Stocking System Effects On Cattle Performance, Forage, And Soil Properties Of Cool-Season Pastures, Margaret Warter Dunn Jan 2013

Stocking System Effects On Cattle Performance, Forage, And Soil Properties Of Cool-Season Pastures, Margaret Warter Dunn

Graduate Theses and Dissertations

Increasing stocking density and rotation frequency of grazing cattle may improve forage yield and quality and soil carbon content, but may reduce livestock performance and forage persistence and compact soil. Sixty mature August-calving Angus cows (Bos taurus L.; mean body weight (BW), 585 ± 9.9 kg) were allotted to six 4.05-ha cool-season pastures to graze by rotational (RS), strip (SS), or mob (MS) stocking from May through September for two years (2010-2011). Stocking density averaged 16 000, 80 000, and 350 000 kg BW * ha-1 * d-1 in RS, SS, and MS pastures, respectively. Daily live forage allowance was equal ...


Performance, Carcass Traits And Fatty Acid Profiles Of Yearling Beef Cattle Supplemented With Self-Fed Byproducts On Pasture, Daniel Dean Kiesling Jan 2013

Performance, Carcass Traits And Fatty Acid Profiles Of Yearling Beef Cattle Supplemented With Self-Fed Byproducts On Pasture, Daniel Dean Kiesling

Graduate Theses and Dissertations

Due to rising costs of conventional feedstuffs, more research has been focused on feeding non-conventional feedstuffs, such as byproducts of ethanol production or further processing of grains (i.e. soyhulls). Because of the health benefits of conjugated linoleic acid (CLA) shown in studies on laboratory animals, consumer interest in foods enriched with CLA has increased. The objective of this study was to investigate the effects of finishing yearling market steers on pasture supplemented with combinations of self-fed byproducts on live animal performance, carcass traits and fatty acid profiles; specifically CLA. British and Continental crossbred beef steers (n = 162, BW = 404 ...
