An Analysis Of Selected Policy Alternative For 1990 Farm Bill On South Dakota's Agriculture Sector, Bashir Qasmi Dec 1990

An Analysis Of Selected Policy Alternative For 1990 Farm Bill On South Dakota's Agriculture Sector, Bashir Qasmi

Economics Research Reports

As the congressional debate for the finalization of 1990 Farm Bill nears, the interest in analysis of the new farm bill is increasing. The continued large federal budget deficits, the GATT negotiations, and the increased momentum of conservation and environmental issues are all expected to exert influence in shaping the 1990 farm bill outcome. Practical options for a 1990 farm bill and its impacts for U.S. agriculture are discussed in Schnittker (1990), Westhoff, et al. (1990a), Westhoff, et al. (1990b) and Meyer (1990). These papers, however, analyze the impacts on a national level. With a recent trend of reducing government …

For Yield Test Weight Disease Resistance: Settler Oat, Robert G. Hall, Dale L. Reeves, J.J. Bonneman Jul 1990

For Yield Test Weight Disease Resistance: Settler Oat, Robert G. Hall, Dale L. Reeves, J.J. Bonneman

Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)

'Settler,' a new spring oat, was released by the South Dakota Agricultural Experiment Station in 1989 during South Dakota's Centennial celebration and named in honor of the pioneers that settled in South Dakota. Settler exhibits a significant improvement over other varieties released by Reeves in its tolerance to barley yellow dwarf (BYD) virus. This disease is caused by a virus transmitted by insects and is commonly called "red leaf."

A Five-Year Case History Of Retained Ownership, D.M. Marshall, J.J. Wagner Jan 1990

A Five-Year Case History Of Retained Ownership, D.M. Marshall, J.J. Wagner

South Dakota Beef Report, 1990

A case history of retaining ownership of steer calves from weaning through slaughter was examined for calves born in 1985 through 1989. Calves were reared to weaning at the SDSU Antelope Range Livestock Station and following weaning were managed under a custom feedlot arrangement. Retaining ownership from weaning through slaughter resulted in profits of $1.83, $215.41, $162.75, $78.58 and $80.65 (excluding interest on calf) for the 1985 through 1989 calf crops, respectively. Cattle prices, feed costs and postweaning profitability tended to vary over years considerably more than cattle performance.


The Economics Of Placing Heavy Steers Back In The Feedlot, C.M. Pankonin, R.H. Pritchard Jan 1990

The Economics Of Placing Heavy Steers Back In The Feedlot, C.M. Pankonin, R.H. Pritchard

South Dakota Beef Report, 1990

In the fall of 1989, 30 fed steers (1,069 Ib) marketed through the Sioux Falls Stockyards were purchased by a feeder to go back on feed rather than to slaughter. The cattle were purchased for $70/cwt on a $63/cwt fed steer market. These steers were previously on trial at the SDSU research feedlot. Thirty-two contemporary steers were retained at SDSU for determining subsequent costs of production and economic risks of placing heavy cattle on feed. The fed steer and futures markets were tracked for the next 27 days. During this period, there was no potential for profit based on break …

Feed Utilization By Steers With Chronic Cryptosporidia Infection, R.H. Pritchard, J.U. Thomson, C.D. Mullaney

South Dakota Beef Report, 1990

The effect of chronic cryptosporidia infection on feed utilization by yearling steers was evaluated. Two control and two infected steers were fed a corn silage based diet. lnfected steers had shown evidence of cryptosporidia infection over a 6-month period prior to determining feed digestibility. Digestibilities of dry matter (58.1 vs 54.0 ± 3.9%), NDF (51.7 vs 54.6 ± 2.5%), ADF (35.8 34.8 ± 7.1%) and crude protein (45.0 vs 45.9 ± 5.3%) were unaffected (P>.10) by parasite infection for control and infected steers, respectively.


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 Jan 1990

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 …


Effects Of Estradiol-Trenbalone Acetate Implant Combinations On Feedlot Performance And Carcass Traits Of Two Steer Types, R.H. Pritchard, D.H. Gee, M.A. Robbins Jan 1990

Effects Of Estradiol-Trenbalone Acetate Implant Combinations On Feedlot Performance And Carcass Traits Of Two Steer Types, R.H. Pritchard, D.H. Gee, M.A. Robbins

South Dakota Beef Report, 1990

Hereford x Angus (HA) and predominantly Gelbvieh cross (Gx) steer calves either received no implant (control) or were implanted initially and again at 77 days on feed with a combination of estradiol and trenbalone acetate based implants. Calves were started on feed in December weighing 677 Ib and fed for 146 to 167 days. Fed for a common period of time, implanting steers increased (Pc.05) ADG, dry matter intake, final weight, carcass weight, rib fat thickness and yield grade. Implanting reduced (Pc.01) marbling scores. Gx steers were heavier and grew more rapidly than HA steers. There were no interactions between …

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 Jan 1990

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 …
