Reproductive and Pregnancy Dynamics in Pigs: Physiology, Biochemistry, Endocrinology and Immunity | Chapter 9 | New Horizons of Science, Technology and Culture Vol. 6

 

Reproduction and pregnancy in pigs involve complex coordination of body temperature, metabolism, hormones, and immune tolerance. Understanding these changes is crucial for reproductive efficiency, maternal health, and fetal survival. This chapter summarises variations in key physiological parameters (rectal temperature, respiratory and pulse rates) across reproductive stages, outlines serum biochemical shifts during gestation, and highlights the roles of hormones like progesterone and oestrogen in supporting pregnancy. It also discusses the immunological environment, shaped by cytokines such as IL-10, IFN-γ, and IFN-β, which maintain uterine immune balance and allow fetal development. These interlinked systems work together to ensure reproductive success. The establishment of pregnancy is further secured by maternal recognition of pregnancy (MRP), involving the integrated actions of reproductive hormones and immune mediators that maintain corpus luteum function and promote a favourable uterine environment.
