Abstract
Turkey semen storage in vitro for 24 h at 10.degree. C was not noticeably improved by using a buffered diluent compared with an unbuffered (pH 7.3) diluent. This is different from the case of the fowl and probably reflects differences in the metabolism of spermatozoa betweeen the species. Adverse effects on the fertilizing ability of turkey spermatozoa were observed with diluents buffered around pH 7.4 and 5.8 when compared with the use of diluent either buffered at pH 7.1 or unbuffered.
