Genetic relationships and population structure of 8 horse breeds in the Czech and Slovak Republics were investigated using classification methods for breed discrimination. To demonstrate genetic differences among these breeds, we used genetic information - genotype data of microsatellite markers and classification algorithms - to perform a probabilistic prediction of an individual's breed. In total, 932 unrelated animals were genotyped for 17 microsatellite markers recommended by the ISAG for parentage testing (AHT4, AHT5, ASB2, HMS3, HMS6, HMS7, HTG4, HTG10, VHL20, HTG6, HMS2, HTG7, ASB17, ASB23, CA425, HMS1, LEX3). Algorithms of classification methods - J48 (decision trees); Naive Bayes, Bayes Net (probability predictors); IB1, IB5 (instance-based machine learning methods); and JRip (decision rules)-were used for analysis of their classification performance and of results of classification on this genotype dataset. Selected classification methods (Naive Bayes, Bayes Net, IB 1), based on machine learning and principles of artificial intelligence, appear usable for these tasks.

The material consisted of 60 hybrid boars, from line 990 (female) and Pietrain breeds (male), divided into two groups depending on the litter size in which they were born and reared - group: 7-10 piglets (average 8.8) per litter; group: 11-17 piglets (average 12.5) per litter. The mean body weight of 21 day of live piglets born and reared in larger litters was significantly (P < 0.05) lower than among boars reared in smaller litters. This difference gradually diminished and at day 63 of life both groups had the same average body weight. In the period from 63 to 180 day of life, the boars from smaller litters had a slightly lower rate of growth (statistically insignificant). Boars reared in larger litters at 180 day of life were on average 3 kg heavier. There were no significant differences in fat thickness, lean meat and testicular volume between the assessed groups of young boars. From boars reared in smaller litters ejaculates had a significantly higher (P < 0.05) sperm concentration and total sperm volume.

Materiał badawczy stanowiło 60 knurków mieszańców linii 990 (♀) i rasy pietrain (♂), podzielonych na dwie grupy w zależności od wielkości miotu, w którym się urodziły i odchowywały, grupa: (średnio 8,8 prosiąt w miocie); grupa: (średnio 12,5 prosiąt w miocie). Średnia masa ciała w 21. dniu życia knurków, urodzonych i odchowywanych w miotach większych była istotnie (P ≤ 0,05) mniejsza od knurków odchowywanych w miotach mniejszych. Ta różnica zmniejszała się w trakcie ich wzrostu i w 63. dniu życia knurki osiągnęły taką samą średnią masę ciała w obu grupach. W okresie od 63. do 180. dnia życia knurki pochodzące z mniej licznych miotów charakteryzowały się nieco niższym ale statystycznie nieistotnym tempem wzrostu. Knurki odchowywane w miotach większych w 180. dniu życia ważyły średnio 3 kg więcej. Nie wykazano istotnych różnic w zakresie grubości słoniny, mię- sności oraz wielkości jąder pomiędzy ocenianymi grupami knurków. Od knurów odchowywanych w miotach mniejszych uzyskiwano jednak ejakulaty o istotnie wyższej (P ≤ 0,05) koncentracji nasienia i ogólnej liczbie plemników.

The aim of the study was comparison of the milk performance of primiparous cows from 6 European countries with Polish Holstein-Friesians, as well as to demonstrate the differences within the different genetic groups. Material consisted of data contained in the dairy reports gathered from 26 farm “Healthy Cow” project. The analysis involved data including milk yield and its chemical composition, i.e.: fat, protein, lactose, solids, and urea somatic cells count in milk. On the basis of these results, it was found that the country of origin had significant impact on daily milk yield, % fat, % protein, % of lactose and also affected dry matter content, urea and somatic cells in the milk of lactating cows. Research reviled that there were not differences in milk performance between imported and native cows. However, the breed of cows had an strong impact on daily milk production, % protein, % lactose,% dry weight, as well as urea content and somatic cells count.

Wpływ rasy i pochodzenia pierwiastek na wyniki ich użytkowości mlecznej. Celem badań było porównanie parametrów użytkowości mlecznej i składu mleka pierwiastek pochodzących z 6 krajów europejskich z rówieśnicami utrzymywanymi w Polsce oraz wykazanie różnic między rasami. Materiał do badań stanowiły dane zawarte w raportach wynikowych z 26 gospodarstw. Analizowano takie dane jak: wydajność mleka oraz zawartości: tłuszczu, białka, laktozy, suchej masy, komórek somatycznych i mocznika w mleku. Na podstawie uzyskanych wyników stwierdzono, że kraj pochodzenia pierwiastek okazał się istotnym czynnikiem wpływającym na dobową wydajność mleka, % tłuszczu, % białka, % laktozy. Wpływ ten wykazano również na zawartość suchej masy, mocznika i komórek somatycznych w mleku. Analizując wyniki użytkowości mlecznej pierwiastek importowanych z krajowymi nie wykazano statystycznie istotnych różnic między obiema grupami. Rasa krów miała wpływ na dobową produkcję mleka, % zawartość białka, laktozy i suchej masy, a także na zawartość mocznika oraz komórek somatycznych w uzyskiwanym surowcu.

