Effect of a Diet Supplemented with the Moringa oleifera Seed Powder on the Performance, Egg Quality, and Gene Expression in Japanese Laying Quail under Heat-Stress.

ABSTRACT: This study was conducted to evaluate the effect of three concentrations of the Moringa oleifera seed powder as a feed supplement on the productive performance and egg quality traits of laying Japanese quail (Coturnix japonica) exposed to heat stress. The expression patterns of the genes estrogen receptors (ESR2), follicle-stimulating hormone receptor (FSHR), prolactin receptor (PRLR), and steroidogenic acute regulatory protein (STAR) were estimated in ovaries, using a quantitative real-time polymerase chain reaction. A total of 200 laying quail aged seven weeks were randomly allocated to the following four experimental groups-the control (CNT), T1, T2, and T3 groups; each group comprised 50 quail females with 5 replicates (10 per group). The CNT group was fed a basal diet, whereas the T1,
