Feed additive for improving energy intake level of beef cattle after delivery

Abstract

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.

[0001] The invention relates to a feed additive for improving the energy intake level of beef cattle. Background technique

[0002] Energy is the first nutritional requirement for beef cattle growth, and it is also the basis for all life activities. The level of energy intake will directly affect the fattening speed and economic benefits of beef cattle. The lack of body energy intake caused by loss of appetite and reduced feed dry matter intake is common in beef cattle production. The physiological characteristics of beef cattle in this period are: after childbirth and blood loss, the body's resistance and digestive function are weakened, and the birth canal Unrecovered, udder edema, mammary gland and circulatory system functions have not returned to normal, especially poor appetite, resulting in lower feed dry matter intake than the normal level before birth, and beef cattle after delivery to meet the energy required for calf lactation, The body will consum...
