Tree Selection Guide, Cooperative Extension South Dakota State University Apr 1989

Tree Selection Guide, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

The forms or shapes of trees vary from upright and pyramidal to vase-shaped, rounded or irregular. They may be drooping, horizontal or flat. When a tree's branches are held high they are better shade trees, because they provide a canopy of leaves and limbs for shade, while allowing passage and view underneath. Some trees have picturesque growth, giving interesting character, silhouette and winter effect.

Grazing Public Lands In Western South Dakota - What's It Worth?, M. K. Beutler Jan 1989

Grazing Public Lands In Western South Dakota - What's It Worth?, M. K. Beutler

South Dakota Beef Report, 1989

South Dakota has relatively few acres of public rangeland when compared to other western states. However, public grazing in South Dakota can have a major impact on local area economies in which public grazing occurs. Total harvested AUMs have declined over the study period. The total value of public land grazing has climbed mainly due to higher cattle prices. In 1988, South Dakota public lands participated in the production of approximately $35 million in gross livestock production. This gross production generated an estimated $66 million in economic activity to the region. In 1988, public lands accounted for an estimated $22.8 …

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 Jan 1989

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.

Feeding Practices In South Dakota Cattle Feedlots, D C. Taylor, J. J. Wagner, R. D. Kappes Jan 1989

Feeding Practices In South Dakota Cattle Feedlots, D C. Taylor, J. J. Wagner, R. D. Kappes

South Dakota Beef Report, 1989

During March 1989, a mail survey of South Dakota cattle feedlot managers was undertaken. The purposes of the survey were to characterize the nature of the cattle feeding industry in South Dakota and to determine the relationships between (i) each of size-of-feedlot and geographic location within the state and (ii) management practices followed by cattle feeders. Direct relationships exist between size-of-feedlot and the following: (1) rate of feedlot utilization in each quarter of the year (P<.10); (2) percentage grain relative to roughage in both growing and finishing diets (P<.10); (3) percentage of feedlots feeding high moisture grain, cracked grain, and ground hay (P<.01); (4) percentage of feedlots using rumen stimulants and growth implants (P<.01); and (5) percentages of managers testing feeds for nutrient composition, using feed scales to control feeding rates, maintaining feed records for separate pens of cattle, and hiring consultants to formulate rations (P<.01). On the other hand, inverse relationships exist between size-of-feedlot and the following: (6) days on feed for heifer calves, yearling steers, and yearling heifers (P<.10); (7) slaughter weight of steers (Pc.10); (8) percentage of home-raised hay and dry grain (P<.10); (9) percentage of feedlots feeding ground grain and unprocessed hay (P<.01); and (10) percentage of feedlots not using feed additives (P<.10). Average days on feed for steer and heifer calves are lower (P<.05) in the West than in other areas of the state. More milo is fed in the West; more barley is fed in the North Central region; and less home-raised corn silage and haylage are fed in the West than in other regions (P<.05).

Effect Of Deccox¹ And Aureomycin² On Performance Of Feedlot Steers During The Receiving Period, J.J. Wagner, R. Hanson Jan 1989

Effect Of Deccox¹ And Aureomycin² On Performance Of Feedlot Steers During The Receiving Period, J.J. Wagner, R. Hanson

South Dakota Beef Report, 1989

One-hundred thirty Angus steer calves (492 Ib) were utilized in a study to determine the effect of feeding Deccox, Aureomycin or a combination of Deccox and Aureomycin on feedlot performance during the feedlot receiving period (29 days). All cattle were fed diets consisting of 50% concentrate on a dry matter basis. No clinical symptoms of respiratory illness or= coccidiosis were observed for any of the cattle in this study. There were no significant differences in average daily dry matter intake due to medication treatment. Feeding Deccox improved (P = .0161) average daily gain about 10.9%. Feeding Aureomycin tended to improve …

Effects Of Restricting Intake On Carcass Traits Of Young Steers, R. H. Pritchard, D. H. Gee, M. R. Robbins Jan 1989

Effects Of Restricting Intake On Carcass Traits Of Young Steers, R. H. Pritchard, D. H. Gee, M. R. Robbins

South Dakota Beef Report, 1989

Feedlot performance and carcass characteristics were compared when steer calves were fed energy dense diets ad libitum (AL) or restricted (RI) to achieve constant growth rates. AL steers grew more rapidly (P.e.10) than RI steers, 2.93 vs 2.74 Ib per head per day. For the period from 98 days to slaughter (AL = 89 days, RI = 99 days), AL steers consumed more dry matter daily than Rl steers. Restricting intake did not affect feed conversions or total dry matter consumed while in the feedlot. Steers were slaughtered at similar final weights. Intake level did not affect carcass weight, rib …

Relationship Of Relative Calving Date Of Beef Heifers To Production Efficiency And Subsequent Reproductive Performance, D.M. Marshall, W. Minqiang, B. A. Freking Jan 1989

