Yield crash

[Foregoneconclusion]

Hi.

This time last week the cows were on an upward trajectory towards a 30kg average at 0 19 kg/ cake / litre fed in parlour. The ration outside was balanced 3 forages n prot pellet. 2 Kgs.


Since Sunday the yld has fallen very quickly to 24kg.

Exactly the same ration. Mixed and fed automatically at same times and quantities so nothing has changed.

There was a bit more feed left over on Sunday into Monday than on Friday..( normally little poss 150 kg ) there was perhaps 250.

Exactly the same parlour cake fed in the 3 robots.

Rumination and eating times have barely altered according to the affi collars.. No cows have shown digestive disruptions.

Visits and milking frequency remain high at 3.4 milkings a day..

I have checked feeder calibration, milk meter calibration. Water is fine..

No mastitis, no illness in the shed atall..

What have I missed.
I have never seen anything like this..

I was chuffed that the cows were milking so well. And wallop.

Do you vaccinate for IBR? Is the tanker milk line down as well as the computer?

winter dysentery?

 

[Barmyfarmer]

Winter dysentery has hit my cows hard since the weekend and milks plummeted collars picking up health alerts as rumination stops

 

[HasthorpeGrange]

Starlings?

 

[lazy farmer]

Mycotoxins?
Or a mild bug that will be gone as soon as it arrived ?

 

[som farmer]

cow covid ! or swine flu .........

just like us, plenty of winter bugs about, we pick them up, so they will pick them up, just the same.

Weather ?? - temperatures this week noticeably lower, back to normal next week - if the Met office are corrrect - see if it corrects ?

No digestive upsets, collar data not showing any changes

Weather didnt really change until Moinday/ Tues, by then they were dropping quickly. We normally see an increased feed demand but rarely a drop in yld of any size.

It's not inconceivable but cows don't look like they are ailing from anything. Activity, feed rumination, muck etc all good.

It is possible there's been a lump of crappy silage gone into the bunkers.. but presumably the cows will show rumination or other symptoms ? Anyone got experience of mycotoxin overtloading>?

Muck is steady..

not definitely. Our silages have come back as very high in mycotxins. My understanding is it creates penecilin in the rumen thus killing off all the good bacteria. They still ruminate ( I believe) but can’t utilise.

silage analysis came back today, 15.3% protein, 11 me.
latest milk 4.84 fat, 3.7 protein.
ration working out 19.6% pro, on paper, to high. Swapping straight soya to soya/rape, cut urea back, and see.

on the other hand, cows are looking great, dung correct, and bulling like mad.

calved a lot of xbred hfrs, more cows are working up now, milk rising nicely, so perhaps the really monkey bred hfrs are letting the side down a bit.

our crimped wheat was showing a bit 'mouldy' as we started feeding it, so added mycotoxin in, didn't make any difference, and stopped now we are into the crimp 'properly', no mould.

Starlings?

Was just wondering that,they turned up here a few days ago

The scouting ones were here a few days ago, nothing for them here this year.

New load of concentrate on Friday?

How long did you feed toxin binder? I always feed it at a low rate as an insurance policy, if I thought there was a risk for whatever reason i increase the rate.

kept it in for about 3 weeks, only did it because a bit of mould at the front of the crimp clamp, soon went.
