    • Avoiding Calving Problems 
      Sprott, L.R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Beef heifers experience calving difficulty, or dystocia, more frequently than do mature cows. Dystocia is characterized by prolonged or difficult labor due to heavy birthweight and/or small pelvic area of the dam. Death ...
    • Body Condition, Nutrition and Reproduction of Beef Cows. 
      Herd, Dennis B.; Sprott, L.R. (Texas Agricultural Experiment Station, 1986)
    • Break-even Costs for Cow/Calf Producers 
      Sprott, L.R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      CALCULATING BREAK-EVEN COSTS of production can help cow/calf producers make better management decisions for the current year or for the near future.
    • Breeding Soundness of Bulls 
      Sprott, L.R.; Thrift, T.A.; Carpenter, B.B. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      The importance of the bull in a cattle breeding program often is underestimated. A cow is responsible for half the genetic material in only one calf each year, while the bull is responsible for half the genetic material ...
    • Choosing the Time of Year to Breed and Calve Beef Cows in Texas 
      Sprott, L.R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      As any cattleman knows, the time of year when cows calve directly affects many herd management practices: • The start of calving is dictated by the start of breeding. • Cows calving in the fall normally need more ...
    • Differential effects of norgestomet on the bovine hypothalamus and pituitary in regulating secretion of gonadotropins 
      Fanning, Michael David (Texas A&M University. Libraries, 1994)
      Bilateral (BOVX) and unilateral ovariectomized (UOVX) beef heifers were utilized to ascertain whether the inhibitory effect of a progestin (norgestomet, NOR) on LH secretion is mediated via both the hypothalamus and the ...
    • Effects of conventional or low bull to female ratio and utilization of reproductive tract scores in extensively-managed, natural mating breeding groups 
      Rathmann, Ryan James (Texas A&M University, 2007-04-25)
      The current study involved two experiments which were conducted at the Texas A&M Agricultural Research and Extension Center in Uvalde (semi-arid environment) from 2002 to 2004. In experiment one, Bonsmara bulls (n = 19; ...
    • Infectious Bovine Rhinotracheitis 
      Sprott, L.R.; Wikse, Steve (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
    • Management of Replacement Heifers for a High Reproductive and Calving Rate 
      Sprott, L.R.; Wikse, Steve (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      A profitable beef operation involves producing the maximum pounds of beef at the least possible cost. Profitability is primarily dependent on reproductive performance, which is best measured by percent calf crop. "Percent ...
    • Raising Replacement Heifers on Winter Pastures on the Texas Gulf Coast 
      Sprott, L.R.; Bade, David (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Raising replacement heifers on winter pastures can be successful provided that plants are well established and receive adequate rainfall. Weight gains of 1.0 to 2.0 lbs per head per day are common. The problem is that lack ...
    • Reproductive Diseases in Cattle 
      Sprott, L.R.; Field, Robert W. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
    • Reproductive Performance in Replacement Heifers Has Long-Term Consequences on the Cow Herd 
      Sprott, L.R. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Everyone wants good cows! These are females that wean a calf annually throughout their lifetime. A cow’s ability to do this depends heavily on her performance as a heifer. Thus, good heifers, make for good cows. There ...
    • Synchronizing Estrus in Cattle 
      Sprott, L.R.; Carpenter, B.B. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
      Estrus synchronization—which is a manipulation of the reproductive process—offers several benefits. It: Reduces and in some cases eliminates the need to detect estrus and allows the herd manager to schedule breeding ...
    • The Value and Use of Internal Pelvic Area Measurements in Beef Cattle 
      Sprott, L.R.; Carpenter, B.B. (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
