The newest generation TN Tempo boars are more robust than ever before. Recent independent trials showed a staggering $9 higher margin per pig placed in advantage of TN Tempo compared with one of the leading boars in the US, after a challenge with a multitude of diseases, including PRRS. Also in conventional health conditions, TN Tempo has proven to be more profitable (up to $2.6 higher margin per pig placed) than a leading US terminal boar. “Powered by Delta Canada” refers to Topigs Norsvin’s new research facility in Canada where TN Tempo boars are tested. Delta Canada is equipped with a unique, state-of-the art CT scanner that makes it possible to improve carcass composition, robustness, and meat quality faster and with greater accuracy. Delta Canada will substantially increase the genetic progress in TN Tempo.
In TN Tempo the Combined Crossbred and Purebred Selection (CCPS) program sets us apart from competitors. Massive amounts of data have been collected from both purebred and crossbred animals in health challenged production environments. The program has started already in the nineties. We were the first to start with this kind of testing. As a result, the genetic potential for survival also under health challenged conditions has considerably gone up. The selection program for specific natural resistance against PRRS started in 2018 will come on top and will further increase the robustness of TN Tempo offspring.
Use of TN Tempo as a terminal boar has positive effects on the number of liveborn pigs. Many of our customers have experienced up to 0,5 liveborn pigs more after switching to TN Tempo. TN Tempo offspring pigs are visibly more uniform and vital in the farrowing house. Weaning weights are often reported to be higher than competitor boars. TN Tempo pigs are easy starters in the nursery. All of this contributes to easier management and higher survival rates from birth to market.

Carcass weights keep on increasing. Feed is the most important component in the cost of producing a pig. Therefore, feed efficiency all the way up to heavier market weights will remain the highest priority in the breeding goal of TN Tempo.

Robustness is another top priority breeding goal trait, due to increasing challenges that our customers experience with disease and animal welfare legislation.

Robustness traits in the breeding goal of TN Tempo include survival from birth to market, congenital defects, leg quality, and natural PRRS resistance.

Natural PRRS resistance is based on the WUR SNP genotype. Results of economic analyses indicate that producers can save between $3.09 – $11.10 per head for a pig with the favorable WUR genotype.
