Effect of Moringa oleifera on semen quality profiles in endangered Teressa goat under tropical humid island ecosystem

Objective:To investigate the effect of Moringa oleifera leaf extract on semen quality parameters in Teressa goat buck.Methods:A total of 25 semen samples from six bucks were selected for the study.Spermatozoa of 150×10^(6) were incubated in 0,300,500 and 700μg of leaf extract as groupⅠ,Ⅱ,Ⅲ and Ⅳ,respectively.Liquid stored semen samples were analysed for motility,viability,total sperm abnormalities,plasma membrane,acrosomal and nuclear integrities,seminal plasma intracellular enzymes[aspartate aminotransferase(AST),alanine aminotransferase(ALT)and lactate dehydrogenase(LDH)]and total antioxidant capacity(TAC)and spermatozoa malondialdehyde(MDA)and cholesterol efflux in comparison with the control group(groupⅠ)for up to 72 h.Results:Moringa oleifera leaf extract(500μg/150×10^(6) spermatozoa)-treated semen had significantly higher motility,viability,plasma membrane,acrosomal and nuclear integrities,and TAC(P<0.05),and had significantly lower total sperm abnormalities,AST,ALT,LDH,MDA production and cholesterol efflux compared to those in other Moringa oleifera leaf extract treated(300 or 700μg/150×10^(6) spermatozoa)and control groups at different hours of liquid storage(P<0.05).Semen quality parameters and TAC showed an increasing trend and total sperm abnormalities,MDA production,leakage of intra-cellular enzymes and cholesterol efflux showed a decreasing trend from group Ⅰto group Ⅲand then an opposite trend from group Ⅲ to group Ⅳ at different hours of liquid storage.Conclusions:Moringa oleifera leaf extract 500μg/150×10^(6) spermatozoa can be used for liquid semen preservation in Teressa goat at Andaman and Nicobar Islands.

Prevalence of various pathological conditions in female buffaloes (Bubalus bubalis)

The present review article has described the prevalence of various pathological conditions of reproductive system of female buffaloes starting from ovary to vulva and vagina. Various pathological conditions were analyzed and tabulated as the total number of animal examined, number of the animals showed pathological lesions, percentage of animal showed various pathological lesions and percentage of individual pathological lesion in different parts of reproductive system of female buffaloes. The incidence of disorders of female genital organs of buffaloes has been reported by various authors at various percentages in different countries. The incidence of pathological conditions was recorded in clinically infertile cows after slaughtering or from apparently healthy buffaloes slaughtered for human consumption and/or based on postmortem examination. This review is comprehensively covering pathological conditions of female buffalo hitherto which was not previously described at one place. This review will provide a comprehensive knowledge about the prevalence of different pathological condition of different parts of reproductive tract of female buffaloes. The review has six numbers of tables described about the various pathological conditions from ovary to vulva and vagina in female buffaloes. The present review article will be very useful to the buffalo farmers, buffalo breeders and researchers are working in buffalo reproduction & breeding and pathology.
