Panbonis® is a complementary feed that contains a standardized level of 1,25 dihydroxycholecalciferol-glycosides (1,25(OH)2D3-gly) from dried and ground Solanum glaucophyllum leaves.
1,25(OH)2D3-gly can only be absorbed after the sugar molecule is released from 1,25(OH)2D3 by specific enzymes that are present in the intestine. This gradual process ensures a slow release of the bioactive component. Once absorbed, it does not need additional activation steps like vitamin D3 or 25-hydroxycholecalciferol (25(OH)D3) do, which means that Panbonis® can directly support the animal even when specific activation enzymes in liver and kidney are limited.

Vitamin D3 (metabolites) in animal feed
The following three vitamin D3 metabolites can be used to supplement animal feed:
-
Vitamin D3- the most common source
-
25-hydroxycholecalciferol (25(OH)D3)- either produced in a chemical process or through fermentation
-
1,25-dihydroxycholecalciferol-glycosides (1,25(OH)2D3-gly)- an entirely natural source of the bioactive form of vitamin D3
Some characteristics of the vitamin D3 and its metabolites, as used in animal nutrition, are summarised in Table 1.
Vitamin D3 | 25(OH)D3 | Panbonis® | |
---|---|---|---|
Principal molecule | Vitamin D3 | 25(OH)D3 | 1,25(OH)2D3-gly |
Solubility | Fat-soluble | Fat-soluble | Water-soluble |
Enzymatic activation steps | 2 steps: In liver and kidney | 1 step: In kidney | No activation needed: Cleavage of glycosides in the intestine |

FAQs
-
What is Panbovine®?
Panbovine® is a granulated form of waxy-leaf nightshade meal (Solanum glaucophyllum).
-
What is the difference between Panbovine® and Panbonis®?
Panbovine® is a microencapsulated product of micronized Solanum glaucophyllum leaves with a specific regular granulometry, free-flowing, especially adapted for the bolus manufacturing.
-
What is the regulatory status of Panbovine®?
The regulatory status of Panbovine® depends on the country. Please contact our team to get more information.
-
Why did Herbonis develop Panbovine®?
Panbovine® was developed to serve the dairy industry with an optimal product for bolus application in dairy cows.
-
What is the active component in Solanum glaucophyllum?
Glycosylated 1,25-dihydroxycholecalciferol (G-1,25(OH)2D3) is naturally occurring in the plant Solanum glaucophyllum and represents a unique source of the active form of vitamin D.
-
How does Panbovine® support the Calcium metabolism?
Vitamin D is a key factor in the regulation of the calcium metabolism. Vitamin D3 is converted in the liver and then the kidney to first 25-hydroxyvitamin D3 and then to its active form 1,25-dihydroxycholecalciferol (1,25(OH)2D3). In Panbovine®, 1,25(OH)2D3 is present as glycoside. After cleavage of the glycosides in the rumen, the free 1,25(OH)2D3 is absorbed and supports the cow in maintaining the serum Ca-concentration around calving.
-
What is the recommended application?
Panbovine® should be supplied through a bolus.
-
Can a claim be made on the prevention on hypocalcemia/milk fever?
In the EU, waxy-leaf nightshade meal is listed in Regulation (EU) 2020/354 establishing feed for particular nutritional use (PARNUT) reducing the risk of milk fever and subclinical hypocalcaemia.
