The objective of this study was to analyse the influence of introducing Schweres Warmblut (SchW) blood on the zoometric features of Silesian breed horses. The research material was pure Silesian breed horses and crossbreeds with the SchW breed, born in the period of 1984–2004. The population was divided into four groups, depending on the contribution of Schweres Warmblut blood (0.0%, 0.1–24.9%, 25.0–49.9% and 50% and more). Differences were determined among groups in the range of values of the three basic characteristics (height at withers, chest and cannon circumferences), build indices (massiveness, boniness and strength), and point-scale estimation. The highest differences between Silesian horses and F1 generation crossbreeds were observed in height at withers (stallions: 161.04 and 165.13 cm, mares: 159.58 and 162.45 cm), massiveness index (stallions:124.56 and 120.19), and point-scale estimation (mares: 77.0 and 79.61 points, respectively). The groups with lower shares of SchW blood were characterized by intermediate values that corresponded more to changes that took place in the Silesian breed over time, than to those resulting from the contribution of SchW blood.

The aim of this study was to establish the physiological ECG values in the Silesian horse and to compare the results with literature data for other breeds of horses. This study was carried out on 31 healthy Silesian horses (15 males and 16 females) aged 2-19 years. The ECG was carried out after an anamnesis and clinical examination and without prior premedication or use of force, both of which could affect the ECG result. The mean heart rate (HR) in the Silesian horses was 39 ± 8.1 beats per minute. In the majority of the leads, P waves were single positive waves. Notched waves were present in 16-51% of the horses, bifid waves were found less frequently, and biphasic P waves were seen least frequently. In the aVR lead, the P wave was most commonly found to be single negative. The PQ interval ranged from 0.18 s in the CV1 lead to 0.29 s in the aVR lead. Most often, the PQ interval lasted 0.24-0.28 s. The QRS duration ranged from 0.079 s in the CV1 lead to 0.099 s in lead III. The QRS duration was between 0.08 and 0.1 s. Generally, the T wave was single positive or negative. It was biphasic only in the precordial leads. Unlike P waves, notched T waves were not found. The ECG parameters in the Silesian horse do not differ from normal ECG values for other horse breeds of similar weight. Specific features of the ECG in the Silesian horse are a frequent occurrence of additional R’ and S’ waves in the Einthoven leads and a relatively long supraventricular conduction time.

Analysis of genetic structure of Silesian horses from National Stud. The aim of the study was to analyze the genetic composition of Silesian horses bred in "Książ" National Stud basing on their pedigreesand to try to answer the following question: is the subdivision of Silesian horse population really necessary to prevent local horse breed? As the material 72 pedigrees of brood mares and stallions, born between 1991 and 2009 were used. On average, 93.1% of animals were inbred, there were 96.55% inbred stallions and 90.70% inbred mares. The mean inbreeding coefficient for all horses was 2.3%, for inbred horses it reached 2.5%. There were more inbred mares (39) than stallions (28). All 72 Silesian horses from "Książ" State Stud were related with the average relationship coefficient of 8.5%. The total and effective number of founders were 458 and 163, respectively. The total andeffective number of ancestors were 64 and 22, respectively. Among the founding breeds Thoroughbred horses predominated, the next were Oldenburg and Silesian horses, whereas among ancestors there were much more Silesian horses than Thorougbreds. All in all, the genetic diversity of the Silesian horses from "Książ" National Stud was satisfactory, however its monitoring is required because of both upward inbreeding and 100% related animals. Because the population of Silesian horses is small, less than 2,000 animals and sligtly over 1,000 animals included in conservation programme, the artifical subdivision of this population as proposed in the new breeding programme, which would result in creation of two subpopulations: “old-type” and “new-type” Silesian horses, is not recommended. For maintaining genetic diversity, it could be also possible to carefully import of semen or stallions of similar breeds, i.e. German Alt-Oldenburger horses or German Heavy Warmblood horses. The plan should also include the matings recommended within the population of all available Silesian horses of both types. The authors consider introducing such a program essential. It should be also clearly stated in the plan how large proportion of the Silesian mares population could be each year mated to Thoroughbredstallions. Division into two types implies that some fraction of new-type Silesian horses and their progeny would not be regarded as potential parents of individuals for the conservation programme.
