“Invited review: Academic and applied approach to evaluating longevity in dairy cows.” Journal of Dairy Science Vol. 103 No. 12, 2020.

This article reviews the “Hot topic: Detecting digital dermatitis with computer vision,”  research from the Journal of Dairy Science (Vol. 103 No. 10, 2020) to help answer the question of whether it is better to have two dry cow diets – far-off and close-up, or is one dry cow diet throughout the dry period enough? The authors designed three diets: a low-energy (LO), high-fibre diet fed throughout the dry period; a high-energy (HI) diet fed throughout the dry period; and a combination of these (LO+HI), namely a low-energy diet fed during the far-off period and a high-energy diet fed during the close-up period.
