Evaluation Of Supplementing Whole Cottonseed Within Feedlot Rations During The Stockerphase Of Production With The Goal Of Increasing Average Daily Gain, Emily Lauren Cook

Masters Theses & Specialist Projects

Beef calves are weaned at 6-months of age and enter the stocker phase of beef production. Stocker producers have the primary goal of adding weight inexpensively to increase profit on weaned calves. Whole cottonseed is an inexpensive feed ingredient that is popularly top-dressed within dairy and finishing beef diets and is high in protein and energy. During three periods lasting 50-days (fall 2019, fall 2020, and spring 2020), freshly weaned calves were placed on a finishing ration with the goal of increasing average daily gain. Base rations were calculated at 25% tall fescue hay, 23% corn, and 52% distillers’ solubles. …

Detection And Quantitation Of Tetracycline Antibiotics In Agricultural Swine Wastes, Ali Jamal Abdulrheem

Masters Theses & Specialist Projects

The spread of tetracyclines through agricultural systems is causing the present bacteria to develop antibiotic resistance. The spread of this bacteria, as well as the tetracycline antibiotics in the environment is dangerous because these antibiotics pose health hazards for humans. The overuse of antibiotics, which are added to livestock feed, results in the antibiotics being released into the environment via animal feces. In this research, we have attempted to design an analytical method to isolate antibiotics from agricultural wastes with subsequent detection using liquid chromatography and mass spectrometry (LC-MS). The antibiotics investigated in this study were tetracycline, chlortetracycline, and oxytetracycline. …

Swine Breed Differences In Agglutination Titers Following Vaccination With Sheep Red Blood Cells And Pasteurella Multocida (Serotype A), Kenneth Stalder

Masters Theses & Specialist Projects

An investigation into the genetic differences in the humoral immune response of swine following vaccination with a sheep red blood cell solution (SRBC) and a commercially prepared Pasteurella multocida (serotype A) bacterin (PmA) was conducted on a total of 268 pigs from two individual trials. This study was also conducted to evaluate the humoral immune response of pigs to a non-pathogen (SPEC) and a known pathogen to swine (PmA). The pigs used in the first trial were from 22 litters born between January 1991 and July 1991. The pigs consisted of Hampshire x Yorkshire (n=114), purebred Yorkshire (n=70) and Hampshire …

Performance & Carcass Traits Of Swine Of Four Different Phenotypes & Three Usda Grades, Jon Althaus

Masters Theses & Specialist Projects

The purpose of this study was to compare the performance and carcass characteristics of swine of four different phenotypes and three USDA grades.

Hogs were placed into phenotypic groups of 24 each and penned by group. These pens were ideal, cutability, light muscled, fat, VS US and US The hops were fed a 16% corn and soybean meal ration fortified with appropriate minerals and vitamins. They were housed in a total confinement curtain-sided Kentucky plan building with a partially slatted floor. The hogs were weighed at 6-week intervals throughout the project to monitor average daily gain and pen feed efficiency. …

Comparisons Of Performance & Carcass Traits Of Littermate Boars & Barrows, Hiromi Hirano

Masters Theses & Specialist Projects

The purpose of this study was to determine differences between littermate boars and barrows for performance and carcass traits in the Iowa and Northeast Iowa Swine Testing Stations. Data were obtained from 917 litters including 1,804 boars and 917 barrows. The data included 1,086 boars and 581 barrows from the Iowa Station at Ames, Iowa, and 718 boars and 336 barrows from the Northeast Iowa Station at New Hampton, Iowa. The Iowa Station data were obtained over a period of 12 seasons from the fall of 1979 through the fall of 1985, and the data from the Northeast Iowa Station …

The Antibody Production By Swine In Response To Sheep Red Blood Cells, Deborah Seymour

Masters Theses & Specialist Projects

Two experiments were conducted to study the antibody response of pigs challenged with the general antigen sheep red blood cells (SRBC).

In one experiment SRBC's were injected at one of four sties: intramuscularly into the neck, intramuscularly into the ham, subcutaneously into the fore flank or rear flank. These treatments were repeated four weeks later. The antibody responses to the four treatments were determined by microtiter and analyzed statistically. No significant (P> 0. 10) differences were found among responses to the four treatments during the fourth and eighth weeks after injections, but a significant (P<0.05) difference was found during the fifth week among all four groups. Coefficients of correlation showed highly significant (P<.0.01) relationships between SRBC antibody titer during the fourth week after injections and increase in weight of test animals from the beginning of the study until slaughter.

In a second experiment pigs …

Comparison Of Iron Supplements For The Prevention Of Anemia In Young Pigs, Steve Hieronymus

Masters Theses & Specialist Projects

Crete Koate^® product originally intended to be utilized for absorbing excess moisture and reducing knee abrasions of baby pigs raised in confinement, was tested as a hematinic for young pigs. Four treatments were studied: (1) T-NI, pigs receiving no iron; (2) T-IS, pigs receiving a 2 ml intramuscular injection of iron-dextran at 2 days of age; (3) T-CK, pigs raised in pens treated daily with Crete Koate; (4) T-ISCK, pics receiving an intramuscular injection of iron-dextran on day 2 whose pens received daily treatments of Crete Koate. Hemoglobin levels were used as an indicator of iron status in the …

Iron Requirement Of Pigs Farrowed In Metal Farrowing Stalls, Rebecca Walker

Masters Theses & Specialist Projects

Pigs farrowed and reared in metal farrowing stalls were studied to determine the need for iron. Three treatments were studied, namely—T-O (pigs given no iron injection), T-1 (pigs given 1 iron-dextran injection at 2 days of age) and T-2 (pigs given 2 injections of iron-dextran, the first at day 2 and the second at day 7). Hemoglobin levels were analyzed to determine the incorporation of iron in the bloodstream in the form of hemoglobin. Pig weights were used as a measure of production.

The hemoglobin levels did not differ (p>0.1) among the 3 treatments at birth, 4 days, 6 …
