G93-1148 Common Infectious Diseases That Cause Abortions In Cattle, Duane N. Rice, Douglas Rogers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide briefly discusses the common infectious diseases that cause abortions in cattle. "Abortion" is the expulsion of the fetus prior to the end of the normal gestation period. Many abortions occur very early after conception and the embryos or fetuses are so small that they may not be seen. Other abortions may occur near normal calving time and it is difficult to determine whether the cow has aborted or whether a premature birth has occurred. Abortions have many causes which may include physiological problems (such as hormonal imbalances), metabolic problems, toxicoses and/or infectious diseases caused by protozoa, bacteria or …

G93-1168 Moisture Testing Of Grain, Hay And Silage, Bruce Anderson, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide offers methods to help producers test moisture content of grain, hay, silage and other feeds.

Knowing the moisture and dry matter (DM) content of feeds is important to farmers for several reasons:

1. Livestock performance depends on DM consumed; thus, DM content must be known to accurately formulate rations.

2. Knowledge of moisture content is needed for harvest decisions during haying and silage chopping and for safe storage of grains, hay, and silage.

3. Moisture content is a major factor related to the value, or price, of forages and grain.

Every producer should be able to test for …

G93-1184 Bovine Ocular Neoplasia, L. J. Perino, D. D. Griffin, D. G. Rogers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide will aid in the early identification and proper management of bovine ocular neoplasia, commonly known as cancer eye, including appropriate veterniary care. The common name for bovine ocular neoplasia, also known as ocular squamous cell tumors, is cancer eye. The term cancer eye is not entirely accurate and carries negative connotations. As we will explain in this NebGuide not all of these growths are cancerous. The scientific term for a cow is "bovine," the medical term for the eye is "ocular," and the medical term for these new and abnormal growths is "neoplasia." Thus, the term bovine ocular …

G93-1172 Starting Cattle, Dicky D. Griffin, Louis Perino, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide gives guidelines to help feedlot operators prepare and establish a plan for starting new cattle on feed that minimizes stress, reduces morbidity (sickness) and improves performance.

An animal's first few weeks in a feedlot can influence performance throughout the entire feeding period. The cattle are adapting to a new environment and may be exposed to disease, some for the first time. It is vitally important to prevent and deal with health problems at this time to prevent loss of performance.

Cattle entering the feedlot encounter a range of problems that arise from several sources, including health and nutritional …

G93-1138 Water Quality And Requirements For Dairy Cattle, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide stresses the importance to the dairy cow of water, an essential but often overlooked nutrient.

Providing insufficient water or water of poor quality to dairy cattle can limit milk production and growth, and can cause health problems. An adequate supply of clean water promotes normal rumen function, high feed intake, digestion and nutrient absorption. Water also maintains blood volume, supplies tissue needs, and makes up about 87 percent of the milk secreted by the cow. The following sections discuss water intake and requirements, water quality and guidelines for proper use of cattle waterers.

G93-1143 How To Use The National Genetic Evaluations For Somatic Cell Scores, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide will help dairy producers use information from the National Genetic Evaluations for Somatic Cell Scores in selecting sires.

New genetic evaluations for Somatic Cell Scores (SCS) will be published in July 1993. This evaluation system will allow producers, for the first time, to select sires genetically for SCS. This system will use national data and will be analyzed by USDA, Beltsville, MD. The procedures used will be exactly the same as the current evaluation system for milk, fat and protein.
