Cím:	The prenatal window: Influence of leucine on growth and development of Japanese quail / Ndunguru Sawadi F., Reda Gebrehaweria K., Csernus Brigitta, Szabó Csaba, Lendvai Ádám Z., Czeglédi Levente

Megjegyzések:	Nutrients acquired during embryonic developmental stages entail part of the adult energy budget. The crucial time is during the perinatal period in birds when embryos absorb residual yolk prehatch and during the first few days of post-hatch. During this fragile period, intestinal and skeletal development occurs expeditiously, and chicks experience a significant physiological shift. We collected freshly laid Japanese quail (Coturnix japonica) eggs, weighed them, and then incubated them under standard conditions. We injected 2.5 mg/egg of leucine amino acid solution the tenth day after incubation, and the second group was injected with a physiological saline solution to serve as a control. Leucine treatment increased the hatching success and grew faster with increased body mass, and influenced the increase of wing, head, tarsal length, and gastrointestinal development more than the control from 5-days old chicks, tarsal length 3-days old chicks and wing length from 7-days old chicks consistently up to 21-days old than the control. Leucine did not influence the gastrointestinal development of day-old chicks but increased gastrointestinal development in 21-day-old chicks with significant interaction between treatment and age of chicks. In Ovo, leucine supplementation improved growth and development and enhanced hormonal expression. The adaptive changes in hormonal expression stored lifetime nutritional memory of early dietary experience, which improved growth and development essential for increasing production efficiency.
