Autor: Larry L. Berger, R.K. Knipe, Dan B Faulkner, D. R. Strohbehn, D. F. Parrett, A.J. Miller
Publikováno v: The Professional Animal Scientist. 17:295-302
Financial, economic, and biological data from cow-calf producers participating in the Illinois and Iowa Standardized Performance Analysis programs were analyzed. Data were collected from 1996 to 1999; each herd-year represented one observation. The d

Effects of stocking rate and corn gluten feed supplementation on performance of young beef cows grazing winter-stockpiled tall fescue-red clover pasture
Autor: R, Driskill, J R, Russell, D R, Strohbehn, D G, Morrical, S K, Barnhart, J D, Lawrence
Publikováno v: Journal of animal science. 85(6)
A winter grazing experiment was conducted to evaluate the effects of stocking rate and corn gluten feed supplementation on forage mass and composition and the BW and BCS of bred 2-yr-old cows grazing stockpiled forage during winter. Two 12.2-ha block

Grazing and feedlot performance of yearling stocker cattle integrated with spring- and fall-calving beef cows in a year-round grazing system
Autor: N A Janovick, Guretzky, J R, Russell, D R, Strohbehn, D G, Morrical
Publikováno v: Journal of animal science. 83(11)
Effects of calving season and finishing system on forage and concentrate consumption and carcass characteristics of calves were compared. In each of 3 yr, two replicates of three growing and finishing systems were compared including 1) spring calves

Productivity and hay requirements of beef cattle in a Midwestern year-round grazing system
Autor: N A, Janovick, J R, Russell, D R, Strohbehn, D G, Morrical
Publikováno v: Journal of animal science. 82(8)
Our objective was to evaluate a replicated (n = 2) Midwestern year-round grazing system's hay needs and animal production compared with a replicated (n = 2) conventional (minimal land) system over 3 yr. Because extended grazing systems have decreased

Horn fly (Diptera: Muscidae) control on beef cows with permethrin-impregnated ear tags and effect on subsequent calf weight gains
Autor: S. S. Quisenberry, D. R. Strohbehn
Publikováno v: Journal of economic entomology. 77(2)
Permethrin-impregnated ear tags effectively reduced horn flies during the 1981 and 1982 fly seasons by 96 and 99%, respectively. Calves nursing treated cows compared with calves nursing untreated control cows gained 6.7 kg ( P < 0.05) more in 1981 an
