Comparison Of Production Efficiencies When Calves Are Fed In South Dakota Or Texas, R. H. Pritchard, R. L. Preston
Comparison Of Production Efficiencies When Calves Are Fed In South Dakota Or Texas, R. H. Pritchard, R. L. Preston
South Dakota Beef Report, 1992
South Dakota's reputation for harsh winters is frequently cited as a limitation to our competitiveness in cattle feeding. To help quantify the impact of climate on cattle feeding, heifers produced in western South Dakota were fed in eastern South Dakota or in the Texas panhandle. Heifer calves were obtained from two ranches, assembled at SDSU, and sorted into three similar groups. Group 1 remained at the SDSU feedlot, Group 2 was shipped half-way to Texas and returned to SDSU, and Group 3 was sent on to Texas for feeding. These groups allow consideration of climate and transit stress on feedlot …
South Dakota Retained Ownership Demonstration, J. J. Wagner, T. B. Goehring, D. L. Boggs, L. W. Insley
South Dakota Retained Ownership Demonstration, J. J. Wagner, T. B. Goehring, D. L. Boggs, L. W. Insley
South Dakota Beef Report, 1992
Four hundred nineteen steer calves representing 57 cow-calf producers were consigned to a custom feedlot in mid-October. Cattle were fed in one of three pens. One pen of calves was fed a starter program for 20 days followed by a moderate roughage growing diet for 84 days before they were switched to a high energy finishing diet (TWO). The other two pens were fed a starter program for 20 days followed by a moderate roughage growing diet for 14 days before they were switched to a high energy finishing diet. Cattle were sorted into one of these two pens on …
An Update On Retained Ownership: Case Study Of Calves Born At The Antelope Range Livestock Station, D. M. Marshall
An Update On Retained Ownership: Case Study Of Calves Born At The Antelope Range Livestock Station, D. M. Marshall
South Dakota Beef Report, 1992
An update to a previous report on the case history of retained ownership in the Antelope Range Livestock Station herd is provided. Calves born in 1990 and 1991 were placed in a custom feedlot following weaning and the profitability of postweaning feedlot performance was estimated. Retaining ownership through slaughter, as opposed to selling calves at weaning, resulted in additional estimated profits of $51.27 and $107.82 per head (excluding interest on calf) for the 1990-born and 1991-born calf crops, respectively.
Effect Of Lutylase Or Bovilene On Conception Rate To Artificial Insemination Of Heifers, T. B. Goehring, D. M. Marshall
Effect Of Lutylase Or Bovilene On Conception Rate To Artificial Insemination Of Heifers, T. B. Goehring, D. M. Marshall
South Dakota Beef Report, 1992
Calving records from 306 two-year-old heifers were used to compare the effect of Lutylase or Bovilene on first-service conception rate as part of an estrus synchronization and artificial insemination program. There was no difference (P=.91) between products in the percentage of heifers conceiving to artificial insemination following estrus synchronization.
Effect Of Bull Exposure On Reproductive Performance Of First-Calf Heifers Bred By Natrual Service, T. B. Goehring, H. L. Miller, C. R. Quinn, R. L. Quinn
Effect Of Bull Exposure On Reproductive Performance Of First-Calf Heifers Bred By Natrual Service, T. B. Goehring, H. L. Miller, C. R. Quinn, R. L. Quinn
South Dakota Beef Report, 1992
Ninety-four spring calving, first-calf heifers were allotted to one of two treatment groups, control or bull exposed, to study the effect of bull exposure early postpartum on rebreeding performance when bred by natural service. Bull exposure early postpartum had no effect on pregnancy rate. However, bull exposure unexpectedly increased the subsequent calving interval by 9 days (P<.05) and delayed the average calving date by 7 days (P<.05). Under the conditions of this study in which heifers were in condition score 5 or better at calving and bred by natural service, bull exposure early postpartum did not improve reproductive performance.
