2. Eliminate the use of bull (semen) breeding that has not been determined by progeny; resolutely do not use “wild†bulls without pedigree and no breed licenses to avoid lowering the milk production performance and milk quality of future generations.
3. In view of the poor quality of milk produced by their own cows, bulls with good milk quality should be selected for improvement so that the quality of future milk production can be improved.
Control the ratio of refined roughage in the diet
Milk contains various nutrients such as fat, protein, sugar, minerals and vitamins. Most of the milk is synthesized in the breast by various precursors selected from the blood, such as 90% of protein in milk. The precursor in the feed is synthesized in the mammary gland and 10% of the protein is carried directly by the blood. Therefore, if the precursors are insufficient, the normal composition of the milk content and the milk component cannot be ensured, and if too much of the precursor is used before, it will cause waste. Milk content generally fluctuates with production and dietary nutrient levels. The ratio of fines to coarses is roughly 50:50 (range 60:40 to 40:60), which is the proportion of feed that gives the highest milk composition. During the peak period of lactation, the nutrient requirement of dairy cows becomes larger, and the quality and feed structure of the diet should be fully guaranteed. When the quality is poor or the structure is not good, protein deficiency is often caused. When the amount of protein is insufficient, the amount of milk will decrease, the milk protein rate will decrease, and the milk will become thinner. In order to increase the energy of the diet, high-quality roughage should be fed while increasing the concentrate feed.
Fully guarantee the quality of roughage
Practice has proved that high-quality alfalfa hay can improve milk production per head from 800 kg to 1200 kg, while high quality roughage can increase milk fat percentage by 0.1% to 0.2%, increase milk protein rate by 0.03% to 0.06%, and increase lactose by 0.02%. 0.04%, improve non-fat solids 0.05% ~ 0.09%. Low-quality roughages prevent high-yielding dairy cows from exerting high-yielding potential, deteriorate their physical quality, and reduce the quality of their milk, failing to meet the requirements for dairy processing, and directly reducing economic returns. For poor quality roughage, its nutritional value can be increased through physical, chemical, and microbial treatments. The improvement of the quality of roughage can increase the dry matter intake of dairy cows, optimize the ruminal environment of dairy cows, improve the digestion and metabolism of nutrients in the body, and achieve the best use of roughage for dairy cows. Ultimately, it can reduce production costs, improve milk quality and raise cattle efficiency the goal of.
Pay attention to strengthening the sunstroke prevention measures for dairy cows
The optimum temperature for dairy cows is 10°C~16°C, and it has the characteristics of cold-heat and heat-resistance, especially Holstein cows are even more resistant to heat. To this end, summer should pay attention to doing a good job:
1. Adjust rations and strengthen management. Increase the energy concentration of the diet so that cows increase feed intake. Appropriately increase the amount of grain fed, add calcium fatty acid, and increase the palatability of succulent green feed, tubers, melons and so on. Feed it once at night or in the early morning when the climate is cool. Increase drinking water and reduce the number of cows to facilitate heat dissipation. Change the concentrate powder into granules to improve the digestion and absorption of the concentrate.
2. Increase ventilation and spray cooling.
3. Greening environment. Around the barn, around the playground must be green, not only beautify the environment, but also play a role in shading.

Function:
1.Monobenzone is a compound used as a topical drug for medical depigmentation.
2.The topical application of monobenzone powder in animals decreases the excretion of melanin from melanocytes. The same action is thought to be responsible for the depigmenting effect of the drug in humans.
3.Monobenzone may cause destruction of melanocytes and permanent depigmentation.
4.The histology of the skin after depigmentation with topical monobenzone powder is the same as that seen in vitiligo.
5.The epidermis is normal except for the absence of identifiable melanocytes.
