Seminal plasma contain several biochemical constituents, estimation of which was considered to indicate functional activity of epididymis and accessory glands. Conditions like occlusion of excurrent duct (Gassner and Hopwood, 1953) and functional derangement of accessory glands (Doichevd et al., 1978) were observed to alter the fructose, citric acid, free amino acid, Carnitine and Glyceryl phosphoryl choline levels in seminal plasma (Carter et al. 1981). Bora et al {1982) have correlated the different microsocopical and biochemical characteristics of semen in normal bulls Similar comparative study in cross bred bulls was carried out and the results are presented in this paper.EnglishVeterinary ScienceArticle
