Adaptogenic effect of plants and plant compositions when used in feeding cows in addition to the main diet

The article presents the results of using two methods to increase the level of adaptation processes and increase milk the industrial complex. In connection with this goal, a study of adaptation processes in terms of metabolic status and milk productivity in cows during the winter stall period was conducted using two proposed methods.The first method is to add hawthorn fruits to the basic diet at a dose of 20 grams per head. The second method is to use a plant composition of mountain ash and pine needles in a ratio of 20:50 g, which totals 70 g. The experiment was conducted at the Streletskaya Experimental Station, a branch of the Federal State Budgetary Scientific Institution Federal Scientific Center for Legumes and Cereals. As objective indicators of the adaptogenic effect of the plants proposed by the authors, homeostatic blood parameters were studied: physiological and biochemical, as well as milk productivity. The authors found that before the start of the experiment, without the additional use of plant adaptogens, the values of erythrocytes and hemoglobin were below the lower limit of the physiological norm in cows, although the values of other indicators were not in the optimal value. The deviation from the reference values was also revealed in the indicators of their biochemical status, the most important of which for the assessment of adaptation processes were indicators of the oxidant and antioxidant systems. Dairy productivity is a reliable indicator of the growth of adaptive abilities of highly productive cows. When using hawthorn as an adaptogen (the first method), the average daily milk yield increased by 2.51 kg by the end of the experiment. When using the second method using a composition of mountain ash and needles in feeding, the average daily milk yield of Holstein cows increased by 2.35 kg during the winter stall period. An analysis of the results of an experiment to identify the effect of hawthorn (the first method) and plant composition (the second method) on adaptive processes determined by morphological parameters, the state of the oxidant-antioxidant system and milk productivity in Holstein cows during the winter stall period showed the positive effect of using both methods to achieve the goals set.
