Studies and Research Summaries

Lysine Availability in AminoMax Pro

This study discusses the effect the patented AminoMax process has on the digestibility of the amino acid lysine.

Comparison Between AminoMax and Commercial Soybean Meal Blend - March 2014

AminoMax was compared to a well-established treated soybean meal to see how each performed in terms of cow weight gain, milk yield, dry matter intake and other metrics. The study showed that AminoMax provides an excellent amino acid balance for dairy cows.

AminoMax Process Using the Cornell System: Product Consistency - June 2013

Essi Evans, Ph.D., evaluated samples of canola and soybean meal to measure the consistency of meals treated using the AminoMax process. The results showed that the rumen undegraded protein (RUP) as well as RUP digestibility were maintained within a very narrow range.

AminoMax in Mid-Lactation Diets - June 2013

This study conducted by Essi Evans, Ph.D., compared milk yield, weight gain and other metrics among cows who were fed an AminoMax blend with those fed the two main components—soybean and canola meal—separately. The results showed that milk yield and weight gain were both higher for cows fed AminoMax.

AminoMax Process Using the Cornell System - May 2013

Essi Evans, Ph.D., analyzed and compared canola and soybean meal that had been processed using the AminoMax process to unprocessed meal. The study showed that RUP content was substantially increased for both after processing.

AminoMax Process Using the Cornell System: Effects of Particle Size - May 2013

Essi Evans, Ph.D. compared small particles of AminoMax Pro to intact meal and found that the AminoMax process was consistently applied throughout the meal and not confined to the external surface of particles.

Development of an in vitro Assay to Measure Intestinal Protein Digestion and Why

The paper discusses a new process that was developed to be compatible with commercial laboratory procedures. The new procedure offered increased accuracy for both metabolizable protein and rumen nitrogen balance predictions and evaluations.

A Comparison of Methods to Evaluate in vitro Intestinal Digestibility

The study explores how in vitro and in situ ruminal digestion affect the IV intestinal appearance of feed dry matter and nitrogen as part of enzyme standardization work.
