dc.description.abstractThis study was carried out to detect the relationships between levels of vitamin C in plasma, corpus luteum, follicular fluid and those of progesterone and oestradiol 17 beta in Holstein cows getting through different periods of sexual cycle, presented at slaughterhouse. Prior to slaughter, blood samples from each cow were collected. After slaughter, ovaries of animals were taken then, the stage of sexual cycle was determined post-mortem. Diameters of corpora lutea and follicles were determined by ultrasonography. Follicular fluids were aspirated while corpora lutea were incised and weighted. The progesterone and oestradiol 17 beta concentrations were determined by EIA method. Levels of vitamin C were determined by spectrophotometer. Vitamin C concentrations in the corpus luteum were correlated with weights/diameters of corpora lutea as well as plasma progesterone levels. In addition, there was also a positive correlation between plasma vitamin C levels and diameter of the corpus luteum. Furthermore, a positive correlation was also evidenced between plasma progesterone levels and diameter/weight of corpora lutea. Oestradiol 17 beta levels in follicle fluids increase in parallel with an increase in follicle diameter. On the contrary, small follicles, irrespective of stage of oestrus cycle had, significantly higher vitamin C content than large follicles. In conclusion, it may be speculated that vitamin C might be used in the synthesis of collagen during formation of the corpus luteum, consumed in increased quantities while oestradiol 17 beta biosynthesis occurred.en_US
