Abstract
This study aimed to investigate the effect of MOl or MOS supplementation some blood constituents, semen characteristics, testis and epididymis measurements in Barki rams. Fifteen Barki rams aged 10-12 months divided into three similar groups (5each). Rams in G1 were fed the basal diet supplemented by MOL (5%of CFM), rams in G2 fed the basal diet supplemented by MSC (10%of CFM) while rams in G3 (control) were fed the basal diet without supplements. Blood samples were collected and erythrocytes, Hb, PLT, PCV, MCV, MCH, MCHC, ALT, AST, glucose, uric acid, creatinine and testosterone were determined. Semen was collected and semen physical characteristics as well as of the epididymis and testes biometric were evaluated.
Results indicated that MOL and MSC supplementation to ram rations significantly affected glucose, creatinine, urea, ALT, AST and testosterone levels, and insignificantly on erythrocyte, Hb, PLT, PCV, MCV, MCH, MCHC, ALT, AST levels.
In this regard, MOL supplementation to ram rations increased MCV, PLT and decreased RBCs, Hg, MCH, MCHC, and PCV; while, MSC supplementation increased RBCs, Hg, MCHC, PLT, and urea. The addition of MOL or MSC increased ALT, AST, and creatinine, and decreased testosterone and glucose levels.
Both supplementation (MOL or MOS) in Barki rams' feed improved most characteristics of semen such as volume, motility, vitality and normality, and reduced mortality and abnormalities and there is no significant effect on testes measurements. The highest testicular weight and width were observed in the MOL group.
