Reducing Feedlot Mud Problems, Steve Pohl

SDSU Extension Extra Archives

Muddy conditions decrease feed intake, slow aver¬age daily gain of cattle, increase problems with foot rot, and negatively affect feed efficiency. A feedlot with 4 to 8 inches of mud can decrease feed intake by 8 to 15%, slow daily gains by 14%, and reduce feed efficiency by 13%. Severe conditions, such as belly-deep mud, can reduce feed intake up to 30% and drop daily gain and reduce feed ef¬ficiency by up to 25%. These extreme wet conditions, however, do provide a benchmark to evaluate your present feedlot situation and to identify improvements that should be made. Recommended practices include …

Silage Gas Can Be Dangerous, Bob Durland

SDSU Extension Extra Archives

A danger associated with newly filled silos is due to accumulation of nitrogen dioxide. An individual may experience an immediate detrimental reaction to the presence of silo gas. Additionally, an individual may experience reactionary symptoms, sometimes called "Silo filler's disease", due to extended exposure to silage dust or gas.

Don’T Lose Scarce & Expensive Hay Through Storage Or Feeding, Bob Durland, Steve Pohl

SDSU Extension Extra Archives

Does it make sense to invest the time, labor and equipment in harvesting hay and then lose 30% of it during storage? With a 1l50 # round bale, worth $65/ton, this would amount to a loss of 345 # of hay, valued at $11.21, per bale. A producer who feeds his own hay is not only out the value of the damaged hay, but may have to purchase additional feed to replace that lost, doubling his expense.

Homeowner's Responsibilities For Using On-Site Sewage Treatment Systems, Russ Derickson

SDSU Extension Extra Archives

Do not generate more wastewater than the average daily flow (gallons per day) for which the on-site system was designed. Install a water meter to measure the volume of water being used by the household (or other facility) to determine the flow released into the on-site treatment system. If the system has a pump/lift station delivering septic tank effluent to the soil treatment unit, install an electrical event counter on each lift station. Install a water meter to measure water usage. The event counter will tally the number of pump operation cycles, which, if multiplied by the gallons pumped per …

Drinking Water Standards- Health Advisories Levels, Russ Derickson

SDSU Extension Extra Archives

Testing water is the first step in tackling domestic water quality problems. Water test reports will confirm your suspicion of quality problems. With results in hand you can determine the extent of the problem and the best alternative to solve it. A water test gives a quantifiable level of a contaminant at the time the sample was taken. These values usually are reported in mg/L (milligrams per liter).

Embryo Transfer In Beef Cattle, D. M. Marshall, J. A. Minyard

SDSU Extension Extra Archives

Embryo transfer allows one or more fertilized eggs (embryos) to be transferred from a donor female to other cows (recipients or surrogate mothers) for subsequent development and birth. Generally, the embryo transfer calf remains with its surrogate mother through weaning. Persons with adequate training and experience can perform embryo transfer with a reasonably high success rate. However, due to its relatively high cost, the use of embryo transfer to date has been limited mostly to increasing the reproductive rate of valuable cows from seedstock herds and to research applications. Most beef cows produce only one calf per year and fewer …

Heat Detection In Beef Cattle, Terry Goehring

SDSU Extension Extra Archives

New techniques and cheaper products for estrous synchronization of beef cattle have increased the use of this management practice for both commercial and seedstock producers. Hand-in-hand with synchronization comes the need to accurately detect heat in cows and heifers. Heat detection is simply looking for changes in a cow's behavior caused by her coming into, or being in, standing heat. The most definite behavioral change is standing firmly while mounted, with the mounting/riding process repeated several times.

Determining Pasture Rents, Martin Beutler

SDSU Extension Extra Archives

One of the more difficult decisions facing two parties in a pasture rental situation is determining the rent rate. Pasture rental charges often are based more on tradition than on a logical decision-making process. The rate must be deemed “fair” by both parties before a rental arrangement can be made. Several factors generally influence the rental value of pasture. Many of these factors are not directly related to the value of the available forage but to services and facilities which may or may not be present and/or provided by the landowner.

Feeding Kochia To South Dakota Livestock - Kochia Scopana —Fireweed, Burning Bush, Summer Cypress, Mexican Fireweed, Tumbleweed, And Dakota Alfalfa, John U. Thomson, Edward K. Twidwell, Regg D. Neiger

SDSU Extension Extra Archives

Kochia scoparia has been put up as hay for many years as an alternate feed for South Dakota livestock. Frequently, it is mixed with other hay or silage during winter feeding periods. The quality of kochia forage is extremely variable, however, and in certain situations kochia causes livestock poisoning. Many unknowns exist, so use caution when feeding this plant to livestock.

This case currently exists regarding the use of hormones, antibiotics and other feed additives in livestock production. The purpose of this fact sheet is to familiarize consumers with some of the products of technology that are currently utilized in the production of meat animals and to provide an evaluation of how these products impact the safety of meat and meat products.

