Summary
Sow fertility issues often stem from ovarian dysfunction, including cysts, impacting reproductive success. Understanding these ovarian aberrations is key to improving sow productivity and reducing culling.
Area of Science:
- Reproductive endocrinology
- Veterinary gynecology
- Swine reproduction
Context:
- Sow reproductive performance is critical for the swine industry.
- Fertility problems are a primary reason for sow culling.
- Ovarian dysfunction significantly impacts sow productivity.
Purpose:
- To discuss the endocrinological and neuroendocrinological factors affecting sow ovarian function.
- To review common ovarian abnormalities in sows, such as cysts and follicular atresia.
- To present recent research findings on the etiology of ovarian cysts in sows.
Summary:
- Sow slaughter is often linked to fertility issues, primarily caused by ovarian dysfunction rather than uterine problems.
- Complex endocrinological and neuroendocrinological events regulate sow ovarian physiology; disruptions lead to abnormal patterns.
- Common findings include atretic follicles, abnormal follicle maturation, ovarian cysts (especially in older sows), and low ovulation rates.
Impact:
- Provides insights into the causes of ovarian cysts and other reproductive disturbances in sows.
- Contributes to understanding the etiology of ovarian cysts, aiding in potential management strategies.
- Highlights the importance of addressing ovarian function for improving sow fertility and reducing economic losses in swine farming.
