The reproductive system is a collection of organs that work together for the purpose of producing a new life The major organs of the reproductive system include the external genitalia and internal organs‚ including gonads that produce gamete‚ which is a cell that fuses with another cell during conception in organisms that reproduce sexually. Substances such as fluids‚ hormones‚ and pheromones are also important to the effective functioning of the reproductive

Introduction Reproductive success is measured primarily by pigs produced per sow per year and is dependent upon both far rowing rate and litter size. In order to achieve optimal reproductive rates‚ both the anatomical and physiological workings of the reproductive system must function properly. A basic understanding of the anatomical and physiological function of the female pig reproductive system can aid producers in anticipating and troubleshooting reproductive problems‚ and in facilitating decisions
