G96-1298 Milk Urea Nitrogen Testing, Rick J. Grant, Dennis Drudik, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to properly test for MUN and interpret the results.

Milk urea nitrogen (MUN) analyses can be used as a signal, or "red flag", to point out potential problems in your feeding program. In particular, high MUN values reflect excessive dietary crude protein or low rumen degradable nonfiber carbohydrates (NFC). The NFC fraction, usually composed of starch and other sugars, can be low when insufficient grain is fed, or grain is improperly processed. Appropriate MUN testing over a period of several months to fine tune a feeding management program can result in:

1. precisely meeting nutritional requirements, …

G94-1198 Switchgrass And Big Bluestem For Grazing And Hay, Robert B. Mitchell, Lowell E. Moser, Bruce Anderson, Steven S. Waller

University of Nebraska-Lincoln Extension: Historical Materials

The grazing management and cultural practices discussed in this NebGuide can make switchgrass and big bluestem high quality summer forage. Switchgrass and big bluestem are native warm-season grasses that can provide abundant, high-quality forage during summer. Switchgrass and big bluestem produce 70 to 80 percent of their growth after June 1 in Nebraska, while more than 75 percent of cool-season grass growth, such as bromegrass and bluegrass, occurs before June 1. Therefore, switchgrass and big bluestem can provide forage to graze after cool-season pastures have been utilized. However, switchgrass and big bluestem must be managed differently than cool-season grasses. Poor …

G94-1234 Should You Consider Expanding Your Dairy Herd?, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses both the benefits and possible drawbacks from expanding an existing dairy operation.

Nebraska's dairy industry is going through a transition. Producers are beginning to ask the question, "Should I expand, and if so, how large should my herd become?" Before considering this issue, the producer should first ask, "Do I really want to expand?" Expansion can be, and in many cases is, a traumatic experience, not only to the producer, but also to the producer's family. Every segment of the dairy enterprise should be consulted before making a decision. Call a family gathering and discuss this question …


G93-1180 Horn Fly Control On Cattle, John B. Campbell Jan 1993

G93-1180 Horn Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide identifies ways to control horn flies on cattle.

The horn fly is a blood-feeder that feeds 20 to 30 times per day. A population of several thousand horn flies may be present on one animal. When large numbers of these flies are on cattle, the cattle bunch and expend considerable effort fighting the flies. They will often stand in water or seek shade trying to get relief from the flies. When they do this, they fail to graze normally.

Studies in the United States and Canada show that during the grazing season yearling cattle free from horn flies …


G91-1032 Dairy Cow Health And Metabolic Disease Relative To Nutritional Factors, Duane N. Rice, Rick Stock Jan 1991

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 …

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 Jan 1986

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 Jan 1986

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.


G86-799 Health Management And Recommended Vaccinations For Dairy Replacements, Duane Rice, R. Gene White Jan 1986

G86-799 Health Management And Recommended Vaccinations For Dairy Replacements, Duane Rice, R. Gene White

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the importance of having a good vaccination schedule, and provides recommendations on which vaccinations to give, depending on variables. Correct management decisions are necessary to realize maximum returns on investments in any dairy operation. Dairymen sometimes assume there is a quick remedy for health problems, but the prevention of disease is by far less expensive. Preventing health problems in the dairy herd goes much further than using a veterinarian to treat individual animals with emergency problems. A veterinarian with experience and a genuine interest in dairy cattle is essential to assist the dairyman with herd health problems. …


G85-741 Estrous Synchronization For Beef Cattle, Gene H. Deutscher Jan 1985

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 …
