ARTICLE 92 FEED & ADDITIVE MAGAZINE November 2025 quently, these variations in performance potential imply strong variability in nutritional requirements, highlighting the need to adapt nutritional recommendations according to genetics. The feeding program also had a clear independent effect: the high-lysine program yielded +175 g/day higher ADG and -0.35 points lower FCR compared with the low-lysine program. However, reducing lysine levels lowered feed costs by €11 per pig through a €35/ton cheaper diet but resulted in a €24/pig loss in feed margin. These findings show that cutting investment in feed does not improve competitiveness but only reduces overall feed cost due to negative impacts on performance and margin. MAXIMIZE MARGIN WITH OPTIMAL FEEDING STRATEGIES Identifying the best techno-economic strategy based on the animal’s genetic potential is essential to maximize feed margin. To this end, Techna has developed digital solutions such as the Wefeed platform, composed of three modules: • Wefeed Check – analyzes improvement levers on the farm. • Wefeed Nutri – optimizes feeding strategies for finisher pigs. • Wefeed Carcass – maximizes farmer income by optimizing slaughter strategy. Wefeed Nutri predicts pig performance at the individual level based on feeding strategy (feed composition and feeding program) and the techno-economic context (pig price, feed cost), allowing identification of the optimal feeding strategy. Techna also invests in on-farm data collection and analysis through its joint-venture Kumulus. The objective is to refine performance prediction equations and promote dynamic, real-time data use. Pilot farms are equipped with precision-feeding systems that monitor consumption and growth while enabling individualized daily feed distribution. Performance data analysis allows prediction of pigs’ daily nutritional needs to fine-tune feeding and avoid both deficiencies and excesses. Techna has quantified the benefits of precision feeding: compared with a two-phase strategy, it increased feed margin by 8% and reduced nitrogen excretion by 23%. REDUCE AGGRESSIVE BEHAVIOR In modern production systems, pigs are exposed to multiple stress factors such as heat, stocking density, competition for feed or water, and transport.
