G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.

The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.

Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they …

G87-848 Control And Eradication Of Pseudorabies In Swine, Alex Hogg, George W. Beran

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses various plans to control and eradicate an increasingly important disease of swine--Pseudorabies.

Introduction and History

Pseudorabies (Aujeszky's Disease) is an acute, frequently fatal disease affecting most species of domestic and wild animals. The disease is caused by a virus of the Herpesvirus group, and is characterized by a variety of clinical signs--those involving the nervous and respiratory systems being particularly prominent. Pseudorabies is a persistent cause of loss in both cattle and sheep in many countries throughout the world.

Pseudorabies is an increasingly important disease of swine in the U.S. This increase in importance has paralleled the …

G87-849 Vaccinations In Sheep Flocks, Dale M. Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

High economic return per dollar invested can result from proper flock health management. Vaccinations are part of health management.

A preventive health program in modern sheep production systems is advisable. High economic return per dollar invested can result from proper flock health management. Health management is much more than a vaccination program. Vaccinations themselves are considered for a variety of reasons. These include disease risk management and strict prevention. Vaccinations may also be indicated in situations where management practices other than vaccine administration do not produce optimum health or economic benefits.

It is not feasible to outline one vaccination program …

G87-895 Pelvic Measurements For Reducing Calving Difficulty, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Pelvic measurements in heifers and bulls can be an important tool to help reduce the incidence and severity of calving difficulty. Calving difficulty results in a major economic loss to beef producers. This loss is estimated at $750 million annually nationwide. Calving difficulty increases calf death loss, cow mortality, labor and veterinary costs; it delays the return of cows to estrus and reduces conception rates. It also lowers calf weaning weight and market value, which results from breeding young heifers and cows to easy calving bulls to reduce calving difficulty. Studies show calf losses of 4 percent within 24 hours …

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.

G87-860 How To Interpret The Dhia-230 Somatic Cell Count Report, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This guide explains how to examine DHIA somatic cell count reports and use them as valuable aids in identifying the major causes of individual herds.

G86-783 Complete Rations -- Should You Feed Them?, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the advantages and disadvantages of feeding complete rations to dairy herds.

Using the complete ration system for feeding dairy cows has become increasingly popular. Nutritionists generally consider it the ideal method of feeding dairy cattle. Milk production per cow can be maximized, and feed and labor costs minimized, with this system. However, the necessary equipment is expensive and may be excessive for loose-housed herds of less than 100 cows.

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 …

G86-820 How To Maximize Income By Managing Days Dry, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This guide discusses the benefits of maintaining the optimum calving interval and offers suggestions for accomplishing this reproductive management technique.

Most dairy producers are aware that an optimum calving interval is 365 days. This is a normal lactation length of 305 days with a dry period of 60 days. This interval is often looked at as a goal to strive toward rather than a goal that must be reached to maximize income from the sale of milk.

G86-796 Growing Degree Day Requirements And Freeze Risk As A Guide To Selecting And Planting Corn Hybrids, Ralph E. Neild

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the growing degree day requirements for Nebraska's four corn-growing regions, and how using these requirements can aid in planting date decisions.

Variations between locations, between seasons at a particular location, between planting times at a particular location and season, and between the requirements of different hybrids result in differences in the number of days it takes for corn to mature. These variations in days are all closely related to differences in temperatures when the corn is being grown.

Ec86-113 A Guide For Planning And Analyzing A Year-Round Forage Program, Steven S. Waller, Lowell E. Moser, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Efficient grazing management programs cannot succeed without proper stocing rates. However, proper stocking rate alone will not insure a successful grazing program. Successful grazing management only occurs when all factors affecting production are manipulated properly: season of use; kind, class, and/or combination of animals; grazing distribution; grazing program; fertilization; pest control; and water management as well as stocking rate. The following suggestions in this circular are a guide to initial planning of new pastures and the modification of existing grazing programs.

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.

G86-815 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.

G86-824 Snow Mold Diseases Of Turfgrasses (Revised February 1991), John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

How to identify, prevent, and control the principal snow molds of turfgrass in Nebraska.

Principal snow molds of Nebraska turfgrass are Fusarium patch (pink snow mold) and Typhula blight (gray snow mold). Of these two, Fusarium patch is usually the most prevalent and, due to the general lack of continuous snow cover during winter, probably the most damaging. Although snow molds occur on most types of turf grown in Nebraska, fine-leaved turf types are more often seriously injured than coarser lawn grasses.

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 …

G86-775 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.

G86-821 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) …

G86-807 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 …

Ec86-2103 Safe Tractor Operations, Rollin D. Schnieder

University of Nebraska-Lincoln Extension: Historical Materials

No one deliberately has a tractor accident. Nevertheless, every year many farmers are killed or injured on, or because of, their tractors.

The causes of such accidents show that improper operation of the tractor or equipment accounts for the greatest percentage of accidents. Improper operation includes excessive speed, operating under the influence of alcohol and chasing cattle. Other accident causes are driving on too steep an incline and inexperience or immature drivers.

This extension circular contains safety hints on how to operate your farm equipment.
