Urea in cow's milk is the norm. It is a mistake to assume that its presence in decanted milk signals about problems in your animal. It is important to monitor its level, avoiding an overabundance that can cause diseases of the internal organs of the female cow. In our article we will talk about how to control this process and not cause harm to health.
Should there be urea in milk?
To begin, let's try to figure out what urea is and whether it should be scared of this term. The excreted urea is the end product of protein metabolism in mammals. If it is not allocated the proper amount on its own, then the animal will be additionally fed it. Visually, it is a large-tonnage product produced by small granules. In other words - this is a kind of bait for the animal, containing about 46% nitrogen, which is not a pathology.
Since the fifties of the twentieth century on the territory of Russia began the use of urea as feed for livestock. In the rumen of cows, it turns into ammonia, from which microbial protein is subsequently formed. The volumes of the rumen of the cow are large enough and can reach about a hundred liters. Urea significantly increases the percentage of productivity and regulates the water balance of the body.
How does this affect the quality of the product?
Urea is excreted with the help of kidneys and sweat glands, therefore its presence in milk is quite natural. Urea-containing milk is suitable for use and does not contain elements detrimental to human microflora.
However, a surplus of carbamide adversely affects the work of the liver of the cow and can cause death. To increase the usefulness of milk and dairy products, it is recommended to regularly monitor that the urea level is within the normal range.
Rising and lowering the norm
According to the presence of urea in cow's milk, specialists determine the level of proteins available in the animal. If the urea content is below 15 milligrams per 100 milliliters of milk, then this is a clear symptom of nitrogen and cheese protein deficiency, and indicators of 30-35 mg indicate a surplus.
The optimal amount of cow's milk urea is about 25 milligrams per 100 milliliters of milk. To control this important parameter and make the right diet, it is recommended to regularly analyze the nitrogen content of the milk. Systematic monitoring of the level of urea helps to calculate the proportion of essential proteins in the food complex and protects against performance problems of cows.
Testing is recommended in certain periods when the risk of failure is especially predictable:
- five days after calving;
- thirty days after calving;
- before the mating process;
- before launch.
The most convenient and high-quality way to get results is a rapid test. To determine the level of urea cows, you need to add a few drops of milk to the area with the reagent. After ninety seconds, a color tone will appear that needs to be compared with the attached scale from the set.
It is important to know that the additional use of urea is determined by the energy level of the cow. If a cow receives enough nutrients through protein intake through cultures, then the supplemental consumption of urea is not mandatory.
If the productivity of your cow is low, and the bull needs feeding, then pay attention to the correct amount of urea produced. The dose is about 50-100 grams per day per cow. Detailed calculated after passing the analysis. With an increase in the rate of urea, its consumption decreases or is canceled altogether, and when it decreases, it increases.
