1)Dairy breeding technicians should pay attention to not drinking domestic wastewater.
There are two kinds of domestic wastewater. They should be treated differently. For some rice-washing water, noodle soup, dumpling soup, vegetable soup and so on, as long as they are not sour, they can directly let dairy cows drink. For the washing water of household laundry, dishes, seafood, and dishwasher, especially meat washing water, cows should not be allowed to drink casually.
2)Dairy cow breeding technicians should not let cow drink distillation pot water.
For example, steamed bread water, after boiling for a long time, oxygen gradually evaporates with water vapor, but heavy metals, nitrates, sulfate ions, and other harmful components are not easy to evaporate. If often given to cows to drink, cows will appear blood pressure reduction, anemia, leading to circulatory browning and affecting the production performance of dairy cows.
3)Dairy cow breeding technicians should pay attention not to let cows drink slops.
Slops are the waste leftover from restaurants, hotels, and canteens. It contains numerous viral pathogens and has high salinity. It is easy for cows to cause infectious diseases and salt poisoning. Without drinking the polluted river, although it is running water, pathogenic microorganisms are not easy to reproduce, they can still survive. Farmers along the river often dump some domestic refuse into the river. When it rains, some animal manure washes into the river along with the rain. Some farmers also throw sick and dead animals into the river at will. Dairy cows drinking this water are highly susceptible to disease.
4)Dairy cow breeding technicians should pay attention not to let cows drink ice sludge water.
Directly to feed ice sludge water to cows, which will affect the health of cows, lead to abortion of pregnant cows, calves cold, diarrhea, dysentery, and other diseases. If you want to feed it, you can warm it properly or mix it with hot boiled water.
5)Dairy cow breeding technicians should pay attention not to let cows drink the wastewater produced in industrial.
Wastewater produced in industrial production, even if it looks clean and bright with the naked eye, often contains harmful ingredients that exceed the standard seriously. After drinking, mild ones affect growth and development, and heavy ones cause poisoning.
6)No drinking wastewater from the processing of agricultural by-products.
There are more oil and water in the wastewater produced in the processing of meat processing plants, pickle plants, and beancurd mill. Dairy farmers often think that feeding dairy cows with this kind of water can improve milk production. Little know that because this wastewater contains numerous pathogenic microorganisms and some uncertain chemical substances, it is easy to cause infectious diseases, parasitic diseases, and poisoning, etc. Cows should not be allowed to drink.
7）Dairy farming technicians should be careful not to let cows drink paddy water and other field water.
When grazing dairy cows, some people let them drink paddy water or other rainwater accumulated by the edge of the field, which often contains pathogenic microorganisms, pesticides residue, fertilizers and so on. After drinking, dairy cows are prone to parasitic diseases and even poisoning. There are also pond water and trench water, which do not flow or flow slowly. Because of long-term storage, pathogenic microorganisms and parasites are multiplied in large quantities. Dairy cows are susceptible to various infectious diseases and parasitic diseases after drinking. Moreover, because many farmers wash medicine bottles and spray medicine buckets in ponds and gullies in summer, the water here is polluted by pesticides, and cows are prone to poisoning after drinking.
8) Dairy cow breeding technicians should pay attention not to let cows drink untreated well water.
Close to chemical factories, paper mills and dyeing and weaving factories, the groundwater is easily polluted by pollutants from factories, which makes iron, lead, mercury, chlorine, fluorine, and other toxic and harmful substances seriously exceed the standard, thus causing chronic poisoning of dairy cows. Therefore, in the suburban farms where factories are relatively dense, it is better to send the relevant departments for testing before using well water. Cows can only be drunk if it meets the drinking water standard.
