Bruce, As we both know, as well as any others who have been a dairyman past or present, there's nothing easy about a dairy operation. It's a 365 days a year job with no days off. I would say it's the most demanding of any farming operation. Makes no difference if you milking two cows or 100, you have to be there twice a day. Well, with 100 cows it takes longer to milk, feed and clean up. You know a whole lot more about the different kinds of bacteria than I do but as rrlund said, all milk has bacteria and it multiplies fast if not handled properly. The faster the milk can be cooled the better, I always believed. I would dump my milk from the milker into a bucket, carry it to the milkhouse, pour it through the strainer into a receiving tank hung from the wall. I have a Gregory milk cooler which consists of rack of pipes that have ice cold water running through the pipes. I pumped the water out of a DeLaval ice bank can cooler. As the ice cold water passed through the rack of pipes it was instantly cooled to ice cold milk then into the jugs. For those who can't understand what these coolers would look like, do a google search for gregory milk cooler and there are images of what they look like. I think they were invented to chill the milk before they went into milk cans before the bulk tank days. I think back then the cold water would be pumped out of a well. I have a 5 can ice bank can cooler that would form a block of ice around a coil of copper tubing and had a circulating propeller that would keep the cold water moving that the cans were submerged in. So, within 1 minute of the milk being dumped out of the milker it was ice cold which I always believed stopped the bacteria growth. Other larger dairies in the area with bulk tanks would dump their milk through a strainer into the bulk tank mixing hot milk with cold. Must have been ok but I wouldn't think it was as good as an instant chill like the plate cooler I used. Maybe nowadays with pipeline systems there is a type of inline cooler to instantly cool the milk before it enters the bulk tank. I'm sure you know all about cooling milk and I'm not trying to educate you, I'm trying to explain how it used to be done for those who don't know. Clean milk is healthy milk and as you mentioned hard work, healthy food and a clean lifestyle is important to a healthy life. I guess I've just been lucky all these years.
A very interesting topic and thank you for your input. Dick
