Make note of the details

Most engineers are proud of the DeLaval VMS and how it works. They would be eager to tell what they know and what you can do to improve your workflow. What they don’t always know is what you don’t know. For example, a farmer could think that milk cups do not connect properly by a few, or more, cows is normal, or sounds that you now find normal but that are not. If the farmer doesn’t make note of the details, then the technician would have to coincidentally experience the issue in order to solve it.

So, make sure to always have your phone or a pen and notebook with you. Make a list of things for the technician to take a look at and they’ll let you know if anything is out of the ordinary. Having the possibility to take notes would also make your work easier. If you think of something while you’re standing behind your barn or in the middle of the field, you could just jot it down and make note of it.

Making more effective use of activity measurement.

You know that the best time to inseminate cows is usually between 60 – 90 days after the calving date.
That is the time that the cow has likely been immersed in negative energy for a while. This means she gives already a few month more milk than the amount of energy that she can absorb from the feed she receives.
This also means that the cow does not always clearly show that she is in heat. Sometimes, this means that the cow does not always achieve 1+ 2 ++ and 3 +++.
And this doesn’t get any better during hot summer days either …

Most cows only show their heat for 4 – 7 hours and often also at night. During this time, you are not all the time in the stable, but the activity meter is.
Thus, it is very important that the system displays correct measurements. For this it is important to know that the transponders are good – (there’s a checklist in DelPro for that) – that they’re not too loose or tight around the neck – (place a flat hand between neck and collar ) – and that the antenna is not too close to the cow recognition place, such as the VMS, selection gate, or too close to electric motors, thick walls, solar panels, cables, etc.

Since DelPro version 5.2, a “Worklist Activity” is available in which the latest knowledge of possibilities is applied using smart filters.
Through these filters, you can also find those cows that have too little activity for a +.

In this list, cows in heat are categorized as: too early for insemination, correct insemination moment or a return. It then churns out a proposal for the right insemination moment!
Lastly, the category “too little activity” you find the cow who is not fit.
This information worklist results in advice about what you can do with the cow.

Users rate this list very positively, which proves that it adds value to the system!

Ask your technician or DeLaval DelPro Advisor for this “Worklist Activity” list!

Flies transfer bacteria: How do you keep the place clean?

Most causative agents of udder inflammation can be divided into cow-bound bacteria and environment-related bacteria.

Bacteria related to the environment, such as the common Uberis Streptococci, is often spread through beds that are unclean.
Or uncleaned areas, such as those near or under water troughs, cow brushes, fences, etc. This dirt is taken back into the cubicles. The cow will lie down in it and spread it further.
Or Milk equipment / cluster  is not clean enough between milkings so could also play a role.

Cow-bound bacteria such as Staphylococci Aureus and Streptococci Agalaction spread from cow to cow or from milk to cow. So milk leakers, wet cubicles, and uncleaned milk utensils should be cleaned properly on the outside and the inside, since spreading could begin there.

But these cow-bound bacteria can also be passed on by flies!

And they are always in every puddle of milk….

Tackle fly control consequently in time. This is also very important for udder health.

And are you already grazing or are you planning to graze?

Do you have a good replacement?

Do you have a manual for when you’re suddenly unavailable? Is there someone who knows enough about your farm and your cows? Is there someone to replace your job around the VMS, the calves or feeding practices?

In the meantime, trainees at agricultural schools and agri-business farm care services in the Netherlands are learning about the possibilities to replace a farmer with an automatic milking system. It’s even possible to complete exams in these courses!

In general, it is smart to be a proponent of these initiatives. More important, it could prove incredibly useful for when you yourselves are suddenly unavailable.

Feeding concentrate at “Peak Yield”

From the version DelPro 5.2 it is possible to use a feeding table at “Peak Yield”.

The concentrate feed for cows up to about 100 Days In Milk (DIM) is often a point of solid discussion:
Do we use an invariable feeding table or not?

These cows must be given the opportunity to give a lot of milk, even though they could temporarily decrease production. Of course, these cows require a lot of energy, (concentrated) feed.

But many advisers and veterinarians observe that during this period some cows who aren’t very comfortable and do not give a lot of milk in general, they are worse off with too much of concentrated feed.

Since DelPro 5.2 there is the possibility to operate at Peak Yield.

This is a nice system for feeding cows after the start-up period, for example up to 40 DIM, and then from about 40 days to 100 DIM go feeding on Peak Yield table.

Then the cows that give a lot of milk get the food that is due to them, but cows that for some reason give too little milk, for example: she has calved too soon, then she will only grow from much concentrate, which is too expensive and gives often problems later on.
Or she has problems with her rumen or claws and therefore too little roughage intake, and therefore she never gets (for longer time) high production. That cow should get less – for her – rumen acidic concentrate feed.

If a cow that gives a lot of milk still temporarily decreases in production, she will continue to keep the concentrate that belongs to the highest production she has given as a 7-day average during this period.

So the concentrate feed amount remains stable.

After 100 days in milk, the negative energy balance period should be depleted. If the cow gives less milk, then you should also decrease the concentrate.

So then the advice is: just feed on “Milk Yield” table.

It is still important to check feed deliveries via a clear list once a week.
