Effects Of Body Condition On Reproductive Performance Of Range Beef Cows, R.J. Pruitt, P.A. Momont

South Dakota Beef Report, 1987

Simnental-Angus crossbred cows were fed differing Levels of nutrition from December to May in each of 3 years to create a wide range in cow body condition or fleshiness at the beginning of the calving season (beginning mid-March) and when turned to summer pasture (early May) 1 month prior to the beginning of the breeding season (early June). Cows that were fleshier in March, May or June cycled earlier. Cows that were fleshier at the beginning of the breeding season calved earlier the following years. For cows that calved Late in the calving season, body condition prior to calving, in …

G87-851 Improving Reproductive Performance And Productivity Of Beef Herds, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

NebGuide discusses management practices that can be used to improve reproduction and productivity of beef herds. The major objective of cow-calf producers should be to wean a calf from each cow every year. The average calf crop weaned in Nebraska is estimated at 80 calves weaned per 100 cows in breeding herds. A realistic goal is 90 to 95 calves weaned per 100 cows.

Effects Of Level Of Energy Supplement In Early Winter And Level Protein After Calving On Beef Cows Grazing Native Range, R.J. Pruitt

South Dakota Beef Report, 1986

Simmental-Angus crossbred cows grazing native range near Cottonwood, SD, were fed two precalving levels of energy supplement and two postcalving levels of protein supplement. Cow weight change and reproductive performance were similar for all treatments. Although calves from cows supplemented with higher levels of energy gained faster from birth to early May, gains to weaning were similar for all treatments.

G86-797 Causes Of Vaccination-Immunization Failures In Livestock, Duane Rice, E. Denis Erickson, Dale Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses reasons why vaccinations fail to provide immunity against disease, and how to prevent this from happening.

To comprehend the many reasons for vaccine failure, it is important to understand how animals and humans have the ability to resist infectious diseases. It is also important to know what a disease is and how it affects the animal.

According to Stedman's Dictionary, disease is an interruption, cessation or disorder of body functions, systems or organs. Diseases may be obvious even to the untrained eye, or detectable only by sophisticated testing procedures (subclinical disease). Serious irreversible damage may be …

Mp51 Distillers Grains, Glen Aines, Terry Klopfenstein, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

In the conventional production of alcohol from grain for fuel, byproducts are produced with excellent feeding value for ruminants. Appropriate use of these byproducts aids the efficient production of animals and enhances the economics of alcohol production. In the fermentation of corn to produce alcohol, the starch in the corn is converted to alcohol and carbon dioxide. The nutrients in the corn other than starch are concentrated about three times because corn is about two-thirds starch. Even though starch is high in energy, the one-third of the corn remaining in the byproduct after fermentation contains as much energy per pound …

G86-814 Using Ram Lambs For Breeding, Ted Doane

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how ram lambs can be most efficiently used in a breeding program and provides management suggestions for a successful program.

Are you planning to use a ram lamb this breeding season? If so, you should consider the capabilities and limitations of ram lambs.

It may be true that some well-grown, aggressive, vigorous, highly fertile ram lambs can settle 50 ewes and maybe more. However, these rams are exceptions. A good rule to follow for practical ram management is 15 to 20 ewes for a ram lamb and 35 to 50 ewes for a mature ram.

G86-821 Weaned Pig Management And Nutrition (Revised August 1992), Duane Reese, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Temperature, space, health considerations, dietary nutrient allowances, feeding management and more are covered here. The weaning age of pigs farrowed in Nebraska is variable. While the average age at weaning is about four weeks, the range is from two to eight weeks. However, industry surveys indicate that more than 50 percent of the pigs in the United States are weaned at 28 days of age or earlier, with the majority weaned between three and four weeks of age. This trend towards earlier weaning is expected to continue with advances in management, housing, health and nutrition. Earlier weaning (under 28 days) …

G84-716 Management Of The Weanling Calf, Paul Q. Guyer, Donald B. Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines a program for preventing sickness and death losses in newly weaned calves, including stress prevention, vaccinations, nutrition, and treatment of sick calves.

