Added value farmed fish species are fed with high energy aquafeed, supplemented with emulsifying additives with the aim of increasing fat digestibility. However, the role of liver condition in the lipid digestion process is often not well evaluated.
Digest Fast is much more than a conventional emulsifier and contributes positively to the profitability of aqua facilities thanks to the synergy and effectiveness of its components. Its botanical and emulsifying ingredients optimise health and functionality of the liver, as well as promote the emulsification process within feed, achieving better absorption by the enterocytes and the subsequent distribution in the tissues. Liver protection and lipids emulsification increase efficiency of the diet and improve production results.
The profile of fatty acids determines the digestibility of fat. Digest Fast is characterised by its effectiveness in improving the digestibility of saturated fractions of fatty acids in both animal and vegetable oils/fats. This makes Digest Fast an interesting tool for nutritionists who are seeking continuous improvement of their feed formulation costs.
In addition to the economic benefits achieved with the inclusion of Digest Fast, tests carried out in several investigation centres, with or without replacements of added oil, showed significant improvements in feed conversion ratio (FCR) and daily weight gain, shortening the production cycle and, thus, improving the profitability of aquaculture companies.
Zootechnical performance improvements will be greater the higher the energy of the feed. Therefore, fish species such as salmon, trout, gilthead sea bream, sea bass, meagre, turbot and sole will benefit from the inclusion of Digest Fast as they provide for that high demand in energy. Digest Fast allows for a partial replacement of oil and fat from the diet.
Digest Fast also returns very positive results when measuring the protein efficiency ratio (PER). The PER index shows the weight gain obtained, compared to the total amount of protein supplied with the diet in a determined period. The biosurfactant Digest Fast has shown significant improvements in the utilisation of protein within fish, resulting in higher feed efficiency and lower feeding cost. This opens an interesting opportunity to adjust not only raw materials, but also protein, in order to maintain an optimised protein and energy ratio without losing performance.
