Across breed EPD tables released by MARC
Updated: 06/14/2013 The table of adjustment factors to be used to estimate across-breed expected progeny differences (AB-EPDs) for 18 breeds was released at the Beef Improvement Federation Annual Meeting in Oklahoma City, OK (Table 1). Across-breed adjustment factors have been calculated for growth traits and maternal milk since 1993. Adjustment factors for carcass traits have been calculated since 2009; to be included, breeds must have carcass data in the U.S. Meat Animal Research Center (USMARC) database and report their carcass EPDs on an actual carcass basis using an age-adjusted endpoint.
Managing Moldy Corn
The generally cool, wet growing season across the Corn Belt in 2009 contributed to a higher than normal incidence of ear molds in corn. The severity of the problem depends on variations in weather, crop genetics, and field management practices. As a result, some Indiana counties report few problems while others face serious management issues. Where mold levels in corn are high, they can shorten corn storage life, reduce the marketability of grain, and (when in feed) affect livestock health and performance.Read More
Beef Management Practices When Forages are in Short Supply
When environmental conditions are less than ideal, forage production will be reduced. The most common cause of low forage yield is less than average rainfall in the late spring and summer
which is often accompanied by high environmental temperatures. Harsh winter conditions or
early spring freezes can also result in less than optimum forage supplies.
Resources for Managing or Assessing Drought-Stressed Field Crops
Severe drought stress does not typically afflict Indiana agriculture every year. The amount and pattern of normal annual precipitation throughout the state usually satisfy the moisture needs of its major agronomic crops of corn, soybean, wheat, and hay. From time to time, however, severe droughts or extended periods of insufficient rainfall occur and cause major yield losses. The 2012 cropping season is currently positioning itself to join the ranks of the "great" droughts.
Utilizing Drought-Damaged Corn
This publication discusses identification of drought stress and its effect on corn growth and yield, possible revenue sources if you are affected by drought, utilizing drought-stressed corn, switching to another crop, and reducing the risk of drought stress.
Dangers of Silo Gasses
After harvested forages are placed in a silo, they often produce gases during the early stages of the fermentation process.
Aspergillus Ear Rot
The fungus Aspergillus flavus causes Aspergillus ear rot, one of the most important diseases in corn. The fungus produces a mycotoxin — known as aflatoxin — inside the diseased corn kernels.
Considering Your Grazing, Haying, and Silage Options for Herbicide-treated Corn and Soybean
University of Missouri
With the drought we are currently experiencing in Missouri and throughout much of the Midwest, many farmers are starting to consider using at least some portion of their corn and soybean crop for livestock feeding purposes.
Ammoniation of Low-quality Roughages
North Dakota State University
When good or medium quality hay is not available, livestock producers may consider feeding ammoniated low quality hays or crop residues. Ammoniation can double or triple crude protein levels in crop residues such as straw and corn stalks and increase digestibility 10 to 30 percent, making them equivalent to prairie hay in feed value.Read More
Beef Cattle Management Strategies During a Drought
West Virginia University
Periods of drought requires beef producers to make some adjustments in their production program or sell livestock. When cattle are sold out of desperation, the producer loses. If you have not begun to make contingency plans, start now.
What's Your Goal for This Winter?
University of Kentucky
The current feed shortage has stimulated a lot of "panic buying" of low quality feeds and producers are baling anything that will roll up.
