Evaluation Of The Virulence Potential Of Avian Pathogenic Escherichia Coli Isolated From Broiler Breeders With Colibacillosis In Mississippi, Jiddu Joseph
Theses and Dissertations
Avian pathogenic Escherichia coli (APEC) is a bacterium that is responsible for colibacillosis in birds. However, information about broiler breeder APEC isolates is limited, but the data is critical due to the transfer of this bacteria down the production pyramid to progenies resulting in high mortality. Therefore, we evaluated the phenotypic virulence characteristics of 28 isolates using embryo lethality and day-old chick challenge assays. Also, the in vitro adhesion and invasion potential of selected nine isolates were identified. Results showed more than 1/3rd of the isolates were highly virulent and the virulence increased as the number of virulence-associated genes …
Evolution And Epidemiology Of Channel Catfish Virus (Ccv), Arun Venugopalan
Evolution And Epidemiology Of Channel Catfish Virus (Ccv), Arun Venugopalan
Theses and Dissertations
Channel catfish virus disease (CCVD) is the principal viral disease in the United States catfish industry. The CCVD is caused by channel catfish virus (CCV), with mortality reaching up to 100% in fingerlings. CCV is assigned taxonomically to the family Alloherpesviridae, genus Ictalurivirus, species Ictalurid herpesvirus 1 (IcHV-1). To date, virulence, immunogenicity, and genome plasticity of the CCV field isolates have not been investigated. Three genotypes of CCV (IcHV-1A, IcHV-1B, and BCAHV) were identified using restriction fragment length polymorphism (RFLP) analysis. Virulence assessment of three representative isolates of RFLP groups suggests that IcHV-1B (pooled survival [mean ± SE]: 58.3% ± …
Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Theses and Dissertations
Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …
Effect Of The Use Of Amaranth Leaf Flour In The Development Of A Diet For Guinea Pigs, Verónica Del Rocío Guerrero Carrera
Effect Of The Use Of Amaranth Leaf Flour In The Development Of A Diet For Guinea Pigs, Verónica Del Rocío Guerrero Carrera
Theses and Dissertations
This study was carried out in the San Clemente community. The objective was to analyze the effect of using amaranth leaf flour in the creation of a diet for guinea pigs. The field work was done over a period of 12 months and was done in two phases: Development of the diet: this was done by growing the amaranth, cutting it, and dehydrating it until flour was obtained. Then, it was mixed into the diet in accordance with the pre-determined formula along with the other respective materials. Handling of guinea pigs: This was done in the shed of the San …
Biochemical And Molecular Nutrition Blocks As Dietary Supplements In Llamas (Lama Glama) In The Last Third Of The Gestation Period Of The Ceac, Janette Illanes Callejas
Biochemical And Molecular Nutrition Blocks As Dietary Supplements In Llamas (Lama Glama) In The Last Third Of The Gestation Period Of The Ceac, Janette Illanes Callejas
Theses and Dissertations
The present work consisted in the use of biochemical and molecular nutrition blocks (BMN) in llamas during the last third of the gestation period, at the Agricultural Experiment Center of Condori (CEAC), located 49 km north of the city of Oruro, and 12 km north of the Caracollo population, in the province of Cercado. For this research work, we used 20 pregnant llamas in the last third of their gestation period, between the ages of 2 and 3 years old, 10 of which belonged to the Khara breed, and 10 to the Thampulli breed. Two corrals of 7 x 7 …
Effect Of Bulbourethrectomy And Collection Frequency On Macro- And Microscopic Characteristics Of Llama (Lama Glama) Ejaculate, Víctor Efrain Gonzáles Vargas
Effect Of Bulbourethrectomy And Collection Frequency On Macro- And Microscopic Characteristics Of Llama (Lama Glama) Ejaculate, Víctor Efrain Gonzáles Vargas
Theses and Dissertations
This study occurred in the Rural Academic Unit-Tiahuanaco installations, of the Bolivian Catholic University-La Paz, Bolviia, with the objective of evaluating macro- and microscopic characteristics of sperm ejaculation from bulbourethrectomized llamas. Six q'ara-variety male llamas of 3, 4, and 5 years of age were used over 8 weeks during which they were fed with natural and cultivated pastures. Ejaculate was collected with an artificial vagina with stimulation (libido) of male llamas by female llamas, for macro- and microscopic evaluation (volume, pH, color, appearance, motility, concentration, and sperm vitality). The results obtained were: average volume of 0.55[+or-]0.36 ml, with a CV …
Determination Of The Protein Fraction And Presence Of Antibodies In The Seminal Fluid Of Llama (Lama Glama), Francisco Flores Lopes
Determination Of The Protein Fraction And Presence Of Antibodies In The Seminal Fluid Of Llama (Lama Glama), Francisco Flores Lopes
Theses and Dissertations
At an international level, Bolivia possesses the largest population of llamas followed by Peru. This makes our country a power, in this renewable resource, to create and generate economic development primarily for the quality of llama meat which has nutritional properties superior to other species of animals used for food. The development of the investigation of llamas in our country has not been very far-reaching. In other countries, advances have been made for quite some time, specifically in the area of reproduction, which presents problems in bringing about an intensive repopulation due to the unique characteristics of llama copulation and …

Detection Of Antibodies Against Brucella Abortus In Bovine, Celso Arturo Moreno Paredes
Theses and Dissertations
The present investigation was made in the Laboratories of microbiology of the Ability of Cattle Sciences of the Polytechnic Superior School of Chimborazo, with samples obtained in the Municipal Camal Riobamba and the Community of Tunshi San Nicolás. The incidence of Brucellosis was analyzed in six more important cattle areas of the county using the antigens Brucella abortus and Rosa of Flare. The experimental units were obtained under a systematic sampling. The experiment had a duration of 4 months. The experimental results underwent the following analyses: variance, percentages, stockings, standard deviation, limit for the estimate error. According to carried out …
