Ruminant Nutrition: Beef: Forages and Grazing
The objective of this study was to evaluate self-fed byproducts on pasture reared finishing cattle. Major effects studied were animal performance, carcass traits and fatty acid (FA) profile with specific emphasis on conjugated linoleic acid (cis-9, trans-11–18:2; CLA). Eighty-two crossbred yearling steers were utilized in a 2 × 2 factorial design with implanted and non-implanted cattle fed eith...
متن کاملLevels of Supplementation for Grazing Beef Heifers
The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consis...
متن کاملRyegrass Swards Compared with Perennial Ryegrass Swards on the Performance and Carcass Quality of Grazing Beef
An experiment investigated whether the inclusion of chicory (Cichorium intybus) in swards grazed by beef steers altered their performance, carcass characteristics or parasitism when compared to steers grazing perennial ryegrass (Lolium perenne). Triplicate 2-ha plots were established with a chicory/ryegrass mix or ryegrass control. Forty-eight Belgian Bluecross steers were used in the first gra...
متن کاملForages and Pastures: Grazing and Forage Management
Pastures located on southern Iowa cow/calf farms, from 8 to 125 ha in size, were used to evaluate the effects of microclimate, shade, botanical composition, and other pasture characteristics influencing the temporal/ spatial distribution of cattle within and outside streamside zones of pastures. Cows were Angus and Angus-cross on 4 of the farms, and Mexican Corriente on the remaining farm. Duri...
متن کاملASAS/ADSA Forages and Pastures: Grazing and Alternative Forages
An experiment was conducted to determine animal performance and gain/ha of beef steers (mean initial wt.: 241 kg) grazing a conventional sorghum x sudan hybrid (C) versus its near isogenic brown midrib (BMR) variety. The experiment was conducted during the summers of 1999 and 2000 in the Texas Panhandle. During both summers 8 pasture plots (2.2 ha) were blocked by location and randomly assigned...
