Are You Sure That Your Sheep Bolus Is Still Authorised For Use In Ireland?

Dr. Elizabeth Berry BVSC, PhD, MRCVS, Veterinary Director with Animax confirms that all of their Allsure® boluses contain Selenium Selenite and authorised for use with sheep, lambs, and cattle.

Many farmers are unaware that since July 17, 2019 Selenium Selenite is the only Selenium approved by the EFSA (European Food Standard Agency) as a feed additive for use in sheep boluses sold in Britain, Ireland and the rest of Europe.

So immediately check that the product you are using complies with these EU regulations.

Grass and forage vary widely in trace element content due to soil type, pH, drainage, plant species and fertiliser use.

Certain root crops are also known to be low in selenium and vitamin E.

Dr Berry says that “Selenium is essential for a wide variety of immune responses in cattle and sheep and a deficiency can impact on overall production.

For example, a selenium deficiency can reduce the effectiveness of white blood cells by altering both their numbers, activity and speed getting to the site of infections.

Clinical signs of selenium deficiency include late abortion, stillbirth, or weak calves or lambs with enlarged thyroids, retained placenta, low immunity to infection in all ages of cattle and reduced fertility in bulls.

It may also cause muscular stiffness, recumbency, difficult breathing and poor weight gains in younger cattle.

Other symptoms may include early embryonic loss or failure to implant after mating.

Or a newly calved cow may have retained cleansings or an increased susceptibility to mastitis, both of which can result in delayed oestrous after calving.

Speaking at a recent technical briefing for animal health distributors Dr Berry pointed out that access to minerals at grass can be very variable, while water supplementation can make the water unpalatable.

If adding trace elements to a ration you always run the risk of variable intakes.

Drenches can be applied but need to be repeated frequently.

According to Dr Berry “One of the most effective and convenient way is to give all animals a slow release bolus.

The bolus will ensure that each animal gets the required levels to offset any deficiencies in a grazing system.

Ensuring trace element requirements are met at this critical time of year will not only prepare ewes and lambs for a fertile breeding season but will also help to reduce the chance of unknown issues arising, and the associated stress.

Rory Dicker, Commercial Manager pointed out that the Allsure® sheep range of intra-ruminal, leaching boluses use unique and proven leaching technology to provide slow release supplementation of the four essential trace elements [Cobalt, Copper oxide, Iodine and Selenium] at known and optimum levels for up to 6 months.

Flor Ryan, the Animax sheep specialist says that the Allsure® sheep boluses are easily given to ruminant animals using a specially designed Animax applicator.

The bolus enters the animal’s rumen-reticulum and lodges there. The trace elements then leach out from the bolus at a known rate and the used boluses are shed naturally.

Animax will have an attractive special offer for customers on their stand in the IHFA marquee (row 7, block 3, stand 167) during the National Ploughing Championships.

Animax will give away a free bolus applicator with all bolus orders for drying off or pre tupping.
