What are the benefits?
Supplementing breeding animals with StayDry Cal fills the calcium reservoirs in the bones ready for lactation, which reduces risk of hypocalcemia.
Calcium deficiency is likely to affect growing stock on deficient pastures because they have a high calcium demand in building their skeleton framework. The high potassium found in cereal crops (and other lush pastures) can inhibit calcium and magnesium uptake, making deficiencies in these minerals even more likely when grazing cereal crops. When supplemented to growing animals on calcium deficient pastures StayDry Hy-Cal:
- helps improve growth rates and build a robust skeletal framework
- Reduces risk of ricketts in lambs
It is well known that in winter there is an absence of Vitamin D. This is further exasperated by crops containing factors such as an excess of beta-Carotene and unbalanced mineral ratios and can lead to the development of rickets. Vitamin D is now also known to play a role in immunity and energy production.
Hy-D (25-hydroxycholecalciferol) is a unique ingredient in StayDry Hy-Cal. Hy-D is more bio available from the diet than Vitamin D3. As a result, animals are able to more efficiently absorb the Hy-D and can then produce more of the active Vitamin D in the body. Improved Vitamin D status means greater bioavailability of the critical minerals, calcium and phosphorus.

Hy-D 25-OH-D3 is the circulating available form of Vitamin D3
25-OH-D3 is absorbed in a similar way to but more rapidly than Vitamin D3
By passing the liver, Hy-D ensure optimal plasma levels of 25-OH-D3 and a more efficient production of 1, 25 (OH)2D3 active form of Vitamin D3
The benefit of being more efficiently absorbed than Vitamin D3 means Hy-D can boost the levels of the active Vitamin D metabolites in the plasma of the animals. Higher concentrations a Vitamin D metabolite has been shown in a series of studies at the University of New England to increase the absorption and retention of both calcium and phosphorus in heifers (Graph 1).
