Productivity And Meat Quality With Meat Goat Management, Trent Drae Dugas

LSU Master's Theses

The growth of kid meat goats and their carcass and meat characteristics with monensin sodium or decoquinate coccidiostats in feed were studied. Seventy-three goats of various breeds were divided into six groups with the treatments of control, monensin and decoquinate. Half of the goats were harvested at day 45 and the rest at day 60. The second harvest monensin group had a larger percentage of the goat carcass as the hind leg (P

Supplementation of permanent pasture with sunn hemp forage or concentrate feed were compared for influences on growth, carcass traits, and meat properties of kid meat goats. Goats …

A Pilot Study Of The Effects Of Mycoplasma Ovipneumoniae Exposure On Domestic Lamb Growth And Performance, Thomas E. Besser, Jessica Levy, Melissa Ackerman, Danielle Nelson, Kezia R. Manlove, Kathleen A. Potter, Jan Busboom, Margaret Benson

Wildland Resources Faculty Publications

Mycoplasma ovipneumoniae is a globally distributed pathogen that has been associated with pneumonia in both domestic and wild Caprinae. It is closely related to M. hyopneumoniae, a respiratory pathogen of swine that is associated with decreased growth rates of pigs as well as clinical respiratory disease. In order to assess the effects of M. ovipneumoniae on lamb performance, we generated a cohort of lambs free of M. ovipneumoniae by segregation of test negative ewes after lambing, then compared the growth and carcass quality traits of M. ovipneumoniae-free and -colonized lambs from weaning to harvest. Some signs of respiratory disease …

Alternative Treatment Options For Controlling Anthelmintic-Resistant Haemonchus Contortus Populations In South Dakota Sheep Herds, Adam Sarah

Electronic Theses and Dissertations

Haemonchus contortus is a common economically important gastrointestinal nematode that obliges the survival and productivity of small ruminants, especially sheep and goats. Anthelmintic resistance is a primary challenge in ruminant health management programs in preventing and controlling the H. contortus populations; therefore, there is a great necessity in finding and developing natural plant products for use as alternatives to commercial anthelmintics for controlling H. contortus in pastured sheep and goats. This dissertation has three major aims conducted in three separate studies: the first in vivo one was to evaluate the extended effect of a springtime, combined-treatment with 3 anthelmintics having …

The Marin County Livestock Protection Program: 15 Years In Review, Stephanie Larson, Devan A. Mcgranahan, Robert M. Timm

Human–Wildlife Interactions

Predation by wild carnivores challenges livestock producers worldwide. To reduce or offset losses due to predation, a variety of predator control methods and compensation schemes have been developed. In 2001, Marin County, California, USA replaced its U.S. Department of Agriculture Wildlife Services (WS) cooperative predator damage management program with a county-run program that emphasized nonlethal methods for preventing and controlling coyote (Canis latrans) predation on domestic sheep (Ovis aries). This new Livestock Protection Program (LPP) cost-shared with livestock producers’ efforts to improve fencing, obtain and maintain guard animals, and other such nonlethal methods, and initially it …

Characterization Of Ovine Monocytes In Response To Haemonchus Contortus Larvae In Vitro And A Novel Role Of Interleukin-13 Inducing Larval Paralysis, Elizabeth Shepherd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Haemonchus contortus is a hematophagous, gastrointestinal parasite affecting small ruminants. Parasitism by H. contortus is the greatest concern of sheep producers in the United States and accounts for billions of dollars in economic loss worldwide. However, different breeds of sheep display differences n natural resistance to H. contortus. St. Croix hair sheep have a remarkable ability to clear H. contortus without the aid of anthelmintics and develop a robust T helper type 2 (Th2) immune response, preventing establishment of infective stage 3 larvae (L3), when compared to susceptible Suffolk sheep. However, the mechanism of development of immune response and …

Smart Sheep Need More Protection, Michael L. Woodruff

Animal Sentience

The target article unequivocally establishes that sheep are far more intelligent and cognitively sophisticated than is generally acknowledged. For this reason, the authors advocate for significantly more stringent regulation of agricultural and research practices when sheep are used. I briefly review the existing US regulations governing the use of sheep in research and discuss the extent to which they are applied to sheep. I then discuss weaknesses in the current regulations, concluding that they should be changed to mandate housing all research animals in environments that accommodate the psychosocial needs of each species.

