Breeding Maize Maternal Haploid Inducers, Henrique Uliana Trentin, Ursula K. Frei, Thomas Lubberstedt

Agronomy Publications

Maize doubled haploid (DH) lines are usually created in vivo, through crosses with maternal haploid inducers. These inducers have the inherent ability of generating seeds with haploid embryos when used to pollinate other genotypes. The resulting haploid plants are treated with a doubling agent and self-pollinated, producing completely homozygous seeds. This rapid method of inbred line production reduces the length of breeding cycles and, consequently, increases genetic gain. Such advantages explain the wide adoption of this technique by large, well-established maize breeding programs. However, a slower rate of adoption was observed in medium to small-scale breeding programs. The high price ...

The Business Of Hemp In North Carolina: Where The Rubber Meets The Road, Obed Quaicoe, Fafanyo Asiseh, Omoanghe S. Isikhuemhen

Journal of Agricultural Hemp Research

Industrial hemp continues to receive a lot of attention in the United States of America with a projected annual revenue growth rate of 18.4 percent by 2022. The momentum industrial hemp has gathered in the past few years has made it the ‘new lucrative crop’ for people to grow. However, many farmers have jumped into hemp farming without first obtaining a realistic economic analysis of hemp farming. In this paper, we seek to review and explore the economic opportunities and challenges of hemp production as a useful guide for reducing risks and maintaining profitability for farmers in North Carolina ...

Applying Agriculture Curriculum As A Vehicle For Science Learning, Nicole Sorensen

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

Agricultural educators in Nebraska are confronting increasing need to integrate science, technology, engineering, and mathematics (STEM) education into agricultural curriculum. Though there are more than 80 agricultural education programs in Nebraska, the state does not provide many state-based curricula options within agricultural education pathways. The purpose of this exploratory survey research is to learn about the viability of an integrated, agriculture and science-based curriculum that is publicly available to agricultural education instructors. The study posed the questions: (1) What is the feasibility of a publicly available, science-integrated agriculture curriculum within Nebraska agricultural education programs? and (2) What are the benefits ...

Translational Genomics For Improving Sow Fertility, Hiruni R. Wijesena

Theses and Dissertations in Animal Science

Sow fertility traits, such as litter size and number of lifetime parities produced (reproductive longevity), are economically important. Selection for these traits is difficult because they are lowly heritable, polygenic, sex-limited, and express late in life. Age at puberty is an early indicator of reproductive longevity. Gilts that achieve puberty at an early age have a greater probability to produce more parities over their lifetime. However, measuring age at puberty is time consuming and tedious. Identifying pleiotropic polymorphisms that affect age at puberty and other fertility traits, including reproductive longevity, could help to improve the accuracy of genomic prediction for ...

Energy And Amino Acid Metabolism In Lactating Jersey Cows Consuming Feed Byproducts, Kyle Mclain

Theses and Dissertations in Animal Science

Animal protein byproducts are high bypass proteins commonly used in the dairy industry. These bypass proteins can escape the rumen to supply additional amino acids needed to support milk and protein yield. Two of the more popular animal protein byproducts used in the dairy industry are blood meal and hydrolyzed feather meal. In the first experiment, two flow meters were compared using headbox-style calorimeters. The objectives of the first study were to test mass flow meter (MFM) and volumetric flow meter (VFM) by measuring O2 consumption and CO2 production and to illustrate the effects of incomplete gas recovery on estimated ...

The Impact Of Oxidative Stress On Postmortem Meat Quality, Nicolas J. Herrera

Theses and Dissertations in Animal Science

Tenderness is the primary factor to influence consumer palatability in fresh meat. The tenderization of muscle is dependent on proteolytic mechanisms, including calcium dependent, non-lysosomal endogenous enzymes such as calpains and proteasomes. These mechanisms have been indicated alongside apoptosis early postmortem as cascades of apoptotic events promote ideal conditions for postmortem tenderization. Recent literature has identified oxidative stress-mediated events to be linked to apoptotic activity. Oxidative stress is defined as the overwhelming production of reactive species compared to homeostatic, endogenous antioxidants present within muscle systems. These conditions exhaust antioxidant function and facilitate reactive species to alter protein, lipid, or nucleic ...

