Occurrence Of The Invasion Associated Marker (Iam) In Campylobacter Jejuni Isolated From Cattle, Yasser M. Sanad, Issmat I. Kassem, Zhe Liu, Jun Lin, Jeffrey T. Lejeune, Gireesh Rajashekara

Animal Science Publications and Other Works

Background

The invasion associated marker (iam) has been detected in the majority of invasive Campylobacter jejuni retrieved from humans. Furthermore, the detection of iam in C. jejuni isolated from two important hosts, humans and chickens, suggested a role for this marker in C. jejuni's colonization of multiple hosts. However, no data exist regarding the occurrence of this marker in C. jejuni isolated from non-poultry food-animals such as cattle, an increasingly important source for human infections. Since little is known about the genetics associated with C. jejuni's capability for colonizing physiologically disparate hosts, we investigated the occurrence …

Supplementing Distillers Grains In Extensive Beef Cattle Systems, Kelsey Rolfe

Department of Animal Science: Dissertations, Theses, and Student Research

A 3-yr study evaluated effects of supplementing modified wet distillers grains with solubles during summer grazing and subsequent feedlot sorting on long yearling steers. During summer grazing, supplemented steers had greater ADG and were more profitable than non-supplemented steers. At feedlot entry, supplemented steers were 48 kg heavier than non-supplemented steers. Feed efficiency and DMI were not different between supplementation treatments during finishing. Supplemented steers were fed 24 fewer days to reach a similar 12^th rib fat thickness, had greater LM area, and lower marbling compared to non-supplemented steers. Overall profitability favored supplementing steers because less expensive summer gains …

Use Of Modified Cages Attached To Growing Calves To Measure The Effect Of Stable Flies On Dry Matter Intake And Digestibility, And Defensive Movements, L. A. Schole, D. B. Taylor, D. R. Brink, K. J. Hanford

Department of Animal Science: Faculty Publications

The effects of stable flies on growing calves were examined using fly cages attached to the animals. Dry matter intake, DM digestibility (DMD), and behavioral responses of calves were monitored. Nine Holstein calves were exposed to 3 levels of stable flies (0, 10, 100 flies/animal) 3 times daily for 30 min. The study consisted of a 4-period crossover design; each period included 5-d adaptation, 7-d exposure, and 5-d postexposure. Calves were weighed at the beginning and end of each period. Feed consumption was continuously recorded. Fecal samples taken during and after exposure were used to determine DMD. Three calves were …
