The results obtained are as follows. 1. The optimum pH was 7.2 to 7.5 for sperm respiration, and 7.0 to 7.2 for sperm motility. 2. Sperm concentrations ranging from 0.5 to 4.0x108 per ml of sperm suspension gave no effect on the respiration. 3. To study the effect of an exogenous substrate on the respiration of goat spermatozoa, it is necessary to wash the ejaculated sperm sample twice at least. 4. The optimum concentration of exogeneous substrate was 10-2 to 5x10-2 M for metabolic studies of goat spermatozoa. Table 1. Composition of buffered diluents; Table 2.
