and he probably went visiting for a good reason ;-) Wait 10 days and give all the heifers a shot of prostaglandin.

Seperate placentas DOES NOT mean that a heifer will be safe from being a freemartin if her twin was a bull.

I was wanting to see the feed and body condition in the pictures!

Pregnancy would certainly stop them cycling - so this needs to be ruled out regardless of where you think the bull was!!!! Other option would include anoestrus due to feed/body condition reasons (though you sound like this is not a problem). Another factor could be the feed they are on - very...

can you post some pictures?

If the calf has navel ill and is walking stiffly (sore in the joints) then I would probably write it off too. I've seen lots of similar calves - you can't patch them up for a while with antibiotics etc but generally if the bacteria have been in the bloodstream and gone to the joints you can...

You need to wait at least seven days after she last cycled before Lutalyse will "short cycle her". She should come into heat 2-4 days after the jab!

your AI techs must be different to ours then - ours aren't repro specialists, they AI only (whatever the farmer puts in front of them), they aren't allowed to use drugs, and do not palpate the whole of the repro tract as I do for a CIDR/repro exam. The first heat is less fertile - and an...

Here is a link to the drug companys official website. It clearly states that when uterine involution is normal a CIDR can be used 21 days after calving !!! (I didn't just dream it up!). I am a cattle veterinarian in a pastoral based dairy area. We calve every 12 months to fit in with...

Depends on the cow - if her uterus is fully involuted then I have used them as early as 3-4 weeks post calving.

What caused the abortion? There are other diseases that cause abortion (you only mentioned lepto and vibrio vaccinations) - don't know about you location but we see neospora, BVD, listeria, mouldy feeds, nitrate poisoning etc all causing abortions To get an answer you need to do some testing...

She produces a little over 50 pounds of milk per day. We got her as a nurse cow hence the 4 calves. They barely keep her nursed down. Have you seen her cycling?

The ones that did not show signs of heat after the first shot are probably those that cycled within the week prior to the Lutalyse jab (cows will only respond to PG a week after ovulating and not within this time) - if you consider the maths then I would expect in a random group of cows (that...

If she had a cycle during the week before her Lutalyse she will not have responded to it. I usually recommend the second Lutalyse shot 10 days after the first one (this gives her time to have a cycle and be receptive again to the lutalyse - in case you missed it!) Remember though that of she...

There are numerous option - depends what you want to do. AI to detected heat or fixed time AI???

I have done a caesarian on a 14 month old Jersey heifer - the calf was full term... If faced with this situation you have a couple of options 1) abort early with prostaglandins 2) let them go to full term but be ready with expert assistance available nearby and a high chance of a caesarian 3)...

It could also be a "chicken or egg" scenario - did she not nurse because something was wrong with her from birth, or, is she like she is because she didn't get colostrum. Either way if it has been like this from birth then it is less likely that it is something you can fix - that's my general...

I will eat my boots if they can tell how far along she is by a blood test!!!

Has anyone done an internal repro exam on her ? That would certainly be on my "must do" list for a post calving problem. Milk fever??? In a heifer - on this side of the world that is as rare as hens teeth (never see it). You'd have to be doing something pretty weird to be getting primary...
