Advantages of Artificial Insemination
Disadvantages of Artificial Insemination
- AI provides the opportunity to use bulls of superior genetic producing ability. Most of the beef bulls in AI Studs have been performance tested and additional information on the progeny's performance is available.
- AI can reduce the threat of veneral disease and lessen the possibility of delayed conception caused by sterile sires.
- AI permits the use of more than one bull in breeding programs. The problem of rotating bulls and maintaining separate breeding pastures is minimized by using AI.
- It is generally less expensive to use AI than to purchase and keep a top quality bull throughout the year.
- The individual cow and herd records will identify the sire and breeding date which will allow a better evaluation of sire performance and a prediction of calving dates.
Guidelines for a Successful AI Program
- An AI program requires more time and skill, especially in the initial phases of the program.
- Cow identification, handling facilities and breeding pastures must be available.
- Heat detection should be carried out twice per day on the breeding herd.
- The level of herd management and nutrition is more critical in an AI program than in a natural service program.
- Plan your breeding program well in advance.
- Identify all cows and keep reproduction records on the herd.
- Make sure the cow herd has adequate levels of nutrition both before and after calving.
- Heat detect twice each day.
- Obtain AI technician services and bull semen from a reputable insemination business.
- Develop good handling facilities.
