    Norsvin Landrace, one of the component lines of TN70, plays an important role in this.
    The non-traditional development of this line has been essential for what it is today. In contrast to other commercial maternal lines, this breed has a long history of selection for finishing efficiency in the 1960s, 70s and 80s. It wasn’t until the 1990s that breeding goals changed more in the direction of maternal productivity. Based on US powerhouse customer feedback, no other maternal breed provides more pigs and heavier weaning weights, with such an enormous contribution to its offspring’s feed efficiency, lean growth potential and carcass quality.

    Compared to other sows on the market, TN70 grows faster, reaches puberty at heavier weights, is mated leaner and has less body reserves during her lifetime production cycle. Therefore, more focus is needed on maintaining body fat and weight during the reproductive cycle and to minimize fat and weight fluctuations. To minimize lactation condition losses, nutrient intake during lactation needs to be maximized. Diets should be balanced so that all nutrients are provided in the correct proportions for nutritional requirements and energy balance. Our Technical Service department have developed an online tool for our customers that offers the possibility to make a comparison between the average sow herd condition and the recommendations for sow condition by Topigs Norsvin. The Topigs Norsvin Feed Tool is available at:

    The excellent mothering abilities of TN70 allow you to produce more output per farrowing pen with less labor. Many functional teats reduce the need for cross fostering, which saves labor time and farrowing space for productive sows.
    Heavy birth weights and high milk production boost piglet growth. Heavier piglets at weaning makes the transition to the nursery much easier with less health issues.
    Finally, you’re offering a more valuable product to the finisher producer, considering the high genetic potential of TN70 pigs for finisher efficiency and lean growth

    In the breeding program of TN70, our focus is both on improving quantity and quality. With increasing numbers of piglets born, we make sure that litter uniformity and piglet survival will never be compromised. The same goes for sow longevity. These type of traits will receive even more emphasis towards the future.
    Sow behavior is another area that will receive more and more attention. Improved animal welfare on farms will require sows that are able to produce optimally under these conditions. We anticipate on this on our nucleus farms, that have loose housing, pen farrowing, and no tail docking.
