The following paper is investigating the different influencing factors throughout a female pig’s life. The topics mainly focus on the reproductive aspects. Starting with the physiology and anatomy of the sow’s reproductive tract. The mechanisms of the oestrus cycle with all it’s challenges and practical points that ensure a healthy and fertile herd. Especially the farm’s management and continuous controlling of feedstuff, semen and stable hygiene are from great importance. One of the biggest errors of keeping breeding sows are the returns to oestrus resulting on the one hand in economic losses and on the other hand in a poor life quality of the sow. Raising a healthy breeding pig requires a balance between animal welfare, a professional farm management and veterinary expertise.
