Storing semen at a temperature of 4 degrees Celsius reduces its motility and quality.
This study aimed to determine the effect of adding calcium compounds, including calcimaphor (CMP), calcium gluconate (CG), and calcium chloride (CaCl2), on the motility and progressive motility of rooster sperm kept at refrigerator temperature.
This research used five pieces of 45-week-old Lari breed roosters. The liquid diluent added different calcium compounds at 0.56, 0.056, and 0.0056 mM concentrations. After treatment, the diluted seminal samples were cooled at the storage temperature to avoid thermal doubt and then transferred to the refrigerator at 4 degrees Celsius. Parametric factors that were more important such as the percentage of laterality and progressive mobility, were measured visually using the lens of a 40-light microscope, survival was checked using the eosin-nigrosin staining method, acrosome health percentage by formalin citrate method, cell membrane health with hypoosmotic test, lipid peroxidation level, fertility was evaluated using perivitelline membrane sperm reaction 72 hours after storing at 4 degrees Celsius.
Based on the results, different calcium compounds in most concentrations could significantly affect the parameters of survival, mobility, and progressive mobility (P<0.05).
Most of the sperm-related parameters in the control group decreased after this period of storage in the refrigerator, but the addition of calcium gluconate (0.56, 0.056, and 0.0056), Calcimaphor (0.56, 0.056, and 0.0056) and calcium chloride (0.56, 0.056 and 0.0056) to the semen thinner maintained the quality indicators of rooster sperm.
