Effect Of Double Interspiking On Fertility, Behavior, And Blood Parameters In Broiler Breeder Males Reared Under Heat Stress Conditions, Karianne Mei-Ying Chung
Effect Of Double Interspiking On Fertility, Behavior, And Blood Parameters In Broiler Breeder Males Reared Under Heat Stress Conditions, Karianne Mei-Ying Chung
Masters Theses
Broiler breeders experience a natural decline in fertility levels as a flock ages. A male management practice such as double interspiking could be applied to counteract this decline. Our objective was to investigate the effects of double interspiking on flock fertility, testosterone concentrations, stress responses, and behavioral responses of broiler breeders in heat stressed environments. Two hundred and eighty-eight broiler breeder pullets and thirty-six broiler breeder roosters (Ross 708) were assigned to three groups at 21 weeks of age (WOA). All three groups were housed in slatted floor pens in which room temperature cycled from 23.8 to 30 C to …
Identifying And Understanding The Spatial Distribution Of Bobcat And Coyote Behavior, Ryan Radford Wilson
Identifying And Understanding The Spatial Distribution Of Bobcat And Coyote Behavior, Ryan Radford Wilson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A common observation in animal space use studies is that animals do not use space uniformly, but rather use some areas of their home ranges and territories with much higher intensity than others. Numerous methods have been developed to estimate these "core areas"; however, all of the current methods available are based on arbitrary rules. Additionally, most studies do not attempt to understand what behavioral processes lead to the observed patterns of non-uniform space use. This study has four main objectives: 1) to develop an objective and more precise method for estimating core areas, 2) to understand the processes leading …
Does The Manipulation Of Tail Position Facilitate Extinction Of Canine Phobic Behavior?, Rebecca A. Zarate
Does The Manipulation Of Tail Position Facilitate Extinction Of Canine Phobic Behavior?, Rebecca A. Zarate
Theses and Dissertations - UTB/UTPA
The phobic behavior of interest is tail tucking which is indicative of submission. In this study the tail was physically manipulated by the use of a custom made harness to hold the tail up in a dominant position to ideally extinguish phobic behavior through reciprocal inhibition. The harness did not hold the tail up the entire duration of the interventions, although it still held the base of the tail up. The intervention did not appear to have an affect on the two of the five subjects. The three more phobic canines did display some behavioral changes, although the changes noticed …
Growth And Age At Reproductive Maturity Of The Carolina Pigmy Rattlesnake, Sistrurus M. Miliarius (Reptilia: Serpentes), Kevin Robert Messenger
Growth And Age At Reproductive Maturity Of The Carolina Pigmy Rattlesnake, Sistrurus M. Miliarius (Reptilia: Serpentes), Kevin Robert Messenger
Theses, Dissertations and Capstones
Growth and age at reproductive maturity are life history attributes that play an important role in the development of proper management strategies. The Carolina Pigmy Rattlesnake, Sistrurus m. miliarius, is one of two dwarf rattlesnake species. The subspecies ranges from eastern NC to nearly the southern tip of SC and into the northeastern portion of GA. In NC, where the species’ status is of Special Concern, fragmentation and land development have destroyed most of its historic range. Its small size also makes it highly susceptible to predation. In some parts of the range, commercial collection is another pressure the species …
The Interictal State In Epilepsy And Behavior, Daniel Tice Barkmeier
The Interictal State In Epilepsy And Behavior, Daniel Tice Barkmeier
Wayne State University Dissertations
Epilepsy is one of the most common neurological diseases, affecting up to 1% of the world population. Epilepsy remains poorly understood and there are currently no medications to cure it. Patients with epilepsy have both seizures as well as another type of abnormal activity between seizures, known as interictal spikes. Interictal spikes have thus far been poorly researched, yet growing evidence supports an important role for them in epilepsy. In this project, we first show the high variability between reviewers in marking interictal spikes on intracranial EEG, and then develop and test an automated detection method to solve this problem. …
