The aim of this study to evaluate the effect of β-mannanase. Lysolecithin and Probiotic on some reproductive performance and hormone profile in female quail. Six hundred one day - old quail birds were randomly divided to four treatments (60 birds/treatment) with 3 replicates for each group treatment (20 birds / replicate) and at three duration periods. The first period 1-7 weeks, second period 7 - 13 weeks, third period 1-13 weeks. The group of study were control was fed on a standard ration. the second, third and fourth treatments were given β-mannanase. Lysolecithin. probiotic 0.5 g /kg ration respectively. Blood samples wear taken for blood serum analysis. including estimation of follicle- stimulating hormone and luteinizing hormone. The results revealed that the treated groups showed a significant increase in relative weight of the ovary and oviduct compared with control group. β-mannanase and probiotic groups showed a significant increase in the oviduct length compared with the control and Lysolecithin groups. There was a significant increase in the numbers of growing and mature follicles and weight of large follicle in all treated groups compared with control group. The 3^rd period showed a significant increase in the relative weight of ovary. oviduct and numbers of growing follicles. while the 2^nd and 3^rd period showed a significant increase in the oviduct length. About the interaction between treatments and periods. the best result appeared in the ovarian relative weight in the 3^rd period for probiotic and β-mannanase. the 3^rdperiod of probiotic showed a significant increase in the oviduct relative weight and for the oviduct length at 2^ed and 3^rd period for probiotic and β-mannanase. while 3^rd period of probiotic show best interaction in the numbers of growing follicles, as 2^nd and 3^rd periods showed better increase in the mature follicle's numbers and for large follicle weight in 1^st and 2^nd period of probiotic. The result also showed a significant increase in the FSH and LH level in all treated groups compared with control group. The 2^nd and 3^rd period were better significantly in the level of FSH and LH. Probiotic at 2^nd and 3^rdperiod showed a significant interaction on the level of FSH. On the other hand, 2^nd and 3^rd period for the β-mannanase and probiotic showed a better significant in the LH level. In conclusion. β-mannanase. Lysolecithin and probiotic supplementation to quail ration improved the hormonal status and enhance reproduction.
