Reproductive and growth performances of four rabbit genotypes

Kermauner, Ajda (avtor), Pohar, Jurij (avtor)

The insemination rate, probability of culling of does after the insemination, weight of does and weight of young, litter size, as well as litter weight were measured in groups of rabbits with different genotype. Four groups were formed: 30 multiparous does of SIKA maternal line (line A) were inseminated with males from the same line (AxA group), 23 multiparous does of SIKA sire line (line C) were inseminated with the males from the same line (CxC group), 30 multiparous does of line A were inseminated with the males from line C(AxC group) and 30 multiparous does of line A were inseminated with the males from Californian breed (AxCal group). The young were individually weighed once a week from birth to weaning (at the age of 35 days). Considering insemination rate, probabiliy of culling and litter size from birth to weaning there were no heterosis effect found. There were no differences between group AxC and AxCal in the majority of studied traits as well, except for the number of stillborn which was in geoup AxC significantly higher than in AxA and AxCal group. Live weight of young in group AxC was significantly higher than of group AxA at each weighting from birth to weaning, and higher than of group CxC at each weighting birth to 21st day of age. Live weight of young in AxC group was significantly higher than live weight of young in AxCal at each weighting.

Izvleček

Primerjali smo uspešnost osemenitve, verjetnost izločitve samice po osemenitvi, telesno maso samic in mladičev ter velikost in maso gnezda v skupinah kuncev različnih genotipov. Formirali smo 4 skupine: 30 samic SIKA materne linije (linija A) smo osemenili s samci iste linije (skupina A x A), 23 samic SIKA očetovske linije (linija C) s samci iste linije (skupina C x C), 30 samic linije A s samci linije C (skupina A x C) in 30 samic linije s samci kalifornijske pasme (skupina A x Cal). Mladiče smo individualno tehtali tedensko od rojstva do odstavitve (na 35. dan starosti). Pri uspešnosti osemenitve, verjetnosti izločitve samic in velikosti gnezda od kotitve do odstavitve se heteozis ni pojavil, prav tako tudi ni bilo razlik med A x C in A x Cal skupino v večini proučevanih lastnosti. Izjema je bilo število mrtvorojenih mladičev v gnezdu, ki je bilo pri A x C skupini višje kot pri Ax A in A x Cal skupini. Kunci v skupini A x C so bili statistično značilno težji od skupine A x A pri vseh detajlih od rojstva do odstavitve, od skupine C x C pa pri tehtanjih od rojstva do 21. dne strosti. Mladiči v skupini A x C so bili težji tudi od skupine A x Cal pri vseh tehtanjih.
