Heat Damage In Alfalfa Silage, Alvaro Garcia Jun 2005

Heat Damage In Alfalfa Silage, Alvaro Garcia

SDSU Extension Extra Archives

Differences in maturity of the stand, the weather, and harvesting, storing practices, and facilities affect the successful preservation of alfalfa silage. Silage fermentation is basically a destructive process, for nutrients are lost through chemical changes. The feeding value of alfalfa silage will always be less than that of the original forage, and the ensiling practices that are used will determine the extent of those losses. Losses from fresh forage to the ensiled feed arise from one or more of the following: field, oxidation, fermentation, and effluent. Aeration and the heating that results are among the most important causes.

Reducing The Risk Of Animal-To-Human Disease Transmission At Fairs, Achievement Days, And Petting Zoos, Russ Daly Jun 2005

Reducing The Risk Of Animal-To-Human Disease Transmission At Fairs, Achievement Days, And Petting Zoos, Russ Daly

SDSU Extension Extra Archives

Fairs and achievement days allow opportunities for those not involved with farming and ranching to gain a greater understanding of animal agriculture in our state. However, exposure to animals in public settings can pose a risk of zoonotic (or animal-to-human) diseases. In the past, a number of human disease outbreaks have been associated with visitors to animal exhibits. Enteric (intestinal) diseases are the most commonly reported health risks associated with animals in these settings. Other conditions such as ringworm, external and internal parasitisms, and other bacterial, viral, or fungal infections are also a source of concern. Injuries from kicks and …

Particle Size And Effective Fiber In Dairy Cow Diets, Alvaro Garcia, Kenneth Kalscheur Jun 2005

Particle Size And Effective Fiber In Dairy Cow Diets, Alvaro Garcia, Kenneth Kalscheur

SDSU Extension Extra Archives

Limited chewing takes place when a cow grazes or eats chopped forage, and a more thorough mastication will occur later when she “chews her cud.” Rumination, of which cud chewing is a part, is the process by which the contents of the rumen (the first chamber of the stomach) are thoroughly mixed and where the larger, less digested particles are redirected upward, to be regurgitated, chewed, and swallowed again. This process is repeated over and over until the feed particles attain a small enough size with relatively greater surface areas that enable bacteria and protozoa in the rumen to more …

Determination Of The Cyanide Metabolite 2-Aminothiazoline-4-Carboxylic Acid In Urine And Plasma By Gas Chromatography–Mass Spectrometry, Brian A. Logue, Nicholas P. Kirschten, Ilona Petrikovics, Matthew A, Moser, Gary A. Rockwood, Steven I. Baskin May 2005

Determination Of The Cyanide Metabolite 2-Aminothiazoline-4-Carboxylic Acid In Urine And Plasma By Gas Chromatography–Mass Spectrometry, Brian A. Logue, Nicholas P. Kirschten, Ilona Petrikovics, Matthew A, Moser, Gary A. Rockwood, Steven I. Baskin

Chemistry and Biochemistry Faculty Publications

The cyanide metabolite 2-aminothiazoline-4-carboxylic acid (ATCA) is a promising biomarker for cyanide exposure because of its stability and the limitations of direct determination of cyanide and more abundant cyanide metabolites. A simple, sensitive, and specific method based on derivatization and subsequent gas chromatography–mass spectrometry (GC–MS) analysis was developed for the identification and quantification of ATCA in synthetic urine and swine plasma. The urine and plasma samples were spiked with an internal standard (ATCA-d2), diluted, and acidified. The resulting solution was subjected to solid phase extraction on a mixed-mode cation exchange column. After elution and evaporation of the solvent, a silylating …

Confined Livestock Feeding Facilites: Control Of Stable Flies And Hosue Flies, Craig Anthony Apr 2005

Confined Livestock Feeding Facilites: Control Of Stable Flies And Hosue Flies, Craig Anthony

SDSU Extension Extra Archives

Stable flies and house flies are major pests near confined livestock facilities, cattle feedlots, and dairies, and cost livestock producers millions of dollars annually, especially in the more human environment of eastern South Dakota. Losses result from decreased weight gains and production by cattle that suffer the attack of the stable fly. Economic losses due to the house fly are much more difficult to determine, but nevertheless they are a nuisance to livestock and people. A problem is emerging with these two flies, especially the house fly. As urban development gradually spreads into what were traditionally agriculture production areas, the …

