Analytical method
( 1 )
—
For the quantification of glycosylated 1,25-dihydroxycholecalciferol in the feed additive and in the complementary feed (bolus):
—
Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS).
Dairy cows
—
—
0,004
1.
The additive shall be only used for incorporation in a complementary feed (in the form of a bolus) to reduce the risk of milk fever and subclinical hypocalcaemia.
2.
The use of the additive shall be allowed only once during the pre-parturient period (from 9 days before calving to immediately before calving).
3.
The additive shall be orally administered once in the form of a bolus, with daily administration of:
—
a minimum of calcium of 60 g per cow during one week before calving and 84 g per cow until the end of the third week of lactation,
—
a minimum of magnesium of 18 g per cow during one week before calving and 26 g per cow until the end of the third week of lactation.
4.
The directions for use of the additive shall indicate the storage conditions.
5.
Maximum content of the combination of glycosylated 1,25-dihydroxycholecalciferol with vitamin D 3 (cholecalciferol) per kg of complete feed: 0,1 mg ( 2 ) of cholecalciferol.
6.
Simultaneous use of the additive with 25-hydroxycholecalciferol shall not be permitted.
7.
For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address the potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal breathing and skin protective equipment.
