Current breeding tools aiming to improve feed efficiency use definitions based on total dry matter intake (DMI); for example, residual feed intake or feed saved. This research aimed to define alternative traits using existing data that differentiate

Whole genome scan to detect quantitative trait loci for bovine milk protein composition

Autor: G.C.B. Schopen, M.H.P.W. Visker, P.D. Koks, J.A.M. van Arendonk, H. Bovenhuis

The objective of this study was to perform a whole genome scan to detect quantitative trait loci (QTL) for milk protein composition in 849 Holstein-Friesian cows originating from seven sires. One morning milk sample was analysed for the major milk pr

Reliability of genomic evaluations in Holstein-Friesians using haplotypes based on the BovineHD BeadChip

Autor: G.C.B. Schopen, C. Schrooten

Publikováno v: Journal of dairy science. 96(12)

The objectives of this study were to make subsets of high-density (HD) loci based on localized haplotype clusters, without loss of genomic information, to reduce computing time compared with the use of all HD loci and to investigate the effect on the

Whole-genome association study for milk protein composition in dairy cattle

Autor: Erik Mullaart, G.C.B. Schopen, P.D. Koks, M.H.P.W. Visker, J.A.M. van Arendonk, Henk Bovenhuis

Publikováno v: Journal of Dairy Science, 94(6), 3148-3158
Journal of Dairy Science 94 (2011) 6

Our objective was to perform a genome-wide association study for content in bovine milk of α(S1)-casein (α(S1)-CN), α(S2)-casein (α(S2)-CN), β-casein (β-CN), κ-casein (κ-CN), α-lactalbumin (α-LA), β-lactoglobulin (β-LG), casein index, pro

Genome-wide scan to detect quantitative trait loci for milk urea nitrogen in Dutch Holstein-Friesian cows

Autor: Aniek C. Bouwman, G.C.B. Schopen, J.A.M. van Arendonk, H. Bovenhuis, M.H.P.W. Visker

Studies have reported genetic variation in milk urea nitrogen (MUN) between cows, suggesting genetic differences in nitrogen efficiency between cows. In this paper, the results of a genome-wide scan to identify quantitative trait loci (QTL) that cont

Effects of milk fat composition, DGAT1, and SCD1 on fertility traits in Dutch Holstein cattle

Autor: A.G.J.M. Oude Lansink, R.M. Demeter, G.C.B. Schopen, Miranda P.M. Meuwissen, J.A.M. van Arendonk

Recently, selective breeding was proposed as a means of changing the fatty acid composition of milk to improve its nutritional quality. Before implementing such breeding objectives, effects on other economically important traits should be investigate

The objective of this study was to estimate genetic parameters for major milk proteins. One morning milk sample was collected from 1,940 first-parity Holstein-Friesian cows in February or March 2005. Each sample was analyzed with capillary zone elect
