Organic-PLUS researchers from partners UNIPD, UNIPR and CU have produced 2 recent journal papers on the nutritional analysis and composition of organic milk:
MIR and Vis/NIR spectroscopy cannot authenticate organic bulk milk
This study compares the feasibility of infrared technologies to discriminate organic from conventional bulk milk of Holstein-Friesian cows herds with similar diets and in the same geographic area.
Bulk milk from 24 organic and conventional farms collected across 1 year were analysed with mid-infrared and visible/near-infrared spectroscopy. Our results revealed that both infrared regions performed similarly, and the moderate accuracy obtained could be related to the similarity between the organic and conventional dairy systems selected when using Holstein-Friesians at a generally high level of intensity.
The results of this study have been published in the indexed peer-review Italian Journal of Animal Science. Full appear available at: https://doi.org/10.1080/1828051X.2021.1954559

Detailed comparison between organic and conventional milk from Holstein-Friesian dairy herds in Italy
This study compares the composition of bulk milk of Holstein-Friesian cows from organic and conventional herds with similar diets ingredients and in the same geographic area.
Bulk milk from 24 organic and conventional farms collected across 1 year were analysed for gross composition and mineral, amino acid, and fatty acid profile. Our results revealed that the milk composition was quite similar between organic and conventional dairy systems using Holstein-Friesian at a generally high level of intensity.
The results of this study have been published recently in the indexed peer-review Journal of Dairy Science. Full appear available at: https://doi.org/10.3168/jds.2021-21465
