Effects of split feeding on performance, egg quality, and bone strength in brown laying hens in aviary system

Effects of feeding strategies during lay on broiler breeder production performance, eggshell quality, incubation traits, and behavior

“…More recently, a novel feeding strategy in layer hens was applied in which birds were fed via a split-feeding (specific morning and afternoon diet) program to facilitate egg and eggshell formation ( de Los Mozos, 2014 ; Molnár et al, 2018 ). The specific morning diet contained more energy, protein, and phosphorus ( P ) and less Ca than a standard breeder diet, where the afternoon diet had a lower energy, protein, and P and higher Ca content than a standard breeder diet.…”

Lighting, density, and dietary strategies to improve poultry behavior, health, and production

“…The prolonged fasting durations may negatively influence the hypothalamus regarding reduced gonadotropin secretion, which ultimately negatively affects ovulation, leading to reduced egg production (Morris and Nalbandov 1961). As far as the commercial layer is concerned, split feeding strategies in organic farming (van Krimpen et al 2018) and aviary system (Molnár et al 2018) did not affect egg production. Twice a day feeding system did not also affect the egg weight of commercial layers (Samara et al 1996;Backhouse and Gous 2005;Soltanmoradi et al 2013;Londero et al 2015Londero et al , 2016.…”

“…De Jong et al (2005) Performance, egg quality, and bone strength Laying hens The split feeding system showed a potential strategy to improve shell quality by offering a better match between Ca supplementation and requirements in the laying hen Molnár et al (2018) Performance, eggshell quality, incubation traits, and behavior Laying hens Twice a day feeding improves behavior and split feeding improves both egg production and behavior in broiler breeders. However, no effects were observed on eggshell quality and incubation traits van Emous et al (2021) Balanced dietary electrolyte, i.e., Na, K, and Cl, is generally considered a major factor influencing the quality of litter and the severity of FPD in broiler chickens.…”

“…Doordat leghennen steeds robuuster worden en langer worden aangehouden, produceren de dieren momenteel meer dan 400 eieren in hun productieve leven van circa 80 weken (Hyline, 2018;Lohmann, 2016;Novogen, 2017). De verwachting is dat dit aantal zal toenemen tot boven de 500 eieren in ongeveer 100 weken (Molnár et al, 2018).…”