Effect Of Straw And Newspaper Bedding On Cold Season Feedlot Performance In Two Housing Systems, C. P. Birkelo, J. Lounsbery
Effect Of Straw And Newspaper Bedding On Cold Season Feedlot Performance In Two Housing Systems, C. P. Birkelo, J. Lounsbery
South Dakota Beef Report, 1992
Two hundred seventy-three crossbred steer calves were fed until slaughter (November through May, 189 days) in either semi-confinement (partial overhead shelter, 88 sq. ft. per steer, concrete pen surface) or conventional open lots (windbreak, 448 sq. ft. per steer, dirt surface with mound). Within each housing system, cattle were provided with no bedding or bedding in the form of oat straw or shredded newspaper. Bedding was provided in amounts necessary to maintain a relatively dry, manure-free area large enough for all cattle to lay down at the same time. There were no interactions between housing systems or bedding treatments (P …
Limiting Intake Of Finishing Diets By Restricting Access Time To Feed And The Interaction With Monensin, C. P. Birkelo, J. Lounsbery
Limiting Intake Of Finishing Diets By Restricting Access Time To Feed And The Interaction With Monensin, C. P. Birkelo, J. Lounsbery
South Dakota Beef Report, 1992
One hundred seventy-six yearling steers were randomly allotted to 16 pens and fed ad libitum or restricted amounts of finishing diets with or without monensin. lntake of the restricted cattle was limited by allowing only 6 to 7 hours access time to feed per day. All cattle were fed once daily. Monensin and restricting access time reduced feed intake by 5.6% and 7.9% (P<.01), respectively. lntake tended to be lowest for restricted cattle fed monensin (P=.13). lntake of restricted cattle as a percent of ad libitum intake varied greatly during the study. This may have contributed to the 7% reduction in daily gain of the restricted-monensin fed cattle and the fact that only nonsignificant trends toward improved feed efficiency due to intake restriction were found (P=.13). Factors affecting rate of feed intake must be considered if limited access time is to be used successfully to improve feed efficiency.
Optimum Monensin Levels In Receiving Diets For Newly Weaned Calves, R. H. Pritchard, J. U. Thomson
Optimum Monensin Levels In Receiving Diets For Newly Weaned Calves, R. H. Pritchard, J. U. Thomson
South Dakota Beef Report, 1992
This research addressed the effects of dietary monensin on the performance and health of steer calves weaned and shipped directly to the feedlot. Feedlot receiving diets were based on corn silage and contained 0, 10, 20, or 30 g/ton monensin. Calves were allowed ad libitum access to feed for 85 days to determine the effects of monensin level on dry matter intake, average daily gain, and fecal shedding of coccidia oocysts. Higher levels of monensin caused decreases (P<.05) in dry matter intake during the initial feeding period. Gains were not affected by monensin during this period and as a result feed efficiency was improved (P<.05) when diets contained 20 or 30 g of monensin per ton. Cumulative 85-day feedlot performance was not affected by treatment. Over 90% of all calves were shedding coccidia oocyst when they arrived in the feedlot. The number of calves shedding oocysts was consistently reduced by monensin after 18 days postweaning.
Combination Of Synovex-S¹ And Finaplix-S² For Yearling Steers, J. J. Wagner, R. H. Pritchard
Combination Of Synovex-S¹ And Finaplix-S² For Yearling Steers, J. J. Wagner, R. H. Pritchard
South Dakota Beef Report, 1992
Two hundred seventy-seven crossbred yearling steers (719 Ib) were utilized in a 3-year study to determine the effect of combinations of Synovex-S and Finaplix-S on daily gain and carcass merit. Treatments included no implant (C), implanted with Synovex-S on day 1 and Synovex-S on about day 60 (SS), and implanted with Synovex-S on day 1 and the combination of Synovex-S and Finaplix-S on about day 60 (SSF). In year 1, all steers were slaughtered after 124 days on feed. In year 2, steers were slaughtered after 120, 134, or 148 days on feed. In year 3, steers were slaughtered after …
Implant Combinations And Reimplanting Strategies For Yearling Steers Fed High Concentrate Diets, R. H. Pritchard, M. A. Robbins, D. H. Gee
Implant Combinations And Reimplanting Strategies For Yearling Steers Fed High Concentrate Diets, R. H. Pritchard, M. A. Robbins, D. H. Gee
South Dakota Beef Report, 1992
Crossbred yearling steers were used to determine the relative efficacy of specific anabolic implant combinations and sequences on feedlot performance and carcass traits. Steers were fed a high concentrate finishing diet for 112 days. lmplanting was done on days 1 and 42 of the feeding period. lmplanting improved (P < .05) average daily gain (ADG) 22% and feed efficiency 15%. Implant treatment generally increased dry matter intake. Lmplanting increased (P<.05) the rib eye area of carcasses 6.5% and tended to cause a reduction in percentage choice carcasses. The percentage of abscessed implants ranged from < 1 % to 10%, depending on the type of implant used even though implant needles were disinfected between each use.
