EFFCET OF DIETARY SUPPLEMENTATION WITH DIFFERENT LEVELS OF FENUGREEK SEEDS (Trigonella foenum graecum ) ON SEMEN QUALITY AND HISTOLOGICAL TESTIS TRAITS OF JAPANESE QUAIL (Coturnix coturnix japonica )

Abstract

This study was conducted to evaluate the effect of the addition of fenugreek seeds (F.S) to the Japanese quail males ration on semen quality and testis histological traits. A total of 28 males (125 day old) divided into four groups (7 males/group) and treated as follow T1 =control group reared on standard ration,T2 = standard ration supplemented with 5gm F.S /kg , T3= standard ration supplemented with 10gm F.S /kg, T4= standard ration supplemented with 15gm F.S /kg . Semen samples were assessed after four weeks of treatment as regards ejaculation volume , spermatozoa motility ,viability and semen concentration and testis traits which involved testis weight , seminiferous tubules diameter(S.D), seminiferous tubules lumen diameter (L.D) germinal layer thickness (G.T) and germinal layer area(G.A) and seminiferous tubules lumen area (L.A) . Results revealed that the treatment (T2,T3 and T4) resulted a significant (p≤ 0.05) improvement in ejaculation volume , spermatozoa motility ,viability and semen concentration in comparison with control group (T1) . The testis weight , seminiferous tubules diameter, germinal layer thickness and germinal layer area showed significant increase (p≤ 0.05)in fenugreek seeds groups as compared with control group. Seminiferous tubules lumen diameter and lumen area were increased significantly in control group as compared with the fenugreek seeds treatment .In conclusion , the supplementation of F.S to the Japanese quail males ration will improve semen quality traits and sustain the histological traits of the testis.
