Collecting large volumes of blood from cattle at regular intervals can be difficult to achieve without repeat venepuncture and restraint; a significant concern for animal welfare. This paper describes a method of blood collection from a distance using a jugular vein indwelling catheter, rub-resistant collar, and remote collection set that can be employed for reduced animal stress, increase collection speed and increase collection reliability. The described technique has a reduced complexity compared to previously described methods, reducing the likelihood of failure. The methodology was employed in a pharmacokinetic trial where 24 cattle were concurrently inducted. Serial blood sampling occurred over 48 hours, during which 504 blood sample collections were successful and no collections failed. Throughout the sampling period, cattle were observed sitting, standing, eating and drinking, with few vocalisations suggesting high levels of welfare. Semi-remote collection increased technician safety and blood collection speed, allowing two technicians to collect serial blood samples concurrently from 24 cattle.

|Other||It is with enormous pleasure that we invite you to Perth, Western Australia for the 33rd conference of the Australian Association of Animal Sciences (formerly Australian Society of Animal Production), which will be held at the Esplanade Hotel in the beautiful city of Fremantle, 1st – 4th February, 2021.|
For the last 60+ years this conference has brought together animal production scientists, consultants, extension specialists, producers and students to share information – from blue sky research to practical outcomes. The cross-species forum has allowed researchers to glean knowledge and ideas from outside of their areas of reference and provided an opportunity to communicate with a broad range of animal production specialists.
