Are you experiencing reproductive problems, low immune systems, mastitis, loss of livestock or decreased performance at the farm?

It could be selenium and vitamin E deficiency!

PROBIOSEL E 25000 is your best solution.


Why is PROBIOSEL E 25000 important in animal nutrition?

Selenium and vitamin E are essential to both farm animals and performance animals such as horses. They play a vital role in each stage of the life cycle from conception and growth through production and reproduction. Selenium is an integral component of the enzyme glutathione peroxidase, which in combination with vitamin E protects the cell membrane from oxidative damage during stressful periods.

Deficiencies in selenium and/or vitamin E may result in a myriad of diseases or metabolic disorders, which can cause significant economic and livestock loss. White muscle disease, reduced fertility, and a decrease in the immune response are the most common manifestations of selenium and vitamin E deficiencies in different species.

What causes deficiencies?

1. Selenium-deficient pastures.
2. Increased stress during pregnancy, production, racing, endurance work and disease.
3. Unbalanced diets.
4. Vitamin E deficiency occurs when an animal’s diet contains insufficient green forages and too much dry feed–such as hay and grain–for long periods.

Which animals are most susceptible to deficiencies?

• In general deficiencies have been reported worldwide in all animal species, but rapidly growing animals are more vulnerable.
• Animals under physiological and pathological stress.

What are the benefits of PROBIOSEL E 25000?

• The judicious choice of ingredients: vitamin E and organic selenium play an important role in the body as they counter oxidation caused by free radicals and promote a healthy metabolism.
• With its organic ingredients, PROBIOSEL E 25000 is a valuable source of bioavailable selenium and vitamin E.
• The antioxidant capacity of PROBIOSEL E 25000 meets the requirements of animals at every life stage.
• Improves dry matter intake in animal and feed utilization.
• Increases reproductive performance.
• In addition to selenium and vitamin E, the calcium carbonate boosts immune function to achieve optimal animal health.
• Increases the milk yield and dairy product quality, which then contains a natural source of selenium to benefit the health of human consumers.
• Increases the selenium and vitamin E concentrations in colostrum and milk. It is reported that a very limited amount of vitamin E can pass the placental barrier, which is why the colostrum remains the primary source of vitamin E for new-born animals.
• Plays an important role in both male and female reproduction.
• Supplementing females in late pregnancy is the best way to prevent congenital white muscle disease in the offspring.
• When supplemented during late pregnancy, it helps to prevent retained placentas.
• When supplemented during the dry period, it improves the immune system of the udder and prevents incidences of mastitis.
• Prevents the occurrence of white muscle disease in adult animals exposed to different physiological and pathological stresses.
• In addition to these benefits, PROBIOSEL E 25000 improves wool production in sheep and goats.
• The quantity and the fermenting capacity of the yeast (saccharomyces cerevisiae) that carries the PROBIOSEL E 25000 content improves rumen health and increases the appetite.

What are the benefits of PROBIOSEL E 25000 for the producer/owner?

• To avoid unnecessary expenditures to treat critical cases of selenium deficiency.
• To reduce animal stock mortality.
• To produce quality dairy products.
• To produce healthy animals which can overcome various stresses.
• Together, vitamin E and organic selenium are a winning combination: in addition to their role as an antioxidant, they promote the body’s immunity and resistance to disease.

Special note:

• Prior to supplementing, it is necessary to assess the animal’s current selenium and vitamin E status.
• While supplementing with PROBIOSEL E 25000, any other source of selenium must be avoided.
• Proper dosage should be followed to meet each animal’s requirements according to its species, age, and physiological status.
