Holstein cows produce the most milk per day on a weight basis - a healthy 3-year old Holstein at the peak of lactation can produce up to 170 pounds of milk a day (about 21 gallons).
Holsteins were bred to produce more milk than other cows just like Saint Bernards were bred to be large.
holstein cows are known for their high quantity of milk production although other breeds of dairy cattle produce a higher quality or butter fat content than the holstein. the jersey cow is one example of milk cow that produced a lot of cream in the milk.
Holstein dairy cows tend to produce more milk than any animal in the Animal Kingdom except for most whales.
Selective breeding, the farmer will select what bulls to breed to what cows in order to increase milk production.
Female mammals are the only organisms that can produce milk, period.
The Holstein is the largest dairy breed. A mature cow weighs at least 1600 lbs, where as bulls can weigh around 2200 lbs. The Brown Swiss is a close second, with mature weights of cows being around 1400 lbs.
Holstein cows produce an average of 3.5% butterfat with an average of 17,000 pounds of fluid milk per year. That would be 595 pounds of butterfat per year. Holsteins are the highest total fluid milk producers, but are on the low side of percent butterfat and percent protein. Even so, if you compare Holsteins to breeds that produce higher butterfat (like Jerseys and Guernseys), the Holstein will produce more total butterfat in a year due to the higher volume of fluid milk that they produce.
They are identical to the products produced by the Holstein, Gurnsey, Jersey or Brown Swiss. They produce raw milk which is then converted into other dairy products.
Milk production.
Yes. It often signals that the milk production may be decreasing.
