    The Sperm-Class Analyzer® detected four subpopulations of spermatozoa with different motility characteristics in the ejaculate of the Catalonian donkey. Significant differences (P < 0.001) in the distribution of these subpopulations, as well as in total sperm number and percentage total motility, were seen in the diluted semen of four sampled donkeys. All the ejaculates evaluated showed excellent semen quality characteristics; the sperm they contained was more rapid than horse sperm. Principal components analysis showed sperm l-lactate production to be a good predictor of semen condition. This, plus the characteristics of the motility patterns of the different sperm subpopulations, provides an excellent overall indicator of semen quality. © 2004 Elsevier Inc. All rights reserved.
