and for complete and complementary feedingstuffs respectively, 5 or 10 ppm Lead and 2 or 4 ppm Arsenic. For Hydroxy Copper the legal maximum limit for Arsenic was increased from 30 to 50 ppm and recently the same increase is regulated for Hydroxy Manganese upon a producers’ request. However, Excential Smart products easily meet the lowest standards since Arsenic levels are largely below 10 ppm. It is our duty and engagement to keep these levels as low as possible, and to ensure that our customers use the safest and purest trace element sources available
Hydroxy trace minerals (Excential Smart range by Orffa) are the best choice to optimize the trace mineral supply to your customers’ animals. They have a high mineral content compared to inorganic as well as organic minerals, are not hygroscopic and are dust-free enabling perfect flowability and are cost effective in use in feed, premix and
mineral mix. They are the safest and purest mineral source available to the industry.
Excential Smart C EU 3b409 (> 54% Cu)

Excential Smart Z EU 3b609 (> 56% Zn)
Crystalline Zinc chloride hydroxide monohydrate
Excential Smart M EU 3b507 (> 50% Mn)

The Impact of Low Protein Diets and Amino Acids in Dairy Production By Holly Malins, Evonik Nutrition & Care
Improved health, production and the support of low crude protein diets have been enabled through the use of supplemental amino acids in monogastrics for decades. Application of rumen protected amino acid products in the UK dairy industry has started to gain speed in the last few years, as more research has been carried out showing the benefits. Evonik held a customer seminar in November focused on the impact of low protein diets and amino acids in dairy production to help propagate further understanding in the UK.
The morning was focussed on low crude protein diets, with Professor Chris Reynolds from the University of Reading giving a detailed overview of a 6-year trial carried out at the UK Centre for Dairy Research (CEDAR). This trial looked at the impact of different levels of dietary crude protein on nitrogen excretion, as well as consequential impact on the productivity, health and longevity of the cows in the groups over three lactations. The findings showed that without amino acid balancing, 16% crude protein had the best performance compared to 18 and 14% dietary crude protein. His presentations were complementary to a session on practical low protein diet formulations from Dr Claudia Parys, Evonik’s Global Ruminant Technical Service
Manager, which focused on reducing crude protein even further through the supplementation of rumen protected amino acids. Dr Parys also showed a collection of UK diets that, despite having a range of crude protein levels between 14.3 to 17.9%, were all deficient in methionine. This provides evidence to support the concept that we need to think more of the digestible amino acid content of the diets, rather than total crude protein, as is often still the case.
The afternoon started with a look at Evonik’s rumen protected methionine, Mepron®
, and how its slow release coating technology
means it outperforms the competition on handling properties, rate of metabolizable methionine delivered and cow performance. This was
