Fertility is one of the most important traits in dairy cattle, and has been steadily declining over the last decades. We herein use state-of-the-art genomic tools, including high-throughput SNP genotyping and next-generation sequencing, to identify a 3.3 Kb deletion in the FANCI gene causing the brachyspina syndrome (BS), a rare recessive genetic defect in Holstein dairy cattle. We determine th...
Aim The objective of this study was to examine the carrier status of theileriosis among apparently healthy cross-bred jersey cattle population of Odisha using conventional blood smear examination and polymerase chain reaction (PCR). Materials and Methods A total of 34 apparently healthy cross-bred Jersey lactating cows were considered in this study. Blood samples were subjected to microscopic...
We herein describe the positional identification of a 2-bp deletion in the open reading frame of the MRC2 receptor causing the recessive Crooked Tail Syndrome in cattle. The resulting frame-shift reveals a premature stop codon that causes nonsense-mediated decay of the mutant messenger RNA, and the virtual absence of functional Endo180 protein in affected animals. Cases exhibit skeletal anomali...
In order to investigate the mechanisms of persistent foot-and-mouth disease virus (FMDV) infection in cattle, transcriptome alterations associated with the FMDV carrier state were characterized using a bovine whole-transcriptome microarray. Eighteen cattle (8 vaccinated with a recombinant FMDV A vaccine, 10 non-vaccinated) were challenged with FMDV A24 Cruzeiro, and the gene expression profiles...
A reverse line blot (RLB) assay was developed for the identification of cattle carrying different species of Theileria and Babesia simultaneously. We included Theileria annulata, T. parva, T. mutans, T. taurotragi, and T. velifera in the assay, as well as parasites belonging to the T. sergenti-T. buffeli-T. orientalis group. The Babesia species included were Babesia bovis, B. bigemina, and B. d...
Cattle transportation by commercial truck carrier is common in the United States, and often cattle are placed within 1 of 8 potential compartments within the truck for the journey. The objective of this research was to determine potential associations between animal wellness (as measured by ADG and health outcomes) during a relatively short backgrounding phase (46.6 +/- 8.5 d) and location with...
*Corresponding Author Rajesh. K. Patel [email protected] The present study investigated the occurrence of an autosomal recessive genetic disease, Bovine Citrullinaemia caused by mutation in Argininosuccinate Synthase (ASS) gene, in Indian Holstein cattle. The Polymerase chain reactionRestriction fragment length polymorphism (PCR-RFLP) analysis was performed on a group of 120 Holstein bulls to...
