Nitrate Poisoning Of Livestock Causes And Prevention, Lester R. Vough, E. Kim Cassel, Scott M. Barao Jan 2006

Nitrate Poisoning Of Livestock Causes And Prevention, Lester R. Vough, E. Kim Cassel, Scott M. Barao

SDSU Extension Extra Archives

Nitrate poisoning is generally caused when animals eat too much forage that is high in nitrates not changed to protein in the plant. Poisoning can also happen when animals eat too much urea or nitrogen fertilizer spilled in the field or left where the animals can find it. Nitrate fertilizer is palatable, especially to cattle.

Prussic Acid Poisoning Of Livestock: Causes And Prevention, Lester R. Vough, E. Kim Cassel Jan 2006

Prussic Acid Poisoning Of Livestock: Causes And Prevention, Lester R. Vough, E. Kim Cassel

SDSU Extension Extra Archives

What Is Prussic Acid? Sudangrass, sorghum, and sorghum-sudangrass hybrids are among a group of plants that produce cyanide, which can poison livestock under certain conditions. Also included in this group of plants are johnsongrass, chokecherry, and black cherry. These plants produce cyanogenic glycosides during their growing stage. Glycosides are compounds containing a carbohydrate (sugar) and a noncarbohydrate residue in the same molecule. They decompose (breakdown) into glucose sugar and noncarbohydrate residue by hydrolysis (addition of water) as a result of enzymatic action. In cyanogenic plants this decomposition frees the cyanide from its chemical bond, and it becomes toxic hydrocyanic acid, …

Alternative Forages For Dairy Cattle: Soybeans And Sunflowers, Alvaro Garcia Jan 2006

Alternative Forages For Dairy Cattle: Soybeans And Sunflowers, Alvaro Garcia

SDSU Extension Extra Archives

Oilseed crops such as soybeans and sunflowers may be harvested for forage when you have decided that dry conditions have shrunk their oilseed yield below your economic threshold for seed harvest or when you face a shortage of roughage. These alternative forages can help stretch your usual forages, whose yield most likely is also compromised under dry conditions. How you will harvest alternative crops for forage depends on the individual crop and its stage of maturity.

Dealing With Heat Stress In Dairy Cows, Alvaro Garcia

SDSU Extension Extra Archives

Alleviating heat stress is critical to milk production. Heat stress from high environmental temperatures can be compounded by mistakes in managing and feeding the cows. Water is your first concern during periods of high temperatures. Water physical properties—heat conductivity and latent heat of vaporization—help transfer heat from the body of the animal to the environment.

Short On Feed? Should You … Move The Feed To The Livestock, Or The Livestock To The Feed?, Martin K. Beutler

SDSU Extension Extra Archives

With drought severely curtailing pasture and hay production over much of South Dakota, many ranchers are faced with either buying feed or moving their livestock to feed if they want to retain ownership of their animals. Which alternative to choose depends on the economics of the alternatives. This Extension Extra provides a worksheet for you to evaluate your particular situation. The first step is to determine the cost of putting purchased feed in the feedbunk. This is the sum of the (1) purchase cost of the feed, (2) shipping costs, (3) opportunity cost of labor in feeding and caring for …

El Daño Térmico En El Ensilaje De Alfalfa, Alvaro Garcia Jan 2006

El Daño Térmico En El Ensilaje De Alfalfa, Alvaro Garcia

SDSU Extension Extra Archives

La diferencia en la maduración del cultivo, el clima, las prácticas de cosecha, el almacenaje y las instalaciones, son factores que afectan la preservación exitosa del ensilaje de alfalfa. El ensilaje es en esencia un proceso destructivo ya que se pierden nutrientes a través de cambios químicos. El valor alimenticio del ensilaje de alfalfa siempre va a ser inferior que el del forraje original y las prácticas de manejo que se utilicen van a determinar la extensión de esas pérdidas. Las pérdidas del forraje fresco al alimento ensilado se originan a partir de una o más de las siguientes: de …

Tamaño De Partícula Y Fibra Efectiva En La Dieta De Las Vacas Lecheras, Alvaro Garcia, Kenneth Kalscheur

