An in vitro study to assess the effect of Anpario’s Optomega range on gas and methane production when supplemented in the dairy herd ration showed that both products in the range helped lower cumulative gas production over a 24-hour period.
The study was carried out by the University of Reading in association with independent feed additive manufacturer Anpario. Optomega Algae and Optomega Plus were supplemented at 100 g/cow/day and 160 g/cow/day respectively and gas pressure readings were taken at regular intervals. Methane analysis was carried out using gas chromatography.
The results of the trial showed that alongside the main fertility benefits associated with supplementation, both Optomega products helped to lower cumulative gas production over a 24-hour period. Compared to control diets, the cumulative methane output was 10.8 percent lower in Optomega Plus supplemented cows and 6.6 percent lower in cows fed diets supplemented with Optomega Algae.
Dr Wendy Wakeman, Anpario’s global technical director, says, “To put the results into context, for a 200-cow dairy herd, the lower methane output could support a reduction in carbon footprint of up to 80 tonnes per year of CO2-equivalents with Optomega Plus, and up to 51 tonnes per year with Optomega Algae.”
“There is global pressure on the ruminant sector to reduce methane output, especially from dairy cows. Hence, it is extremely beneficial for producers that alongside the proven fertility and milk benefits, the addition of Optomega products to diets has also been shown to help lower methane production”, continues Dr Wakeman.
The Optomega Range provides products renowned for their rich source of omega-3 fatty acids. This includes biologically important eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which offer a multitude of benefits for dairy producers. Optomega products have demonstrated efficacy in supporting the establishment and maintenance of pregnancy, aiding mammary gland development, optimising milk yields, and enhancing omega-3 levels in milk for human consumption.
The range includes the well-established Optomega Plus, which offers a rich source of EPA and DHA, and the recently launched Optomega Algae which provides a source of the omega-3 fatty acid DHA. Products are formulated on a unique carrier system provide a dry, free-flowing powder and are packaged in foil-lined bags for optimum shelf-life and product freshness.
“Optomega provides dairy producers with a choice of high-quality omega-3 fatty acids which have been derived from either fish oil or microalgae, both of which are responsibly and sustainably sourced”, concludes Dr Wakeman.
