What program is this please to achieve these results...... I have a plan for a busy August 19 which means I need a lot of heifers to calve within a few days of each other.

Our of curioisty what sort of numbers do you sinc and how spread would the calvings be from those serves?

The 5 day cidr program has plenty of research backing it for heifers. I’ve used it multiple times and had good results. There is another program that really doesn’t have info published and I don’t feel comfortable posting it online or reccomending it.

We had poor results with the standard cidir programs for heifers.

I’ve done groups of 90-100 on the one day. For heifers for us they will spread out over around 20 days. From 15 days early to 5 days over on 280 days gestation. We have bred hard for clalving ease so we seem to get them calving earlier these days.
 
Which sexed bull/bulls are you going to use?

Just Beaumont from Cogent. It's only a trial this year but my plan is to start a few days earlier than usual and do one week serving anything suitable to sexed jersey and others to conventional friesian and see how it goes. If it works then next year I'll go 100% sexed dairy and BB from day 1.

Much the same plan, but still starting services on the same day and hope to cut a week off the Ai for dairy and will do a week of blues until bulls go in, are you do sexed with R2's or just cows?

Just cows this year, I'll still be running bulls with heifers. Hopefully do 21 days if ai on them next year if I can figure out a way of handling and drafting them when they're down on our parkland.

Grant for mobile cattle yard(y), ours are in 3 groups 2k from the yards, year we did try to AI them had poor incalf rate as to much stress getting them in every day, but safer than a jersey bull:ROFLMAO:, how much did you pay for Beaumont or was it through south hams?

I spent last night looking at mobile cattle yard possibilities.

AI on heifers is still up for debate. On the cows, if I had 90% submission rate and AI 75% of those to sexed and the other 25% blue with only a 40% conception rate on the sexed that still gives 27 % in calf to sexed dairy. Allowing for the odd bull calf and odd one dying that should still give enough for a 20% replacement rate.

Also its IC heifers that I keep losing to Tb and they don't give you any more compensation if they're in calf to sexed.

If I'd read this thread earlier I wouldn't have bothered cidr syncing my autumn heifers with Sexcel. We probably achieved 20% to the first service .:(:mad:
 
We used cidr sync but then put scratch cards on and served based on the cards. I served just over 80% to 4M sexed and a few more that I was doubtful about to some Aberdeen angus. We then put the bulls in. PD results suggest we got 64% conception to sexed semen. We also got 92% of all the heifers in calf by 6 weeks.

we have used full sync programme on hfrs 65% 70% conception with normal straws, however we have been getting equally good results with a jab of oestrogen and scratches. fertility is probably increasing as we move further away from holstiens!
