Effects of holding temperature and time on acrosomal abnormalities of fowl sperms

Abstract

Experiments were conducted on New Hampshire males to determine the effects of holding temperature and time on
abnormalities of acrosomal and cap sperm head. At 5 and 15°C, the per cent acrosomal cap abnormalities and abnormal
sperm head were lower than that of 25 and 41°C. But no significant difference was observed between 5 and 15°C. The
most efficient holding temperature was 5°C,!Acrosomal abnormalities were storage time dependent and increased with
the increase in time of storage. These traits of chicken semen stored at 5°C for 3 and 6hr were significantly lower than that
of 18 and 24hr. Both of these traits did not differ significantly at 5°C storage for 3 and 6hr, though remained lowest after
3hr or storage at 5°C.
