Influence of feeding cows with plant adaptogens on the physiological and biochemical status of lactating cows

Abstract

Purpose: development of a method for correcting the physiological biochemical status of lactating cows and increasing their productivity in industrial stress conditions using vegetable adaptogens based on the sea buckthorn, hawthorn and lecithin.Materials and methods. The work reflects the results of a study on the effect of phytocompositions, including the fruits of sea buckthorn (SB), blood-red hawthorn (BH) and vegetable lecithin (L), on the physiological and biochemical status and productivity of lactating cows. The following groups of animals were formed, 5 animals each (n = 5), duration 30 days: group 1 (control) received only the basic diet of the farm (BD); Group 2 (BD + SB + BH) - the main diet of the farm, sea buckthorn fruits at a dose of 130 g / cow / day, blood-red hawthorn fruits dried at a dose of 40 g / cow/ day; Group 3 (BD + SB + BH + L) - the main diet of the farm, sea buckthorn fruits at a dose of 130 g / cow / day, blood-red hawthorn fruits dried at a dose of 40 g / cow / day, lecithin at a dose of 70 g / cow / day Revealed a positive effect on the indicators of protein, carbohydrate, lipid metabolism and milk productivity. By the end of the experiment, the experimental cows had the highest average daily milk yield in cows of group №. 3 that received, in addition to the main diet, a composition of hawthorn, sea buckthorn and vegetable lecithin (5.5% higher relative to the control group) and in group of cows №. 2 that received composition from the fruits of hawthorn and sea buckthorn (an increase of 4%).Results. Revealed positive effect on indicators of protein, carbohydrate, lipid exchanges and dairy productivity. By the end of the experiment, the experimental cows are the largest average daily fishing of the group of group No. 3, which additionally received the main diet from the fruits of hawthorn, sea buckthorn and vegetable lecithin (above 5.5% relative to the control group) and in the group of cows No. 2, which received the composition Of the fruits of hawthorn and sea buckthorn (the increase was 4%).Conclusion. The analysis of the results of the study of biochemical indicators shows that the composition comprising the fruits of sea buckthorn, hawthorn blood-red and vegetable lecithin has the greatest adaptogenic properties.
