G89-915 Testing Livestock Feeds For Beef Cattle, Dairy Cattle, Sheep And Horses, Rick Grant, Bruce Anderson, Richard J. Rasby, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides tips on how to determine feeds you should analyze and nutrients to measure. It tells how to interpret the results of feed analysis.

Why Test Feeds?

Nutrient concentration can vary considerably in feeds, especially forages. Protein in alfalfa hay can range from 10 to 25 percent or more of the dry matter; grass hay will contain between four and 18 percent protein.

Use feed tests to target specific feeds to different livestock. Feed high quality forage to the most productive livestock or when nutrient needs are highest. Feed lower quality forage to animals with lower nutrient needs. …

G89-989 How To Interpret The New Animal Model For Dairy Sire Evaluation, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

In question and answer format this NebGuide addresses changes in genetic evaluations of both dairy cows and sores.

Why is the United States Department of Agriculture (USDA) changing the dairy sire and cow evaluation system?

The answer is simple. The Animal Model for genetic evaluations is more accurate than the old Modified Contemporary Comparison Method (M.C.C.). Previously the major limiting factors to implementing the Animal Model were computing costs and memory requirements. With the advent of new Super Computers, the computations are feasible on a national scale.

What is the Animal Model?

The Animal Model simultaneously evaluates cows and sires …

G89-942 Can You Afford To Use Bovine Somatrophin (Bovine Growth Hormone)?, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider before using Bovine Somatrophin in your dairy herd are covered here.

Much has been written recently about the effect of administering Bovine Somatrophin (BST) to dairy animals. The expected increase in income that could be generated by the use of BST catches producers' attention.

Before any producer uses BST, however, there are a few questions that should be addressed. The most crucial is, "Can BST administration be cash flowed in my dairy operation?"

The answer to this question is dependent on three crucial areas--your current herd average, herd management situation, and the costs involved in the application …

G89-952 Estrus (Heat) Detection Guidelines, Jeffrey F. Keown, Duane N. Rice

University of Nebraska-Lincoln Extension: Historical Materials

Ways to spot cows in heat are covered in this NebGuide.

Several factors are essential in maintaining a herd's reproductive health. Among the most important are: (1) maintaining accurate records, (2) knowing the visual signs of estrus (heat), (3) using proper heat detection aids, and (4) maintaining a herd health program.

By taking the four basic steps listed above, the expected calving interval for dairy animals will be close to the recommended 12 to 13 months. Beef producers need to strive for a 12-month calving interval to maintain a profitable enterprise.

This 12- to 13-month calving interval returns the most …

Ec87-726 Mastitis Control Guidelines, Gerald R. Bodman, Duane N. Rice, Don J. Kubik

University of Nebraska-Lincoln Extension: Historical Materials

These mastitis control guidelines were prepared by UNL personnel based on current literature and experience with the Nebraska mastitis control program, the demonstration herds, and many on-site dairy farm evaluations. This information will help producers and others in the dairy industry to understand, establish and maintain a comprehensive mastitis control program. Recommendations and procedures presented in the guidelines will allow the producer to develop an effective mastitis control program. When the recommendations are coupled with a conscientious and dedicated attitude, the result will be less mastitis and more better-quality milk at a lower production cost.

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.

Losses to mastitis are estimated at more than $200 per cow annually. In Nebraska annual losses total more than $20 million dollars.

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 …

G83-678 Producing Milk With A Low Bacteria Count, Stanely E. Wallen, Don J. Kubik, Stephen L. James, Daniel J. Borer, Gerald R. Bodman, E. Denis Erickson, Duane N. Rice, Philip H. Cole, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides cleaning, sanitizing, mechanical, environmental and other procedures to follow to assure a low bacterial count in milk. Bacteria are tiny, rapidly reproducing microorganisms that are too small to be seen without a high power microscope. Their very tiny size makes it very difficult to eliminate them from dairy equipment. Because bacterial growth in milk may cause spoilage and possibly human illnesses, a low bacterial count is one of the best indicators of top quality milk. Milk will almost always be of top quality if properly harvested from healthy, clean cows with clean equipment, cooled quickly and kept …

G77-360 Balancing Corn Silage Dairy Rations, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

The grain required to balance a ration high in corn silage is much different from the grain needed when feeding high amounts of alfalfa hay. The most common problem is failure to properly balance for protein and calcium. This NebGuide discusses the points to take into account in balancing rations high in corn silage.

These facts and other economic conditions in Nebraska are published this year as the …

Rb31-258 The Contribution Fo Nebraska Farm Women To Family Income Through Poultry And Dairy Products, M. Ruth Clark

University of Nebraska-Lincoln Extension: Historical Materials

This investigation was made in 1929-1930 for the purpose of studying the activities of Nebraska farm women in the raising of poultry and in the care of dairy products, to discover whether or not such activities resulted in a contribution to the family income. With this in view, a group of women were asked to keep records for one year (from April 1, 1929 to March 31, 1930) of the value and amount of dairy and poultry products sold or used, of all expense incurred in production, and of the time spent both by the homemaker herself and by all …
