“…There was no interaction (P > 0.05) between diet type and additives for blood parameters (Table 5). Blood parameter analysis is an important tool to assess health status and to detect abnormalities in poultry metabolic changes that may have occurred (Nunes et al, 2018;Eler et al, 2019). In general, the blood values of broilers fed different treatments were within normal ranges.…”

The objective of this study was to evaluate the use of a combination of essential oils, prebiotics and antibiotics on broiler production. The treatments consisted of a normal diet meeting the nutritional requirements, and diets with a 5% reduction of nutritional requirements, supplemented or not with antibiotics (En+Sal) (10 g ton-1 enramycin and 125 g ton-1 salinomycin) or a blend of essential oils (EOFOS) (oregano, anise and lemon) plus fructooligosaccharides (125 g ton-1). A total of 1,152 male one-day-old broilers were randomized by weight and distributed into a 2*3 factorial design, consisting of six treatments with each treatment containing eight replicates of 24 birds per experimental unit. The Student-Newman-Keuls test was performed at 5% probability. Broiler performance was evaluated at 10, 21 and 42 days, intestinal morphometry was evaluated at 21 days, microbiological cecum counts at 33 days, blood parameters at 35 days and carcass and cuts yield at 42 days of age. Broilers fed reduced diets had a reduction in performance (P < 0.05). There was an interaction (P < 0.05) between diet type and prebiotics for jejunum villus height and villus height:crypt depth ratios for all intestinal segments. There was no effect (P > 0.05) of growth promoters and diet type on the Lactobacillus and Bifidobacterium populations within the gastrointestinal tract. There were no differences for duodenum or ileum villus heights (P > 0.05). Broilers fed EOFOS showed higher villus height in the jejunum at 21 days. There were no effects on blood parameters of different diets and growth promoters (P > 0.05), nor on carcass and cuts yield, abdominal fat and relative liver weight (P > 0.05). Broilers receiving the normal diet with EOFOS showed higher villus height in the jejunum at 21 days when compared to the normal diet with antibiotics and the normal diet without growth promoters. However, there were no effects of growth promoters and diet type on broiler performance at 42 days.

Phytogenic Compounds for Enhancing Intestinal Barrier Function in Poultry–A Review

et al. 2021

View full text Add to dashboard Cite

After the European Union ban of antibiotic growth promoters, works on different methods of improving gut health have intensified. The poultry industry is struggling with problems that were previously controlled by antibiotic growth promoters, therefore the search for optimal solutions continues. Simultaneously, there is also increasing social pressure to minimize the use of antibiotics and replace them with alternative feed additives. A variety of available alternatives is considered safe by consumers, among which phytogenics play a significant role. However, there are still some limitations that need to be considered. The most questionable are the issues related to bioavailability, metabolism of plant derivatives in birds, and the difficulty of standardizing commercial products. There is still a need for more evidence-based recommendations for the use of phytogenics in livestock. On the other hand, a positive influence of phytogenic compounds on the health of poultry has been previously described by many researchers and practical application of these compounds has auspicious perspectives in poultry production. Supplementation with phytogenic feed additives has been shown to protect birds from various environmental threats leading to impaired intestinal barrier function. Phytogenic feed additives have the potential to improve the overall structure of intestinal mucosa as well as gut barrier function on a molecular level. Recognition of the phytogenicsʼ effect on the components of the intestinal barrier may enable the selection of the most suitable ones to alleviate negative effects of different agents. This review aims to summarize current knowledge of the influence of various phytogenic constituents on the intestinal barrier and health of poultry.

“…Consistent with our results, an earlier study [ 7 ] reported that the addition of herbal components, including carvacrol and thymol, to coccidial-challenged broiler chickens did not affect carcass weight. Alternatively, [ 49 ] observed that the addition of oregano essential oil, such as carvacrol and thymol, to broiler diets increased carcass yield. Considering this, further studies related to carcass yield between infected broilers and phenolic compounds are required.…”

This study was conducted to evaluate the efficacy of a combination 3, 4, 5trihydroxybenzoic acid (THB) and oregano extracts (i.e., Carvacrol and Thymol) at intake/dietary different levels on growth performance, intestinal health indicators, immune responses and fecal oocyst shedding in broiler chickens under Eimeria challenged condition.A total of 336 one-day-old broilers were randomly assigned to one of six dietary treatments with seven replications per treatment. Dietary treatments were: i) Non-challenged bird without any dietary treatment (NCNT), ii) Challenged bird without any dietary treatment (CNT), iii) Challenged birds fed a THB diet (0.1 g/kg, THB), iv) Challenged birds fed a combination of THB and oregano extracts diet (0.1 g/kg, COM 100), and a gradual increase of combination of THB and oregano extracts likely v) 0.15 g/kg (COM 150), and 0.2 g/kg (COM 200). On day 14, all groups except for NCNT have orally challenged with a 10-fold dose of Livacox ® T anticoccidial vaccine to trigger coccidiosis. The results indicated that Eimeria-challenged broilers fed COM 100 and COM 200 diets increased (P < 0.05) body weight (BW) than CNT diet on day 35. Furthermore, birds fed COM 100 and COM 200 diets increased (P < 0.05) average daily gain compared to those fed CNT diets for the entire experimental period. There is no significant (P > 0.05) in average daily feed intake, feed efficiency between NCNT and birds fed with combined THB and oregano extracts for the entire experimental period. A combination of THB and oregano extract regardless of concentration levels or THB alone reduced (P < 0.05) lesion score in ileum compared to the CNT diet for 7 days post-infection (dpi). Birds fed COM 100 diet had lower (P < 0.05) intestinal lesion scores in jejunum and caeca on 7 dpi compared to those were in the CNT diet. No (P > 0.05) difference was observed in the oocysts per gram of feces (OPG) count, intestinal morphology, carcass traits and blood cytokine concentration among the infected treatments. Collectively, we conclude that birds fed A C C E T E Dwith a combination of THB and oregano extracts regardless of the ratios that were used demonstrated better recovery of health after the coccidial challenge than using only THB alone.
