Since the beginning of the year, about 300 thousand milk samples have been examined in laboratories in the Vologda region

There are three laboratories involved in milk analysis in the region. Two of them were created on the basis of the North-Western Research Institute of Dairy and Grassland Farming named after A.S. Emelyanova and one at the Cherepovets Breeding Enterprise.
The laboratories serve farms not only in the Vologda region, but also in the Leningrad, Tver and Novgorod regions. Over 8 months of this year, laboratories examined 281,029 milk samples.
In accordance with the requirements for types of breeding farms, assessment of product quality should be carried out in laboratories for selection control of milk quality.
Analysis of milk quality allows not only to determine the amount of fat and protein in milk , but also shows the health status of the cow.
On milk qualityMany factors influence, but the most important of them are the feeding and maintenance of dairy cows. A constant and well-established metabolism is a necessary condition for udder health.
Feeding errors can cause a variety of health problems in animals (e.g. acidosis, ketosis, mineral metabolism disorders, etc.). As milk production increases, the risk of metabolic disorders also increases.
The fat content in milk characterizes, first of all, whether the necessary structure of the diet is provided (control of the ratio of bulk feed to concentrated feed, the amount of feed eaten). A significant decrease in fat in individual animals of greater than 0.4% between two control milkings and a fat to protein ratio below 1.0 may be indicative of acidosis.
The protein content of milk reflects how well the cow is provided with energy and is a kind of energy barometer for the herd. The level of protein in milk depends on whether the rumen microbes that synthesize microbial protein have enough energy at their disposal. And only with high productivity, protein that is not broken down in the rumen becomes increasingly important. There is a noticeable relationship between animal condition curves and milk protein.
