Managing Risk In Grazing Operations, Christopher D. Teutsch, Kenneth H. Burdine

Kentucky Grazing Conference

Risk is an inherent part of agricultural production systems. Crane and coworkers (2013) identified five primary areas of risk in grazing operations: 1) MARKETING risk, 2) PRODUCTION risk, 3) LEGAL risk, 4) HUMAN risk, and FINANCIAL risk. These types of risk are described in the accompanying publication entitled “Controlling Risk in Grazing-Based Production Systems” by J. Parsons. This article will discuss the risk associated with “production” in grazing systems, focusing specifically on managing drought in grass based production operations.

Keys To Optimizing Profitability In Cow-Calf Production -- Rooster's Beef, 3 Generations Of Farming & Beef, William Slaton, Becky Slaton

Kentucky Grazing Conference

Rooster's Beef ultimately began with our family farm -Rocky Bluff Farm - now owned by William and Becky Slaton. It is the cattle producer for our beef sold. The farm is named after two Natural Rock Formations on our property. We have several acres of pasture and including some wooded acres. With rotational grazing and intense management, we are able to have 65 cows in a spring calving group, 15 cows in a fall calving group, 3 bulls, 13 replacement heifers, unweaned calves and 12 calves on finisher feed. We also rent ground to raise and put up our own …

Turning Grass Into Cash With Small Ruminants, Kenneth Andries

Kentucky Grazing Conference

As agriculture continues to change, it is important to consider sustainability before starting or expanding any enterprise. One critical factor in any animal agriculture enterprise is controlling feeding costs. Most research indicates feeding is the largest expenses in any livestock enterprise. However, nutrition is critical to overall productivity and the income of the enterprise. Because of this, producers need to find ways to improve nutrient availability while minimizing costs to optimize production and profitability for their livestock enterprise.

Considerations For Making A Profit With Stocker Cattle, Jeff Lehmkuhler

Kentucky Grazing Conference

The southeast is home to more than 7.3 million beef cows (USDA 2018). At an estimated 80% weaning rate and 20% heifer retention, the southeast region would be expected to produce more than 4.6 million feeder calves that would go to market in 2018. The cow-calf industry in the region provides an opportunity for the stocker and backgrounding operations to co-exist. Much of the land in the region is best suited for forage and pasture production, which at the current moment, provides a low cost feed for adding pounds to light weight feeder cattle. Yet, the stocker and backgrounding segments …

Measuring Profitability In Grazing Operations, Kenneth H. Burdine

Kentucky Grazing Conference

When producers make investments in extending their grazing season, they do so in order to obtain an economic benefit. These benefits usually include a reduction in the number of days that stored feed (typically hay) is fed, an increase in carry capacity or stocking rate, or an increase in production level (rates of gain, weaning weights, etc). While all of these are potential benefits of improved grazing systems, a reduction in winter feeding days is often the simplest way to start. When the grazing season is extended, winter feeding days are reduced, and this cost savings can be weighed against …

Expression Of Carbohydrates Biosynthetic Genes In Developing Soybean Seeds, Jayden Rosen, Karen A. Hudson

The Summer Undergraduate Research Fellowship (SURF) Symposium

An essential part of livestock diets is soybean meal, which is a major source of protein, but which also consists of antinutritional carbohydrates. Antinutritional carbohydrates such as raffinose and stachyose lead to irritation to the gut for monogastric livestock as well as unhealthy weight gain. A major objective of soybean genetics is to reduce these antinutritional carbohydrates within the seed and increase the levels of good carbohydrates. This will lead to healthier livestock and better meat quality. To select genes potentially responsible for variation in carbohydrate levels in seeds, the expression of genes encoding several biosynthetic enzymes was measured during …

The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa

The International Student Science Fair 2018

Astrocytomas, from cell line 1321N1,are cancerous astrocytes. These are a type of glial cell in the brain which is responsible for maintaining synaptic contact and the signaling capacities among neurons. They also represent a fundamental element in controlling blood flow and defining brain micro structure. Due to the fact that this variant is cancerous, a condition commonly described as an abnormal cell cycle and uncontrolled reproduction of cells, they have the ability to metastasize.

In the metastatic process of cancer cells the initial phase is know as tumor invasion. This stage consists mainly of the cells migrating away from the …

How Do Different Levels Of Ph Affect The Growth Of Heritage And Regular Radish Plants?, Kathleen Bradie

The International Student Science Fair 2018

The purpose of this experiment was to discover how the pH levels in water affect heritage and regular radish mass. I predicted that if the pH levels are near neutral the plants mass will increase. PH solutions of 3, 5, 7, 9, and 11 were added to my regular and heritage plants over the course of several weeks. After using the pH solutions the radishes were pulled and massed to reveal the results. The results showed that the heritage pH 5 and regular pH 7 radishes grew best.

