Recent development of economic indicators on Czech dairy farms
Agricultural Economics (AGRICECON), 2023 A reassessment of factors related to milk production economics is needed because of continuing genetic improvements within the main dairy breeds and changes in farm management and the economic environment.

Break-even point analysis for milk production - Selected EU countries
Agricultural Economics (AGRICECON), 2022 Unstable conditions in the milk market in the Czech Republic (CR) and in the European Union (EU), mainly due to volatility of milk prices, are increasing pressure on dairy farmers to maximise production at the lowest possible production costs. Break-even

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011 A consistent link of the raw milk quality (RMQ) to the farmer price is essential. The aim was to analyse the properties of milk quality indicators (MQIs) and propose a new synthetic relative MQI (SQSM) from among various individual MQIs. SQSM could serve

The effects of inbreeding on service period and pregnancy length in Holsteins and Czech Fleckviehs after the first calving [PDF]
Archives Animal Breeding, 2007 Abstract. The effects of inbreeding level on service period (SP) and pregnancy length (PL) were monitored in Holstein and Czech Fleckvieh after the first calving. The levels of inbreeding (FX) ranged from 1.25 to 25 %. SP and PL of inbred cows were compared with their outbred equals – half-sisters, sharing the same sire (n = 1824) and their first ...

Effect of C-CSN and B-CSN genotypes on milk production traits in Czech Flekvieh and Holstein breed
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 The effect of the χ-casein (C-CSN) and β –casein (B-CSN) loci on the milk production traits (milk yield, fat, protein and lactose content) was estimated for 807 and 488 Czech Fleckvieh and 402 and 244 Holstein cows, respectively. Genotypes of C-CNS and B-

Effect of DGAT1, BTN1A1, OLR1, and STAT1 genes on milk production and reproduction traits in the Czech Fleckvieh breed [PDF]
Czech Journal of Animal Science, 2014 The impact of polymorphism of the diacylglycerol acyltransferase (DGAT1), butyrophilin (BTN1A1), oxidized low-density lipoprotein receptor (OLR1), and signal transducer and activator of transcription 1 (STAT1) genes on milk production and reproduction traits in 419 Czech Fleckvieh cows was examined using polymerase chain reaction and restriction ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008 The aim of this study was an evaluation of allele and genotype frequencies of Milkprotein kappa casein (CSN3) in bulls offred by breeding companies (n = 287) and of a real proportion of these fathers (genotypes) in a population of Czech Fleckvieh cows (n

Analysis of population and heterosis effects in crossbred cattle of Czech Fleckvieh and Beef Simmental parentage for growth traits [PDF]
Archives Animal Breeding, 2008 Abstract. Genetic effects, e.f. population and heterosis effects have been estimated for: Czech Fleckvieh, Beef Simmental and various types of their crosses produced in beef cow-calf operations. The best genetic-statistical model was chosen for the analyze of these effects.

Impact of Feeding of Legume‑Cereal mixture Silages on Dairy Cow Milk Thermostability and Quality
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2018 Current changes in climate (increasing drought) and the rise in prices of protein concentrate feed are the reasons for the increasing interest in growing and production and increasing silages from legume‑cereal mixtures (LCM) in rations for dairy cows ...

Genetics and Molecular Research, 2012 Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for ...
