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 …


Moderate Versus High Protein Diets For Finishing Yearling Steers, J.J. Wagner, R. Hansen Jan 1989

Moderate Versus High Protein Diets For Finishing Yearling Steers, J.J. Wagner, R. Hansen

South Dakota Beef Report, 1989

Sixty-four yearling crossbred steers (864 Ib) were utilized to study moderate versus high protein finishing diets. Diets were formulated to contain 11.25 or 12.25% crude protein on a dry matter basis. Differences observed for all performance and carcass traits were not significant. Steers on the 11.25 and 12.25% crude protein diets consumed 22.29 and 22.26 Ib dry matter per head daily, gained 2.83 and 2.90 Ib per head daily and required 7.91 and 7.69 Ib dry matter per pound of gain, respectively. Diets formulated to contain 11.25% crude protein appear adequate for finishing heavy yearlings.
