Feed based on egg powder and milk powder for freshwater shrimp.

Description

/ 3 Feed based on egg powder and milk powder for freshwater shrimp. Field of Invention

[001] The present invention relates to the formulation of a dry and dehydrated feed, developed for feeding freshwater shrimp, particularly Macrobrachium rosenbergii (Malaysian giant shrimp) and other freshwater shrimp species. The invention also involves the feed preparation process, which allows for obtaining a stable mixture with good durability and less demanding refrigeration requirements compared to conventional wet feeds. State of the Art

[002] Currently, the feeding of post-larvae of freshwater shrimp, especially of the genus Macrobrachium, is carried out using fresh ingredients for the production of wet feed. However, the use of fresh ingredients presents several challenges, such as the difficulty in obtaining ingredients of consistent quality, the high cost of refrigerated storage, and the perishability of the ingredients, which can compromise the nutrition of the larvae and the efficient production of shrimp.

[003] Furthermore, there are no effective commercial solutions on the market to meet the specific nutritional needs of freshwater shrimp larvae, especially with regard to inert and long-lasting feed. Detailed Description of the Invention

[004] The invention proposes a dehydrated feed formulation for freshwater shrimp composed of the following ingredients: • Whole egg powder (37.44%) • Milk powder (17.62%) • Fish meal (8.81%) Petition 870240111510, dated 12 / 31 / 2024, page 5 / 9 / 3 • Blood meal (8.81%) • Meat meal (8.81%) • Wheat flour (8.81%) • Mineral and vitamin premix (6.17%) • Fish oil (3.52%)

[005] These ingredients are selected to meet the nutritional needs of freshwater shrimp, promoting healthy growth during the larval stage. Preparation Process

[006] The preparation for the present invention is carried out as follows: 1. To prepare 500 g of feed, add 386.5 g of water to 113.5 g of the dry mix. 2. The mixture is left to stand for 10 minutes to hydrate. 3. After this period, the mixture is blended in a blender for 2 minutes. 4. The homogenized mixture is placed in a pudding mold (14 cm in diameter), suitable for a volume of 500 mL. 5. The pudding is cooked in a bain-marie at 95°C for 80 minutes. Cooking time may vary depending on the size of the mold used. 6. The final product will be a wet feed pudding weighing approximately 400 g, which can be partitioned as needed and stored in a regular freezer. Benefits of the Invention

[007] The present invention has the following advantages: • Greater stability in water, which makes the feed more efficient for aquatic organisms. • Greater durability due to the use of dehydrated ingredients, which have a longer shelf life and require less refrigeration. Petition 870240111510, dated 12 / 31 / 2024, page 6 / 9 / 3 • Ease of preparation and storage, allowing for large-scale production without the need to store fresh and perishable ingredients. • Versatility: The proposed feed can be used with different species of freshwater shrimp, such as Macrobrachium rosenbergii, Macrobrachium amazonicum, and Macrobrachium acanthurus, and is also suitable for use in larviculture laboratories. Potential Applications and Market

[008] The invention has great potential for use in the aquaculture industry, especially in freshwater shrimp larviculture systems, as it solves the problems faced by producers in feeding larvae with wet feed. The practicality and stability of the product are also advantages for companies involved in the manufacture of animal feed, seeking sustainable alternatives with a longer shelf life.

[009] The growing world production of freshwater shrimp, especially the giant Malaysian prawn (Macrobrachium rosenbergii), highlights the relevance of the invention, since Brazil, in particular, occupies a prominent position in the production and export of freshwater shrimp.

[010] Furthermore, the proposed innovation could meet an unmet market demand by providing efficient nutritional solutions for shrimp farming, a sector that has been experiencing increasing growth.

[011] The formulation and feed preparation process described in this patent offer an innovative and sustainable solution for feeding freshwater shrimp in larval rearing laboratories. The invention solves critical issues of stability and storage of fresh ingredients, while providing adequate nutrition for the healthy development of larvae. Furthermore, its use can be expanded to other species of freshwater shrimp, contributing to the advancement of shrimp farming in Brazil and worldwide.