SDSU Extension Extra Archives

Cuando la vaca pastorea o ingiere forraje picado la masticación inicial es limitada completándose más tarde durante el período de la rumia. La rumia es el proceso por el cual los contenidos del rumen son completamente mezclados y adónde las partículas más grandes y menos digeridas son re-dirigidas hacia arriba, regurgitadas, masticadas y tragadas nuevamente. Este proceso se repite una y otra vez hasta que las partículas alcanzan un tamaño lo suficientemente pequeño y un área de superficie relativamente grande que permite a las bacterias y protozoarios del rumen digerirlas más eficientemente. Llegado el momento las partículas de alimento abandonan …

Molecular And Biochemical Changes In The Ileum Of Weanling Pigs Fed Antibiotics As Growth Promotant And In Germ-Free Conditions, Sajan George Jan 2006

Molecular And Biochemical Changes In The Ileum Of Weanling Pigs Fed Antibiotics As Growth Promotant And In Germ-Free Conditions, Sajan George

Electronic Theses and Dissertations

Antibiotics are routinely fed as growth promoters to weanling pigs for the past 50 years. However, frequent use of feed antibiotics potentially results in emergence of drug resistance in microbes, which could be transferred to human pathogens and would interfere with the effective use of therapeutic antimicrobials in human medicine. Such health concerns about the use of antibiotics in animal feeds have led to considerable scientific research and debates. Recently, use of antibiotics in animal feeds has been banned in the European Union and would possibly impact US agriculture soon. This study was conducted to understand the molecular mechanisms of …

Fenceline Weaning For Beef Cattle, C. L. Wright, R. J. Pruitt Oct 2005

Fenceline Weaning For Beef Cattle, C. L. Wright, R. J. Pruitt

SDSU Extension Extra Archives

Weaning time can be stressful for cows and calves. Under traditional weaning systems, changes in environment, diet composition, and pathogen exposure can reduce animal performance and result in health problems. In response to these challenges, interest in fenceline weaning has grown in recent years. Fenceline weaning is a management system in which the calves are removed from their dams but are allowed to see, hear, and smell their dams. Depending on the fencing used, physical contact may also be possible. Fenceline weaning has the potential to reduce stress related to transport, changes in environment, and diet adaptation. It may also …

Feeding Corn To Beef Cows, Cody Wright Sep 2005

Feeding Corn To Beef Cows, Cody Wright

SDSU Extension Extra Archives

In many western cattle operations, forages have traditionally been considered the most practical feedstuffs for wintering beef cows. However, in certain situations, the nutrient content of standing or harvested forages may be inadequate to meet the nutritional requirements of the beef cow for maintenance, gestation, or lactation. The availability of standing or harvested forages also may be limited, especially during drought years and(or) severe winters when the cost of medium- to low-quality forages may reach $80 to $100 per ton. Feeding corn grain may represent an economically viable alternative in each of these scenarios.

Feeding Scab-Infected Wheat To Livestock, Cody Wright, Alvaro Garcia, Jeff Held, Bob Thaler, Russ Daly, Martin Draper

SDSU Extension Extra Archives

Fusarium head blight, also called scab, is a disease of many small grain crops including wheat, barley, and rye. Oats can also be affected but generally with less damage. Scab is caused by the fungus Fusarium. Several species of Fusarium can cause the disease, but far and away the most common in South Dakota is Fusarium graminearum. This is the same fungus that causes Gibberella stalk rot in corn. When F. graminearum infections occurs in corn ears, the disease is referred to as Gibberella ear rot; it does not arrest kernel development. Generally, warm and wet conditions at wheat flowering …

Jackrabbit Football '05, South Dakota State University

Jackrabbit Football Media Guides (1950-2014)

On August 15, 2003, South Dakota State announced that the university would begin the process to reclassify from NCAA Division II to NCAA Division I status. The reclassification process requires five years, starting with the 2003-04 exploratory season and ending with an evaluation visit following the 2007-08 season. That would make SDSU a fullfledged member of NCAA Division I for the 2008-09 season. This year, 2005-06, is the Provisional Second Year meaning SDSU must be in full compliance with all Division I legislation and membership requirements including scholarship minimums and Division I scheduling.
