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. …

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 …

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 …
