Regression analysis of milk production traits in Simmental cows / Korelaciona analiza povezanosti proizvodnih osobina kroz tri generacije krava simentalske rase
(Institute for Animal Husbandry, Belgrade, 2011)
The relationship between milk production traits over whole lactations was evaluated across three generations of Simmental cows, i.e. between daughters, dams and grand dams, by a phenotypic regression analysis with whole ...
Sources of variability of growth and body development traits of Simmental bulls in performance test / Izvori varijabilnosti osobina porasta i telesne razvijenosti bikova Simentalske rase u performans testu
(Institute for Animal Husbandry, Belgrade, 2015)
To test the variability of traits of Simmental bulls in performance test, data of the Livestock - Veterinary Centres for Reproduction and Artificial Insemination of Velika Plana and Krnjača were used. In the analysis, data ...
Phenotypic correlation of traits of production and reproduction of simmental cows in different regions of Serbia
(Institute for Animal Husbandry, Belgrade-Zemun, 2019)
The main goal of this research was to examine, using modern
methods, the variability of phenotypic correlations of production performances and
reproductive properties of Simmental cows reared on the farms of individual ...
