Ovarian diseases contribute significantly to infertility in dairy cows, accounting for about one-third of all cases. These conditions are typically characterized by follicular cysts, ovarian quiescence, persistent corpora lutea, delayed ovulation, and anovulation. Proper diagnosis and treatment are essential for improving reproductive performance. For follicular cysts, a common treatment approach includes intramuscular injections of progesterone at 50–100 mg, or luteinizing hormone (LH) at 100–200 units per dose, administered every other day for 2–3 sessions. Alternatively, human chorionic gonadotropin (HCG) can be given at 10,000 units daily for 2–3 days. These treatments help stimulate ovulation and resolve the cysts effectively. In cases of ovarian quiescence or persistent corpus luteum, uterine thermal baths with 45°C saline solution may be used. Ovarian massage is also beneficial. Additionally, oral potassium iodide (KI) at 5 grams per day for seven days can support hormonal balance. During days 5–7 of the treatment, HCG at 5,000 IU is injected intravenously, along with an intramuscular injection of cloprostenol at 0.4 mg. After estrus, a second course of KI may be recommended to enhance recovery. For delayed ovulation or anovulation, it is advisable to administer either luteinizing hormone-releasing hormone (LRH-A3) at 0.2–0.3 mg or HCG at 1,000–2,000 IU within 8 hours before or at the time of artificial insemination. This helps trigger ovulation and improves fertility outcomes. Uterine diseases, which make up approximately two-thirds of infertility cases in dairy cows, are often caused by endometritis and uterine accumulations. Treatment primarily involves uterine infusions. In mild cases, a solution of 30–35°C 5% glucose or normal saline (100 ml) combined with 1.6 million units of penicillin and 2 million units of streptomycin is injected into the uterus. The timing should be either before or 6–8 hours after insemination. For more severe cases, solutions such as 0.2% su children, 0.1% potassium permanganate, 0.02% nitrofurazone, or 0.02% benzalkonium bromide at 38–40°C (100–150 ml) may be used. Commercial products like Gong Dekang have also shown good results in treating uterine infections. Preventive measures are crucial. Farmers should focus on proper feeding and management, reducing excessive concentrate feed to prevent obesity, and promptly treating any obstetric issues. Artificial insemination must be performed under strict hygiene conditions, with proper disinfection to avoid secondary infections. Maintaining clean environments and preventing fecal contamination of the cow's body is also important to reduce disease risk.
