Best Management Practices For Internal Parasite Control In Small Ruminants, Susan Schoenian, Enrique Nelson

Professional Agricultural Workers Journal

Abstract

Internal parasites represent a significant obstacle to a profitable and sustainable US goat industry. In some states, internal parasites are a year-round problem, while in others, they are a more seasonal challenge. Traditionally, parasite control methods relied heavily on antiparasitic drugs called anthelmintics or dewormers. Continued use and misuse of these drugs have resulted in increasingly resistant worm populations, necessitating more holistic or integrated methods of parasite control. A combination of practices will usually be necessary to achieve a satisfactory level of control. This paper discusses best management practices for controlling internal parasites in small ruminants, including pasture and …

Reproductive Technologies Used To Make Goats More Efficient, Seyedmehdi Mobini

Professional Agricultural Workers Journal

Abstract

With the introduction of Boer and Kiko breeds for meat goat production in the United States, more emphasis is being placed on the reproductive management to increase the number of offspring born and weaned and the frequency with which they are produced. It is also desirable to produce out of season kids to take advantage of a market premium for milk and meat. Reproductive manipulations, commercial Artificial Insemination (AI) programs using fresh or frozen semen, and Embryo Transfer (ET) have been developed and are in use most commonly in goats for reproductive efficiency.

Comparison Of Unused Water And Year-Old Used Water For Production Of Channel Catfish In The Biofloc Technology System, Bartholomew W. Green, Kevin K. Schrader, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Since excreted feed nitrogen is bio-transformed efficiently in a fully functional mixotrophic biofloc technology production system, re-using this biofloc water over multiple production cycles should be beneficial. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production characteristics and mineral status, common microbial off-flavors, and water quality dynamics for channel catfish (Ictalurus punctatus) reared in one-year-old waters with low or high total suspended solids used previously for two consecutive catfish biofloc studies or in unused (new) water. Total suspended solids were maintained at 300 to 400 mg/L in the unused and low …

Current Situation And Future Prospects Of The Us Goat Industry, Steve Hart, Roger Merkel, Terry Gipson

Professional Agricultural Workers Journal

Abstract

The current demand for goat meat in the US outstrips domestic supply. There is great potential for industry growth in the meat and dairy sectors. Whereas fiber prices have improved, loss of animals and market resources, labor costs for shearing, and lack of animal genetic resources prevent growth in the short term. As producers age, there is opportunity for new producers to enter the marketplace. Significant challenges exist, like access to local markets and abattoirs, dewormer resistant parasites, and feed costs. Establishing goat feedlots can increase meat supply and industry commercialization. Technologies used for cattle will be expanded for …

History Of The U.S. Goat Industry, Terry A. Gipson

Professional Agricultural Workers Journal

Abstract

Goats were first domesticated in the Fertile Crescent and then spread throughout the world. Goats were brought to North America into the southwestern U.S. in the 17^th century by early Spanish explorers and clergy. These goats are the ancestors of the Spanish goat of Texas and the Lamancha breed of California. English and other European settlers also brought their goats as they moved into the eastern U.S in the 18^th century. Angora goats were first imported in the U.S. in the mid-19^th century and the earliest importation of officially recognized dairy goat breeds occurred in the …

Goat Mortality Composting, Roger Merkel

Professional Agricultural Workers Journal

One lawful method to dispose of animal carcasses is composting. Mortality composting is a “green” method that provides the producer with valuable soil amendments. Composting sites should be away from water sources and public areas. Some states require a facility and/or permit for carcass composting so producers should contact their State Veterinarian. Animal composting generates little to no odor and generates temperatures high enough to kill pathogens. Mortality composting is an aerobic process and requires a proper C:N ratio achieved by using a high carbon source to envelop the carcass, moisture content of roughly 50%, and available oxygen. Common composting …

Optimizing Reproductive Performance In The Goat Herd, Dahlia O'Brien, Stephen Wildeus

Professional Agricultural Workers Journal

Abstract

Reproductive efficiency impacts pregnancy rates, kidding/lambing frequency and number of offspring available for market each year. To enhance reproductive performance, consider breed, selection, nutrition and health, and understand basic female and male reproduction. Proper ration formulation and feeding promotes reproductive function and leads to more offspring. Selecting the highest performing females while culling unproductive does increases reproductive rates. Diseases affect the reproduction and survival of kids, so adopting disease prevention strategies including routine vaccinations and deworming protocols that promote good herd health is necessary. Understanding male and female reproduction are critical in managing puberty, minimizing the effects of seasonality …

