G83-655 Management Of Early Weaned Calves, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the benefits and disadvantages of weaning beef calves early, including rations and methods for both drylot and pasture-grain feeding programs.

Early weaning of beef calves is a management practice that should be considered under situations such as fall calving, drylot cow-calf production and drought. In areas where forage quality is very poor in late summer and early fall, early weaning might also be considered as a regular practice. Early weaning can enhance the efficiency of drylot cow-calf operations by allowing greater use of poor quality roughages by the cow herd.

A Survey Of Animal Behavior-Related Research And Teaching Activities In North American Agricultural And Veterinary Medical Colleges, W. R. Stricklin

Ethology Collection

A letter questionnaire was used to survey animal behavior-related research and teaching efforts in U.S.A. and Canadian university animal sciences departments (agriculture) and veterinary medical colleges. The objectives of the eleven questions of the survey were to identify behavior workers and to determine the current and planned levels of emphasis on research and teaching activities in domestic animal behavior. During 1981, questionnaires were mailed to 162 deans and chairmen, and 102 were answered and returned. Twenty-three persons were identified as having appointments specifically or primarily in animal behavior, and 99 persons were identified as having appointments that had some responsibilities …

G83-666 Breeding Soundness Examination Of Beef Bulls, James A. Gosey

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes factors to consider when evaluating a beef bull's reproductive ability. These include the reproductive tract, semen and mating desire. A herd bull that will settle a higher percentage of cows during a limited breeding season is essential to a successful cow-calf operation. In many cow-calf operations, however, the bull's role in the herd's reproductive performance is taken for granted. The bull's fertility is several times more important than that of a cow. Each bull can be expected to settle as many as 30 cows. The bull also contributes half of the genetic potential of the entire calf …

G83-678 Producing Milk With A Low Bacteria Count, Stanely E. Wallen, Don J. Kubik, Stephen L. James, Daniel J. Borer, Gerald R. Bodman, E. Denis Erickson, Duane N. Rice, Philip H. Cole, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides cleaning, sanitizing, mechanical, environmental and other procedures to follow to assure a low bacterial count in milk. Bacteria are tiny, rapidly reproducing microorganisms that are too small to be seen without a high power microscope. Their very tiny size makes it very difficult to eliminate them from dairy equipment. Because bacterial growth in milk may cause spoilage and possibly human illnesses, a low bacterial count is one of the best indicators of top quality milk. Milk will almost always be of top quality if properly harvested from healthy, clean cows with clean equipment, cooled quickly and kept …
