Topigs Norsvin’s philosophy emphasizes the importance of robust and strong pigs. This belief is reflected in the Early Phase Vitality of their TN Duroc offspring. The high pre-wean survivability demonstrates their strong start and translates to high performance in the finishing phase.
In the TN Duroc nucleus population, every piglet is weighed. Although this task is substantial, it is invaluable and serves as a key component of the renowned piglet vitality protocol. Since 2001, Topigs Norsvin annually weighs hundreds of thousands of piglets from its pure lines.
Sophisticated Breeding Means Less Labour Required
The Topigs Norsvin breeding program ensures the production of strong, robust piglets. These pigs are born with better-developed organs, such as the gastrointestinal tract, and have greater energy reserves, including higher glycogen levels in the blood and liver.
Newborn TN Duroc piglets are vigorous and energetic and actively seek for and consume colostrum and milk. Their innate robustness reduces the likelihood of health challenges, requiring less input and resources from farm staff. These pigs are self-sufficient and do not require intensive care.
Farm Trials Show High Survival Rates
When compared to other Duroc lines, the TN Duroc pre-weaning survival rate is higher; recent study results indicate that the TN Duroc pre-wean survival rates are 2.3 to 5.9 percentage points higher.

TN Duroc offspring pre-wean survival rates are 2.3 to 5.9 percentage points higher compared to other TN Duroc lines.
In addition to greater survivability, there is an improvement in weaning weights associated with the TN Duroc. A recent study demonstrated that TN Duroc offspring have an average weight of 6.2 kg, approximately 0.2 kg greater than the average weaning weight of another Duroc line (6.0 kg). Higher weaning weights contribute to enhanced performance during the nursery and finisher phases.
Summary
TN Duroc piglets are known for their exceptional pre-weaning survival rates, a result of Topigs Norsvin’s breeding program. This not only results in more piglets weaned but leads to minimal assistance required in the farrowing phase, reducing the overall workload. Furthermore, their strong start sets the foundation for a highly productive nursery and finishing phase with fewer challenges.
