متن کاملThe Effect of Semen Storage Temperature and Diluent Type on the Sperm Quality Index of Broiler Breeder Semen
The sperm quality index (SQI) is predictive of fresh semen quality. Our objective was to examine if semen storage affects the SQI obtained from undiluted semen, or semen diluted with either Beltsville Poultry Semen Extender (BPSE) or Minimum Essential Medium (MEM) and held for 8 h at 4, 21, or 41 C. Dead o sperm percentage was higher and SQI was lower from undiluted versus diluted semen. Dead s...
