Combinations Of Synovex And Finaplex For Yearling Steers, J.J. Wagner, R.H. Pritchard, J.U. Thomson, M.J. Goetz

South Dakota Beef Report, 1990

One hundred twenty-three yearling black baldy steers were fed in one pen for 123 days at a commercial feedlot near Kimball, South Dakota. On day 1 in the feedlot, 53 steers were implanted with Synovex-S, 53 steers were implanted with the combination of Synovex-S and Finaplix-S and 17 steers received no implant. On day 60 in the feedlot, 18 of the Synovex-S steers and 18 of the combination steers were reimplanted using Synovex-S. Also on day 60, 18 of the Synovex-S steers and 18 of the combination steers were reimplanted using the combination of Synovex-S and Finaplix-S. The remaining steers …

Interrelationships Of Heifer Milk Production And Other Biological Traits With Production Efficiency To Weaning, B.A. Freking, D.M. Marshall

South Dakota Beef Report, 1990

Interrelationships among milk production, cow-calf feed efficiency and other biological traits were evaluated on first-calf females and their calves. Production efficiency was defined as cumulative feed metabolizable energy consumed by the dam-calf pair during the year divided by calf weaning weight. Results indicated that increased levels of milk production were associated with improved production efficiency to weaning as long as calves have the genetic potential to convert the extra milk into body weight gains. However, the incremental improvement in efficiency per unit of increased milk was less for each additional unit of milk.

Whole Plant Faba Bean Siage As A Component Of Growing Steer Diets, J.J. Wagner, H. Nantoume, R. Hanson, D.R. Sorenson

South Dakota Beef Report, 1990

Whole plant faba bean silage was compared to corn-alfalfa silage as a roughage source in 30% roughage growing steer diets. When the proportion of faba bean silage was increased from 0 to 10, 20 and 30%, respectively, daily feed intake, average daily gain and feed conversion of the steers were 18.32, 18.38, 18.23, 19.13 Ib per head; 3.66, 3.42, 3.39, 3.57 Ib per head; and 5.01, 5.38, 5.37 and 5.36, respectively. Substitution of faba bean silage for corn-alfalfa silage in a 30% forage diet had no significant (Pc.05) effect on feed intake, weight gain and feed efficiency for growing steers.

Hydrolyzed Feather Meal Supplementation For Lactating Range Cows, P.A. Momont, R.J. Pruitt, T. Weber

South Dakota Beef Report, 1990

A 2-year study involving 178 cow/calf pairs was conducted to evaluate hydrolyzed feather meal4 as a protein supplement for cows grazing native range during early lactation. Calving season occurred from mid-March until late April. Within a week after calving, cows were fed either a soybean meal or feather meal-corn supplement that provided approximately .83 1b crude protein per cow daily. Cow weight and condition score changes from calving until early May and percentage of cows cycling early in the breeding season (early June) were similar between supplement groups. Calf average daily gains from birth until May were not affected by …

Evaluation Of Controlled Release Chromic Oxide Boluses And Alkaline Hydrogen Peroxide Lignin As Markers To Determine Intake Of Cows Fed Mature Prairie Hay, P.A. Momont, R.J. Pruitt, R.J. Emerick, R.H. Pritchard

South Dakota Beef Report, 1990

A digestion trial involving 8 mature cows fed mature prairie hay ad libitum was conducted to determine the validity of controlled release chromic oxide (Cr) and alkaline hydrogen peroxide lignin (APL) as markers for prediction of forage intake by the fecal output (F0)/indigestibility ratio technique. Seven days after oral administration of Cr boluses, total FO was collected daily, weighed and sampled. Rectal fecal grab samples were collected at 10:00 a.m. each day and at 4-hour intervals on day 4 of collections. Mean fecal Cr output based on total fecal collections was 1,662 mg Cr/day compared to a manufacturer's suggested value …

Alternate Day Supplementation Of Corn Stalk Diets For Ruminants With High Or Low Ruminal Escape Protein Supplements, R.M. Collins, R.H. Pritchard

South Dakota Beef Report, 1990

Two experiments were conducted to determine the effects of feeding soybean meal (SBM) and corn gluten meal (CGM) based, isonitrogenous supplements at 24- or 48-hour intervals on corn stalk utilization. Exp. 1. Yearling rams were fed either protein supplement as 100 g daily or 200 g on alternate days. DM1 was lower (Pc.10) for the CGM than SBM based supplements. Protein source and interval of feeding did not affect (P>.10) digestible dry matter intake (DDMI) or disappearance of dry matter (DMD), but an interaction was observed (P<.05) between protein source and interval of feeding. Nitrogen retention was greater for CGM (P<.10) and 48-hour supplementation (P<.01). However, an interaction between protein source and interval of feeding occurred (P<.10) for N retention. Exp. 2. Angus and Hereford x Anugs steers (119 head; 620 ± 1.9 Ib) allotted to 8-head pens were fed similar diets except supplements (46% crude protein) also provided 0 (OM) or 200 (200M) mg per head per day monensin. CGM supported higher (Pc.05) ADG and gain/feed (G/F) than SBM, but a protein by monensin interaction occurred (Pc.10) for ADG and GIF. There was an interval by monensin interaction for ADG (P<.10) and DM1 (P<.05). An interaction between protein and interval occurred for plasma urea N on day 1 (P<.01) and day 2 (P<.10) of the sampling period. CGM was an effective isonitrogenous substitute for SBM based supplements in these applications. Supplementation at 48-hour intervals supported higher N utilization. High intermittent dosages of monensin appeared detrimental to calf performance.

