Abstract

The article presents data on milk productivity, reproductive function and chemical composition of milk, as well as hematological parameters of blood and rumen liquid in high-yielding Holstein cows of German selection, Ukrainian black-spotted dairy and Ukrainian red-spotted dairy breeds in the first lactation period for feeding them different doses of mixed-ligand complexes of Zinc, Manganese and Cobalt.

It is established that the use of mixed-ligand complexes of Zinc, Manganese and Cobalt in the feed mixture in comparison with their sulfates has a positive effect on milk productivity and reproductive function of cows and the chemical composition of their milk, and feed costs decrease with increasing productivity.

The use of different forms and levels of Zinc, Manganese and Cobalt in the diets of experimental cows affected protein and carbohydrate-fat metabolism and the best results were obtained when using different levels of these trace elements in the feed due to their mixed-ligand complexes.

In the rumen liquid of experimental cows, the pH value increased in the alkaline direction and the difference to the control group was statistically significant. There was also a tendency to increase residual nitrogen compared to control. There was a significant difference in the reduction of ammonia nitrogen in the rumen liquid of cows of experimental groups, which indicates better use and assimilation of crude protein.

The best indicators of milk productivity, chemical composition of milk, reproductive function, blood and rumen liquid were obtained when using mixed-ligand complexes of Zinc, Manganese and Cobalt in the feed mixture when the concentration of these trace elements in 1 kg of DM was, mg: Zinc – 60.8; Manganese – 60.8; Cobalt – 0.78; Selenium – 0.3; Copper – 12 and Iodine – 1.1. This concentration of trace elements was achieved due to their mixed-ligandent complexes, copper – its sulfate, iodine – potassium iodide, selenium – selenium suplex.
