Abstract
V diplomskem delu smo preučili literaturo o nekaterih bioloških in fizioloških lastnostih reprodukcijskega trakta ter preučili mere plodnosti (doba med kotitvama, velikost gnezda, uspešnost pripustov in osemenitve, dolžina laktacije, izgube do odstavitve itd.) za namen ocenjevanja reprodukcijskih lastnosti pri kuncih slovenske selekcije SIKA za prirejo mesa, in sicer pri materni SIKA A liniji in terminalni SIKA C liniji. Doba med kotitvama (DMK) je zelo pomembna plodnostna in tehnološka mera ter je dober pokazatelj gospodarnega vodenja reje. V literaturi avtorji navajajo različne podatke o DMK, saj je ta odvisna tudi od usmeritve, predvsem pa od intenzivnosti reje. Iz Letne analize … SIKA linije C (2019) je razvidno, da je bila v obdobju med 2003 in 2018 povprečna DMK pri terminalni SIKA liniji C 76 dni. Podobno velja za samice materne SIKA linije A, vendar je bila pri tej liniji plodnost analizirana za krajše obdobje. Na podlagi primerjave podatkov z dostopno literaturo sklepamo o podaljšani DMK za obe liniji. Liniji sta v analiziranem obdobju dosegali rejski cilj za lastnost število živorojenih mladičev na gnezdo (9 živih mladičev pri liniji A in 8 pri liniji C). Za samico kunca je značilen slabo izražen spolni ciklus, zato je pomembno, da rejci uporabljajo učinkovite metode za pravočasno odkrivanje pojatve (npr. barva vulve). Predstavili smo metode naravnega pripusta in se dotaknili osemenjevanja, v intenzivni reji skoraj nepogrešljivega opravila. Med pomembna hlevska opravila spada tudi ugotavljanje brejosti, kjer s palpacijsko metodo najbolj zanesljivo ugotovimo število zarodkov.

Title:Fertility and reproduction traits in rabbits
Abstract:
The thesis compiled a literature overview of some of the biological and physiological characteristics of the reproductive tract and analysed fertility measures (kindling interval, litter size, insemination rate, lactation length, the preweaning mortality, ect.) for the purpose of evaluating the reproductive traits in Slovenian SIKA rabbits for meat production, namely on the SIKA maternal line A and the SIKA terminal (sire) line C. The kindling interval is a very important fertility and technological measure and is a good indicator of successful breeding management. The authors in the analysed literature state varying data regarding the kindling interval, as it is partly dependent on the orientation and especially the intensity of the breeding. The Yearly analysis…of the SIKA line C (2019) indicates that the average kindling interval for the terminal SIKA line C was 76 days in the period 2003–2018. The does of the maternal SIKA line A express similar results, however, the fertility rate for this particular line was analysed for a shorter period. A comparison of the data with the available literature indicates an extended kindling interval for both lines. During the analysed period, both lines reached the target breeding goal in terms of the number of liveborn kits per litter (9 liveborn kits in line A and 8 in line C). The rabbit doe don't have typical well-defined oestrus cycle, so it is important that breeders use various effective methods for a timely detection of heat (e.g. changes in vulva colour). The methods of natural service are presented, as well as insemination, which is practically indispensable practice in intensive breeding system. Determining pregnancy is another crucial task, where the palpation is the most reliable method to ascertain the number of foetuses.