Use Of Sunflower Hulls As The Roughage Component Of Finishing Diets For Yearling Steers, R.H. Pritchard, M.A. Robbins

South Dakota Beef Report, 1990

Sunflower hulls were substituted for grass-alfalfa hay as the roughage component of finishing diets for yearling steers. Feed intake was lower when sunflower hulls were fed, resulting in reduced rate of gain and increased feed conversion. When diets were formulated to contain 12% NDF rather than 10% roughage, performance of steers fed either roughage source was similar. Sunflower hulls because of low cost can be used in finishing diets at 5% of dry matter intake without affecting production costs. Feeding higher levels of unprocessed sunflower hulls is discouraged.

Anhydrous Ammonia Or Liquid Supplement Treatment Of Wheat Straw: Demonstration Results, T.B. Goehring, R.H. Pritchard, T. Derr, J. Thelen

South Dakota Beef Report, 1990

The effect of anhydrous ammonia or liquid supplement treatment of wheat straw was evaluated by field demonstration in response to the drought of 1989. Ammoniation of wheat straw increased estimated TDN content by 7.8 percentage points and crude protein by 7 percentage points in comparison with untreated straw. Adding a liquid protein supplement to wheat straw increased estimated TDN content by 1.5 percentage points and crude protein by .6 percentage points. Ammoniation increased the quality of wheat straw to a level comparable to prairie hay. Based on nutrient analysis, the ammoniation procedure was more effective in improving the quality of …

Response Of Yearling Cattle To Limit Fed Finishing Diets In Different Seasonal Environments, C.P. Birkelo, D.R. Sorenson

South Dakota Beef Report, 1990

Two trials were conducted to evaluate limit-feeding of finishing diets to yearling steers in different seasonal environments. In Trial 1, 72 yearling steers were fed (I) ad libitum or (2) 93% of ad libitum (restricted) from July through early November. Trial 2 was conducted from January through early May with a similar group of steers. Weather data collected at the feedlot indicated that the weather during Trial 1 was similar to the 30-year average (Trial 1 average air temperature = 62 OF), but the weather during Trial 2 was 10°F warmer than typical (average air temperature = 37 OF). In …

The Economic Value Of Grazing Public Lands In Western South Dakota, Martin Beutler

Economics Staff Paper Series (1969 - 2017)

South Dakota has relatively few acres of public rangeland when compared to other western states. However, public grazing in South Dakota can have a major impact on local area economies in which public grazing occurs. Total harvested AUMs have declined over the study period. The total value of public land grazing has climbed mainly due to higher cattle prices. In 1988, South Dakota public lands participated in the production of approximately $35 million in gross livestock production. This gross production generated an estimated $66 million in economic activity to the region. In 1988, public lands accounted for an estimated $22.8 …

Planning For Tomorrow-Today: A Financial Management Program For South Dakota Agricultural Producers, 1985- 1988, Burton Pflueger

Economics Staff Paper Series (1969 - 2017)

As conditions in the ag economy worsened the early 1980s, it became apparent that m any farmers and ranchers were crisis managing their operations. They responded to situations as they developed, instead of anticipating changes and preparing ways to cope. The South Dakota Cooperative Extension Service (SDCES) realized crisis-managing would be disastrous for many producers and recognized a need for educational programs to help producers manage the crisis. The Planning For Tomorrow Today (PTT) program was developed by the SDCES to meet this need. PTT was designed to be used by any producer, whether he was experiencing financial difficulties or …

Management Practices Of Successful Family Farms, Burton Pflueger, Rebecca Lafferty

Economics Staff Paper Series (1969 - 2017)

"Success" has constantly been a difficult word to define both for family-farm managers as well for those individuals who work closely with them . Past research in successful farm management have tried to measure success through a wide variety of factors: profitability, achieving personal goals, farm survival, farm growth, and financial measures of success such as accumulated wealth or annual profitability. More recently, a successful farm operator could also be classified as successful if he was able to achieve the objectives or goals set forth for his operation. Therein lies the conflict. If a farm operators goals for successful management …

Price Variability At South Dakota Livestock Auction Markets, Larry Janssen, Richard Shane

Economics Research Reports (1969 - 2017)

Livestock prices are established through various market channels, such as terminal markets and auction markets. Auction sales account for 74% of all cattle purchases and 64% of all cattle sales by South Dakota producers (Clauson, 1983). Livestock auctions are also an important market channel for feeder pigs, slaughter hogs and slaughter lambs. The major purpose of this research was to determine which factors, controllable or noncontrollable, have a significant impact on livestock prices established at auction market outlets in South Dakota. Factors to be tested include market location, month of sale, sex, weight, breed and lot size. Data on sale …