The postpartal period in high-yielding dairy cows can be characterized as a time when animal has to undergo several important changes affecting all the organism. After pregnancy and parturition, organism has to adapt itself to the lactation and this stressing experience contributes to the high incidence of health disorders. These include ketosis, fatty liver, milk fever, retained placenta, metritis, mastitis, laminitis, and other metabolic and reproductive disorders. They may become clinically manifested in later stages of the reproduction cycle but have their primary cause in early postpartal period. To overcome these problems, every farmer has to practice good herd health management, especially when considering the transition period. To discover the weak points of the herd management we can use some indices that can be determined from the blood samples of dairy cows after partuition. We collected blood samples from 170 dairy cows of Slovak spotted breed 1 to 8 weeks after parturition. None of them manifested clinical signs of any illness. We divided them into the 6 groups depending on the number of weeks post partum.We observed and evaluated the main blood-chemistry parameters of energy and liver metabolism (glukose, triglycerides, total lipids, total cholesterol, non-esterified fatty acids, beta-hydroxybutyrate, total bilirubin), protein metabolism (total immunoglobulins, total protein, albumine, Creatinin, urea) and levels of some serum enzymes (AST, GGT, ALP, CPK, LDH). Even though there were no alterations in the health status present in that time, we found out that some indices, mostly of energy and liver metabolism, such as serum levels of non-esterified fatty acids, triglycerids, etc. were altered. This fact can help us to trace the potentially threatened individuals and to iniciate the steps that would minimize further damage.

The study was conducted to find out the most reliable parameter of the hoof size in relation to the horse body size, exemplified in mares. The mares of four breeds belonging to different origin types were examined: Purebred Arabian, halfbred Anglo-Arabian, primitive Polish Konik and Polish Cold-Blood, 77 mares in total. The mares were four to 13 years old, classified into three age groups. Three body measurements were taken: height at withers, chest circumference and canzon circumference. The boniness index (cannon circumference to height at withers ratio) was also defined. After trimming, three left fore hoof measurements were taken: toe length, solar length and hoof width. Total length and width were calculated as a hoof solar size measure. On the basis of the parameters obtained, nine fore hoof to body dimension ratios were defined. To evaluate the results, least squares means analysis was used and correlation coefficients between body parameters (1), between hoof parameters (2), as well as between body and hoof parameters (3) were identified. The results show the hoof to body dimension ratios grow according to the increasing canzon circumference to height at withers ratio. The hoof width to chest circumference ratio was found to be a useful parameter of the hoof size. The means (%) obtained (5.93±0.10, 6.41±0.08, 6.56±0.11 and 7.26±0.09 in Purebred Arabian, Anglo-Arabian, Polish Konik and Polish Cold-Blood horses,respectively) are suggested as standards to which individual ratios in mares of similar breeds May be compared judging the horse’s conformation. The age hardly affected the hoof solar size to height at withers ratio in mares four to nine years old.

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.

The principal objective of this study was to evaluate the processing value of pork obtained from different breeds reared in Poland. The research material consisted of a part of the m. longissimus thoracis obtained from pigs of different breeds: Duroc, Pietrain, Polish Large White, Polish Landrace and Line 990. It was found that the breed is responsible for significant differences in the quality features of pork. Among the samples analysed, meat from Duroc porkers proved to be of the highest, while that from Pietrain porkers of the lowest quality. Pork from the Duroc breed had the highest content of intramuscular fat, which affected the shear and compression force, two traits having a significant effect on sensory quality. Pork from Pietrain porkers was estimated to have a low processing as well as culinary quality. The significantly lower pH, observed in pork from this breed, resulted in a higher colour lightness and lower water holding capacity. Additionally, such pork demonstrated a hard texture (high shear and compression force). On the basis of the study results one may state that programmes aiming at the improvement of pork quality in Poland should include a wider use of the Duroc and limit the use of the Pietrain breed.

