Effects Of Providing Novel Feedstuffs To Livestock On Production And Skeletal Muscle Growth, Laura A. Motsinger
Effects Of Providing Novel Feedstuffs To Livestock On Production And Skeletal Muscle Growth, Laura A. Motsinger
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As the population increases and available land for food production decreases, it is necessary for livestock producers to continually work towards increasing livestock production efficiency. In livestock operations, feed accounts for the majority of input costs associated with raising livestock. As such, it is necessary to improve growth and production of livestock animals, while also optimizing feed utilization. Different feedstuffs can be included in the diet of livestock animals to maximize growth and production. However, the effects of some of these novel feedstuffs on growth and production of livestock animals has not been elucidated. As such, we investigated the effects …
Estimating Cattle Density Using Wildlife Cameras, Emily Bonebrake
Estimating Cattle Density Using Wildlife Cameras, Emily Bonebrake
Undergraduate Honors Capstone Projects
Quantifying the abundance and distribution of animal populations is critical for effective wildlife research and management. Due to their cost-effectiveness, wildlife cameras have become an increasingly popular tool for estimating population densities. Previously, this technique relied on ‘capture-recapture’ models that utilized re-sightings of individually marked animals, but in recent years methods have been developed to estimate the population densities of unmarked animals. One such method is the random encounter and staying time (REST) technique, which does this by assuming that the cumulative time animals stay within the view of the camera scales linearly with the number of individuals. This allows …

Understanding The Decline In Successful Cattle Pregnancies, Andre Tu Nguyen
Research on Capitol Hill
USU junior Andre, a local Loganer, studies computer science and biology.He has been working in an animal science lab. Over time, we have seen a decline in successful dairy cattle pregnancies. This is a huge cause for concern for Utah, with milk sales at an estimated value of $405 million in 2020. Andre’s work has been in studying a certain protein in pregnant cattle; now that he has determined there is a decrease in this protein over the course of the pregnancy, he hopes to see whether that might impact its viability. Andre got involved in research in a high …

Human–Wildlife Interactions
Domestic livestock grazing is the dominant land use on much of the current range inhabited by greater sage-grouse (Centrocercus urophasianus; sage-grouse) in the western United States. Nonnative feral horses (Equus ferus caballus) also inhabit important sage-grouse seasonal habitats. Overabundant feral horse populations and improper grazing by domestic cattle (Bos taurus) can impact the health of sagebrush (Artemisia spp.) and desert shrub rangeland communities and native wildlife. These impacts to sage-grouse can be exacerbated when they affect late brood-rearing habitat, which provide the forbs and arthropods required to fledge broods. Managers require better information …
