PRODUCTIVITY OF DAIRY COWS WITH THE PARAMETERS OF THE FEEDING DIET

Abstract

Dairy productivity of dairy cows is related to the nutritional parameters of feeding diets. The nutritional value of feeding diets and dairy cows can be
increased with zeolite feed additives. In scientific and economic experience, a zeolite-chlorellal premix was added to the feeding diets of dairy cows, which
increased the mineral and vitamin nutritional value of the diet, due to the selectively absorbed and ion-exchange qualities of zeolites, which directly affected
microbiological processes in the rumen. The pH shift of the rumen chyme fluid from 6.14 to 6.17 contributed to the development of the microecosystem, which
led to an increase in the number of infusoria - by 41.1 thousand /ml, the volume of volatile fatty acids – by 0.79 mМmol/100ml, compared with the control group.
Thanks to the selective adsorption of ammonia zeolite crystals, the synthesis of valuable microbial protein increased by 7.3%, the consumption of the dry matter of
the diet - by 0.6 ± 0.03 kg, the daily milk yield - by 0.8 ± 0.04 kg. An increase in the content of proteins in milk - by 0.13%, fats - by 0.16% led to an overestimation
of the degree of conversion of dry matter consumed by cows, metabolic energy and feed protein. Correlation analysis has derived regression equations for the
relationship of dairy productivity of cows with nutritional parameters of the feeding diet.
