ISSUE FOCUS FEED & ADDITIVE MAGAZINE March 2022 51 Protected extracts from plant and seaweed to secure & boost milk production Recently, a new technology was introduced to modulate the rumen microflora and support milk production during the full production of dairy cows and maximize the production persistency beyond the production peak. Designed with a unique manufacturing process, this new technology is based on a special combination of key active ingredients. Ruminants live in symbiosis with the microorganisms hosted in their rumen. In this relationship, the animal provides the nutrients and the proper environment for bugs, while the microorganisms provide the possibility to convert non digestible dietary compounds into nutrients. While this symbiosis enables ruminants to take advantage of ingredients with theoretical low values, nutritional research has further explored fermentation mechanisms to possibly maximize the efficiency and the outcome of the symbiosis between the ruminants and the microorganisms of the rumen, to improve the production of energy or protein, reduce the waste of nutrients and again improve feed efficiency. The optimization of rumen fermentation should first be achieved through diet formulation and management practices. Nevertheless, when these strategies are implemented, additional benefits could be obtained by use of additives that can modulate rumen microbial fermentation. In recent decades, various technologies and ingredients have been used to improve the efficiency of energy and N utilization in the rumen but there is still room for news solutions that will allow the current level of production to be maintained without increasing costs. A SYNERGISTIC FORMULATION WITH CONTROLLED RELEASE TECHNOLOGY Recently, a new technology was introduced to modulate the rumen microflora and support milk production during the full production of dairy cows and maximize the production persistency beyond the production peak. This new technology relies on the exclusive combination of key active ingredients: • One “phycogenic” or marine algae with high content in phloro-tannins • Three “phytogenics’ or plant extracts with high levels of essential oils • One source of urea for a slow release of nitrogen Furthermore, this feed additive is designed with a unique manufacturing process: • A first outer-layer containing both phytogenics and phycogenics for a higher stability in feed and an immediate activity in the rumen and, Dr. Stephanie Ladirat R&D Director NUQO Feed Additives
