ARTICLE FEED & ADDITIVE MAGAZINE September 2022 51 About Luigi Moreira Luigi Moreira received his D.V.M.Z degree in Veterinary medicine from University of Cuenca, Ecuador in 1994. Moreira started his career as a Technical Assistant at Hoffman La Roche. After 5 years he accepted a role as a Technical & Commercial Manager at DSM. Within DSM Moreira held various positions across Latin America. From 2006 to 2009 he was Director ANH Centro America & Caribbean, DSM in Costa Rica. Then be moved back to Ecuador as a Regional Tropical Aquaculture Manager LATAM. Last position he held within DSM was Director ANH Andean Countries in Colombia. In 2015 Moreira joined Trouw Nutrition as an Area Manager LATAM Trouw Nutrition in Ecuador. Since 2020 he is Trace Mineral Programme Manager for Selko Feed Additives based in Mexico. was greater for pigs fed control diets (no source of copper added) compared to diets containing 150 ppm copper. However, when given a choice between copper sources, feed intake was greater for diets containing IntelliBond C vs copper sulfate (Figure 3). Mitigating the reduction of feed intake can reduce the impaired response on performance during heat stress. Increasing dietary fat can also influence an animal’s performance during heat stress. This feeding practice reduces internal metabolic heat, increases energy density, reduces dust, and improves palatability. Adding 150 ppm of IntelliBond C to the diet improved ADG and G:F of pigs and increased mRNA abundance of genes involved in uptake, transport and oxidation of fatty acids (Espinosa 2019). This improved efficiency of fatty acid utilization allowed more energy generated to be used for maintenance and growth of pigs. As global temperatures continue to increase year after year, so do economic losses due to heat stress. Providing proper nutrients to support and sustain pigs’ performance is an important part of helping pigs manage heat stress and the harm it can inflict on animal performance and producers’ businesses. The data presented here indicates that the use of IntelliBond minerals during times of stress can improve pig resilience, ensuring performance is sustained and the economic impact of stress is lowered.