Celem pracy była ocena przydatności przetwórczej mięsa różnych ras świń hodowanych w Polsce. Materiał badawczy stanowił wycinek mięśnia najdłuższego (m. longissimus thoracis) pozyskiwany od świń ras duroc, pietrain, polskiej białej zwisłouchej, wielkiej białej polskiej i linii 990. Stwierdzono, iż rasa świń jest czynnikiem istotnie różnicującym wiele wyróżników jakości pozyskiwanego mięsa. Wśród analizowanej populacji korzystniejszymi cechami jakości charakteryzowało się mięso tuczników rasy duroc, natomiast gorszymi rasy pietrain. Zaobserwowano, iż mięso świń rasy duroc cechowało się dużą zawartością tłuszczu śródmięśniowego, co miało wpływ na małą siłę jego cięcia i ściskania, a tym samym dobrą przydatność kulinarną. Natomiast mięso świń rasy pietrain cechowało się niską jakością zarówno technologiczną, jak i kulinarną. Istotnie niższe pH,, obserwowane w mięsie świń tej rasy, skutkowało dużą jego jasnością (L*) i obniżoną wodochłonnością. Ponadto surowiec ten odznaczał się wysoką siłą cięcia i ściskania. Uzyskane wyniki wskazują, iż poprawę jakości krajowej wieprzowiny można uzyskać przez większe wykorzystanie świń rasy duroc, a ograniczenie wykorzystywania świń rasy pietrain.

The aim of the study was to present carpal flexural deformity cases in dogs, which are seldom reported in literature, from the clinical and biochemical point of view. Carpal flexural deformity was determined in a total of 31 puppies, of which 28 were brought to our clinic and 3 reported by a practicing veterinary surgeon. The puppy's ages ranged between 6-24 weeks, and they belonged to 10 different breeds. Following clinical and radiological examination of the puppies, blood samples were taken and calcium, phosphorus and magnesium values were recorded. Slight increases in these mineral values were determined in some of the patients. A splint with a caudal aluminum support, padded with a large amount of cotton, was applied to all puppies with deformity. This splint was kept on for 10 days and repeated in some cases. The study indicated that lesions can be prevented by applying a light splint in the early stages of deformity and that when dietary planning with balanced commercial foods is enforced deformity does not recur in later stages.

Using the GLM procedure an association was analysed between PIT1 and GHRH SNPS and economically important traits in pigs of three breeds reared in Poland. Significant effect of GHRH/AluI SNP was observed on several quality traits such as water-holding capacity and meat colour (A,B and L*) in Polish Large White pigs (P<0.05), with the differences between alternative homozygotes being 8.1%, and 5% (meat colour), and 16% and 3% (WHC), respectively. With respect to the PIT1 gene polymorphism, it was found that pigs carrying AA genotype presented lower values of growth traits such as feed:gain ratio, daily feed intake and number of days on test compared to BB animals (P<0.05) as well as lower pH24 in loin and ham. In turn, heterozygous pigs (AB) had the highest level of fat and the lowest values of meat traits when compared to both homozygotes. It was concluded that polymorphisms in GHRH and PIT1 genes were not directly associated with quality and carcass traits, and likely they are linked to genetic markers localized on chromosomes 17 and 13. Therefore,further investigations should aim at thorough testing of GHRH and PIT1 loci.

The study was undertaken to ascertain if the normal thrombocyte count in Polish ogar dog differs from normal values in other dog breeds. The reason for this study was constatation that during routine blood analysis in healthy Polish ogar dogs, thrombocytopenia, not related to the clinical state of the animals, was frequently encountered. The study was carried out on 38 Polish ogar dogs. The control group consisted of 80 dogs of various breeds. All the animals were clinically healthy. A full hematological analysis was performed. The mean platelet value in all dog breeds without the Polish ogar dogs was 344.4 ± 6.85, while the mean number of platelets in the Polish ogar dogs amounted to 167 ± 11.6 G/l. The limited genetic material used to rebuild the Polish ogar breed after its drastic decline during the Second World War could be the reason for various, including hematological, abnormalities that with time became a normal characteristic traits for this breed.

The observation was carried out in a group of 70 female cattle in the course of two years. The animals were kept in suckler herds. They were provided with pasture grass and maize silage indoors during the grazing season and with forage ration (silage and hay) in winter. The aim of the study was to assess the effect of year (2001 and 2002), season (spring and autumn), breed (Aberdeen Angus AA, Beef Simmental BS, Blonde d'Aquitaine BA, Charolais CH, Hereford HE and Limousin LI) and reproduction cycle (pregnant heifers PH, non-pregnant heifers NPH, pregnant cows PC, non-pregnant cows NC and lactating cows with calves LCC) on some blood plasma parameters. Mean values of these parameters were following: Total protein 72.37 gl⁻¹ , glucose (Glu) 3.23 mmol∙l⁻¹, urea (Urea) 4.39 mmol∙l⁻¹, bilirubin (Bilir) 4.63 mmol∙l⁻¹, alkaline phosphatase (ALP) 1.02 µkat∙l⁻¹, asparate aminotransferase (AST) 1.29 µkat∙l⁻¹, gamma glutamyltransferase (GMT) 0.30 µkat∙l⁻¹, sodium (Na) 114.33 mmol∙l⁻¹, calcium (Ca) 2.30 mmol∙l⁻¹ and phosphorus (P) 1.99 mmolT1. Year affected TP, Glu, Bilir, ALP, AST (all p<0.01) and urea (p<0.05). Season affected TP, Glu, urea, Bilir, Ca, P (all p<0.01) . There were significant differences in urea, GMT, Ca and P between breeds. Reproduction cycle affected TP and Glu (p<0.05). It can be concluded that year and season affected the observed blood plasma parameters considerably more than breed or reproduction cycle.