Breeding System Effects On Production Efficiency Through Weaning-Preliminary Results, D. M. Marshall
Breeding System Effects On Production Efficiency Through Weaning-Preliminary Results, D. M. Marshall
South Dakota Beef Report, 1992
Preliminary results are presented on production efficiency for a comparison of two-breed rotational crossbreeding to the terminal phase of a rotational-terminal combination system with Charolais as the terminal sire breed. The breeding system comparisons were made within each of three types of dam: Simmental x Hereford, Angus x Hereford, and Tarentaise x Hereford. The two breeding systems had similar average values for dam size, condition score, and feed ME through weaning. Results indicate an increase for terminal matings compared to rotational matings in terms of weaning weight and efficiency ratio (calf weaning weight/dam and calf feed ME) within the Angus …
Effect Of Source And Level Of Supplemental Protein On Performance Of Postpartum Range Cows, M. C. Namminga, R. J. Pruitt
Effect Of Source And Level Of Supplemental Protein On Performance Of Postpartum Range Cows, M. C. Namminga, R. J. Pruitt
South Dakota Beef Report, 1992
Two postpartum grazing trials were conducted from early March to mid May in consecutive years to determine the effects of supplemental rumen escape protein on the performance of spring calving beef cows grazing native range. Simmental x Angus cows were allotted within 7 to 14 days of calving to three supplement treatments formulated to provide equal amounts of energy from corn, soybean meal, and a combination of blood meal and corn gluten meal. Cows supplemented with corn lost more weight than cows supplemented with soybean meal. Supplemental escape protein did not improve weight gains over the soybean meal supplement. Supplemental …
Effects Of Level Of Concentrate And Forage Availability On The Performance Of Beef Cows Grazing Winter Range, M. C. Namminga, R. J. Pruitt, C. A. Tusler, P. S. Johnson
Effects Of Level Of Concentrate And Forage Availability On The Performance Of Beef Cows Grazing Winter Range, M. C. Namminga, R. J. Pruitt, C. A. Tusler, P. S. Johnson
South Dakota Beef Report, 1992
Two winter grazing trials were conducted on consecutive years to determine the effect of level of concentrate supplement and amount of forage available on performance of cows grazing dormant winter range. Simmental x Angus cows were fed concentrate supplements containing combinations of corn and soybean meal at either high, medium or low levels. Supplements were formulated to provide .7 Ib of crude protein during year 1 and .51 Ib of rumen degradable crude protein in year 2. Two pastures with differing amounts of available forage were grazed each year. In year 1, the amount of available forage had a greater …
In Vitro Analysis Of Drought Stressed, Chopped Sunflower Heads As A Protein Supplement For Cattle Grazing Corn Crop Residues, D. U. Thomson, R. H. Pritchard
In Vitro Analysis Of Drought Stressed, Chopped Sunflower Heads As A Protein Supplement For Cattle Grazing Corn Crop Residues, D. U. Thomson, R. H. Pritchard
South Dakota Beef Report, 1992
The suitability of drought stressed, chopped sunflower heads as an energy and crude protein supplement to low quality forages was evaluated using in vitro fermentation techniques. Sources of supplemental crude protein used in comparisons were drought stressed, chopped sunflower heads, soybean meal, soybeans, and urea. These crude protein sources were added to cornstalks to produce substrates containing 6, 8, 10, 12, and 15% crude protein. Observed fermentable dry matter was higher than the estimated fermentable dry matters, indicating positive associative effects of crude protein level. Similar differences in observed and estimated fermentable dry matters occurred among soybean meal, soybean, and …

Chaps Summary For South Dakota, 1991, D. L. Boggs
South Dakota Beef Report, 1992
Calving distribution and calf performance data were summarized from the CHAPS (Cow Herd Appraisal of Performance Software) analyses of 61 South Dakota cow herds. CHAPS uses beef cow weaning weight records to calculate adjusted 205-day weights and ratios, keep lifetime production records on cows, calculate Most Probable Producing Ability estimates for cows, produce a sire summary and analyze production according to cow age and 21 -day calving periods. The 1991 summary represents 6,196 cows for an average of 102 cows per herd. The herds ranged in size from 19 to 277 head. The average midpoint of the calving season for …
