First, anti-stress agent stress refers to the cow's emergency response to transportation, immunity, high temperature, humidity, cold, calving, lactation and other adverse stimuli made. High-yielding cows are sensitive to stress such as high temperatures, cold, childbirth, and lactation. Therefore, prior to the above-mentioned situation, the contents of trace elements manganese, iron, copper, zinc, iodine, and cobalt that have anti-stress effects in the diet should be increased by approximately one-fold compared with the normal level, which can effectively enhance the resistance of high-yielding dairy cows. Exciting ability.

Second, the buffering high-yield dairy cows in the entire lactation period concentrate feed intake are relatively large, so need to add appropriate amount of baking soda, magnesium oxide and other buffers in order to improve the high-yield dairy cows intake, milk production And milk ingredients, to maintain the health of cows, reduce the occurrence of rumen poisoning, regulate and improve the effect of rumen microbial fermentation. 1 baking soda. High-yielding dairy cows are fed with baking soda during the prolific lactation period, which has a significant effect on the prevention of metabolic diseases such as diabetes and rumen poisoning. In particular, it is better to feed silage and high concentrates all year round. Feeding method: After the calving of dairy cows, start the supplementary feeding, until the end of the lactation period, the amount of supplement is 1.5% to 2% of the concentrate amount, that is, 150 to 200 grams of baking soda is mixed into every 10 kilograms of the material, and do not feed . 2 magnesium oxide. According to the weight of dietary dry matter 0.2% ~ 0.4% or 0.3% ~ 0.6% of the amount of concentrate to add. It is also possible to use 2 to 3 parts of sodium bicarbonate and 1 part of magnesium oxide to mix, and add 0.6 to 0.8% of the dry matter of the diet or 1.6% to 2.6% of the amount of the concentrate.

III. Ectopic Acids The addition of 1% iso-acid additives to high-yield dairy cows can significantly increase milk production, and increase milk fat percentage and feed conversion efficiency. Such substances mainly include isovaleric acid, isobutyric acid and isohexanoic acid.

Fourth, propylene glycol in the high-yield dairy cows dietary supplemented or directly fed propylene glycol substances, such as propylene glycol, ethylene propylene glycol, isopropylene glycol, etc., can effectively reduce and prevent the occurrence of ketosis.

Fifth, rare earth in the dairy cow concentrate to add 40 to 45 mg of rare earth, cows can increase the daily milk production by 11% to 15%, while improving milk fat rate, enhance the disease resistance of dairy cows to prevent gastro-intestinal diseases.

6. Zeolite Zeolite is boiling when it is heated at high temperature, so it is called zeolite. For dairy cows, zeolites can adsorb harmful gases in the gastrointestinal tract and slowly release the adsorbed ammonia ions to synthesize bacterial proteins in the rumen, increasing protein production and deposition in the carcasses. In addition, zeolites enhance the body's enzymes and increase the utilization of crude fiber by rumen microbes. Adding 4% to 7% of the zeolite in the concentrate of cows can increase the amount of milk by about 8%.
