Development Process


Incoming heifers receive the following vaccinations:

  • Vista®  Once SQ  (5way with Pasturella)
  • 7-way
  • Somnus
  • Safe Guard
  • Back pour

During Bangs vaccinating, the heifers then receive:

  • Express 5 FPVL5

At the time of Reproductive Tract Scoring (RTS), the heifers are poured for lice.

Reproductive Tract Scoring (RTS) is done 4-6 weeks prior to the first breeding period.  Dr. Jay Hudson uses ultrasound technology to rectally palpate the uterine horns and ovaries for breeding maturity.  He determines the size and tone of the uterus along with follicular activity to determine a RTS for each heifer with a number from 5 (cycling) to 1(immature).  These scores place the heifers in the appropriate group for optimal breeding.

  • Score 5 – a score 4 heifer, that has actively cycled. (These heifers are usually bred 3-5 weeks after RTS.)
  • Score 4 – good uterine tone and size, follicles are present, getting ready to cycle. (These heifers are usually bred 6-8 weeks after RTS to allow for optimal development.)
  • Score 3 – some uterine tone and development in size, some follicles, close to cycling. (These heifers usually are bred 9-11 weeks after RTS to allow the heifer to further develop.)
  • Score 2 – some uterine development, no uterine tone, no cycling yet. (About half of these heifers are culled.)
  • Score 1 – small uterus and ovaries, no uterine activity or tone. (These heifers are culled.)


At the time of synchronization, the heifers also receive:




The heifers are put on a 49 mega cal diet targeting a 1.5 – 2# ADG.  When the target weight is achieved, the heifers then move to a maintenance diet.  Energy is increased before breeding and through breeding to insure nutritional needs are being met.
