Feeding And Managing Sheep In Dry Times, Ian Mcfarland, Mandy Curnow, Mike Hyder, Brian Ashton, Danny Roberts

Bulletins 4000 -

Feeding sheep is a significant cost to any sheep or mixed farm enterprise in southern Australia. The cost is usually managed by annually sourcing feed on-farm. However, this feed source can become scarce when we experience unusual dry spells within seasons (termed a 'dry season', such as a dry winter or spring), a late break to the season, a drought year, or even worse, successive drought years.

Climate change research suggests that southern Australia will experience higher annual temperatures and a decline in mean growing season rainfall (particularly winter and spring) over the coming decades. This will affect the productivity …

Initial Evaluation Of Novel Preparations Of Bordetella Avium By Determination Of Antibody Response Titers, Joel Gallagher, Stacy Higgins, Luc Berghman, Billy Hargis

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The efficacy of killed vaccines generally is not equal to live vaccines. However, due to safety and ease of production, they remain a vital part of controlling and preventing diseases. In this study, the immune response to four different vaccination preparation techniques for the agent of bordetellosis of turkeys, Bordetella avium (BA), was compared. Preparation/inactivation techniques included (1) formalin inactivation, (2) opsonization of formalin-inactivated BA, (3) buffered acetic-acid BA inactivation, or (4) opsonization of buffered acetic-acid-inactivated BA. Nonadjuvated suspensions containing equal antigen mass were administered subcutaneously (0.2 mL) at day-of-hatch in all cases. For each treatment (N=40/treatment), plasma samples were …
