    • Anaplasmosis in Beef Cattle 
      Gill, Ronald J. (1994-09-29)
      Anaplasmosis is an infectious disease of cattle that destroys red blood cells. The disease is caused by a parasite, Anaplasma marginale, found in the red blood cells of infected cattle. It can be transmitted from infected ...
    • Anaplasmosis In Beef Cattle 
      Gill, Ronald J. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      naplasmosis is an infectious disease of cattle that causes destruction of red blood cells. The disease is caused by a minute parasite, Anaplasma marginale , found in the red blood cells of infected cattle. It can be ...
    • Biosecurity for Beef Cattle Operations 
      Cleere, Jason; Gill, Ronald J.; Dement, Angela (2008-10-06)
      Biosecurity in the beef cattle industry involves understanding disease transmission and animal immunity, and then establishing a sound program for disease prevention. This publication explains general biosecurity practices.
    • Bovine Paratuberculosis of Beef Cattle 
      Faries Jr., Floron C.; Roussel, Allen J.; Thrift, Todd A.; Gill, Ronald J.; Magee, Derry D. (2002-02-05)
      Paratuberculosis, or Johne's (pronounced "Yo-nees) disease, is a chronic intestinal infection of cattle. It is increasingly recognized in both dairy and beef herds. This publication discusses transmission of the bacteria ...
    • Bovine Paratuberculosis of Beef Cattle: A wasting condition, commonly called Johne's disease 
      Faries, Floron C., Jr.; Roussel, Allen J.; Thrift, Todd R.; Gill, Ronald J.; Magee, Derry D. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
    • Factors and Feeds for Supplementing Beef Cattle 
      Hammack, Stephen; Gill, Ronald J.; Machen, Rick (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
    • Factors and Feeds for Supplementing Beef Cows 
      Hammack, Stephen P.; Gill, Ronald J. (2000-05-03)
      A beef cow requires energy, protein, minerals and vitamins in its diet. Many factors, including forage quantity and quality and animal body condition, affect the amounts of required nutrients.
    • Nutrient Composition of Feeds. 
      Gill, Ronald J.; Herd, Dennis B. (Texas Agricultural Experiment Station, 1986)
    • Nutrient Requirements of Beef Cattle. 
      Gill, Ronald J.; Herd, Dennis B. (Texas Agricultural Extension Service, 1987)
    • Postpartum reproductive performance of mares fed varying levels of protein 
      Gill, Ronald J. (Texas A&M University. Libraries, 1984)
      Thirty mares were fed varying levels of protein during the last 90 days of gestation and the first 90 days of the subsequent lactation to determine the effect of protein intake on mare postpartum reproductive performance, ...
    • Texas Adapted Genetic Strategies for Beef Cattle III: Body Size and Milking Level 
      Hammack, Stephen P.; Gill, Ronald J. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Body size or mass and milking level are primary genetic traits in beef production. In addition to their direct effects size and milk relate to many other production functions.
    • Texas Adapted Genetic Strategies for Beef Cattle X: Frame Score, Frame Size, and Weight 
      Hammack, Stephen P.; Gill, Ronald J. (2009-04-02)
      Body size is an important genetic factor in beef cattle production. Size is most accurately estimated by considering several factors, such as weight, skeletal size and body condition. Frame Scores are a way of estimating ...
    • Texas Adapted Genetic Strategies for Beef Cattle X: Frame Score, Frame Size, and Weight 
      Hammack, Stephen P.; Gill, Ronald J. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Body size is an important genetic factor in beef cattle production. Historically, size was first estimated by measurements such as height or length. As scales were developed, weight became more common as a measure of size. ...
    • Texas Adapted Genetic Strategies for Beef Cattle--03: Body Size and Milking Level 
      Hammack, Stephen P.; Gill, Ronald J. (2009-03-30)
      Body size and milking potential are important genetic traits in beef production. Wide ranges of body size can be efficient, depending on production environments, breeding systems and carcass specification. Biological ...
