Effects of long term storage of semen in liquid nitrogen on the viability, motility and abnormality of frozen thawed Frisian Holstein bull spermatozoa

Conclusions Based on the results in these experiments, it may be concluded that concentration sperm during one year storage in liquid nitrogen resulted in similar concentration storage as long as six years. However, the viability and motility sperm thawed storage in liquid nitrogen during six years was lower than storage on the 1 and 2 years.
