Impact Of Relocation And Weaning Stress On The Feedlot Performance Of Steer Calves During The Receiving Period, Simone M. Holt, Robbi H. Pritchard, Timonthy A. Wittig
Impact Of Relocation And Weaning Stress On The Feedlot Performance Of Steer Calves During The Receiving Period, Simone M. Holt, Robbi H. Pritchard, Timonthy A. Wittig
South Dakota Beef Report, 2004
The effect of ranch management on weaning and relocation stress was investigated using spring born steer calves from a single source. Steers on mature (≥ 4 yr of age) dams were weaned at shipment (NW) whiles steers on young (< 4 yr of age) dams had been weaned and on feed at the ranch for 1 mo prior to shipment (PW). At shipment tympanic temperature (TT) loggers, an indicator of body temperature, were placed in 13 steers from each management group at shipment. Steers were transported together to the SDSU Research Feedlot (365 mi). Body weight after 21 d in the feedlot (670 vs 673 lb) and DMI (14.7 vs 14.9 lb) were similar (P > 0.10) between PW and NW steers, respectively. Average daily gain (2.66 vs 3.17 lb) and feed efficiency (5.53 vs 4.74 lb) were higher (P < 0.05) in NW steers. NW steers recorded higher TT (1.2 ºF; P < 0.05) than PW steers duing loading and transportation from the ranch, indicating a greater initial stress associated with NW. During the first 4 d at the feedlot DMI was lower for NW steers (11.2 vs 6.1 lb) and was slightly below maintenance. There were no differences (P > 0.05) in TT associated with this period of negative energy balance. Results indicate that pre-transit weaning, as a part of feedlot transition, did not add sufficient stress to alter TT compared to previously weaned calves.

Effects Of Sulfates In Water On Performance Of Steers Grazing Rangeland, Patricia S. Johnson, Hubert H. Patterson, Ronald Haigh
Effects Of Sulfates In Water On Performance Of Steers Grazing Rangeland, Patricia S. Johnson, Hubert H. Patterson, Ronald Haigh
South Dakota Beef Report, 2004
Surface and subsurface water in South Dakota often contains high concentrations of total dissolved solids (TDS) and sulfates, which, in severe cases, can cause livestock deaths. Data from our laboratory have demonstrated that sulfate concentrations of 3,000 ppm in water consumed by steers in dry-lot decreased ADG, feed intake, and water consumption. Little information is available on the effects of water sulfate concentrations on grazing livestock. This study evaluated the effects of water quality and two vegetation communities on the performance of steers grazing rangeland. Eight native pastures at the SDSU Cottonwood Research Station were used. Four pastures were dominated …
Effects Of Thiamin Supplementation On Performance And Health Of Growing Steers Consuming High Sulfate Water, Earl H. Ward, Hubert H. Patterson
Effects Of Thiamin Supplementation On Performance And Health Of Growing Steers Consuming High Sulfate Water, Earl H. Ward, Hubert H. Patterson
South Dakota Beef Report, 2004
Thiamin injections are often used to treat sulfate induced polioencephalomalacia (PEM) in beef cattle. It is unclear whether supplemental thiamin will reduce the incidence of PEM and improve performance in steers consuming water with elevated sulfate levels. This study was conducted to determine the effects of thiamin supplementation on performance and health of growing steers consuming water with high sulfate levels. Sixty-three steers (737 ± 2.97 lb) were stratified by weight and randomly allotted to one of nine pens. Pens were assigned to one of three treatments (3 pens/treatment) based on water sulfates and thiamin supplementation. Treatments were: 1) low …

Composition And Nutritive Value Of Corn Co-Products From Dry Milling Ethanol Plants, Simone M. Holt, Robbi H. Pritchard
Composition And Nutritive Value Of Corn Co-Products From Dry Milling Ethanol Plants, Simone M. Holt, Robbi H. Pritchard
South Dakota Beef Report, 2004
The South Dakota ethanol industry is rapidly expanding. As a direct result of this expansion it is expected that in excess of 500,000 tons of corn co-products will be available to livestock enterprises annually as a feed source. Processing methods are, in general terms, similar among dry milling ethanol plants. However, newer technology and small deviations of methods can alter the nutritive value of the co-products. Subsequently, diet formulations using general nutritive values may be inaccurate and cause production inefficiencies. The objective of this research project was to characterize the composition and nutritive value of corn co-products produced from several …