Relationship Of Relative Calving Date Of Beef Heifers To Production Efficiency And Subsequent Reproductive Performance, D.M. Marshall, W. Minqiang, B. A. Freking

South Dakota Beef Report, 1989

Relative date of first calving of beef heifers was studied in relation to production efficiency and subsequent reproductive performance. Crossbred heifers were managed in drylot for 1 year, providing for measurement of feed intake through weaning of the first calf. Production traits were evaluated by calving group (CG), where CG1 included records of heifers calving (and calves born) in the first 21 days of the calving season for a particular year, CG2 included those calving from 22 through 42 days and CG3 included those calving after 42 days. Calving groups did not differ significantly for preweaning calf average daily gain, …

Effect Of Dietary Energy Source On Age And Weight At Puberty Of Beef Heifers, G. A. Wilcox, R. J. Pruitt, P. A. Momont, R. H. Pritchard Jan 1989

Effect Of Dietary Energy Source On Age And Weight At Puberty Of Beef Heifers, G. A. Wilcox, R. J. Pruitt, P. A. Momont, R. H. Pritchard

South Dakota Beef Report, 1989

Forty-four Angus and Simmental sired crossbred heifers were fed two diets of differing composition (high forage or high concentrate). Diets were fed to achieve the same average daily gain to evaluate the effect of energy source on age and weight at puberty. Age at puberty, conception rate, pregnancy rate, weight at puberty, glucose and insulin were not significantly different between treatments.

Estrous Synchronization Of Heifers Using Mga And Prostaglandin: Ranch Results, T. B. Goehring Jan 1989

Estrous Synchronization Of Heifers Using Mga And Prostaglandin: Ranch Results, T. B. Goehring

South Dakota Beef Report, 1989

total of 315 yearling heifers were exposed to an estrous synchronization program which consisted of feeding MGA for 14 consecutive days (.5 mg per head per day), followed by a prostaglandin injection 17 days after the last day of MGA feeding. Two hundred forty-seven (78%) of the heifers were detected in heat and artifically inseminated within 5 days after the prostagllandin injection. Response rate ranged from 75 to 84% between ranches and years.

Comparison Of Melengestrol Acetate And Prostaglandin With Two Injections Of Prostaglandin For Estrous Synchronization In Beef Heifers, H. L. Miller, J. J. Wagner, R. L. Hanson Jan 1989

Comparison Of Melengestrol Acetate And Prostaglandin With Two Injections Of Prostaglandin For Estrous Synchronization In Beef Heifers, H. L. Miller, J. J. Wagner, R. L. Hanson

South Dakota Beef Report, 1989

Crossbred beef heifers were used to compare conception rate when synchronizing estrus with melengestrol acetate (MGA) and prostaglandin or two injections of prostaglandin. Melengestrol acetate was fed to one group of heifers for 16 days and prostaglandin injected 16 days after MGA removal or two injections of prostaglandin given 11 days apart in the other group. The MGA group had a higher conception rate (Pc.05) to timed Al, but there was no difference between the two groups for the breeding season. It appears MGA with prostaglandin results in increased conception to a timed insemination.

Evaluation Of Controlled Release Chromic Oxide Boluses And Alkaline Peroxide Lignin As Marker Methods To Determine Forage Intake Of Grazing Ruminants, P.A. Momont, R. J. Pruitt, R. H. Pritchard Jan 1989

Evaluation Of Controlled Release Chromic Oxide Boluses And Alkaline Peroxide Lignin As Marker Methods To Determine Forage Intake Of Grazing Ruminants, P.A. Momont, R. J. Pruitt, R. H. Pritchard

South Dakota Beef Report, 1989

Twenty Hampshire ram lambs used in a digestibility trial were administered controlled release chromic oxide intraruminal boluses to evaluate chromic oxide and alkaline peroxide lignin in combination as potential markers for determining intake of ruminants grazing dormant winter range. Lambs were fed ad libitum mature prairie grass hay and provided .1 Ib crude protein from one of four supplements. The ability to predict fecal output using chromic oxide boluses and diet digestibility using alkaline peroxide lignin were not affected by supplemental treatments. Chromic oxide concentration in the feces was not affected by the time of sampling. The amount of chromium …

Effect Of Methionine, Leucine And Isovaleric Acid On In Vitro Digestibility Of Corn Stover, B. J. Johnson, P. A. Momont, R. J. Pruitt Jan 1989

Effect Of Methionine, Leucine And Isovaleric Acid On In Vitro Digestibility Of Corn Stover, B. J. Johnson, P. A. Momont, R. J. Pruitt

South Dakota Beef Report, 1989

Two-stage in vitro fermentation was used to evaluate the amino acids methionine and leucine and a branched chain volatile fatty acid, isovaleric acid, as potential additives to a grain-urea supplement for cattle consuming corn stover. Dry matter and fiber digestibility were higher for the husks and leaves than the stalk portion of the corn plant. Providing urea as a source of nitrogen improved dry matter and fiber digestibility. There were no improvements in digestibility or fermentation rate with addition of the amino acids or volatile fatty acid evaluated
