying hens during the production stages (from 28 to 76 weeks of age). Birds were randomly divided into two groups each comprising of 1500 birds; the first group was moved from the litter to reared laying cages while the second group was floor reared. Each group was randomly divided into three groups, the first was considered as a control group, the second treated with rosemary essential oil, and the third with cinnamon essential oil. The differences in egg production and weight, egg quality, feed intake and conversion, blood picture and chemistry, immunity, and antioxidant parameters between the different housing systems (floor and cage) were not significant at (p < 0.05 or 0.01). On the other hand, the egg production and weight, Haugh unit, feed intake and conversion, blood cholesterol, Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), urea, Ca, P, immunity, and antioxidant parameters were significantly (p < 0.05 or 0.01) better in rosemary and cinnamon groups than in the control group. Furthermore, the results of dietary supplementation with rosemary and cinnamon were very close. Regarding egg production and weight, there were no significant differences due to the interactions. The differences in egg mass among the interactions were also not significant except at 68–76 weeks, where the cage × cinnamon group was the highest. Under the floor rearing system, birds that were fed a diet supplemented with or without essential oils (EOs) consumed more feed than those raised under the cage system. Regarding feed conversion rate (FCR), the differences among the interactions were not significant except at 44–52, 52–60 and 68–76 weeks, where the cage × cinnamon group was the lowest. Excluding glutathione peroxidase (GPx) activity (p < 0.001), all immunity and antioxidant indices were not statistically different as a consequence of the interaction among EOs and housing systems. Additionally, the highest levels of phosphorus were observed for layers fed diets enriched with cinnamon oil with the cage or floor system. In conclusion, the data suggested that supplementation of rosemary and cinnamon essential oils in laying hen diet showed significantly positive effects on hen performance and egg production. Cholesterol, liver and kidney functions, immunity, and antioxidant parameters improved with rosemary and cinnamon supplementation when compared to the control. Additionally, the different housing systems did not result in any positive or negative impact on these traits.

“…As a result, it became necessary to seek for viable alternatives that could enhance the natural defense mechanisms of animals and reduce the massive use of antibiotics. Alternatives like prebiotics (Heidarpour et al, 2011), synbiotics (Agboola et al, 2014), organic acids (Fernandes et al, 2014), phytobiotics (Gheisar and Kim, 2017), plant extracts (Kurekci et al, 2014), acidifiers (Markazi et al, 2019), etc. have been found to play an important role in improving growth performance, maintaining microbial balance and enhancing gut integrity in poultry (Hosseini et al, 2016).…”

This study was carried out to investigate the effects of enzyme, probiotic or their combinations on growth response, microbiota and gut histopathological indices of broiler chicken. One hundred and fifty (150) one-day old unsexed Arbor Acre broiler chicks were weighed and randomly allotted to 5 dietary treatments; each diet had 5 replicates of 6 birds each in the study that lasted for 42 days. Treatment 1 consists of the basal diet (negative control; NC): Treatment 2 was NC+0.1% antibiotic (positive control), Treatment 3: NC+0.4% probiotic, Treatment 4: NC+0.1% enzyme and Treatment 5: NC+0.4% probiotic+0.1% enzyme. Performance indices were measured. On day 42, ileal digesta was collected from two birds per replicate for microbial count while about 5 cm of distal ileum was severed for histopathology. The results showed that diets had no significant (p>0.05) effect on the performance of birds at the starter and finisher phases. Total heterotrophic counts of birds fed with basal and probiotic diets were similar but significantly (p<0.05) higher than other diets. The highest Lactobacilli count was recorded in the mixture of probiotic + enzyme diet while least was observed in probiotic (2.58×105 cfu/ml) and enzyme supplemented diets (1.45×105 cfu/ml). Total coliform count of birds fed antibiotic diet was significantly (p<0.05) lower (14.12×105 cfu/ml) than for those on other diets. Total Escherichia coli count was highest in birds fed antibiotic while least was observed in birds fed mixture of probiotics + enzyme diet. Photomicrographs of the ileum of birds fed basal diet showed sloughed mucosa layer and degenerated villi. However birds fed antibiotic, probiotic, enzyme or probiotic+enzyme diets showed normal mucosa layer with normal villi, the lamina proprial showed normal tissues with mild infiltrate. In conclusion, feed supplements used in this study can serve as viable alternatives to antibiotics in broiler nutrition without compromising birds’ health
