Semen cryopreservation is associated with low productivity results. This study aimed to test the Coconut Water Powder (ACP®-103) as a ressuspension diluent after thawing semen, also evaluate sperm quality during the cooling curve until thawing of the semen. For this, the semen was collected from 15 boars once a week, incubated at 30 °C for 15 minutes, and afterwards, the samples were diluted in the diluent Beltsville Thawing Solution – BTS (Control) or ACP-103®, and subjected to a slow cooling curve, where the force and the motility were analyzed in each step. The thawed semen was ressuspended in its respective solvents and analyzed in the characteristics of vigor, motility, vitality, acrosome integrity and functionality of the membrane. During the analysis of vigor and motility that make up the cooling curve, and thawing, for analysis of vitality and intact acrosomal membrane, it was observed that there was no significant difference between treatments. Besides, after thawing, the BTS showed better results of sperm vigor, sperm motility and membrane functionality. However, the cooling curve and coconut water powder can be used in the protocol for cryopreservation of boar semen, as both ensured quality of sperm viability that may be used in artificial insemination.Keywords: Swine semen; alternative extender; freezing; sperm viability.
