Description Forty cows with ovarian cyst were studied for type of cysts, clinical findings and evaluation the hormonal profiles (Progesterone and cortisol) and appropriate therapy for ovarian cysts in dairy cows and pregnancy rates after treatment. Cows were randomly treated with either IM injection of GnRH (Group 1), oral feeding (10gm daily for 5 days) of potassium iodide (Group 2), a combination of GnRH + KI (Group 3), or Ovsynch protocol (GnRH day 0, PG day 7 and GnRH day 9). Evaluation of type and location of ovarian cysts revealed 85% of follicular type cyst and 15% of luteal type cysts present on right ovary. The highest incidence (50.75%) of ovarian cysts was recorded in cows with age greater than 4 years. In relation to breed, ovarian cysts were common among HF cows (80%) than the non-descript cows (20%). Progesterone profiles before and after treatment revealed that treatment 4 (group 4) and treatment 1 (group 1) resulted in significantly higher (P≤0.01) plasma progesterone compared to control and other treatments however plasma cortisol values revealed non-significant differences. The overall pregnancy rates in treatment group 1 (GnRH), group 2 (KI), group 3 (GnRH + potassium iodide) and group 4 (Ovsynch protocol) were 40%, 0%, 60% and 40% respectively. It was concluded that unilateral follicular ovarian cysts are common in HF cows above third parity. Cows with ovarian cysts frequently evidence nymphomania, prolonged estrus, anestrus, mucometra as clinical signs in combination. Cows with luteal cysts have high plasma progesterone
(>1 ng/ml). and GnRH + potassium iodide is the most appropriate therapy for cows with ovarian cysts.
