Best Management Practices For Internal Parasite Control In Small Ruminants, Susan Schoenian, Enrique Nelson Nov 2019

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 Nov 2019

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 Nov 2019

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 Nov 2019

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 17th 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 18th century. Angora goats were first imported in the U.S. in the mid-19th century and the earliest importation of officially recognized dairy goat breeds occurred in the …


Goat Mortality Composting, Roger Merkel Nov 2019

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 Nov 2019

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 …


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 Nov 2019

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 …


Analysis Of The Value Of A Ewe In The Wa Sheep Industry, John Young, Department Of Primary Industries And Regional Development, Western Australia Nov 2019

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.

Incubation Recess Behaviors Influence Nest Survival Of Wild Turkeys, Nicholas W. Bakner, Bret A. Collier, Landon R. Schofield Nov 2019

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 Nov 2019

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 …


Legacy Effects Of Biodegradable Mulch And Soil Amendments On Vegetable Crops And The Soil, Elise V. H. Reid Nov 2019

Legacy Effects Of Biodegradable Mulch And Soil Amendments On Vegetable Crops And The Soil, Elise V. H. Reid

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Plastic film mulches are used in horticulture to manage weeds, improve water retention, and increase soil temperature. Bioplastics and biofabrics are potentially sustainable alternatives to plastic film; however, they have different rates of in soil degradation. Polylactic acid (PLA) is a 100% biobased polymer that degrades slowly, but could fulfill organic certification to be soil incorporated. Mater-Bi is a commercially available biodegradable plastic (bioplastic), which degrades quickly, but cannot be incorporated in organic systems. Our objectives were to determine the individual and combined effects of soil amendments and residual mulch on vegetable crop yield and soil fertility. In a two-year …

Understanding Nitrogen Limitation In Soybean, Nicolas Cafaro La Menza Nov 2019

Understanding Nitrogen Limitation In Soybean, Nicolas Cafaro La Menza

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Meeting soybean demand on existing cropland area for a global population of 9.7 billion people by the year 2050 requires narrowing the existing gap between average producer yield and yield potential. Soybean relies on two sources on nitrogen (N): biological N2 fixation and indigenous soil N supply. As soybean yield continues to increase, it seems critical to know if there is a yield level at which potential contribution of indigenous nitrogen sources and fixation becomes insufficient to meet crop N requirements for high yields, while still maintaining or increasing protein and oil concentration. This study evaluated N limitation across …

Body Condition Scoring For Horses, Karl Hoopes, Eric Thacker, Linden Greenhalgh Nov 2019

Body Condition Scoring For Horses, Karl Hoopes, Eric Thacker, Linden Greenhalgh

All Current Publications

Horse enthusiasts are often concerned about their horse’s health, appearance and performance. A major key to accomplishing these three goals is to keep your horse at a desirable body condition, or degree of fat cover. However, being able to accurately evaluate a horse to tell if they are over or underweight has been a subjective practice for many years. As with all aspects of horse ownership, horse owners have different opinions on what is an ideal body weight for an individual horse. Also, because horses come in all shapes and sizes, many horse owners are not able to objectively evaluate …
