Content of fatty acids in erythrocytes of blood of cows before and after calving and their correction

Abstract

The purpose. To study in erythrocytes of cows of different level of milk productivity the content of fatty acids (FA) in before- and after-postnatal periods in connection with reproductive function and at injection of extract of aloe. Methods. Chromatographic, statistical. Results. At 25 – 30th day before calving the ratio of saturated and nonsaturated FA at more productive cows is less than that at less productive ones. Injection of hypodermically extract of aloe at 25 – 30th day before labors decreases in an organism the content of saturated FA and increases the level of monononsaturated and polynonsaturated FA. At the same time at 5 – 7th day before calving authentically increases the content of linolic, linolenic, eicozatrienic and eicozateraenic (arachidonic) FA and on 10 – 14th day after it — the content of linolic, linolenic, eicozatrienic and eicozateraenic (arachidonic), and docozapentaenic. Conclusions. At action of extract of aloe the content of nonsaturated FA in erythrocytes of cows at 5 – 7th day before calving and on 10 – 14th day after it increases. The content of polynonsaturated FA increases due to acids -3 and --6. Injection of extract of an aloe at 25 – 30th day before calving positively influences puerperal period, restore of high-grade sexual cycles and breeding efficiency.
