Comparison Of Yearling Steer Gains In Early Summer Under Season-Long Native, Season-Long Crested Wheatgrass And June-Deferred Native Grazing Systems, P.S. Johnson, J. J. Wagner, M. J. Goetz, J. Cantrell
South Dakota Beef Report, 1989
Season-long native, season-long crested wheatgrass and June-deferred native grazing systems were compared with regard to average daily gains, gains per acre and total gains. Due to drought conditions, the typical 4-month spring-summer season was reduced to a season of approximately 2 months beginning in June. Few differences were detected between the systems for ADG in each month or over the season. Gains per acre were greatest (P<.05) on crested wheatgrass pastures (33.75 Ib/acre), but no differences were detected between native pastures (1 0.61 -1 6.61 Ib/acre) regardless of whether they had been grazed for 2 months or one (using similar stocking rates). This study indicates that, using weight gain data from 1989 and a 2-month grazing season, the greatest potential gain for the season is realized with a system where cattle graze crested wheatgrass in June and native pastures in July. If this system was applied on 320 acres crested wheatgrass and 640 acres excellent condition native pasture, it would have the potential to produce approximately 23,196 Ib of gain on yearling steers compared with season-long (June-July) production of 9,408 Ib on @I0 acres and 14,112 Ib on 960 acres native pasture.
Effect Of Late Season Protein And Energy Supplementation On Performance Of Yearling Steers Grazing Mixed Native Range Or Cool Season, Crested Wheatgrass Pastures, J.J. Wagner, P.S. Johnson, J. Cantrell
Effect Of Late Season Protein And Energy Supplementation On Performance Of Yearling Steers Grazing Mixed Native Range Or Cool Season, Crested Wheatgrass Pastures, J.J. Wagner, P.S. Johnson, J. Cantrell
South Dakota Beef Report, 1989
Seventy-two yearling, black baldy steers were utilized in a grazing experiment to study the effect of late summer, early fall protein (2.33 Ib., 40% all natural, fed each Monday, Wednesday and Friday) or energy (4.4 Ib. corn fed daily) supplementation on average daily gain. Two pasture types, mixed native range and crested wheatgrass, were also examined. Cattle were purchased in May as part of a larger group and gained an average of 2.16 Ib. per head daily prior to initiation of the study on September 9, 1988. Average daily gain was significantly greater (P = .012) for cattle grazing crested …
