Abstract

Paired tests weight of twelve adult Large White boars (x = 18.5months)ranged from 424.90g to 705.90g while volumen percent of round spermatid nuclei in the testes was 3.63 ± 0.16. Mean daily sperm production and daily sperm production per gram testicular parenchyma were respectively 19.47 ± 0.78 x 109 and 33.47 ± 1.29 x 106 . In the second study the sorbitol dehydrogenase activity per gram deproteinised testicular parenchyma was negatively and not significantly correlated (r = 0.2)with the daily sperm produced per gram testis parenchyma
