Allow me to explain myself. I have been using Golden Child for the last 3 years, never had to pull a calf, loved the power and growth I had with the calves and they were easy to work with. Last year before breeding season I purchased more semen(10 units) from the owners of the bull, before then I had been getting it through Genex. I had one straw left from the last year and went ahead and used it and the other 10 on some of my favorite cows, cows he had clicked with really well in the past. During calving season they came early and light and were pretty slick. I was quite suspicious but as they grew I knew they couldnt be GC calves. As far as conception goes it was ok, 8 calves out of the 10 units purchased from Lautners and my 1 for 1 out of the stuff from last year. I recently got the tests back.......the only one that was out of GC was the Genex collected semen. The sire of the others doesnt exist in the data bank. Before you ask I turned the cows out with a red clean up bull 10 days after breeding and got some black calves out of red cows. And no i did not mess up and forget to write the sire and cow down. Im quite disapointed about this.
