Estrumate heifers.

jersey101

I know there's been plenty threads about this already but cant find what i want in any of them.
I have 8 heifers to put incalf for winter milk and i want to estrumate them and use sexed semen in them, but my father wont agree.
He has gotten the idea that if i use it this year ill always need to use it on them.
What can i say to convince him?

I bring it up every so often and tell him it will tighten up the autumn calving alot if we do it for just two years, and that if the sexed semen holds we will have 8 top class heifer calves with very high ebi's all in two weeks.
But still no go, any advice?
Thanks in advance

Using sexed semen on an estrumate heat more often than not is unsuccessful.

thought it worked very well on maiden heifers

if you want to synch heifers and use sexed semen, it's best to let the first heat after the estrumate pass and bull them in the next heat, conception rates are very poor with sexed semen on an estrumate induced heat

fella that does our scanning says never to use estrumate, their own heat will be a much better heat, and i am beginning to think he is right

Wouldn't use estrunate and sexed semen together even on maiden heifers.synchronosingbheifers works well for spring herds don't know about winter though.if heifers are all at or above correct weight why not just pick up naturally for say 10 days and then estrunate whatever hasn't been picked up.

tail painted 10 heifers yesterday, will ai for this week only on heat and then let aa bull in, 4 cows bulling this evening so will get them ai'd in the morning, they are their own heats

Well there all bulling hard every three weeks so maybe would best to leave them alone then. Will sexed semen hold on them do you think?

If they are bulling anyways defo don't bother injecting, only reason to inject is if they are poor at cycling (which you definitely don't need to be breeding a replacement heifer from), or case of if they are on an outfarm, and you want to get them all in heat over the space of say 10days instead of drawing it out over 3wks. Check up the history of the dam also on icbf, if the dam regularly needs 3 or more straws, I wouldnt be bothered using sexed on her daughter.

And if there is a reason you need to inject one, say one that doesn't come cycling, and your dad still won't agree, just injected her yourself on the sly and say nothing when she comes bulling

Yeh I know the feeling, but hopefully sexed will allow you to be far more selective, I've about 50cows calving between now and the end of March, I've identified 36 that are suitable for breeding, and I'll use sexed on them, and assuming most of them hold, I'll run the bull for any cow calving down after April. I've a decent few maiden heifers alongside that also. I know as things stand I can expand by 55cows post 2015, however unless I can get the cost of replacement heifers under control then I'll be at nothing. With aload of sexed straws early on, the aim is to have one big bunch of feb/march heifers who don't need a load of feeding to hit their target weights. Also by now, I'd rather buy in replacements at say 1200 calved down in feb, then have to spend say 1800 on myown out of season heifers, which will either cost more in feed to calf down for say 22months, or have to carry over to calf down at say 30months.

Progressive are supposed to have a really high solid/fert nz bull coming in in march he's supposed to be savage. Thinking of going the nz route on the cows

Why do you have to wait for him?
We just text our lad the cow number/bull code and he does the rest

Still no ABOs here! But loads of PBMs, smashing heifers! Whelan do you usually do as many cows this early (Aug calving), or are they carryovers? I'm scanning a good few cows and heifers tomorrow, I've afew late calvers, and smaller heifers who I spotted bulling over the last few months. Once I confirm they aren't in calf, but fine inside etc, I'll probably inject 1st Dec to calf down for Sept. I don't have too many autumn calvers this year at all, and will be culling afew of them anyways, and probably push the dec/jan ones around to late jan. But those few carryovers, alongside the late spring calvers should plenty fill my liquid contract.

Would you not consider diy ai whelan??.Im doing course next month for the very reason you were talking about above.My ai man might not arrive every day till 11 or 12 or maby later.Last thing you want with heifers /cows is waiting around the yard for hours,Think this stresses them a bit and could lead to repeats
