ISSUE FOCUS FEED & ADDITIVE MAGAZINE March 2022 53 results confirm outcomes from previous trials and the effect of the innovation to support milk production, and more specifically to increase the performance over the time and extend the production cycle of dairy cows. Interestingly, the cows from the PC group, which had a higher milk production than cows from control diet, also maintained their fat% and protein%, indicating no dilution of the milk. These results confirm the effects of PC treatment on protein metabolism and energy in the rumen. As an example, the PC treatment showed an effect on VFA production, with an increase of the ratio of propionic:acetic acid, which represents a gain of energy for the cows. This highlights the effect of the new product on ruminal microflora, to alleviate the fermentation pathways and optimize rumen efficiency. A COMPREHENSIVE TOOL TO SECURE MILK PRODUCTION Considering its importance in cow production, it is not surprising that the rumen and its ecosystem have monopolized most nutritional research. Nevertheless, progress in research has unveiled new opportunities for animal nutrition, to further understand and possibly alleviate the metabolism of rumen, to improve feed efficiently and better take advantage of available diet compounds. While various molecules or ingredients have been tested and are commonly used to support the production of dairy cows, the technology presented in this article relies on a quite unique approach, with a synergistic effect of its components, thanks to a simultaneous release of nitrogen and an uplift of energy. This is the outcome of a transparent and exclusive formulation, in particular when it comes to phycogenics from algae, but also the outcome of the manufacturing process that enables the specific controlled release of ingredients in the rumen. This innovation is now available on the market and can be used as a tool to support and extend milk production, while other declinations will be developed in the future to address more specifically different life stages of animals. About Dr. Stephanie Ladirat Dr. Stephanie Ladirat is the technology director at NUQO. She obtained her MSc degree in Food Technology with a specialization in Food Ingredient and Functionality and her PhD degree in Food Chemistry fromWageningen University (The Netherlands). During her PhD thesis, she studied in depth the human gut microbiota composition and its modulation upon prebiotic supplementation and/or antibiotic treatments. From 2014 till 2020, she worked at Cargill Animal Nutrition, first as technology lead for gut health additives and, then, as swine portfolio manager. She provided global technical product support for a broad range of products (phytogenics, organic acids, short and medium chain fatty acids, probiotics) and trained technical and sales teams. She most recently managed R&D projects and developped innovative feed additive solutions to answer specific customer needs related to animal gut health and performance.
