Using coil to bring cow into heat?

Siobhan1 · 25-01-2013 11:21PM #1

Hiya. My husband has a few cows that are not coming onto heat. He has heard of people using the coil but doesn't have a lot of info on it. Just wondering if anyone here has any experience of using the coil - good or bad - any info would be much appreciated.

A coil/cidr is quite useful to bring a cow into heat, but before using it i've a couple of questions here goes
1 suckler or dairy 2 how long calved 3 what condition are they in 4 what heat detection is used 5 slatted shed or other
alot of questions but they may be important.

1. Suckler
2. First calved heifer - oldest three month calved
3. Good condition - not in beef, doesed regularly with minerals
4. Patches
5. Slatted shed

Thanks

There is several trains of tought around this issue. some beef farmers will remove the calves and let them suckle twice a-day (this will bring on heat) and also provide an area maybe out-side the slatted shed part of a field or a lie back bedded with straw or chip to promote mounting. i'm not a beef farmer so others will have more knowledge on these and other ideas. From a dairying view i will use cidr's but always after scanning as this usually tells if the animals are cycling and are being missed or if they have no cl (corpus luteum) in this case they get a cidr ; a 10 day one at the start of breeding without PG prostaglandin or a 8 day one with PG given on day 7 in the later half of the breeding season.these are only used on problem breeders. while these work quite well conception will be alot lower in the case of the 10 day one maybe as low as 30%, with this in mind i would be slow to recommend this as a solution to your problem, i'd start with the first two suggestions and then a competant scanner/vet if there is still no heats.

I have used them a few times and would not use again, all cows repeated 3 times after use and one never kept,

1chippy · 26-01-2013 08:56PM

we used them a lot last year. some cows did repeat one batch of 5 repeated but 4 of them are in calving pens at the moment. waiting to calve 3 weeks to the day. all ready to go. scheduling is the main benefit i see. have another batch to go in tomorrow morn so will give you an update as it goes. we will be going with a seven day system on these ones. cidrs in day one estrumate day 6 remove cidrs day 7.

putting them in the easy bit, they do work. cows continually repeating should have nothing to do with the cidrs, these animals may already have been problem breeders or if the cidr is inserted too soon after calving.

Do you put them in yourself of get a vet to do it?

You remove Cidrs on day 7 - what day is she in standing heat?

Do you give her an ai straw on the day of standing heat or do you give her 2 straws - 1 on the day of standing heat + 1 the day after?

dont know what the issue was really, twas a few years ago, cows were 1 calf a year girls, just had gone late so had a brainwave to tighten them up

waited 30 days, inserted coils, left then in required period, removed, injected, cows came a bulling, AI them twice, they never kept,
sold 2 of them and kept the best one, let her run dry and she kept first time the following year

may or may not have been my fault all I know is it didnt work for me,

you would get very poor conception rates at 30 days but the fact they cycled after they should have improved at subsequent heats. how many more times were they served?
if they were your late calvers they generally have poorer fertility or may have became less fertile due to hard/traumatic calving.

Served twice first time and served two more times at 3 and 6 weeks,

funny man · 28-01-2013 10:36PM

I use a fair few of them here, fertility is a big problem so i would be lost with-out them. as a rule i won't cidr a cow unless she has gone past 42 days with-out coming into heat naturally. thats when the womb is ready and has returned to normal size.

standing day 9-10 and only gave 1 straw last year. will try the double straw this year, kinda as an experiment. can get expensive though.

are you sure you removed them on day 7?

1chippy · 28-01-2013 11:09PM

yeh, tried a few different time set ups last year all worked but some with better results than others. i put a good few in too early, at the 30-35 day mark which didnt get great results, but still pulled back my mean calving date. Giving all calved cows 1-1 1/2 kg of meal this year,they got boluses and bucket licks and starting to remove calves. have a real problem with the latest ones trying to pull them back in line. kinda working on the principle of see a good early calver in the mart take her home and sell the latest calver but not seeing a whole pile of quality going reasonably in the marts these days.
The vet is urging me to try a different method with the cidrs but its another few bob for him and an extra run through the crush. will try the latest i have to run as he says it has the best results.

No i never heard of taken the cidr out at day7 sounds very unusual. must check old treads here to see what other people do as very few other people here are commenting on this tread, maybe we are the only two ejits using them!. i learned that lesson too; not before 42 days but my vet is telling me 36 days now and if you use them before it you could fcuk up the cow for several cycles (which i don't believe that). what is the other method and what role does the vet play in the programme?
if your buying an early calver make sure she's a first or she could be a late calver that was let run.
