Comparative efficacy of water-soluble feed additives «Reasil HumicVet» and «Silymarin nSePs» on changes in blood parameters of roosters

Introduction. Often the reason for the premature culling of roosters is a decrease in the fertilizing ability of their sperm as a result of increased exploitation. The available data obtained during the study allow us to state the need for the use of water-soluble liquid feed additives to maintain high rates of sexual activity in roosters. The purpose of the study is to study the comparative effectiveness of using water-soluble feed additives “Rasil Humic Vet” and “Silymarin nSePs” on changes in blood parameters in roosters.

Object. The experiment used roosters of the HISEX brown cross.

Materials and methods. The selected roosters were divided into three groups: group 1 (n=5) – control; The 2nd group (n=5) experimental group received “Reasil Humic Vet” with water, the 3rd group (n=5) experimental group received “Silymarin nSePs” with water. It has been established that drinking the liquid feed additive “Reasil Humic Vet” and the product “Silymarin nSePs” with water neutralizes the negative “technological” stress effect on the body of breeding roosters.

Results and conclusions. It was established that the variability and level of biochemical parameters of blood plasma in roosters of the 1st control group were significantly higher in the content of triglycerides, cholesterol, cortisol and corticosterone, in comparison with experimental breeding roosters, which indicates the stress of this group. The use of biologically active additives "Reasil Humic Vet" and Silymarin nSePs for breeding roosters helps to reduce the level of concentration of the hormone corticosterone in the blood serum of experimental animals by 33.47% and 34.9% relative to control ones. At the same time, the use of these dietary supplements stimulates hematopoiesis, which is reliably stated. At the same time, the use of these biologically active additives stimulates hematopoiesis, as evidenced by significantly higher numbers of red blood cells and hemoglobin concentration in the blood of experimental animals relative to control roosters. In the experimental groups, there was a significant increase in lacto- and bifidobacteria with a simultaneous decrease in the number of coliform bacteria, enterococci and staphylococci. The materials presented in the article describe a solution to the problem of maintaining reproductive health through the use of liquid watersoluble feed additives "Reasil Humic Vet", consisting of a solution of high molecular weight sodium salts of humic acids from leonardite and the product "Silymarin nSePs", containing colloidal selenium and silymarin as nanoparticles and stabilizer.
