Abstract
Relevance. During the milking period, high-yielding cows mobilize body reserves, and the metabolism of new cows is precisely coordinated to meet the increased metabolic demands for milk synthesis.
The aim of the experiment was to study the effect of increased feeding level on the component composition of milk.
Methods. The studies were conducted in the breeding farm of the Moscow region JSC “NaroOsanovsky” on first-calf cows, the duration of the experiment — 120 days. The groups (11 goals each) were formed according to the principle of pairs of analogues. The basic diet of the control group was balanced in all nutrients, minerals and vitamins. Feeding level of first heifers of the 1st and 2nd experimental groups from the first days of lactation was increased by additional inclusion of targeted protein-vitamin-mineral concentrate (PVMC). Milk samples were taken during control milkings with registration of daily milk yield. The component composition of milk was determined using an infrared automatic milk analyzer “CombiFoss FT+” (Denmark) in the laboratory of selection control of milk quality of JSC “Moskovskoye” for breeding work. In the average samples were determined milk fat, protein, lactose, dry matter, skim dry matter, urea.
Result. During the period of the experiment, the average daily milk yield of experimental cows was significantly higher compared to the control. The analysis of milk component composition indicates that due to the increased level of feeding, milk of cows of experimental groups was characterized by a higher nutritional value.
