Use Of Ddgs As The Primary Source Of Supplemental Crude Protein In Calf Receiving Diets, Robbi H. Pritchard, Donald L. Boggs
Use Of Ddgs As The Primary Source Of Supplemental Crude Protein In Calf Receiving Diets, Robbi H. Pritchard, Donald L. Boggs
South Dakota Beef Report, 2006
This experiment was designed to determine whether DDGS could be used as the primary source of supplemental crude protein in receiving calf diets. Diets included 45% oat hay and rolled corn. The control diet included 11.8% SBM as the source of supplemental crude protein. The DDGS was fed at 18.9% of diet replacing SBM. There was 1.3% SBM included in the DDGS diets. Diets were formulated for 13% CP and 48 Mcal/cwt NEG. The 47-d experiment began at arrival at the feedlot and involved 294 steer calves (604 lb). Calf gains (2.49 vs 2.54 lb/d) and F/G (5.76 vs 5.61) …
Evaluation Of Hoof Circumference To Predict Birth Weight, R. J. Pruitt, K. Van Der Wal, M. Britt
Evaluation Of Hoof Circumference To Predict Birth Weight, R. J. Pruitt, K. Van Der Wal, M. Britt
South Dakota Beef Report, 1995
Records from 81 calves showed that hoof circumference is an unreliable predictor of birth weight. A hoof tape predicted only 25.9% of birth weights within 2 Ib of actual birth weight. For 29.6% of the calves the error in predicting birth weight was over 10 Ib.
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.
Preweaning Processing Anthelmintic Treatment And Post Weaning Effects Of Sulfamethazine Based Medications On Performance Traits And Oocyst Shedding In Weaned Calves, R.H. Pritchard, J.U. Thomson, M.A. Robbins
Preweaning Processing Anthelmintic Treatment And Post Weaning Effects Of Sulfamethazine Based Medications On Performance Traits And Oocyst Shedding In Weaned Calves, R.H. Pritchard, J.U. Thomson, M.A. Robbins
South Dakota Beef Report, 1990
Two trials were conducted to evaluate antibiotic therapies for feeder calves originating in western South Dakota. In Trial 1, processing-anthelmintic treatment 28 days before weaning reduced ranch gains and provided no advantage in feedlot gains when calves were reprocessed. Processing included deworming, grubicide treatment, implanting and vaccination. Sulfamethazine medication caused transient improvements in feedlot performance during the feedlot receiving period in both trials. Supertherapeutic treatment with AS 700 offered no advantage in feedlot performance over therapeutic feeding in these calves. Sulfamethazine exposure suppressed coccidia oocyst shedding and appears to be an effective means of controlling coccidiosis and shipping fever complex …
Effect Of Early Weaning On Feedlot Performance And Carcass Characteristics Of High Growth Potential Feeder Calves, R.H. Pritchard, M.A. Robbins, D.H Gee, R.J. Pruitt
Effect Of Early Weaning On Feedlot Performance And Carcass Characteristics Of High Growth Potential Feeder Calves, R.H. Pritchard, M.A. Robbins, D.H Gee, R.J. Pruitt
South Dakota Beef Report, 1988
Steer and heifer calves produced at Ft. Meade were used to evaluate early weaning and accelerated feeding as a management tool when retaining ownership of calves. Calves were weaned at 5 1/2 (EM) or 7 mo (NW) of age and started immediately on a 60% grain feeding program. Slaughter dates represented mean calf ages of 385 or 425 days and days on feed ranged from 179 to 257 days. Range conditions were good and early weaning had little effect on calf weight at any point in the feeding period. Feeding high grain diets to EW calves did not have any …