Drought And Stocking Rate Effects On Forage Yield From Western South Dakota Rangelands, Alexander J. Smart, Barry H. Dunn Apr 2005

Drought And Stocking Rate Effects On Forage Yield From Western South Dakota Rangelands, Alexander J. Smart, Barry H. Dunn

SDSU Extension Extra Archives

The vegetation of rangelands in a large portion of western South Dakota is an overstory of cool-season grasses such as western wheatgrass and green needlegrass and an understory of warm-season grasses such as blue grama and buffalograss (Fig 1). In semi-arid environments, precipitation is the main factor that determines forage production. Many western South Dakota counties receive less than 17 inches of annual rainfall, with 75% occurring between April and October. Pastures are usually managed as large units (more than 160 acres) because fencing and water developments are costly. Regrowth is usually limited to the spring, and 90% of forage …

Effect Of Ovulatory Follicle Size And Standing Estrus On Circulating Hormone Concentrations And Interval To Ovulation, George A. Perry Feb 2005

Effect Of Ovulatory Follicle Size And Standing Estrus On Circulating Hormone Concentrations And Interval To Ovulation, George A. Perry

South Dakota Beef Report, 2005

In postpartum cows, ovulatory follicle size at time of insemination (GnRH/TAI) influenced pregnancy rates following TAI, but had no effect on pregnancy rates when cows spontaneously ovulated. Furthermore, cows that exhibited estrus (± 24 h of GnRH/TAI) had higher pregnancy rates compared to cows not in estrus. The objective was to assess the relationship between ovulatory follicle size and estradiol concentrations, timing of the LH surge, timing of ovulation, and subsequent progesterone concentrations. Cows were synchronized with the CO-Synch (n = 64; induced ovulation) or the Select Synch (n = 20; spontaneous ovulation) protocol. Cows that exhibited estrus and were …

Effect Of Using Cidrs For Seven Days Before The Introduction Of Bulls On The Proportion Of Cows Conceiving Early In The Breeding Season, George A. Perry Jan 2005

Effect Of Using Cidrs For Seven Days Before The Introduction Of Bulls On The Proportion Of Cows Conceiving Early In The Breeding Season, George A. Perry

South Dakota Beef Report, 2005

Cows that conceive earlier in the breeding season wean calves that are older and heavier at weaning. Therefore, the objective of this study was to determine the ability of a CIDR to increase the proportion of cows that conceived early during a natural service breeding season. Two hundred twenty-two postpartum beef cows were allotted to one of two treatments: 1) cows were treated with a CIDR for 7 days before bulls were introduced (n = 100), 2) cows were not treated and served as a control (n = 122). Seven days before bulls were introduced to the herd CIDRs were …

Comparison Of The Efficiency And Accuracy Of Three Estrous Detection Methods To Indicate Ovulation In Beef Cattle, George A. Perry Jan 2005

Comparison Of The Efficiency And Accuracy Of Three Estrous Detection Methods To Indicate Ovulation In Beef Cattle, George A. Perry

South Dakota Beef Report, 2005

The ability to successfully artificially inseminate cattle requires determining the appropriate time to inseminate. Therefore, detection of standing estrus is a major factor in the success or failure of most artificial insemination programs. The objective of these experiments was to determine the efficiency and accuracy of three estrous detection methods (visual, penile deviated bull, and Estrus Alert estrous detection aids) to determine if animals were going to ovulate. Fifty-three postpartum beef cows were synchronized with an injection of gonadotropin releasing hormone (GnRH) followed by an injection of prostaglandin F2_ (PG) seven days later. Estrus was monitored for 72 hours following …

Spring Drought Effects On Rangeland Forage Yield From Clayey Ecological Sites In Western South Dakota, Alexander J. Smart, Roger N. Gates, Barry H. Dunn

