ISSUE FOCUS 52 FEED & ADDITIVE MAGAZINE March 2022 • a second inner-layer made of protected urea for a slow and continuous release of nitrogen in the rumen, to support and maximize the production of protein The exclusive composition of this technology combined to its unique manufacturing process allow this technology to be an all-in-one solution with each particle containing all active ingredients for homogeneous distribution in the feed and consistent efficiency. MODULATING RUMEN METABOLISM TO SUPPORT PERFORMANCE All active ingredients are protected and delivered to the rumen to acts synergistically and modulate rumen functions to boost performance of dairy cows. • The phytogenics & phycogenics, which are released first, will indirectly favor bacteria that optimize VFA production, and thus trigger an energy uplift • The inner core containing protected urea acts as a micro bolus to release nitrogen progressively, which together with the energy uplift will favor the production of innate microbial protein in the rumen. • In the meantime, phytogenics & phycogenics control the detrimental microflora, i.e. inhibit protozoa and bacteria that are responsible for proteolysis and deamination With an uplift of energy, an increase of nitrogen available for the rumen microorganisms, and a reduction of amino acid degradation, the three steps above consequently work synergistically to increase the total protein flow to intestine and support milk production. Finally, phytogenics are also acting on digestibility since specific phytogenics can increase digestive secretion. This enhanced digestibility will lead to a better digestion and absorption of nutrients and further support the milk production of dairy cows. SECURING & EXTENDING MILK PRODUCTION CYCLE Several in-vivo trials have demonstrated the impact of this new technology, either ‘on top’ to boost milk production and extend milk production after the peak, or by reformulating the share of proteins in the diet to optimize profit. The research has shown that animals benefit from this technology through a better support of their protein metabolism and through the modulation of the VFA profile production in the rumen. In all trials, the new technology, based on exclusive metabolites and technology, was shown to contribute to higher milk production, with no dilution of fat and protein and a better feed efficiency. In a new trial, the technology was tested at a Belgium dairy farm in March 2021. Cows were originally fed with a ration based on raw materials (no feed additives) with a 1:1 corn:grass silage, and with a crude protein level between 14,54% to 14,75% depending on milk production. Two groups of cows were homogeneously split and either fed with standard diet (NC) or with this new technology (PC). At day 60, cows in the NC group started with a slightly higher milk rate vs cows in the PC group. After the peak of lactation (>d60), cows progressively produce less but cows in the PC group maintained a higher production rate per day than cows in the NC group. With a longer lactation period, the effects of the technology were step by step more visible: cows from the PC group produce 1.1 litre more than the NC group from 60 to 250 days, 1.4 litre more from 60 to 280 days and, finally, 1.9 litre more from 60 to 330 days!
