Overview

Economic losses related to fertility disorders in breeding swine remain one of the main challenges faced by current industrial pig production systems. The present study aimed to evaluate plasma concentrations of progesterone, cortisol, and estradiol, morphometry, and occurrences of changes in the female reproductive system. Blood was collected from 114 female pigs during bleeding, and the female genital tract was removed for study. Progesterone, estradiol, and cortisol influenced the age groups of animals between 6 and 12 months and 37 and 60 months for plasma progesterone concentrations and animals between 24 and 36 months for plasma cortisol concentrations. Regarding cortisol, the most significant correlations were negative (the higher the cortisol concentration, the smaller the reproductive tract dimensions), which may be related to management and pre-slaughter stress. Changes such as salpingitis, uterine horn agenesis, eosinophilic metritis, endothelial cysts, and focal areas of fibrosis were also identified. One of the most common changes in the ovaries of sows was ovarian cysts.
