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 ...
The effect of interaction of systematic factors on milk performance of Simmental cows in standard lactation / Efekat interakcije sistematskih faktora na mlečnost krava simentalske rase u standardnim laktacijama
(Institute for Animal Husbandry, Belgrade, 2012)
The effect of interaction between the farm and calving season, as well as the farm and group of lactations on milk performance traits (milk yield, yield of milk fat, 4% fat corrected milk and milk fat content) was analyzed ...
The effect of breeding region and year on milk traits of simmental bull dams / Uticaj odgajivačkog područja i godine na osobine mlečnosti bikovskih majki simentalske rase
(Institute for Animal Husbandry, Belgrade, 2010)
Cows which represent top of the genetic value of the population in regard to their traits are chosen for bull dams. Selection is based on origin, production performance (quantity of milk, milk fat and protein content), ...
The effect of paragenetic factors on body development of Simmental bull dams / Uticaj paragenetskih faktora na telesnu razvijenost bikovskih majki Simentalske rase
(Institute for Animal Husbandry, Belgrade, 2009)
Body development and type are very important indices of production ability of cows, their capacity to consume sufficient quantity of food, produce technologically high quality milk, reduce the energy consumption in production ...
The effect of systematic factors on milk yield in Simmental cows over complete lactations / Uticaj sistematskih faktora na mlečnost krava Simentalske rase u celim laktacijama
(Institute for Animal Husbandry, Belgrade, 2009)
The effect of systematic factors on production traits over complete lactations was investigated in 2,805 Simmental cows born in 1982 and onwards. The cows were housed at three farms in different areas: at the Zlatiborski ...
Production potential of first calving Simmental heifers in Serbia / Proizvodni potencijal prvotelki simentalske rase u Srbiji
(Institute for Animal Husbandry, Belgrade, 2011)
Cattle production in Serbia, and especially milk production, contributes significantly to the value of total agricultural production (20%) and livestock production (45%). Achieved annual rate of milk yield increase of ...
Investigation of the effect of certain paragenetic factors on fertility traits of bull dams of Simmental breed / Ispitivanje dejstva pojedinih paragenetskih faktora na osobine plodnosti bikovskih majki simentalske rase
(Institute for Animal Husbandry, Belgrade, 2005)
Investigation included bull dams of Simmental breed selected on farms of agricultural producers on the territory of the Republic of Serbia. Method of Least Squares - LSMLMW (Harvey 1987) was used for analysis of the effect ...
Investigation of the genetic correlation between milk and fertility traits of first calving cows of Simmental breed / Ispitivanje genetske povezanosti osobina mlečnosti i plodnosti prvotelki simentalske rase
(Institute for Animal Husbandry, Belgrade, 2008)
Investigation of the production capacity of cattle for the purpose of increase of milk and milk fat production, as well as number of calves, greatly depends on phenotypic and genetic variability, heritability and correlation ...
Phenotypic correlations of productive and reproductive traits of Simmental cows / Fenotipske korelacije proizvodnih i reproduktivnih osobina krava simentalske rase
(Institute for Animal Husbandry, Belgrade, 2007)
Research included 3.461 first calving Simmental cows in control, with lactations concluded within one year. All first calving cows were reared by private/individual farmers on the territory of the Republic of Serbia. ...
