Abstract
It has been found that administering 25-hydroxy vitamin D3 to ruminants helps to reduce the need for supplemental inorganic Ca in the diets while maintaining milk production or growth performance.. Thus the aspect of this invention is a method of promoting Calcium absorption in ruminants, comprising administering a sufficient amount of 25-hydroxy vitamin D3 to the animal.
Description
USE OF 25-HYDROXY VITAMIN D3 TO PROMOTE CALCIUM
ABSORPTION IN RUMINANTS
It is well recognized that animals respond to Calcium (Ca) supplementation in terms of improved breeder fertility, improved frame size and growth rates. Large areas of grazing land around the world in particular South Africa, South America and Northern Australia are extremely Calcium deficient. Supplementation with Calcium is commonly used to improve animal productivity in these areas.
A large amount of calcium is present in animal feed in form of organic or inorganioc salt. Calcium present in the diet not absorbed and not incorporated into tissue or milk is excreted via faeces and urine. It is the object of the present invention to suggest a method of promoting or improving Calcium absorption in ruminants.
In accordance with the present invention it has been found that administering 25- hydroxy vitamin D3 to ruminants helps to increase Calcium absorption and maintain higher blood Calcium concentrations in cattle offered a low calcium diet. This may reduce the need for supplemental inorganic or organic Ca in the diets while maintaining milk production or growth performance. Furthermore, the excretion of Ca with the manure will be reduced and thus a positive effect on the environment will be achieved. Thus one aspect of this invention is a method of promoting calcium absorption in ruminants, comprising administering a sufficient amount of 25-hydroxy vitamin D3 to the animal.
As used throughout the specification and claims, "25-OH D3" means 25-hydroxy vitamin D3. There are about 150 species of ruminants which include both domestic and wild species. Ruminants include cattle (bovines), goats, sheep and camels. Preferred ruminants according to this invention are cattle, for example dairy cows and beef cattle.
While many benefits of supplementing a diet with Vitamin D and/or 25-OH D3 are known, especially regarding bone health, little is known about Vitamin D and its derivatives' effect on calcium absorption in the animal.
For example, Tritsch et al. (US 2003/0170324) disclose a feed premix composition of at least 25-OH D3 in an amount between 5% and 50% (wt/wt) dissolved in oil and an antioxidant, an agent encapsulating droplets of 25-OH D3 and oil, and a nutritional additive (e.g., Vitamin D3). The premix may be added to poultry, swine, canine, or feline feed. This composition stabilizes 25-OH D3 against oxidation.
Simoes-Nunes et al. (US 2005/0064018) discloses adding a combination of 25-OH D3 and Vitamin D3 to animal feed. In particular, about 10 μg/kg to about 100μg/kg of 25-OH D3 and about 200 lU/kg to about 4,000 lU/kg of Vitamin D3 are added to swine feed. This addition improves the ruminant's bone strength.
Stark ei al. (US 5,695,794) disclose adding a combination of 25-OH D3 and Vitamin D3 to poultry feed to ameliorate the effects of tibial dyschondroplasia. Borenstein et al US 5,043, 170 discloses the combination of Vitamin D3 and either 1 -alpha-hydroxycholecalciferol or 1 -alpha, 25-dihydroxycholecalciferol to improve egg strength and leg strength in laying hens and older hens.
While not wishing to be bound by theory, it appears that 25-OH D3 shows an effect on P metabolism in two ways: On one hand it stimulates P absorption from the gastrointestinal tract and on the other hand it improves bioavailability of P into tissues.
For the purposes of the invention, 25-OH D3 is suitably administered as supplement to animal feed. Feed may be supplemented by admixing 25-OH D3 , e.g., as a commercial formulation such as available under the Trademark
ROVIM IX® Hy D® 1.25% to regular feed or by first preparing a premix of a feed component and 25-OH D3 and subsequent mixing the premix with other feed components. The feed can be any conventional ruminant feed. The term feed as used herein comprises both solid and liquid feed as well as drinking fluids such as drinking water.
Particularly, 25-OH D3 can be administered to the animal in form of a slow release bolus either alone or with other compounds such as rumen modifiers, ionophores, methane inhibitors etc or as a formulated powder to a premix containing other minerals, vitamins, amino acids and trace elements which premix is added to regular animal feed and thorough mixing to achieve even distribution therein.
Generally, 25-OH D3 is added to the feed in an amount required to administer from about 0.1 μg to about 5.0 μg, especially about 0.5 μg to about 3.0 μg 25-OH D3 per kg body weight of an individual animal per day.
More specifically, in the manufacture of a ruminant feed in accordance with the invention, from about 10 μg/kg to about 1000 μg/kg of 25-OH D3 are suitably added to regular ruminant feed. Alternatively, a feed premix may be prepared on the basis of regular feed components by adding active ingredients to such feed components in higher concentration, e.g., in a concentration of from about 10 mg/kg to about 1000 mg/kg of 25-OH D3. If one kg of such premix is added per 1000 kg of regular feed this would typically meet the individual need of the animal by normal feed consumption.
For dairy cows and beef cattle, the dosage can range from about 10 μg to about 1000 μg per kg cattle feed diet, preferably from about 50 to about 80 μg 25-OH D3 per kg diet. For other ruminants, the amounts are similar, and can be based on the amount of feed given per day. For optimum results, the 25-OH supplementation should be part of a diet which contains an adequate supply of nutrients, generally known to be of benefit to the organism.
The efficiency of the treatment of cattle in accordance with the invention can be seen from the experiments described below. In an experimental cattle farm, two groups of animals were selected for the following experiment with a low Calcium diet.
One group received the control diet which was the standard roughage diet without the supplementation of 25-hydroxy-vitamin D3. The other group received the experimental diet which was the standard roughage diet supplemented with 2,000 μg 25-hydroxy-vitamin D3 per head/day
After 1 , 1 1 , 12, 13 and 14 days the blood plasma concentration of Calcium was measured by standard method. The results (Figure 1 ) show a significant increase in Calcium concentration in blood plasma for the group with the experimental diet at least after 10 days. Additionally the Calcium concentration in g/day was measured or/calculated in the diet, faeces and urine. The results are summarized in the table below and are consistent with measured plasma concentrations as shown in Figure 1 . The results also show a significant decrease of P excretion by the animal after 25-OH D3 supplementation.
