G95-1244 Ventilation Fans: Efficiency And Maintenance, David P. Shelton, Gerald R. Bodman
G95-1244 Ventilation Fans: Efficiency And Maintenance, David P. Shelton, Gerald R. Bodman
University of Nebraska-Lincoln Extension: Historical Materials
This publication describes efficiency and design factors to consider when selecting a ventilation fan. Basic maintenance procedures needed for efficient operation are also discussed.
An energy efficient ventilation system requires good design and good equipment. Selecting efficient ventilation fans and keeping them in good working condition will keep operating costs down.
G95-1243 Ventilation Fans: Types And Sizes, Gerald R. Bodman, David P. Shelton
G95-1243 Ventilation Fans: Types And Sizes, Gerald R. Bodman, David P. Shelton
University of Nebraska-Lincoln Extension: Historical Materials
This publication describes the most common types of ventilation fans and compares their physical and performance characteristics.
Two general types of ventilation fans are commonly used for agricultural applications. Each type has many different blade diameters, materials, blade shapes, speeds, and motor horsepowers available. The desired airflow rate and the resistance to airflow through the ventilation system, or static pressure capabilities, are the two primary considerations when selecting a ventilation fan. Other considerations include maintenance requirements, noise levels, and energy efficiency.

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:
1. new Mature Equivalent Factors,
2. adjustments incorporated for days open,
3. and the genetic base year changed to 1990.
Let's discuss each change and look at how these changes will effect the 1995 proofs.
