Summary
Seven cows deficiently supplied with β-carotene were used in an experiment in which 3 animals were given 500 mg synthetic β-carotene daily for two months, while the other 4 cows served as unsupplemented controls. The cows were synchronized with a double injection of PGF2α (30 mg, Enzaprost). At the peak of the second luteal phase the animals were killed.
β-carotene and progesterone analyses were carried out from blood samples and corpora lutea. The in vitro progesterone…

Positive correlation between the serum concentrations of β-carotene at insemination and at day 7 of the luteal phase and the concentrations of progesterone and the conception rate lead to a conclusion that periovulatory β- carotene and and vitamin A supplementation could improve follicular growth and development of the corpora lutea in cows with fertility impairement.

In contrast to previous findings no differences in duration of standing oestrus, length of oestrous cycle, plasma progesterone and luteinizing hormone (LH) concentrations and interval between LH peak and ovulation were observed between the groups.

It is concluded that small lutesal cells may be the principal source of luteal progesterone production in the sheep, and LH, which stimulated a maximal 3-4-fold increase in progestersone production by small lUTEal cells, had no significant effect on production by large lute al cells.
