Remember it can only put in one doe that why the price is cheaper. I think Curt got bout 85% conception but wasnt 100% buck fawns

Using fresh semen begs that followup question, is fresh semen more successful tht non- fresh and should we make a definite distinction when discussing the pros and cons of using sexed semen into two categories, Fresh sexed semen and Non- fresh sexed. Lets keep this post going because I think we are now starting to gather enough info to start building a case for pro or con.

Coldspring, thanks for the followup, with limited sample size of the fresh sexed semen versus the non- fresh sexed semen we will have to be patient for more results. I would be greatly surprised if the statistical difference between the two would be that little( 10%). I would be willing to wager that the fresh sexed semen would be much more effective in conception that the non- fresh. With that being said, we will just have to wait for more deerfarmers to come forward with legitmate results.
I took 8 does to Curts to be AIed to fresh sexed semen here were my results:
7 out of 8 stuck to AI
1 gave me twin does
1 gave me triplet bucks
2 gave me twin bucks
3 gave me single bucks, two of those were first time mothers
Hope this helps

I tried posting my results twice (with colorful commentary) and got kicked back both times. I'll retry again later. Sorry.
In dairy cows they *** semen to 75% or 95% I was just wondering if they do the same for the whitetails. The 75% is way less but our theory on the 75% stuff we might as well get the conventional straws. Maybe that is why some of u are getting doe fawns to idn. Out of hundred of *** staws in the cattle we have only had two not be what they were suppose to be with the 95% straws.
I was told that it is 96% male semen in the male straws, I just wish I could take those kind of odds to the powerball. Just my luck

Here are the results from my sexed semen AI. These numbers include the previous figures Matt K posted.
We Lap AI’d 24 does to fresh male sexed semen.
22 does stuck
45 total fawns born (this includes 2 stillborn)
4 doe fawns, 41 bucks.
Comes out to about 92% conception and 91% accuracy, with just over 2 fawns/doe using fresh sexed semen. The 91% accuracy is taking into account that one doe at Matt’s place had twin doe fawns. That is a statistical anomaly, to say the least. Either that or Matt K doesn’t know a doe from a buck fawn. I wont even go into his track record on that! lol My conventional semen (frozen) results were about 82% with approximately 2.3 fawns per doe, also doing Lap AI.
I sold some frozen sexed semen to a couple farms. In a nutshell, they got around 60-65% conception. Their conception rate was about 10% or so lower than their conventional semen AI. (Sexed and conventional semen AI was done Lap) It is important to take into account the difference in success with sexed and conventional AI. If you get 40% success with sexed, but only 50% with conventional semen, is it fair to say that the sexed semen results were awful? Maybe yes, but so was the conventional AI. The problem probably isn’t the sexed semen, but the AI program in general. Also with the frozen sexed, they did experience less fawns per doe than conventional. Both farms stated that they did a higher percentage of yearling does with sexed semen, so that may explain not only a lower conception rate, but also possibly, fewer fawns per doe. Another important point is to compare what your conventional AI numbers are versus sexed, in fawns/doe, both in adults and in yearlings. There are many factors to consider when looking at success in sexed semen. Ask the right questions and then consider if using sexed semen is right for your program.
At the end of the day, I think the results from my farms were phenomenal. I would have been happy if rates were a little lower. In the future, I can see doing more does on the farm with fresh sexed, except I’ll target specifically for bucks AND does. I simply want to take the guesswork out of what I will be tagging when I walk up to a couple newborn fawns.
If anyone wants to discuss any of this further, don’t hesitate to call me.

P.S. I do believe there are more farms using sexed semen than they will admit to. I suppose everything has to be a big damn secret with some people. They probably never heard the saying that “individually we’ll do nothing, but together we can do anything”.

This is what my understanding is of the sorting process for sexed semen. The entire process of collecting and sorting is tough on semen. That is why it is more common to have collections NOT be good enough to even send through the sorting process. It is imperative to START with a good amount of healthy semen. Small collections, and those collections that may be somewhat compromised in quality, usually don't have good results when sorting. Often, they can tell you prior to sorting the collection if it is even worth attempting to sort or not. Also, they try to get the highest percentage accuracy in all the sexed straws. Some bucks will sort more accurate than others. My experience is that they usually are somewhere between 90-96% accurate. When the sorting is done, the lab can tell you what the accuracy rate is on the sexed straws.
Don't take this info to the bank, but it is my understanding.

Curt, this ia great firsthand info, thank you so much for your response. Now, how does a deerfarmer get fresh sexed semen as opposed to frozen sexed semen. Secondly, has anyone tried inseminating sexed semen cervically, maybe even using more that one straw per doe?

Thanks for being open and honest Curt! Its a quality that is lacking in the upper tier of deer farmers today.-Jason
