    • Avoiding Calving Problems 
      Sprott, L. R. (1998-03-12)
      Calving difficulty, or dystocia, is influenced largely by genetics and the age of the dam. The main cause of calving problems is heavy birthweight. Solutions include selecting the right bull and mating it to properly ...
    • Avoiding Calving Problems. 
      Sprott, L. R.; Sides, Gary E. (Texas Agricultural Extension Service, 1987)
    • Body Condition, Nutrition & Reproduction of Beef Cows 
      Herd, Dennis B.; Sprott, L. R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      A BCS of 5 or more (at least 14 percent body fat) at calving and through breeding is required for good reproductive performance. Over-stocking pastures is a common cause of poor body condition and reproductive failure. ...
    • Body Condition, Nutrition and Reproduction of Beef Cows 
      Herd, Dennis B.; Sprott, L. R. (1998-03-16)
      Producers must be able to evaluate beef cows' body reserves and to relate the evaluation to reproductive and nutritional management. Topics discussed include the practical importance of body condition scoring and various ...
    • Body Fat in Beef Cows Affects Pregnancy Rates 
      Sprott, L. R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Pregnancy rates are highly variable in beef herds and are influenced by many factors including nutrition. Low pregnancy rates are caused by improper nutrition in 90 or more cases.
    • Body Fat in Beef Cows Affects Pregnancy Rates. 
      Sprott, L. R. (Texas Agricultural Extension Service, 1986)
    • Break-even Costs for Cow/Calf Producers 
      Sprott, L. R. (1998-10-14)
      Calculating the break-even costs of production can help cow/calf producers make better management decisions for the current year or for the near future. This publication explains how to figure break-even costs.
    • Breeding Soundness of Bulls 
      Sprott, L. R.; Thrift, Todd A.; Carpenter, Bruce B. (1998-10-09)
      The breeding ability and genetic makeup of the bull are critical to any breeding program. This leaflet explains the function of each organ in the bull's reproductive system, the evaluation of a bull's breeding soundness, ...
    • Bull Management for Cow/Calf Producers 
      Sprott, L. R.; Carpenter, Bruce B.; Thrift, Todd A. (2005-09-09)
      Management techniques can help ensure that bulls contribute their fullest production potential and improve the chances of high fertility. Proper bull selection and management from weaning through maturity will boost their ...
    • Bull Management for Cow/Calf Producers 
      Sprott, L. R.; Carpenter, Bruce; Thrift, Todd (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      It is often said that a bull contributes half the production in a calf crop. This may be true for an average bull, but probably exaggerates contributions from a poor quality bull and dramatically underestimates those from ...
    • Calf Removal - A Way to Stimulate Reproduction in Cows 
      Sprott, L. R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Cows that are slow to breed or fail to breed are costly and reduce herd productivity and profitability. Many factors affect a cow's ability to breed after calving. Assuming that reproductive diseases are not prevalent in ...
    • Calf Removal: A Way to Stimulate Reproduction in Cows 
      Sprott, L. R. (2003-10-08)
      Cows that are slow to breed or fail to breed are costly to producers. One of the factors that delays the resumption of estrous activity in a cow--and subsequent breeding--is nursing stress. Removing a calf from a dam, ...
    • Choosing the Time of Year to Breed and Calve Beef Cows in Texas 
      Sprott, L. R. (2001-01-04)
      The time of year that cows calve directly affects many herd management practices. Therefore, producers should consider carefully the time of year to breed cattle. This publication looks at research that covers several ...
    • Cow/Calf Production Record Software. 
      Cowley, Jerry; Sprott, L. R.; Carpenter, Bruce B.; Clary, Greg; Comforth, Gerald C.; Johnson, Jeff; Paschal, Joe; Hammack, Steve; Stokes, Ken; Pena, Joe; Amosson, Steve; Adams, Nelson; Beavers, Stan (Texas Agricultural Extension Service, 1991)
    • Determining Pregnancy in Cattle 
      Beverly, John R.; Sprott, L. R.; Carpenter, Bruce B. (2008-12-16)
      The process of palpating to determine pregnancy in cattle and the equipment used during palpation are described and illustrated in this bulletin. The female reproductive system is discussed, along with the developmental ...

      Moore, Frederick Thomas (Texas A&M University, 2005-08-29)
      These studies were conducted on several central Texas agricultural producers?? properties, the Stiles Farm Foundation, the Texas Agricultural Experiment Station, and the Texas A&M University campus. First, an experimental ...
    • Fenprostalene-induced luteal regression in the beef cow : histological and ultrastructural characterization 
      Betts, James Gordon (Texas A&M University. Libraries, 1987)
      Brahman-cross cows (day 11 or 12 of the estrous cycle) were used to study the effects of prostaglandin-induced luteolysis on the corpus luteum (CL). Four cows (0 h controls) were injected (sc) with saline while 16 cows ...
