Abstract

The aim of this study was to determine the productive traits of cows Simmental breed reared in the breeding area or farm "Planinsko good" Nevesinje, Serbian Republic, Bosnia, or more precisely determine the age of heifers (cows) at first, second and third fertilization (pregnancy), productivity milk in the first three lactations. Special emphasis is given to determining the strength and significance of correlation connection, calculating the correlation coefficients of correlation (rp), between the ages (age) heifers (cows) at first insemination productivity of cows in first three lactations (production - whole and standard lactation), and therefore and make specific findings of research conducted. Based on all the above, it can be said that the farm "Planinsko good" Nevesinje in the analyzed period, achieved satisfactory results in terms of productivity. milk production, namely household, according to the selection plan aimed high milk production, which was achieved in the period analyzed.

Cilj ovog rada bio je utvrđivanje produktivnih osobina krava u tipu simentalske rase gajenih na farmi „Planinsko dobro“ Nevesinje, Republika Srpska, BiH, Istraživanje je obuhvatilo utvrđivanje starosti junica (krava) pri prvoj, drugoj i trećoj oplodnji (bremenitosti), kao i produktivnost mlijeka u prve tri laktacije. Poseban naglasak je dat na utvrđivanje jačine i značajnosti korelacione povezanosti, izračunavanjem koeficijenata korelacije (rp) između uzrasta (starosti) junica (krava) pri prvoj oplodnji i produktivnost krava u prve tri laktacije (proizvodna i standardna laktacija). Na osnovu svega izloženog može se reći da je farma „Planinsko dobro“ Nevesinje u analiziranom periodu postigla zadovoljavajuće rezultate u pogledu produktivnosti, tj. proizvodnje mlijeka, tačnije gazdinstvo je prema selekcijskom planu imalo za cilj visoku proizvodnju mlijeka, što je i ostvareno u analiziranom periodu.
