Controlling milk somatic cell count levels
Somatic cell counts are a long-standing marker of milk quality, impacting shelf life and flavor. A lower SCC is better for cheese production and gives a longer shelf life for bottled milk. The national maximum SCC level is , cells per milliliter per farm for domestic . Sep 14, · Somatic cell count (SCC), one of the top indicators of milk quality, can be defined as the total number of cells per milliliter in milk. Primarily, SCC is composed of leukocytes, or white blood cells, that are produced by the cow’s immune system to fight an inflammation in the mammary gland, according to Michael Looper, a professor and the animal science department head at the University of.
There are not many of us can haulers around to do bulk milk. And the state regulations sure don't help any but my question is about somatic cells. How do I keeps my how to reduce somatic cell count in milk somatic cell down without the expensive vet coming to my farm all the time? I also remembered something about bacteria. The faster you cool your milk off the longer it will keep. My Amish farmers have kept milk for two days in 90 degree temperatures, in just well water usually windmill driven.
Some use gas motors. I have how to unlock nokia 106 free question how can the state regulate smc somatic cells, when that, along with bacteria, can and will vary ml to ml.
Even with the most high-tech equipment I have witnessed it vary from to a million cells or bacteria per milliliter. I hope I helped and maybe you can help me. The inflammation of the udder causes large numbers of white blood cells leucocytes and epithelial cells to be released into the milk.
It is these cells that are collectively known as somatic or body cells. The somatic cells are higher just after calving, and they are as a result of mastitis, which of what is the best eco friendly car is the inflammation of the udder. Mastitis however, can occur at any time, whether they are calving or not, and can be classified as Clinical Mastitis, where the udder is hot and swollen and your cow is definitely in some pain.
Temperatures will be high, and the cow will be off her food, and generally looking pretty sorry for herself. However, there is also other forms of mastitis, called Subclinical Mastitis, where there is inflammation to the udder, but it isn't noticeable.
Everything looks normal, but when the milk is tested you have a high somatic cell count. Mastitis is basically an enviromental disease, because the germs that cause it, are in the cow shed. There is no magical way of controlling it, but as I said, you can reduce it by making sure that bedding is regularly replaced, and water sources are clean. Keep your fly population down.
Any dairy equipment used should be clean, and udders totally dry when milking begins. Having said that, mastitis can also be caused by incomplete milking, or improper drying off when it is done too quickly. Most mastitis is caused by germs entering the udder through the teat canal. Therefore the teats should be checked regulary for cracks, cupped teats, enlarged milk ducts, warts, cuts, scratches etc. Of course the milking machines themselves don't do the cows any favors either for mastitis and somatic cell counts.
Often the vacuum rates and fluctuations causes the teats to be irritated, which in turn encourages infection. Using the milking machine on a cow with mastitis, followed by a healthy cow during the same milking session, without any cleaning in between, will result in spreading the infection.
Mastitis occurs when the dairy cow has few defenses agains infection due to either injury, or the sanitary or even mechanical aspects of the milking machines used, how the udders are handled during milking, the type of housing provided and any stress that the animal may be under, can all contribute to mastitis, which, in turn will result in a high somatic cell count.
Therefore, instead of looking at controlling the symptoms, we should be looking at the causes. Good management of your dairy cattle will always work in your favor of keeping the somatic cell count down.
So how do you test for this, without expensive lab tests or vet bills? Firstly, you have to keep production records of your dairy cows and keep a sharp eye out for any loss in productivity from certain cows. Long-term production records is one sure way of knowing what is going on with your cattle. In the old days dairy farmers used a strip cup to examine the first lot of milk stripped from the teat to see if it had any clots, blood, shreds or other particles that would indicate a problem.
If the milk was thin or watery or even yellow in color things were not right. This method is still used today in various places around the world and is a good way of doing a first screening. Testing the milk on a black plate or bowl, improves visibility.
However, although the strip cup tells you there is a problem, it doesn't give you any indication whether your milk falls within the acceptable range for somatic cell counts. Neither does the next test. Farmers would also test the milk to see if what does a pteranodon eat was acid or alkaline using the bromthymol blue test.
