Alltech has launched a tool to aid dairy nutrition and reduce methane emissions from animals.
The tool allows nutritionists to evaluate and troubleshoot dairy rations to maximize feed efficiency to combat rising feed costs. It also estimates the amount of energy lost as methane and methane emissions per animal, according to the company.
The In Vitro Fermentation Model (IFM) is a diagnostic tool that simulates rumen fermentation and evaluates the nutritive value of total mixed rations (TMR) in terms of digestibility and end-products formation.
Feed samples are incubated within a standardized rumen fluid and a buffer system to mimic natural rumen fermentation in an oxygen-free environment. IFM then measures gas production, identifies TMR inefficiencies and provides additional information on the nutritive value of the feed.
Greenhouse gas emissions from the rumen, primarily methane and carbon dioxide, contribute up to 45 percent of the total carbon footprint associated with the production of a pound of milk or beef, according to the Food and Agriculture Organization of the United Nations.
