ZNAČAJKE REZERVA GENA I PREPOZNAVANJE RIZIČNIH POPULACIJA SLOVAČKIH KONJA

Submitted work is focused to appraisal and breed characteristics of gene reserves of horses in the Slovak Republic. From available data number of animals of the breeds, bred in the Slovak Republic as well as their comparison to neighbouring European countries were found out. Based on the categorisation of risk populations according to number and structure of breeds is possible to measure the level of their endangering. In complicated situation of past few years the Slovak Republic almost lost historically important breeds Furioso and Nonius, which were connected to our history as a part of cultural heritage. According to breeding documentation 8 endangered breeds are bred in the Slovak Republic, for which it non-recurring financial subsidies are available (namely Lipizzaner, Shagya Arabian, Slovak Warm Blooded horse, Furioso, Nonius, Slovak Sport Pony, Hucul and Muráň Plain type of Norik breed). Critically endangered breeds, which number is less than 100 breeding mares and maximum of 5 breeding stallions could be designed as extreme case of population loss risk (Nonius and Lipizzaner breeds). On behalf of rare gene pool protection it is important to use all the possibilities to increase the population number.Ovaj je rad usredotočen na procjenu i pasminske značajke rezerva gena konja u Slovačkoj Republici. Iz dostupnih podataka otkriven je broj životinja pasmina uzgajanih u Slovačkoj Republici kao i njihova usporedba sa susjednim europskim zemljama. Na temelju kategorizacije rizičnih populacija prema broju i strukturi pasmina moguće je izmjeriti razinu njihovog ugrožavanja. U složenoj situaciji zadnjih nekoliko godina Slovačka Republika je skoro izgubila povijesno važne pasmine Furioso i Nonius koje su povezane s našom poviješću kao dio kulturnog nasljeđa. Prema uzgojnoj dokumentaciji 8 ugroženih pasmina se uzgaja u Slovačkoj Republici za koje je dostupna bespovratna financijska pomoć (to su Lipicanac, Arapski Shagya, Slovački toplokrvni konj, Furioso, Nonius, Slovački športski poni, Hucul i Murian, nizinski tip pasmine Norik). Kritično ugrožene pasmine, čiji je broj manji od 100 rasplodnih kobila i najviše pet rasplodnih pastuha može se smatrati na ekstremnom slučaju gubitak rizičnih populacija (Nonius i Lipicanska pasmina). U ime rijetkih zaštita genofonda važno je koristiti sve mogućnosti povećanja broja populacija

ZNAČAJKE PARAMETARA ENERGETSKOG METABOLIZMA U PASMINI SVINJA MANGALICA

In our work selected parameters of energetic metabolism in blood serum of pigs of Mangalica breed in two age categories: piglets (28–30 days old) and mature sows (14–18 months old) were evaluated. Based on the considering of the results of biochemical examinations different values in sucklings in comparison to mature sows were found, namely the total lipids (5,01 and 5,50 g/l), total cholesterol (1,64 and 1,42 mmol/l), HDL-cholesterol (0,92 and 1,00 mmol/l), triglycerids (0,71 and 0,42 mmol/l), and glucose levels (7,63 and 6,33 mmol/l). Our results corresponds with the values mentioned by other authors in mature sows. Provided examinations will help for identification of blood serum metabolites in pigs of different age categories and for specification of reference interval.U našem su radu ocijenjeni odabrani parametri energetskog metabolizma u serumu krvi svinja pasmine Mangalica u dvije dobne kategorije: praščići (28-30 dana starosti) i odrasle krmače (stare 14-18 mjeseci). Na temelju rezultata biokemijskih ispitivanja nađene su različite vrijednosti u sisajućim praščićima u usporedbi s odraslim krmačama, naime ukupni lipidi 5,01 i 5,50 g/l,u ukupnom kolesterolu (1,64 i 1,42 mol/l), HDL-kolesterolu (0,92 i 1,00mmol/l), trigliceridima (0,71 i 0,42 mmol/l) i razinama glukoze (7,63 i 6,33 mmol/l). Naši rezultati odgovaraju vrijednostima drugih autora u odraslih krmača. Ta će ispitivanja pomoći u identificiranju metabolita u krvnom serumu svinja različitih dobnih kategorija i u specifikaciji referentnog intervala

Genetic variation within and relationships among five subpopulations of Slovak Thoroughbred

Genetic variation at six microsatellite loci was analysed for five Thoroughbred subpopulations to determine the magnitude of genetic differentiation and the genetic relationships among the subpopulations. Significant deviations from Hardy-Weinberg equilibrium were shown for a number of locus-population combinations, with all subpopulations. The genetic diversities and relationships of five Thoroughbred subpopulations were evaluated using six microsatellites recommended by the International Society of Animal Genetics (ISAG). The allele frequencies, the effective numbers of alleles, and the observed and expected heterozygosities were calculated. POPGENE v. 1.31 (Yeh et al., 1997) was used to test for deviations from the Hardy-Weinberg (H-W) equilibrium and to assign FIS estimates (Weir, 1990). The utility of microsatellites for evaluating genetic diversity of horses is discussed