Emergence Of Common Lambsquarters (Chenopodium Album L.) Is Influenced By The Landscape Position In Which Seeds Developed, Sharon K. Papiernik, Frank Forcella, Gary B. Amundson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In a 2-yr field study, we evaluated the emergence and early growth of Chenopodium album L. (common lambsquarters) seedlings as affected by the landscape position in which the seeds (i) developed, (ii) overwintered, and (iii) were planted. Results indicated that a higher proportion of seeds originating from lower slope positions emerged compared with seeds originating from the backslope or upper slope. The timing of emergence was the same for all seed source locations. There was no influence of overwintering location on weed emergence. Regardless of the seed source, we observed faster emergence and growth of C. album planted in the …

Effects Of Irrigation And Climate On The High Plains Aquifer, Richard K. Perrin, Felipe Silva, Lilyan E. Fulginiti, Karina A. Schoengold

Cornhusker Economics

The High Plains Aquifer (HPA), sometimes known in Nebraska as the Ogallala Aquifer, is an enormous resource underlying 112 million acres across parts of eight states, from South Dakota to Texas.

Our research has previously estimated that irrigation water drawn from the HPA adds at least $2 billion worth of additional crops per year in Nebraska alone, and $3.5 billion across the entire HPA1.

In the years ahead, world population growth will surely increase the pressure for irrigation from the stock of water in the HPA. But pumping that water from the aquifer can increase the depth to groundwater which …

Evaluation Of A Global Spring Wheat Panel For Stripe Rust: Resistance Loci Validation And Novel Resources Identification, Ibrahim Elbasyoni, Walid M. El-Orabey, Sabah Morsy, P. S. Baenziger, Zakaria Al Ajlouni4, Ismail M. Dweikat

Department of Agronomy and Horticulture: Faculty Publications

Stripe rust (incited by Puccinia striiformis f. sp. tritici) is airborne wheat (Triticum aestivum L.) disease with dynamic virulence evolution. Thus, anticipatory and continued screening in hotspot regions is crucial to identify new pathotypes and integrate new resistance resources to prevent potential disease epidemics. A global wheat panel consisting of 882 landraces and 912 improved accessions was evaluated in two locations in Egypt during 2016 and 2017. Five prevalent and aggressive pathotypes of stripe rust were used to inoculate the accessions during the two growing seasons and two locations under field conditions. The objectives were to evaluate the panel for …

Metabolic Dynamics Of Developing Rice Seeds Under High Night-Time Temperature Stress, Balpreet K. Dhatt, Nathan Abshire, Puneet Paul, Kalani Hasanthika, Jaspreet Sandhu, Qi Zhang, Toshihiro Obata, Harkamal Walia

Department of Agronomy and Horticulture: Faculty Publications

High temperature stress during rice reproductive development results in yield losses. Reduced grain yield and grain quality has been associated with high temperature stress, and specifically with high night-time temperatures (HNT). Characterizing the impact of HNT on the phenotypic and metabolic status of developing rice seeds can provide insights into the mechanisms involved in yield and quality decline. Here, we examined the impact of warmer nights on the morphology and metabolome during early seed development in six diverse rice accessions. Seed size was sensitive to HNT in four of the six genotypes, while seed fertility and seed weight were unaffected. …

Appraisal Or Evaluation? The Impact Of Cap Rates On Financing, Jeff Stokes

Cornhusker Economics

Loan underwriting has long been a crucial function of financial institutions. The C’s of credit (character, capacity, capital, conditions and collateral) are taught in many college-level finance and banking courses and the process is even mentioned in popular movies such as “It’s a Wonderful Life.” The process is also recognized as being costly in terms of time and money. Regulations are promulgated and enforced to assure the safety and soundness of lending institutions. Nevertheless, there are situations when the risk to safety and soundness are so small that less extensive underwriting procedures may be appropriate. Benefits to lenders and borrowers …

Rice Response To Nitrogen Fertilization And Comparison Of Unmanned Aerial Systems And Active Crop Canopy Sensors Vegetative Index To Estimate Rice Yield Potential, Anna Coker

LSU Master's Theses

Nitrogen (N) fertilization is a key component in producing profitable, maximized rice grain yields because yield is directly affected by N fertilizer applications. Economical optimum N rate (EONR) is used to estimate where the N fertilization rate impacts rice grain yield but is still economically efficient. Three common response models, linear-plateau, quadratic-plateau, and quadratic models were used to determine the response of rice to N fertilizer to determine the optimum N fertilization rate. The objective of the first part of this study was to evaluate the models by assessing the coefficients of determination (R²), maximum rice grain yields …

