  • This slide briefly gives a recap of Prof Maes' findings. With regard to group housing, he mentioned that sows have a good social memory - which would lead to a conclusion of them preferring stable groups.

  • She explained the role of Luteinising Hormones (LH) and Follicle Stimulating Hormones (FSH) during follicle evolution, ovulation and the weaning-to-oestrus interval. One of the key messages is that the next oestrus already begins in later stages of lactation.

  • He said sows secrete melatonin as a consequence of a change in daylight, which influences FH and LSH release - and thus influence reproduction figures.

  • Closing off, Dr Torsten Pabst, a veterinarian from Germany discussed the state of pig production in Germany and introduced how his practice is working - for instance by making video recordings of the insemination process.

  • Dr Pabst had also done several trials with the product Fertipig (by Ceva Santé Animale) and he concluded using 5 ml after weaning reduced the weaning to oestrus interval, increased insemination rates and more piglets are born per 100 weaned sows.

  • He presented several week systems, varying from one week to five weeks - and with weaning at 21 days or 28 days. When planning and organising well, they offer a range of opportunities for a higher profitability.
