    The present investigation focuses on the evaluation of changes in semen quality in New Zealand breed rabbits (Oryctolagus cuniculus) of 6 months, 1 year and 2 years of age. The main objective of the study is to analyze how age affects semen quality parameters in this specific breed. For this purpose, weekly fresh semen collections were performed using an artificial vagina and a female dummy, evaluating both macroscopic and microscopic semen parameters. Analyses included volume, color, motility, sperm consistency, sperm morphology and appearance of fresh semen. The results showed that 1-year-old rabbits presented better semen quality in terms of vitality and concentration, with a lower amount of sperm abnormalities compared to 6-month-old and 2-year-old rabbits. It was determined that age is a significant factor in semen quality in New Zealand breed rabbits. In addition, it is emphasized that dietary supplementation and collection technique do not significantly alter the parameters evaluated, as long as adequate conditions are maintained during the process.
