dc.description.abstract | Data of 371 Simmental bulls tested at the A.I. Centre "Velika Plana" were analyzed in order to estimate year and month of birth, test-group, herd of origin and body weight effects on body measurements and body development indices. These two groups of traits were considering as body development traits. All observed traits were measured at the start as well as at the end of test. Birth year was significant source of variation for all body development traits, while significance of month of birth was expressed at different statistical levels. Herd of origin effect was gradually reduced over the test, while test-group effect was significance only for body measurements. For body development indices herd of origin have no effect, while test-group effect was significant at different statistical levels. Body weight was very significant source of variation for all body development traits. . | en |
dc.description.abstract | Za ispitivanje različitih izvora varijabilnosti koji imaju uticaj na telesnu razvijenost simentalskih bikova u performans testu iskorišćeni su zvanični podaci Stočarsko veterinarskog centra iz Velike Plane. Za analizu su upotrebljeni podaci o 371 performans testiranom biku. U analizu su bile uključene dve grupe osobina telesne razvijenosti i to linearne telesne dimenzije merene na početku i na kraju testa i indeksi telesne razvijenosti izračunati na osnovu raspoloživih telesnih dimenzija. U model za analizu izvora varijabilnosti bili su uključeni fiksni uticaji godine i meseca rođenja bika, uticaj grupe bika u testu, uticaj matične farme sa koje bik vodi poreklo, kao i telesna masa u odgovarajućem mesecu uzrasta kao nezavisno promenljiva veličina. Godina telenja ispoljila je značajan uticaj na sve osobine telesne razvijenosti, dok je mesec telenja svoj uticaj tokom testa ispoljavao na različitim nivoima statističke značajnosti. Uticaj farme se postepeno smanjivao od početka ka kraju testa, dok je uticaj grupe u testu bio značajan za linearne dimenzije tela. Za indekse telesne razvijenosti farma nije bila značajan izvor varijabilnosti, dok je značajnost grupe bila ispoljena na različitim nivoima. Telesna masa je bila značajan izvor variranja kod obe grupe osobina telesne razvijenosti. . | sr |
