Reproduction represents a key point in the maintenance of the pig sector in terms of production and contributes to the establishment of high levels of swine health. Therefore, it is essential to provide valuable tools to veterinarians about the main challenges related to this topic in order to minimise the impact caused by the most important disorders/diseases at reproductive level. This handbook, written by a renowned specialist in this field, has been developed through a visual and practical approach, using numerous figures that illustrate the ovarian pathophysiology of the sow, and providing the suitable content to the veterinarians so as to tackle this matter successfully.

1. Reproductive cycle Reproductive system: parts and functions Gonads: ovaries Tubular part Copulatory part Mammary glands Hypothalamic-pituitary-ovarian axis and reproductive hormones Factors that influence reproduction External factors Internal factors Puberty Reproductive ability What are the characteristics of their reproductive cycle? Follicular dynamics Structures present in the ovary during the reproductive cycle Antral follicles Corpora lutea Corpora albicans Hormonal profile Follicular phase Control of oogenesis and folliculogenesis Endocrine control Chronology of folliculogenesis in mature sows Follicle recruitment: end of dioestrus or weaning in end of lactation period Follicle selection: pro-oestrus Follicle dominance: oestrus Importance of oestrogens: heat Practical application on the farm: how is ideal heat detection? What induces the preovulatory LH peak in the follicle? Duration of oestrus and time of ovulation Practical application on the farm: time of service/insemination Luteal phase Early dioestrus Late dioestrus/gestation Corpora lutea in the reproductive cycle and gestation Ovulation rate Importance of P4 Practical application on the farm: use of progestogens to synchronise heat in cycling sows Luteolysis Practical application on the farm: induction of luteolysis with PG 2. Anoestrus and reproductive seasonality Anoestrus and pseudoanoestrus Summer anoestrus Hormone levels How can a problem of anoestrus be diagnosed on a farm? Differentiation between anoestrus and pseudoanoestrus Ovarian ultrasound scan and P4 determination Postmortem study of the ovaries Heat induction with gonadotropins Prevention of anoestrus 3. Identification of diseased ovaries Reproductive consequences of abnormal ovarian function Congenital alterations Intersexuality Paraovarian cysts Acquired alterations Cystic ovarian degeneration Ovarian neoplasms 4.