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Impact Of Ultrasonication On Physicochemical Properties And Digestibility Of Sorghum Starch, Zhihong Wang

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Sorghum, a highly nutritious grain, is usually not considered as a main staple in many families because it is not as easy to be digested as other grains such as rice or maize. But recent studies of ultrasonication shed a light on potential utilization of this world’s fifth important cereal other than being raw material source of biofuel or liquor. This experiment was meant to compare the differences between unsonicated and sonicated sorghum starch in terms of their physical chemical properties and digestion ability. Despite their similarities in shapes under microscopes and their thermal properties, but sonicated sorghum starch was …

The Use Of Potato (Solanum Tuberosum) Suspension Cells For Rapid Screening Of Chloroplast Transformation Vectors, Lindsey Shover

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Chloroplast genetic engineering is unique in that it allows for high levels of gene expression while providing a means of natural bio-confinement. Although the chloroplast genome sequence of over 800 plant species is known, the elements that naturally regulate chloroplast gene expression are poorly understood. Recently, our lab has developed a 264 part modular cloning kit that contains known chloroplast regulatory elements. This kit can be used for the construction of novel chloroplast transformation cassettes; however, functional testing of these cassettes is currently hindered by standard chloroplast transformation technologies. Therefore, the aim of this experiment was to develop a rapid …

Constitutive Expression Of Thioglucoside Glucohydrolase 1 (Tgg1) Decreases Intercellular Trafficking In Arabidopsis Thaliana, Alessandro Francesco Sarno

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Plasmodesmata (PD) are pores that traverse plant cell walls, providing a route for intercellular trafficking of essential metabolites, nutrients, and signaling molecules between adjacent plant cells, thereby aiding communication. The increased size exclusion limit 2 (ise2) mutant of Arabidopsis thaliana has an increased abundance of branched PD, as well as a greater flux of intercellular trafficking. A search for proteins that interact with ISE2 identified THIOGLUCOSIDE GLUCOHYDROLASE 2 (a myrosinase). A. thaliana also encodes a second, closely-related myrosinase, TGG1. Myrosinases are enzymes that catalyze the hydrolysis of glucosinolates, a type of secondary metabolite that are amino acid derivatives. The breakdown …

Testing For The Presence Of Botryosphaeria Dothidea In Branches Of Ceanothus Spinosus Undergoing Dieback, Katarina Carter

Seaver College Research And Scholarly Achievement Symposium

Botryosphaeria dothidea is an opportunistic pathogen found in some of the cavitated branches of the chaparral vegetation in the Santa Monica Mountains. In this study, we focused on investigating the presence of Botryosphaeria dothidea in Ceanothus spinosus located on Pepperdine University’s campus. We wanted to test this hypothesis because we had observed a large amount of dieback in the Ceanothus spinosus population and wanted to identify a possible contributor. Because of the large number of cavitated branches in the Ceanothus spinosus we tested, we hypothesized that they contained fungus. To test this, we took twenty samples of twenty different Ceanothus …

Managing Frost Damaged Alfalfa Stands, Christopher D. Teutsch, Jimmy C. Henning, S. Ray Smith, Tom Keene, Matthew Dixon

Kentucky Alfalfa and Stored Forage Conference

Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.

Harvesting Alfalfa For Quality, Garry D. Lacefield

Integrated Management Of Alfalfa Diseases, Kiersten A. Wise

Kentucky Alfalfa and Stored Forage Conference

Alfalfa diseases can reduce forage quality and the longevity of alfalfa stands. Integrated management of diseases can minimize disease impact and improve forage stand and quality. There are several important pathogens that cause disease on alfalfa, and the occurrence of these diseases, as well as the severity of damage, depend on several factors, including the type of pathogen, the environment, and the level of resistance of the host to a particular disease. In addition, disease presence and severity are also influenced by agronomic practices, particularly sowing dates, cutting dates and frequency, and fertility programs.

An Integrated Pest Management Ipm Approach In Alfalfa Production Systems, Lee H. Townsend

Kentucky Alfalfa and Stored Forage Conference

Alfalfa lends itself to an integrated pest management (IPM) approach for alfalfa weevils and potato leafhoppers, the two key insect pests of the crop. Both species live in most alfalfa fields every summer. However, alfalfa can tolerate low levels of their feeding without costly yield or quality loss.
