If you are like me, then the sexed semen may not work. I am the perfect example of murphy's law when it comes to sexed semen. Since it is supposed to be 90+% accurate according to some; and others say 95%.... I decided that I would breed the one jersey I kept getting bull calves out of with the sexed semen for a heifer. Her very first calf was a heifer, drowned in the creek, then 3 bulls. So we bred her with the sexed semen.....bull #4 ...okay, next year, sexed semen bull #5, okay try again, next year, sexed semen, BULL # 6....I said just forget it, used regular semen and FINALLY GOT A LIVE HEIFER....It turned out to be her last calf as she aborted twice after that to regular semen and then got mastitis problems and her age was against her so she went. Am breeding her heifer now so will hope for a heifer, but I used regular semen.
That wasn't all, I had another 1/2 jersey/holstein that had 3 consecutive bull calves with sexed semen so finally used regular and got a bull then a heifer the next time...same bull used both years. It is kinda a joke that if I want a bull calf to use sexed semen. These 2 cows were both on dairies (different farms) and it wasn't me doing the breeding. But both of these farmers use sexed semen on their own cows to some degree and do get about 85-90 % heifers....

Now if I could get some sexed BULL semen to use on our beef cows since we have been running 75% heifer calves for the past 2 1/2 or 3 years........maybe I should try the "normal" sexed for female semen...with my luck I would get the 10% bull calf out of each straw.... HaHa

We do have one angus bull that does throw about 75% bull calves, but the others have been making up for it with heifers. This bull has been with us a long time and has always thrown predominantly bull calves all his life. Nice calves too....

I have one now.....just presented me with fifth or sixth bull even though we have had long talks while I scratch her back, about how nice it would be to have a pretty little heifer this time.....nother bull last week. I think I might even raise this one as a bull...he is pretty nice and growing well.

She's facing the wrong direction when she's bred.


I actually got to pondering over this and Contacted Dr. Bill Beal the Repro Specialist at Va Tech. asked him if there was anything I could do to change the outcome...

I decided to try it and looked up the select sires sexed semen bulls and ordered five units of

I have long thought that in cases like this, there is something in the cow that influences which gender gets through.

when i first started my own herd back in the mid 80's I bought three heifers. one of them had a bull every year and she paid the bills....sold almost every bull from her for a decent price. the other two had a normal mix of heifers and bulls....really wanted a heifer out of Betty but never got one...sold about a dozen bulls from her though...

Some bulls seem to throw sexed semen. I have one who has been over 75% bull calves for 3 straight years.

Soooo, theoretically, by increasing your bull battery on your herd. You'd get more bred at the beginning of their heat cycle, increasing the chances of having heifer calves.

That was the jest of my original post. I have always heard younger bulls are more aggressive breeders and will breed earlier in a cows cycle thus getting more heifers .

Coach

We have had a bull heavy calving year this season, 94% completed and 60% of them are bulls, we lost one over the weekend, it was the last heifer we had left to calve found her to late the calf had a leg turned back, Once they got the leg straightened out she had the calf on her own before they could get the chains on. We hope to have all of them on the ground by Thanksgiving.
