Electronic Theses and Dissertations

This study aimed to evaluate the transcriptomic profile of both corium tissue from lactating dairy cows experiencing sole ulcers and skin lesions from lactating dairy cows diagnosed with digital dermatitis (DD). Hoof biopsies were performed in multiparous Holstein dairy cows selected based on their condition as clinically healthy or diagnosed with sole ulcers (n=7/group). Similarly, skin biopsies were taken from the center of active (M2/M4.1) DD lesions or non-active (M0/M4/M1) from multiparous Holstein dairy cows (n = 7/group) to assess the impact of DD on the skin transcriptome via RNA-seq analysis. All RNA samples were sequenced using Illumina, NovaSeq S4 …
