TL;DR: A comprehensive summary of the role of the microbiota in the broiler chicken gastrointestinal tract is presented, and the usefulness of different strategies for its modulation to control pathogens is discussed, with a particular emphasis on bacteriophages.

TL;DR: Light is shed on the benefits of using probiotics and/or prebiotics in poultry feed versus the risk of using antibiotics and the mechanisms by which they exert their effects, as well as the economic analysis of using these beneficial additives inoultry feed.

TL;DR: Dietary supplementation of 1 g/kg EA could alleviate heat‐stress‐induced compromised growth performance and intestinal damage of broilers.

TL;DR: The aim of the present paper is to provide a review of the effect on behavior and welfare of the different kinds of environmental enrichments in the production of broilers that have been described in the scientific literature.

TL;DR: Increasing levels of dietary TM meal inclusion in male broiler chickens may improve body weight and feed intake, but negatively affect feed efficiency and intestinal morphology, thus suggesting that low levels may be more suitable.

TL;DR: The present study investigated the meat quality and protein quality characteristics (pH, color, cooking loss, and shear force) in woody breast meat as compared tonormal breast meat and the differences in the muscle proteome profiles of woody and normal breast meat to provide additional information on the biochemical pathways and genetic variations that lead to woody Breast Meat.

TL;DR: In this article, the effects of phytate degradation on myo-inositol degradation in broiler chickens were investigated, including the disappearance of MI, P, Ca, and amino acids (AA) in different segments of the digestive tract.

TL;DR: One of the prerequisites of in ovo sex determination is a practicable method that can be used in industry, which needs to be rapid, cost‐efficient, and highly precise and negative impacts on hatching rate, animal health, and/or performance parameters should be limited.

TL;DR: The various methods employed for the in ovo administration of different materials for promoting the health and productivity of poultry are discussed in a review article as discussed by the authors, which includes vaccines, drugs, hormones, competitive exclusion cultures and prebiotics, and supplemental nutrients.

TL;DR: Results indicate that supplementation with Gln was effective in partially ameliorating the adverse effects of heat stress on intestinal barrier function in broilers by promoting epithelial cell proliferation and renewal, modifying the function of the intestinal mucosa barrier, and regulating the secretion of cytokines.

TL;DR: The outcomes indicate that MI might have been a relevant cause for the increase in G:F, and it is likely that the release of MI after complete dephosphorylation of phytate is one of the beneficial effects ofphytase, along with therelease of P and improvement in digestibility of other nutrients.

TL;DR: It was suggested that supplemental XOS can enhance the intestinal health and immune function of laying hens by positively influencing the intestinal characteristics, gut microbiota, cecal short‐chain fatty acids, and immune parameters.

TL;DR: It was concluded that curcumin supplementation enhanced the resistance of broilers to heat stress, as evidenced by reversing the FC, increasing the GSH content and GSH‐related enzyme activities, and inducing the expression of Nrf2 and NRF2‐mediated phase II detoxifying enzyme genes.

TL;DR: The results indicate that dietary supplementation with a combination of PA, BA, and MOS in broiler chickens could be used as an effective tool for controlling S. Typhimurium and promoting growth performance.

TL;DR: The results suggest that the synbiotic supplement may prove to be an important management tool for the broiler industry to diminish the negative effects of HS, potentially safeguarding the welfare and production of broiler chickens, particularly in areas that experience hot climates.

TL;DR: Data indicated that B. coagulans has a protective effect in SE infected broilers, and supplemented diets showed an increased trend in Fowlicidin‐2 mRNA levels (at 7 DPI) and a reduced trend in liver Salmonella load compared to the non‐supplemented control.

TL;DR: It is suggested that in broilers, ALA is more effective for normalizing the oxidative stress induced by DEX than vitamin C or vitamin E.

TL;DR: YSE exhibited a potential modulatory role against the LD‐induced inhibitory effects on the productive and reproductive performances of Japanese quails and YSE at 200 mg/kg diet was more effective than 100 mg/ kg diet in reversing theLD‐induced alterations.

TL;DR: High temperature influenced the bacterial composition and community structure of the ileal microbiota of broilers, specifically by increasing the species richness.

TL;DR: Adding Spirulina to the diet of broilers can improve antioxidant enzyme activity, dry matter and nitrogen digestibility, cecal Lactobacillus population, excreta ammonia gas emission, and 7 d drip loss of breast meat.

TL;DR: Hypoxia was the most likely cause/initiator of WS in broilers and it is speculated that birds suffering from WS have a vascular support system in muscle that is borderline adequate to support growth, but triggers like activity results in local hypoxia that damages tissue.

TL;DR: Bird production and quality responses of adding up to 7.5% defatted black soldier fly larvae meal (BSFLM) in a corn‐soybean meal diet fed to pullets (19 to 27 wk of age) and the effects of BSFLM on egg quality characteristics warrant further investigations.

TL;DR: The most prevalent manifestation of host defense in reaction to alterations in tissue homeostasis and is elicited by innate immune receptors that recognize and detect infection, host damage, and danger signaling molecules that activate a highly regulated network of immunological and physiological events.

TL;DR: The white recessive rock broilers showed poor heat tolerance as evidenced from the expression of HSP70 and the extent of histopathological damages, and the relative physiological and immunological parameters were worse in the WRR broilers than in the LS broilers.

TL;DR: Promoting an animal's capacity to mount a rapid, acute inflammatory response to control and contain the infection and the timely transition to anti‐inflammatory, tissue repair processes, and a homeostatic state are suggested as the optimum scenario to maintain anAnimal's resistance to pathogens and minimize non‐productive nutrient losses.

TL;DR: It can be inferred that, irrespective of implementation of improved biosecurity practices, seasonal variation can cause changes in the prevalence of Salmonella on the farms.

TL;DR: The results suggest that addition of 300mg/kg VC, 200 mg/kg VE or their combination could improve antioxidant ability and immune performance in oxidative‐stressed breeder roosters through up‐regulating the expression of GSH‐Px gene.

TL;DR: Meat quality was most favorable in the intensive broilers with the smallest shear force and thawing loss, whereas meat quality was not different between the other types.

TL;DR: It is demonstrated that it is possible to use Lactobacillus acidophilus D2/CSL (CECT 4529) in rurally reared chicken breeds with positive effects on performance and gut health.

TL;DR: The results of this study indicate that increased severity of WB fillets is associated with higher CF compared to normal fillets and there is a softening effect of the meat over time and data suggest that moisture (drip loss) and myofibril proteolysis (fragmentation) contribute to these changes.
