Optimizing Alfalfa Processing for Improved Pig Feed Quality

Sasov Biofarm, the largest organic pig farm in the Czechia since 2000, faced challenges with low pig daily gains and high feed consumption due to insufficient NL substances in their feed mixtures. To address this, they utilized dried alfalfa as a protein source, initially through purchased products and later as flour produced on-site. In 2011, a drying room powered by the farm's biogas station was constructed to ensure high-quality alfalfa production. To enhance feed quality, a line was established to separate alfalfa leaves and stalks, utilizing vibrating screen sorters and drum cleaners. This separation process increased crude protein content by 10% and decreased crude fiber content by 15%. The network separation system proved more efficient, allowing for easy adjustments by changing the device settings. Additionally, granulation presses and dispatch equipment were incorporated for improved handling and storage. This comprehensive project, supported by the rural development program, involved unbundling legumes, separating leaves and stems, shaping products, and establishing transport routes and dispatch equipment at the farm.
