Problems solved by technology

Although the early weaning technology of dairy cows has begun to be implemented in foreign countries and some large-scale dairy farms in China, my country is still in its infancy, and the level of feeding and management cannot keep up with the need for directional cultivation of the rumen, and there is a lack of research on anti-stress intervention technology during the weaning period. Sources of weaning stress in calves still not well understood
Especially in the special physiological stage of calf weaning, there is a lack of research on the digestive characteristics, blood index changes, and the mechanism of relieving oxidative stress to improve the antioxidant status of calves. A lot of basic research is needed to further improve the breeding technology of calves

Embodiment 1

[0021] A calf early weaning accelerator (hereinafter referred to as the combined accelerator), based on the weight of the added concentrate as 100%, consists of the following components: vitamin E 0.006%; Ethoxyquinoline) 0.02%; Propyl gallate (PG) 0.001%; ​​Rumen-passed DL methionine 0.4%. When the accelerator is used, it is added to the fine material.

Embodiment 2

[0023] A calf early weaning accelerator (hereinafter referred to as the combined accelerator), based on the weight of the concentrate as 100%, includes: vitamin E 0.006%; Aikedo (U.S. Novus Corporation, the active ingredient is ethoxyquinoline ) 0.02%; propyl gallate (PG) 0.001%; ​​rumen-passed DL methionine (plays a synergistic role, has the supplementary effect of chelating metal ions, anti-oxidation and providing organic acids) 0.4%. When the accelerator is used, it is added to the fine material.

Embodiment 3

[0025] A calf early weaning accelerator (hereinafter referred to as the combined accelerator), based on the weight of the concentrate as 100%, includes: vitamin E 0.006%; Aikedo (U.S. Novus Corporation, the active ingredient is ethoxyquinoline ) 0.02%; propyl gallate (PG) 0.001%; ​​rumen-passed DL methionine (plays a synergistic role, has the supplementary effect of chelating metal ions, anti-oxidation and providing organic acids) 0.4%.

Abstract

The invention relates to a feed additive, in particular to an early weaningaccelerant and a feeding method fora young ruminant. The early weaningaccelerant for the young ruminant is prepared from, by weight 100% of concentrated feed to be added, 0.003-0.02% of vitamin E,0.006-0.03% of ethoxyquinoline,0.0005-0.005% of propylgallate and 0.05-0.5% of rumen DL methionine. The total antioxidant capacity of the ruminant can be improved by using the accelerant, peroxideproduction is decreased, the young ruminant can well resist the stress brought by weaning, especially the untoward effect caused by free radicaloxidization, the pH value in the rumen is stabilized from 6.4 to 6.6, the development of rumen epithelium can be promoted, and the diarrhea occurrence rate can be reduced by 10-30%.

Description

technical field [0001] The invention relates to a feed additive, in particular to an early weaning accelerator for young ruminants and a feeding method thereof. Background technique [0002] During the weaning process of calves, along with changes in feed form, nutrient source and feeding environment, the calves have a certain stress response. The digestive system and immune organs of early weaned calves are not yet fully developed, and their functions are not yet perfect. Stress symptoms such as growth stagnation and diarrhea are prone to occur during the weaning period. [0003] Calf feed contains high fat and is easily oxidized, and the body’s redox balance is broken during early weaning, free radicals increase, and antioxidant capacity decreases, resulting in severe oxidative stress. Although the early weaning technology of dairy cows has begun to be implemented in foreign countries and some large-scale dairy farms in China, my country is still in its infancy, and the l...