Impact Of Diet And Quality Grade On Meat Quality Characteristics And Their Relationship To Oxidative Stress, Nicolas Bland

Theses and Dissertations in Animal Science

Marbling and tenderness in meat are some of the most impactful factors for the consumer eating experience. The cause of the relationship between marbling and tenderness is still unresolved. This study was conducted to evaluate the effects of feeding different types of processed corn, with or without distiller grains on oxidative stress, and how that relates to tenderness and shelf life of beef steaks of differing quality grades. Steers (n= 240) were finished on dry rolled corn (DRC), DRC + 30% dried distillers grains (DDGS), steam flaked corn (SFC), or SFC + 30% DDGS. Cattle were fed 10 per pen. Only pens ...

Soybean Aphid Biotype 1 Genome: Insights Into The Invasive Biology And Adaptive Evolution Of A Major Agricultural Pest, Rosanna Giordano, Ravi Kiran Donthu, Jonathan H. Badger, Glen L. Hartman, Arian Avalos, Brad S. Coates, Doris Lagos-Kutz, Matthew E. O'Neal, Sijun Liu, Et Al.

Entomology Publications

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) is a serious pest of the soybean plant, Glycine max, a major world-wide agricultural crop. We assembled a de novo genome sequence of Ap. glycines Biotype 1, from a culture established shortly after this species invaded North America. 20.4% of the Ap. glycines proteome is duplicated. These in-paralogs are enriched with Gene Ontology (GO) categories mostly related to apoptosis, a possible adaptation to plant chemistry and other environmental stressors. Approximately one-third of these genes show parallel duplication in other aphids. But Ap. gossypii, its closest related species, has the lowest number ...

Impact Of Cow Size And Validation Of An Electronic Feeder To Optimize Resources In Beef Production Systems, Rob Ziegler

Theses and Dissertations in Animal Science

Optimizing beef production systems is critical in the longevity of an enterprise. In a time of rapid change and innovation, there are increasingly more opportunities to improve efficiency of livestock production by taking advantage of new technologies. Furthermore, production environments vary drastically in all segments of the beef industry, which influence feed resource availability. Therefore, it is critical to realize the cow type that excels in a given production environment according to management objectives. To gain a better understanding of the optimal cow type in the Nebraska Sandhills, a retrospective analysis was conducted to evaluate increasing cow body weight (BW ...

During the time as a GTA and GRA four surveys were developed to analyze different groups of students and their learning environment and two animal experiments were conducted to evaluate maternal diet and its effect on milk composition and piglet health and growth performance

The surveys given to students ...

A Case Study Comparing The Life Skills Development And Knowledge In Youth Participants Of Horseless And Traditional Horse Programs In Utah, Haley M. Johnson

All Graduate Theses and Dissertations

Traditional horse 4-H programs develop life skills and knowledge in youth. Horseless horse programs lack evaluation for the same benefits. This study evaluated and compared four horseless and seven traditional horse participants from Washington County 4-H in Utah for gains in horse knowledge and development of 10 life skills that are commonly found in 4-H curriculum today: leadership, teamwork, self-responsibility, personal safety, problem solving, decision making, critical thinking, goal setting, communication, and concern for others.

The researcher conducted interviews to learn about life skill experiences of the horse program participants and discover what barriers prevented horseless youth from participating in ...

Soil Amendment And Soil Testing As Nutrient Reduction Strategies For The Peel Integrated Water Initiative, Robert Summers, Peta Richards, David Weaver, David Rowe

Resource management technical reports

The Transform Peel program focuses on 42 000 hectares (ha) due east of Mandurah called the Peel Food Zone, 75 kilometres (km) south of Perth in the shires of Murray and Serpentine Jarrahdale and includes an assessment of intensified and enclosed agriculture and a business park. The Peel Integrated Water Initiative was developed through Transform Peel to identify water sources and minimise the effect of these projects on water quality by reducing the nutrient loads discharged into the Peel–Harvey Estuarine System, which has been suffering from poor water quality for this reason.
