Abstract

Dosadašnja istraživanja koja uključuju morfološka obilježja zubala kod divlje svinje (Sus scrofa L.) vrlo su rijetka i uglavnom se temelje na metodama procijene dobi jedinki oba spola te, kod procijene trofejne vrijednosti očnjaka muške populacije-kljova. Osim velikog ekonomskog značaja u lovnom gospodarenju, morfološka obilježja zubala mogu ukazivati i na evolucijske promjene u populacijama divlje svinje, a koje su danas usko povezane s hibridizacijom s domadom svinjom (Sus scrofa domesticus).
Očnjaci divlje svinje krmače koji se nazivaju „klice“, do sada nisu bile u vedoj mjeri istraživane, a mogu biti indirektan pokazatelj uspješnosti i kvalitete populacije. U ovom radu obrađeno je 55 parova sjekača i brusača (ukupno 110 sjekača i 110 brusača) te je napravljena analiza osnovnih morfometrijskih mjera „klica“ divlje svinje prikupljenih redovnim odstrelom u lovnoj 2018/2019. godini na području tri lovišta u Sisačko-moslavačkoj županiji.
Fenotipska obilježja (boja dlake, papci, broj sisa) kod uzorkovanih grla nisu bila u vedoj mjeri izražena, te osnovom toga nije se u potpunosti mogao utvrditi utjecaj hibridizacije na morfometrijska obilježja klica.
Dobiveni rezultati prikazuju ne srazmjeran odnos starosti i tjelesne mase, te veda kolebanja u masi dvogodišnjaka i trogodišnjaka u odnosu na ostale dobne kategorije.
Mjereni parametri očnjaka pokazali su statistički visoke pozitivne ovisnosti (opseg baze brusača (L) i opseg baze brusača (D) r=0,915 (p<0,01) kako međusobno tako i ovisno o starosti grla), kao i negativne (opseg baze klica (D) i dužina (ulaz klica - > sredina oka) (r= -0,604; p<0,01) ) puno niže i uglavnom nesignitifikantne ovisnosti.

Abstract (english)

Previous research involving morphological characteristics of dentals in wild boar (Sus scrofa L.) is very rare and is mainly based on methods of estimating the age of both sexes, and assessing the trophy values of canines (tusks) in male population. Besides the great economic significance in the hunting economy, morphological characteristics of dentals can also indicate evolutionary changes in wild boar populations, which today is closely related to hybridization with domestic swine (Sus scrofa domesticus).
The fangs of a female wild boar (sow) which are called "klice" have not been explored to a greater extent, but can be an indirect indicator of the success and quality of the population. In this paper 55 pairs of cutters and grinders were processed (total of 110 cutters and 110 whetters) and analysis of basic morphometric measures of "klice" of a female wild bore were done. All of the tusks were collected after the kill in a regular hunting season 2018/2019., in the area of three hunting grounds in Sisačko-Moslavačka županija.
Phenotype characteristics (coat color, hoof, teat number) of the analyzed female wild boar samples did not differ to much; so based on this we could not fully determine the effect of hybridization on the morphometric characteristics of "klice".
The results obtained show a disproportion between age and body mass, and greater fluctuations in the mass of two year olds and three year olds compared to other age categories.
The measured canine parameters show statistical high positive dependencies (the circumference of the grinder base (L) and the circumference of the whetter (D) r = 0,915 (p < 0.01), as well as with each other as with the age of the animal; and also negative (the circumferenceof the base of "klice" (D) and length (the socket of "klice" => the centre of the "eye") (r = -0.604; p < 0.01) much lower and largely non-significant dependencies.
