Sel-Plex®

A Superior Source of Organic Selenium

Evidence from over the last 20 years indicates that the form of dietary selenium is key to its efficiency. This has led to an industry-wide shift toward safer, organic forms of selenium and a move away from the traditional inorganic form of sodium selenite. Selenite’s high toxicity, pro-oxidant properties and bioavailability have caused the industry to question its use.

Sel-Plex® is Alltech’s proprietary organic form of selenium yeast. It is an excellent dietary source of selenium and is manufactured to mimic Mother Nature. The selenium from Sel-Plex is safer and better able to meet the higher requirements of livestock raised for rapid growth, reproductive performance and health.

Episode 4 is available now! Selenium yeast vs. HMSeBA – Is there any difference?

We investigate the differences between organic selenium enriched yeast and a newer, chemically synthesized product called HMSeBA, which is also classified as an organic selenium, and answer the question, “Are these products the same, and is this new product organic?”

Organic trace minerals for dairy cattle

The average dairy cow is not meeting her genetic potential. Reaching genetic potential begins with feeding dairy cows correctly at every life stage, including before birth. Including a selenium supplement in the diet is crucial for the profitability of the herd. Selenium deficiency in dairy cows is related to various diseases, along with decreased productive and reproductive performance.

Benefits of organic selenium in dairy cows:

  • Supports metabolic processes
  • Supports reproductive health and herd longevity
  • Acts as an antioxidant
  • Protects the integrity of tissues
  • Protects muscles from degeneration
  • Supports against infection
  • Supports fertility/conception rates

Organic trace minerals for beef cattle

Most of the world’s agricultural areas are in regions where feed and forages have suboptimal selenium levels. Selenium deficiency in beef cattle can cause serious issues, including hoof health, respiratory, disease and mastitis challenges, which can affect overall profitability.

Benefits of organic selenium in beef cattle:

  • Supports antioxidant status
  • Supports normal reproductive function
  • Supports meat quality and nutritional value of meat
  • Promotes proper reproductive health
  • Promotes disease defense
  • Improves response to respiratory and disease challenges

Organic trace minerals for poultry

Selenium deficiency in poultry diets can lead to several adverse effects, such as poor feathering, reduced egg production, suppressed immunity and diseases that can cause significant profit losses for a poultry operation. Sel-Plex, an organic selenium yeast, better meets the needs of modern-day birds and has a practical impact on poultry health and performance.

Benefits of organic selenium in poultry:

  • Chick health
  • Feather quality
  • Healthy antioxidant status
  • Eggshell quality (increased freshness and thickness)
  • Egg production
  • Nutritional value of meat
  • Reproduction
  • Maintenance of the body’s defense system

Organic trace minerals for pigs

Selenium deficiency in pigs can cause slower growth rates, diseases and even death among young piglets. Selenium toxicity in pigs (an excess of selenium) has been known to interfere with the absorption and utilization of other essential trace minerals, such as zinc. Sel-Plex is an organic selenium yeast, proven to enhance performance by providing selenium in a form naturally present in plants and more digestible than inorganic forms.

Benefits of organic selenium in pigs:

  • Supports reproductive health and sow longevity
  • Promotes piglet viability
  • Optimizes immune response and antioxidant status
  • Improves meat quality and the nutritional value of meat
  • Has improved FCR, ADG and carcass weight

Organic trace minerals for aquaculture

Selenium deficiency in aquaculture diets can lead to several adverse effects, such as poor growth rate, decreased performance, suppressed immunity and diseases that can lead to significant profit losses. Sel-Plex, an organic selenium yeast, delivers a superior source of selenium with the benefits of antioxidants. Hence, there is great potential to increase the efficiency of fish and shrimp production through selenium nutrition.

Benefits of organic selenium in salmon:

  • Improves meat quality
  • Improved pigmentation
  • Higher growth rate
  • Reduced filet gaping
  • Increased selenium muscle content

Benefits of organic selenium in tilapia:

Tilapia for breeding:

  • Improves performance of progeny
  • Improves feed conversion ratio (FCR)
  • Higher fry survival %
  • Higher weight gain

Tilapia for harvest:

  • Higher weight gain
  • Higher length gain
  • Improved FCR

Benefits of organic selenium in shrimp:

  • Supports growth
  • Optimized immune performance
  • Increased plasma protein levels
  • Increased blood cell levels
  • Higher selenium muscle content

Organic trace minerals for equine

Selenium deficiency in equine can cause problems such as impaired muscle function, heart health, immune function, growth and energy levels in your horse. Selenium toxicity in horses (an excess of selenium) has been known to interfere with appetite and digestion, muscle weakness and fever, among other risks. Sel-Plex is an organic selenium yeast, proven to enhance performance by providing selenium in a form naturally present in plants and more digestible than inorganic forms.

Benefits of organic selenium in equine:

  • Colostrum quality and efficient transfer of selenium from mare to foal
  • Nutritional status of the foal
  • Normal reproductive function
  • Exercise tolerance
  • Performance of recreational horses
  • Nutritional value of horse feeds and supplements

Supported by more than 30 years of research

As we demand more from our animals, we must demand more from our minerals

Selenium is involved in numerous important systems within the body, including antioxidant defense, reproduction and immune function. Through the use of Sel-Plex, we are able to boost the selenium status of livestock animals reliably and safely, allowing the buildup of nutrient reserves for periods of increased antioxidant demand and stress without risking toxicity.

Improved nutritional value of food products

Like animals, people often do not get enough selenium in their diets. Functional or enriched foods offer consumers a way to get the most from their diets.

Sel-Plex is proven to improve the performance and efficiency of food-producing animals and naturally enhance the nutritional value of meat, milk and eggs.

In 2009, the European Food Safety Authority (EFSA) recognized several human health claims for Sel-Plex-enriched meat, eggs and milk.

Proven

Sel-Plex is the first FDA-reviewed form of organic selenium and was also the first strain-specific form to be EU-approved in all species.

Traceable

Sel-Plex is manufactured, packaged and sold by Alltech using highly controlled manufacturing processes and quality control methods.

Safe

Supported by more than 30 years of research, Sel-Plex is the most researched and proven form of organic selenium.

Bioavailability

Improved selenium uptake and tissue retention when livestock is supplemented with Sel-Plex compared to inorganic selenium.

Complete

Sel-Plex is designed to completely replace all inorganic and organic selenium sources in the diet.