The Effects Of Sample Storage Conditions On The Microbial Community Composition In Hydraulic Fracturing Produced Water, Daniel Lipus, Amit Vikram, Richard Hammack, Kyle Bibby, Djuna Gulliver

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The petroleum industry has an increasing interest in understanding the microbial communities driving biofouling and biocorrosion in reservoirs, wells, and infrastructure. However, sampling of the relevant produced fluids from subsurface environments for microbiological analyses is often challenged by high liquid pressures, workplace regulations, operator liability concerns, and remote sampling locations. These challenges result in infrequent sampling opportunities and the need to store and preserve the collected samples for several days or weeks. Maintaining a representative microbial community structure from produced fluid samples throughout storage and handling is essential for accurate results of downstream microbial analyses. Currently, no sample handling or …

Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm

Animal Science Undergraduate Honors Theses

Abstract

Goats have a very long history with mankind and are commonly used as a nutritious red meat source around the world. The supply of goat meat in the United States does not meet the growing demand from ethnic consumers. This provides an economic opportunity in Arkansas agriculture because goats are uniquely adapted to the Ozark environment. There is a wide gap in caprine research which facilitated the conception of the study’s objectives to determine whether prepartum milk in goats showed a sudden rise in calcium levels within 24 to 48 hours of kidding and to ascertain whether an increased …

2018 Lambing Survey, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock published reports

The 2018 season brought challenging times for sheep producers in WA and there were wide reports of low lambing rates.

Many areas had a very late start coupled with low winter growth, but saw a wet warm spring bring high pasture growth rates (PGR). Other areas, particularly the South Coast and central south region recorded decile 1 rainfall and grew minimal pasture throughout the season (Appendix 4). All of this was on the back of a poor spring in 2017.

To better understand the impacts of poor and variable seasons on lambing and turnoff rates and to map the impact …

Lambing And Lactation, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The first 48 hours of a lamb’s life are critical – around 90% of lamb mortality from birth to weaning occurs within this period. It is also a critical period of time for the ewe. She is at risk during birth, has her highest demand for food and is vulnerable to sudden changes in diet and conditions.

Does Experience With Sagebrush In Utero And Early In Life Influence Use Of Sagebrush By Sheep?, Juan J. Villalba, Fred Provenza, Ashley Longmore

Poisonous Plant Research (PPR)

Learning from mother begins early in the developmental process and can have lifelong effects when it comes to foraging behavior. Pregnancy is not just an incubation period but a starting point for animal well-being and disease later in life. A better understanding of the effects that early exposure to unpalatable feeds impinges on their use later in life may help create management plans that utilize grazing animals to their full potential as landscape manipulators.

Thus, the objective of this research was to explore how experience in utero and early in life with sagebrush (Artemesia tridentata spp. tridentata) -a …

The Sheep and Goat Industry Funding Scheme (IFS) has been operating since 2010 to address biosecurity threats relevant to the Western Australian (WA) sheep and goat industry. The Scheme was established by regulation under the Biosecurity and Agriculture Management Act 2007 to enable sheep and goat producers to identify pest and disease priorities at a whole-of-industry level and raise funds for activities to address these priorities.

There are currently three Industry Funding Schemes in operation. In addition to the Sheep and Goat IFS, there is a Cattle IFS and a Grains, Seeds and Hay IFS. The three IFSs operate in …

The Impact Of Marking Rates, Turn-Off And Mortality Rates On The Wa Sheep Flock, Kate Pritchett

Animal production and livestock research reports

The Western Australian sheep flock peaked at 38.4 million head in 1990. Following the collapse of the reserve price scheme for wool and subsequent low prices combined with improved returns for crops, the WA flock entered a period of decline. The WA flock had fallen to approximately 14.2 million at the beginning of 2016/17. The dramatically reduced flock has also undergone a change in structure over this time, with the proportion of wethers in the flock being reduced from 32% of the flock to around 7%, and the proportion of breeding ewes increasing to accommodate the increased importance of lamb …

Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas

Senior Honors Projects

Animal welfare is one of the most important parts of animal management. Apart from other measures of good animal welfare, like being in good health, animal behavior can be indicative of the animal’s internal state and is often one of the first signs of improper welfare. Stereotypies, or stereotypic behavior, are commonly viewed as a symptom of improper animal welfare. Unenriched, or barren, environments associated with farmed livestock have long been associated with inducing stereotypic behavior. The addition of precise enrichment to the animals’ environment is a common remedy for stereotypic behavior. With respect to stereotypic goat behavior, few empirical …

An Analysis Of The Characteristics And Practices Of Selected Florida Small Livestock Producers: A Focus On Production And Processing, Jannette R. Bartlett, David Nii O. Tackie, Dana Reid, Akua Adu-Gyamfi, Angela Mckenzie-Jakes

Professional Agricultural Workers Journal

The study assessed the characteristics and practices of small livestock producers, emphasizing production and processing. Data were obtained from a convenience sample of seventy small producers from selected counties in Florida, and analyzed using descriptive statistics, including chi-square tests. The socioeconomic characteristics showed that part-time producers, White producers, middle-aged producers, fairly educated producers, and moderate-income producers dominated the group. A majority of the producers practiced rotational grazing, fed a combination of forage and concentrate, and less than half conducted soil tests regularly. Moreover, over half had parasite problems and treated them primarily with anthelmintics. Nearly all producers sold animals live, …

Managing Pregnancy In Ewes, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The health and nutrition of the pregnant ewe largely determines how successful lambing is in any given year.

Careful monitoring and management of the pregnant ewe during the 5-month foetal development will help her cope with the rigours of birth and lactation, and also influence lamb survival, birthweight and production for life.
