The objective of this study was to calculate economic weights for ten current breeding objective traits and for four new traits characterising claw health and feed efficiency in Czech Holstein cattle ...
The objectives of this study were to estimate linkage disequilibrium (LD), describe and scan a haplotype block for the presence of genes that may affect milk production traits in Portuguese Holstein ...
This study was conducted to estimate the genetic parameters of β-hydroxybutyrate (BHBA) and acetone concentration in milk by Fourier transform infrared spectroscopy along with test-day milk production...
Effects of age at first calving (AFC) on functional longevity of Czech Holstein cows and their reproduction traits in the first lactation were analyzed using the first lactation data of 605 538 Holste...
The objective of the study was to determine the effect of growth and development intensity in Holstein replacement heifers on economically important animal traits. The intensity of growth was assessed...
Complex selection indexes are proposed for bulls of Holstein cattle in the Czech Republic. Partial breeding values for milk performance, fertility and body conformation are combined in the index. Conf...
In this study we aimed to evaluate the reduction in dimensionality of 20 linear type traits and more final score in 14,943 Holstein cows in Brazil using factor analysis, and indicate their relationshi...
The Chinese Holstein cattle breed, an introduced breed in China, has been crossbred with native cattle breeds. We hypothesised that the Chinese Holstein local population in Beijing share haplotypes wi...
Osteocalcin (OC), a marker of bone turnover, displays patterns in relation to physiological and genetic factors. Here, we present an association study in a population of Chinese Holstein cattle (n = 2...
One of the basic conditions of the economical success in milk production is the high and periodic reproduction of the cows. That means the parturition of a healthy calf from every cow per a year. The ...
Economic weights for milk carrier (water plus lactose), fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of produ...
Multiple-lactation random regression model was applied to test-day records of milk, fat and protein yields in the first three lactations of the Czech Holstein breed. Data included 9 583 cows, 89 584, ...
Survival Kit V3.12 was used to analyse the length of productive life of cattle in theCzechRepublic. The data set consisted of 230 028 registeredHolstein cows. The model included the time-dependent eff...
