Something To Celebrate?: Demoting Dairy In Canada's National Food Guide, Maneesha Deckha
Something To Celebrate?: Demoting Dairy In Canada's National Food Guide, Maneesha Deckha
Journal of Food Law & Policy
In early 2019, the Canadian Government released the much-anticipated new Canada Food Guide. It is a food guide that de-emphasizes dairy products and promotes plant-based eating. Notably, in the new version, milk and milk products are de-listed as one of the previously four essential food groups. On the surface, it seems that the federal government is promoting veganism and helping to bring about a friendlier future for animals and humans harmed by being producers and consumers of dairy, as the new Guide may seriously contract the currently robust Canadian dairy industry and its powerful lobby. On closer inspection, the messaging …

Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan A. Lichtenwalter, Jason K. Apple, Beth Kegley, Tsung C. Tsai
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Overall, no effect of teat order was found on average daily gain, average daily feed intake, gain-to-feed ratio, or body weight among pigs from each section …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

Use Of Anti-Mullerian Hormone To Select For Fertility In Beef Heifers, Hannah Newberry, Beth Kegley, Charles Rosenkrans, Rick Rorie
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A study was conducted to determine whether concentration of serum Anti-Mullerian Hormone (AMH) at weaning and/or breeding could predict subsequent fertility in beef heifers. Frequency distribution was used to assign serum AMH concentration measured at weaning, breeding, and the change from weaning to breeding into quartiles. Comparison of heifers based on serum AMH quartiles at weaning failed (P ≥ 0.35) to detect any effect of AMH on subsequent heifer cyclicity at breeding, estrous response after synchronization, artificial insemination (AI) pregnancy rate, overall breeding season pregnancy rate, or estimated estrous cycle of the breeding season when conception occurred. Based on AMH …

Palatability Of Teff Grass By Horses, Rachel R. Cummins, Kenneth Coffey, Nancy Jack, Kathleen Jogan, Edward Gbur, Robert Rhein, Dirk Philipp, Melissa Adams, William Smith, Katherine Clayton
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Most forages commonly used to feed horses have potential detriments including blister beetles or excessive fiber concentrations. Teff grass (T), a warm-season annual forage, has the potential to be a good alternative for horses because of its lack of observed disorders. Our objective was to compare preference by horses for T harvested under different conditions with that of bermudagrass (B) harvested at two maturities. Six different forages were evaluated: T harvested at the late vegetative stage (TLV), at late bloom but that incurred 33 mm of rainfall between mowing and baling (TLBR), with caryopsis visible (TES), or at soft dough …

Bovine cytochrome P450 3A28 is responsible for metabolizing ergot alkaloids that cattle ingest when feeding on endophyte-infested tall fescue grass. The objective of this research was to determine associations among genotype, transportation, and stress responses. Angus crossbred steers (n = 47) were genotyped (CC, CG, or GG) for a single-nucleotide polymorphism (C994G) in cytochrome P450 3A28. Genotypes were determined by polymerase chain reaction (PCR) amplification followed by restriction enzyme (Alu1) digestion. Steers were backgrounded on a mixedcultivar tall fescue pasture. Following the stocker phase, steers were transported to the feedlot for finishing. Stress responses were determined 27 h prior to, …

Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested for safety if accidently overfed to broiler breeders. In order to simulate a feed mixing error at a feed mill, Improved Milbond-TX® was overfed to broiler breeders to see if this would cause any negative effects on bird performance. A typical corn-soybean based diet supplemented with Milbond-TX mycotoxin binder at three different levels of inclusion (0%, 0.5%, and 1%) was fed to …

Journal of the Arkansas Academy of Science
The ditch fencing crayfish, Faxonella clypeata (Hay), is a common and widespread crayfish that inhabits roadside ditches, intermittent first-order streams, shallow sloughs with heavy vegetation, and edges of swamps in Arkansas. Between 1997-2012, we made 55 collections of F. clypeata in 34 counties throughout eastern Arkansas, including 23 counties where F. clypeata had not been previously documented. At most of these locations within the West Gulf Coastal and Mississippi Alluvial Plain provinces, F. clypeata was found to be a locally abundant crayfish. With regard to conservation status, F. clypeata should be considered as “Currently Stable” due to its widespread distribution …

Journal of the Arkansas Academy of Science
We collected and examined 16 Fowler’s toads, Anaxyrus fowleri, and one dwarf American toad, Anaxyrus americanus charlesmithi, in central Arkansas in 2011. Collection was initiated by observation of abnormal toads. Toads were euthanized, measured, photographed, and deposited in the Arkansas State University herpetological collection. Several toads were radiographed. We found various abnormalities in both forelimbs and hindlimbs and on both sides of the body. The causes of the abnormalities remain unknown and will require further studies to determine if the environment is imperiled.

A Novel Gene Silencing Vector For Plant Genomics And Biotechnology, Dustin Hoover, Scott Nicholson, Vibha Srivastava
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Gene silencing is a process of suppressing activity of specific genes by producing “interfering” RNA encoded by foreign genes. This process serves as the principle of genetic modification in plants and animals, which is an important tool in genomics and biotechnology, allowing scientists to manipulate organisms to better meet human demands. New approaches of gene silencing may enable improvements on current practices of genetic modification, and broaden the application and impact of gene silencing in biotechnology. Recently, a novel vector design consisting of the transcription of short gene fragments lacking transcription termination signals was demonstrated to be effective in partial …

Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Inquiry: The University of Arkansas Undergraduate Research Journal
Our multidisciplinary group at the University of Arkansas has been investigating the suitability of the chicken as a medical model for pulmonary arterial hypertension (PAH) in humans. There are several forms of PAH in humans arising from elevated pulmonary arterial pressure and pulmonary vascular resistance. Spontaneous cases of PAH are known as idiopathic PAH (IPAH), where the exact physiological causes are not known. IPAH patients that do not respond to standard treatments have a prognosis of only a few years. Currently, there is no acceptable animal model for IPAH. As part of our effort to pursue the chicken as model …
