# A new era in amino acid implementation

**Amino acid balancing** requires the combination of Lysine and Methionine. Kemin is the only supplier to offer both essential and complementary products to allow amino acid balancing in a reliable way. And the only partner to provide you with the know-how and support to achieve the most optimal results. At the same time, we are constantly looking for ways to innovate and further improve our customers’ outcomes. That is why we are proud to present a new era in amino acid implementation.

On this page, we show you all the answers you are looking for with regards to amino acid balancing and our **in-house developed Methionine solution**. We gathered insights from our own technical experience and from experts in the field. We interviewed, for example, Dr. Sergio Calsamiglia on his expertise in this topic. Watch the [video](https://info.kemin.com/exclusive-interview-sergio-calsamiglia?hsLang=en) here! 

In this video we proudly present our new in-house developed Methionine solution, **KESSENT®**;

# The quality of our Methionine solution and what it brings you

As a member of our industry you are facing several challenges in **protein formulation for ruminants**. All of these challenges impact you and your business. What are these challenges and how can we cope with them through feed optimization? We asked **Dr. Tanya Gressley** from the department of Animal and Food Sciences of Delaware University. 

Kemin’s new methionine solution is based on a state-of-the-art, accurate methodology developed by top ruminant and encapsulation scientists. As a result, KESSENT offers the **highest Methionine bioavailability** on the market. To achieve these optimal results, our technical experts are on hand to help you carry out the precise implementation of your amino acid balancing solution.

This new generation of amino acid implementation creates important benefits for you: better farm management, improved feed efficiency and a more flexible and precise formulation. It is an important step in animal welfare and sustainable farming. **And we are proud to lead the way**.

# The importance of specific gravity and particle size of rumen protected amino acids

**Increasing rumen-undegraded protein** is a big challenge of ruminant nutrition. It is both to meet protein requirements of the animals and to reduce nitrogen excretion in the environment by increasing the nitrogen efficiency.  F. Dufreneix, P. Faverdin, and J.-L. Peyraud, 2019, in the journal of Dairy Science, looked at possible **solutions**.  

One solution is the industrial processes using heat or tanning to reduce rumen protein degradation, but these have certain limitations. For example, the difficulty in balancing low ruminal degradation and high intestinal digestibility.

Another, more promising, solution is reducing the mean retention time (MRT) or increase the passage rate (Kp) in the rumen by varying the** size and specific gravity of particles**. This increases the rumen escape protein proportion of concentrate feeds and will improve the effectiveness of industrial processes. A Latin square experiment looked at the combined effect of size and specific gravity on the MRT of particles without interactions with microbial fermentations. A specific gravity of 1.2 to 1.3 showed to be optimal for the escape of particles. Smaller particles of concentrates lose functional specific gravity more rapidly than larger particles due to their higher fermentation rate. A diameter slightly greater than 3 mm seems to be a compromise to delay the start of fermentation and to allow for rapid passage through the reticulo-omasal orifice.

> The study shows the importance of specific gravity and particle size of rumen protected amino acids. Thus, achieving a good combination of particle size and specific gravity is critical for ensuring a high metabolizable amino acid amount into the animal.

 

## **Unbeatable particle size, specific gravity and homogeneity  **

When a new product is developed, it is crucial to take all the findings acquired by research into account. The **specific gravity** and **particle size** were two of the main requirements when KESSENT was being developed. Varying the size and specific gravity of the amino acid particles will increase the rumen escape protein proportion of concentrate feeds, as proven in the Latin square study (Dufreneix et al., 2019).

The optimal particle size and specific gravity of KESSENT allows it to move through the rumen rapidly, thus leading to reduced physical abrasion and microbial degradation in the rumen and consequently, to **increased intestinal bioavailability**.

- Specific gravity is 1.21, ensuring a rapid escape from the rumen         
- 95% of the particle size is lower than 2.2 mm, ensuring a rapid exit into the abomasum      
- The standard deviation and coefficient of variation for both the specific gravity and the particle size are very low, and lower than any other rumen protected Methionine available on the market. This property allows a better homogeneity and stability under real field conditions

When developing our KESSENT technology, a **3-step process** known as **Process for Rumen-Protected Amino Acids Validation Criteria** was used. The 3-step process includes research conducted *in vitro* in the laboratory,* in vivo* in the animal and at field level in dairy farms. These researches proved the greater bioavailability of KESSENT compared to other available rumen protected Methionine products. This greater bioavailability is attributed to the particle size, specific gravity, high Methionine content and encapsulation technology.
