The Influence Of Mildronate On Morphology Of Boars Testes After Reaching The Breeding Preparedness

The aim of the study was to estimate the influence of preparation Mildronate (Quaterin, Meldonium) on morphology of boars, testes after reaching the breeding preparedness. Mildronate was developed by the Institute of Organic Synthesis of Latvian Academy of Sciences. Two groups (control and experimental) of boars were used to achieve the task of the research. Each group of 6 animals where kept and fed at the same circumstances. Preparatory period lasted from weaning (21-28 day) until they reached the puberty and then the training of boars for collection of semen was started. Experimental period started two month later when the boars had reached the breeding preparedness. The boars of experimental group daily got orally 2,0 g of Mildronate 60 days. Animals both control and experimental groups on a regular basis were tested for health status as well as the blood and semen samples where taken. At the end of the experiment both groups of boars were euthanized following the study of testes (mass, volume) as well as histological research.Analysis of studies showed in boar's testes of the experimental group there was tendency of increase of testes mass and volume. Histological studies showed an increase the thickness of spermatogeny epithelium and considerably more interstitial glandulocytes (Leydig cells) in comparison with the animals of the control group.
