Litopenaeus vannamei shrimp

Whiteley shrimp (L. Vanammei) benefits from the consumption of natural Astaxanthin from Haematococcus pluvialis. Health, reproduction, and survival parameters are all improved. Microalgal
Astaxanthin also provides a significantly better pigmentation with
lower inclusion rates as compared to synthetic or bio-synthetic sources.

Broodstock fed with 40 g of Red Meal per kg of feed showed:

- Very good Astaxanthin absorption seen as black color

This is due to the high affinity between (3S, 3’S) natural Astaxanthin and tissue proteins. The enantioselectivity of chiral Astaxanthin molecules allows proper binding to chiral crustacyanin proteins.


- No wounds after clash
Thanks to an active immune system, robust, in-condition hemocytes
swiftly activate proPO to produce melanin synthesis involved in wound healing and enzymes of the clotting system.


- Improved health, active mating, better egg quality, and quantity
Explained by the Astaxanthin antioxidant effect that protects cell and mitochondria membranes.

Larvae and Post-Larvae fed with Red Meal-enriched microalgae, rotifer, artemia, or pellet developed:


- Vigorous PL 12 with lipids in large dark hepatopancreas and excellent positive rheotaxis
Astaxanthin antioxidant action quenches free radicals protecting mitochondria and cell membranes from oxidative stress produced by
high energy needs for rapid body differentiation and molting during
metamorphosis.

Nursery PL12 to PL37 fed with 3-5g of Red Meal per kg of feed exhibited:


- Noticeable stress resistance to low salinity, molting, and diseases, with over 90% survival rate at PL 37
Again, the active immune system is ready to work. Strong and healthy hemocytes are produced abundantly by very well guarded hematopoietic tissue cells. Astaxanthin is linked and coupled to phospholipids in the cell and mitochondria membranes, quenching the ROS/RNS that produce oxidative stress and lipid peroxidation, preventing membrane destruction.

Growing stage shrimps fed with 3-5g of Red Meal per kg of feed during the last 15 days before harvest achieved:
- 27+ color on salmon fan
The final red color after the bathochromic shift from a dark color during dehydration in cooking largely depends on the isomerism of Astaxanthin. The (3S, 3’S) enantiomer of H. pluvialis plays a relevant role in pigmentation.

Laying hens

huevo.tif

A full battery of tests was carried out on 100 Hy-Line laying hens under a free-range regimen. An inclusion of 8 ppm of Red Meal in the hen’s feed reported the following improvements:


- Even coloring of the egg yolks along the entire laying line.


- Color reaches 13 (20%) to 14 (80%) in the color fan


- Productive life increased 10 to 20%


- Decreased mortality rate to 0% until 100 weeks.


- Improved general health including better resistance to thermal stress.


- Laying rate increased up to 2%