Sickness and death loss following weaning robs both calf producers and cattle feeders of potential profits. The weanling calf has not acquired adequate immunity to the variety of diseases that plague the beef industry. At weaning and/or shipping, the calf is usually subjected to various stresses, in addition to being separated from its mother, that contribute to disease outbreaks. A program for minimizing weight loss, sickness, and death in newly weaned calves should include: 1) …

G84-696 Small Grains For Silage Or Hay, Paul Q. Guyer, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the advantages and disadvantages of using small grains for silage or hay, including handling, storage, feeding, animal performance, and nitrate toxicity potential.

Small grain crops are potentially important sources of high quality forage. Harvesting small grains for hay or silage rather than as grain may mean increased dollar returns per acre. Small grain silage or hay represents more total nutrient production per acre than harvest as grain and, when fed to ruminants, results in increased animal production.

Too Much Of A Good Thing: Protein And A Dog's Diet, Dana H. Murphy

Pets Collection

Where the analysis done by Kronfeld on stress in dogs goes awry is in its implication that this conversion of protein reserves occurs during a mild or transient period of emotional turmoil. In point of fact, catabolism of proteins only begins after an extended duration of severe stress, as a consequence of an extreme condition like a long sled race or a bad infection. Therefore, a mildly stressed animal probably needs carbohydrates (and perhaps fats) far more than supplemental protein, since the former can be quickly and easily converted into bodily fuel. And in the case of the stress induced …

G80-493 Developing Replacement Beef Heifers (Weaning-Breeding), Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the proper selection, nutrition, breeding, and management of replacement beef heifers from weaning to breeding. Proper selection and development of replacement heifers is one of the most important management programs in beef production. Replacement heifers should be selected and managed so they will conceive and calve early in the calving season, provide adequate milk production, and rebreed and calve every 365 days. Heifers bred as yearlings to calve as two-year-olds will produce an extra calf in their lifetime compared to heifers calving as three-year-olds, without detrimental effects on mature size, milk production, or calf weaning weights. The …

Production Of Quick-Cooking Beans (Phaseolus Vulgaris L.): Investigations On Antinutrients And Quality, Vishalakshi G. Iyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three bean varieties, namely, great northern, kidney, and pinto (Phaseolus vulgaris L.), were subjected to several physico-chemical treatments to reduce their cooking time. Soaking in a combination of salt solutions (sodium chloride, 2.5 percent+ sodium bicarbonate, 1.5 percent+ sodium tripolyphosphate, 1.0 percent + sodium carbonate, 0.5 percent) resulted in 80-85 percent reduction in cooking time. Irradiation (Γ-rays) at 500 Krads of soaked and dehydrated beans caused nearly 50 percent reduction in cooking time. High temperatures (37 and 45°C) and pH (9.0) caused greater water imbibation and total solids loss than room temperature (22°C) and pH 7.0. Organoleptic evaluation of beans …

Investigations On Improvement Of Acceptability And Evaluation Of The Nutritive Value Of Processed Cabbage And Its Effects On The Tumorigenicity In Mice, Chareonsri Srisangnam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this investigation have been to study the acceptability and nutritive value of processed cabbage and to elucidate the effects of chronic administration of cabbage on the activity of a colon tumorigen, 1,2-dimethylhydrazine (DMH). The organoleptic unacceptability of cabbage in spite of its high nutritional and economic values governed the choice of this cruciferous vegetable for this work.

Cabbage samples were blanched with steam, chemical solutions, and microwaves. Microwave blanching led to a "burnt spot" effect and to a relatively greater loss in weight of the vegetable. Blanching in solution involved boiling of cabbage with a chemical solution …

Sodium And Potassium Nutrition Studies Of Halogeton Glomeratus (M. Bieb) C.A. Mey, Ali A. Alhelal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C.A. Mey when grown in nutrient solution, caused the solution pH to decrease very rapidly as plants increased in size, especially during the fifth week of growth. This might be attributed to hydrogen ion exchange for cations. Also, the cation uptake, especially K and Na, may exceed that of the major anions. The control of pH is effective in increasing shoot weights markedly.

