Influence Of Rapid Growth On Skeletal Adaptation To Exercise, Bonny Specker

Ethel Austin Martin Program Publications

During rapid growth, increased body weight and muscle strength result in increased loads on bone. Bone adapts to these increased strains by increasing bone modeling and remodeling. As the growth rate decreases, bone that was formed as a result of these adaptations continues to mineralize and "catch up", and bone modeling and remodeling decreases. Bone benefits of exercise in childhood are reported in some studies, although we observed less BMC gain at trabecular-rich sites during the peri-pubertal period in children who jumped than those who did not. Data from 13 existing pediatric exercise studies were compiled to determine whether similar …

Field Peas In Diets Fed To Swine, Hans H. Stein

SDSU Extension Special Series

Field peas (Pisum sativum L.) have a nutrient profile intermediate between corn and soybean meal. The digestibility of most nutrients in field peas is similar to that in soybean meal, and the concentration of digestible energy in field peas is similar to that in corn.
Although the digestibility of most nutrients may be improved by thermal treatment, field peas are usually fed to swine without prior heat treatment. Pigs tolerate field peas well and the palatability of diets containing field peas is not different from diets containing only corn and soybean meal.
Recent research with U.S.-grown field peas indicates that …

Public Price Reporting, Marketing Channel Selection And Price Discovery: The Perspective Of Cow/Calf Producers In The Dakotas, Scott Fausti, Bashir Qasmi, Doug Landblom, Martin Beutler, Pat Johnson, Roger Gates, Hubert Patterson, R. Salverson

Economics Staff Paper Series (1969 - 2017)

Cow/calf producers operating in the Dakotas were surveyed on their price discovery strategies, marketing channel preferences, and their perceptions of how regime change in the public price reporting system for fed cattle affected the beef industry in general and the cow/calf industry in particular. Survey results indicate cow/calf producers consider local institutions (auction barns etc.) to be more reliable for price discovery and marketing their feeder and stocker cattle than regional or national institutions (futures market etc.). Consistent with this view, producers perceive that the current public price reporting system is less reliable than local market sources when making individual …

North Central Water Quality Survey¹, Lanette Butler, Cody L. Wright

South Dakota Beef Report, 2006

This survey was conducted to determine the water quality in north central South Dakota. Twenty-one water sources from 16 different livestock operations were surveyed for this project. The water sources included five runoff-fed dugouts, 6 spring-fed dugouts, 4 deep wells (> 1000 ft), 3 medium-depth wells (100 to 500 ft) and 3 shallow wells (< 100 ft). Each water sample was initially tested with a hand-held Hanna Dist WP4 electroconductivity (EC) meter and the readings were recorded. Samples were then shipped to Servi-Tech Laboratories in Hastings, NE, where they were tested for EC, total dissolved solids (TDS), hardness, pH, calcium (Ca), chloride (Cl), magnesium (Mg), potassium (K), sulfate (SO4), sulfate-sulfur (SO4-S), and sodium (Na). Water quality indicators and mineral concentrations were not different over time when analyzed across all water sources or within each water source independently. Water from runoff-fed dugouts was lower (P < 0.05) in pH than water from spring-fed dugouts or wells. Well water contained greater (P < 0.05) concentrations of Cl than water from either runoff-fed or spring-fed dugouts. Potassium concentrations were greater (P < 0.05) in water from runoff-fed dugouts than in water from spring-fed dugouts or well water. Estimation of water quality without testing is highly inaccurate and variable. Livestock producers should obtain water samples for determination of water quality and adjust management to account for poor-quality water sources.

Rye And Turnips To Extend The Grazing Season For Weaned Calves, Alexander J. Smart, Richard J. Pruitt

South Dakota Beef Report, 2006

As part of a series of studies to determine the feasibility of short season crops to extend the grazing season for weaned calves, planting date studies and a grazing trial were conducted near Brookings, SD. Small plots of turnips were seeded with a no-till drill into oat stubble on Aug 1 and 15 in year 1. In year 2, rye and turnips were seeded on July 20, Aug 1, and Aug 15. Based on forage yield, planting these crops on or before August 1 in eastern South Dakota is recommended. In late September of year 3, 44 weaned heifers were …

Predicting Forage Production, Stocking Rate, And Beef Production In Eastern South Dakota: A Case Study, Alexander J. Smart, Eric Mousel

South Dakota Beef Report, 2006

In the summer of 1999, the Hand and Hyde County Bootstraps group met to form a working group to better understand “Management Intensive” Grazing (MIG) systems. From this working group of ranchers and state and federal agency personnel, evolved a goal to establish six demonstration sites in South Dakota (Figure 1). In 2000, the first demonstration site was established by Jim Faulstich near Highmore, SD in Hyde County. This site is a 320 acre pasture dominated by native mixed-grass prairie vegetation with some introduced species such as smooth bromegrass, Kentucky bluegrass, and crested wheatgrass. The pasture was fenced into 21 …

Effect Of An Injection Of Gnrh At Time Of Insemination Following Detection In Standing Estrus On Beef Cow And Heifer Pregnancy Rates, G. A. Perry

South Dakota Beef Report, 2006

An injection of GnRH at the initiation of standing estrus has been reported to increase pregnancy and circulating concentrations of progesterone in repeat breeder dairy cows, cows that have normal estrous cycles but will not conceive. The objective of this study was to determine the effect of administering an injection of GnRH at time of insemination on subsequent concentrations of progesterone and conception rates in beef cattle that have exhibited standing estrus. Eighty-two beef heifers at 2 locations were synchronized with the Select Synch-CIDR protocol (n = 42) or the 14-19 MGA protocol (n = 40) and AI was performed …

