TL;DR: Dietary supplementation of LGEO can improve the performance, lipid profile, immunity and antioxidant indices and decline intestinal pathogens and thus boost the health status of growing quail.

TL;DR: The effect of herbal additives on avian coccidiosis is based on diminishing the oocyst output through inhibition or impairment of the invasion, replication, and development of Eimeria species in the gut tissues of chickens.

TL;DR: D dietary supplementation with B. subtilis improved growth performance of broilers which may be related to the increased abundance of Blautia, Faecalibacterium, Flavonifractor, Hydrogenoanaerobacterium and Romboutsia, along with the decreased abundance of Odoribacter.

TL;DR: In this review, the impacts of prebiotics on the gut microbiome and physiological structure are discussed, emphasizing the poultry's growth performance.

TL;DR: Dietary MAPs alleviated AFB1-induced bursa of Fabricius injury through regulating Nrf2-mediated redox and mitochondrial apoptotic signaling pathway in broilers.

TL;DR: In this paper, the impacts of licorice (Glycyrrhiza glabra) on the growth performance, carcass traits, intestinal microbiota, liver and kidney functions, immunity, oxidative status, and lipid profile of Japanese quails were assessed.

TL;DR: In this paper, a review aimed to assess the benefits of using essential oils (EOs) and their nanoemulsions (NEs) as feed supplements for poultry and their potential use as antibiotic alternatives in organic poultry production.

TL;DR: Using BT and BB as feed supplements enhanced growth performance and meat quality of quails as well as diminished pathogenic bacteria proliferation in their diet and intestine.

TL;DR: In this paper, the authors evaluated the biofilm formation by a cocktail culture of 3 wild isolates of Salmonella enterica serotype on plastic (PLA), silicon rubber (SR), and chicken skin surfaces under various temperatures (4, 10, 25, 37, and 42°C) and pH values (4.0 to 6.0).

TL;DR: In this paper, the main objective of the study was to completely replace soybean in layer diets with defatted meal and fat from black soldier fly larvae without adverse effects for 5 × 10 Lohmann Brown Classic hens.

TL;DR: In this article, the authors focused on the causes of the increased mortality in broiler chicks during the first week of age and the methods used to minimize death and clinical signs associated with neonatal chicks' bacterial infections.

TL;DR: In conclusion, HS increased the circulating CORT level and subsequently caused muscle protein breakdown to provide amino acid substrates to liver gluconeogenesis responsible for energy supply.

TL;DR: Dietary ADP ameliorated the impairment of histology, cell apoptosis and immune balance in bursa of Fabricius of heat stressed broilers, which is involved in modulation of NF-κB signaling pathway.

TL;DR: It is suggested that the standard limit of ammonia concentration in adult poultry house is 15 ppm, which might make the broiler more sensitive to the changes of environment and pathogenic micro-organisms in the poultry house, and may be also a critical value that needs high alertness.

TL;DR: In this article, the effects of dietary supplementation with Bacillus subtilis or Bacillus licheniformis on growth performance, immunity, antioxidant capacity, short chain fatty acid (SCFA) production, and the cecal microflora in broiler chickens were investigated.

TL;DR: Dietary B. coagulans, when used as an alternative to antibiotics, improved body weight, average daily gain, antioxidant capacity, immunity function and gut health in broilers.

TL;DR: In this article, a review of C. perfringens-induced necrotic enteritis (NE) in broiler chicken is presented, which is a continuous challenge leading to high economic losses, especially after antimicrobial growth promoters in feeds were banned by many countries.

TL;DR: Dietary OEO supplementation can be a promising alternative to antibiotic growth promoters for improving poultry production and improved antioxidant status and intestinal health of broilers.

TL;DR: Broiler chickens fortified with clove seeds did not significantly affect the chickens' carcass characteristics and body composition, but an increment in weights of carcass components (liver, heart, and gizzard) was observed in low clove seed levels.

TL;DR: In this paper, the authors compared performance, immune response, leg health, carcass characteristics, and meat quality of a crossbred slow-growing broiler breed (SGB) with the conventional, fast-growing Cobb 500 broiler (CB) to assess their suitability as an alternative for chicken meat production in Australia.

TL;DR: Conclusively, although probiotic treatments (irrespective of the delivery route) did not affect growth performance, in ovo delivery of the probiotic product enhanced intestinal morphology, without compromising hatch performance and gut homeostasis.

TL;DR: Dietary supplementation of 200 and 300 mg/kg magnolol can improve hen performance, albumen quality of fresh and storage eggs, and hepatic lipid metabolism in the late laying cycle.

TL;DR: The results suggested that the use of SG and MG genotypes requires a specific dietary protocol to counteract the lipid oxidations in all the phases: in vivo, postmortem, and during/after cooking.

TL;DR: The data indicate a slight improvement of broiler meat quality and lipid nutritional value, without impairment of broilers' growth performance, thus supporting the usefulness of this microalga in poultry diets, up to this high level of incorporation.

TL;DR: To understand the mechanism of egg laying regulation, sequenced the hypothalamus and ovary transcriptome profiles in LP and HP using RNA-Seq and identified 10 potential candidate genes responsible for egg production in White Muscovy ducks.

TL;DR: This is the first report to confirm GoAstV can infect chickens while also providing an estimation of the evolutionary rates of Avastroviruses.

TL;DR: The results indicated that IAPS are effective in increasing the cecal beneficial bacteria and short-chain fatty acids production, contributing to improvement in the growth performance of immunosuppressive broilers.

TL;DR: Both Bacillus probiotics altered the intestinal and immune activities of broilers raised under suboptimal conditions, suggesting beneficial influence of probiotics.

TL;DR: Wang et al. as mentioned in this paper evaluated the effects of muscle fiber characteristics on meat quality traits in 45 female fast- and slow-growing ducks, including three duck breeds at typical market ages were selected and slaughtered, including fastgrowing ducks (Cherry Valley duck) and slow growing ducks (Small-sized Beijing duck and Liancheng White duck).

TL;DR: The YS tissue is a multifunctional organ that provides essential functions such as host immunity, nutrient uptake, carbohydrate and lipid metabolism, and erythropoiesis, and is an essential organ for the growth, development, and health of the developing embryo.
