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

Effect of ovariohysterectomy on canine postsurgical leukocyte function

The effect of surgery on phagocytic activity of blood leukocytes and mitogen-induced blastogenesis of lymphocytes was studied in fourteen dogs. Simple ovariohysterectomy with anaesthesia induced by ketamine and xylazine or by ketamine, xylazine and halothane caused a short nonsignificant depression of phagocytic activity that persisted for four hours after surgery. Ingestion capacity of leukocytes decreased significantly immediately after surgery. Mitogen-induced blastogenesis of lymphocytes was depressed significantly in the first 48 hours and despite partial recovery this parameter did not reach the value of the control groups until the end of observation (7 days). A more conspicuous decrease of blastogenic response of blood lymphocytes to mitogens was found after the use of ketamine and xylazine in a dose maintaining anaesthesia. Anaesthesia with ketamine and xylazine in the lower dose and maintained with halothane resulted in a later improvement of the blastogenic response of lymphocytes
