Goat ART Update

On October 13, 2010, Caprine Genetics held an Assisted Reproductive Technologies Field Day at the farm in Petersburg, VA. The Field Day program consisted of a laparoscopic artificial insemination (Lap AI) program with ten (10) does, a frozen embryo transfer (ET) protocol with two does, and a trans-cervical artificial insemination (AI) training program for all participants. All program participants had the opportunity to participate in the surgical prep of the does for the procedures and assist in the surgical suite with the actual procedures. At the end of the session Dr. Burroughs conducted an AI training session, allowing each participant hands-on training with trans-cervical AI procedures.

We have been very pleased with Dr. Burroughs and results of the ET and Lap AI programs of the past two years. From the 2010 Lap AI program, three of the ten does cycled back and were subsequently re-bred and are due in April 2011. Of the seven does that “caught”, we have kidded out 16 kids in three sets of triplets, three sets of twins and one single from a first timer. This is a kidding rate of 230 percent for the does that had kids and a rate of 160 percent for all ten (10) does. In our ET program this year, we used three frozen embryos remaining from our 2009 program resulting in two beautiful doelings. In addition, genetics from deceased bucks were used in some of the Lap AI does.

Although the total costs for the kids are higher than for natural goat reproduction, the option to use genetics from live or deceased bucks creates an opportunity to increase the herds’ genetic base and genetic quality. An additional benefit of the Lap AI and ET programs is the reduction in the lifecycle costs of owning a buck, in that there is no initial buck purchase and lifetime maintenance expenses, such as feed, segregated fencing, and veterinary expenses.

We at Carpine Genetics hope that our programs information and results will allow any serious breeder the data necessary to make an informed decision concerning the use of assisted reproductive technologies.