Take An Accurate Forage Sample, Myers Owens, Nancy Thiex

SDSU Extension Extra Archives

Successful livestock production depends largely on the feeding program; and what you should feed depends on an accurate analysis of the forage portion of your ration. The accuracy of forage analysis depends on the sample that you send to the lab. Samples must be representative of the feeds being fed. Poor sampling will result in misleading values, higher feed costs, and reduced performance. In many feeding programs, the sample is the weak link. The results of the lab tests will be useful only if the sample accurately represents what your animals will be eating. Keep in mind that every field …

Using Frost-Damaged Soybeans In Livestock Rations, R. C. Thaler, J. E. Held, J. J. Wagner

SDSU Extension Extra Archives

Soybeans are routinely grown in the upper Midwest as a cash crop. However, late planting coupled with an early freeze can result in frost-damaged or “green beans.” Even after processing, the resulting soybean meal and soy oil are still green due to high chlorophyll concentrations. Since the consumer is reluctant to purchase green soy oil, frost-damaged soybeans (FDS) are of little use to the processing industry and often are docked at local elevators. However, when done properly, FDS can be marketed effectively through livestock. Frost-damaged soybeans, green beans, and immature soybeans are all synonymous terms and will be denoted by …

Forage Potential Of Cicer Milkvetch, Edward K. Twidwell, Kevin D. Kephart

SDSU Extension Extra Archives

Cicer milkvetch (Astragalus cicer L), a legume native from the Causcasus Mountains in Asia across southern Europe to Spain, was introduced into the United States in the 1920’s. It’s used for grazing, hay, and soil conservation in the northern and central Rocky Mountain Region of the United States and western Canada. Cicer milkvetch is gaining popularity in other regions of the United States because it is more tolerant than alfalfa to acidic or alkaline soils and does not cause bloat in grazing animals. Several South Dakota producers planted small acreages of cicer milkvetch in spring 1989. These acreages are being …

Forage Value Of Spring Oats And Triticale, Edward K. Twidwell, Nancy J. Thiex, Rober G. Hall

SDSU Extension Extra Archives

Spring oats commonly are grown in South Dakota for either grain or forage. The value of oats as forage depends on maturity when harvested and varietal characteristics. As oats matures, yield increases and quality decreases. Research indicates that tall, late-maturing varieties produce the highest forage yields. Triticale was originally developed as a grain for human and animal consumption, but it has the potential to be used as forage. Research suggests that spring triticale has forage yield and quality characteristics similar to oats and barley.

Profitability Determinants In South Dakota's Beef Cow/Calf Enterprise, Amy N. Singrey

Electronic Theses and Dissertations

South Dakota beef cow/calf producers who had completed a 2000 Standardized Performance Analysis were surveyed and interviewed to gain a better understanding of what personal characteristics and management factors may help determine profitability. Low, medium and high profitability categories were defined by calculating one standard deviation above or below a mean ROA. Producers were unaware of their profitability category at the time of the interview. Statistically significant differences were found in reference to the involvement of the operator in physical labor and management functions, and in the percentage of other family members involved in the management functions in the enterprise. …

Use Of High Pressure Liquid Chromatography To Detect And Quantify Oxytetracycline Marks In Walleye Otoliths And Dorsal Spines, Michael J. Hawkins

Electronic Theses and Dissertations

Oxytetracycline (OTC) is used to chemically mark calcified structures in walleye Stizostedion vitreum fry and fingerlings. Current visual methods for detection of these marks are subjective, and biologists are unable to quantify the amount of OTC in a sample. The goal of this study was to determine if high pressure liquid chromatography (HPLC) is a feasible and superior alternative for detecting and quantifying OTC in otoliths of fry-marked and spines of fingerlingmarked walleyes. Study objectives were to validate methodology of extraction of OTC from calcified tissue, detect and quantify extracted OTC using HPLC, and determine a cost comparison of current …

Evaluating The Point Of Separation, During Carcass Fabrication, Between The Beef Wholesale Rib And The Beef Wholesale Chuck, B.J. Reuter, D.M. Wulf, B.C. Shanks, R.J. Maddock

Animal Science Faculty Publications

This study determined whether there is a logical point of value change, related to either tenderness or consumer acceptance, at which to separate the beef carcass within the rib/chuck region. Rib/chuck rolls (RCR); (n = 30) consisting of the ribeye roll and chuck eye roll subprimals (2nd through 12th rib locations) were cut into 22 steaks each (two steaks per rib location), and Warner-Bratzler shear force and consumer purchase preference were evaluated for steaks at each rib location. Steaks from different locations of the RCR were composed of differing proportions of several muscles: longissimus muscle (LM), spinalis dorsi and multifidus …

Increasing Tenderness Of Beef Round And Sirloin Muscles Through Prerigor Skeletal Separations, B.C. Shanks, D.M. Wulf, B.J. Reuter, R.J. Maddock

Animal Science Faculty Publications

Crossbred steers (n = 30) were used to explore and compare tenderness improvements in beef round and sirloin muscles resulting from various methods of pre-rigor skeletal separations. Animals were slaughtered according to industry procedures, and at 60 min postmortem one of six treatments was applied to each side: A) control, B) saw pelvis at the sirloin round junction, C) separate the pelvic-femur joint, D) saw femur at mid-point, E) combination of B and C, and F) combination of B and D. After 48 h, the following muscles were excised from each side: semi-membranosus, biceps femoris, semi-tendinosus, and adductor from the …
