G91-1047 Acidosis, Rick Stock, Robert Britton

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses why acidosis occurs, its economic considerations, and methods to prevent and treat acidosis.

Acidosis is the most important nutritional disorder in feedlots today. Caused by a rapid production and absorption of acids from the rumen when cattle consume too much starch (primarily grain) or sugar in a short period of time, acidosis causes cattle to be stressed. As long as cattle are finished on grain, cows are grazed on cornstalk fields (grain consumption) or high energy (grain) diets are fed to dairy cows, acidosis will be an important problem.

Cattle evolved digesting roughages that ferment slowly in …

G91-1048 Average Composition Of Feeds Used In Nebraska, Rick Stock, Rick Grant, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Analyses of frequently used feedstuffs are shown on a dry matter basis in the following table. Because the moisture content of feedstuffs varies widely, formulating rations on a dry basis contributes to accuracay in feeding cattle, compared to formulating on "as-fed" analyses.

Nf91-28 Psittacosis (Chlamydia Psittaci Infections) In Pet Birds, Eva Wallner-Pendleton

University of Nebraska-Lincoln Extension: Historical Materials

Companion birds continue to increase in popularity as pets in the United States. Birds most frequently kept belong to the family psittacidae, or the parrot family. Although domestic breeding of parrots is becoming more widespread, a large number of birds are still imported from outside the United States. By law, these birds must enter the country through quarantine stations. There they spend at least 30 days and are tested for disease and fed food containing tetracycline, an antibiotic. The antibiotic treatment is to hopefully eliminate infections with Chlamydia psittaci, the bacterium that causes psittacosis.

13.2.8. Rescue And Rehabilitation Of Oiled Birds, Sallie Welte, Lynne Frink

Waterfowl Management Handbook

Oil contamination of waterfowl and seabirds has been documented as a significant cause of morbidity and mortality in birds for more than 50 years. Each year more than one million birds may die from oil contamination in North Atlantic waters alone; worldwide mortality is unknown.

Of special concern is that many of the seabirds commonly affected are not prolific breeders, and assessment of each species’ status is handicapped by the difficulty of accurately monitoring trends in marine bird populations.

Oiled bird rehabilitation is an intensive, crisis-oriented response, requiring an experienced management agency, specialized medical expertise, stockpiles of specially designed equipment, …

13.4.6. Strategies For Water Level Manipulations In Moist-Soil Systems, Leigh H. Fredrickson

Waterfowl Management Handbook

Water level manipulations are one of the most effective tools in wetland management, provided fluctuations are well-timed and controlled. Manipulations are most effective on sites with (1) a dependable water supply, (2) an elevation gradient that permits complete water coverage at desired depths over a majority of the site, and (3) the proper type of water control structures that enable water to be supplied, distributed, and discharged effectively at desired rates. The size and location of structures are important, but timing, speed, and duration of drawdowns and flooding also have important effects on plant composition, plant production, and avian use. …

13.1.3. Life History Strategies And Habitat Needs Of The Northern Pintail, Leigh H. Fredrickson, Mickey E. Heitmeyer

Waterfowl Management Handbook

The northern pintail (hereafter pintail) is a common dabbling duck distributed throughout the Northern Hemisphere. Since 1955, the breeding population in North America has averaged 5,566,000, fluctuating between 10,124,000 (1956) and 2,471,000 (1989; Fig. 1). Pintail numbers are especially sensitive to habitat conditions that reflect the wet–dry cycle in the shortgrass prairie breeding areas of south-central Canada and the northern Great Plains of the United States. Populations of pintails also are affected by habitat conditions in key wintering areas, such as the Central Valley of California and Gulf Coast marshes. When wintering areas are fairly dry, birds have fewer resources …

Molecular Epidemiologic Techniques In Analysis Of Epidemic And Endemic Shigella Dysenteriae Type 1 Strains, Nancy A. Strockbine, Julie Parsonnet, Katherine Greene, Julia A. Kiehlbauch, I. Kaye Wachsmuth

United States Public Health Resources

During 1988 the number of Shigella dysenteriae type 1 infections reported in the United States increased fivefold. To determine if recent isolates from Mexico were related to those that caused epidemics of dysentery worldwide, Southern hybridization analysis was done with Shiga toxin and ribosomal RNA gene probes. Western hemisphere and Eastern Hemisphere strains differed by the size of a single EcoRI fragment carrying the Shiga toxin genes. Three ribosomal DNA (rDNA) patterns were observed, which correlated with the strain;s continental origin for 81 of 83 isolates tested. Together the Shiga toxin and rDNA probe results indicated that recent Mexican …

His …

Use Of A Simulation Model To Evaluate The Influence Of Reproductive Performance And Management Decisions On Net Income In Beef Production, L. A. Werth, S. M. Azzam, Merlyn K. Nielsen, J. E. Kinder

