Project description:The objective was to study the transcriptomic changes in adipose tissue in the early stages of lactation, specifically in Bos Taurus, Holstein dairy cattle as a function of milk production and genetic merit. Chip quality backgrounds averaged below 50 units, and 3’/5’ bias on control genes < 2.0. Correlations among replicates were > 0.85.
Project description:To understand the immune response of cows to the apicomplexan parasite Theileria annulata, we used ex vivo isolate cells derived from two infected calve : Holstein 12886 (Bos taurus), which is known to be susceptible to the disease, and Sahiwal 82H (Bos indicus), which is known to be resistant. The infected bovine macrophages of the two species with Theileria were collected and performed multiome 10X Chromium genomics scRNA-Seq.
Project description:Bovine mastitis is an inflammatory disease of the mammary gland with serious economic implications for dairy industries worldwide. We performed total RNA sequencing using whole blood cells collected from multiparous Holstein Friesian dairy cows with naturally occurring mastitis to investigate the changes in systemic gene expression and their association with inflammatory responses. Some related sequencing data are deposited in E-MTAB-9347 and E-MTAB-9348.
Project description:Analysis of key genes and gene networks determining milk productivity of the dairy HF cows Transcriptomes were compared of in the mammary glands of the healthy lactating Holstein Friesian cows of the high- (average 11097 kg milk/lactation) and low- (average 6956 kg milk/lactation) milk yield.
Project description:The objective was to study the transcriptomic changes in adipose tissue in the early stages of lactation, specifically in Bos Taurus, Holstein dairy cattle as a function of milk production and genetic merit. Chip quality backgrounds averaged below 50 units, and 3'/5' bias on control genes < 2.0. Correlations among replicates were > 0.85. The design was a simple paired sampling, with time (30 d prepartum and 14 d postpartum as the sampling times. There was no dietary manipulation. Animals were all first calving Holstein heifers, all raised on the same farm on the same diet
Project description:This experiment was undertaken to document changes in gene expression in the skin of tick-resistant Brahman (Bos indicus) and tick-susceptible Holstein-Friesian (Bos taurus) cattle prior to, and following, infestation with the cattle tick Rhipicephalus (Boophilus) microplus Keywords: Disease state analysis
