short communication: milk fat composition of 4 cattle breeds in the netherlands.	milk fatty acid (fa) composition was compared among 4 cattle breeds in the netherlands: dutch friesian (df; 47 animals/3 farms), meuse-rhine-yssel (mry; 52/3), groningen white headed (gwh; 45/3), and jersey (jer; 46/3). each cow was sampled once between december 2008 and march 2009 during the indoor housing season, and samples were analyzed using gas chromatography. significant breed differences were found for all traits including fat and protein contents, 13 major individual fa, 9 groups of fa, ...	2011	21257071
differences in milk fat composition predicted by mid-infrared spectrometry among dairy cattle breeds in the netherlands.	the aim of this study was to estimate breed differences in milk fatty acid (fa) profile among 5 dairy cattle breeds present in the netherlands: holstein-friesian (hf), meuse-rhine-yssel (mry), dutch friesian (df), groningen white headed (gwh), and jersey (jer). for this purpose, total fat percentage and detailed fa contents in milk (14 individual fa and 14 groups of fa) predicted from mid-infrared spectra were used. mid-infrared spectrometry profiles were collected during regular milk recording ...	2013	23375975
suitability of cross-bred cows for organic farms based on cross-breeding effects on production and functional traits.	data from 113 dutch organic farms were analysed to determine the effect of cross-breeding on production and functional traits. in total, data on 33 788 lactations between january 2003 and february 2009 from 15 015 cows were available. holstein-friesian pure-bred cows produced most kg of milk in 305 days, but with the lowest percentages of fat and protein of all pure-bred cows in the data set. cross-breeding holstein dairy cows with other breeds (brown swiss, dutch friesian, groningen white heade ...	2013	23171501
