Cow Happy Lines: One Measure of Herd Health

The general health and well being of cows and dairy animals is something that we human overseers have to interpret through markers usually performed by tests of production, body scores, overall herd health trends, body language and herd interactions. The health of calves and calving problems and general crankiness of herd individuals when approached are also considerations.

As in all relationships, we gain a knowledge base that is built over time and can be referenced to determine those trends that are present.

However, as a dairy consultant walking on a farm for the first time, historical knowledge of the farm and its herd conditions are not readily available.  This same situation presents itself to a consumer attempting to secure a farm to consumer relationship for procurement of nutrient dense grassbased products.

Here then, are a few pointers to allow you to assess a farm’s potential product quality, aside from taste and eye appeal of the facility or its pretty eyed milk producers.  Being a cow man we will have to stay with cows in this reference because that’s what I know.

Farm “Curb” Appeal

When driving up to a place of purchase/farm a few things usually stand out for me. How many standing puddles are there for the cows to stand in, general curb appeal of the place, fence status as in it is up, straight and respected or have the inhabitants pushed it over or ignored it completely?

Do the cows look content and if in pasture can you see their ankles, or are they spitting stones to get grass and pushing each other around like a Black Friday Wii sale?

If the cows are in the loafing area in the midday heat or winter time cold, are they laying around with just a few standing, or are they all standing and stamping their feet?

One must understand what just happened to them or what are they getting ready to do.  Crowded up to milk does not count in this situation, but post milking, cows at midday should be lying around and 75% of the cows should be chewing their cud unless they have just been fed.

Cow Contentment or Agitation?

If cows are agitated, they are stressed and that has hundreds of possible reasons but we will not get into those today. I will only add the less breeze and hotter and crowded it is the more uncomfortable a milk cow will be. Think 8.5 months pregnant in mid August.  That’s a cow if air temp is over 86F degrees and humid with no breeze or there just isn’t enough space. I do not have relative knowledge, but I think I am writing to a majority of moms here.

Let’s Talk Manure!

Manure is another easy thing to judge given it is a frequent thing with milk cows, and if the manure does not shoot in a rainbow stream out onto a raised tail their diet is pretty good related to protein. Rainbow manure and manure on the rib cage means the cow is getting too much protein, and there is a direct correlation between tangy yogurt and manure on the ribs of cows.

Grassfed Cows:  Too Thin or Just Right?

While we are talking ribs of a cow, if you can see them as in the above picture of the cows crossing the road, that is how they are supposed to look. Notice the tail bone – not too prominent; a boney back bone and clearly defined and prominent ribs and a cow is too thin. Remember one has to trend the animals and not just pick out the poor individual who milks her heart out and milks off all her weight. The overall group in the road picture is a nice group of cows, and the ones you can see are all in the same good shape.

Cow Happy Lines

Cow Happy Lines!

The other aspect of a cow’s rib cage area is too look for happy lines, as seen in the close up picture of the rib area of one of the cows. Happy lines resemble veins and appear to the bottom of the rib cage and run opposite angles to the rib bones.

Happy lines are a very good indication that a milk cow is getting everything she needs as it relates to trace minerals and a balanced diet of starch to protein, and is comfortable so that she milks well and the milk is of good quality.

This however is not an indication of the lack of a pathogen presence, but a good manager will have many cows with happy lines, and should have a good testing regime as part of that management process.

Cows on average will be busy but content, laying around often with a goofy look on their face, half asleep, chewing their cud and doing what cows do best, making milk.

Happy lines are just one of many indications of a healthy herd, and I have found I can usually trust a person who does well by their herd.
