Benefits of Estrus Synchronization and Artificial Insemination

Mark Z. Johnson, Oklahoma State University Extension Beef Cattle Breeding Specialist

 

Regardless of when your calving season occurs, manipulating the reproductive process of your cow herd can result in shorter breeding and calving seasons.  Accordingly, more calves born earlier in the calving season result in an older, heavier, more uniform calf crop when you wean.  Shortened calving seasons permit improvements in herd health and management such as timing of vaccinations and practices that add to calf value with less labor requirements (or at the very least concentrating labor efforts into a shorter time frame).  Cows that are closer to the same stage of gestation can also be fed and grouped accordingly which facilitates a higher level of management.

 

Estrus synchronization can be used for natural mating or breeding by Artificial Insemination (AI). Synchronization protocols permit us to concentrate the labor needed for heat detection to a few days, and in some cases eliminate the need for heat detection when cows can be bred on a timed basis.  Choosing an estrous synchronization protocol which can be used with AI or natural mating can be difficult as a number of synchronization methods are available.  Traditional protocols are designed to mimic or control the corpus luteum on the ovary.  Newer protocols have been designed to control ovulation and/or the follicular waves that occur on the ovary during the 21-day estrous cycle.  Estrus synchronization systems vary in cost, labor required, and effectiveness.  Management decisions regarding synchronization should be based on answers to the following questions:

 

1.) Do you have adequate labor and facilities to successfully implement the management practices involved?  Most synchronization protocols will require at least two trips through the chute, plus at least one more if breeding by AI.  Heat detection will require labor for several hours, twice a day to observe standing heats.  Labor will be required to sort cows.


2.) Do you have an AI technician available for the duration of time you will be AI breeding cows?

3.) Cost of synchronization protocols can vary significantly. Is the cost justified? Whatever method you determine best fits your operation, be sure to use the correct synchronization product at the recommended time and follow Beef Quality Assurance practices when administering the product.  


4.) Have you identified an AI sire(s) offering the genetic potential to increase your profit potential relative to your intended marketing endpoint or use of calves sired?

 

Use of AI permits us to get more cows bred to genetically superior sires for traits of economic importance to our operation's production and marketing goals.  Synchronization at the onset of breeding season, results in more cows having heats in the first 18 - 25 days of breeding season.  Female's return heats will remain synchronized to a degree, which gives a second chance to AI each female in the early part of breeding season.  Without any synchronization, herd managers are faced with a 21 days of continual estrus detection and typically only one opportunity for AI in most females.

 

Bottom Line: estrus synchronization can be an important management tool to get cows settled as early in the breeding season as possible and get cows bred to bulls with highest possible genetic value.  A defined breeding season is important to permit meaningful record keeping, timely management and profit potential.  Maintaining a 60-to-75-day breeding and calving season can be one of the most important management tools for cow calf producers.

Sustainable Poultry Production

July 12, 2024
Hamburg, NY

Join us to learn about sustainable poultry! Cornell Extension poultry specialist Amy Barkley will guide us in selecting the right breeds, establishing ecologically beneficial production, troubleshooting pests & diseases, and processing. We will tour a 5A-certified on-farm processing center and watch a demonstration. Everyone who identifies as a woman in agriculture is welcome to this free learning circle. Lunch is provided, so please register in advance! This event will allow participants to connect with fellow land stewards and producers and support everyone in learning together. We will discuss full-circle sustainable poultry production, from breed selection, housing, pests & diseases to processing and marketing. REGISTER

Led by Cornell Cooperative Extension poultry specialist Amy Barkley and farmer Kate Geiger; facilitated by American Farmland Trust NY's Women for the Land Program Associate, Caitlin Tucker, CCA.
