Introduction Our group has been working with Floyd Cattle Company. Leeann Floyd
is our contact in the organization. We began the report process by making an outline of every group
member’s responsibility. Each group member was assigned a specific section of the report.
The report covers the scientific background of artificial insemination and embryo transferring.
Floyd Cattle Company currently outsources these processes. The report covers the benefits of doing these processes in house by building there own facility.
For the report itself, Jimmy was responsible for interaction with Leeann. Meredith, Nathan, and I were responsible for doing outside research to provide an outline of the benefits.
We all combined our work for the actual report, and did group editing. We decided to format the document as simply as possible. Floyd
Cattle Company is a very busy establishment and seem as if they just want the facts with nothing fancy.
Current Situation Travel to San Marcos Limited number of cows to be
processed Little control over the process Stress on the cows
Proposed Course of Action Facilities
• Covered Chute• Small Shed for Lab• Lab Equipment• Large Pens (as stress free as possible)
Personnel• Jared Floyd
AI and Beef Cows Less that 5% of the national beef cow
herd is inseminated artificially• Cattle are kept in range environments• Requires extensive labor and management
skills to detect estrous
How do we minimize time and labor?...
Timed Insemination or “Mass Mating”
Method used in Estrous Synchronization • Eliminates estrus detection from business model
More predictable time of service• Detection does not affect time of service• Cost savings
The Estrous Cycle
POLYESTROUS--Female Bovine• Experience Estrous cycle throughout the
year
Day 0 First Stage “The Estrous Stage”• Peak estrogen levels• Ovulation occurs approximately 10-12
hours after onset of estrous• Increased activity
The Estrous Cycle (cont.)
Day 2-3 Second Stage “Metestrus Stage”• Releases Progesterone - pregnancy maintaining hormone
DAY 6-17 Third Stage “Diestrus Stage”• Longest stage• Results in a fully functional corpus luteum
Day 18-21 Last Stage “Proestrus”• Declining progesterone levels• Start to develop high estrogen levels• Initiated the next estrogen cycle.
Estrous Synchronization Manipulation of the Estrous Cycle
• Induce estrous in order to bring a group of females into estrus at a predetermined time
• Reduces time and labor spent on heat detection
• More easily facilitate breeding• Essential to an effective AI program
Prostaglandin Prostaglandin
• naturally occurring hormone• Essential to the normal regulation of the
animal’s reproductive cycle • Intramuscular injection• One or Two- Injection system
Prostaglandin (cont.) One-Injection System
• Administer injection on day 6 (Diestrus stage)
• Days 7-11 heat detection & breeding
Two-Injection System• Separate injections 10-12 days apart• All cattle are injected during the proestrus
stage• Observe over the next five days
Prostaglandin Plus May administer in conjunction with
other protocols
PROGESTERONEESTROGEN
Internal Benefits Produce ten or more calves each year
from their best cows, instead of one Increase sale of quality genetics Extend productive life of older cows Option to sell unused embryos Ability to oversee entire process
External Benefits Serve other cattle producers in the
area• Newman Show Cattle- Stanton, TX• Chisum Club Calves- Springlake, TX• Day Show Cattle- Meadow, TX• T Knox Herefords- Stanton, TX
*Just a few that currently also outsource their ET and AI to San Marcos.
Conclusion We completed our report well ahead of schedule
so we were able to edit very closely. Everyone in the group was very cooperative and
we got most of our assigned tasks done in a timely manner.
The approach we took to writing this report proved to be effective. Everything ran smoothly in our brainstorming, researching, and writing processes.
We wrote our report so that very realistic benefits could result from it. We are very hopeful that this report actually influences Floyd Cattle Company’s decision on building an embryo transfer facility.
