Abstract
The purpose of research is to study the effect of feeding a complex mineral-vitamin supplement on hematological blood parameters and the productivity of the Romanov breed young ewe. Objectives: to determine the deficiency of minerals in basic feed; taking into account the deficiency, complex mineral and vitamin feed supplement, (hereinafter referred to as CMVFS); establish feeding standards and techniques. To conduct scientific and economic experiments at the State Property Committee Yakupov D.N. of Birsk District of the Republic of Bashkortostan, 4 groups of young ewes of Romanov breeds were selected using the method of pair-analogues (by age, live weight) of 10 heads in each (1 control and three experimental). The duration of the experiment was 120 days. Three recipes for the production of CMVFS were developed with the introduction into their composition of local natural zeolite from the Kaltuban deposit of the Republic of Bashkortostan and sapropel, monocalcium phosphate and premix P81-1-89 and feed sulfur. The control group was fed the main diet; the daily norm of CMVFS was fed to the experimental groups as part of a grain mixture once a day. At the end of the experiment, compared with the indicators of the control group, the number of red blood cells in the experimental groups increased by 1.83 %, 6.39 and 10.16 %; leukocytes – by 4.00 %, 12.79 and 15.61 % and hemoglobin – by 3.00 %, 4.25 and 5.21 %. To assess the state of metabolism in the body of experimental animals using the CMVFS, biochemical blood parameters were studied before the experiment and during removal from the experiment. The additional introduction of CMVFS, which contains natural zeolite and sapropel in various proportions, into the diet of the animals, had a positive effect to varying degrees on the biochemical and hematological parameters of the blood, contributed to the improvement of the clinical condition of the animals, and also had a stimulating effect on protein and carbohydrate metabolism, hematopoietic functions organs and heart. All this creates the prerequisites for increasing animal productivity.
