EFFECTS OF MARKS ON AGGRESSION AND STRESS IN THE DOMESTIC FOWL (GALLUS GALLUS DOMESTICUS)
(2004-05-17)
Animals are marked for identification in a range of experiments from behavior and wildlife management, to reproduction and pharmacological studies. However, little is known of the impact marks have on animals. The ...
Separating the Effects of Group Size, Density, and Enclosure Size on Movement and Use of Space in Domestic Fowl (Gallus gallus domesticus)
(2008-04-24)
This project was designed to separate the confounded effects of group size, density, and enclosure size, and to examine the role of enclosure design and its related parameters in shaping movement patterns and use of space ...
The effect of agonistic encounters on aggressive response in socially isolated Siamese fighting fish, Betta splendens
(2003-12-16)
Male Siamese fighting fish were held for 7 to 10 weeks either in visually-social conditions (interact aggressively with a mirror image for 2 min, three times a week) or as visually-isolated fish (no aggression, saw only ...
Effects of barrier perches and stocking density on the behavior, space use, and leg health of the domestic fowl (Gallus gallus domesticus)
(2009)
The objective of this study was to discern whether providing enrichment in the form of barrier perches across a range of densities might improve leg and foot health and promote behavioral expression and more even use of ...
Proteomic Profiling and Label-Free Quantification of Bovine Milk Proteins during Experimentally Induced Escherichia coli Mastitis
(2009)
Coliform mastitis has been a primary focus of dairy cattle disease research due to staggering affiliated losses, severe systemic complications arising from host inflammatory response to lipopolysaccharide, and the poor ...
FORAGING STRATEGIES, USE OF SPACE AND AGGRESSIVE BEHAVIOR OF DOMESTIC FOWL (Gallus gallus domesticus)
(2004-05-03)
Domestic fowl were tested in three experiments, all investigating the mediating effects of three group sizes of 5, 10, and 20 individuals, on behavioral responses under varying environmental conditions. The first experiment ...
Genetic Variation in Nitrogen and Phosphorus Levels in Broiler Excreta: Opportunity for Improving both Birds and the Environment
(2010)
The increase in poultry meat consumption has resulted in intensified poultry farming operations with consequent concentration of excreta in major production areas. The nutrient content in the soil surrounding the poultry ...
On-Farm Dry Matter Analysis to Improve Feed Delivery Precision on Dairy Farms
(2011)
Uncertainty in dairy ration content impacts feed efficiency, milk production, expenses, and environmental losses. When measuring silage by weight, unknown changes in dry matter (DM) may change the total mixed ration. The ...
Developing a Methodology for the Assessment of Freedom of Movement: The Influence of Spatial Parameters on Movement and Space Use in Mice (Mus musculus)
(2008-11-26)
Despite recent progress in developing housing conditions that more effectively meet the needs of managed species, there remains a lack of detailed information regarding the influence of a space on animal health and well-being. ...
