L-serine modulates activities of antioxidant enzymes and behavioral responses in broiler chickens subjected to feed restriction during the hot-dry season

Growth performance, liver and kidney functions, blood hormonal profile, and economic efficiency of broilers fed different levels of threonine supplementation during feed restriction

“…In the current investigation, feed-restricted broilers had reduced T4 during the feed restriction phase. This may result from the birds conserving energy with a low basal metabolism ( Zhan et al, 2007 ; Ogbuagu et al, 2023 ). Nevertheless, there was no statistically substantial difference between the 2 feed-restricted and ad libitum birds regarding the level of T3.…”

“…Broiler production is characterized by a fast growth rate linked with impaired reproductive competence, ascites, lameness, and mortality. Hence feed restriction has been applied ( Ebeid et al, 2022 ; Ogbuagu et al, 2023 ).…”

Impact of early feed restriction and continued supplementation with coated organic acid and essential oils on sustainability of laying performance, egg quality, fertility, hatchability, immunity status, and gut microbiota of Japanese quail hens

“…Even if poultry meat production is, in general, characterized by a fast growth rate, the feed restriction (FR) has been applied in broilers also the last years (Ebeid et al, 2022;Ogbuagu et al, 2023). This nutritional strategy, which reduces the feed consumed by the animals, can be considered also a valuable way to reduce the negative effects on the ingredients availability due to the recent global crisis (COVID pandemic and Russia−Ukraine war) affecting feed supply and chain (Hafez and Attia, 2020).…”
