How to, go from all year calving to jan-feb calving

If you don't want to sell any cows the simplest way is to shave month/months off each year.

From the sounds of it you want everything dry in December and start calving say 10th January?

Don't serve anything between January 1st and March 31st and automatically you won't have any calves between October and December which means over Christmas no calves to feed so will reduce your work load quite quickly

Then every year from there shave another 1-3 months depending on what your comfortable with, either by culling or milking them round

Calve all heifers in during when you want your block to be and from now ONLY serve to dairy semen when you want your block to be (ie if you want to be block calving January-march you want all your heifer replacements born in January and ideally February but certainly no later than march) don't have heifers being born in August because they'll be calving in at the wrong age again or still Ayr

Thats kinda the way im thinking and in around 3 years i should be near there

@daveydiesel1 if you have bigger type cows at the moment even your barren price would easily cover the cost of buying in Spring crossbreds. I just bought 10 at Exeter (8 heifers, 2 cows) calving in March for average 720 a head and they are bang on what we want.

Was there any change on litres produced once you got completely into the block calving system compared to ayr?
Yeah litres went down BUT along with change to block calving I also sold the mixer wagon to concentrate on milk from grazed grass, reduced in parlour meal and more jex cows came through.

A lot of change from 2014 to 2017 but am very with where the business is now.

Im not planning to decrease meal, just hoping to maximise potential milk from grass

Tbh i never worked it out what im getting atm, i know id like some more. Calving ranges ftom yearly to mabe 15-16 months
I know this makes me sound like a tw*t but it sounds like you need to tighten up on what you are doing at the minute, know your numbers and figure out what you want out of a change, other than a holiday at dry time (cows still need feeding though)
If you've a small number of cows on AYR and they're getting away from you a bit with fertility, how are you going to cope when the herd is treated as one? You might start Jan/Feb calving and end up Apr/May pretty quick.

If cows don't go out until mid-April, isn't January calving a bit early to make the most of grass?

Im trying to sort out the problems i already have, this is 1 of the ways im thinking of doing it by having certain times of the year more focused on breeding/ calve rearing etc instead of it being ayr and then things slip through the net as busy at other times. As for time of year the idea is get them calved and feed the best silage as can keep it for that time then, get a few good months milk, then out to grass to get more good months 🤞and by the time the grass quality starts to drop and back into house where the milk normally drops off a fair bit the cows will be reaching the latter end of lactation any way. Have a time of drying off the cows say over a month-6weeks and keep a tighter eye on cows being dried off at correct times instead of again some slipping through resulting in not having a long enough dry period. Get the foot man in and do all dry cows so starting off lactation on mostly cows with no sore feet. Batch drying will suit for any vaccinations that need done as most comes in batch bottles and doesnt suit 1 cow dried this week 2 next week etc. Have a more focused calve rearing time where cleanliness can be kept to a better standard as your not rushing away to work at grass or barley etc. Mabe i come across as a total numpty but these are some of the positives iv been thinking about, certainly theres negatives aswel, but im all ears to others opinions and open to advice as per me starting a thread on here asking about it

Not criticising, you know more about the job than I do, just asking questions really.
Thinking back to when I worked on dairy farms, I think I'd have preferred 80 cows spread out over the year rather than all at once, as the odd mistake wouldn't have such a big impact.
I can see who running the cows as one seems good though.
 
When dad converted from AYR pedigree to spring calving in 98 he just stopped serving cows and turned them out, unfortunately you’re a bit late to make the decision now. Would of been better to stop serving in July 23 just gone and then start late April 24, I’d have the vet on standby to pre mate check and make sure there ready to serve, yes you’ll lose milk this year but the first loss is the easiest

Would recommend the same. Modern dairy cows can milk on through for a year and a half easily without too much loss in yield and when you consider the increase in fat and protein it's probably even less. I sold my autumn calvers and bought in spring calving heifers but only bought in problems. Hindsight I should have calved my autumn calvers, milked them through, and started AI'ing everything come April/May. If your planning on drying everything off you have to be ruthless in culling cows and cut of dates for AI'ing.