Celem badań była ocena wpływu roku (2001 i 2002), pory roku (wiosna i jesień), rasy (Aberdeen Angus AA, Simmental BS, Blonde d'Aquitaine BA, Charolais CH, Hereford HE i Limousin LI) oraz cyklu reprodukcyjnego (jałówki cielne PH, jałówki remontowe NPH, krowy cielne PC, krowy nie cielne NC oraz krowy odchowujące cielęta LCC) na wybrane parametry osocza krwi. Średnie wartości tych parametrów były następujące: białko całkowite (TP) 72.37 gl⁻¹, glukoza (Glu) 3,23 mmol∙l⁻¹, mocznik (Urea) 4,39 mmol∙l⁻¹, bilirubina (Bilir) 4,63 mmol∙l⁻¹, kwaśna fosfataza (ALP) 1,02 |ikat l⁻¹, aminotransferaza asparginianowa (AST) 1,29 ( µkat∙l⁻¹, gamma glutamylotransferaza (GMT) 0,30 pkatT1, sód (Na) 114,33 mmolT1, wapń (Ca) 2,30 mmol∙l⁻¹, i fosfor (P) 1,99 mmol∙l⁻¹, . Rok miał wpływ na poziom TP, Glu, Bilir, ALP, AST (wszystkie p<0,01) oraz mocznik (p<0,05). Pora roku miała wpływ na TP, Glu, mocznik, Bilir, Ca, P (wszystkie p<0,01). Zaobserwowano istotne różnice w zawartości mocznika, GMT, Ca i P pomiędzy rasami. Cykl reprodukcyjny miał wpływ na TP i Glu (p<0,05). Można stwierdzić, że rok i pora roku miały wpływ na obserwowane parametry osocza krwi w znacznie większym stopniu niż rasa i cykl reprodukcyjny.

A simple cryopreservation method described in 1995 by Tselutin et al. was used for freezing the semen of four fancy fowl breeds: White Crested Black Polish (WCBP), Greenleg Partridge (GP),Italian Partridge (IP) and Black Minorca (BP). The differences in quality (ejaculate volume,osmotic pressure, sperm concentration and morphology) of fresh semen between evaluated breeds were observed, as well as the differences in semen freezability. The freezing-thawing process caused significant (P≤0.01) decrease in percentage of live, normal spermatozoa, with coincident increase in percentage of dead spermatozoa and spermatozoa with acrosome defect. In relation to the fresh semen, the number of live, normal spermatozoa that survived cryopreservation procedure constituted 18.1% in WCBP, 25.1% in GP, 26.2% in IP and 33.6% in BM semen.

Badano przydatność prostej metody mrożenia opracowanej i opisanej w 1995 r. przez Tselutina i współautorów do zamrożenia nasienia kogutów czterech amatorskich ras kur: czubatki polskiej (White Crested Black Polish – WCBP), zielononóżki kuropatwianej (Greenleg Partridge – GP), włoszki kuropatwianej (Italian Partridge – IP) i minorki czarnej (Black Minorca – BM). Stwierdzono różnice w jakości nasienia świeżego (objętość ejakulatów, ciśnienie osmotyczne, koncentracja i morfologia plemników) między kogutami ocenianych ras, a także różnice między rasami w podatności nasienia na mrożenie. Proces ekwilibracji nasienia w obecności 6% DMA oraz jego zamrożenie-rozmrożenie powodowały istotny (P≤0,01) spadek liczby plemników żywych, prawidłowo ukształtowanych, przy równoczesnym wzroście liczby plemników martwych lub z uszkodzonym akrosomem. Bez względu na rasę kogutów, mrożenie nasienia zastosowaną metodą powodowało spadek liczby plemników żywych prawidłowo ukształtowanych, których udział w stosunku do udziału w nasieniu świeżym stanowił w przypadku czubatki polskiej 18,1%, zielononóżki kuropatwianej 25,1%, włoszki kuropatwianej 26,2% oraz 33,6% w przypadku minorki czarnej.
