Hematological Parameters of Boars-Producers at Use of a Natural Mineral Additive in a Diet

Abstract

The aim of the research was to study the morphological and biochemical indicators of the blood of boars-producers using in the diet of a natural mineral additive-bischofite of the Volgograd field. To conduct scientific and economic experience, four groups of boars-producers of 5 animals each were formed. In the experiment, boars-producers of the control group received the main diet, and I, II and III experimental groups – in addition to the main diet, respectively, 5, 8 and 11 ml per animal per day of natural bischofite. Against the background of scientific and economic experience, studies were carried out to study hematological parameters in experimental boars of comparable groups. The results of the research showed that the hematological parameters in the boars of the producers of the compared groups were within the physiological norm and characterized the normal activity of all organs and systems. Compared with animals of the control group, at the end of the main period, after testing the blood of the boars of the experimental groups, the number of erythrocytes was higher by 2.77-6.77%, hemoglobin - by 0.80-2.95%, and the total protein content in blood serum was higher by 0.87-1.57%, albumin by 2.44-6.50% . The boars of the experimental groups exceeded the albumin-globulin coefficient of the animals of the control group by 2.56-8.97%. The content of inorganic magnesium in the blood serum of the boars-producers of the experimental groups, compared with the control, was 0.14 more; 0.20 and 0.24 mmol / L. According to the results on the productive qualities of boars, the introduction of natural bischofite into the diets contributed to an increase in ejaculate volume by 5.0-7.81%; increased sperm cell concentration in 1 ml of sperm - by 2.79-5.12%, sperm activity - by 2.27-6.82%, in comparison with the control. The use of bischofite in the diet of boars, in comparison with the control, contributed to the economic effect due to the cost of additional sperm production - 14080.0 - 22848.0 rubles. At the same time, the best results in terms of hematological and productive indicators of boars-producers, economic efficiency were achieved when bischofite was included in the diet at a dose of 8 ml per boar per day.