South Dakota Beef Report, 2005

Understanding the historical influence of seasonal precipitation, especially spring precipitation, and stocking rate on forage yield would be desirable for planning purposes. The objectives of this study were to examine the historical precipitation pattern and how it influenced forage yield on pastures that were stocked at light, moderate, and heavy stocking rates for 15 years at the Cottonwood Range and Livestock Research Station in western South Dakota. Weather data from 1909 to 2004 at the station were analyzed to determine the frequency of occurrence of below (≤75 of mean), normal, and above normal (>125% of mean) spring precipitation (April, …

Sod Suppression Techniques For Legume Interseeding, Alexander J. Smart, Vance N. Owens, Dick Pruitt Jan 2005

Sod Suppression Techniques For Legume Interseeding, Alexander J. Smart, Vance N. Owens, Dick Pruitt

South Dakota Beef Report, 2005

Sod suppression is necessary for successful establishment of legumes interseeded into existing pasture; however such techniques vary in their effectiveness, cost, and management. Sod suppression experiments for legume interseeding into cool-season pasture were conducted at South Dakota State University’s Cow-Calf Unit located near Brookings, SD in 2003 to 2005. We evaluated (i) spring burn, (ii) field cultivator or disk, (iii) herbicide, (iv) heavy fall and spring graze, and (v) a control with no sod suppression. Legume species were alfalfa, birdsfoot trefoil, and kura clover. Sod suppression techniques enhanced the success of legume interseeding. In this study, the grazing equaled or …

Effect Of Grazing, Mowing, Or Herbicide On Leafy Spurge Control, Kelly W. Bruns, Alexander J. Smart Jan 2005

Effect Of Grazing, Mowing, Or Herbicide On Leafy Spurge Control, Kelly W. Bruns, Alexander J. Smart

South Dakota Beef Report, 2005

Leafy spurge (euphorbia esula L.) is an herbaceous perennial which is deep rooted and can reproduce by seeds and rhizomes. First introduced into North America in the 1800’s from Europe, it now covers 25 states in the USA and several provinces in Canada. It is a major concern in North Dakota, South Dakota, Wyoming, Montana, and Nebraska. Leafy spurge is considered a noxious weed that is extremely competitive, establishing itself in pastureland and roadsides. Bangsund et al. (1997) estimated that by 2005, uncontrolled leafy spurge acres would reach 18.5 million in the Northern Great Plains. The cost of leafy spurge …

Relative Efficiency Of Natural Feeding Programs Using Germ Or Bran Cake From A Dry Milling Process, Robbi H. Pritchard, Donald L. Boggs Jan 2005

Relative Efficiency Of Natural Feeding Programs Using Germ Or Bran Cake From A Dry Milling Process, Robbi H. Pritchard, Donald L. Boggs

South Dakota Beef Report, 2005

This experiment was designed to evaluate the potential of using high-fat ethanol co-products in cattle feeding programs that exclude implants and ionophores. Four treatments included: 1) Positive Control, implanted steers fed a typical diet that included 29g/T monensin; 2) Control Diet fed to non-implanted steers; 3) 14% Germ, no implant or ionophore; and 4) 30% Bran Cake, no implant, no ionophore. After a 110 d finishing period, the breakeven (B/E) fed cattle price increased $3.04/cwt when an implant was not used on the Control diet. The Germ diet resulted in comparable performance as the Control diet fed to non-implanted steers. …

Composition And Nutritive Value Of Corn Fractions And Ethanol Co-Products Resulting From A New Dry-Milling Process, Greg B. Kleinhans, Robbi H. Pritchard, Simone M. Holt Jan 2005

Composition And Nutritive Value Of Corn Fractions And Ethanol Co-Products Resulting From A New Dry-Milling Process, Greg B. Kleinhans, Robbi H. Pritchard, Simone M. Holt

South Dakota Beef Report, 2005

The development of a new dry-milling process for the production of corn ethanol has resulted in new feedstuffs. This process fractionates the corn kernel prior to fermentation. Pre-fermentation fractions include bran, germ, and endosperm. Post-fermentation fractions include dried distillers grains (DDG) and condensed distiller solubles (syrup). Proximate analysis was conducted on these fractions along with the parent corn sample. Equations were used to predict TDN and undegradable intake protein (UIP). These feeds differ substantially from historical dried distiller’s grains with solubles (DDGS). Feeding experiments will be necessary to confirm the results of the predicted feed values.
