The present invention relates to a composition for aquatic animals comprising as active ingredient 25-hydroxyvitamin D, preferably 25-hydroxy vitamin D3 (25-OH D3). The present invention further relates to the use of 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), as feed additive for aquatic animals including fish and shrimp. More particular, this invention relates to the use of 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), for improving feed utilization and growth and performance parameters of the animals, such as the feed conversion ratio (FOR). Immunity, protein efficiency ratio (PER), specific growth rate (SGR), final body weight, feed efficiency (FE), nutrient utilization, body protein content, and/or carcass yield and/or for increasing levels of Vitamin D, preferably Vitamin D3, in the blood of aquatic animals.
A composition comprising as an active ingredient 25-hydroxyvitamin D, wherein the composition is intended for intake by aquatic animals and wherein and the concentration of the active ingredient in the final feed added to the animal is in the range from 50 μg to 1500 μg per kg feed, preferably 100 μg to 1500 μg per kg feed, preferably 150 μg to 1500 μg per kg feed, more preferably 150 μg to 1250 μg per kg feed, more preferably 150 μg to 1000 μg per kg feed.
A method of providing an extruded feed pellet comprising as an active ingredient 25-hydroxyvitamin D, said method comprising the steps of:
Use of 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), for improving the feed conversion ratio (FCR), Immunity, feed efficiency (FE) protein efficiency ratio (PER) and/or the growth performance (nutrient utilization, body protein content, protein efficiency ratio (PER) and/or the growth performance (specific growth rate SGR, Final body weight and/or carcass yields) in aquatic animals said use comprises feeding to the aquatic animal a feed comprising 25-hydroxyvitamin D (“25-OH D3” and/or “25-OH D2”).
Use of 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), for increasing levels of Vitamin D, preferably Vitamin D3, in the blood of aquatic animals said use comprises feeding to the aquatic animal a feed comprising 25-hydroxyvitamin D (“25-OH D3” and/or “25-OH D2”) and Vitamin D3.
A composition comprising 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), for use in improving the feed conversion ratio (FCR), Immunity, feed efficiency (FE) protein efficiency ratio (PER) and/or the growth performance (nutrient utilization, body protein content, protein efficiency ratio (PER) and/or the growth performance (specific growth rate SGR, Final body weight and/or carcass yields) in aquatic animals.
A composition comprising 25-hydroxyvitamin D, preferably 25-hydroxyvitamin D3 (25-OH D3), for use in increasing levels of Vitamin D, preferably Vitamin D3, in the blood of aquatic animals.
