<p>The present invention relates to cattle feed using an expander, and more specifically, to cattle feed using an expander to improve the usage of low-priced materials, cattle feed preference, and meat quality by expanding different raw materials with high temperature and pressure when producing the cattle feed and then mixing them in order to reduce the process and enhance production efficiency as well as digestion rate. The cattle feed using expander of the present invention includes 23-25 wt% of soybean cake; 18-20 wt% of repeseed meal; 45-50 wt% of palm kernel expeller; 23-25 wt% of distillers dried grains; 45-50 wt% of coconut meal; and 4-5 wt% of limestone on the basis of 100 wt% of corn and features that the corn, soybean cake, repeseed meal, palm kernel expeller, distillers dried grains, and coconut meal are ground in 2-4 mm, and supplied to the expander for single expansion at the temperature of 160-180 deg. C and pressure of 3.5-5 kg/m^2 for 2-4 seconds then mixed to achieve the digestion rate of 80-95%.</p> |
