Experior
Experior
Experior® is the first Health Canada-approved feed additive labeled to reduce ammonia gas emissions from an animal or its waste.¹ Experior, is approved for reduction of ammonia gas emissions per kilogram of live weight and hot carcass weight in beef steers and heifers fed in confinement for when fed during the last 14 to 91 days on feed.
Key Product Benefits:
- Reduces ammonia gas emissions.
- Flexible feeding window.
- Improved environmental stewardship and sustainability.
Indications for use:
- For reduction of ammonia gas emissions per kilogram of live weight and hot carcass weight in beef steers and heifers fed in confinement for slaughter during the last 14 to 91 days on feed.

The emission intensity of ammonia gas from Canadian beef production (measured as kg NH3 per kg of beef) decreased by 20%, from 0.17 in 1981 to 0.14 in 2011.2
Understanding gaseous emissions from beef cattle
Knowing the realities of the beef industry’s environmental impact is a starting point for addressing consumer demand for sustainable food. But, when it comes to gaseous emissions from cattle, there’s more than methane to consider.
What is Experior?
Experior is an important new product that enables beef producers to care for the environment and their cattle. Experior is approved for the reduction of ammonia gas emissions per kg of live weight and hot carcass weight in beef steers and heifers fed in confinement when fed during the last 14 to 91 days of feed
What does Experior do?
Experior helps support the beef industry’s environmental stewardship efforts. Every day, feedlot operators must balance expectations of increasing environmental stewardship, while managing a complex business. Experior creates the freedom and flexibility to do both through the reduction of ammonia gas emissions from cattle. Clinical studies show that cattle fed Experior at 5.5 g per metric ton for 91 days emit approximately 16% less ammonia per pound of hot carcass weight compared to animals not fed Experior.2
How does Experior work?
Experior is a beta-adrenergic agonist/antagonist that acts by increasing nitrogen uptake and the amount of nitrogen retained in the carcass as muscle protein, thereby reducing the amount of urea excreted in manure (manure is considered the urine and feces combined). The reduction in excreted urea from the animal results in a reduction in ammonia gas emissions to the environment.
Caution: Not approved for use in breeding animals because safety and effectiveness have not been evaluated in these animals. Do not allow horses or other equines access to feed containing Experior. A decrease in dry matter intake may be noticed in some animals.
Do not use concurrently with beta-adrenergic agonists such as ractopamine and zilpaterol.
No withdrawal period is required in beef cattle when treated according to the label.
The label contains complete use information, including cautions and warnings. Always read, understand, and follow the label, and use directions.
Indications for use: For reduction of ammonia gas emissions per kilogram of live weight and hot carcass weight in beef steers and heifers fed in confinement for slaughter during the last 14 to 91 days on feed.
Dosage: Feed 1.5 to 5.5 grams of lubabegron per tonne of feed (1.5 to 5.5 ppm), on a 100% dry matter basis, to beef steers and heifers fed in confinement for slaughter as the sole ration during the last 14 to 91 days on feed.
Ammonia gas emissions were measured for individual animals or small groups of animals held in environmentally controlled facilities. Based on existing information, reliable predictions of the reduction of ammonia gas emissions cannot be made on a herd, farm, or larger scale.
Increased rate of weight gain, improved feed efficiency, and increased carcass leanness have not been demonstrated with this product.
