Relationship between energy status and fertility in Czech Fleckvieh cows

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
The aim of this study was to confirm that a negative energy balance expressed by declining body condition score (BCS) can lead to the deterioration of fertility results of Czech Fleckvieh cows.

Impact of Seminal Chemical Elements on the Oxidative Balance in Bovine Seminal Plasma and Spermatozoa

open access: yesJournal of Veterinary Medicine, Volume 2013, Issue 1, 2013., 2013
Mutual relationships between selected chemical elements (Na, K, Fe, Cu, Mg, and Zn), basic motility characteristics (motility and progressive motility), and markers of the oxidative balance (superoxide dismutase, catalase, glutathione, albumin, and malondialdehyde) were investigated in bovine seminal plasma and spermatozoa.

Effect of maize kernel endosperm type and maturity stage on ruminal in situ degradability and post-ruminal in vitro dry matter and starch digestibility

open access: yesCzech Journal of Animal Science, 2016
The objective of this study was to evaluate the interaction effect of maize grain texture (dent vs semi-flint) and two different stages of maturity (1/2 vs 3/4 milk line) on ruminal starch degradability and total tract digestibility using in situ and ...

The analysis of relationships between chemical composition, physical, technological and health indicators and freezing point in raw cow milk

open access: yesCzech Journal of Animal Science, 2010
The milk freezing point (MFP) is used for the control of milk food chain quality especially for possible adulteration with water. A crucial issue is the acceptance of the legislative discrimination limit (RLDL) of MFP for standard quality. The aim was to

Analysis of calibration results for casein determination via indirect method of infrared spectroscopy

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
Casein measurement is important for cheesemaking and control of dairy cow nutrition. Reference Kjeldahl method is not suitable for routine purposes. Infra-red spectroscopy MIR and MIR-FT use can be a solutin. However, their casein specifity is relatively

Effect of sires on wide scale of milk indicators in first calving Czech Fleckvieh cows [PDF]

open access: yesArchives Animal Breeding, 2011
Abstract. The possible genetic impact of sire on cattle populations, herd milk yield and milk traits (fat and protein) have been described in the literature along with its impact on some milk indicators (MIs) as somatic cell count, urea and ketones.

Milk protein genes CSN1S1, CSN2, CSN3, LGB and their relation to genetic values of milk production parameters in Czech Fleckvieh

open access: yesCzech Journal of Animal Science, 2006
Genotypes of milk protein genes, alphaS1-casein (CSN1S1), beta-casein (CSN2), kappa-casein (CSN3) and beta-lactoglobulin (LGB), were detected in 440 individuals of Czech Fleckvieh breed using a PCR-RFLP method.

Relationships among milk yield, body weight, and reproduction in Holstein and Czech Fleckvieh cows [PDF]

open access: yesCzech Journal of Animal Science, 2012
The objective of this study was to determine the dynamics and relative body weight (BW) changes after parturition and their relationships to milk yield in Holstein (H) and Czech Fleckvieh (F) cows, and also the relationships between their BW changes in the first 8 weeks of lactation and reproductive performance.

The Nutritional Composition and Multi‐Omics Analysis of Raw Milk From Normande and Holstein Cows

open access: yesFood Frontiers, Volume 6, Issue 6, Page 3042-3058, November 2025.
Normande milk is characterized by high protein and fat content, whereas Holstein milk is distinguished by its high milk yield. However, few studies have reported on their compositional differences. Thus, we used physicochemical and multi‐omics techniques to investigate the compositional differences between Normande and Holstein raw milks. ABSTRACT Milk

The Effect of Low and High Cowshed Temperatures on the Behaviour and Milk Performance of Czech Fleckvieh Cows [PDF]

open access: yesAnnals of Animal Science, 2016
Abstract A group of 98 Czech Fleckvieh cows (one section) was observed over the period of one year with the aim to determine the variation in their milk performance and behaviour at different cowshed temperatures. Behaviour and milk yield were recorded once a week (on the same day) at 10:00.
