Comparing The Effects Of Monensin And Sodium Butyrate On Coccidia In Post-Weaned Heifers, Hannah R. Coffin
Comparing The Effects Of Monensin And Sodium Butyrate On Coccidia In Post-Weaned Heifers, Hannah R. Coffin
Honors Theses and Capstones
The emergence of antibiotic resistances has raised concerns in society about the widespread use of antibiotics, such as monensin, as growth enhancers in agriculture. Pressure to find alternatives has increased since the European Union banned the use of ionophorous antibiotics. Butyrate supplementation has been found to enhance growth in pre-weaned calves and it has been recently suggested to enhance growth in post-weaned heifers. In a recent study by Rice in 2017, there was a quadratic (P=0.03) response for coccidia counts as sodium butyrate was increased, with the lowest counts being at the intermediate doses. This suggested that butyrate has the …

The Molecular Analysis Of Hawaiian Bird Diets, Alissa C. Scinto
Honors Theses and Capstones
The aim of this project is to utilize high-throughput molecular methods to investigate the diets of three non-native and one native Hawaiian bird species. Next-generation sequencing (NGS) has made it possible to produce thousands of sequencing reads of DNA in a relatively short amount of time. This metabarcoding technology has been used to identify a range of different taxa, from bacteria in the human gut to fungi in the soil. More recently, this approach has been used to identify insects in the diets of birds and other species, including bees and bats. Samples underwent genomic sequencing using a targeted approach …
