Evaluation Of The Selected Nuproxa Feed Additives For Protection Against Lameness And Improving The Wellbeing Of Broilers In The Lameness Challenge Model, Abigail Fanous
Biological Sciences Undergraduate Honors Theses
Bacterial Chondronecrosis with Osteomyelitis (BCO) is a form of bacteria that causes lameness in broiler chickens and is a common concern within the poultry industry. This easily transmissible disease can quickly take over entire livestock of chickens leading to an animal welfare issue. Due to this, it is a pressing issue that must be solved in order to protect the wellbeing of broiler chickens and ensure viable livestock. Nuproxa is a company that specializes in chicken feed in which we used to test different amounts of Panbonis, a dietary supplement, in its effectiveness in protecting broiler chickens against BCO lameness. …
Effect Of Larval Rearing Environment On Female Bicyclus Anynana Mate Choice, Adriana Beruvides
Effect Of Larval Rearing Environment On Female Bicyclus Anynana Mate Choice, Adriana Beruvides
Biological Sciences Undergraduate Honors Theses
Around eighty percent of animals go through metamorphosis or drastic phase changes at some point in their life. We know that juvenile interactions can influence adult behavior and mate choice in species that don’t go through metamorphosis, but we know very little about how social interactions during early life stages of animals who go through metamorphosis affect mate choice. To fill this knowledge gap, I used the butterfly Bicyclus anynana to assess whether female butterflies raised in complete isolation from the beginning of their lives exhibit the same mate preference as butterflies raised in normal social conditions. To test this, …

A common concern in commercial industries profiting from broiler chickens is their inability to yield a completely healthy flock. Bacterial Chondronecrosis with Osteomyelitis poses a threat to these companies by impairing the birds' proximal and distal tibial and femoral heads. In 2000, roughly 17.3% of broiler chickens were affected by Bacterial Chondronecrosis with Osteomyelitis which caused a substantial economic loss in the industry (McNammee et al., 2000). BCO cannot be tied to a particular bacterial species; this experiment focuses on evaluating the efficacy of certain commercial feed additives while determining the bacterial species causing BCO in this set of the …
The Influence Of Temperature And Body Size On Food Consumption In Prairie Lizards (Sceloporus Consobrinus), Morgan Pelley
The Influence Of Temperature And Body Size On Food Consumption In Prairie Lizards (Sceloporus Consobrinus), Morgan Pelley
Biological Sciences Undergraduate Honors Theses
Understanding the effect of temperature on physiological and digestive processes, such as voluntary consumption rate, is critical for assessing the impact of climate change. Food consumption is required for lizard survival and reproduction and its rate is dependent on temperature. For ectotherms, as temperatures increase, the amount of food consumed to meet the energy requirements related to survival and reproduction must also increase. Information on the amount of food voluntarily consumed may aid in determining if lizards can meet energy requirements. Such information could also aid in predicting survival of lizard populations, through construction of predictive climate change models. In …
Effect Of Larval Experience On Learning Mate Preference In Bicyclus Anynana, Taryn Tibbs
Effect Of Larval Experience On Learning Mate Preference In Bicyclus Anynana, Taryn Tibbs
Biological Sciences Undergraduate Honors Theses
Phenotypic traits are shaped by the interaction of an organism's genes and the environment they experience. The plasticity of phenotypic traits is particularly responsive to developmental environments which can shape adult traits, such as expressed behaviors like mate choice and the ability to learn preferences. The Lepidoptera species Bicyclus anynana has been shown to learn mate preference based on social interaction following emergence from the chrysalis, however if and how the social complexity of the larval experience affects this ability to learn is less understood. Here I test the effects of isolation during the larval period on a female’s ability …
