Department of Animal Science: Faculty Publications

Heat stress and cold stress have a negative influence on cattle welfare and productivity. There have been some studies investigating the influence of cold stress on cattle, however the emphasis within this review is the influence of heat stress on cattle. The impact of hot weather on cattle is of increasing importance due to the changing global environment. Heat stress is a worldwide phenomenon that is associated with reduced animal productivity and welfare, particularly during the summer months. Animal responses to their thermal environment are extremely varied, however, it is clear that the thermal environment influences the health, productivity, and …

The number of antral follicles detectable by ultrasonography in heifers is influenced by age of the dam, because daughters of primiparous cows have fewer antral follicles than daughters of mature cows. We, therefore, hypothesized that heifers with primiparous dams would have fewer primordial follicles in their ovaries than heifers born to mature (4+ y) cows. Angus heifers (n=464) were submitted for ultrasonographic evaluation of antral follicle number at 325, 355, and 385 d of age. Ovaries were collected from a random subset of heifers (n=79) and processed for histological evaluation to determine number of primordial follicles. A greater percentage of …

Department of Animal Science: Faculty Publications

The use of coproducts as an alternative feed source is a common practice when formulating dairy rations. A study using 12 multiparous (79 ± 16 d in milk; mean ± standard deviation) lactating Jersey cows was conducted over 5 mo to evaluate the effects of dried distillers grains with solubles (DDGS) or canola meal on milk and gas production. A replicated 4 × 4 Latin square design was used to compare 4 dietary treatments. Treatments comprised a control (CON) containing no coproducts, a treatment diet containing 10% (dry matter basis) lowfat DDGS (LFDG), a treatment diet containing 10% high-fat DDGS …

Perturbations In Lineage Specification Of Granulosa And Theca Cells May Alter Corpus Luteum Formation And Function, Mohamed A. Abedel-Majed, Sarah M. Romereim, John S. Davis, Andrea S. Cupp

Department of Animal Science: Faculty Publications

Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to be fertilized and a corpus luteum is not formed. The corpus luteum formed from the luteinized somatic follicular cells following ovulation, vasculature cells, and immune cells is critical for progesterone production and maintenance of pregnancy. Follicular theca cells differentiate into small luteal cells (SLCs) that produce progesterone in response to luteinizing hormone (LH), and granulosa cells luteinize to become large luteal cells (LLCs) that have a high rate of basal …

Exploring Mechanisms Of Persistent Cognitive Deficits In Mice With Transient Hyperhomocysteinemia, Reeya Khanal

Neuroscience Scholars Theses

Hyperhomocysteinemia (Hhcy) has been found in the elderly and is considered a risk factor for several neurological diseases, especially Alzheimer’s and Vascular Dementia. Previous studies have found an increase in Blood-Brain Barrier (BBB) leakage, glial activation, neuronal damage, and cognitive deficit with elevated levels of plasma homocysteine. Lowering homocysteine could be an easy and inexpensive way to reduce the risk of dementia. But it is still not known for sure if reducing plasma homocysteine levels can recover cognitive function. In our transient Hhcy model, 28 mice were given Hhcy inducing or nutritionally matched control diet for 8 weeks and then …

Color-Ratio Based Strawberry Plant Localization And Nutrition Deficiency Detection, Xiangling Kong

Electronic Theses and Dissertations

In recent years, precision agriculture has become popular anticipating to partially meet the needs of an ever-growing population with limited resources. Plant localization and nutrient deficiency detection are two important tasks in precision agriculture. In this dissertation, these two tasks are studied by using a new color-ratio(C-R) index technique. Firstly, a low cost and light scene invariant approach is proposed to detect green and yellow leaves based on the color-ratio (C-R) indices. A plant localization approach is then developed using the relative pixel relationships of adjacent plants. Secondly, the Sobel operator and morphology techniques are applied to segment the target …

Energy Content Of Seeds Of Texas Doveweed (Croton Texensis) From The Diet Of Mourning Doves (Zenaida Macroura) From Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Collin S. Deen, Dixie Lozano-Lopez, Emily R. Neilson, Taytumn R. Schlegel-Ridgway

Journal of the Arkansas Academy of Science

We analyzed the energy content of seeds of Texas doveweed (Croton texensis) obtained from the crops of mourning doves (Zenaida macroura) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were removed from crops and dried for 48 hours at 60°C to remove moisture and to standardize masses. Seeds were then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Texas doveweed was greater than many seeds previously reported from the diet of mourning doves.

Behavioural And Ecophysiological Responses Of Marine Benthos To Ocean Acidification And Warming, Ee Zin Ong

School of Biological and Marine Sciences Theses

The atmospheric carbon dioxide concentrations (CO2) are projected to rise from 400 ppm to 1000 ppm by the end of 21st century. The increase in atmospheric CO2 has been absorbed by the ocean resulting in a process called ocean acidification. Concurrently, the increase of atmospheric CO2 also intensifies the greenhouse effect, resulting in an increase of ocean surface temperature. The progressive modification of ocean environment is expected to affect marine ecosystems via changes in species behaviour, physiology and survival that will determine population, interaction within the community, with implications for biodiversity-mediated ecosystem functioning. Therefore, studying the combined effects of both …