Department of Animal Science: Faculty Publications

A stochastic dynamic model of reproduction and a deterministic cow-herd economic simulation model were used to evaluate how management decisions and reproductive performance interact to influence net income in a cow-calf operation (1,000 cows) for 1 yr of production. The stochastic model was used to determine herd performance when length of breeding season (45, 70, or 120 d) interacted with three postpartum intervals of an estrus (48, 65, or 90 d) and three conception rates at first service (60, 70, or 80%). Short, moderate, and long postpartum intervals were used to reflect differences in reproductive performance. In addition, replacement heifers …

Continuity And Change On The Twentieth-Century Farm: The Gists Of South Dakota, 1921-71, James Marten

Great Plains Quarterly (through 2013)

When Gladys Leffler Gist remarked in her reminiscences that she and her husband Ray had witnessed "considerable 'for better and for worse'" during their forty years together, she could just as well have been describing the "marriage" between farmers and the agricultural economy during the same period. Depression and drought, of course, challenged those people making their livings from the land and in many ways dominated their impressions of those years. Of more long-term importance, however, were the "vast and fundamental changes" that, according to Gilbert Fite, stemmed from the "application of new technology, chemistry, and plant and animal sciences" …

Feeding Value Of Grain Sorghum For The Lactating Sow, G. F. Louis, A. J. Lewis, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Two experiments were conducted to investigate the effects of a corn-soybean meal (CSBM) and a sorghum-soybean meal (S-SBM) diet on reproductive performance and nutrient utilization by sows. In Exp. 1,75 sows (39 gilts; 36 primiparous) were fed either a C-SBM or a S-SBM gestation diet from breeding to d 109, On d 110, sows were assigned to lactation diets; half of the sows from each dietary treatment were assigned to a lactation diet based on the opposite grain. Sow weight change from d 54 to farrowing was greater (P < .06) for sows fed S-SBM than for sows fed C-SBM. There was no difference (P > SO) in weight change of sows during lactation. Feed consumption during …

13.4.7. Managing Beaver To Benefit Waterfowl, James K. Ringelman

Waterfowl Management Handbook

Aside from humans, no other organism has the capacity to modify its environment as much as the beaver. In doing so, beaver create wetlands that provide valuable waterfowl habitats. Because beavers are widely distributed in North America (Fig. 1), beaver ponds can benefit waterfowl during breeding, migrating, and wintering periods. Mismanaged beaver populations, however, can severely degrade riparian habitats and become a costly problem. The key to successfully managing beaver for waterfowl benefits is understanding the values of beaver ponds in meeting the seasonal needs of waterfowl. Beaver populations must then be managed to provide these benefits in a self-sustaining …

13.4.18. Chufa Biology And Management, James R. Kelley Jr., Leigh H. Fredrickson

Waterfowl Management Handbook

Chufa (Cyperus esculentus) is an emergent perennial sedge that is common in seasonally flooded wetlands. Although chufa is common in many States, it is most abundant in the Southeast, including the Mississippi alluvial valley (Fig. 1). Belowground biomass of chufa, especially the tubers, serves as a valuable food source for waterfowl and cranes. Chufa tubers rank tenth among the most important waterfowl foods in the United States.

G91-1010 Managing Corn And Sorghum Residues During The Ecofarming Fallow Period, Robert N. Klein, Gail A. Wicks

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to maintain an appropriate residue cover with ecofarming in the fallow period before winter wheat to reduce soil erosion and conserve soil moisture. Ecofarming is a system of controlling weeds and managing crop residues throughout a crop rotation with minimum use of tillage. This will reduce soil erosion and production costs while increasing weed control, water infiltration, moisture conservation and crop yields. In the winter wheat-ecofallow corn or grain sorghum-fallow rotation, corn or grain sorghum is no-till planted into winter wheat stubble in May. During the previous summer or fall the winter wheat stubble was treated …

G91-1034 Evaluating The Feeding Value Of Fibrous Feeds For Dairy Cattle, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes what makes fiber unique as a nutrient, how it's measured, and the impact different dietary fiber levels have on milk production and feed intake.

Fiber content of feed or forage affects its feeding value. Understanding fiber and how it is used is necessary to properly feed dairy cows. Each of the following topics will be addressed to better understand fiber nutrition in the dairy cow:

1. What is fiber?

2. How will too little or too much fiber in the diet affect the cow's metabolism and subsequent production?

3. What are optimal levels of fiber in the …

G91-1027 Protein And Carbohydrate Nutrition Of High Producing Dairy Cows, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the protein and carbohydrate requirements for milk production by dairy cows, and feeding guidelines to meet those requirements.

Crude protein makes up 14 to 19 percent, and carbohydrates 65 to 75 percent of the total ration dry matter in common dairy cow diets. As milk production per cow increases above 19,000 to 20,000 pounds per year, understanding how these nutrients are used by the dairy cow for milk production allows the formulation of diets that optimize solids-corrected milk production.

G91-1041 Feeding The Bovine Somatotropin (Bst) Treated Dairy Cow, Rick J. Grant, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Proper feeding management of dairy cows treated with bovine somatotropin is emphasized.

When dairy producers decide to use bovine somatotropin (BST) in their herds, proper nutritional management is critical to its success.

The final decision to use BST is likely an economic one: will the use of BST in a producer's operation generate a positive cash flow?
