Artificial insemination in goats can aid in conserving endangered breeds, but it comes with complications and uncertain outcomes.

Artificial insemination (AI) has been around for hundreds of years, with the first known animal birth resulting from AI taking place in the late 1700s — a dog gave birth to three puppies from the process. In the late 1800s, studies in Russia led to huge advancements in AI as a means of reproduction in a number of species, most notably in horses. Interest in artificial insemination migrated to Japan in the early 1900s, where it was used with livestock and poultry. Around the same time, Danish farmers used AI to improve the conception rates of dairy cattle, which drastically changed the dairy industry into what we have today.

Modern Day

Currently, artificial insemination is commonly used with horses, pigs, and cattle — allowing for pregnancy by a desired sire at a specific time. Production turkey breeds are unable to reproduce without the use of AI, making it a vital part of the modern poultry industry. These advancements allow for cheaper, more accessible protein supplies worldwide.

In most species, AI is done transcervically. This means inserting the semen sample into the uterus by way of the cervix — a much less invasive method of introducing sperm to the animal in question than laparoscopy. In goats, however, getting through the cervix can be difficult, and the success rates for pregnancy can be as low as 50%. Additionally, the pipette used to deposit the semen into the doe’s uterus can cause damage to the cervix or uterus, resulting in fertility issues — a risk some breeders may be unwilling to take.

Laparoscopic Insemination

Because of these issues, laparoscopic insemination is more commonly practiced with goats. While the average success rate is higher — estimated to be around 70 to 90% — some breeds, such as the Arapawa, are more susceptible to miscarriage. The success of the procedure can be affected by the health of the buck, the quality of the semen sample, the storage facility, and even the speed at which the sample is thawed before application. Studies have shown that frozen goat semen results in far lower fertility than fresh samples.

Laparoscopic insemination is performed by making two small incisions(one for the laparoscope, one for the pipette) with a needle, and the semen is deposited. The scope and pipette are removed, the incisions closed, and then the goat recovers.

However, finding a veterinary surgeon who specializes in laparoscopic surgery on goats can be difficult. According to Tufts Veterinary School, only they and one other practice do this kind of procedure in the northeastern United States. With the shortage of vets in many parts of the United States, finding a buck, a storage facility capable of handling the samples, and an available surgeon, and timing the surgery for when a doe is in heat may feel like a daunting task for the average homesteader.

Worries don’t end after the surgery is complete, either, due to the chance of infection that comes with any surgery. Some breeders may not want to risk the loss of a valuable breeding doe for the uncertain hope of progeny.

Use in Conservation

For those interested in conserving endangered heritage breeds, artificial insemination can be a valuable tool to save critical genetics. AI enables breeders to produce more valuable young without the cost of maintaining multiple males on the property year-round. It reduces transportation costs when new genetics are needed and allows for the selection of the best sires. All of these are important considerations for breeders interested in saving endangered goat breeds, especially those with smaller farms or homesteads.

In goat breeds with a population that’s limited or spread out over large distances, AI — combined with careful coordination of breeding efforts — can make the difference between restoration and extinction. The San Clemente Island Goat Breeders Association and the Arapawa Goat Breeders Association, along with others, are working toward developing semen storage and artificial insemination programs to help save critically endangered breeds and protect individual genetic lines.

One Arapawa breeder, Emily Pennington, has used AI to breed her does over the past two years, resulting in the birth of more than 15 kids, with about an 80% success rate. The medical costs for her kidding season were $550 for shipping semen, plus $640 to impregnate seven does. $1,200 might seem like a large investment. However, it resulted in 10 kids — a valuable addition for a breed with only around 600 specimens left worldwide. $120 for an endangered, healthy baby is a great payoff!

Problems with AI

Between them, the Livestock Conservancy in America and the Rare Breed Survival Trust in Europe recognize 10 goat breeds in need of conservation efforts. In Indonesia, preservation of Gembrong goats is a concern. So why is artificial insemination not used more frequently in the effort to save these endangered breeds?

Primarily because Emily’s 80% success rate is an outlier. In the case of the Philadelphia Zoo, the use of artificial insemination on three goats resulted in only one pregnancy, although the successful doe had twins. The cost of keeping semen, medical care, and other expenses can make breeders — especially on small homesteads — nervous about the outcome.

Obstacles to Overcome

With only around 600 Arapawa goats, 100 Old English Goats, and as few as 50 Gembrong goats in the world, it’s apparent that drastic steps need to be taken if breeds like these are to be protected. Artificial insemination practices for goats require more research to increase their viability; practitioners need to compare notes on their practices, and breeders need to organize to guarantee the best genetic matches. Once these obstacles are overcome, AI can be an even more valuable tool for goat conservationists.
