This signaling acts on both the endometrium and luteal tissue to prevent the regression of the CL by activation of genes that are responsible for CL maintenance. During mid to late pregnancy, the CL relies primarily on luteinizing hormone for maintenance till parturition. Animal nutrition is essential prior to copy and through gestation to make sure optimum reproductive performance is achieved. Female pigs attain sexual maturity at 3–12 months of age, and are available into estrus each 18–24 days if they are not successfully bred.
