Pasture size effects on the ability of off-stream water or restricted stream access to alter the spatial/temporal distribution of grazing beef cows
Autor: J J, Bisinger, J R, Russell, D G, Morrical, T M, Isenhart
Publikováno v: Journal of animal science. 92(8)
For 2 grazing seasons, effects of pasture size, stream access, and off-stream water on cow distribution relative to a stream were evaluated in six 12.1-ha cool-season grass pastures. Two pasture sizes (small [4.0 ha] and large [12.1 ha]) with 3 manag

Effects of pasture management and off-stream water on temporal/spatial distribution of cattle and stream bank characteristics in cool-season grass pastures
Autor: K A, Schwarte, J R, Russell, D G, Morrical
Publikováno v: Journal of animal science. 89(10)
A 2-yr grazing experiment was conducted to assess the effects of grazing management on cattle distribution and pasture and stream bank characteristics. Six 12.1-ha cool-season grass pastures in central Iowa were allotted to 1 of 3 treatments: continu

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

Publikováno v: Journal of animal science. 81(11)
A multistate cooperative study was conducted to study the current issue of tail length in docked lambs and its relationship to incidence of rectal prolapse. A total of 1,227 lambs at six locations were randomly allocated to two or three tail dock tre

Reproductive performance of ewes exposed to vasectomized rams before breeding and forced exercise before lambing
Autor: D. G. Morrical, R.E. Hudgens, Dennis M. Hallford
Publikováno v: Theriogenology. 18:663-669
Twenty days before a regular fall breeding season, 93 mature Rambouillet ewes were randomly allotted to one of two groups to examine the response of cycling females exposed to sterile rams. Six vasectomized rams were joined with 46 ewes during the 20