In general there was no difference between plants grown at the same NaCl concentration at low and high relative humidity. An increase in plant size, shoot weights, leaf length and diameter was detected …

G79-467 Livestock Water Quality, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this report is to discuss what is involved in livestock water quality and how one goes about getting an analysis that will help in determining this quality, and to assist in the interpretation of such an analysis.

A successful livestock enterprise requires a good water supply, both in terms of quantity and quality. While shortage is obvious to the stockowner, he sometimes needs the help of a laboratory in evaluating the quality of a supply. The purpose of this report is to discuss what is involved in livestock water quality and how one goes about getting an …

G79-434 Feeding Guides For The Ewes, Ted Doane

University of Nebraska-Lincoln Extension: Historical Materials

In utilizing the information in this publication, the sheepman and those advising him must keep in mind the ultimate objectives of the production program in question.

The major problem in nutrition is the definition of the desired animal function. Maintenance of the ewe, for example, is generally thought of in terms of the dry ewe. Yet maintenance of productive functions is a constant cost in ewe nutrition, whether she is pregnant, lactating, dry, or in the process of being bred for another year.

In utilizing the information in this publication, the sheepman and those advising him must keep in mind …

G79-477 Beef Herd Management Calendar, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This publication contains a brief outline of management practices to be followed at various stages of the cow's reproductive cycle or at various times of the year.

Good management is the key to a successful beef production program. A high capital requirement and a relatively low return emphasize the need for effective management to maximize the profit potential of beef cows.

G78-395 Feeding Corn And Sorghum Silages To Beef Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Corn and sorghum silages are versatile feeds that can be supplemented so that they are satisfactory for part of most growing and finishing rations. Harvesting corn as silage and planting forage sorghums for silage have the advantage that they maximize beef production per acre compared to harvesting these crops by other methods and other cropping programs. Another important advantage is that harvesting, storage and feeding can be completely mechanized.

However, as the costs of machinery, fuel, and labor have increased, the cost of harvesting silage has increased more rapidly than harvesting as grain.

Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel

Aspen Bibliography

Vegetation and soils were sampled in adjacent 40-year-old stands of red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), white spruce (Picea glauca (Moench.) Voss), and aspen (Populus tremuloides Michx., P. grandidentata Michx.) on a very fine sandy loam soil in north-central Minnesota. Total tree biomass was greatest for red pine followed by by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and …

A Self-Instructional, Multi-Media Approach To Facilitate The Teaching Of The Index Of Nutritional Quality, Claudia Kay Probart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A review of the literature dealing with nutrition education established the following: (a) that there is a need for nutrition education at the elementary school level; (b) that elementary teachers do not always have the background or motivation to meet this need for nutrition education; and (c) that new educational methods that are easier to understand and more highly motivating are needed.

The Index of Nutritional Quantity (INQ), a nutrient density concept, was developed at Utah State University to answer the need for easily understood and motivating nutrition information. The INQ method of nutrition education has been used and considered …

G77-350 Mineral Nutrition Of Range Beef Cattle, Marvin W. Heeney

University of Nebraska-Lincoln Extension: Historical Materials

Minerals play a very important role in the well-being of the range beef herd. Minerals are essential for practically all of the metabolic functions of the beef animals. Minerals are classified as 1) major and 2) minor or trace. The major minerals include calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulfur. The trace minerals include copper, cobalt, iodine, iron, manganese and zinc.

Each mineral is discussed here in terms of its function, deficiency symptoms and availability in the range beef cattle diet.

G77-386 Wheat In Poultry Rations, T.W. Sullivan, E.W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This publication examines the advantages and disadvantages of wheat as a component of poultry feed.

Wheat is usually considered a source of human food rather than an ingredient for poultry and livestock feeds. This is especially true in the United States, where corn, milo and other feed grains are abundantly produced. In recent years one of every two bushels of wheat produced in the United States has been exported. If world production and supplies of wheat are high, a surplus develops and wheat prices are lowered. When this situation occurs wheat becomes an attractive alternative to corn or milo in …

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …
