Embryo Transfer Program
The Preparation (Step 2)

With the actual flush date set and on the horizon, we spent several days making our final preparations…getting the does ready.

In January we made the decision to definitely use Kattie as our donor doe instead of Venus. Venus may be used in our next flush if this one is successful. We removed Kattie's male kid in mid-January but left Samantha for Kattie to wean. In retrospect this may have been a mistake; we probably should have weaned Samantha when we removed Thunderbolt.

On January 24th we picked up the last two does we need for receips. Damon Deese, the manager of the Lawrence County Co-Op, is loaning us two of his does. In return we will allow him to breed his remaining does to one of our bucks and return the two does bred. Since he does not have a buck, we determined we would give him a buck kid from the ET breeding. Damon, in loaning us the does, is just being a good neighbor.

Arrangements were confirmed with Jeff Latham of the Lazy L Farm in Livingston, AL. We were told CIDRs were to go in on March 1st; the breed date would be March 18th; and the flush would take place on March 25th. Since the breed date conflicted with the goat show in Montgomery, AL, we cancelled our plans to attend the show.

Jeff recommended we start to increase the amount of feed for the donor and receips a month to six weeks before the flush. Before we could increase the feed, we felt we needed to wean the babies of Kattie, our donor, and seven of the eleven receips so these does could dry up. Samantha was almost 4 months old; time to wean her regardless of how much Kattie protested. Dot, Matilda, Xenia, Koko, and Louise had all kidded in November, so their kids were at least 10 weeks old when we weaned them. Faith's daughter, Gidget, was only 8 weeks old as was Koko's little boy; but both kids were eating well. So the kids went in one paddock and the mothers in another, and we had a lot of extremely unhappy goats for about two weeks. (The mothers more unhappy than the babies because not only were they uncomfortable with full udders, they also were confident we were starving them by feeding only hay and water!)

We got a call from Jeff early the morning of February 24th. The flush date had moved up to March 20th, so the breed date was advanced to March 13th and CIDRs had to go in on February 26th. Mild panic!

Seven of the receips and Kattie were not fully dried off, and we had to immediately start increasing their feed to 4 pounds a day. Ken called Dr. Galbraith's, and he had medication to dry up the does – 1cc of Forsomide for 3 days. The 8 got their first shots on the 24th.

On February 25th, the 8 does got their second shot to dry off; and all 12 does were given 2cc vitamin AD&E plus 2cc BoSe. All 12 were also given weight-appropriate doses of Ivomec Plus, and they all got pedicures.

Also on the 25th, Jeff shipped us 14 CIDRs and Folltropin®–V along with written instructions for us to follow.

On the afternoon of February 26th, UPS delivered our supplies. The "tails" of all the CIDRs were painted with bright red fingernail polish, and the ball-like tips were cut off. (The tips were cut off to prevent other does from pulling out the CIDRs. The white strings were painted red so we could see them and insure they remain where they belong.)

 
CIDR

That task accomplished, off to the barn to insert CIDRs.

CIDRs are intravaginal progesterone release devices for controlled breeding of goats and sheep. Each CIDR contains .3 grams of progesterone. Besides being used in embryo transfer programs, they are frequently used in “out of season” breeding of some breeds because they control the oestrous cycle. When used with goats the instructions say to insert the device for 17 to 19 days.

There are 7 steps in the insertion directions. Be sure to wear rubber gloves.

  1. Wash the applicator in an antiseptic solution. Dip the front of the applicator into an obstetrical lubricant.
  2. Place the CIDR into the applicator so the wings are folded and only the tips of the wings protrude from the top of the applicator.
  3. Put some of the KY-Jelly on the end of the applicator.
  4. Lift the tail of the animal and wipe clean the lips of the vulva with a disposable tissue.
  5. With the animal’s tail lifted, insert the loaded applicator, sloping it slightly upwards, through the vulva and into the forward portion of the vagina.
  6. Grasp the finger holds of the applicator and firmly pull the barrel of the applicator toward the handle to remove.
  7. If the device is correctly in place, the wings will open in the anterior of the vagina and the tail of the CIDR is visibly protruding from the vulva.

 
The CIDRs we used were EAZI-BREED™ by Pharmacia & Upjohn out of Mt. Wellington, Auckland.

The CIDRs actually went in a lot easier than we were anticipating. By the last one we had it down to a short routine. The 8 does also got their final shot to dry off.

With the goats, donor and receips, once again being fed full rations (2 pounds of feed each – twice a day) and the preliminary preparations completed, we're ready for the next step.
