Organic Production Of Livestock And Livestock Products In Nebraska, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

USDA “Certified Organic” is a form of production that has received considerable public attention in the last 10 years, particularly among small, beginning and/or minority farmers. Spiking retail prices for red meat and poultry have seemingly accelerated consumer’s interest in organic locally produced products. Consumers demonstrate their desire for these products by paying premiums when purchasing meat products. Producers receive premiums by either directly marketing live animals to consumers that are custom harvested or marketing animals to meat wholesalers. The primary difference is the way premiums are captured. Producers doing custom harvesting capture the full premium whereas producers …

Coyotes, Rick Tischaefer

Wildlife Damage Management Technical Series

The coyote (Canis latrans; Figure 1) is a medium-sized member of the canid family. Once primarily found in western deserts and grasslands, coyotes have expanded their range across North America and into diverse habitats, including urban areas. This expansion occurred during a time of extensive habitat change and efforts by people to suppress coyote populations to prevent damage. Coyotes can cause a variety of conflicts related to agriculture, natural resources, property, and human health and safety. This document highlights a variety of methods for reducing those conflicts. Coyotes are a highly adaptable species and may become habituated to some management …

Vampire Bats: Preparing For Range Expansion Into The U.S., Michael J. Bodenchuk, David L. Bergman

USDA Wildlife Services: Staff Publications

The common vampire bat apparently is expanding its range northwards in Mexico and seems poised to enter the southern United States. Climate models predict suitable habitat in the U.S. in south Texas and parts of southern Arizona. While vampire bats’ northward range expansion is not unexpected, the fact that this species brings a strain of rabies that impacts livestock and people warrants a strategic response. Annual economic damages from bats are estimated between $7M and $9M, largely associated with deaths of livestock from rabies. To prepare for the emerging rabies issue, USDA Wildlife Services programs in Texas and Arizona have …

Grazing Behavior, Forage Quality, And Intake Rates Of Livestock Grazing Pastures Occupied By Prairie Dogs, Jameson R. Brennan, Ken Olson, Patricia Johnson, Janna Block, Chris Schauer

SDSU Beef Day 2020 Summary Publication

Prairie dogs can reduce the carrying capacity on rangelands by up to 50% through direct consumption of vegetation and by clipping plants to improve predator detection. Studies have shown that forage quality and digestibility are greater on prairie dog towns than off-town, however research is lacking that quantifies rates of forage and nutrition intake by cattle grazing pastures occupied by prairie dogs. The objectives of this study were to 1) evaluate relationships between on- and off-town plant communities and cattle grazing locations to identify trends in livestock grazing behavior throughout the growing season, 2) evaluate diet nutrient composition and intake …

Black Bear, Jimmy D. Taylor, James P. Phillips

Wildlife Damage Management Technical Series

The American black bear (Ursus americanus, Figure 1) is a challenging species for wildlife agencies to manage due to its size, intelligence, extensive range, food habits, and adaptability, as well as societal views. In North America alone, agencies receive more than 40,000 complaints about black bear annually. Black bears are known as ‘food-driven’ animals, meaning most conflicts result from a bear’s drive to meet its nutritional needs. Not surprisingly, an overwhelming proportion of conflicts are related to their use of anthropogenic (human) food sources, such as garbage, bird food, and crops. Understanding what drives human-bear conflict is the first part …

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand

Animal Sentience

This commentary expands Wiebers & Feigin’s target article by pinpointing how declining wildlife, expanding livestock and globalisation contribute to the increase in epidemics of zoonotic diseases, the COVID-19 crisis and future health crises. Epidemics and the emergence of zoonoses are manifestations of dysfunctional links with animals, both wild and domestic, requiring a new approach to health and the environment.

Factores De Riesgo Asociados A La Seropositividad A Brucella Abortus En Ganaderías Del Departamento De Putumayo, Colombia, Orlando Gaviria Obregón

Maestría en Agrociencias

Los animales domésticos, como los bovinos, son afectados por varias enfermedades reproductivas, entre afectados se encuentra la brucelosis, la cual tiene problemas en la salud pública y la sanidad animal. El objetivo de este trabajo es identificar los factores de riesgo asociados a la seropositividad a Brucella abortus en ganaderías del departamento de Putumayo, Colombia. Se realizó una investigación epidemiológica mediante un estudio retrospectivo de casos y controles y entrevistas a 90 productores distribuidos así: 30 predios con historial de positividad a B. abortus, 30 predios libres de brucelosis y los 30 restantes que nunca han efectuado análisis serológico para …

Influence Of Livestock And Electrified Fences On Livestock Depredation And Habitat Selection By Grizzly Bears In The Mission Valley, Montana, Kari Lynn Eneas

Graduate Student Theses, Dissertations, & Professional Papers

Balancing protection between livestock and carnivores has been a long-standing challenge in conservation. When encounters between carnivores and livestock or humans result in conflict or livestock depredation, the safety of both wildlife and humans are at risk. Reducing livestock depredation by grizzly bears (Ursus arctos horribilis) will be important as populations continue to recover and expand beyond public lands in the Northern Continental Divide Ecosystem. We used GPS locations from 8 female grizzly bears spanning 5 years in the Mission Valley, Montana, to evaluate the effect of livestock on habitat selection of grizzly bears. The Mission Valley is located on …