Effects Of Standing Estrus And Concentrations Of Estradiol On Uterine Ph¹, Josh R. Nelson, Bandi L. Perry, George A. Perry

South Dakota Beef Report, 2006

Research has demonstrated that cows that are in estrus within 24 h of fixed-time AI had elevated concentrations of estradiol and greater pregnancy rates compared to cows that are not in estrus. Our objective was to determine if estradiol and/or estrus had an effect on uterine pH during a fixed-time AI protocol. Non-lactating beef cows (n = 20) were treated with the CO-Synch protocol (100μg GnRH on d -9; 25 mg PG on d -2; and 100μg GnRH on d 0). Half (n = 10) the cows received an injection of estradiol cypionate (ECP; 1mg) 12 h following PG. Cows …

Association Of Microsatellite Markers On Bovine Chromosomes 5 And 6 With Carcass Traits, Angela M. Sanborn, Eduardo Casas, Artur J.M. Rosa

South Dakota Beef Report, 2006

The objective of this study was to identify chromosomal regions associated with phenotypic variation in carcass traits in three crossbred families. Three half-sib families were developed from crossbred sires. Families 1, 2, and 3 comprised 29, 25, and 77 offspring, respectively (n = 131). The genetic background of the sires, dams, and offspring was 1/3 Angus, 1/3 Hereford, 1/3 Simmental. Carcass traits collected were finished weight, hot carcass weight (HCW), marbling score, Quality Grade, Longissimus muscle area (LMA), rib fat, percent kidney pelvic, and heart fat (KPH), and Yield Grade. Microsatellite markers on chromosomes 5 and 6 were selected based …

Association Of Leptin Gene Markers With Carcass Traits In Beef Cattle, Angela M. Sanborn, Artur J.M. Rosa, Stacy J. Linblom, Anna R. Taylor

South Dakota Beef Report, 2006

The objective of this study was to evaluate four genetic markers on the leptin gene for association with carcass traits in three crossbred families. Three half-sib families were developed from crossbred sires. Families 1, 2, and 3 comprised 26, 21, and 66 offspring, respectively (n = 113). The genetic background of the sires, dams, and offspring was 1/3 Angus, 1/3 Hereford, 1/3 Simmental. Carcass traits collected were finished weight, hot carcass weight (HCW), marbling score, Quality Grade, Longissimus muscle area (LMA), rib fat, Yield Grade, and percent kidney, pelvic, and heart fat (KPH). The four markers analyzed were located on …

Cost Of Gain Comparison Between Cattle Finished At Opportunities Farm In South Dakota And Cattle Finished In Kansas, Erik Loe, Robbi Pritchard, Matt Loewe

South Dakota Beef Report, 2006

Cost of gain is an important factor in determining the profit or loss of feeder cattle. For comparison of cost of gain between cattle finished in Southeast South Dakota and cattle finished in Southwest Kansas closeouts of cattle fed at the Opportunities Farm near Lennox, SD were compared with information published by Kansas State University in the monthly Focus on Feedlots. Cattle feeders in the Midwest, including South Dakota, are competitive with cattle feeders in other regions of the United States due to this regions lower ration costs and cost of gain.

Effect Of Single Vs. Pulsing Doses Of Estradiol 17-Β And Trenbolone Acetate In Finishing Steers Fed A High Concentrate Diet, Sandi L. Parr, Robbi H. Pritchard, Kelly W. Bruns

South Dakota Beef Report, 2006

The effect of implant dosing pattern on anabolic response was evaluated in predominately Angus steers (n=192). Steers, except the control, were implanted with 1 of 3 different implant strategies. Cumulatively all implant treatments received a dose of 24 mg estradiol 17-β (E2) and 120 mg trenbolone acetate (TBA). Dosing patterns were 8 mg E2 and 40 mg TBA given 3 times; 12 mg E2 and 60 mg TBA given 2 times or 24 mg E2 and 120 mg TBA given 1 time. Implanted cattle had heavier body weights, increased average daily gain, and lower feed conversion compared to non-implanted controls. …

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) …

Effect Of Increasing Dietary Concentration Of Dried Distillers Grains Plus Solubles On Phosphorus Balance In Finishing Steers, Clint Benson, Cody Wright, Josh Mccarthick, Robbi Pritchard

South Dakota Beef Report, 2006

Eight crossbred steers (initial BW = 972.2 ± 33.5 lb) were used in a replicated Latin square design to determine the effect of increasing dietary concentrations of dried distillers grains plus solubles (DDGS) on phosphorus (P) balance in finishing steers. The control (CON) diet contained 79% dry rolled corn (DRC), 10% cottonseed hulls, 6% soybean meal (SBM), and 5% mineral supplement (total diet P concentration = 0.26%). In each of the remaining three diets, all of the SBM and a portion of the DRC were removed and replaced with DDGS at 12%, 24%, and 36% of the diet (total diet …

Cold Stress And Newborn Calves, Lanette Butler, Russ Daly, Cody Wright

SDSU Extension Extra Archives

Calf survival in northern climates can be a challenge. Death losses after birth may be due to one or more of several factors including infectious agents, dystocia, genetic abnormalities, and environmental stress.2 Cow nutrition also influences calf survivability2,3,7 as well as the timing and type of colostrum intake.8 These factors, whether singular events or in combination, dramatically impact calf survival.
