BACKGROUND: Sugars are the energetic source for sperm to maintain the metabolic process, and the antibiotics slow down sperm degradation. OBJECTIVE: To study the effects of rosemary honey as energy source and cryoprotectant in combination with garlic as a natural antibiotic
on the quality of ram spermatozoa upon cooling. MATERIALS AND METHODS: The ejaculates from three rams were evaluated at different times during cooling to determine its post-dilution quality. RESULTS: Glycerol and dimethylformamide in conjunction with honey and garlic significantly
improve the survival of spermatozoa. CONCLUSION: The addition of honey and garlic reduces sperm deterioration when stored at 4°C.
