Bibliography: leaves 267-292. This study aimed at finding better ways of storing ram semen at refrigerator or room temperature with particular reference to ingredients readily available in Indonesia, namely coconut extract and quail egg yolk. Coconut extract showed consistent advantages with regard to sperm motility and quail egg yolk was as effective as hen egg yolk. Investigations were extended to examine storage for subnormal semen such as would be produced during periods of heat stress. Motility was assessed visually and using a Hamilton Thorn semen evaluation apparatus.

Sperm survival in frozen semen appears to be determined largely by the amount of intracellular enzymes during freezing and thawing. Data is presented to show the effects of different diluents, temperature and glycerol as well as egg yolk concentrations, on glutamic-oxaloacetic-transaminase release.
