Sperm sexing represents the most promising approach for production of genderspecific livestock under commercial settings. Flow cytometry is currently the method of choice for sexing sperm cells, but remains costly, has low throughput and lowers fertility in vivo. Thus, the study was aimed to test Percoll density centrifugation for sexing sperm cells in small ruminants. Semen from both rams (n = 4) and bucks (n = 4) was collected by electro-ejaculation, cryopreserved and further used for Percoll density centrifugation (PDC). Sperm sexing was confirmed by conventional PCR by determining the ratio of X and Y-bearing sperm cells. The semen before and after PDC in goats did not alter proportion of X-bearing (30%A vs 28%A; 34%A vs 41%A; 55%A vs 56%A; 42%A vs 40%A) or Y-bearing (70%A vs 72%A; 66%A vs 59%A; 45%A vs 44%A; 58%A vs 60%A).
