The invention relates to a
feed additive for improving the energy intake level of
beef cattle after delivery, and aims to solve the current problems of abnormal
rumen fermentation, low crude
fiber digestibility and easy ruminal
acidosis when the energy intake level of the
beef cattle after delivery is improved by greatly increasing the concentrate feed ratio in a daily ration. The
feed additive is prepared from
astragalus, pilose asiabell root, licorice, uniflower swisscentaury root, Chinese angelica,
leonurus,
acorn kernel
meal, dried orange peels, mint,
dandelion, parslane
herb and shizandra
berry which are dried, crushed and screened. The
feed additive is added into a concentrated feed of the
beef cattle after delivery and can be directly fed. The feed additive can improve the crude
fiber digestibility while improving the energy intake level, does not influence the
rumen fermentation, avoids the happening of the ruminal
acidosis, and has the characteristics of convenient operation, high safety, easily available sources, low cost and the like.