Feed Efficiency And Carcass Metrics In Growing Cattle, David N. Kelly, Craig Murphy, Roy D. Sleator, Michelle M. Judge, Stephen B. Conroy, Donagh P. Berry

Department of Biological Sciences Publications

Some definitions of feed efficiency such as residual energy intake (REI) and residual gain (RG) may not truly reflect production efficiency. The energy sinks used in the derivation of the traits include metabolic live-weight; producers finishing cattle for slaughter are, however, paid on the basis of carcass weight, as opposed to live-weight. The objective of the present study was to explore alternative definitions of REI and RG which are more reflective of production efficiency, and quantify their relationship with performance, ultrasound, and carcass traits across multiple breeds and sexes of cattle. Feed intake and live-weight records were available on 5,172 …

Effect Of Foliar Spray Application Of Zinc Oxide Nanoparticles On Quantitative, Nutritional, And Physiological Parameters Of Foxtail Millet (Setaria Italica L.) Under Field Conditions, Marek Kolenčík, Dávid Ernst, Matej Komár, Martin Šebesta, Martin Urík, Edmund Dobročka, Ivan Černý, Ramakanth Illa, Raghavendra Kanike, Qian Yu, Huan Feng, Denisa Orlová, Gabriela Kratošová

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

It has been shown that the foliar application of inorganic nano-materials on cereal plants during their growth cycle enhances the rate of plant productivity by providing a micro-nutrient source. We therefore studied the effects of foliarly applied ZnO nanoparticles (ZnO NPs) on Setaria italica L. foxtail millet’s quantitative, nutritional, and physiological parameters. Scanning electron microscopy showed that the ZnO NPs have an average particle size under 20 nm and dominant spherically shaped morphology. Energy dispersive X-ray spectrometry then confirmed ZnO NP homogeneity, and X-ray diffraction verified their high crystalline and wurtzite-structure symmetry. Although plant height, thousand grain weight, and grain …

Analysis Of The Value Of A Ewe In The Wa Sheep Industry, John Young, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock published reports

The WA flock is at a historically low level, however, sheep profitability is at record highs so rebuilding the state flock is an industry priority. Minimising ewe losses is a necessary component of the flock rebuilding. As a result of the feed shortage and possible grain shortage with high prices likely due to demand for grain from the east coast, local farmers may be tempted to underfeed their ewes during the summer/autumn period. Awareness and good information regarding the cost of mis-managing ewe nutrition will help minimize this temptation.

Impact Of Feeding Distillers Grains Or Isolated Components In Distillers' Grains To Growing And Finishing Cattle, And The Comparison Of Protein Content And In-Situ Digestibility Of Feeds Commonly Used In Feedlot Diets, Brianna B. Conroy

Department of Animal Science: Dissertations, Theses, and Student Research

The use of distillers' grains originating from biofuel production has become widely used in feedlot diets. Distillers' grains has been identified as having an increased feeding value relative to dry-rolled corn, in recent years the composition of distillers' grains has begun to change due to greater refinement in the ethanol production process. Two feedlot trials were conducted to evaluate the contribution of fat, fiber, and protein from distillers' grains in the diets of growing and finishing cattle. Growing steers were fed a grass hay-based ration, including a corn control diet compared to a diet containing modified distillers' grains plus solubles, …

Incubation Recess Behaviors Influence Nest Survival Of Wild Turkeys, Nicholas W. Bakner, Bret A. Collier, Landon R. Schofield

Faculty Publications

In ground nesting upland birds, reproductive activities contribute to elevated predation risk, so females presumably use multiple strategies to ensure nest success. Identification of drivers reducing predation risk has primarily focused on evaluating vegetative conditions at nest sites, but behavioral decisions manifested through movements during incubation may be additional drivers of nest survival. However, our understanding of how movements during incubation impact nest survival is limited for most ground nesting birds. Using GPS data collected from female Eastern Wild Turkeys (n = 206), we evaluated nest survival as it relates to movement behaviors during incubation, including recess frequency, distance traveled …

Avian Ecological Succession In The Amazon: A Long-Term Case Study Following Experimental Deforestation, Cameron L. Rutt, Vitek Jirinec

Faculty Publications

Approximately 20% of the Brazilian Amazon has now been deforested, and the Amazon is currently experiencing the highest rates of deforestation in a decade, leading to large-scale land-use changes. Roads have consistently been implicated as drivers of ongoing Amazon deforestation and may act as corridors to facilitate species invasions. Long-term data, however, are necessary to determine how ecological succession alters avian communities following deforestation and whether established roads lead to a constant influx of new species. We used data across nearly 40 years from a large-scale deforestation experiment in the central Amazon to examine the avian colonization process in a …
