Аdditional information on the analysis of feed and milk

Regular analysis of the content in milk of fat, protein, urea, ketone bodies and somatic cells makes it possible to obtain the necessary information about the state of animal health and systematically improve it in the long term.

The composition of milk and its quality are influenced by many factors, but still the most important of them are the feeding and maintenance of dairy cows.

Improper feeding can cause many health problems in animals (acidosis, ketosis, etc.). With an increase in milk production, the risks of metabolic disorders increase. However, this does not mean that highly productive cows are sick more often than animals with low productivity. High milk yields only mean that feeding should be based on accurate calculation of the diet, as well as monitoring and analyzing the most important indicators of productivity.

The content of fat, protein, urea, ketone bodies and somatic cells, as well as the amount of milk produced, are indicators that must be constantly monitored for successful dairy farming.

Each dairy company can receive these indicators on the basis of monthly test milkings.

Principles of Analysis

The principles of analysis of the level of protein feeding and the health of dairy cows in terms of milk composition:

  • The analysis of the composition of milk is carried out on individual samples from each cow, obtained during the test-call once a month;
  • Analysis of the composition of milk is carried out in the context of the whole herd or by productivity groups (<100 days, 100-200 days,> 200 days of lactation);
  • The results of the study are analyzed after statistical processing, as the indicators of the composition of milk are different for each animal.

Milk analysis method The branch “Research and Innovation Center for Animal Husbandry” analyzes the composition of milk and the counting of somatic cells on modern high-performance infrared analyzers MilkoScanFT + and FossomaticFC, providing the possibility of conducting an early diagnosis of mastitis, ketosis, determining the level of protein feeding 

Early diagnosis of mastitis

The counting of somatic cells in milk using FossomaticFC equipment provides important information about the health status of the udder of dairy herd cows.

Mastitis is a costly disease for the dairy industry, leading to additional costs for veterinary care, the purchase of antibiotics, a decrease in milk yield, a decrease in profits, a loss of quality, and culling the number of somatic cells in thousand units

 Figure – Milk loss in kg per head / year

 Regular monitoring of somatic cells helps to avoid undesirable loss of milk caused by mastitis.

Somatic cells are white blood cells (leukocytes)and cells of the secretory tissue of the udder (epithelial cells), allowing to eliminate infection and restore tissue damaged by bacteria.The number of somatic cells in a healthy breast is insignificant.However, in the event of infection or injury of the udder, the body begins to secrete a significant number of somatic cells in the lesion. Therefore, the number of somatic cells is a recognized indicator of breast health and milk quality. Mastitis can be clinical(the number of somatic cells > 1 million) or subclinical (the content of somatic cells from 200 000 (the maximum permissible content to 1 million)

Why do you need to do analysis of urea in milk?

Information on urea content in milk is of particular value to farmers in determining the optimal diet and providing the necessary level of protein in the feed mixture.

The cow should be fed with the appropriate content of protein for maximum milk production.However, the amount of protein exceeding the needs of the animal, no longer increases milk production, but entails additional costs

Together with the fat/protein ratio in milk, urea content indicates whether the right balance between energy and protein is achieved

Insufficient energy value of feed can cause ketosis in cows in the early stages of lactation, and high levels of urea are toxic to sperm and embryos and can lead to infertility and the need for re-insemination of animals.Urea levels also help to monitor the environmental impact on the dairy herd through the release of nitrogen in the urin

 In modern conditions of the maintenance at highly productive dairy cows quite often there is a problem of violation of a protein metabolism that can act as the reason of decrease in dairy productivity, indicators of reproduction, emergence of various diseases and, as a result, early departure of an animal.

  For the timely detection of such violations, it is recommended to monitor the content of urea in the blood or milk of cows. Urea, among its other functions, plays a major role in animal metabolism as a carrier of spent nitrogen. Any deviation of the level of urea concentration from the norm can lead to various disorders, such as: reduced productivity, the occurrence of liver diseases, reproductive disorders, etc.  The level of urea concentration provides useful information about the effectiveness of animal metabolism — it may indicate a lack or excess of protein intake. Therefore, constant monitoring of urea concentration allows manufacturers to control the balance of diets in terms of energy-protein ratio and prevent financial losses in the future.

  A high level of urea concentration can cause functional disorders of the digestive process due to lack of energy required for fermentation. The process of cleavage in the rumen of proteins on the one hand and carbohydrates on the other, can also be disrupted. More excess urea can reduce the quality of milk intended for the production of cheese

        Low urea content in milk, in turn, can cause a decrease in productivity, as well as problems with fertility of animals.

Ketosis

Ketosis of cattle brings to farms big losses as a result of decrease in dairy productivity by 50-70%, reduction of terms of use of animals to 3-4 years, violations of reproductive function, weight loss by animals. Ketone substances, penetrating through the placenta, cause abortion, stillbirth, and born calves with signs of General weakness are easily and quickly exposed to various diseases.

Ketosis in practice is diagnosed only in the clinical stage — to reduce feed intake, change the behavior of animals, the fullness of the scar.

Branch “Scientific and innovative center of animal husbandry” LLP “Kazniizhik” available equipment allows for early diagnosis of subclinical ketosis on the level of ketone bodies in milk. Beta-hydroxybutyrate (VNV) or Beta-hydroxybutyric acid is one of the main components of ketone bodies formed during ketosis. Its elevated level in milk is a reliable indicator of energy imbalance (Geishauser, 1998).
