BARRIOS HERNANDEZ, Dursun  e  DUQUE MUNOZ, Leonardo. Economic cost of follicular cysts in postpartum dairy cows. Rev Colom Cienc Pecua [online]. 2012, vol.25, n.2, pp.252-257. ISSN 0120-0690.

Follicular cysts represent a common reproductive pathology in dairy cows. Prevention and early detection are crucial to prevent economic loses from medical treatments and decreased milk production. Objective: to evaluate the economic loses attributed to follicular cysts on post-partum dairy cows. Methods: Medical treatments and milk production records were retrieved from a total of 950 cows at five different herds in the high plains of Antioquia. Usual treatment consisted of 1-3 doses of GnRH and PGF2 . A sensitivity analysis was conducted to assess the cost per liter of milk produced depending on the response to treatment. Results and conclusion: The mean cost of milk production was 496 Colombian pesos/liter for cows free of cysts. This value increased 3.5, 13.3 and 33.8% for cystic cows that received one, two, or three hormonal treatments, respectively. Consequently, any measures aimed at reducing the incidence and rapid resolution of follicular cyst will result in substantial financial gains to the producer.
