G86-775 Prussic Acid Poisoning, Norman Shcneider, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Prussic acid poisoning and its treatment are discussed in this NebGuide, along with methods to reduce its occurrence.

Sudangrass, forage sorghum, and sorghum-sudangrass hybrids are often used for summer pasture, green chop, hay, or silage. Under certain conditions, livestock consuming these feedstuffs may be poisoned by prussic acid (HCN).

Exposure to excessive prussic acid--also called hydrocyanic acid, hydrogen cyanide, or cyanide--can be fatal. However, producers can manage and feed their livestock to avoid problems with prussic acid.

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.

G86-778 Do You Practice Good Milking Procedures?, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines good milking procedures to follow to assure high quality milk production while minimizing mastitis and other health problems.

Milking, or harvesting the milk crop, is a critical step between planting crops, building facilities, and paying bills on a dairy farm. While highly productive cows and a properly functioning milking system are essential, how the cows are handled and the milking system is used are equally important. Proper milking procedures are necessary to assure a bountiful harvest of high quality milk.

The nature of milk-secreting tissue and the anatomy of the udder make harvesting the milk crop impossible …

G86-799 Health Management And Recommended Vaccinations For Dairy Replacements, Duane Rice, R. Gene White

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the importance of having a good vaccination schedule, and provides recommendations on which vaccinations to give, depending on variables. Correct management decisions are necessary to realize maximum returns on investments in any dairy operation. Dairymen sometimes assume there is a quick remedy for health problems, but the prevention of disease is by far less expensive. Preventing health problems in the dairy herd goes much further than using a veterinarian to treat individual animals with emergency problems. A veterinarian with experience and a genuine interest in dairy cattle is essential to assist the dairyman with herd health problems. …

G86-809 Ecofarming: No-Till Sorghum Following Ecofallow Corn Or Sorghum, Robert N. Klein, Gail A. Wicks

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes using no-till sorghum in ecofallow rotations, including hybrid selection, planting and weed control methods, fertilizing, and possible insect and disease problems. The ecofarming system using a winter wheat-ecofallow corn or sorghum-fallow rotation has increased corn and sorghum yields because more water is conserved by controlling weeds with herbicides than with tillage. The land is fallowed the year following corn or sorghum and planted to winter wheat in the fall. Often enough precipitation is received during winter and/or early spring that another crop of sorghum could be grown instead of fallowing and planting wheat. If about 2000 lb/A …

G86-806 Chinch Bug Management (Revised January 1993), Barbara P. Spike, Robert J. Wright, Stephen D. Danielson

University of Nebraska-Lincoln Extension: Historical Materials

The life cycle and control of the chinch bug is discussed, with descriptions of possible management options.

The chinch bug is a native North American insect that can destroy cultivated grass crops, especially sorghum and corn, and occasionally small grains, such as wheat and barley. Broad-leaved plants are immune to feeding damage. Crop damage from this insect is most often found in southeast Nebraska and northeast Kansas and is associated with dry weather, especially in the spring and early summer months. Chinch bugs have few effective natural enemies. Ladybird beetles and other common insect predators found in Nebraska prefer to …

G86-802 Banvel And 2,4-D Damge To Fieldbeans And Soybeans, Roger G. Wilson, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the effects of Banvel and 2,4-D on soybean and fieldbean growth and yield. Banvel and 2,4-D are two herbicides commonly used for postemergence control of broadleaf weeds in corn, wheat, sorghum, pastures, and around field margins. Both herbicides can be moved off target by windy conditions at the time of spraying, or they can volatilize after spraying at temperatures above 85°F and drift off target. Fieldbeans and soybeans are both sensitive to Banvel and 2,4-D, and even rates as low as 0.001 lb/acre (1/100th of the use rate) can cause visual crop injury. The degree of crop …

G86-815 Reproductive Problems In Rams, Alan R. Doster, Dale M. Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

Systematic examination of all males to be used for breeding can prevent reproductive failure, minimize nonpregnant ewes, and increase numbers of lambs born early during lambing season.

The importance of using only highly fertile, healthy rams in breeding programs cannot be overemphasized. This is especially true in the case of small producers where only one ram is required. The ram represents an often neglected part of sheep production.

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) …

G86-822 How To Estimate A Dairy Herd's Reproductive Losses, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Remedies for herd losses caused by calving interval, dry periods, A.I. performance, and age at first freshening.

One of the major areas of lost income to the dairy producer is in the reproductive performance of the dairy herd. These losses are often overlooked because they are indirect costs. If producers could be given a monthly bill indicating the amount of money that improper reproductive management has cost them, then drastic changes would occur.

The majority of reproductive losses occur in the following areas:

1. Calving interval too long or too short.

2. Dry period too long or too short.

3. …

Heg86-209 Farm And Ranch Family Living Expenses--Taking Control, Kathleen Prochaska-Cue

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how families with an irregular income can control living expenses through use of a budget and cash flow plan.

