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.

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.

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 …

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 Sep 2005

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 …

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 …

Interactions Among Western Corn Rootworm (Coleoptera: Chrysomelidae), Yellow Foxtail, And Corn, M. M. Ellsbury, K. R. Banken, S. A. Clay, F. Forcella Jun 2005

Interactions Among Western Corn Rootworm (Coleoptera: Chrysomelidae), Yellow Foxtail, And Corn, M. M. Ellsbury, K. R. Banken, S. A. Clay, F. Forcella

Agronomy, Horticulture and Plant Science Faculty Publications

Field studies at sites with two contrasting soil types investigated effects from the presence of yellow foxtail [Setaria pumila (Poir.) Roem. and Schult.], established in bands parallel to corn rows, on western corn rootworm (Diabrotica virgifera virgifera LeConte) survival, corn root injury, lodging, biomass production, and yield. Results suggested that the presence of foxtail as an alternate host inßuenced the degree and progression of corn rootworm damage and adult emergence in a givenlocality. Rootworm adults emergedlater from foxtail band areas and had smaller head capsule size than did individuals from areas without foxtail, consistent with earlier Þndings that foxtail in …

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 …

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.