During 2002, the year with latest available USDA figures, livestock production in South Dakota represented 50.7% of total agricultural cash receipts, followed by 42.4% for crops and 6.9% for government payments. Dairy products, at $178,176,000, were fifth of all agricultural cash receipts and were a highly significant portion of the state’s economy. In light of possible dairy expansion in the …
Influence Of Diets Formulated To Increase The Supply Of Ketones Or Ketone Precursors On The Carbohydrate Status And Performance Of Transition Dairy Cows, Jeffrey Michael Defrain
Influence Of Diets Formulated To Increase The Supply Of Ketones Or Ketone Precursors On The Carbohydrate Status And Performance Of Transition Dairy Cows, Jeffrey Michael Defrain
Electronic Theses and Dissertations
Research to date has focused on increasing the supply of glucose precursors in transition dairy cows to reduce ketosis. Ketones and ketone bodies represent energy sources for body tissues; therefore, conserving blood glucose for lactose synthesis in the mammary gland. This led to the hypothesis that transition cows might benefit from diets formulated to stimulate rumen epithelial ketogenesis or dietary ingredients supplying ketone precursors. A series of experiments were conducted to study the impact of diets formulated to increase the supply of ketones (via feeding lactose, glycerol, or an alphaamylase enzyme preparation) or ketone precursors (feeding Ca soaps of longchain …

Effects Of Fasting And Transportation On Pork Quality Development And Extent Of Postmortem Metabolism, J.M. Leheska, D.M. Wulf, R.J. Maddock
Animal Science Faculty Publications
One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 × 2 × 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source was a significant source of variation (P < 0.05) for most composition and muscle quality variables. Fasting reduced hot carcass weight 3.6% (P < 0.05), but length of transport did not affect hot carcass weight (P > 0.05). There were no differences (P > 0.05) in percent lean among fasting and transport treatments. Fasted pigs had higher longissimus dorsi (LD) ultimate …

A Comparison Of Lifetime Implant Strategies For Beef Steers, Robbi H. Pritchard, Kelly W. Bruns, Donald L. Boggs
South Dakota Beef Report, 2003
Lifetime implant strategies were developed and applied to steer calves. The design was intended for evaluating strategies rather than specific implants. Strategies involving increasing potency of products used at common stages of production. Initial implants were administered when calves were approximately 2 mo of age. Implants did not increase BW at weaning or after backgrounding (P > 0.10) although they did increase ADG 5% over non-implanted controls during backgrounding (P < 0.05). The influence of implants on ADG was more pronounced during the finishing phase of production. Implants increased (P < 0.05) finishing phase ADG 18%, DMI 7.2%, and feed efficiency 9.4%. Overall post-weaning ADG increased 12% (P < 0.05) due to implants. Performance results changed when evaluating data on a live versus carcass weight basis due to differences in dressing percent. Increasing potency of the implant strategies caused progressive increases (P < 0.05) in carcass weight and ribeye area. Implanted steers produced fatter carcasses than did non-implanted steers (P < 0.05). There were no advances in skeletal or lean maturity attributable to the potency of the implant strategy. The frequency of carcasses grading Average Choice or better declined with implants. Implant strategies had no relevant influence on shear force. Overall, 12% of carcasses had a shear force > 5.0 kg (undesirable).

Characteristics Of Cressbred Progeny Of Holstein Dams Sired By Different Beef Breeds: A Review, Bruce C. Shanks
Characteristics Of Cressbred Progeny Of Holstein Dams Sired By Different Beef Breeds: A Review, Bruce C. Shanks
South Dakota Beef Report, 2003
Excellent reviews of cattle breed comparisons or breed-cross comparisons have been previously reported by Franke (1980), Long (1980), and Marshall (1994). However, these reviews do not contain information on the calving ease, performance, carcass characteristics, or beef palatability of crossbred progeny of Holstein dams sired by different beef breeds. In many countries dairy females are commonly mated to beef sires; however, in the United States the use of this practice is somewhat limited. Nevertheless, some United States dairy production schemes utilize beef sires on surplus Holstein heifers and cows. Also, some large commercial dairy operations purchase replacement heifers from outside …
