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 3rd period showed a significant increase in the relative weight of ovary. oviduct and numbers of growing follicles. while the 2nd and 3rd 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 3rd period for probiotic and β-mannanase. the 3rd period of probiotic showed a significant increase in the oviduct relative weight and for the oviduct length at 2ed and 3rd period for probiotic and β-mannanase. while 3rd period of probiotic show best interaction in the numbers of growing follicles, as 2nd and 3rd periods showed better increase in the mature follicle's numbers and for large follicle weight in 1st and 2nd 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 2nd and 3rd period were better significantly in the level of FSH and LH. Probiotic at 2nd and 3rd period showed a significant interaction on the level of FSH. On the other hand, 2nd and 3rd 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.

This study was conducted on 32 of local Awassi ewes, average body weight 36.06±0.74 kg (aged 2-3 years, ewes were divided into two treatments. The first treatment (T1) the control contained 8 ewes fed on ration consist of barley, wheat bran, urea and wheat straw without supplement and the second (T2) was contained 24 ewes and fed on the same ration of control supplemented with protected amino acids (methionine 2.5 g and lysine 2.5 g) per ewe daily, the ewes were fed with restricted quantity 1 kg / ewe divided twice daily through the flushing and mating period which lasted 60 days, also all ewes was grazed for 6hr daily. Results was referred that protected amino acid supplement in T2 led to a significant (p<0.01) improvement in conception percentage 91.6%, prolificacy percentage 87.5% and lambing percentage 100% compared to T1 62.5%, 62.5% and 75% respectively, where is the differences was not significant in other traits. Blood parameters was showed significant (p<0.05) increase in glucose 67.91±2.06 mg/dl as compared to T1 59.25±1.72mg/dL, triglyceride was decreased significantly (p<0.05) in T2 42.66±0.96 mg/dl compared to T1 47.37±1.38 mg/dl. Concentration of AST enzyme was decreased (p<0.05) in T2 110.66±7.58 IU/l, while increased (p<0.05) ALT enzyme concentration 38.08±2.48 IU/l as compared to T1 which were 162.12±4.79 and 21.87±0.71IU/l respectively. In conclusion, Awassi ewes supplementation with protected methionine and lysine through flushing period enhance reproductive performance out of reproduction season.
