Sažetak
Sto trideset zečeva je korišćeno za evaluaciju efekata genotipa, dužine gestacije, sezone, pariteta i pola na osobine porasta dve rasa zečeva i njihovih meleza. Zečevi korišćeni u ogledu su rase novozelandski beli zec (NZV) i činčila (CH). Šest priplodnih mužjaka (tri/rasa) i osamnaest priplodnih ženki (devet/rasa) su predstavljali matično stado. Merene su sledeće osobine: telesna masa (BW), dužina od nosa da ramena (NTS), dužina od ramena do repa (STL), obim srca (HG), dužina tela (TL) i dužine uha (LE). Rezultati su pokazali da je BW zečeva pod uticajem (p<0,05) genotipa, dužine gestacije i sezone. CH x (CH x NZV) potomci imali su bolju BW u uzrastu od 35 i 49 dana starosti, dok su potomci NZV x CH imali bolju BW u uzrastu od 21dana. Zečevi rođeni kasno (32-34 dana) imali su bolju BW 21., 35. i 49. dana, dok su zečevi rođeni tokom ranog perioda sušne sezone imali bolju BW 21., 35. i 49. dana. Genotip je uticao (p<0,05) na sve telsne mere 21., 35. i 49. dana. Dužina gestacije je uticala (p<0,05) na sve telesne mere osim NTS 21., i HG 49. dana, respektivno. Sezona rođenja je takođe uticala (p <0.05) na sve telesne mere osim LE 21. dana. Paritet i pol nisu imali uticaj (p>0,05) na BW, NTS, STL, HG, TL i LE. Zaključeno je da su genotip, dužina gestacije i sezona uticali na BW i dimenzije tela dveju rasa zečeva i njihovih meleza, dok paritet i pol nisu imali efekta.
