G77-358 Artesian (Confinsed) Aquifers And Effect Of Pumping, Darryll T. Pederson, Deon D. Axthelm Jan 1977

G77-358 Artesian (Confinsed) Aquifers And Effect Of Pumping, Darryll T. Pederson, Deon D. Axthelm

University of Nebraska-Lincoln Extension: Historical Materials

Nebraskans are concerned about declining water levels in some domestic and stock wells.

Nebraskans are concerned about declining water levels in some domestic and stock wells. Drought and irrigation well development have been major factors. Water level declines have been especially pronounced during the pumping season in places where the aquifer is artesian or confined (a confined aquifer is also referred to as an artesian aquifer). Many domestic and livestock pumps may have to be set deeper in order to yield water. In nearly all cases water levels recover rapidly when the pumping season ends. Large water-level fluctuations are normal …


G77-336 Coccidiosis Of Cattle, Donald L. Ferguson Jan 1977

G77-336 Coccidiosis Of Cattle, Donald L. Ferguson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide contains information on the identification, treatment, and prevention of coccidiosis in cattle.

Coccidiosis continues to be one of the major disease problems for cattle producers. It is caused by microscopic, one-celled parasites, chiefly of the genus Eimeria. Twenty-one species of Eimeria have been reported in cattle. Only two, Eimeria bovis and Eimeria zuernii, are regularly associated with clinical infections in the field.


G77-364 Mycoplasmal Pneumonia And Other Mycoplasmal Diseases Of Swine, Alex Hogg, William P. Switzer, Daniel O. Farrington Jan 1977

G77-364 Mycoplasmal Pneumonia And Other Mycoplasmal Diseases Of Swine, Alex Hogg, William P. Switzer, Daniel O. Farrington

University of Nebraska-Lincoln Extension: Historical Materials

Swine producers are often confused by the complexity of the mycoplasmal infections; this fact sheet is an attempt to clarify the information that is currently available about these swine diseases.

Swine producers are often confused by the complexity of the mycoplasmal infections. This fact sheet is an attempt to clarify the information that is currently available about these swine diseases. There are three recognized Mycoplasma spp. of bacteria that cause disease in pigs--Mycoplasma hyopneumoniae, Mycoplasma hyorhinis and Mycoplasma hyosynoviae.


G77-372 Water Requirements For Beef Cattle, Paul Q. Guyer Jan 1977

G77-372 Water Requirements For Beef Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Water requirements of cattle are influenced by a number of physiological and environmental conditions. These include such things as the rate and composition of gain, pregnancy, lactation, physical activity, type of ration, salt and dry matter intake, and environmental temperature.

The minimum requirement of cattle for water is a reflection of that needed for body growth, for fetal growth or lactation, and of that lost by excretion in the urine, feces, or sweat or by evaporation from the lungs or skin. Anything influencing these needs or losses will influence the minimum requirement.


G77-384 Common Milkweed (Revised July 1984), Alex Martin, O.C. Burnside Jan 1977

G77-384 Common Milkweed (Revised July 1984), Alex Martin, O.C. Burnside

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses milkweed and how to control it in farmland.

Common milkweed (Asclepias syriaca L.) is a perennial, broadleaf weed native to North America. It is most common in eastern and central Nebraska, but is occasionally found farther west in moist sites.


G77-331 Sampling Feeds For Analyses, Bruce Anderson, Terry L. Mader, Rick Grant Jan 1977

G77-331 Sampling Feeds For Analyses, Bruce Anderson, Terry L. Mader, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

Sampling is the key to accurate feed analyses and properly balancing livestock rations. Here's how to do it.

Accurate feed analyses are needed to balance livestock rations, correctly price hay, formulate least cost supplements, and efficiently allocate homegrown feeds to the proper class of livestock. Sampling is the most important factor affecting accuracy of feed analyses.

The feed value of most forages varies. Therefore, test forages routinely to determine their best and most economical use. With adequate forage testing, you can develop an accurate forage inventory which allows you to efficiently allocate higher quality forage to high-producing livestock and poorer …


G77-344 Annual Flowers For Specific Uses In Nebraska, Dale T. Lindgren Jan 1977

G77-344 Annual Flowers For Specific Uses In Nebraska, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

Wondering what annual flowers to plant where? This NebGuide can help.

Annual flowers grow from seed, come into flower and die in a single growing season. The following lists of annual flowers are grouped for specific uses in Nebraska. Common names are listed first, followed by scientific names.


G77-386 Wheat In Poultry Rations, T.W. Sullivan, E.W. Gleaves Jan 1977

G77-386 Wheat In Poultry Rations, T.W. Sullivan, E.W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This publication examines the advantages and disadvantages of wheat as a component of poultry feed.

Wheat is usually considered a source of human food rather than an ingredient for poultry and livestock feeds. This is especially true in the United States, where corn, milo and other feed grains are abundantly produced. In recent years one of every two bushels of wheat produced in the United States has been exported. If world production and supplies of wheat are high, a surplus develops and wheat prices are lowered. When this situation occurs wheat becomes an attractive alternative to corn or milo in …


G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach Jan 1977

G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.

Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.


G77-360 Balancing Corn Silage Dairy Rations, Foster G. Owen Jan 1977

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.


G77-371 Nebraska Livestock Market Outlets, Allen Wellman Jan 1977
