Feasibility Exploration: "Perfectly" Integrated Crop-Livestock Production, Donald Taylor, Diane H. Rickerl
Economics Research Reports
In this research report, the following question is examined. Can individual integrated crop and cow-calf operations be simultaneously "balanced" from the standpoints of (1) amounts of manure produced "matching" (plus or minus 10%) the soil fertility needs of producers' cropland and rangeland and (2) amounts of feedgrains and roughages produced matching (plus or minus 10%) the nutrient needs of producers' livestock? Answers to the question were sought through examination of livestock manure production and utilization and livestock feedstuff production and consumption on eight South Dakota integrated crop-livestock case farms.

Assessment Of Failure Of Colostral Absorption Among Well-Managed Herds Using A Simple Screening Test, Bill Epperson, Dick Pruitt, Con Marshall, Anna Drew
Assessment Of Failure Of Colostral Absorption Among Well-Managed Herds Using A Simple Screening Test, Bill Epperson, Dick Pruitt, Con Marshall, Anna Drew
South Dakota Beef Report, 1996
Failure of calves to ingest colostrum early in life is associated with an increased risk of illness and death. Colostral antibody absorption can be easily estimated with a blood sample collected after the calf is 24 hours old. This study was conducted to determine the proportion of calves born at the four SDSU beef units that were affected with inadequate passive transfer (IPT) as a result of inadequate colostral antibody absorption. Of the 333 calves, 44 were affected with IPT (1 3.2%). There were significant differences in IPT between units, suggesting that environmental factors unique to each unit may have …
Kappe_Casein And Beta-Lactoglobulin Genotype Effects On Milk Production And Maternal Calf Growth Traits In Crossbred Beef Cattle, D. A. Henderson, D. M. Marshall
Kappe_Casein And Beta-Lactoglobulin Genotype Effects On Milk Production And Maternal Calf Growth Traits In Crossbred Beef Cattle, D. A. Henderson, D. M. Marshall
South Dakota Beef Report, 1996
Cows were genotyped at the kappa-casein and beta-lactoglobulin loci and evaluated for milk yield, calf birth weight, weaning weight, and average daily gain from birth to 109 days and from birth to 21 1 days of age. The interaction of breed-group with genotype was significant for milk yield at both loci. Cow genotype and additive allelic effects were significant or approached significance for both measures of calf average daily gain and weaning weight at the kappa-casein locus. Cow genotype and additive allelic effects were significant for calf average daily gain to 109 days at the beta-lactoglobulin locus. Cow genotype approached …
Effect Of Feed Delivery Management On Yearling Steer Performance, S. J. Bierman, R. H. Pritchard
Effect Of Feed Delivery Management On Yearling Steer Performance, S. J. Bierman, R. H. Pritchard
South Dakota Beef Report, 1996
Gain efficiency by cattle fed high grain diets can be affected by feed delivery management (FDM). Restricted or limit feeding improves feed efficiency but can reduce ADG. This experiment was designed to evaluate if feeding near ad libitum intake while reducing the amount of variation between daily feed deliveries could provide feed efficiency advantages over unrestricted access to feed without restricting ADG. The FDM strategies for the 121-day feeding period included prescription intakes (PI) where variability between day to day feed deliveries were minimized or ad libitum intake (ALI) where feed was always available. Crossbred yearling steers (n = 76, …
Inophore Programs For Finishing Yearling Steers, R. H. Pritchard
Inophore Programs For Finishing Yearling Steers, R. H. Pritchard
South Dakota Beef Report, 1996
The relative effectiveness of three ionophore feeding strategies was compared in yearling steers. Six pens of 8 steers were assigned to each of the following treatments: A) no ionophore fed, B) lasalocid (33 glT) fed for 28 days and then replaced with laidlomycin propionate (1 1 g/T) for the balance of time on feed; C) monensin (28 g/T) fed throughout, and D) laidlomycin propionate (11 g/T) fed throughout. A five diet step-up program was used that culminated in a final diet based on cracked and high moisture corn and 7% ground hay. lonophores increased (P< .05) ADG (3.9%) and carcass weight and lowered (P<.05) feed/gain 4.5% during the 135-day feeding period. Among ionophore treatments, monensin resulted in a lower (P< .05) cumulative ADG and carcass weight than diets containing laidlomycin propionate. Three of the four steers removed from the trial due to metabolic disorders were from the no ionophore treatment.
Effect Of Increasing Levels Of Condensed Corn Distillers Solubles On Performance Of Finishing Steers, G. A. Sharp, C. P. Birkelo
Effect Of Increasing Levels Of Condensed Corn Distillers Solubles On Performance Of Finishing Steers, G. A. Sharp, C. P. Birkelo
South Dakota Beef Report, 1996
A trial was conducted as a randomized block design to assess the effects of condensed corn distillers solubles (CCDS) on performance and carcass merit of yearling steers (n = 21 6) fed 90% concentrate finishing diets. CCDS was included at 0 (MSBM), 5 (5CCDS1, 10 (IOCCDS), or 20% (20CCDS) of diet DM, replacing soybean meal, molasses, and corn. Average daily gain increased (PC .051 for steers fed CCDS but, along with a numerical trend (P= .14) of increasing DMI, resulted in no improvement in FIG (P>.20). Steers were harvested on day 108. Carcass weight and dressing percent for steers …

