Graduate Theses and Dissertations
It is well known that arginine vasotocin (AVT) in birds is involved in physiological homeostasis such as cardiovascular, osmotic regulation as well as reproductive functions. Pertinent to these physiological functions, AVT immunoreactive (-ir) neurons in the hypothalamus have been found associated with hemorrhage, dehydration, oviposition and other physiological regulation. Evidence, however, suggests that AVT also plays significant roles in modulating behavior, memory, stress, and food intake. This dissertation research addresses the latter two neuroendocrine functions of AVT in detail within the chicken brain. First, the functional role of AVT-ir neurons in conjunction with corticotropin releasing hormone (CRH)-ir neurons in the …

Rearing birds on wire flooring has proven to be an effective method for consistently triggering significant levels of lameness in broilers, and while the wire flooring model has been proven effective, more mobile wire floor models have been developed to compliment the facility management conditions within commercial genetic selection programs. The mobile wire floor models have been titled "speed bumps", and through previous evaluation have resulted in significantly higher levels of lameness in broilers compared to litter floor shavings. The current experiment contains two studies (studies 1 and 2). Both studies involved comparing leg weakness between broiler strains; while in …
