NEWS FEED & ADDITIVE MAGAZINE August 2024 23 RaboResearch recently publicized its new report on aquaculture. According to the report, the global aquaculture industry is experiencing positive trends as demand for salmon and shrimp begins to improve in the second half of 2024. Despite ongoing biological challenges in farming these species, the industry is supported by the recovery of Western economies. Feed costs are anticipated to decrease, thanks to a rebound in fish meal supply, providing a silver lining for the sector. According to Gorjan Nikolik, Senior Global Seafood Specialist for RaboResearch, the salmon market continues to face a tight supply, with prices expected to remain high through the latter half of 2024. Seasonal patterns will influence pricing, but the overall trend suggests that costs will stay above average. Norway and Scotland are poised for a supply recovery, although this remains tentative due to unresolved biological issues. The US and Asia are experiencing depressed demand, which has not allowed prices to offset the high costs resulting from weak biological performance. However, the anticipated reduction in feed costs should offer some relief to producers.

This format blended a two-day live event and online presentations, with on-stage discussions following a total of 12 hours of streamed pre-recorded videos. Major themes in 2024 were factors affecting immunity, led by Dr. Megan Edwards, Nutritionist at Integral Nutrition in Singapore, and piglet health through nutrition, led by Dr. Theerawit Poeikhampha, Assistant Professor at Kasetsart University in Thailand. The interest of the concept of ABC-4 (Acid Binding Capacity) value has been highlighted in different technical presentations. Gilles Langeoire, Pig Nutrition consultant in France, reviewed the nutritional risks from pharmacological levels of zinc oxide: "This 'false friend' limits the efficacy of phytase, reduces digestible phosphorous and calcium, and has the highest acid-neutralizing effect of all feed ingredients." Langeoire gave the example of Danish studies which showed that by manipulating feed formula, it is possible to get rid of medicinal dose of zinc oxide in diets for light piglets. Dr. Mike Tokach, Professor/Extension Specialist at Kansas State University in USA explained the importance of considering ABC-4 values in formulating nursery diets. Dr. Tokach pointed out that by lowering ABC-4 values to 200-250 meq/kg in phase 1 and to 250-300 meq/kg in phase 2 piglet feeds without pharmacological ZnO, positive effects on growth performance and fecal score were measured. According to the information shared during the event, in the combination of solutions that are available to get rid of excess ZnO, the use of potentiated zinc oxide (HiZox®, Animine) supports digestive health of weaned piglets. An experiment supervised by Kansas State University was carried out with four treatments in two phases: a positive control (3000/2000 mg/kg), HiZox® low (150/150 mg/kg), HiZox® medium (500-300 mg/kg), HiZox® high (800-500 mg/ kg). Feed intake and body weight gain improved as HiZox® increased (p< 0.05, quadratic).
