University of Nebraska-Lincoln Extension: Historical Materials

This report contains historical price data for the major crops and livestock commodities produced in Nebraska. Prices received by producers are reported for 1960-2005 for most of the commodities.

The data was compiled from Nebraska Agricultural Statistics Service and Agricultural Prices, National Agricultural Statistics Service, USDA; Oil Crops Situation and Outlook, Economic Research Service, USDA; Cotton and Wool Outlook, Economic Research Service, USDA; and Livestock and Grain Market News, Agricultural Marketing Service, USDA. Sources of prices for each commodity are indicated on the tables.

Ec00-279 Synchronizing Esetrus In Beef Cattle, Richard J. Rasby, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Synchronization of estrus (heat) involves manipulating the estrous cycle of beef females in a herd so they can be bred at approximately the same time. There are several traditional protocols available for synchronizing estrus among beef females.

This extension circular discusses the programs and protocols used in synchronizing estrus in the beef cow.

G97-1314 Medication Withdrawal In Beef Cattle, Dicky D. Griffin, Dale Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide lists the current withdrawal times for medications used in beef cattle.

Using proper livestock medications is very important. Proper use not only ensures maximal benefits from the medication but minimizes the chances of an unwanted residue. The National Cattlemen's Beef Association has worked hard to develop a premiere quality assurance program. In conjunction with other national and state beef and veterinary associations, the Beef Quality Assurance program now extends to almost every state in the nation. As a result, the safety and quality of beef has never been better. The outstanding record includes having an extremely low rate …

G95-1238 1995 Usda Sire Evaluation Changes, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This publication discusses the 1995 USDA Sire Evaluation Report and its impact for dairy producers.

The January 1995 USDA Sire Evaluation Report incorporates changes that will not only increase the accuracy of prediction for cow and sire evaluations, but also includes a base change. Major changes included:

new Mature Equivalent Factors,

adjustments incorporated for days open,

and the genetic base year changed to 1990.

Let's discuss each change and look at how these changes will effect the 1995 proofs.

Ec90-268 Nebraska Beef Weaning-Yearling Worksheet

University of Nebraska-Lincoln Extension: Historical Materials

EC90-268, Nebraska Beef Weaning-Yearling Worksheet helps farmers and ranchers keep track of details on a an animal's performance through a given year.

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.

G85-741 Estrous Synchronization For Beef Cattle, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the potential benefits of estrous synchronization, how the products and programs work, and the results and costs involved. Estrous (heat) synchronization can help beef producers improve production efficiency and economic returns. Controlling estrus and ovulation in cycling females means breeding is completed in a short period of time. Instead of females being bred over a 21-day period, synchronization can shorten the breeding period to less than 5 days, depending on the program selected. The use of synchronization has great potential for improving beef production, but it requires good management for success. Producers should understand the advantages, as …

G85-755 How To Set Goals For Your Breeding Program, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to determine which trait(s) to select for, and how multiple trait selection affects genetic progress.

Dairy producers are often concerned with placing emphasis on different production traits in their breeding program. Selecting on only economically important traits should be the objective of every producer. The use of artificial insemination (A.I.) sires is the most economical and productive way to increase the genetic potential of the herd.

A cow's record is a measure of her genetic potential, which is modified by the environment in which she is kept. Environmental factors that directly influence a cow's record include …

G83-666 Breeding Soundness Examination Of Beef Bulls, James A. Gosey

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes factors to consider when evaluating a beef bull's reproductive ability. These include the reproductive tract, semen and mating desire. A herd bull that will settle a higher percentage of cows during a limited breeding season is essential to a successful cow-calf operation. In many cow-calf operations, however, the bull's role in the herd's reproductive performance is taken for granted. The bull's fertility is several times more important than that of a cow. Each bull can be expected to settle as many as 30 cows. The bull also contributes half of the genetic potential of the entire calf …

G81-539 Assisting The Beef Cow At Calving Time, Gene H. Deutscher, Donald B. Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This publication acquaints cattle producers with calving management principles to minimize calf loss. The objective is to deliver a live calf from every cow. Six to ten percent of all calves born in beef cow herds in the U.S. die at or soon after birth. Approximately half of those deaths are due to calving difficulty (dystocia). This multi-million dollar annual loss is second only to losses from cows failing to conceive. Calving difficulty has received much more attention in recent years, primarily because of the mating of larger European breeds of bulls to British breeds of cows. Increased calving problems …

G80-495 Managing Two-Year-Old Beef Heifers (Calving - Rebreeding), Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the nutrition and management practices recommended for beef heifers during precalving, calving, and early lactation periods. Proper development of replacement heifers has a great influence on the success of calving and rebreeding them as two-year-olds. NebGuide G80-493, Developing Replacement Beef Heifers (Weaning-Breeding), points out that proper selection, adequate nutrition, and judgment in sire selection are all important management factors for developing heifers into high producing cows. With good management before breeding, a high percentage of heifers should be bred early in a short breeding season. Heifers should be pregnancy checked and the open ones culled. Thereafter, the …

G75-232 Cow-Calf Herd Health Program (Revised April 1993), Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

Establishing a good cow-calf herd health program is a necessary step in the right direction if a profit is to be realized. The objective of any beef herd health program should be for 100 percent of the cows to produce a calf weighing enough to provide a reasonable return.

This NebGuide discusses essentials of health management in beef cow operations.
