Efficacy of in ovo delivered resveratrol (Trans 3, 4, 5-trihydroxystilbene) on growth, carcass weights, and blood metabolites of broiler chicks

Managing Gut Microbiota through In Ovo Nutrition Influences Early-Life Programming in Broiler Chickens

“…In ovo technology, through which a tiny quantity of material is injected into the bird’s egg/embryo during incubation, offers a novel alternative for delivering bioactive compounds to the chick embryo before hatching. Recent experiments from various researchers showed the benefits of in ovo feeding technology on body weight, feed conversion ratio, and pectoral meat yield [ 31 , 32 , 33 , 34 ].…”

Growing and laying performance of two different-plumage color Japanese quail varieties supplemented with corn silk in their diet

“…Additionally, the CS content of bioactive compounds (volatile oils, flavonoids, polyphenols, and organic acids) could have a role in improving birds’ growth as it exerts several beneficial effects on the health ( Hasanudin et al, 2012 ; Mesalam et al, 2021 ; Alagawany et al, 2022 ; Arain et al, 2022 ). Recently, Boeira et al (2022) reported that corn stigma can be considered a source of bioactive metabolites with antioxidant and antimicrobial activities and can be used as a natural antioxidant ingredient ( El-Fakhrany et al, 2021 ; El-Hindawy et al, 2021 ).…”

The use of Astragalus membranaceus as an eco-friendly alternative for antibiotics in diets of Japanese quail breeders

“…The poultry sector's primary objective is to deliver improved poultry productivity and safer food ( Khan et al, 2012 ; Saeed et al, 2019 , 2020 ). The literature revealed that the use of natural feed supplements as growth promoters in poultry feed positively impacts egg production, reproduction, and health and minimizes the use of antibiotics as growth enhancers ( Alagawany et al, 2019a , b , 2021 ; El-Fakhrany et al, 2021a ; Ny et al, 2021 ). Therefore, medicinal plants and their commodities have been employed in poultry feeds as a supplement to increase feed uptake, intestinal enzymes, immune functions, and growth and inhibit growth of harmful bacteria ( Dhama et al, 2018 , Al-Sagan et al, 2020 ; Abdel-Latif et al, 2022 ; Dong et al, 2023 ).…”
