Abstract

The camel is known to be a seasonal breeder and, in the male camel, the breeding activity maximizes during the rutting period (winter and spring seasons). During the non-rutting period (summer and autumn), however, the breeding activity almost ceases completely. Serum steroid hormonal, electrolytes and trace element profiles were studied in 16 adult male camels aged 5-9 years, slaughtered during the rutting (n=8) and non-rutting periods (n=8). Moreover, testicular and epididymal tissue contents of electrolytes and trace elements were also studied during these two periods. Serum levels of testosterone, progesterone and T(4):T(3) ratio were higher in the rutting animals when compared to the non-rutting ones, while the reverse was true for serum T(3), T(4) and corticosterone levels (p<0.01). Among minerals, serum levels of sodium, calcium, copper and zinc were higher, while those of potassium were lower, in the rutting than non-rutting camels. In the testicular tissue, the levels of sodium, calcium, copper and iron were higher in the rutting group, while magnesium was higher in non-rutting one. In the epididymis, the tissue levels of chloride, iron and zinc were higher in the rutting than non-rutting period. These results demonstrate a clear evidence of the distribution of steroid hormones, electrolytes and trace elements forming and maintaining a certain level at two different physiological states in camels.
