Hi, [NUTRITIONIST FIRST NAME]

I came across this protein blend product and thought it might be worth a look. Do you think something like this could make sense for our ration?

Excelene™ protein blends

A customizable alternative to blood meal or commodity byproducts, Excelene protein blends provide ideal levels of nutrients to dairy cows for optimal feed conversion. The latest research has shown specific amino acids, such as methionine, isoleucine, leucine and lysine, can be used to preferentially drive milk protein, fat and yield.

Proven across 15 commercial trials.

In over 15 commercial demonstrations, using Excelene proteins to balance for amino acids beyond lysine and methionine resulted in 1 point of additional milk protein on average.¹
Substituting commodity blood meal with an Excelene blend designed to replace blood meal increased IOFC by $0.14 per cow per day.²
Recent research has shown that supplementing amino acids like isoleucine, leucine and arginine, key amino acids present in Excelene proteins, can drive both milk fat and milk volume in addition to supporting milk protein yield.^3,4,5

More reliable than straight bloodmeal and commodity byproducts.

Data demonstrates that Excelene blends can help you kick variability to the curb. See three years of data charting the deviations in blood meal, soybean meal and more protein options.

Consistent quality, load after load.

Our industry-leading program involves regularly screening suppliers, analyzing ingredients and testing finished products to create efficiency through consistency. We separate ourselves from the competition with a rigorous quality control process, third-party validation and frequent, transparent reporting. See the steps involved in Papillon’s quality control process.
