1 Does feeding cows soy husks really improve milk production in dairy cows?
Because the main component of soybean husk is cell wall or plant fiber, it cannot be well digested and absorbed by monogastric animals such as pigs and chickens, but it can be used by ruminants through the action of rumen microorganisms. Replacing some of the concentrates in the diet with soybean husks can reduce the occurrence of metabolic diseases such as acidosis and increase the degradation rate of fiber in the diet.
According to the experiment, the milk yield of dairy cows did not change when soybean husk replaced 30% of the corn in the dairy cow's diet, which indicated that it was feasible to replace corn with a certain proportion of soybean husk in terms of nutritional value. When soybean husks are used instead of 30% corn in the cow's diet, the milk fat percentage of the cow will be significantly improved.
Therefore, the use of soybean husk to replace part of the energy concentrate in dairy cow production has a good effect on improving the economic benefits of dairy cow feeding.
From the above information, we should use soybean husks to feed dairy cows in those places where the climate is uncertain and the feed resources are not very abundant, which can solve the problem of milk production. Recommended by Rural Network China.

Yes, I have done comparative experiments in different dairy farms and dairy cow communities, the selection of milk is close, other conditions remain the same, the cows with lactation days around 100 days are divided into 2 groups, the experimental group uses soybean husk and beet pellet meal mixed product kilograms, the control group does not use, the result is that after 7 days, the average yield of dairy cows in the experimental group is higher than that of the control group, very good feed, I don't know if you are **, if it is around Hohhot, Yili feed company has a fiber material is very good to try.

A lot of them can be learned from the China Dairy Association or the Chinese dairy industry system.

Heat stress in dairy cows seriously affects the performance of dairy cows, and measures such as blowing, intermittent watering, and changing the diet formula can alleviate heat stress and improve milk production.
In dairy farms, the use of fan blowing is more extensive and has a good effect, but it is not ideal in special high temperatures. When the air temperature reaches 32 and the relative humidity is 80%, or the air temperature is 36 and the relative humidity is 65%, the body temperature of the cow will still rise even if the wind blows at a speed of meters and seconds. Choosing the method of blowing air combined with intermittent watering can increase the amount of evaporative heat dissipation, avoid the rise of the cow's body temperature, and thus increase milk production.
Be careful, however, to start watering the cows only when the temperature exceeds 27 or more.
Change the diet recipe. During high temperatures, cows reduce feed intake to maintain balance, which is the main reason for the decline in milk production. Increasing the crude protein content of the diet from 16% to about 21% can increase milk production by 7% to 9%.
In this way, even if the cow's feed intake decreases, the total protein intake can be guaranteed to be not reduced, compensating for the loss of enhanced protein breakdown during heat stress.
Increase the amount of water you drink and lower the temperature of your water intake. In summer, the salt content in the dairy cow's diet can increase the daily water intake of each cow by about 10 kilograms. Giving cows deep well water can also relieve heat stress.
Potassium supplementation for cows. In the summer high temperature season, each cow is fed 180 grams of potassium chloride every day, the water intake of the cow can be improved, the feed intake is significantly increased, the rectal temperature is slightly reduced, the respiratory rate is significantly slowed down, and the milk yield of the cow is significantly improved, which is a better method of resisting heat stress at present.

1) If the pH is too low, the spatial structure of the related enzymes will be destroyed and the enzymes will be inactivated; In order to get rid of excessive acidic substances, alkaline substances can be added to the feed to neutralize the acidic substances and maintain pH stability The internal environment is a liquid environment composed of extracellular fluid, mainly including plasma, tissue fluid and lymph
2) when frightened, the secretion of adrenaline increases, the process is neuromodulation; At the same time, adrenaline plays a role, regulating vital activities belongs to hormonal regulation
Therefore, the answer is: 1) the pH is too low, which leads to the destruction of the spatial structure of the related enzymes and the inactivation of the enzymes; Neutralization; a liquid environment composed of extracellular fluid; interstitial fluid; lymph (lymph);
2) neuromodulation and hormonal regulation;

1. Dairy cow breeds. 2. Environmental conditions, such as cowshed, sports field, milk parlor environment, feed and other quality. 3. Management technology, including management methods, technical personnel level, etc. 4. Investment purpose. All of the above reasons.
