Solutions to Oxidative Stress
A dairy cow’s nutrition program can help maintain oxidative balance. The nutrition program can benefit from the proper balance of antioxidants, minerals and amino acids.
   
Antioxidants as a Solution
Feeding the antioxidant AGRADO® Plus feed ingredient in dairy rations has been shown to improve the antioxidant status of the animal, negate the effect of feeding fat on rumen microorganisms, stabilize dietary fat and lipid soluble vitamins as well as improve milk production and milk fat levels. Research on AGRADO Plus shows it can improve milk production while keeping cows in oxidative balance. In fact, trials show AGRADO Plus can improve milk fat by more than 6 percent. Additionally, an increase of more than 5 percent in fat-corrected milk (FCM) can be demonstrated with feeding AGRADO Plus. Finally, feeding AGRADO Plus has been shown to increase milk yield by more than 1.5 percent.
   


AGRADO Plus can also benefit a ration by stabilizing dietary fat in the diet. This prevents oxidation of the feed ingredients, reduces free radicals in the diet and digestive tract and improves tissue integrity.
Value of Quality Trace Minerals
Mineral supplements such as MINTREX® chelated minerals are key for tissue integrity and strength, as well as the long-term health and welfare of cows. Minerals are also key components of antioxidant enzymes. Unlike some other trace minerals, MINTREX limits exposure to oxidation, keeping a cow’s system in better oxidative balance.
   
Selenium and Its Role
Selenium, in forms such as ZORIEN® SeY yeast feed additive, is vital to keeping a cow’s system in balance. Selenium is a key mineral cofactor for glutathione peroxidase. Hydrogen peroxide is a significant source of oxidative stress. Glutathione peroxidase is the enzyme that converts hydrogen peroxide into water.
   

 
Value of Methionine in a Dairy Cow
Methionine analogs, such as ALIMET® and MFP™ feed supplements, play many roles in the cow. Along with increasing milk, fat and protein yield, ALIMET contributes to keeping the cow in balance. For instance, methionine is one of the amino acids that is essential for protein synthesis. Feeding ALIMET and MFP increases microbial protein production, which contributes to maintenance, builds enzymes and supports the immune system response.Another key benefit to feeding ALIMET and MFP is the role methionine plays as a precursor to cysteine. Methionine can also be converted to the amino acid cysteine, which is used extensively by the immune system. Oxidative stress and lipid peroxidation are known results of animal exposure to mycotoxins. In fact, mycotoxins are among the most important feed-born factors contributing to oxidative stress. Therefore, proper mycotoxin management programs will contribute to reducing oxidative damage. Adding products such as SOLIS® anti-caking agent to dairy rations can help to reduce oxidative stress caused by mycotoxins.
