Early Events In Japanese Encephalitis Virus Infection: Viral Entry, Sang-Im Yun, Young-Min Lee Aug 2018

Early Events In Japanese Encephalitis Virus Infection: Viral Entry, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV), a mosquito-borne zoonotic flavivirus, is an enveloped positive-strand RNA virus that can cause a spectrum of clinical manifestations, ranging from mild febrile illness to severe neuroinvasive disease. Today, several killed and live vaccines are available in different parts of the globe for use in humans to prevent JEV-induced diseases, yet no antivirals are available to treat JEV-associated diseases. Despite the progress made in vaccine research and development, JEV is still a major public health problem in southern, eastern, and southeastern Asia, as well as northern Oceania, with the potential to become an emerging global pathogen.

An Accelerated Feeding Study For Dairy Beef Steers, D. R. Zobell Sep 2001

An Accelerated Feeding Study For Dairy Beef Steers, D. R. Zobell

All Archived Publications

A large number of Holstein bull (steer) calves are produced by the dairy industry. Producers who purchase these calves should understand that depending on the production strategy employed, the economic outcome could be quite broad. Dairy beef calves that are intensively managed, using aggressive feeding strategies to achieve high levels of efficiency, increase the opportunity for profitability.

Selection And Development Of Replacement Beef Heifers, Norris J. Stenquist, James A. Bennett Sep 1992

Selection And Development Of Replacement Beef Heifers, Norris J. Stenquist, James A. Bennett

Archived Agriculture Publications

Selection, development, management, and nutrition of heifer calves to be used as herd replacements are key factors in maintaining beef herd productivity. A cow/calf producer, to be successful, must have some goals or criterion for heifer selection and development. For practically all Utah cattle production areas, economics dictate that heifers must calve as two-year-olds. Heifers must be properly developed and managed to permit this. The following factors are important: Heifers should 1) become pregnant in the first 25 days of the breeding season, 2) give birth to a live calf with little or no calving difficulty, 3) raise a calf …

Growth Stimulants And Feed Additives, Norris J. Stenquist Feb 1990

Growth Stimulants And Feed Additives, Norris J. Stenquist

All Archived Publications

In recent years, the most revolutionary increases in beef cattle weights and feeding efficiencies have resulted from the development and use of growth stimulants, feed additives, and antibiotics. These nonnutritive products not only improve the rate and efficiency of gain but prevent certain diseases as well. Their use has significantly improved beef cattle production efficiency and provided a greater return per dollar invested than any other factor in the livestock industry. Growth stimulants deposit increased protein in the animal without changing protein or energy intake. They are designed to provide a constant slow release of active ingredients into the animal's …

Evaluating Growth And Maternal Traits Of Beef Cattle, Nyle J. Matthews Jan 1989

Evaluating Growth And Maternal Traits Of Beef Cattle, Nyle J. Matthews

Archived Agriculture Publications

For many years we evaluated cattle only on the basis of visual appraisal. Some people had a very good eye for cattle, but at best, eyeball evaluation was guess work. Many important traits, such as soundness, still require visual assessment.

Growth Stimulants, Nyle J. Matthews Jan 1989

Growth Stimulants, Nyle J. Matthews

Archived Agriculture Publications

A tiny pellet inserted under the skin of a calf's ear may increase weight gains as much as 15 to 20 percent. This same result would take years to accomplish through breeding and selection. These tiny pellets are growth stimulants. They are made of hormones that are constructed to slowly release minute amounts into the blood stream that stimulate the animal to produce natural body hormones. One of these hormones is a growth hormone. It regulates the rate of growth of the animal. Increasing the rate of growth will almost always improve feed efficiency and reduce maintenance costs. These pellets …

Selecting For Carcass Merit, Norris J. Stenquist Jan 1988

Selecting For Carcass Merit, Norris J. Stenquist

Archived Agriculture Publications

Today's consumers are asking for leaner, less-fatty beef. Much of the leaner beef now produced results from trimming excess fat before the product is sent to the consumer. For the future, the hope is to trim excess fat genetically by producing leaner, more heavily muscled beef cattle.
