Reproductive seasonality limits the periods of breeding on the year and, therefore, productive output. However, some breeds appear as probably non-seasonal. The aim of the study was to characterize the seasonal pattern of Santa Inês rams, including an ultrasound characterization of the reproductive tract, testosterone concentrations, and semen characteristics.

- Resynchronization protocols have been shown to effectively reduce unproductive time in female livestock, including goats, without negatively impacting their fertility.
- In a study involving 38 multiparous Saanen goats, researchers tested a new progestogen device alongside eCG treatment to evaluate follicular growth, ovulation, and pregnancy rates.
- The results indicated that goats receiving eCG showed higher estrus manifestation and pregnancy rates, suggesting that these resynchronization protocols could be beneficial for dairy goat breeding.
