Evaluation of the effectiveness of ginger extract on various specialized indicators of sperm motility, testicular weight, hematology and immune response in fowls

چکیده مقاله

The aim of our study was to evaluate the effectiveness of Ginger in improving sperm fertility indices in poultry. Ginger extract (0.5, 1.0 and 2.0 g/L, for two weeks) was added to the drinking water of 36 adult roosters. Then, specific sperm fertility indices including percentage of motile sperm, fast progressive movements, slow progressive movements, abnormal movements, active sperm and specialized sperm motility index were measured. Hematology indices, immunity titer against Newcastle disease vaccine and testis weight were also determined. The highest number of sperms with fast progressive movements, the highest amount of active and motile sperms and the lowest amount of structural and motor abnormalities of sperm were observed in concentrations of 1 and 2 g/L. Ginger had no effect on hematology, immunity and testis weight. Adding Ginger to the diet of breeder roosters can improve sperm fertility, which leads to increased hatchability.
