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. …

G89-942 Can You Afford To Use Bovine Somatrophin (Bovine Growth Hormone)?, Jeffrey F. Keown
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
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 …
G89-989 How To Interpret The New Animal Model For Dairy Sire Evaluation, Jeffrey F. Keown
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 …
