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
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 …
