The Effect of Air Temperature and Time of Day on Distribution of Czech Fleckvieh Cows Within the Barn

open access: yesActa Universitatis Agriculturae Et Silviculturae Mendelianae Brunensis, 2014
The effect of air temperature and time of day on distribution of Czech Fleckvieh cows within the barn was studied on a dairy farm located in the south of Moravia, CR, (49°12’31.875”N, 16°23’43.146”E). The cows were loose-housed in a barn with stalls. The floor surface was made of separated manure.

Body condition score and milk fatty acid composition in early lactation of Czech Fleckvieh cows

open access: yesActa Universitatis Agriculturae Et Silviculturae Mendelianae Brunensis, 2013
The development of body condition score (BCS) and milk fatty acid composition and its mutual relationships were evaluated in the first 4 weeks of lactation of 50 Czech Fleckvieh cows. Average BCS values ranged from 4.14 at calving to 3.6 points in the 4th week of lactation. The percentage of saturated fatty acids (SFA) tended to slightly increase (69.1

Influence of Legs and Udder Evaluation on Longevity and Selected Milk Production Parameters in Czech Fleckvieh and Montbeliarde Cattle

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
The aim of this study was to evaluate the influence of udder and legs formation on longevity traits (average lactation at culling, lifelong production) and milk production (maximum amount of milk per lactation, fat content in % and kg, protein content in

Polymorphism of CSN3, Pit-1, LGB and its impact on milk performance traits at the Czech Fleckvieh and Holstein breed

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
The effect of known CSN3, Pit-1 and LGB genes single nucleotide polymorphism (SNP) on milk performance traits (milk yield, protein, fat and lactose content, count of somatic cells) at the Czech Fleckvieh and the Holstein cattle breed was estimated.

Joint effects of CSN3 and LGB genotypes and their relation to breeding values of milk production parameters in Czech Fleckvieh [PDF]

open access: yesCzech Journal of Animal Science, 2007
The objective of this study was to estimate the joint effects of CSN3 and LGB genotypes on breeding values of milk production parameters. CSN3 (kappa-casein) and LGB (beta-lactoglobulin) genotypes of 120 Czech Fleckvieh sires were detected using the PCR ...

The Effect of High Summer Temperatures on Reproduction in Holstein and Czech Fleckvieh [PDF]

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2020
The aim of this study was to evaluate the effect of the hot summer season on the length of service period (number of days from calving to the next conception). For the analysis was created two databases of twins. Twins had the same sire and dam and the first and second lactations took place on the same farm. In the first database (105 pairs) one of the

Soil organic carbon stocks and belowground biomass in patches in heterogeneous grassland

open access: yesGrassland Research, Volume 2, Issue 4, Page 279-288, December 2023., 2023
Are patches in low‐input grassland important for the storage of soil organic carbon and belowground biomass? Abstract Background Selective grazing creates stable patches of contrasting sward height, thereby providing different growth conditions for the grass sward above and below ground and potentially affecting soil organic carbon (SOC) stocks.

Influence of summer temperatures on milk content and technological properties of three cow breeds kept under identical conditions [PDF]

open access: yesAgroznanje, 2017
The aim of this study was to assess the influence of summer temperatures on the milk content and technological properties for three different cow breeds. The experiment took place between June and August 2015. We observed 18 dairy cows, kept in identical