Although farm and ranch family living levels have improved and become more comparable to nonfarm families, there will always be some important differences between these families with respect to managing the family living expenses. Income is irregular for many farm and ranch families and, in the past few years, has been insufficient to maintain the farm/ranch and family at a reasonable level of living. This guide is designed to help the farm or ranch family take control of …

G86-774 Western Corn Rootworom Soil Insecticide Treatment Decisions Based On Beetle Numbers, J. F. Witkowski, David L. Keith, Zb Mayo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how counting western corn rootworm beetles throughout the summer can be used to determine the need for insecticide applications the following spring.

Western corn rootworms are one of Nebraska's most serious insect pests of corn. Eggs laid in the soil from late July through September overwinter and begin hatching in late May or early June. Larvae feed on corn roots, causing plants to lodge, and may reduce grain yields. The greatest injury usually occurs from late June to mid-July, when all corn roots may be destroyed if infestations are heavy. Fully grown larvae pupate in the soil …

G86-789 Human Lice And Their Control, Shripat T. Kamble, David L. Keith, Wayne L. Kramer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide includes information on biology and control of three species of lice that infest humans.

Pediculosis (lice infestation) in humans has been known since ancient times. Three types of lice that infest humans: 1) head lice, 2) body lice, and 3) crab or pubic lice.

Lice are small, flat, dirty white to grayish black, wingless insects. Their legs are short and stout, with a large claw on each leg for grasping and holding onto hair. Lice have piercing and sucking mouth parts. These insects are blood feeders and require close contact with human hosts.

G86-792 Spiders, David L. Keith, Stephen D. Danielson, Timothy P. Miller

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the most common species of spiders found in Nebraska, including the black widow and brown recluse, and how to control them.

General Description and Habits

Spiders can be distinguished easily from insects. All spiders have two major body regions and four pair of legs; insects have three body regions and three pair of legs. Spiders vary widely in color, shape, size, and habits. All produce venom that is poisonous to their normal prey. Few spiders are considered dangerous to humans, however. These animals are predacious by nature and use their venom, which is injected through hollow fangs …

G86-826 Irrigating Alfalfa (Revised October 1990), Delynn Hay

University of Nebraska-Lincoln Extension: Historical Materials

Alfalfa has certain water use characteristics. Knowing these and how to monitor soil moisture, apply water, manage irrigation, and schedule water application will help you grow a high quality crop. Irrigation makes it possible to grow high quality alfalfa throughout Nebraska on a wide variety of soils. Alfalfa, relatively drought tolerant, will produce yields almost proportional to the amount of water available to the crop. This means that alfalfa will respond favorably to irrigation. Because of its longer growing season, the seasonal water requirement of alfalfa will be higher than for other crops. Irrigation management must consider characteristics such as …

G86-807 Where Do Weeds Come From?, John Furrer, Robert G. Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses weed seed entry and loss from the soil, and provides examples of the density and diversity of the soil weed seed population. Weed Seed in the Soil Most weeds owe their beginning to seed in the soil. The soil acts as a seed storage reservoir and a growth medium for weedy plants. The kind or species and numbers of seed in the soil is closely linked to the cropping history of the land. Grasslands contain seed associated with grassland plants and cropland contains seed affiliated with weeds growing on cultivated land. Grasslands that have been cultivated and …

G86-794 Enterotoxemia In Lambs, Dale M. Grotelueschen, Duane N. Rice

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the causes, clinical signs, diagnosis, treatment, and prevention methods of this potentially fatal disease.

Enterotoxemia, which is also known as "overeating" or "pulpy kidney" disease, is a highly significant and costly disease problem for the sheep industry. Proper preventive practices are strongly recommended to sheep producers in order to avoid death loss from this disease.

The word "enterotoxemia" can be broken down into three parts that can be an aid in understanding the disease. The term "entero" refers to intestine; "tox" refers to toxin or poison; and "emia" refers to blood. Thus, from "intestinal toxin in the …

G86-795 Antibiotic Use In Animals, Duane N. Rice, E. Denis Erickson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides general guidelines about some of the problems that can occur when using antibiotics in treating animals.

Antibiotics are frequently used, and misused, by animal owners in an attempt to remedy disease problems. This use is encouraged by drug company sales efforts, economic pressures, and easy access to the products.

Improper use of antibiotics is costly, detrimental, and may result in: 1) delayed diagnosis; 2) ineffectiveness; 3) toxicity (poisoning); 4) allergic reactions; and 5) drug residue contamination of food animal products.

After evaluating possible benefits and risks, determining whether or not to use antibiotics for treatment depends on …

G86-825 Existing Buildings--Remodel Or Abandon?, Gerald R. Bodman, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

Just because a building is there does not mean that remodeling is the best option. Here are ten factors of prime importance when deciding if a building is suitable for remodeling.

As livestock production enterprises change, many producers ask, "Should I remodel this building or abandon it and start over?" A sound answer requires careful evaluation of the intended use of the building being considered for remodeling. The immediate future and projected long range production goals must be considered. We've all read about successful remodeling projects, but few of us ever hear about the large number of remodeling projects that …
