ISSUE FOCUS 38 FEED & ADDITIVE MAGAZINE February 2024 GOING BEYOND DIGESTIBILITY Also important in today’s industry is the need for all ration ingredients, additives, and supplements to show they are working within the cow to lower her carbon footprint. Based on independent research results Selko was successful developing an independently verified LCA for use in dairy cows resulting in up to a 2% reduction in the cow’s carbon footprint per kg of energy corrected milk. Of greatest value is the fact that this benefit is free when using Selko® IntelliBond® to optimize rumen digestibility and trace metal availability within the cows. In addition to this important verification, Selko has recently achieved the verification of an additional LCA, which accurately identifies the carbon footprint for Selko® IntelliBond® C, Z and M (see Figure 3). This independent verification positions the Selko® IntelliBond® source of trace minerals as the first trace mineral source to offer nutritionists, formulators, and producers an accurate CO2eq value to use when working to reduce the carbon footprint of premixes, feeds, and rations in use within your herds nutritional program. In conclusion, when working to maximize the effectiveness of rumen digestion within your herd, your selection of the right trace mineral program can have a positive impact on rumen digestion, while improving the availability of essential trace metals to the animal. Based on the data reviewed from Michigan State a 1.66 point increase in NDFd gained from the replacement of sulphates could result in an additional 15,000 Kgs of 4% fat corrected milk per 100 cows.