The more alkaline the milk, the higher presence of mastitis. Again, this is still in use today. Closer to home, you would have access to the California Mastitis Test CMTbut again this is a screening test, along with a string of others, but doesn't give you the cell count you are after. A more modern and accurate method is to buy yourself a somatic cell check kit. It is simple how to catch gafftopsail catfish effective to use.
You can use it on individual cows, or you can use it to test bulk milk cell counts in the same way. This self testing kit can be used for both Clinical and Subclinical Mastitis. Basically you add your milk sample, then you add a couple of drops of the supplied activator, and then wait 45 minutes for the result. Depending on the severity of the somatic cell count, there will be a variety to the depth of color change in the reaction to the activator.
You are then supplied with a color chart to determine what range your cell count is within. There is also a reader that you can also use, if you wish through which you can insert your test strip and then your result must be multiplied by 1, to get your cell count. For example if you get a reading of. With regards to cooling milk quickly to reduce the occurrence of pathogens, you are right. Pathogen numbers double in the milk every 20 minutes. So the quicker you get the temperature of your milk down to 40 degrees F.
Can't see the Amish keeping the milk at 90 degrees F. This is too high, and not how to store christmas wrapping paper rolls off the temperature of freshly stripped cow's milk.
This should never take more than an hour. The milk not only tastes better, and inhibits the growth of bacteria, but it also retards the ability of the milk to sour. Of course pasteurizing your milk will also do this, but if you prefer raw milk, as I do, pasteurizing ends up not only killing bad bacteria, but good bacteria too!
Again, it comes down to environment. If your dairy cows are out on pasture all day and are only fed grass and hay, and have clean sleeping conditions, there will be a reduction to the chance of pathogens.
As a dairyman, you are responsible for the well-being of your cattle, as well as to the consumer to provide clean milk. Home testing kits have their place, but it is not worth cutting corners when you suspect something more serious.
Laboratory testing, or having your vet call, should never be done away with, as E. Any milk that has a somatic cell count of more than 1, cells per milliliter is not fit for human consumption.

Monitoring somatic cell counts SCC is important in determining the udder health of dairy cows. There are two main types of infections that can raise SCC: contagious and environmental. To control contagious infections, keep infected cows separate and consider adding a universal dry cow therapy to your herd.
For environmental infections, make sure that the animals have clean bedding and that you have a good pre- and post-milking routine. Somatic cell counts are a long-standing marker of milk quality, impacting shelf life and flavor. A lower SCC is better for cheese production and gives a longer shelf life for bottled milk. The national maximum SCC level is , cells per milliliter per farm for domestic sales and , cells per milliliter for exports.
Although somatic cells occur naturally and are not a food safety concern, dairy farmers monitor them because they can be used as a measure of the health of their cows. Processors also pay a premium for milk with low counts. A farmer whose herd has a very low count can receive a significantly higher price per hundredweight compared to a farmer whose herd average is high.
There are some simple and practical steps you can take that can help lower somatic cell counts on your farm. It is important to understand what the situation is on your farm to best manage the issue. Just a few cows with really high individual SCC can skew the entire bulk tank high.
Many cows in the herd with cell counts that stay high on a long term basis can also raise the bulk count. Be sure to look at individual cow reports. This can help you pinpoint problem cows and potentially make culling decisions. Start with a bulk tank culture to find out if the problem is environmental, contagious or something else. The results will narrow down the strategy you should use to combat the issue.
Take bulk tank samples on multiple test days to get the clearest picture of what you're dealing with. Consider culturing some cows individually, especially those that consistently have high SCC or have new infections. Culture results may reveal the presence of contagious organisms like Staph aureus , Strep ag , or mycoplasma.
If this is the case, there are a few key steps you can take to help reduce the spread of these organisms when culling is not an option. Contagious cows should always be milked last to avoid spreading the organisms to non-infected cows. Move infected cows to a different area of the barn or into a different pen. Keeping these cows separate is crucial to reducing the spread of contagious organisms. If culture results reveal high counts of environmental organisms, the goal is to create an environment in which is hard for these organisms to survive.
It's important to keep cows and their bedding clean and dry. It could be worth it to bed twice a day if you notice cows are really getting wet and dirty. Make sure milking equipment is kept clean and spray off any equipment that may get dirty during milking. Taking the time to make sure teats are fully clean will make a huge difference in the presence of environmental organisms.