Effect Of Increasing Levels Of Condensed Corn Distillers Solubles On Performance Of Growing Steers, G. A. Sharp, C. P. Birkelo
South Dakota Beef Report, 1996
A trial was conducted as a randomized block design to assess the effects of condensed corn distillers solubles (CCDS) on performance of steer calves (n = 200) fed 40% concentrate, dry rolled corn-hay based growing diets. CCDS was included at 0 (MSBM), 5 (5CCDS1, 10 (IOCCDS), or 20% (20CCDS) of diet DM, replacing soybean meal, molasses, and corn. A corn silagetsupplement diet was also included (SIL). Dry matter intakes at higher CCDS levels were lower than that of MSBM (P<.05). Average daily gain was not affected (P>.20) and, as a result, feed efficiency (FIG) tended to improve (P = .14). Steers fed SIL consumed less DM …

Effects Of Mga On Prepubertal Beef Heifers, L. M. Butler, H. L. Miller, D. D. Zalesky, D. M. Marshall, K. Vanderwal, C. Moret
South Dakota Beef Report, 1996
A 2-year study (1 995 and 1996) utilized prepubertal beef heifers to study the effects of feeding MGA to induce puberty. Heifers were allotted to two groups, control or treatment, based on breed, age and weight. Treatment heifers received MGA for 14 days at a rate of .4 mglday with their diet, while control heifers received the same diet free of MGA. In year 1 (n = 55; control = 28, treatment = 27), heifers averaged 627.7 Ib and were 301.9 days of age at the start of the treatment. There was no difference in age at puberty (P=.65) with …

Long-Term Protection From Bovine Viral Diarrhea Virus In Feedlot Cattle, C. C.L. Chase, J. Hanson, R. Fraser, L. Braun, S. Anderson, D.J. Hurley
South Dakota Beef Report, 1996
Bovine viral diarrhea virus (BVDV) causes respiratory and reproductive disease. The duration of immunity of an inactivated vaccine (Virashield 5: Grand Laboratories, Freeman, SD) was measured in two challenge studies. In both studies the vaccinated animals demonstrated fewer clinical signs when challenged with Type II BVDV at 11 or 13 months post vaccination. These results indicate that an inactivated vaccine administered properly can protect animals against disease up to at least a year post vaccination.

Pathogenesis Of Bovine Herpesviruses In Vitro, C. C.L. Chase, S. Stone, K. Bialas, C. Carlson, W. Wiese, L. Braun
South Dakota Beef Report, 1996
Bovine herpesviruses cause acute disease in cattle. Bovine herpesvirus 1 (BHV-1 or IBR) is a respiratory virus, while bovine herpesvirus 5 (BHV-5) affects the brain and causes a viral encephalitis. Studies in the laboratory showed no difference in the growth rate of BHV-1 or BHV-5 in blood vessel, brain, or kidney cells. The ability of BHV-1 to cause cells to die is not caused by apoptosis (programmed cell death). Further studies on the pathogenesis of bovine herpesviruses need to be conducted to improve control and prevention measures.
