Artificial insemination (AI) Transferring semen to the reproductive tract of the doe.
AI is an excellent way to bring in superior genetics and proven bucks that can improve a herd quickly. It does require an initial investment of equipment but the genetic improvement is well worth the cost. We have utilized AI for several years with good results (66% success rate). This year (2020) we’ve been forced to use it for most of our does since we only have one buck and most of our does are closely related to him. This is the first year using NO hormones but instead allowing the goats to cycle naturally. Practice makes perfect and we are learning more and more but no where near perfect yet. Timing is everything! Knowing how long each doe’s estrus cycle is very important for success.
This is an empty ‘straw’ that holds 1/2 cc semen (approx 200 million sperm and, hopefully, has a greater than 30% motility)Microscope to check viability of the semen. A tiny speck of semen is placed on the slide so the condition of the sperm can be determined. Not all frozen semen is equal and it’s important to know the quality you’re working with.
Our liquid nitrogen tank and measuring stick. You can see the frost line showing the depth (cm) of No3 inside the specialized vacuum insulated tank. It holds approximately 35 liters of No3. And even though we have Select Sires come fill the tank on a regular schedule of every 3-4 months, we check the level weekly. Semen is expensive at $150-250 (or more) per 5 straws so its prudent to keep an regular check on the No3 level. This tank can hold up to 1,200 straws of semen at maximum capacity but I only have a few hundred straws stored at present. The liquid nitrogen keeps the semen alive and in suspended animation at a cool -320 deg F
