Dietary energy (DE) is critical for maximizing protein retention and has previously been shown to have the biggest impact on feed conversion rates. Sufficient dietary lipid energy is needed to ensure protein is retained as growth and not catabolized for energy itself. However, excess energy from lipid results in high tissues lipid deposits and reduced fillet yields. Leaner growth may give a positive signal to appetite and the increased feed intake will increase the growth more than just a reduction in FCR alone. Micronutrients are cofactors for almost all the biological pathways influencing how the macro nutrients are utilised. This project we will investigate how the micronutrient profile affects the feeds performance at different macronutrient levels. The purpose of the project is to develop more sustainable feeds, minimizing nutrient excretion and maximizing their retention efficiency, growth and FCR with a better slaughter/fillet yield.
